Hello all
I've read several posts about 3phase metering etc, but would like to have confirmation/hints on what I plan to use.
1. Does the stackable emonTx V2 have serious disadvantages compared to the V3? I intend to use the V2's as they're about half the price...
2. The mains fuse for the building is 400 Amps, so I have to use bigger CT's. I haven't found clear & simple numbers on what the CT output should be, or the measurement input voltage / resistor combination of the emonTx.
3. I think I read about serial wiring instead of RF to connect the emonTX to the RPi? I want to install everything in the same cabinet in max. 2.5m distance from CT trough emonTx to RPi.
4. The first solution should be fairly easy and fast to set up. But as an engineer myself, I plan on adding to and expand the metering with integration into the home automation system, HVAC, etc... does this sound doable?
thanks, Bill
Re: final questions on planned 3ph, 400A, expandable energy monitor
Hi Bill,
1. There are no serious disadvantages, both are pretty accurate. The v3 was designed to reduce "noise" based inaccuracies at very low measurements, has an additional 4th CT circuit, requires just 1 ac adapter and has a more refined "retail" finish with a nice case etc, but the v2 has a distinct connectivity advantage with the exposed connectors etc and at half the price 3/4 of the CT circuits is still a saving.
2. The calculations are documented in the building blocks under calibration theory if you search the forum for Magnelab you should find several discussions on larger ct's
3. You can only connect 1 serial device to a Pi's gpio serial port, so you would need to use I²C or something to interconnect the Tx's and have at a single serial connection. MartinR's full fat 3phase uses I²C to interconnect 3 emonTx v2's and then transmit RF from the master Tx to Pi, this last stage could be a direct serial connection instead. Alternatively you could make the Pi the master and all the tx's slaves.
4. definitely

Re: final questions on planned 3ph, 400A, expandable energy monitor
hello all i am new to here
can anyone tell me is it 400a per phase that the limit is
so for instance can i use 400 amp cts
if not what is the highest rating that can be used
what needs for to be done for to increase the ct size
Gerry
Re: final questions on planned 3ph, 400A, expandable energy monitor
There is no limit as such. Tell us what your needs are, and we can recommend a suitable CT.
Re: final questions on planned 3ph, 400A, expandable energy monitor
hello Robert
thank you for the reply
ideally i need a ct for to measure 100, 200,400,and 600 amps
i am looking for to measure voltage and kwh and pf if possible
i am looking at multiple boards in a stack so i can measure many 3 ph circuits
what would be the best way to incorporate a stacker for them
Gerry
Re: final questions on planned 3ph, 400A, expandable energy monitor
If you can build the emonTx V2, then it's very simple to stack 3 units, see MartinR's Full-fat 3-phase monitor. You can of course do a similar thing with the V3, but physically it's not so neat.
Note this uses one emonTx per phase, as that allows for the voltage of each phase to be accurately measured. You'd monitor 3 x 3-phase circuits with 3 stacked V2s, or 4 with 3 stacked V3s. More than 3 stacked units could share the voltage references, and then you'd probably want a common 5 V power supply feeding everything (which you'd need anyway with V2s). Using one emonTx to monitor one 3-phase load means you estimate, not measure, the voltage on the second and third phases.
For CTs above 100 A, I usually recommend the Magnelab range, though there are others. These are designed for a 0.333 V output whereas we require a little over 1 V (I usually say 1.1 V is the working maximum), so you need to choose the model without the internal burden resistor, and derate the CT by a factor of 3 (so for 200 A, you need a 600 A CT). You'll need to know the turns ratio (I know some - I must ask Magnelab for a full list) and then calculate a burden resistor to give you the correct voltage at your maximum current. (And that explains why I wrote earlier that there's no maximum - it depends entirely on the CT you choose.)
But you want to steer clear of CTs with 1 A or 5 A secondaries, as you then need a high power off-board burden resistor, and the high VA rating means dangerous voltages and currents should the burden be disconnected for any reason.

SHAH ====================================== 1 Whether Reporters of Local Papers may be allowed to see the judgment ? 2 To be referred to the Reporter or not ? 3 Whether their Lordships wish to see the fair copy of the judgment ? 4 Whether this case involves a substantial question of law as to the interpretation of the constitution of India, 1950 or any order made thereunder ? 5 Whether it is to be circulated to the civil judge ? ====================================== GUJARAT POLLUTION CONTROL BOARD THRO J.V. PANDYA - Petitioner Versus STATE OF GUJARAT & 4 - Respondents ====================================== Appearance : MR SUNIL L MEHTA for the Petitioner. MR KL PANDYA, APP for Respondent No.1. MR PJ KANABAR for Respondent Nos.2 - 4. RULE UNSERVED for Respondent No.5. ====================================== CORAM : HONOURABLE MR.JUSTICE M.R. SHAH Date : 01/03/2012 ORAL JUDGMENT
1. Mr.Sunil Mehta, learned advocate appearing on behalf of the petitioner seeks permission to delete respondent No.5. Permission is accordingly granted.
The present Special Criminal Application under Article 227 of the Constitution of India read with Section 482 of the Code of Criminal Procedure has been preferred by the petitioner herein - original complainant - Gujarat Pollution Control Board to quash and set aside the impugned judgement and order dated 31/07/2007 passed by learned Additional Sessions Judge, Vadodara in Criminal Revision Application No.21 of 2002 as well as order passed by learned Judicial Magistrate, First Class, Savli dated 29/11/2001 passed below Exh-57 in Criminal Case No.984 of 1995, by which, learned Magistrate has discharged respondent Nos.2 to 5 herein - original accused for the offences punishable under Sections 43 and 44 read with 47 of the Water (Prevention and Control of Pollution) Act, 1974 [hereinafter referred to as "the Water Act"] for breach of Sections 24 and 25 of the Water Act.
2. Facts leading to the present petition, in nutshell, are as under:
The petitioner herein - original complainant has filed/instituted Criminal Case No.984 of 1995 against the accused persons for the offences punishable under Sections 43 and 44 read with 47 of the Water Act, who was authorised person to file the complaint for and on behalf of the Gujarat Pollution Control Board. That the learned Magistrate directed to issue summons/ process against the accused persons for the offences punishable under Sections 43 and 44 read with 47 of the Water Act. Thereafter, the accused persons submitted application Exh-57 in Criminal Case No.984 of 1995 before learned Judicial Magistrate, First Class, Savli for discharge solely on the ground that the petitioner, who filed the complaint was not authorised and he cannot be said to have authority to file the complaint. Relying upon decision of the learned Single Judge of this Court reported in 2002(1) GCD 472, learned Magistrate has allowed the said application and discharged the accused persons on the ground that the petitioner was not having authority to file the complaint for and on behalf of the Gujarat Pollution Control Board. Being aggrieved by and dissatisfied with the order passed by learned Judicial Magistrate, First Class, Savli dated 29/11/2001 passed below Exh-57 in Criminal Case No.984 of 1995 in discharging the accused persons, the petitioner herein - original complainant preferred Criminal Revision Application No.21 of 2002 before learned Sessions Court, Vadodara and learned Additional Sessions Judge, Vadodara by order dated 31/07/2007 has been pleased to dismiss the said Criminal Revision Application and has confirmed the order passed by learned Judicial Magistrate, First Class, Savli. Being aggrieved by and dissatisfied with the aforesaid two orders, the petitioner herein - original complainant has preferred the present petition under Article 227 of the Constitution of India.
3. Mr.Sunil Mehta, learned advocate appearing on behalf of the petitioner herein
- original complainant has submitted that the decision of the learned Single Judge reported in 2002(1) GCD 472 (supra), which has been relied upon by both the Courts below, has been set aside by Hon'ble Supreme Court in the case of Gujarat Pollution Control Board V/s. Nicosulf Industries & Exports Private Limited and others reported 2009(2) SCC 171 and it is held that grant of sanction to file the complaint would be in law and authorisation to file the complaint and, therefore, authorisation/ sanction would be a valid if it is given by the State Board. Therefore, it is requested to allow the present petition and to quash and set aside the orders passed by both the Courts below and direct the concerned Magistrate to proceed further with the aforesaid case in accordance with law and on merits.
4. Mr.P.J.Kanabar, learned advocate appearing on behalf of the original accused is not in a position to dispute that the decision of the learned Single Judge, which has been relied upon by both the Courts below, has been set aside by Hon'ble Supreme Court in the case of Nicosulf Industries & Exports Private Limited and others (supra) and he is also not in a position to show any contrary decision to the law laid down by the Hon'ble Supreme Court in the case of Nicosulf Industries & Exports Private Limited and others (supra).
5. Mr.K.L.Pandya, learned Additional Public Prosecutor has supported the learned advocate appearing on behalf of the petitioner herein - original complainant and has requested to allow the present petition.
6. Heard learned advocates appearing on behalf of the respective parties at length. Considering the order passed by learned Judicial Magistrate, First Class, Savli passed below Exh-57 in Criminal Case No.984 of 1995 discharging the accused persons as well as impugned judgement and order dated 31/07/2007 passed by the learned Revisional Court confirming the order passed by learned Judicial Magistrate, First Class, Savli, it appears that both the Courts below have relied upon the decision of the learned Single Judge in the case of Nicosulf Industries & Exports Private Limited and others (Supra) while discharging the accused persons. It is not in dispute that decision of the learned Single Judge rendered in the case of Nicosulf Industries & Exports Private Limited and others (supra) has been set aside by the Hon'ble Supreme Court in the case of Gujarat Pollution Control Board V/s. Nicosulf Industries & Exports Private Limited and others reported in 2009(2) SCC 171 and in Paragraph Nos.16 and 17, the Hon'ble Supreme Court has observed and held as under:
"16. There is no substantial difference in the language of the amended Section
49. The High Court proceeded on the basis that the complaint was illegal since the complaint filed was not duly authorised. Though the High Court proceeded on the basis of amended Section 49, the amended as well as unamended provisions require the State Board to file a complaint or to authorise any of its officers to file the complaint. The authorisation has to be by the State Board. According to the Board, under Section 11-A of the Act it had delegated to the Chairman the power to authorize an officer to file a complaint. The Resolution dated 27-3-1984 refers to the delegation of power for sanctioning prosecution.
17. The High Court has held that the power to sanction a complaint is distinct from the power to authorise the complaint. This view is clearly unsustainable for the reason that if the provisions are construed in the context that as a check over the complaint filed, then the grant of sanction to file a complaint would be in law an authorisation to file the complaint. The stand of the appellant is that the difference between sanction and authorisation in the context of provisions of the Act and in contradistinction to the provisions of IPC and the Code is more semantic than real. The stand is well founded."
7. Under the circumstances, view taken by the learned Single Judge in the case of Nicosulf Industries & Exports Private Limited and others (supra) has not been accepted by Hon'ble Supreme Court and the Hon'ble Supreme Court has held and observed as above. Under the circumstances, the impugned order passed by learned Judicial Magistrate, First Class, Savli discharging the accused persons on the ground that the petitioner, who has filed the impugned complaint was not authorised to file the complaint, cannot be sustained and the same deserves to be quashed and set aside.
8. In view of the above and for the reasons stated hereinabove, the application succeeds. The judgement and order dated 31/07/2007 passed by learned Additional Sessions Judge, Vadodara in Criminal Revision Application No.21 of 2002 as well as order dated 29/11/2001 passed by learned Judicial Magistrate, First Class, Savli below Exh-57 in Criminal Case No.984 of 1995 are hereby quashed and set aside and learned Judicial Magistrate, First Class, Savli is hereby directed to proceed further with Criminal Case No.984 of 1995 in accordance with law and on merits. Rule is made absolute to the aforesaid extent.

Listen: Latest Fantasy Football Podcast discussing all things Sky Sports Fantasy Football
by Sporting LifeTom Carnduff, Billy Lumsden and Aidan Smith are back in their usual Thursday slot to chat all things Sky Sports Fantasy Football.
Jose Mourinho is in at Spurs! Is it time to load up on Tottenham players? Or best to wait a few weeks while we work out what system they will play?
Plenty of games to dissect on Saturday with a number of captaincy choices, so who do you go for? Is it worth looking at Everton? What about Arsenal?
We discuss all that and much more.


I have been experimenting with GBL on a daily basis for almost a week. I found it to be an incredible mood lift, no hangover, that magic 'first-time' ecstasy feeling EVERY time, music sounds great, it seems to get me to REM sleep quicker and I awake very rapidly and straight out of bed (something I never do normally). Plus, boy, does it makes me so horny. I think of the 33ish different drugs I've tried, this has to be one of the most versatile, least comedown, most useful and easily obtainable (and legal) in the UK.
I went to work on it, met customers, performed better. I planned to quit next week for at least 2 weeks to test the withdraw, then after that I had no reason not to continue moderate dosage for some time.
I also managed to procure some Diazepam recently, which as a seperate issue would help some control some mild anxiety issues I have (very mild, sometimes I get nervous about my job, stress, the usual stuff a man can normally handle but why bother when there is a simple chemical alternative).
Yesterday:
9am I woke up feeling a little groggy - but still leapt out of bed. I had consumed some GBL the night previously and as usual, missed the euphoric mark by about 0.5ml and fell asleep on my sofa. It is easy to sneak up on me if I want to continue the high because it seems to last longer than I think, so as I feel like I'm coming down, if I take another single ml hit then an hour later I'm bouncing all over the place and then fall asleep. The weird thing is, I awake perfectly normally 2 hours later - I just come out of the sleep, even if its 3am, I just wake up, then find my bed and go to sleep normally.
So, this morning, 9am upon awaking I decide to take 2 x 5mg Diazepam to take the edge off and start the day. By 11am I had my first job, so I grabbed a glass of water by the side of my bed and downed it. (My room is a total mess with glasses and plates everywhere) I also grabbed the bottle of GBL as I have been using it for quite a long time as a cleaning product! (Believe it or not, that is its intended purpose and it works wonders for my job servicing parts, it was only recently google led me to its intoxicating effect)
12pm I start to feel very strange, but put it down to lack of food, so I purchase a sandwich and go about my day.
1pm I decided to go for a short drive to listen to some new music (my usual route, just in a circle around town).
4pm - I awake. I have no idea where I am. The last 2-3 hours are blank, missing, nada, nothing.. I am aware I am parked somewhere with the engine running but have no idea where. I cannot focus, I cannot talk and I feel incredibly dizzy. The car door opens and a paramedic asks me if I'm okay. 'Sure,' I reply... then proceed to lean out of the door and vomit for about 2 minutes. Five or so nurses put me on a stretcher, stick needles all over me and cart me off to hospital. I am incoherently jabbering at this point. Apparently I had just stopped my car in the middle of the road, slumped at the wheel.
A arrive at the hospital in what seems like 30 seconds, more blood taken. Medical history check. Police *everywhere*. I recovered to a completely normal state in less than an hour and then waiting to be observed for 2 hours. I kept saying everything was totally fine so they dicharged me to the police - 4 hours in the station having fingerprints, mugshots and an interview. They inferred that they did not believe I did not intentionally take GBL, get in a car and drive about. I could only mention something about having it in a glass in my room and must have drunk it before leaving the house. [Approx 2-4ml]
I have since discovered benzodiazepam and dehydration have these noted effects - however I do not know where I stand legally after potential prosecution for driving under the influence. I pretty much date raped myself.
The driving standards authority rule is that if you have a seizure at the wheel, you aren't legally allowed to drive for a year - which would pretty much ruin my life, job, family.. everything. I have read that myoclonic jerks in GBL overdose are often mistaken for seizure, which might be in my favour. But depending on the blood test result (which the police took 6 hours after the incident - meaning it could be in my favour as I hear these substances are metabolised and expelled quite quickly). I will find out in 2 weeks when I get the results, but I will try to claim accidental adverse reaction to this mixture. It certainly WAS NOT my intent to go driving on GBL!! and obviously not to end up in hospital.
One further thing NOT in my favour is the police officer questioned me when I arrived at the hospital, and my story does not match up to what I explained later. But I was totally delirious, and I don't think it's fair that whatever I thought I was saying at the time is relevant.

WORST EXPERIENCE EVER.
Though I still use it, I like it, and despite experiences, if I lose my driving license, I'm going to need something to keep me sane. Moderation is the key.

BJP applecart has started tumbling: Adhir
by Sagar KulkarniAdhir Ranjan Chowdhury, the Leader of the Congress in the Lok Sabha, is known to rustle up controversies with his unique way of putting across his views. On Monday, one such phrase – kiraye ke tattu (rental horses or puppets) — while referring to Members of the European Parliament who visited Kashmir, raised the hackles of the Modi government. In an interview with Sagar Kulkarni of DH, Chowdhury said that the Congress was on a comeback trail, particularly after the assembly elections in Maharashtra and Haryana.
What has changed since the assembly elections in Maharashtra and Haryana?
The Congress is filled with new energy after the assembly elections in Maharashtra and Haryana. Not only in Maharashtra but elsewhere too. And the BJP ranks appear to fall apart. You can see what the Lok Janashakti Party (LJP) is saying, you can see what All Jharkhand Students' Union (AJSU) is saying (about its tie-up with the BJP). The BJP applecart has started tumbling.
So, you say the Congress is on a revival path?
Certainly. If not today, it has to happen tomorrow. It (revival of Congress) is destined to happen.
What will be the role of Rahul Gandhi in the Congress?
You ask this to Rahul Gandhi. I am not his spokesperson. I am a small fry doing the role assigned to me by the party.
Will Rahul Gandhi be back as Congress president?
Why not? Everybody at the party respects Rahul Gandhi.
Your comments kiraye ke tattu raise triggered a furore in the Lok Sabha...
What else do you call persons who were brought to Kashmir with a purpose? All were right-wing party representatives in the European Parliament brought here to paint a certain picture about Kashmir. It is an insult to Indian Parliament that we, the members of Indian Parliament, are not allowed to visit Kashmir and a red carpet is rolled out for Members of European Parliament. Our leaders Rahul Gandhi and Ghulam Nabi Azad were sent back from the airport in Srinagar. Azad had to seek the Supreme Court's intervention to visit Kashmir.
You also wanted Farooq Abdullah and P Chidambaram in Parliament?
Farooq Sahab is a senior member of the Lok Sabha, he has been illegally detained under the Public Safety Act. It is his constitutional right to be in the Lok Sabha when it is in session. Chidambaram should also be allowed to attend Rajya Sabha.
What is the strategy for the Winter Session of Parliament?
We will try and hold the government accountable on a range of issues from the state of the economy to the situation in Jammu and Kashmir. Unemployment, growing pollution in cities, withdrawal of SPG security cover of opposition leaders including former prime minister Manmohan Singh and the Gandhi family, hounding of opposition leaders by central investigative agencies, farmers' problems... we have plenty of issues.
A common complaint of the Opposition is that they don't get adequate time in Parliament.
The Prime Minister never says no to anything. He always says the government is ready for discussion on all issues, but this never gets reflected in Parliament. We, the Opposition, hope that we get adequate time in Parliament to speak and raise issues facing the country.
You are also the chairman of the Public Accounts Committee. What are the priorities of the Committee?
Our top priority is to examine the implementation of the Goods and Services Tax, lack of access to data on various economic parameters, capital acquisition by the Indian Air Force, the performance audit of the crop insurance schemes for farmers, operational preparedness of the Indian Air Force among others.

What You'll Get:
If you haven't already you're going to need to get some brogurt. The best sauces are always made out of free range locally sourced man cream.
Pour your 3 helpings of junkmilk into the cooking pot. Allow to simmer for 5 minutes on low heat. Stir slowly the entire time. This process will remove impurities and even out the properties giving us a good solid base to use in other dude food. We will lose a little volume from this process but worth it for the end result.

Haplotype: For an individual, we have their haplotype information denoted as \(H^1\) and \(H^2\). The haplotype information is obtained throught phasing which requires a external reference (haplotype) panel.
Phenotypes of parents: Besides, we have the phenotypes of their parents. Considering \(P\) phenotypes, we have \(y_{i, p}^f, y_{i, p}^m\).
The goal is to impute the origin of parent for each of the two haplotypes. We denote the origin as \(Z_i\) which represents if \(H_i^1\) comes from father.
We consider a simple model as follow.
\[\begin{aligned} y_{i, p}^f &= (H_i^{f,1} + H_i^{f,2}) \beta_p + \epsilon_{i, p}^f \\ y_{i, p}^m &= (H_i^{m,1} + H_i^{m,2}) \beta_p + \epsilon_{i, p}^m \end{aligned}\]
And we know that one of \(H_i^1\) and \(H_i^2\) comes from father and the other comes from mother. Suppose \(H_i^1\) comes from father and \(H_i^2\) comes from mother, then we can write the haplotype version of the above expressions as follow.
\[\begin{aligned} y_{i, p}^f &= H_i^1 \beta_p + \epsilon_{i, p}^{f,\star} \\ y_{i, p}^m &= H_i^2 \beta_p + \epsilon_{i, p}^{m,\star} \end{aligned}\] where \(\epsilon_{i, p}^{\star}\) contains two parts: 1) environmental noise; and 2) the genetic component of one haplotype. And let \(\epsilon_{i, p}^{\star} \sim N(0, \sigma^2)\).
Essentially, we observe \(H_i^1, H_i^2\) and \(y_{i, p}^f, y_{i, p}^m\) and we’d like to infer \(Z_i\). If we know \(\beta_p\), we can let \(g_{i, p}^k = H_i^k \beta_p\) and we can infer \(Z_i\) by comparing how similar is \((y_{i, 1}^k, \cdots, y_{i, P}^k)\) to \((y_{i, p}^f, \cdots, y_{i, P}^f)\). The uncertainty in estimating \(Z_i\) is accounted for in estimating \(\Pr(Z_i = 1 | \text{data})\). To obtain this quantity, we need to estimate \(\sigma^2\).
However, in practice, we do not observe \(\beta_p\). Instead, we use \(\hat\beta_p\) estimated from GWAS, or more generally, we replace \(g_{i, p}^k\) (the genetic component captured by a haplotype) with any other proxy to it, polygenic risk score.
Here we try a minimal simulation scheme. It contains the following steps:
Some parameter settings:
sample_size = 10000
sample_size_extra = 20000
n_pheno = 30
prior_causal = 0.1
causal_sigma = 1
n_snp = 1000
heritabiltiy = 0.05
maf_low = 0.05
maf_high = 0.45
Simulation.
source('../code/rlib_simulation.R')
maf = get_maf(n_snp, maf_low, maf_high)
h_father = sim_hap(sample_size, n_snp, maf)
h_mother = sim_hap(sample_size, n_snp, maf)
h_gwas = sim_hap(sample_size_extra, n_snp, maf)
h_child = transmit_haplo(h_father, h_mother)
effect_size = matrix(spike_and_slab(n_snp * n_pheno, 1 - prior_causal, causal_sigma), nrow = n_snp, ncol = n_pheno)
y_father = simulate_pheno(h_father, effect_size, heritabiltiy, maf)
y_mother = simulate_pheno(h_mother, effect_size, heritabiltiy, maf)
y_gwas = simulate_pheno(h_gwas, effect_size, heritabiltiy, maf)

Scketch the algorithm.
\[\begin{aligned} Q(\theta | \theta^{(t)}) &= \E_{Z | y, g, \sigma^2}[ \log \Pr(y, g, Z; \sigma^2)] \\ &= \sum_i \E_{Z_i | y_i, g_i, \sigma^2}[\log \Pr(y_i, g_i, Z_i; \sigma^2)] \\ &= \sum_i \E_{Z_i | y_i, g_i, \sigma^2}[\log \Pr(Z_i) + \sum_p \log \Pr(y_{i, p}, g_{i, p}, | Z_i ; \sigma^2)]~\text{, assume iid phenotypes} \\ &= const. + \sum_i \E_{Z_i | y_i, g_i, \sigma^2}[\sum_p \log \Pr(y_{i, p}, g_{i, p}, | Z_i ; \sigma^2)] \end{aligned}\]
And \[\begin{aligned} \log \Pr(y_{i, p}, g_{i, p}, | Z_i ; \sigma^2) &= Z_i F_1(y_{i, p}, g_{i, p}) + (1 - Z_i) F_2(y_{i, p}, g_{i, p}) \\ F_1(y, g) &= l(y^f, g^1) + l(y^m, g^2) \\ F_2(y, g) &= l(y^f, g^2) + l(y^m, g^1) \end{aligned}\]
So, we have \[\begin{aligned} Q(\theta|\theta^{(t)}) &= const. + \sum_i \E_{Z_i | y_i, g_i, \sigma^2}[\sum_p (Z_i F_1(y_{i, p}, g_{i, p}) + (1 - Z_i) F_2(y_{i, p}, g_{i, p}))] \end{aligned}\]
Let \(\E_{Z_i | y_i, g_i, \sigma^2} [Z_i] = w_i\), we have the simplified version. \[\begin{aligned} Q(\theta|\theta^{(t)}) &= const. + \sum_i \sum_p (w_i F_1(y_{i, p}, g_{i, p}) + (1 - w_i) F_2(y_{i, p}, g_{i, p})) \\ &= const. + \sum_i w_i \sum_p F_1(y_{i, p}, g_{i, p}) + \sum_i (1 - w_i) \sum_p F_2(y_{i, p}, g_{i, p}) \end{aligned}\]
To obtain \(w_i\), Bayes rule is applied. \[\begin{aligned} \Pr(Z_i = k | y_i, g_i) &= \frac{\Pr(y_i, g_i | Z_i = k) \Pr(Z_i = k)}{\sum_{k' = 0, 1} \Pr(y_i, g_i | Z_i = k') \Pr(Z_i = k')} \\ \Pr(Z_i = k) ~&~ \text{is based on prior} \\ \log \Pr(y_i, g_i | Z_i) &= \begin{cases} \sum_p F_1(y_{i, p}, g_{i, p}), ~ Z_i = 1 \\ \sum_p F_2(y_{i, p}, g_{i, p}), ~ Z_i = 0 \end{cases} \end{aligned}\]
So the calculation about \(w_i\) concludes the E step. The M step is to update \(\sigma^2\).
\[\begin{aligned} \arg\max_{\sigma^2} Q(\theta | \theta^{(t)}) &= \arg\max_{\sigma} \sum_i w_i \sum_p F_1(y_{i, p}, g_{i, p}) + \sum_i (1 - w_i) \sum_p F_2(y_{i, p}, g_{i, p}) \end{aligned}\]
Here we consider the simplest case in which phenotypes are independent but each phenotype has its own \(\sigma^2\). Essentially, for each phenotype and each individual, we have \[\begin{aligned} l(y, g) &= -\frac{1}{2} \log \sigma^2 - \frac{(y - g)^2}{2 \sigma^2} \end{aligned}\] The optimization stated above is simply a weighted version of sample variance. \[\begin{aligned} \sigma_p^2 \leftarrow \frac{1}{2N}\sum_i w_i [(y_{i, p}^f - y_i^1)^2 + y_{i, p}^m - y_i^2)^2] + (1 - w_i) [(y_{i, p}^m - y_i^1)^2 + (y_{i, p}^f - y_i^2)^2] \end{aligned}\]

 The incident took place in the Gittikhadan police station area on Sunday night when traffic police constable Dhnyaneshwar Chapke was on duty.
The accused, Suraj Kishan Shivarkar (39), a resident of Gaddigodam, has been arrested, they said. According to the police, at around 9 pm, Chapke spotted a bullet motorcycle coming from Katol Road being driven in a reckless way.
As the man was not riding the motorbike properly, the traffic constable stopped him to check whether he was in an inebriated condition, they said. When Chapke and his colleagues tried to check whether Shivarkar was drunk and not, he got angry and abused him, the police said.
Shivarkar was immediately arrested and taken to the nearest police station, they said. He was booked under IPC section 353 (assault or criminal force to deter public servant from discharge of his duty), the police said, adding further investigation was on.

JMS (Java messaging Service) is a standard defined in Java EE to address the producer consumer problem. It standardizes the way of message exchange between two or more system. JMS can be vaguely related to Webservice as they both do the same tasks sending and receiving message. But the main difference lies is Webservice are Synchronous and JMS is asynchronous. Also, we can relate JMS and messaging queues provided different vendor such as WebSphere MQ, ActiveMQ, RabbitMQ etc. AMQP and Microsoft messaging queue does not implement JMS. You can bind JMS inside a EJB same as other locale remote network access using java interfaces, webservices etc. Loos coupling, reliability and asynchronous are main characteristics.
Here are JMS component.
JMS Provider - A system which has implemented JMS specification such as Websphere MQ, RabbitMQ etc.
JMS Client - Application or client which produced/receives message.
JMS producer/publisher - Application or client which produces message.
JMS consumer/subscriber - Application or client which produces message.
JMS Message - A message containing data.
JMS Queue - Queue is provided by providers they maintains the message until the are delivered to destination application.
JMS Topic - Queue is point to point while topic is point to multi point, publish and subscribe model.
You will need a JMS provider server.
You can use Active MQ, Rabbit MQ, Websphere MQ etc, which ever you like and configure few queues in that and get the URL, username password, queue name etc.
Different options to configure JMS
Using Application Server : Since JMS is a specification this is supported by many enterprise level application server for ex IBM Websphere, Weblogic etc. You can configure the JMS URL, queue name, id password etc at Application server level and get it working.
Using Spring Framework : Overall spring tries to reduce the Job for Application server, Spring provides very light option to support Java specification implementation and one of them is JMS. You can choose to use spring framework to configure JMS client and use JMSTemplate to receive or send the message.
Spring Approach.
Add following dependency to your pom.xml.
For Active MQ
For Websphere MQ
Sending Message to Active MQ.
Sending requires, spring jmsTemplate, Spring CachingConnectionFactory and Provider provided connection factory.
Recieving Message from Active MQ.
Receiving requires @EnableJms, Spring DefaultJmsListenerContainerFactory and Provider provided connection.
package com.xyz.jms;
Send & Recive message to Websphere MQ.
Since we are using Spring JMS Websphere MQ started jar, the jmsTemplate is already created which you can use anywhere in your code.
Add @EnableJMS to your configuration class and add the following key value pair in property file.


'[Barr's speech was] one of the most vicious partisan screeds ever uttered by a US cabinet officer,' said one Democratic lawmaker.
Attorney General William Barr is facing calls for his own impeachment, and possible disbarment, over a speech he gave to a conservative group in which he called the Democrats’ push for impeachment a “dangerous holy mission,” HuffPost reports.
As previously reported by The Inquisitr, this week Barr gave a speech to the conservative Federalist Society, during which he made several statements that have raised eyebrows.
For example, he accused Democrats of staging a “scorched-earth, no-holds-barred war of Resistance against this administration… a systematic shredding of norms and undermining the rule of law.” Elsewhere in his speech, he accused elements within the legislative and judicial branches of the government trying to portray themselves as “the good guys,” protecting the country from “a rapacious, would-be autocrat,” and accused Trump’s opponents of carrying out attacks on the president’s “executive authority.”
Barr is now facing calls for his own impeachment, and possibly his disbarment, over his speech.

Former Southern District of New York federal prosecutor Mimi Rocah didn’t mention impeachment or disbarment, but did chastise Barr for acting in a partisan way.
Can Barr Be Impeached For This?
The process for impeaching a federal official is laid out in the Constitution, and it is the same process as it is for the president: namely, that the House of Representatives would vote on Articles of Impeachment, which any voting member of the House can bring to the floor for a vote. If approved by a simple majority vote, the impeached public figure, in this case Barr (hypothetically), would go to the Senate for a trial, where it would take a two thirds majority vote to remove him from office.
As is the case with the impeachment process for the president, it can be initiated for almost any reason, as the Constitution puts few limits on what can and cannot be impeachable offenses.
Loading...
No Attorney General of the U.S. has ever been impeached.
Can He Be Disbarred For This?
Barr is registered with the District of Columbia Bar Association, which does have the power to discipline any of its members. The options for discipline include “informal admonition” on up to full disbarment, and everything in between.
However, for the association to take such action against Barr would first require a formal complaint to be filed. Following, a decision would have to be made on whether or not his actions violated the association’s Code of Conduct.

Introduction
This web application is a JavaScript based assembly simulator. In this section, you will find a mile high overview of assembly. For those already familiar with assembly, jump ahead to the Instruction Definitions section. For a more in-depth and complete understanding of assembly try the wikipedia entry or a variety of the many resources available online.
Assembly Overview
Assembly is a programming language that can be easily converted to a computer processor's language. Generally, the conversion consists of a direct one to one mapping from text form to a sequence of bytes. This sequence of bytes is generally known as machine code which the processor can read directly. Byte code on the other hand is a sequence of bytes that runs on a virtual processor. Given this application uses a virtual processor, the term used in the main memory table of the emulator page is termed byte code instead of machine code.
Generally, assembly is dynamically generated via a compiler that transforms some low level source code such as C to a given assembly language such as ARM or x86. Modern compilers do a really good job of generating optimized assembly code so there are few opportunities where it is truly necessary to write assembly.
Why Learn Assembly?
So why learn assembly? Learning assembly will provide you with an in depth knowledge of how programs operate within the constraints of hardware. To name a few specific reasons:
- Assembly reveals the performance penalty of function calls and the potential risk of stack overflow.
- The presence of condition registers that consequently determine branching and conditionals.
- The challenges and necessity of memory management.
- And more...
Hardware Overview
Assembly is intimately associated with the hardware it is running on. At a bare minimum, a majority of assembly languages typically interact with the following three hardware components:
-
The central processing unit (CPU) is the brain behind the computer (referred to throughout this tutorial as simply the processor). In reality, the CPU recognizes a fixed number of instructions and rotely matches an instruction from the stream of byte coded instructions being fed to it with one of its recognized instructions and executes that instruction.
For this simulator, the CPU is abstracted away in JavaScript and is only visible to you via its memory footprint (see two components below). For more information on CPU's reference the wikipedia entry.
There are a wide variety of processors present hence there is an equally diverse set of assembly languages present. The assembly language used in this emulator is a 16-bit home brew assembly that resembles those used in basic micro controllers.
-
Main memory is the set of memory in which the machine code is stored. Main memory
generally has the following features/purposes:
- Stores the assembly program itself.
- Features a stack at the bottom. The stack is used for function calls and can be used to store temporary data. Stack overflow is when the stack gets too large and overflows into the program or stored data values.
- Can be used by the assembly program to store data while the program is being run.
On your personal machine, this memory is your computers' RAM and the memory management techniques become much more complicated.
This simulator has 512 16-bit memory slots (this may increase to 1024 or more upon greater demand).
-
Registers are a small set of memory that reside in the processor. In this simulator there are four types of registers and seven registers total:
- The Program Counter (PC) which points to the location in memory where the next assembly instruction to execute resides. The SP is bound by the main memory size which in this case is 9 bits wide.
- The Stack Pointer (SP) which points to the location in memory where to deposit the next value in the stack. The SP is bound by the main memory size which in this case is 9 bits wide.
- The registers R0, R1, R2 and R3 are 16-bit general purpose registers that are used to store or output data.
-
The ZCNO register is a four bit condition register which has conditionals that
get set as a result of given instructions. The conditions are detailed in the table
below:
Flag Purpose Z Z stands for zero and gets asserted for given instructions that result in zero. C C stands for carry and gets asserted for given instructions where an arithmetic or logical carry get generated. Logical carry includes left shifting a value who's most significant bit is one and arithmetic carry includes adding two values which exceeds the given 16 bit limit. N N stands for negative and gets asserted for given instructions who's results' most significant bit is one. See 2's complement for explanation. O O stands for overflow and gets asserted for given instructions that result in arithmetic overflow. To summarize arithmetic overflow is when the result exceeds the 16-bit limit and the result gets truncated at 16 bits.
The PC and SP are not directly accessible and can only be manipulated as the result of other instructions that require modifying the PC or SP.

Every assembly language has its own, albeit similar, syntax. The syntax of an assembly language is the grammar the assembly program must be written in accordance to in order for the program to be legally transformed into machine code. The syntax is defined in the following two sections.
Syntax Tokens
This assembly programming language (as with all programming languages) is composed entirely from a combination of a set of tokens. Tokens are the building blocks of a programming language. The six different token types used here are detailed in the table below:
| Green indicates that the token can only be used for arguments. | |
| Pink indicates that the token is optional and does not impact run time. |
| Name | Description |
| Instruction | The instruction is one of the commands that the processor recognizes. Instructions sometimes requires anywhere from 0 to 2 arguments to complete the command. A list of instructions can be found below in the Instruction Set section. |
| Register | This consists of any of R0, R1, R2, and R3. The register can only be used as an argument. |
| Immediate |
Immediates are started with a dollar sign "$" and are followed immediately by a number. An immediate is a constant numeric value in either hexadecimal (prepended with a 0x) or decimal form. Given values exceeding 16 bits in size, the emulator will take the 16 least significant bits. Decimal immediate:
and hexadecimal immediate:
|
| Address |
Addresses are represented as numbers without any decorations. Addresses are available in both hexadecimal and decimal format. Addresses are bound at address 0 at the minimum and 511 as the maximum. Decimal address:
and hexadecimal address:
|
| Label |
Labels are started with a period sign ".", are followed immediately by a name, and must be placed at the beginning of a line. Labels act as a way of naming numbers. They can be used in place of any number (both addresses and immediates).
|
| Comment | Comments are started with a semicolon ";" and continue until the of the line. Comments are used to annotate and describe the code at hand. |
Syntax Format
Line Delimited
This assembly language is line delimited meaning that each new line indicates that there's a new instruction. In other words, putting multiple instructions on a single line will fail to assemble. It is also generally considered to be bad style to have multiple instructions per line.
Comma Delimited Arguments
For instructions that have greater than one argument, a comma is used to separate the arguments.
Here is a generic template for all instructions:
.optional_label INSTRUCTION arg0, arg1 ; Comment which is optional
Register Uses
POP R0 SET R0, R1
Immediate Uses
SET $1234 , R0 SET $0xBEAF, R1
Address Uses
MOV R0 , 500 MOV $0x123, 0x100
Label Uses
To declare a label, it is also acceptable to place the label in the line above the target code.
.LABEL ; Label being set SET 0xA, R0 ; Ensuing instruction(s) ...
To declare a memory location with a label, place the value after the label.
.LABEL 200 ; .LABEL is now associated with 200
Labels can then be used memory would, for instance to branch:
.MUL_FUNCTION MUL R0, R1 RTN ... ; A couple lines later... BRN .MUL_FUNCTION
and can be assigned to an address and used as memory as follows:
.ADDRESS_NAME 100 MOV R0, .ADDRESS_NAME
Labels can be used even if they are declared after being used in their instruction for instance:
BRN .MUL_FUNCTION ... ; A couple lines later... .MUL_FUNCTION MUL R0, R1 RTN
Labels can also be used in immediates, for instance:
.VALUE 100 SET $.VALUE, R0 ; Puts 100 into R0
Instruction Set
Legend
Argument Types
In the table below, the arg0 and arg1 entries will be labeled in accordance to the below table.
| Argument Types | Description |
| - | There is no argument. |
| I | Immediate value. |
| R | Register. |
| A | Address. |
A combination of the letters indicates the argument could be any of the listed argument types.
Example:
Given an arg0 of MR
means that valid arg0 arguments would be
memory and registers.
PC and SP
The PC and SP fields indicates what happens to those registers upon completion of the instruction.
ZCNO
The ZCNO field changes are indicated by the flags that get changed, hence potentially any combination of Z, C, N, and O.
| Condition Status Symbol | Description |
| - | Does not influence this status bit. |
| ? | Conditionally influences the status bit. |
| 0 | Sets the given status bit to 0. |
| 1 | Sets the given status bit to 1. |
Example:
Given an instruction with the following ZCNO code 0?-1
, means that the instruction sets
the zero bit to zero, conditionally sets the carry bit, doesn't change the negative bit, and always
asserts the overflow bit.
Byte Code
There is also a field indicating the byte code(s) of the instruction. A single instruction will have multiple byte codes when it accepts more than a single argument type for any of its arguments. The number of byte codes that such an instruction has is detailed in the table below:
| # of Argument(s) | # of Byte Code(s) |
| 0 | 1 |
| 1 | # of argument types arg0 accepts |
| 2 | (# of argument types arg0 accepts) X (# of argument types arg1 accepts) |
Example:
The SET
instructions' arg0 accepts three argument types: I, R, and
M. SET
's arg1 accepts only a single type, R. Hence, SET has 3 byte codes, one
for the I paired with R, R paired with R, and M paired with M.
Mapping Byte Code
The mapping of the instruction by argument type to its respective byte code is shown below:
Given a targeted instruction, "ins". 1) Take the index of your desired arg0 from the available options for "ins". Let this index be termed "a". 2) Take the index of your desired arg1 from the available options for "ins". Let this index be termed "b". 3) Take the number of possible argument options for arg1 and term this "b_length". 4) The index of the target opcode is: a * b_length + b
Example:
Perform CMP
on a register as arg0 and memory as arg1.
a = 2 b = 1 b_length = 3 index of opcode = 2 * 3 + 1 = 7 opcode = 25

java.lang.Object gr.forth.ics.util.Partition<E>
E
- the type of the arbitrary (user-defined) element associated with a partitionpublic class Partition<E>
Implementation of disjoint-set data structure, providing merge(merge)/find operations, in order to be able to track whether two elements belong in the same set or not, and to efficiently merge two sets.
The set that contains a particular element e
(of type Partition
is accessed by e.find()
.
Note that the returned set is merely an element itself, which is used as a representative of
the set. So, if two elements have the same representative, they belong to the same set.
Otherwise, they belong to different sets. Note that the elements of a particular set cannot be
queried directly. Thus, perhaps confusingly, a Partition
represents both a single
element and potentially a set of elements, in the particular partition happens
to be chosen as the representative of its set.
A partition is initially created as a singleton
.
It accepts an arbitrary (user-defined) value (of type <E>
)
that is permanently associated with the created partition, and can be accessed by value()
.
A created partition is independent from any other created partition. This means that the return value
of find()
is unique, and method areMerged(Partition, Partition)
always returns false when given such a partition as an argument.
A partition p1
may be merged with another partition p2
by
p1.merge(p2);
(or, equivalently, p2.merge(p1);
). From that point on,
this invariant is created: p1.find() == p2.find()
which remains true regardless of
other future merge operations. Similarly, areMerged(p1, p2)
will always return true
.
All methods throw NullPointerException
if given null
arguments.

FILM TITLE: ANDRE DIRECTOR: GEORGE MILLER COUNTRY: USA 1994 CINEMATOGRAPHY: THOMAS BURSTYN MUSIC: BRUCE ROWLAND CAST: Chelsea Field, Keith Carradine, Tina Majorino, Keith Szaarbajka, Aidan Pendleton, Joshua Jackson WRITTEN BY: Based on a true story. SUPER FEATURES: The seal.
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
One thing is for sure when you undertake to see a George Miller film. It will be well written and carefully paged all the way to the end, not leaving many unanswered questions. And it will leave you thinking about the film. Be it Mad Max, the Road Warrior, or things like The Witches of Eastwick, or more recently, Lorenzo's Oil. The scripts may not be the tidiest, or the best, but somehow, this director makes it all look alright, and still come off with a story.
ANDRE is a story for children, but it is also a nice story for adults. It is the story of a seal that got spoiled by a family, that took care of it when it was young. And despite the fact that the man taking care of the seal happens to be the local harbor master, and he is violating rules by keeping an animal captive, he manages to do his job and make a friend here and there. And, during what seems like a bad fishing season, the seal, is being blamed for the poor fishing that all the hard working fishermen are having, or at least for the fact that the harbormaster is more worried about the seal, than he is about the welfare of the fishermen.
In time, the seal ends up going to Boston, some 200 miles from where they are, and becomes a star in an aquarium. But more importantly, Andre becomes a star attraction in the small community, and seems to attract many tourists. And despite a few hang-ups, the devil may care attitude that the seal has, manages to get it and some people in a bit of trouble, but mostly in good humor.
While there is nothing fancy in this film, there is some real nifty shooting in the water watching seals, and Andre do his thing, this film is nice enough to grab your attention. It isn't great, but it is nice. And the kids will love it. Andre is an attention getter, and quite a critic, and tv watcher. And much smarter than we give him, and other seals, credit for.
Worth seeing, make sure the kids see it.

Kogi, Bayelsa elections: PDP senators reject INEC’s results
- PDP senators have rejected the Bayelsa and Kogi governorship elections
- Senate minority leader, Enyinnaya Abaribe, said they rejected the elections because the results announced by INEC did not reflect what actually happened on the field
- However, Senate spokesman, Godiya Akwashiki, said the elections have been conducted as the country’s Electoral Act stipulates and anyone that has grievances “knows what to do”
Days after the Independent National Electoral Commission (INEC) announced winners of the Bayelsa and Kogi governorship elections, senators elected on the platform of the Peoples Democratic Party (PDP) have rejected the poll's results.
The PDP lawmakers made their position regarding the elections known on Wednesday, November 20, at a news conference, the News Agency of Nigeria (NAN) reports.
Legit.ng reports that the candidates of the APC in Bayelsa and Kogi won the gubernatorial elections, according to INEC’s announcements.
Speaking on behalf of the senators, the minority leader of the Senate, Senator Enyinnaya Abaribe, said they were disturbed by the elections.

Ababribe said they rejected the elections, alleging that the results announced by INEC did not reflect what actually happened on the field.
He said: “We want to call the attention of Nigerians. We are very disturbed by the elections that were held last weekend in Bayelsa and Kogi.
“We totally reject the pronouncements after the elections by INEC and we are worried about the trend of what happened during the election.
“We know that the results that were announced were not a true reflection of what happened in the field.”
The minority leader said the elections indicated that the democratic achievements made by the PDP administration since 1999 are being upturned.
However, the elections seem to have left the Senate divided as spokesman of the upper legislative chamber, Senator Godiya Akwashiki, had a different opinion.
In his own reaction, Akwashiki said the elections have been conducted as the country’s Electoral Act stipulates and anyone that has grievances regarding the outcome “knows what to do”.

Meanwhile, Legit.ng earlier reported that Senator Melaye threatened to report Governor Bello and other politicians in Kogi state to the International Criminal Court (ICC) over the alleged violence that occurred during the senatorial and governorship election in the state. Melaye, who is currently battling to get re-elected in the National Assembly, is trailing his opponent, Smart Adeyemi in the Kogi west senatorial district rerun poll.
But the lawmaker, in a post on Twitter on Tuesday, November 19, said what occurred in Kogi state was more of a civil war than an election.

Good things come to those who wait
Learn MoreEmailing back and forth between the teacher and student can be exhausting and complicated for both parties.
The time waiting for the class to be opened or the time waiting for the response from the staff can be reduced with CORSICA's wait-list system!
Current wait-list system allows students who are not on the wailist to register into the course. CORSICA's automatic wait-list management system can fix this problem!
CORSICA is a wait-list management system currently being developed by Old Dominion University's CS411 Red Team. We aim to improve the current CS department's wait-list. CORSICA will provide students and faculty with a friendly web interface which will communicate with the school's central scheduling database. In place of a manual list being keep by advisors, CORSICA will add student to the course's wait-list.
The process is simple. Once the student register with our softwareg, CORSICA will keep track of the list and immediately notify the student once a seat becomes available (via email and text messege, if the student registered their phone number with us). The student will have 24 hours to respond. We believe that this will make the registration process easier for both students and faculty and hope to expand the software throughout the university.


it was saturday night and my friends and i were disappointed that our plans to shroom fell through. the rest of the gang wanted to drink all night, but i don't like to get drunk so i asked if somebody would drive me to the grocery store. i had previously done DayQuill as a drug and thought that i might want to do it again, since drinking wasn't my thing. when i told them what i wanted to get they said, 'shit, man, get dramamine.' i hadn't heard of this before, but after they told me it was like acid but better, i decided to give it a try.
we went to the store at about 11pm and i got some dramamine for myself and a pack of gum for my friend, then we were on our way to taco bell so i could get some drink to down the pills with. i popped the twelve pills in my mouth and took a drink of dr pepper and we went back to the house where the rest of our friends were.
about a half hour later i started feeling a pot-type effect and things started to have a gelatine coating on them. i was still fully aware of what was going on around me and i participated in the conversation. we got up and started walking to the gazebo that was behind the high school, where they wanted to drink. when we got about 20 yards away from the house, i started laughing and wanted to go back and drop my backpack off. by this time, two of the other people with us wanted to get some dramamine for themselves and forget about the drinking situation. we all decided to go back up to the grocery store and get some more DRAMAMINE!
on the way up there, i started seeing patterns and feeling at ease with reality and the world. my mind was in a clear state of being, but i would be saying sentences and forget what i was talking about midway through them. as we were entering the plaza where the store is, i wanted to get out and race with one of the guys in the van and when we did, he started to run while i walked.
i saw a cow and stopped my friend, telling him that there was a black cow in a ravine and how we should go and pick shrooms, then the cow's head turned into a goat head and he tried telling me that there was nothing there. eventually i believed him, i was still understanding that i was on a drug.
while we were in the parking lot waiting for the one getting the dramamine to come up, i struck up a conversation with 4 people in a truck that were all over 30 or 40 and drunk. they were very nice people and the woman that was there seemed concerned about my piercings and kept telling me to be careful because of infections (i have many facial piercings). while i was talking to them, i kept gently easing myself down to the ground, but not meaning to do anything but stand there. my friend kept helping me up and holding me. by this time i was seeing patterns of different things flying over almost everything that i saw.
eventually we got back into the van and drove away.
we ended up at a church where i kept throwing a bag up and down and telling everyone that there was a strobe light effect. i was still conscious of having taken a drug and that was what was maknig me be in this state of mind.
there was also a very pleasurable feeling throughout my body but i was starting to get very thirsty. we ended up downtown talking to some of our other friends and i think that is where i forgot that i was on a drug and where my hallucinations started to become my reality.
after being downtown, the first thing i can remember is being on a road where street construction was going on (i should mention that i am from a small town and it was around 3 in the morning, so there were not many people around for me to bother). i saw two of my friends from school and had a conversation with them and made plans for the next weekend. it was to my suprise that when i called them the next morning, they had not seen me since friday at school. i had conversations with about 30 people that were not there. i also saw about 20 bookbags in the dirt, when really there was just one, which was mine. i remember playing on the construction vehicles and in the dirt and then walking home. the day when i woke up i felt fine, still a little bit of a pot feeling and i was still seeing patterns, but that stopped after i took my shower. i would still see little things every once in a while like black bugs, but it was very rare and about 24 hours later it stopped.
it is now monday after school. i ran into like 5 people that said they saw me at taco bell and i was tripping out. i guess we went back up there after the dramamine took its full effect on me. i spoke with some of the people that i was hanging out with too. i didn't know that i had switched people that i was hanging out with and there were only two of us that were together all night, until they dropped me off when i insisted they drop me off. that is when i was by myself and that is when i was playing in the road construction and having imaginary conversations.
oh yeah, i also had left my backpack in the road construction. i went nuts trying to find it. the police station called today and told me that it was down there and i had to sign to pick it up. i was nervous about getting it since there was an empty bottle of dramamine in the same pocket as my i.d. that they had to see to know it was my backpack, but everything went fine.
i would like to say that THIS IS A VERY VERY STRONG DRUG! what people read on these accounts of dramamine are not made up and are not exaggerated! i haven't read that many reports of this being a very enjoyable drug, but i did enjoy the experience. i do not know how i managed to find my way home by myself without jumping off the bridge that i had to walk across to get from where i was dropped off to my house, and i do not know how i got home without being picked up by police. i remember hearing many people calling my name while i was walking. i think these were the only voices that i heard while on this drug.
i plan to do this again, but i don't think it is an every weekend event, maybe once every 3 or 5 months. very strong and realistic hallucinations, and i think that next time i will be with somebody who is capable of watching me and making sure i don't do something crazy. i would have been very mad if i knew that the people i was with dropped me off while i was tripping out like that, but they were tripping out too so i can't blame them.
anywayz, if you do this drug, have a blast, just be careful!

An R Package for Turning Tweet JSON Files into a Tidyverse-ready Dataframe
Author: Jae Yeon Kim
File an issue if you have problems, questions or suggestions.
Twitter data is an important resource for social science research. (As of July 1, 2020, if you queried “Twitter” in Google Scholar, it returned more than seven million search results.) However, parsing a great deal of Twitter JSON data is not an easy task for researchers with little programming experience. This package provides functions to clean and wrangle Tweet JSON files simply and quickly.
1. Tidying a Tweet JSON file
Most social science researchers have only worked with clearly structured data (e.g., spreadsheets). If one downloads tweets from the Twitter API, these tweets were stored in a semi-structured file format called JSON (JaveScript Object Notation). In simple terms, it has some structure but does not resemble a spreadsheet. With tidytweetjson
, one does not need to understand a JSON file structure. The package helps you to get a tidy data from a Tweet JSON file simply and quickly.
2. Tidying multiple Tweet JSON files
The other challenge is that, often, the number of tweets you want to analyze is large (several GBs or TBs). One way you can work around this problem is to split the JSON file, parse each JSON file into a dataframe, and join them. With tidytweetjson
, one does not need to write a for loop to perform this task. The package helps you to parse and join multiple JSON files into a tidyverse-ready dataframe with just one command.
## Install the current development version from GitHub
devtools::install_github("jaeyk/tidytweetjson",
dependencies = TRUE)
tidytweetjson
should be used in strict accordance with Twitter’s developer terms.
Sign up a Twitter developer account.
Either search for tweets or turn a tweet ID dataset into into tweets (called hydrating) using the Twitter API. I highly recommend using twarc, a command line tool, and Python library to archive Twitter JSON data. Twarc is fast, reliable, and easy to use. If you are using Twarc for the first time, refer to this tutorial. You just need to type one or two commands in the command line to download the Twitter data you want. The followings are examples.
# search
$ twarc search covid19 > search.jsonl
# hydrate
$ twarc hydrate covid19.tsv [hypothetical data] > search.jsonl
jsonl
format; jsonl
extension refers to JSON Lines files. This structure is useful for splitting JSON data into smaller chunks, if it is too large.#Divide the JSON file by 1000 lines (tweets)
# Linux and Windows (in Bash)
$ split -1000 search.jsonl
# macOS
$ gsplit -1000 search.jsonl
If you are a macOS user, you need to install coreutils
by typing brew info coreutils
in a terminal window. You should use gsplit
instead of split
.
If you are a Windows user and you have not installed Bash yet, please install it (here is a guide). Bash allows you to use Linux commands in Windows.
Now, you have a Tweet JSON file or a list of them. Collecting the Tweet JSON file could have has been tedious, especially if you have never done this before. By contrast, turning these files into a tidyverse-ready dataframe is incredibly easy and lightning fast with the help of tidytweetjson
.
The parsed JSON data has a tidy structure. It has nine columns: (user) id
, country_code
(country code), (user) location
, created_at
(time stamp), full_text
(tweets), retweet_count
, favorite_count
, user.followers_count
, and user.friends_count
. Its rows are tweets.
jsonl_to_df()
: Turn a Tweet JSON file into a dataframeAs a test, select one of the JSON files and inspect whether the result is desirable. According to the performance test done by the microbenchmark
package, the jsonl_to_df()
function takes average 5 seconds to turn 1000 tweets into a tidy dataframe.
# Load library
library(tidytweetjson)
# You need to choose a Tweet JSON file
filepath <- file.choose()
# Assign the parsed result to the `df` object
df <- jsonl_to_df(filepath)
jsonl_to_df_all()
: Turn all Tweet JSON files, saved in a directory, into a dataframeAgain, the df_all
object should have nine columns. If your JSON file is heavy (>10GB), I recommend running future::plan("multiprocess")
before using this function to speed up the process. I tested the running time performance using the tictoc package. If you use parallel processing, the jsonl_to_df_all()
function takes 241.68 seconds, or 4 minutes, to turn 1,927,000 tweets into a data frame.
# Load library
library(tidytweetjson)
# You need to designate a directory path where you saved the list of JSON files.
dirpath <- tcltk::tk_choose.dir()
# Parallel processing
n_cores <- availableCores() - 1
plan(multiprocess, # multicore, if supported, otherwise multisession
workers = n_cores) # the maximum number of workers
# Assign the parsed result to the `df_all` object
df_all <- jsonl_to_df_all(dirpath)
add_date()
: Add a date variable that parses Tweet timestamps into date formatcreate_at
variable (Tweet timestamps) is not immediately usable for data modeling and visualization in R. The add_date()
function parses create_at
variable into a new variable called date
that is in the Year-Month-Day date format.
# Add date variable to the data.frame
<- add_date(df)
df
# Head 5 rows of the target and parsed columns

add_US_location()
: Add a dummy variable that identifies whether a Twitter user is located in the USlocation
variable indicates the location of a Twitter user. However, it is difficult to use this variable as Twitter users record their locations in non-unified ways (e.g., Berkeley
, Berkeley, CA
, Berkeley, USA
, The People's Republic of Berkeley
). The add_US_location
function searches whether the string pattern, the location
input, is matched with the names of the major US cities (population greater than about 40000) and states. It also validates the data quality by checking whether the string pattern is not matched with the names of the non-US countries. The function returns a dummy variable called US_location
in which a 1
represents located in the US
, and a 0
represents not located in the US
.
