Setting: my friendís house with three of my favorite people
Trip duration: 10:30 PM to 5:30 AM
Experience: first time
10:30 PM- My friends and I stand around the kitchen table and ingest the individual doses of powder. Each of us has never experienced any other psychedelics, so we are apprehensive.
11:00 PM- I am excited and jittery, mostly due to anticipation. One of my friends brought a large roll of paper and acrylic paintsÖ and excellent idea.
11:30 PM- I go upstairs and am drawn to a computer screen saver. A large, red bubble on the screen (actually there) is expanding and contracting. I suddenly become aware of the darkness of the room, and I become extremely claustrophobic. The walls seem to tighten around me. Frightened, I return to the womb that we had created in our friendís basement.
12:00 AM- I start painting, enamored by textures and lines. Painting with these friends seems infinitely important. I find myself writing notes to my future self about the necessity of living in the moment.
12:30 AM- The world seems to swell. Suddenly, painting on the paper doesnít seem like enough. Ordinarily, I am extremely aware of keeping things neat, and I am enjoying this escape; I am enjoying making a complete mess. We are walking in paint. We are painting the doorknobs and the television. We are painting each otherís arms and faces, and backs, andÖ
1:00 AM- I am aware of an overwhelming sense of bliss. We believe that we are experiencing the love of the universe. Paint begins to represent all of the human experience: our movement, our emotions.
1:30 AM-Visuals are fantastic. When dragging paint across the paper, it disappears and reappears and changes colors. The doors are swelling and changing colors. Time doesnít make as much sense. When I look in the mirror, I donít recognize myself. I know that itís me, but I lost my sense of attachment to it. I am in awe of how large my pupils have become, and believe that I can see my soul through my eyes. There is a mutual overwhelming desire to detach our second self, our souls from our bodies.
We decide to venture into a new area of the house. When I touch things, I canít help but gasp. I had forgotten the way that things feel.  In moving my head, the room moves with me for a second. I shower to find my skin under all of the paint, and I realize that itís difficult to distinguish wet from dry. The water feels like tiny fingers running all over my body. I need to close my eyes because the water is pouring towards me from the showerhead so rapidly.
3:30 AM- From here on, I become more introverted. Iím trying to understand the complexities of human nature and emotions. At one point, I am deep in conversation with a friend on the subject of love, but I am distracted by the way his face continues to melt and swirl. I am incapable of being still; constantly shaking or rocking.
Overall, the experience was incredible. There was always an intense body high, but my movements were deliberate and controlled. I never seemed to lose balance or stumble. I felt like I understood everything there was to understand. My omniscience seemed to derive from the infinite wisdom of the universe, as if everything was connected, and I had access to any knowledge that had already been sought. At some times I felt isolated and alone, but the presence of my friends allowed me to escape before I became consumed by the notion.

Protect your npm account with two-factor authentication and read-only tokens
UPDATE: To try out TFA, you’ll need the beta of the npm client. To get it, run `npm install npm@next -g`.
Today, we are announcing two new ways to protect your npm account. Please read on to learn how you can use these security features to keep your code safe and increase everyone’s trust in the more than 550,000 packages of code in the npm Registry.
Two-factor authentication (2FA)
Now, you can sync your npm account with an authentication application like Google Authenticator or Authy. When you log in, you’ll be prompted for a single-use numeric code generated by the app.
2FA is another layer of defense for your account, preventing third parties from altering your code even if they steal or guess your credentials. This is one of the easiest and most important ways to ensure that only you can access to your npm account.
Read-only tokens
If your continuous integration / continuous deployment (CI/CD) workflow includes linking your npm account to tools like Travis CI with authentication tokens, you can now create read-only tokens for tools that don’t need to publish. You can also restrict tokens to work from only specified ranges of IP addresses.
Even if your token is compromised — for example, if you accidentally commit it to GitHub — no one else can alter your code, and only authorized CI servers will be able to download your code.
Set these up now (please)
The npm community is now larger than the population of New York City, so it’s never been more important to reinforce trust and encourage collaboration. Every developer who secures their npm account with these new methods helps ensure the safety and integrity of the code we all discover, share, and reuse to build amazing things.
Learn how to activate 2FA in this doc:
Using Two-Factor Authentication
Watch this space
There has never been a major security incident caused by leaked npm credentials, but our security work is never finished. We work continuously to protect the npm Registry and detect and remove malicious code, and we try to keep you informed of our efforts.
If you ever believe you’ve encountered any malicious code on the Registry or in npm itself, contact us right away [using the npm website](lgt security contact form) or by emailing<EMAIL_ADDRESS>If you have any feedback or questions about what we’ve rolled out today, just contact<EMAIL_ADDRESS>Thanks for helping keep the npm community safe.


Select the PKCS#12 certificate used to authenticate with the service principal.
You can add a Certificate to the Jenkins Credentials store and it will show up in the list.
Note: The certificate will be used only when the Client Secret is not provided.

Here we display a typical way to parametrize (non-relativistic expression) the nuclear two-body force in terms of some operators, the central part, the spin-spin part and the central force. $$ V(\mathbf{r})= \left\{ C_c + C_\mathbf{\sigma} \mathbf{\sigma}_1\cdot\mathbf{\sigma}_2 + C_T \left( 1 + {3\over m_\alpha r} + {3\over\left(m_\alpha r\right)^2}\right) S_{12} (\hat r)\right. $$ $$ \left. + C_{SL} \left( {1\over m_\alpha r} + {1\over \left( m_\alpha r\right)^2} \right) \mathbf{L}\cdot \mathbf{S} \right\} \frac{e^{-m_\alpha r}}{m_\alpha r} $$ How do we derive such terms? (Note: no isospin dependence and that the above is an approximation)
To derive the above famous form of the nuclear force using field theoretical concepts, we will need some elements from relativistic quantum mechanics. These derivations will be given below. The material here gives some background to this. I know that many of you have not taken a course in quantum field theory. I hope however that you can see the basic ideas leading to the famous non-relativistic expressions for the nuclear force.
Furthermore, when we analyze nuclear data, we will actually try to explain properties like spectra, single-particle energies etc in terms of the various terms of the nuclear force. Moreover, many of you will hear about these terms at various talks, workshops, seminars etc. Then, it is good to have an idea of what people actually mean!!

But before we proceed, we will look into specific quantum numbers of the relative system and study expectation vaues of the various terms of $$ V(\mathbf{r})= \left\{ C_c + C_\mathbf{\sigma} \mathbf{\sigma}_1\cdot\mathbf{\sigma}_2 + C_T \left( 1 + {3\over m_\alpha r} + {3\over \left(m_\alpha r\right)^2}\right) S_{12} (\hat r)\right. $$ $$ \left. + C_{SL} \left( {1\over m_\alpha r} + {1\over \left( m_\alpha r\right)^2} \right) \mathbf{L}\cdot \mathbf{S} \right\} \frac{e^{-m_\alpha r}}{m_\alpha r} $$
When solving the scattering equation or solving the two-nucleon problem, it is convenient to rewrite the Schroedinger equation, due to the spherical symmetry of the Hamiltonian, in relative and center-of-mass coordinates. This will also define the quantum numbers of the relative and center-of-mass system and will aid us later in solving the so-called Lippman-Schwinger equation for the scattering problem.
We define the center-of-mass (CoM) momentum as $$ \mathbf{K}=\sum_{i=1}^A\mathbf{k}_i, $$ with \( \hbar=c=1 \) the wave number \( k_i=p_i \), with \( p_i \) the pertinent momentum of a single-particle state. We have also the relative momentum $$ \mathbf{k}_{ij}=\frac{1}{2}(\mathbf{k}_i-\mathbf{k}_j). $$ We will below skip the indices \( ij \) and simply write \( \mathbf{k} \)
In a similar fashion we can define the CoM coordinate $$ \mathbf{R}=\frac{1}{A}\sum_{i=1}^{A}\mathbf{r}_i, $$ and the relative distance $$ \mathbf{r}_{ij}=(\mathbf{r}_i-\mathbf{r}_j). $$
With the definitions $$ \mathbf{K}=\sum_{i=1}^A\mathbf{k}_i, $$ and $$ \mathbf{k}_{ij}=\frac{1}{2}(\mathbf{k}_i-\mathbf{k}_j). $$ we can rewrite the two-particle kinetic energy (note that we use \( \hbar=c=1 \) as $$ \frac{\mathbf{k}_1^2}{2m_n}+\frac{\mathbf{k}_2^2}{2m_n}=\frac{\mathbf{k}^2}{m_n}+\frac{\mathbf{K}^2}{4m_n}, $$ where \( m_n \) is the average of the proton and the neutron masses.
Since the two-nucleon interaction depends only on the relative distance, this means that we can separate Schroedinger's equation in an equation for the center-of-mass motion and one for the relative motion.
With an equation for the relative motion only and a separate one for the center-of-mass motion we need to redefine the two-body quantum numbers.
Previously we had a two-body state vector defined as \( |(j_1j_2)JM_J\rangle \) in a coupled basis. We will now define the quantum numbers for the relative motion. Here we need to define new orbital momenta (since these are the quantum numbers which change). We define $$ \hat{l}_1+\hat{l}_2=\hat{\lambda}=\hat{l}+\hat{L}, $$ where \( \hat{l} \) is the orbital momentum associated with the relative motion and \( \hat{L} \) the corresponding one linked with the CoM. The total spin \( S \) is unchanged since it acts in a different space. We have thus that $$ \hat{J}=\hat{l}+\hat{L}+\hat{S}, $$ which allows us to define the angular momentum of the relative motion $$ { \cal J} = \hat{l}+\hat{S}, $$ where \( { \cal J} \) is the total angular momentum of the relative motion.
To describe the interaction between the various baryons and mesons of the previous table we choose the following phenomenological lagrangians for spin \( 1/2 \) baryons $$ {\cal L}_{ps} =g^{ps}\overline{\Psi}\gamma^{5} \Psi\phi^{(ps)}, $$ $$ {\cal L}_{s} =g^{s}\overline{\Psi}\Psi\phi^{(s)}, $$ and $$ {\cal L}_{v} =g^{v}\overline{\Psi}\gamma_{\mu}\Psi\phi_{\mu}^{(v)} +g^{t}\overline{\Psi}\sigma^{\mu\nu}\Psi\left (\partial_{\mu}\phi_{\nu}^{(v)} -\partial_{\nu}\phi_{\mu}^{(v)}\right), $$ for pseudoscalar (ps), scalar (s) and vector (v) coupling, respectively. The factors \( g^{v} \) and \( g^{t} \) are the vector and tensor coupling constants, respectively.
For spin \( 1/2 \) baryons, the fields \( \Psi \) are expanded in terms of the Dirac spinors (positive energy solution shown here with \( \overline{u}u=1 \)) $$ u(k\sigma)=\sqrt{\frac{E(k)+m}{2m}} \left(\begin{array}{c} \chi\\ \\ \frac{\mathbf{\sigma}\mathbf{k}}{E(k)+m}\chi \end{array}\right), $$ with \( \chi \) the familiar Pauli spinor and \( E(k) =\sqrt{m^2 +|\mathbf{k}|^2} \). The positive energy part of the field \( \Psi \) reads $$ \Psi (x)={\displaystyle \frac{1}{(2\pi )^{3/2}} \sum_{\mathbf{k}\mathbf{\sigma}}u(k\mathbf{\sigma})\exp{-(ikx)}a_{\mathbf{k}\mathbf{\sigma}}}, $$ with \( a \) being a fermion annihilation operator.
Expanding the free Dirac spinors in terms of \( 1/m \) (\( m \) is here the mass of the relevant baryon) results, to lowest order, in the familiar non-relativistic expressions for baryon-baryon potentials. The configuration space version of the interaction can be approximated as $$ V(\mathbf{r})= \left\{ C^0_C + C^1_C + C_\sigma \mathbf{\sigma}_1\cdot\mathbf{\sigma}_2 + C_T \left( 1 + {3\over m_\alpha r} + {3\over \left(m_\alpha r\right)^2} \right) S_{12} (\hat r)\right. $$ $$ + C_{SL}\left. \left( {1\over m_\alpha r} + {1\over \left( m_\alpha r\right)^2} \right) \mathbf{L}\cdot \mathbf{S} \right\} \frac{\exp{-(m_\alpha r)}}{m_\alpha r}, $$ where \( m_{\alpha} \) is the mass of the relevant meson and \( S_{12} \) is the familiar tensor term.
We derive now the non-relativistic one-pion exchange interaction.
Here \( p_{1} \), \( p_{1}' \), \( p_{2} \), \( p_{2}' \) and \( k=p_{1}-p_{1}' \) denote four-momenta. The vertices are given by the pseudovector Lagrangian $$ {\cal L}_{pv}=\frac{f_{\pi}}{m_{\pi}}\overline{\psi}\gamma_{5}\gamma_{\mu} \psi\partial^{\mu}\phi_{\pi}. $$ From the Feynman diagram rules we can write the two-body interaction as $$ V^{pv}=\frac{f_{\pi}^{2}}{m_{\pi}^{2}}\frac{\overline{u}(p_{1}')\gamma_{5} \gamma_{\mu}(p_{1}-p_{1}')^{\mu}u(p_{1})\overline{u}(p_{2}')\gamma_{5} \gamma_{\nu}(p_{2}'-p_{2})^{\nu}u(p_{2})}{(p_{1}-p_{1}')^{2}-m_{\pi}^{2}}. $$
The factors \( p_{1}-p_{1}'=p_{2}'-p_{2} \) are both the four-momentum of the exchanged meson and come from the derivative of the meson field in the interaction Lagrangian. The Dirac spinors obey $$ \begin{eqnarray*} \gamma_{\mu}p^{\mu}u(p)&=&mu(p) \nonumber \\ \overline{u}(p)\gamma_{\mu}p^{\mu}&=&m\overline{u}(p). \nonumber \end{eqnarray*} $$
Using these relations, together with \( \{\gamma_{5},\gamma_{\mu}\}=0 \), we find $$ \begin{eqnarray*} \overline{u}(p_{1}')\gamma_{5}\gamma_{\mu}(p_{1}-p_{1}')^{\mu}u(p_{1}) &=&m\overline{u}(p_{1}')\gamma_{5}u(p_{1})+\overline{u}(p_{1}')\gamma_{\mu} p_{1}'^{\mu}\gamma_{5}u(p_{1}) \nonumber \\ &=&2m\overline{u}(p_{1}')\gamma_{5}u(p_{1}) \nonumber \end{eqnarray*} $$ and $$ \overline{u}(p_{2}')\gamma_{5}\gamma_{\mu}(p_{2}'-p_{2})^{\mu}= -2m\overline{u}(p_{2}')\gamma_{5}u(p_{1}). $$
We get $$ V^{pv}=-\frac{f_{\pi}^{2}}{m_{\pi}^{2}}4m^{2}\frac{\overline{u}(p_{1}') \gamma_{5}u(p_{1})\overline{u}(p_{2}')\gamma_{5}u(p_{2})}{(p_{1}-p_{1}') ^{2}-m_{\pi}^{2}}. $$ By inserting expressions for the Dirac spinors, we find $$ \begin{eqnarray*} \overline{u}(p_{1}')\gamma_{5}u(p_{1})&=&\sqrt{\frac{(E_{1}'+m)(E_{1}+m)} {4m^{2}}}\left(\begin{array}{cc}\chi^{\dagger}&-\frac{\sigma_{1}\cdot{ \bf p_{1}}}{E_{1}' +m}\chi^{\dagger}\end{array}\right)\left(\begin{array}{cc}0&1\\1&0\end{array} \right)\nonumber \\ &&\times \left(\begin{array}{c}\chi\\ \frac{\sigma_{1}\cdot\mathbf{p_{1}}}{E_{1}+m}\chi \end{array}\right) \nonumber \\ &=&\sqrt{\frac{(E_{1}'+m)(E_{1}+m)}{4m^{2}}}\left(\frac{\sigma_{1}\cdot \mathbf{p_{1}}}{E_{1}+m}-\frac{\sigma_{1}\cdot\mathbf{p_{1}'}}{E_{1}'+m}\right) \nonumber \end{eqnarray*} $$
Similarly $$ \overline{u}(p_{2}')\gamma_{5}u(p_{2})=\sqrt{\frac{(E_{2}'+m)(E_{2}+m)} {4m^{2}}}\left(\frac{\sigma_{2}\cdot \mathbf{p}_{2}}{E_{2}+m}- \frac{\sigma_{2}\cdot\mathbf{p'}_{2}}{E_{2}'+m}\right). $$ In the CM system we have \( \mathbf{p}_{2}=-\mathbf{p}_{1} \), \( \mathbf{p'}_{2}= -\mathbf{p'}_{1} \) and so \( E_{2}=E_{1} \), \( E_{2}'=E_{1}' \). We can then write down the relativistic contribution to the NN potential in the CM system: $$ \begin{eqnarray} V^{pv}&=&-\frac{f_{\pi}^{2}}{m_{\pi}^{2}}4m^{2}\frac{1}{(p_{1}-p_{1}')^{2}- m_{\pi}^{2}}\frac{(E_{1}+m)(E_{1}'+m)}{4m^{2}} \nonumber \\ &\times&\left(\frac{\sigma_{1}\cdot\mathbf{p}_{1}}{E_{1}+m}-\frac{\sigma_{1} \cdot\mathbf{p'}_{1}}{E_{1}'+m}\right)\left(\frac{\sigma_{2}\cdot\mathbf{p}_{1}} {E_{1}+m}-\frac{\sigma_{2}\cdot\mathbf{p'}_{1}}{E_{1}'+m}\right). \nonumber \end{eqnarray} $$
In the non-relativistic limit we have to lowest order $$ E_{1}=\sqrt{\mathbf{p}_{1}^{2}+m^{2}}\approx m \approx E_{1}' $$ and then \( (p_{1}-p_{1}')^{2}=-\mathbf{k}^{2} \), so we get for the contribution to the NN potential $$ \begin{eqnarray} V^{pv}&=&-\frac{f_{\pi}^{2}}{m_{\pi}^{2}}4m^{2}\frac{1}{\mathbf{k}^{2}+m^{2}} \frac{2m\cdot 2m}{4m^{2}}\frac{\sigma_{1}}{2m}\cdot(\mathbf{p}_{1}-\mathbf{p'}_{1}) \frac{\sigma_{2}}{2m}\cdot (\mathbf{p}_{1}-\mathbf{p'}_{1}) \nonumber \\ &=&-\frac{f_{\pi}^{2}}{m_{\pi}^{2}} \frac{(\sigma_{1}\cdot\mathbf{k})(\sigma_{2}\cdot\mathbf{k})}{\mathbf{k}^{2}+m_{\pi}^{2}}. \nonumber \end{eqnarray} $$ We have omitted exchange terms and the isospin term \( \mathbf{\tau}_1\cdot\mathbf{\tau}_2 \).
We have $$ V^{pv}(k)=-\frac{f_{\pi}^{2}}{m_{\pi}^{2}} \frac{(\sigma_{1}\cdot\mathbf{k})(\sigma_{2}\cdot\mathbf{k})}{\mathbf{k}^{2}+m_{\pi}^{2}}. $$ In coordinate space we have $$ V^{pv}(r)=\int\frac{d^3k}{(2\pi)^3}e^{i\mathbf{kr}}V^{pv}(k) $$ resulting in $$ V^{pv}(r)=-\frac{f_{\pi}^{2}}{m_{\pi}^{2}} \sigma_{1}\cdot{\nabla}\sigma_{2}\cdot{\nabla} \int\frac{d^3k}{(2\pi)^3}e^{i\mathbf{kr}}\frac{1}{\mathbf{k}^{2}+m_{\pi}^{2}}. $$
We obtain $$ V^{pv}(r)=-\frac{f_{\pi}^{2}}{m_{\pi}^{2}}\sigma_{1}\cdot{\nabla}\sigma_{2}\cdot{\nabla}\frac{e^{-m_{\pi}r}}{r}. $$
Carrying out the differentation of $$ V^{pv}(r)=-\frac{f_{\pi}^{2}}{m_{\pi}^{2}}\sigma_{1}\cdot{\nabla}\sigma_{2}\cdot{\nabla}\frac{e^{-m_{\pi}r}}{r}. $$ we arrive at the famous one-pion exchange potential with central and tensor parts $$ V(\mathbf{r})= -\frac{f_{\pi}^{2}}{m_{\pi}^{2}}\left\{C_{\sigma}\mathbf{\sigma}_1\cdot\mathbf{\sigma}_2+ C_T \left( 1 + \frac{3}{m_\alpha r} + \frac{3}{\left(m_\alpha r\right)^2}\right) S_{12}(\hat r)\right\}\frac{\exp{-m_\pi r}}{m_\pi r}. $$ For the full potential add the exchange part and the \( \mathbf{\tau}_1\cdot\mathbf{\tau}_2 \) term as well. (Subtle point: there is a divergence which gets cancelled by using cutoffs) This leads to coefficients \( C_{\sigma} \) and \( C_T \) which are fitted to data.
When we perform similar non-relativistic expansions for scalar and vector mesons we obtain for the \( \sigma \) meson $$ V^{\sigma}= g_{\sigma NN}^{2}\frac{1}{\mathbf{k}^{2}+m_{\sigma}^{2}}\left (-1+\frac{\mathbf{q}^{2}}{2M_N^2} -\frac{\mathbf{k}^{2}}{8M_N^2}-\frac{\mathbf{LS}}{2M_N^2}\right). $$ We note an attractive central force and spin-orbit force. This term has an intermediate range. We have defined \( 1/2(p_{1}+p_{1}')=\mathbf{q} \). For the full potential add the exchange part and the isospin dependence as well.
We obtain for the \( \omega \) meson $$ V^{\omega}= g_{\omega NN}^{2}\frac{1}{\mathbf{k}^{2}+m_{\omega}^{2}}\left (1-3\frac{\mathbf{LS}}{2M_N^2}\right). $$ We note a repulsive central force and an attractive spin-orbit force. This term has short range. For the full potential add the exchange part and the isospin dependence as well.
Finally for the \( \rho \) meson $$ V^{\rho}= g_{\rho NN}^{2}\frac{\mathbf{k}^{2}}{\mathbf{k}^{2}+m_{\rho}^{2}}\left ( -2\sigma_{1}\sigma_{2}+S_{12}(\hat{k})\right)\tau_{1}\tau_{2}. $$ We note a tensor force with sign opposite to that of the pion. This term has short range. For the full potential add the exchange part and the isospin dependence as well.

Hive Monitor v4: Custom PCB
I’ve learned from my previous prototypes (v1, v2, v3) that the ideal system for monitoring hive conditions would be small and battery operated so that it can be placed inside the hive. My third prototype was the smallest yet, but required cutting away a secion of the bee’s functional honeycomb. Moreover, I had to make them by hand, which doesn’t scale very well. So for this version, I’m going to try and make a printed circuit board with the same functionality.
⚡ Electronics
The basic requirements for this thing are:
- An ESP32, which already has WiFi and Bluetooth built in
- a microphone
- a temperature and humidity sensor
- a method of storing large amounts of data
Based on my previous prototype, I drew up a circuit that seemed like it would work. Then I paid a guy on Fiverr to draw up a PCB to implement that schematic, then had them fabricated somewhere in China. Here’s what the PCB looks like:
As you can see, there’s a microphone, a temp/humidity sensor, and a micro-sd card slot. Initially, I was going to include a micro USB connector, but that would’ve complicated the circuit, and added cost. So instead I decided to use pogo pins on a 3d-printed jig to program the boards.
📦 Enclosure
My previous design required that the honeycomb be cut away, but this one is thin enough that the PCB and battery can be slipped between the frames of the beehive. I modeled the enclosure in Fusion 360, then 3d printed it in yellow PLA.
Firmware
If you’re not interested in software, feel free to skip this section. My prime objective with this version was to reduce power consumption. I ended up spending a lot of time on this, primarily because the ESP32 is a power-hungry monster. Don’t get me wrong, it’s amazingly powerful and dirt cheap, but it’s not well suited for low power battery-operated IoT devices.
Some of the tricks I used to reduce power consumption:
- Using the deep sleep functionality of the ESP32, and using a hardware interrupt timer
- Re-compiling the bootloader to prevent checksumming the program memory on every wake
- Not syncing with WiFi on every wake
- Not writing to the SD card on every wake. Writing to disk is super slow, and there’s a lot of overhead to mount the disk. I’m saving the sensor readings to RTC memory, and pooling disk writes.
- Reducing the size of the audio buffer. This means the sound recording takes up less time (and makes the computation faster). The tradeoff is that you are effectively losing resolution in the output frequency domain (the frequency bin size is higher) but there’s a happy medium.
After all those optimizations, I was able to get the average wake time to under 200mS, which for this hardware is pretty good! Here’s the current on my oscilloscope.
Based on some experimentation and calculations, a 1000mAh battery would power this thing for 1.5 years!
Data Analysis
I’m still collecting data from these sensors, so I think I’ll save the data analysis for another time. Stay tuned!

Rest.li is the top layer of a larger software stack code named ‘pegasus’. Pegasus is comprised of the following major components.
The pegasus data layer provides an in-memory data representation structurally equivalent to JSON, serialization to/from JSON format, and a schema-definition language for specifying data format.
The pegasus data template code generation tool generates type-safe Java APIs for manipulating pegasus data objects.
The pegasus request/response layer provides fully asynchronous abstractions for transport protocols, along with implementations for HTTP based on Netty and Jetty.
The pegasus dynamic discovery layer uses Apache Zookeeper to maintain cluster information. D2 provides client-side software load balancing.
The pegasus Rest.li framework provides a simple framework for building and consuming RESTful resources. Rest.li provides resource patterns that streamline common CRUD use cases for collections of entities and associations between entities.

element, act as if an end tag with the tag name
"option" had been seen.
If the current node is an
optgroup
element, act as if an end tag with the tag
name "optgroup" had been seen.
Insert an HTML element for the token.
First, if the current node is an
option
element, and the node immediately before it in
the stack of open elements is an
optgroup
element, then act as if an end tag with the
tag name "option" had been seen.
If the current node is an
optgroup
element, then pop that node from the stack of open elements. Otherwise, this is a parse error, ignore the token.
If the current node is an
option
element, then pop that node from the stack of open elements. Otherwise, this is a parse error, ignore the token.
If the stack of open elements does not have an element in table scope with the same tag name as the token, this is a parse error. Ignore the token. (fragment case)
Otherwise:
Pop elements from the stack of open elements
until a select
element has been popped from the stack.
Parse error. Act as if the token had been an end tag with the tag name "select" instead.
If the stack of open elements has an element in table scope with the same tag name as that of the token, then act as if an end tag with the tag name "select" had been seen, and reprocess the token. Otherwise, ignore the token.
Parse error. Ignore the token.
Handle the token as follows:
Process the token as it would be processed if the insertion mode was "in body".
Append a Comment
node to the first element in the stack of open elements (the html
element), with the data
attribute set to the data given in the comment
token.
If the parser was originally created as part of the HTML fragment parsing algorithm, this is
a parse error; ignore the token. (The element
will be an html
element in this
case.) (fragment case)
Otherwise, switch to the trailing end phase.
Parse error. Set the insertion mode to "in body" and reprocess the token.
Handle the token as follows:
Append the character to the current node.
Append a Comment
node to the current node with the data
attribute set to the data given in the comment
token.
Insert a
frameset
element for the token.
If the current node is the root html
element, then this is a parse error; ignore the token. (fragment case)
Otherwise, pop the current node from the stack of open elements.
If the parser was not originally created as part of the
HTML fragment parsing algorithm (fragment case), and the current node is no longer a
frameset
element, then change the insertion mode to "after frameset".
Insert an HTML element for the token. Immediately pop the current node off the stack of open elements.
Process the token as if the insertion mode had been "in body".
Parse error. Ignore the token.
Handle the token as follows:
Append the character to the current node.
Append a Comment
node to the current node with the data
attribute set to the data given in the comment
token.
Switch to the trailing end phase.
Process the token as if the insertion mode had been "in body".
Parse error. Ignore the token.
This doesn't handle UAs that don't support frames, or that do support frames but want to show the NOFRAMES content. Supporting the former is easy; supporting the latter is harder.
After the main phase, as each token is emitted from the tokenisation stage, it must be processed as described in this section.
Parse error. Ignore the token.
Append a Comment
node to the Document
object
with the data
attribute set to the data given in
the comment token.
Process the token as it would be processed in the main phase.
Parse error. Switch back to the main phase and reprocess the token.
Once the user agent stops parsing the document, the user agent must follow the steps in this section.
First, the rules for when a script completes loading start applying (script execution is no longer managed by the parser).
If any of the scripts in the list of scripts that
will execute as soon as possible have completed
loading, or if the list of
scripts that will execute asynchronously is not empty and the first
script in that list has completed loading,
then the user agent must act as if those scripts just completed loading,
following the rules given for that in the script
element definition.
Then, if the list of scripts that will execute when the document has finished parsing is not empty, and the first item in this list has already completed loading, then the user agent must act as if that script just finished loading.
By this point, there will be no scripts that have loaded but have not yet been executed.
The user agent must then fire a simple event
called DOMContentLoaded
at the
Document
.
Once everything that delays
the load event has completed, the user agent must fire a load
event at the body
element.
delaying the load event for things like image loads allows for intranet port scans (even without javascript!). Should we really encode that into the spec?
The HTML namespace is:
http://www.w3.org/1999/xhtml
The following steps form the HTML fragment
serialisation algorithm. The algorithm takes as input a DOM
Element
or Document
, referred to as the node, and either returns a string or raises an
exception.
This algorithm serialises the children of the node being serialised, not the node itself.
Let s be a string, and initialise it to the empty string.
For each child node child of the node, in tree order, append the appropriate string from the following list to s:
Element
Append a U+003C LESS-THAN SIGN (<
)
character, followed by the element's tag name. (For nodes created by
the HTML parser, Document.createElement()
, or Document.renameNode()
, the tag name will be
lowercase.)
For each attribute that the element has, append a U+0020 SPACE
character, the attribute's name (which, for attributes set by the HTML parser or by Element.setAttributeNode()
or Element.setAttribute()
, will be lowercase), a U+003D
EQUALS SIGN (=
) character, a U+0022 QUOTATION
MARK ("
) character, the attribute's value,
escaped as
described below, and a second U+0022 QUOTATION MARK ("
) character.
While the exact order of attributes is UA-defined, and may depend on factors such as the order that the attributes were given in the original markup, the sort order must be stable, such that consecutive invocations of this algorithm serialise an element's attributes in the same order.
Append a U+003E GREATER-THAN SIGN (>
)
character.
If the child node is an area
,
base
, basefont
,
bgsound
, br
, col
, embed
,
frame
, hr
, img
, input
, link
, meta
,
param
, spacer
, or
wbr
element, then continue on to the next child node at
this point.
If the child node is a pre
or
textarea
element, append a U+000A LINE FEED (LF)
character.
Append the value of running the HTML
fragment serialisation algorithm on the child
element (thus recursing into this algorithm for that element),
followed by a U+003C LESS-THAN SIGN (<
)
character, a U+002F SOLIDUS (/
) character, the
element's tag name again, and finally a U+003E GREATER-THAN SIGN
(>
) character.
Text
or CDATASection
node
If one of the ancestors of the child node is a style
, script
, xmp
, iframe
, noembed
,
noframes
, noscript
,
or plaintext
element, then append the value of the child node's data
DOM attribute
literally.
Otherwise, append the value of the child node's
data
DOM attribute, escaped as described below.
Comment
Append the literal string <!--
(U+003C LESS-THAN
SIGN, U+0021 EXCLAMATION MARK, U+002D HYPHEN-MINUS, U+002D
HYPHEN-MINUS), followed by the value of the child
node's data
DOM attribute, followed by the
literal string -->
(U+002D HYPHEN-MINUS, U+002D
HYPHEN-MINUS, U+003E GREATER-THAN SIGN).
DocumentType
Append the literal string <!DOCTYPE
(U+003C
LESS-THAN SIGN, U+0021 EXCLAMATION MARK, U+0044 LATIN CAPITAL LETTER
D, U+004F LATIN CAPITAL LETTER O, U+0043 LATIN CAPITAL LETTER C,
U+0054 LATIN CAPITAL LETTER T, U+0059 LATIN CAPITAL LETTER Y, U+0050
LATIN CAPITAL LETTER P, U+0045 LATIN CAPITAL LETTER E), followed by a
space (U+0020 SPACE), followed by the value of the child node's name
DOM attribute,
followed by the literal string >
(U+003E GREATER-THAN
SIGN).
Other nodes types (e.g. Attr
) cannot occur as
children of elements. If they do, this algorithm must raise an
INVALID_STATE_ERR
exception.
The result of the algorithm is the string s.
Escaping a string (for the purposes of the
algorithm above) consists of replacing any occurances of the "&
" character by the string "&
", any occurances of the "<
" character by the string "<
", any occurances of the ">
" character by the string ">
", and any occurances of the ""
" character by the string ""
".
Entity reference nodes are assumed to be expanded by the user agent, and are therefore not covered in the algorithm above.
It is possible that the output of this algorithm, if parsed
with an HTML parser, will not return the original
tree structure. For instance, if a textarea
element to which
a Comment
node has been appended is serialised and
the output is then reparsed, the comment will end up being displayed in
the text field. Similarly, if, as a result of DOM manipulation, an element
contains a comment that contains the literal string "-->
", then when the result of serialising the element
is parsed, the comment will be truncated at that point and the rest of the
comment will be interpreted as markup. More examples would be making a
script
element contain a text node
with the text string "</script>
", or having a p
element that contains a ul
element (as the ul
element's start tag would imply the
end tag for the p
).
The following steps form the HTML fragment
parsing algorithm. The algorithm takes as input a DOM
Element
, referred to as context, which
gives the context for the parser, as well as input, a
string to parse, and returns a list of zero or more nodes.
Parts marked fragment case in algorithms in the parser section are parts that only occur if the parser was created for the purposes of this algorithm. The algorithms have been annotated with such markings for informational purposes only; such markings have no normative weight. If it is possible for a condition described as a fragment case to occur even when the parser wasn't created for the purposes of handling this algorithm, then that is an error in the specification.
Create a new Document
node, and mark it as being an HTML document.
Create a new HTML parser, and associate it with
the just created Document
node.
Set the HTML parser's tokenisation stage's content model flag according to the context element, as follows:
title
or
textarea
element
style
, script
, xmp
, iframe
, noembed
, or
noframes
element
noscript
element
plaintext
element
Switch the HTML parser's tree construction stage to the main phase.
Let root be a new html
element with no attributes.
Append the element root to the
Document
node created above.
Set up the parser's stack of open elements so that it contains just the single element root.
Reset the parser's insertion mode appropriately.
The parser will reference the context node as part of that algorithm.
Set the parser's form
element
pointer to the nearest node to the context that
is a form
element (going straight up the ancestor chain,
and including the element itself, if it is a form
element),
or, if there is no such form
element, to null.
Place into the input stream for the HTML parser just created the input.
Start the parser and let it run until it has consumed all the characters just inserted into the input stream.
Return all the child nodes of root, preserving the document order.
This table lists the entity names that are supported by HTML, and the code points to which they refer. It is referenced by the previous sections.

WYSIWYG editors are authoring tools with a predominantly presentation-driven user interface.
WYSIWYG editors must include a meta
element in the head
element whose name
attribute has the
value generator
and whose content
attribute's value ends with the string
"(WYSIWYG editor)
". Non-WYSIWYG authoring tools must
not include this string in their generator string.
This entire section will probably be dropped. The intent of this section was to allow a way for WYSIWYG editors, which aren't going to use semantic markup, to still write conforming documents, while not letting it be ok for hand-coding authors to not use semantic markup. We still need some sort of solution to this, but it's not clear what it is.
font
elementstyle
interface HTMLFontElement : HTMLElement { readonly attribute CSSStyleDeclaration style; };
This entire section will probably be dropped. The intent of this section was to allow a way for WYSIWYG editors, which don't have enough information to use the "real" "semantic" elements, to still make HTML pages without abusing those semantic elements (since abusing elements is even worse than not using them in the first place). We have still got to find a solution to this, while not letting it be ok for hand-coding authors to abuse the style="" attribute.
The font
element doesn't represent
anything. It must not be used except by WYSIWYG
editors, which may use it to achieve presentational affects. Even
WYSIWYG editors, however, should make every effort to use appropriate
semantic markup and avoid the use of media-specific presentational markup.
Conformance checkers must consider this element to be non-conforming if it is used on a page lacking the WYSIWYG signature.
The following would be syntactically legal (as the output from a WYSIWYG editor, though not anywhere else):
<!DOCTYPE HTML> <html> <head> <title></title> <meta name="generator" content="Sample Editor 1.0 (WYSIWYG editor)"> </head> <body> <font style="display: block; border: solid"> <h1>Hello.</h1> </font> <p> <font style="color: orange; background: white">How</font> <font style="color: yellow; background: white">do</font> <font style="color: green; background: white"><em>you</em></font> <font style="color: blue; background: white">do?</font> </p> </body> </html>
The first font
element is conformant
because h1
and p
elements are both allowed in body
elements. the next four are allowed because
text and em
elements are allowed in
p
elements.
The style
attribute, if specified, must contain only a list of zero or more
semicolon-separated (;) CSS declarations. [CSS21]
We probably need to move this attribute to more elements, maybe even all of them, though if we do that we really should find a way to strongly discourage its use (and the use of its DOM attribute) for non-WYSIWYG authors.
The declarations specified must be parsed and treated as the body of a
declaration block whose selector matches just that font
element. For the purposes of the CSS cascade,
the attribute must be considered to be a 'style' attribute at the author
level.
The style
DOM
attribute must return a CSSStyleDeclaration
whose value
represents the declarations specified in the attribute, if present.
Mutating the CSSStyleDeclaration
object must create a style
attribute on the
element (if there isn't one already) and then change its value to be a
value representing the serialised form of the
CSSStyleDeclaration
object. [CSSOM]
This section will probably include details on how to render DATAGRID (including its pseudo-elements), drag-and-drop, etc, in a visual medium, in concert with CSS. Terms that need to be defined include: sizing of embedded content
CSS UAs in visual media must, when scrolling a page to a fragment identifier, align the top of the viewport with the target element's top border edge.
must define letting the user obtain a physical form of a document (printing) and what this means for the UA
Must define that in CSS, tag names in HTML documents, and class names in quirks mode documents, are case-insensitive.
This section is wrong. mediaMode will end up on Window, I think. All views implement Window.
Any object implement the AbstractView
interface must also
implement the MediaModeAbstractView
interface.
interface MediaModeAbstractView { readonly attribute DOMString mediaMode; };
The mediaMode
attribute on objects
implementing the MediaModeAbstractView
interface
must return the string that represents the canvas' current rendering mode
(screen
, print
, etc). This is a lowercase
string, as defined by the
CSS specification. [CSS21]
Some user agents may support multiple media, in which case there will
exist multiple objects implementing the AbstractView
interface. Only the default view implements the Window
interface. The other views can be reached
using the view
attribute of the
UIEvent
inteface, during event propagation. There is no way
currently to enumerate all the views.
UAs should use the command's Icon as the default generic icon provided
by the user agent when the 'icon' property computes to 'auto' on an
element that either defines a command or refers to one using the command
attribute, but when the property
computes to an actual image, it should use that image instead.
This section is non-normative.
There are certain features that are not handled by this specification because a client side markup language is not the right level for them, or because the features exist in other languages that can be integrated into this one. This section covers some of the more common requests.
If you wish to create localised versions of an HTML application, the best solution is to preprocess the files on the server, and then use HTTP content negotation to serve the appropriate language.
Embedding vector graphics into XHTML documents is the domain of SVG.
Embedding 3D imagery into XHTML documents is the domain of X3D, or technologies based on X3D that are namespace-aware.
This section is expected to be moved to the Window Object specification in due course.
interface WindowTimers { // timers long setTimeout(in TimeoutHandler handler, in long timeout); long setTimeout(in TimeoutHandler handler, in long timeout, arguments...); long setTimeout(in DOMString code, in long timeout); long setTimeout(in DOMString code, in long timeout, in DOMString language); void clearTimeout(in long handle); long setInterval(in TimeoutHandler handler, in long timeout); long setInterval(in TimeoutHandler handler, in long timeout, arguments...); long setInterval(in DOMString code, in long timeout); long setInterval(in DOMString code, in long timeout, in DOMString language); void clearInterval(in long handle); }; interface TimeoutHandler { void handleEvent(arguments...); };
The WindowTimers
interface must
be obtainable from any Window
object
using binding-specific casting methods.
The setTimeout
and setInterval
methods allow authors to
schedule timer-based events.
The setTimeout(handler, timeout[, arguments...])
method takes a reference to a
TimeoutHandler
object and a
length of time in milliseconds. It must return a handle to the timeout
created, and then asynchronously wait timeout
milliseconds and then invoke handleEvent()
on the handler object. If any arguments...
were provided, they must be passed to the handler as
arguments to the handleEvent()
function.
In the ECMAScript DOM binding, the ECMAScript native
Function
type must implement the TimeoutHandler
interface such that
invoking the handleEvent()
method of that interface on the
object from another language binding invokes the function itself, with the
arguments passed to handleEvent()
as the arguments passed to
the function. In the ECMAScript DOM binding itself, however, the
handleEvent()
method of the interface is not directly
accessible on Function
objects. Such functions must be called
in the scope of the browsing context in which
they were created.
Alternatively, setTimeout(code, timeout[, language])
may be used. This variant takes a
string instead of a TimeoutHandler
object. That string must
be parsed using the specified language (defaulting to
ECMAScript if the third argument is omitted) and executed in the scope of
the browsing context associated with the Window
object on which the setTimeout()
method was
invoked.
Need to define language values.
The setInterval(...)
variants
must work in the same way as the setTimeout
variants except that the handler or code
must be
invoked again every timeout milliseconds, not just the
once.
The clearTimeout()
and clearInterval()
methods take one
integer (the value returned by setTimeout
and setInterval
respectively) and must
cancel the specified timeout. When called with a value that does not
correspond to an active timeout or interval, the methods must return
without doing anything.
Timeouts must never fire while another script is executing. (Thus the HTML scripting model is strictly single-threaded and not reentrant.)
In the ECMAScript DOM binding, the ECMAScript
native Function
type must implement the
EventListener
interface such that invoking the
handleEvent()
method of that interface on the object from
another language binding invokes the function itself, with the
event
argument as its only argument. In the ECMAScript
binding itself, however, the handleEvent()
method of the
interface is not directly accessible on Function
objects.
Such functions, when invoked, must be called in the scope of the browsing context that they were created in.
This section will be written in a future draft.

Special thanks to Richard Williamson for creating the first
implementation of canvas
in Safari,
from which the canvas feature was designed.
Special thanks also to the Microsoft employees who first implemented the
event-based drag-and-drop mechanism, contenteditable
, and other features
first widely deployed by the Windows Internet Explorer browser.
Special thanks and $10,000 to David Hyatt who came up with a broken implementation of the adoption agency algorithm that the editor had to reverse engineer and fix before using it in the parsing section.
Thanks also the Microsoft blogging community for some ideas, to the attendees of the W3C Workshop on Web Applications and Compound Documents for inspiration, and to the #mrt crew, the #mrt.no crew, and the cabal for their ideas and support.

Hack-a-what?
So I had the opportunity to participate in my very first hackathon yesterday...and it was awesome. For those of you who have no idea what a hackathon is, it's basically a competition where developers come together to compete for prizes. There are many types of hackathons, each with varying intensities. DevBootCamp's hackathon was of a smaller scale than most but was nonetheless very exciting. I'll go over a brief walkthrough of the day.
09:00 A.M.
Tommy and I arrive at DevBootCamp in San Francisco. Noah's bagels and coffee are available to all participants. I go over to grab a bite. People start streaming in to the meeting room. ~40 people arrive.
10:00 A.M.
DBC Hackathon begins. Rules are explained: people with an idea on what they want to create are given 3 minutes to pitch their idea of the room. At the end of the pitches, developers gather around the idea that sounds most interesting to work on, and the development teams are formed. Whichever team that comes up with the best MVP(minimum viable product) at the end of the hackathon wins. I feel compelled to join a iOS team that wants to create an iphone flashcard app to learn MVC and Swift.
10:45 A.M.
Development teams set up work stations all around DBC. My team of 6 gathers to discuss a plan of attack. We decide on learning the basics of Swift and Apple's IDE: XCode. Groups of 3 are created with one half learning the syntax and the other learning the view and view controllers for user interface. We decide on standups every hour.(A standup is when a team gathers to share information on what they learned and the next steps they should take)
12:30 P.M.
Meeting at a conference room to talk about Playgrounds(Apple's development tool for visualizing view and view controllers as you code.)
02:00 P.M.
Coding begins. I pair up with a team-member to figure out our app's landing page and how to manage transitions between different parts of our app(known as segues in iOS).
04:00 P.M.
Finished landing page and segues. Decide on stretch goal of creating a tabbed page for viewing all flashcards in a deck.
06:00 P.M.
Team that was designing the engine behind flipping a card and randomizing a flashcard has run into a problem. Creating a new flashcard on the new flashcard page does not update our flashcard deck.
07:00 P.M.
Troubleshooting our flashcard problem.
08:40 P.M.
Still troubleshooting. Anxiety starts to sink in. We will be presenting in less than an hour. Call over a developer with experience in Swift to help troubleshoot
09:20 P.M.
Fixed the problem. I add a loading image for our app.
09:30 P.M.
Presentations. Teams show off their mvp. Judges deliberate. We win a prize for creating our app! Winning team created asteroids in Javascript.
It was a very fun experience overall. I'd love to post a page that shows our mvp, but it hasn't been uploaded yet. I'll update this post with my team picture once I get a copy. On a side note, I joined Apple's Developer program to experiment with creating iOS apps as I have time. If you ever have a chance, definitely try going to a hackathon. I thought I wouldn't be able to contribute anything, but it turns out I did! And don't worry about hackathons being too stressful, ours was filled with free bagels, coffee, pizza, and booze(later on in the night as people were finishing their projects.)


Hi, thanks for visiting my page! This page is my personal space to showcase various Web Development projects I will be working on in the coming weeks.
I have ten years of experience working as a Software Developer and I am now in the process of catching up, you can call it upgrading myself,
with web development technologies and JavaScript frameworks by learning the MERN stack and getting myself up to speed with CSS3 and HTML5.
I have learned the hard way, that in the technology field, if you don't keep constantly up-to-date with the latest technologies,
you will quickly fall behind and will be playing catch up. Learning is hard, but keep yourself motivated and on days where things seem bleak,
remind yourself of how much you enjoy what you do and how much you want to keep growing! Motivation is key in this field.
In addition to being passionate about expanding my coding skills, I enjoy learning new technologies, movies, travelling and whenever I find the time, playing video games.
Check out some of the projects I have worked on.
Please feel free to drop me a line via email, or if you prefer, contact me via LinkedIn. You can also check out my GitHub portfolio for additional projects I have not listed on this page.
