@Floris van Doorn what are the differences between the local
and localized
keywords? is the main feature being able to re-introduce localized
things into the environment of a separate section?
Yes, that's the idea. localized
basically stores local notation and attribute commands, and gives a convenient way to replay these commands.
Where is localized
documented? I've never heard of it
it's at the bottom of tactics.md
I just had the thought that perhaps Simon's "open all the parser namespaces" tactic could be unified into localized

An attribute is some statement about a program that is true, thus each attribute is a proposition in a logical database of inferred facts.
Note, in comments we use actual field names in the synopsis
section of a function, e.g., section addr size
means that
the section
statement has two fields Scheme.addr
and
Scheme.size
.

Locklizard Safeguard Secure viewer is a secure PDF viewer that is specially designed for its license-protection mechanism on the mutated PDC file format.
PDC file is just like the PDF except users will have to install an authorized license on the Secure Viewer in order to view it. It does only one good thing which is offering great intellectual property security to the document publisher, but most of the time it is causing more annoyance to the readers.
PDC sucks as a reading material
First, the license is not permanent and often limited to the specific amount of devices to activate it at the same time.
Second, all the text in the document is not selectable thus not copyable. Which means no bookmarking and highlighting is allowed.
All in all, user don’t get to own the documents themselves and I don’t like that although this is what the PDC system is designed for.
Convert PDC to PDF
This is the only way that I found working for the PDF conversion at the time of writing this article. We are going to take advantage of the PDC printing function.
Download CutePDF and take note that this is the only working PDf converter software during my test. Install it and open Printer
setting and select Manage
on the CutePDf Writer.
Select Printer properties
, change the printer name to HP Printer
literally, OK
to save the setting. Set this printer as the default printer.
Now open up the PDC file and here is another trick, the PDC file should be virgin which means it was never opened before. Else the printing button will be greyed out. If that is the case, proceed to download the PDC files again from publisher’s source or wherever you get the files from.
Up to here, you should be able to print to PDF format and do whatever you want on it as if the true owner. However, it is advised to keep the extracted version to personal use only, unless you don’t mind to breach all the IP protection against the publisher.
Happy reading!

This New Video Claims Festivals Without Pill Testing Are Basically Leaving Us Blindfolded
by By Alex Bruce-SmithA bold new campaign from Pill Testing Australia says leaving young people to navigate drugs without proper education is akin to letting them leave the house blindfolded.
The campaign, launched ahead of the Aussie festival season, shows a young woman getting ready to go out, putting on a blindfold as her final step. She leaves the house and is almost hit by a car – but thanks to the blindfold, doesn’t even register the near-miss.
When she meets up with her friends outside the festival, it turns out they’re all wearing blindfolds, too. “Don’t leave young people in the dark,” the campaign urges.
The 60-second spot comes less than a month after the NSW Deputy Coroner recommended pill testing be implemented at music festivals, following the deaths of six young people last summer.
Almost half of Australians age 14 and over have tried illicit drugs at least once, according to the campaign, while 15 percent said they have used drugs in the past 12 months.
However, the NSW government has remained staunchly opposed to pill testing, sticking to the decades-old message of “don’t do drugs” instead.
“We think [pill testing] gives people a false sense of security in that, unfortunately – and our heart goes out to families who have lost loved ones under these circumstances – but unfortunately it has been found that at times it is the pure drug, it the pure MDMA, that is killing young people,” premier Gladys Berejiklian told the ABC in October.
That attitude might win boomer votes, but it doesn’t keep people safe. In her findings, Deputy Coroner Harriet Grahame noted that most of the young people who died last summer had received drug education at school, but that it was “of little or no practical help” in the situations they faced.
“By providing pill testing at festivals we can start to remove the blindfolds and provide people with information that we know changes their behaviour,” Pill Testing Australia spokesperson Gino Vumbaca said in a statement.
“By engaging with people who use drugs and by providing scientifically backed knowledge, our pill testing services can achieve a reduction in the number and volume of drugs consumed and consequently reduce harm.”
It’s the second such video from Pill Testing Australia – an outfit made up of medical professionals, harm reduction advocates and former law enforcement officers – in the past six months; the last one compared taking drugs without testing them first as similar to jumping off a cliff without knowing what’s at the bottom.

An empty statement (aka a semicolon by itself) that is not used as the sole body of a for loop or while loop is probably a bug. It could also be a double semicolon, which is useless and should be removed.
This rule is deprecated, use {rule:squid:EmptyStatementUsageCheck} instead.

Fruits
Why are fruits important?
Fruits provide fiber. They also provide many important vitamins and minerals and are low in calories. Fresh, local fruits and in season are best and can be very good value. Eat a variety of coloured fruit – green, yellow, orange, red and purple in order to benefit from the variety of vitamins and minerals provided by each colour group. Include a vitamin C rich fruit each day such as an orange or orange juice, strawberries or blackberries. Count fruit juice and smoothies as only one serving each day as they may be low in fibre. Fruits and fruit juices provide important amounts of vitamins A and C and potassium. They are low in fat and sodium.The Food Guide Pyramid suggests 2 to 4 servings of fruits a day.
The actual portion that you eat
may be bigger or smaller than the
servings listed in the Food Pyramid. For example, one plum
would count as ½ a serving.
What counts as a serving?
1 serving is:
- 1/2 cup of chopped,cooked, or canned fruit
- 1 medium apple, orange,
banana, pear or similar size fruit
- 2 small fruits - plums, kiwis or
similar size fruit
- 10-12 berries, grapes or cherries
- ½ a grapefruit
- 1 heaped dessertspoon of raisins
or sultanas
- 4 dessertspoons of cooked fresh
fruit, fruit tinned in own juice or
frozen fruit
- a small glass (100ml) of
unsweetened fruit juice or a
smoothie made only from fruit.
Here are some selection tips:
- Choose fresh fruits, fruit juices, and frozen, canned, or dried fruit. Pass up fruit canned or frozen in heavy syrups and sweetened fruit juices unless you have calories to spare.
- Eat whole fruits often—they are higher in fiber than fruit juices.
- Have citrus fruits, melons, and berries regularly. They are rich in vitamin C.
- Count only 100 percent fruit juice as fruit. Punches, ades, and most fruit “drinks” contain only a little juice and lots of added sugars. Grape and orange sodas don’t count as fruit juice.
**All age groups need at least 5 servings a day and more, if active.
Women who are pregnant or breastfeeding need 3 servings a day.

JMS 1.1 - April 12, 2002 | |||||||

| SUMMARY: INNER | FIELD | CONSTR | METHOD | DETAIL: FIELD | CONSTR | METHOD |
A client uses a TopicSubscriber
object to receive messages that
have been published to a topic. A TopicSubscriber
object is the
publish/subscribe form of a message consumer. A MessageConsumer
can be created by using Session.createConsumer
.
A TopicSession
allows the creation of multiple
TopicSubscriber
objects per topic. It will deliver each
message for a topic to each
subscriber eligible to receive it. Each copy of the message
is treated as a completely separate message. Work done on one copy has
no effect on the others; acknowledging one does not acknowledge the
others; one message may be delivered immediately, while another waits
for its subscriber to process messages ahead of it.
Regular TopicSubscriber
objects are not durable. They
receive only messages that are published while they are active.
Messages filtered out by a subscriber's message selector will never be delivered to the subscriber. From the subscriber's perspective, they do not exist.
In some cases, a connection may both publish and subscribe to a topic.
The subscriber NoLocal
attribute allows a subscriber to inhibit
the
delivery of messages published by its own connection.
If a client needs to receive all the messages published on a topic,
including the ones published while the subscriber is inactive, it uses
a durable TopicSubscriber
. The JMS provider retains a record of
this durable
subscription and insures that all messages from the topic's publishers
are retained until they are acknowledged by this durable
subscriber or they have expired.
Sessions with durable subscribers must always provide the same client
identifier. In addition, each client must specify a name that uniquely
identifies (within client identifier) each durable subscription it creates.
Only one session at a time can have a TopicSubscriber
for a
particular durable subscription.
A client can change an existing durable subscription by creating a
durable TopicSubscriber
with the same name and a new topic
and/or message
selector. Changing a durable subscription is equivalent to unsubscribing
(deleting) the old one and creating a new one.
The unsubscribe
method is used to delete a durable
subscription. The unsubscribe
method can be used at the
Session
or TopicSession
level.
This method deletes the state being
maintained on behalf of the subscriber by its provider.
Creating a MessageConsumer
provides the same features as
creating a TopicSubscriber
. To create a durable subscriber,
use of Session.CreateDurableSubscriber
is recommended. The
TopicSubscriber
is provided to support existing code.

Customizing report output format is done using feature called recipes. Every report template needs to specify recipe used when rendering report. For example setting report template recipe to phantom-pdf will make report output a be pdf printed using phantomjs screen capture feature. Adding a new recipe is a basic extension point you can hook with your implementation.
jsreport ships out of the box with following recipes.

Please see at http://www.ddi-heatexchangers.com/compts.htm , # 3
3) More Turbulence flow then in Tube or Spiral.
I.e. better Heat Transfer due to zigzag channels.
4) Non-Block design, (no spacers or obstacles as in Spiral type
http://www.ddi-heatexchangers.com/CompSpiral.htm ).
5) Gaps of 3 Inches Minimum, i.e. No Sludge Blockage.
6) No need for expensive Macerator & Blades to grind Sludge.
Savings of about 450,560 $, in 20 years.
http://www.ddi-heatexchangers.com/pcompare.htm
7) Both sides have doors, with full access to internals.
8) Designed for Optimum Height (Non Plug) for each liquid,
9) Designed for Optimum Width, best FAST flows speed, to avoid BAKING.
10) Quotes with Viscosity =1 CPS as others, and with
Computerized, assumed, more realistic Viscosities 4-40 CPS.
11) VERY LOW MAINTENANCE, once in a few years.
(Some competition requires back flush every shift).
12) Can be used in Municipal, Agriculture or Pulp & Paper.
13) Can be manufactured from different metals or alloys.

15) THICKNESS of minimum 0.25 which allows for Corrosion
And ABRASIONS as well.
(Tube HX has sometimes just 1/16 or 1/8 thick inner tube from Stainless Steel,
it is OK against corrosion but NOT ENOUGH allowance against abrasive flow???)
16) HEAT RECOVERY, can have Payback within a year.
http://www.ddi-heatexchangers.com/energy_savings.htm
17) Tested, in continues Use for 9 years in North America,

From : "Cantwell, Joel R."<EMAIL_ADDRESS>To : Erwin Schwartz<EMAIL_ADDRESS>Mr. Schwartz,
HDR has been very pleased with the performance of the DDI heat exchangers that were installed as part of the City of Tulsa Northside WWTP Sludge Pasteurization System. Three types of DDI heat exchangers (two of each for a total of six) were used in the project:
Sludge-to-sludge heat exchangers to recover heat from the pasteurization effluent and use it to preheat the pasteurization influent.
Hot water-to-sludge heat exchangers to take the preheated pasteurization influent up to the required pasteurization temperature.
Cold water-to-sludge heat exchangers to cool the pasteurization effluent after heat recovery down to the proper temperature for the anaerobic digesters
The heat exchangers are a critical component in an effective pasteurization system, especially in making it economically advantageous by recovering the heat.
DDIs products have performed well and have not had any problems.
HDR would specify DDI heat exchangers on other pasteurization projects or in other applications.

Success stories:
DDI has designed and installed Sludge HeatExchangers that have been in operations for as
long as 10 (ten) years without the need for any
maintenance.
Testimonial:
Comparing DDI Cube or Square Heat Recovery tocompetition.
Since DDIs Heat Recovery System has a Minimum
Gap of 2.75" on both sides (to avoid blockage) it
makes no difference which side has Water or
Sludge, or even both sides could have Sludge (for
Heat Recovery).
We achieved our NON-PLUG design (compared to the
Spiral design) via large GAPS, NO OBSTACLES and
ROUND CURVES.
DDI has achieved the possibility of having THE
SAME FLOW in both sides (for Heat Recovery),
compared to Tube and Shell exchangers which
cannot do it (see the SURFACE Heat Transfer area
and FLOW area Comparisons).
DDIs overall size is SMALLER then the Tube and
Shell and does not require Grinders or Macerators
(adds 200,000$ in 10 years) as the Spiral design
does.
We have had 12 Engineers working for many years
to come up with this design and to TEST it in
real life with working units.

From : "Cantwell, Joel R."<EMAIL_ADDRESS>To : Erwin Schwartz<EMAIL_ADDRESS>Mr. Schwartz,
HDR has been very pleased with the performance of the DDI heat exchangers that were installed as part of the City of Tulsa Northside WWTP Sludge Pasteurization System. Three types of DDI heat exchangers (two of each for a total of six) were used in the project:
Sludge-to-sludge heat exchangers to recover heat from the pasteurization effluent and use it to preheat the pasteurization influent.
Hot water-to-sludge heat exchangers to take the preheated pasteurization influent up to the required pasteurization temperature.
Cold water-to-sludge heat exchangers to cool the pasteurization effluent after heat recovery down to the proper temperature for the anaerobic digesters
The heat exchangers are a critical component in an effective pasteurization system, especially in making it economically advantageous by recovering the heat.
DDIs products have performed well and have not had any problems.
HDR would specify DDI heat exchangers on other pasteurization projects or in other applications.

Success stories:
DDI has designed and installed Sludge HeatExchangers that have been in operations for as
long as 10 (ten) years without the need for any
maintenance.
Testimonial:
Comparing DDI Cube or Square Heat Recovery tocompetition.
Since DDIs Heat Recovery System has a Minimum
Gap of 2.75" on both sides (to avoid blockage) it
makes no difference which side has Water or
Sludge, or even both sides could have Sludge (for
Heat Recovery).
We achieved our NON-PLUG design (compared to the
Spiral design) via large GAPS, NO OBSTACLES and
ROUND CURVES.
DDI has achieved the possibility of having THE
SAME FLOW in both sides (for Heat Recovery),
compared to Tube and Shell exchangers which
cannot do it (see the SURFACE Heat Transfer area
and FLOW area Comparisons).
DDIs overall size is SMALLER then the Tube and
Shell and does not require Grinders or Macerators
(adds 200,000$ in 10 years) as the Spiral design
does.
We have had 12 Engineers working for many years
to come up with this design and to TEST it in
real life with working units.

Recipe 4.23. Ensuring a Name Is Defined in a Given ModuleCredit: Steven Cummings ProblemYou want to ensure that a certain name is defined in a given module (e.g., you want to ensure that there is a built-in name set), and, if not, you want to execute some code that sets the definition. SolutionThe solution to this problem is the only good use I've yet seen for statement exec. exec lets us execute arbitrary Python code from a string, and thus lets us write a very simple function to deal with this task: import _ _builtin_ _ def ensureDefined(name, defining_code, target=_ _builtin_ _): if not hasattr(target, name): d = { } exec defining_code in d assert name in d, 'Code %r did not set name %r' % ( defining_code, name) setattr(target, name, d[name]) DiscussionIf your code supports several versions of Python (or of some third-party package), then many of your modules must start with code such as the following snippet (which ensures name set is properly set in either Python 2.4, where it's a built-in, or 2.3, where it must be obtained from the standard library): try: set except NameError: from sets import Set as set This recipe encapsulates this kind of logic directly, and by default works on module _ _builtin_ _, since that's the typical module for which you need to work around missing names in older Python versions. With this recipe, you could ensure name set is properly defined among the built-ins by running just once, during your program's initialization, the single call: ensureDefined('set', 'from sets import Set as set') The key advantage of this recipe is that you can group all needed calls to ensureDefined in just one place of your application, at initialization time, rather than having several ad hoc try/except statements at the start of various modules. Moreover, ensureDefined may allow more readable code because it does only one specific job, so the purpose of calling it is obvious, while try/except statements could have several purposes, so that more study and reflection might be needed to understand them. Last but not least, using this recipe lets you avoid the warnings that the try/except approach can trigger from such useful checking tools as pychecker, http://pychecker.sourceforge.net/. (If you aren't using pychecker or something like that, you should!) The recipe takes care to avoid unintended accidental side effects on target, by using an auxiliary dictionary d as the target for the exec statement and then transferring only the requested name. This way, for example, you can use as target an object that is not a module (a class, say, or even a class instance), without necessarily adding to your target an attribute named _ _builtins_ _ that references the dictionary of Python's built-ins. If you used less care, so that the body of the if statement was only: exec defining_code in vars(target) you would inevitably get such side effects, as documented at http://www.python.org/doc/current/ref/exec.html. It's important to be aware that exec can and does execute any valid string of Python code that you give it. Therefore, make sure that the argument defining_code that you pass to any call of function ensureDefined does not come from an untrusted source, such as a text file that might have been maliciously tampered with. See AlsoThe online documentation of the exec statement in the Python Language Reference Manual at http://www.python.org/doc/current/ref/exec.html. |
