This page was created due to a bug in version 2.2.x of the plug-in. This bug caused the plug-in to fail and throw exceptions when running in distributed Jenkins (master and slaves).
Here we list a basic check-list to be followed before releasing a new version of the plug-in, what includes the distributed environment check too as well as other important features to verify before releasing a new version of the plug-in. We believe this will increase the plug-in quality (internal and external).
- Test in distributed environments with Windows and Linux
- Check with latest versions of Jenkins and TestLink
- Check if none help files are missing or pointing to the wrong location
- Check the i18n messages files (new messages added, missing messages, etc)
- Test running package and installing generated hpi file in a jenkins.war or service. We found out that some Javascript errors were caught only during our alpha tests (Thanks Latifa ;-)
- Verify JUnit suite test coverage, as sometimes we add or refactor portions of code and forget to add tests (although we always try to use TDD :-)
- See if there is any new issue in Jenkins' JIRA
- Check if we are using only PNG images
- Test in different browsers (at least FFox, IE8 and Chrome)
- Test using locale plug-in and different languages
- Test all links in the plug-in. Sometimes the sidepanel, floatingBox, config or other jelly file may be broken.
- Test the graph in a Job without anything run yet.
- Check if there is any dependency that could be updated as we specify the dependencies versions in pom.xml
- Run mvn -e -X org.apache.maven.plugins:maven-dependency-plugin::analyze and make sure there are no warnings.
- Make sure disabled tests are not included by the plug-in when seeking results
Feel free to add other steps here if you face problems with the plug-in and believe your suggestion will help us to improve the plug-in quality.
There are other verifications that are done because of a change in Jenkins. Recently it was decided to use PNG instead of GIF images in the project, so we try follow the 'parent project' standard and use PNG's too, instead of GIF's.
Seems that the size of some artifacts being sent to maven repository are too big, and mvn release:perform goal hangs some times. Due to this issue, it is important execute the following command before performing the plug-in release: export MAVEN_OPTS=-Xmx300m.

Organisms that have extreme adaptations are called extremophiles. For example, at low temperatures the giant groundsel (see Section 4.1) produces an anti-freeze type chemical: this stops water in its cells from freezing and damaging the cells.
Extreme characteristics are often found in simple organisms like bacteria: these characteristics take less evolutionary time to develop (see Section X.X) than they would in complex organisms.
Pompeii worms live near deep ocean vents thousands of metres under the sea. These vents release mineral-rich water at temperatures of 80°C or more. The water pressure at this depth can be 100 times that of the surface.
The bacteria that Pompeii worms feed on use chemosynthesis to obtain nutrients from the vents. They have a mechanism that converts chemicals like hydrogen sulfide (H2S) and carbon dioxide (CO2) into simple carbohydrates, a basic food.
Parasitism and mutualism (Edexcel)
Some animals, plants and microorganisms live close to each other because one or both of them use the other to survive. The relationships can work in a variety ways, e.g. between animals and animals, animals and plants, microbes and animals, etc.
A parasitic relationship is where one organism benefits from another ‘host’ organism – often obtaining food – and in some way harms the host. For example, human head lice and tapeworms may live on us or in us (respectively), and are harmful: we function better without them
The parasitic relationship only benefits the parasite. For example, mistletoe grows on host trees, obtaining nutrients and water from them by inserting a special root into the host’s branches. The host gets nothing in return, and may even die.
In mutualism the relationship benefits both organisms. For example, oxpeckers feed on the blood-sucking insects that live on many African animals. This is food for the oxpecker and is useful to the animal; its skin is damaged by the insect parasites.
Another example of a mutually beneficial relationship is between nitrogen-fixing bacteria and legume plants such as peas, beans and soy. The bacteria live inside the legume’s roots.
In this case the relationship is more than just ‘useful’ – it is essential to the survival of both organisms. The plant provides the bacteria with food; the bacteria provides the plant with nitrogen compounds, which are essential for the plant’s growth.

Are you sure that your propagator computes a fixed point? If not, try
returning ES_NOFIX and see if the problem goes away.

The current version of the Music Object API is version 3.4.0.
This version history will allow you to obtain information about the most recent version, as well as other earlier versions of the Music Object API. You can use this information to help you upgrade your content from earlier versions, as well as to understand issues that relate to a version you may be using. We always recommend that you keep your content up-to-date by using the most current version.
To find out which version of Music Object you are currently using, you should locate the file "music-object.js" in the local version of your Web site and then open it in your text editor of choice. Any word processor such as Microsoft Word or Corel WordPerfect will do just fine. Once you have opened up the "music-object.js" file, look right at the top of the file where you will find the version number along with credits and copyright information.
If you are still using an old version of the Music Object API, it is highly recommended that you update all your content before you fall too far behind. If you keep your content up-to-date, you will be less likely to experience problems with your content later when new browser versions or new Player versions are released, or new issues are discovered that need to be remedied by updates of Music Object.
In order to update your content to use the latest version of Music Object, you should go through in sequence all the steps for migrating content, starting from the version you are currently using, and ending at the most recent Music Object version available. The steps for migrating content can be found towards the top of the version history's drop-down list, which is in the version history navigation frame above.
As an example. if your content was still using Music Object version 2.4 and you wished to update it to use Music Object version 3.4.0, then you would have to follow the steps...
Once you had completed these steps, then your content would be ready to use Music Object version 3.4.x.
Along with the "Introduction" link above, there are links for all the Music Object versions that have a documented version history. Version history was started at version 1.1.0. The most recent version always appears at the top of the drop-down list, with version numbers descending from top to bottom.
If you are upgrading from an earlier version of Music Object, you can get an idea of the collective benefits of upgrading by tracking the version histories from the older version that you are currently using, up until the latest version available.

Hi, I upgraded an emoncms to v7 (following https://github.com/emoncms/emoncms -> upgrade) ; I have no error, all is ok.
But I can't find where can I choose redis intead of mysql? I can find only these repositories: mysql, timestore, phptimeseries and the new graphite.
thanks
Re: how to use redis?
no info about redis?
Re: how to use redis?
If you look on the page http://emoncms.org/site/docs/installlinux it tells you about Redis. My understanding is that it's been introduced to speed up the system, and is not a new data store. It just needs to be installed and configured correctly for v7 and then it's work, no need to change any settings (that I know of).
Re: how to use redis?
thank you, I still do not understand the usefulness of redis on emoncmsv7 .. I'll explain: I like so much redis (a beatiful project adopted in different contests), so I'd like to replace timestore with redis.
Re: how to use redis?
hello modenet, redis is currently used for storing metadata rather than historical feed data in emoncms. Things like the last value of a feed and the last time it was updated. These small things actually reduced the amount of reads and writes to disk considerably and so resulted in the performance improvements.
If you can create a redis based feed engine, Id be interested to learn about how you would implement it. Even if there was partial storage or caching of a feed in redis there could be benefits for performance.
Re: how to use redis?

Simulation is a critical part of method development and assessment in quantitative genetics. 'PhenotypeSimulator' allows for the flexible simulation of phenotypes under different models, including genetic variant and infinitesimal genetic effects (reflecting population structure) as well as non-genetic covariate effects, observational noise and additional correlation effects. The different phenotype components are combined into a final phenotype while controlling for the proportion of variance explained by each of the components. For each effect component, the number of variables, their distribution and the design of their effect across traits can be customised. For the simulation of the genetic effects, external genotype data from a number of standard software ('plink', 'hapgen2'/ 'impute2', 'genome', 'bimbam', simple text files) can be imported. The final simulated phenotypes and its components can be automatically saved into .rds or .csv files. In addition, they can be saved in formats compatible with commonly used genetic association software ('gemma', 'bimbam', 'plink', 'snptest', 'LiMMBo').

UK Conservative lead over Labour narrows to 10 points: Panelbase poll
LONDON (Reuters) - British Prime Minister Boris Johnson’s Conservative Party has seen its lead narrow to 10 points over the opposition Labour Party, according to a poll by Panelbase released on Friday, the first time the lead has shrunk in one of its recent surveys.
The Conservatives were on 42%, down one point from the pollster’s survey last week, with Labour on 32%, up 2 points.
The Liberal Democrats were on 14%, down one point, and the Brexit Party was down two points to 3%. Britons go to the polls on Dec. 12.

Placing Lampposts
As a part of the mission �Beautification of Dhaka City�, the government has decided to replace all the old lampposts with new expensive ones. Since the new ones are quite expensive and the budget is not up to the requirement, the government has decided to buy the minimum number of lampposts required to light the whole city.
Dhaka city can be modeled as an undirected graph with no cycles, multi-edges or loops. There are several roads and junctions. A lamppost can only be placed on junctions. These lampposts can emit light in all the directions, and that means a lamppost that is placed in a junction will light all the roads leading away from it.
The �Dhaka City Corporation� has given you the road map of Dhaka city. You are hired to find the minimum number of lampposts that will be required to light the whole city. These lampposts can then be placed on the required junctions to provide the service. There could be many combinations of placing these lampposts that will cover all the roads. In that case, you have to place them in such a way that the number of roads receiving light from two lampposts is maximized.
Input
There will be several cases in the input file. The first line of input will contain an integer T(T<=30) that will determine the number of test cases. Each case will start with two integers N(N<=1000) and M( M<N) that will indicate the number of junctions and roads respectively. The junctions are numbered from 0 to N-1. Each of the next M lines will contain two integers a and b, which implies there is a road from junction a to b,
( 0<= a,b < N ) and a != b. There is a blank line separating two consecutive input sets.
Output
For each line of input, there will be one line of output. Each output line will contain 3 integers, with one space separating two consecutive numbers. The first of these integers will indicate the minimum number of lampposts required to light the whole city. The second integer will be the number of roads that are receiving lights from two lampposts and the third integer will be the number of roads that are receiving light from only one lamppost.
Sample Input

Sample Output
| 2 1 2 1 0 4 |
题目大意：给定一个无向无环图，要求在点上放灯，如果某一点上放了等，则可以照亮与它相通的边，现在要求放尽量少得等，使得所有边都被照亮，并且输出灯数，被照亮两次的边数（即边的两个端点均放置灯），被照亮一次的边。 如果等数一样的话，按照被照亮一次边越大的方案。
解题思路：树形dp，每次枚举某个顶点作为根，对于每个点有放与不放两种可能，均进行考虑；然后每放一盏灯+2000（因为边的最大数量为1000），每增加1条照亮一次的边+1.

For two systems to communicate using IPsec, each must have a connection defined containing the IP address, identifying hostname, RSA key and private network (if any) of both systems. Each configured connection will show up as an icon on the module's main page. Often the configuration details that you enter when creating a connection will be identical on both systems, only with the local and remote section swapped. Every host that wants to communicate using IPsec must have a public/private key pair, used for both encryption and authentication. Each end of a connection must know the other end's public key, which can be either stored in the connection settings or looked up from a DNS server. The Show Public Key feature of this module can be used to display this host's key.
IPsec is more complex to set up that other VPN protocols, but is more secure and capable, and considered the industry standard. Unfortunately, there are many configuration errors that you can make which may cause your connection to fail to start, or to simply silently fail to route traffic. Even though this module protects you from simple mistakes, it cannot save you from more serious conceptual problems.
If you are using FreeSWAN version 2, you will also see icons for editing the various policy files that determine what kind of communication (encrypted or clear) will be used for various networks. Typically these can be left unchanged, as the default is to encrypt whenever possible.
Near the bottom of the page are buttons for starting or stopping the FreeSWAN server process, and applying the current settings when it is running. Your system will be unable to establish or receive IPsec connections unless the server is active. The Start Connection button in this section can be used to force the establishment of an IPsec tunnel that is not automatically brought up when the server is started.

Next: Specialized Lambda Lists, Previous: Ordinary Lambda Lists, Up: Lambda Lists
A generic function lambda list is used to describe the overall shape of the argument list to be accepted by a generic function. Individual method signatures might contribute additional keyword parameters to the lambda list of the effective method.
A generic function lambda list is used by defgeneric.
A generic function lambda list has the following syntax:
| lambda-list | ::= | ({var}* [&optional {var | (var)}*] [&rest var] [&key {var | ({var | (keyword-name var)})}* pt [&allow-other-keys]]) |
A generic function lambda list can contain the lambda list keywords shown in Figure 3–14.
&allow-other-keys &optional &key &rest
Figure 3–14: Lambda List Keywords used by Generic Function Lambda Lists
A generic function lambda list differs from an ordinary lambda list in the following ways:
Zero or more required parameters must be specified.
Optional parameters and keyword parameters may not have default initial value forms nor use supplied-p parameters.
The use of &aux is not allowed.


Trident spouts
Like in the vanilla Storm API, spouts are the source of streams in a Trident topology. On top of the vanilla Storm spouts, Trident exposes additional APIs for more sophisticated spouts.
There is an inextricable link between how you source your data streams and how you update state (e.g. databases) based on those data streams. See Trident state doc for an explanation of this – understanding this link is imperative for understanding the spout options available.
Regular Storm spouts will be non-transactional spouts in a Trident topology. To use a regular Storm IRichSpout, create the stream like this in a TridentTopology:
java
TridentTopology topology = new TridentTopology();
topology.newStream("myspoutid", new MyRichSpout());
All spouts in a Trident topology are required to be given a unique identifier for the stream – this identifier must be unique across all topologies run on the cluster. Trident will use this identifier to store metadata about what the spout has consumed in Zookeeper, including the txid and any metadata associated with the spout.
You can configure the Zookeeper storage of spout metadata via the following configuration options:
transactional.zookeeper.servers
: A list of Zookeeper hostnamestransactional.zookeeper.port
: The port of the Zookeeper clustertransactional.zookeeper.root
: The root dir in Zookeeper where metadata is stored. Metadata will be stored at the path/
Pipelining
By default, Trident processes a single batch at a time, waiting for the batch to succeed or fail before trying another batch. You can get significantly higher throughput – and lower latency of processing of each batch – by pipelining the batches. You configure the maximum amount of batches to be processed simultaneously with the “topology.max.spout.pending” property.
Even while processing multiple batches simultaneously, Trident will order any state updates taking place in the topology among batches. For example, suppose you’re doing a global count aggregation into a database. The idea is that while you’re updating the count in the database for batch 1, you can still be computing the partial counts for batches 2 through 10. Trident won’t move on to the state updates for batch 2 until the state updates for batch 1 have succeeded. This is essential for achieving exactly-once processing semantics, as outline in Trident state doc.
Trident spout types
Here are the following spout APIs available:
- ITridentSpout: The most general API that can support transactional or opaque transactional semantics. Generally you’ll use one of the partitioned flavors of this API rather than this one directly.
- IBatchSpout: A non-transactional spout that emits batches of tuples at a time
- IPartitionedTridentSpout: A transactional spout that reads from a partitioned data source (like a cluster of Kafka servers)
- IOpaquePartitionedTridentSpout: An opaque transactional spout that reads from a partitioned data source
And, like mentioned in the beginning of this tutorial, you can use regular IRichSpout’s as well.


Button Wrapper
Taxation Policy
In a market economy, any state makes extensive use of taxation policy as a certain regulator of the impact on the adverse events of the market. Taxes, as well as the whole tax system, are a powerful tool to manage the economy under market conditions. As an instrument of redistribution, taxes should extinguish the arising failures of the distribution system and encourage people in the development of some form of activity.

18 * ======== Diags ========
19 * Diagnostics manager
20 *
21 * Every XDC module has a "diagnostics mask" that allows clients to
22 * enable or disable diagnostics on a per module basis both at
23 * configuration time and at runtime. The `Diags` module manages a
24 * module's diagnostics mask.
25 *
26 * You use the `Diags` module to set and clear bits in a module's
27 * diagnostics mask for the purpose of controlling diagnostics
28 * within that module. Each bit corresponds to a "category" of diagnostic
29 * that can be individually enabled or disabled.
30 *
31 * A module's diagnostics mask controls both `{@link Assert}` and
32 * `{@link Log}` statements within that module. A module's diagnostics
33 * mask may also be used to conditionally execute blocks of code using
34 * the `{@link #query Diags_query()}` runtime function.
35 *
36 * A module's diagnostics mask can be set at configuration time and
37 * at runtime. The implementation of diagnostics is such that when they
38 * are permanently turned off at configuration time
39 * (`{@link #ALWAYS_OFF Mode.ALWAYS_OFF}`), an optimizer can
40 * completely eliminate the diagnostics code from the program. Similarly,
41 * if diagnostics are permanently turned on at configuration time
42 * (`{@link #ALWAYS_ON Mode.ALWAYS_ON}`), the optimizer can
43 * eliminate all runtime conditional checking and simply
44 * invoke the diagnostics code directly. Runtime checking of the
45 * diagnostics mask is performed only when the diagnostics are configured
46 * to be runtime modifiable (`{@link #RUNTIME_OFF Mode.RUNTIME_OFF}` or
47 * `{@link #RUNTIME_ON Mode.RUNTIME_ON}`).
48 *
49 * Each bit of the diagnostics mask is controlled by one of the following
50 * constants.
51 *
52 * @p(code)
53 * Constant Meaning
54 * --------------------------
55 * ENTRY Function entry
56 * EXIT Function exit
57 * LIFECYCLE Object life-cycle
58 * INTERNAL Internal diagnostics
59 * ASSERT Assert checking
60 * STATUS Warning or Error events
61 * USER1 User defined diagnostics
62 * USER2 User defined diagnostics
63 * USER3 User defined diagnostics
64 * USER4 User defined diagnostics
65 * USER5 User defined diagnostics
66 * USER6 User defined diagnostics
67 * USER7 User defined diagnostics
68 * INFO Informational event
69 * USER8 User defined diagnostics
70 * ANALYSIS Analysis event
71 * @p
72 *
73 * These constants can be used from either JavaScript configuration
74 * scripts or C code and, therefore, have two "names". For example,
75 * to reference the ENTRY constant from JavaScript you must use
76 * `Diags.ENTRY` whereas from C you would use `Diags_ENTRY`.
77 *
78 * The `ENTRY` and `EXIT` categories are for log statements at the entry and
79 * exit points, respectively, to each function within a module. This
80 * is useful for tracking the execution flow of your program.
81 *
82 * The `LIFECYCLE` category is for log events at the create/construct
83 * and delete/destruct points of each instance object for the module.
84 * This is useful for tracking the life-cycle of a module instance object.
85 *
86 * `ASSERT` and `INTERNAL` are unique in that they are not related to logging,
87 * but instead control the Assert statements in a module. These categories
88 * control the two classes of asserts:
89 *
90 * @p(blist)
91 * - Public asserts, which have an `{@link Assert#Id Assert_Id}` and
92 * are documented in the module's reference pages. These asserts are
93 * on by default and are meant to help developers validate code that
94 * invokes a module's functions.
95 * - Internal asserts, which have no `{@link Assert#Id Assert_Id}`.
96 * These asserts are off by default and are typically used only when
97 * developing code. That is, like the standard C assert() mechanism,
98 * these asserts are not part of a deployed application.
99 * @p
100 *
101 * When a module has enabled the `ASSERT` category (which is enabled by
102 * default) in its diagnostics mask, the module executes all of its public
103 * assert statements. To enable internal asserts, you must enable both the
104 * `ASSERT` and `INTERNAL` categories.
105 *
106 * The `ASSERT` and `INTERNAL` categories are not intended for use as log
107 * event categories. If an event is defined with either of these categories,
108 * you will receive a validation error during configuration.
109 *
110 * The `STATUS` category is used for error and warning type events. The
111 * four event levels within the `STATUS` category have defined meanings,
112 * see {@link #EMERGENCY}
113 *
114 * The `INFO` category is used for generic informational events. Any event
115 * which does not belong to a more specific category of events may simply
116 * be an `INFO` event.
117 *
118 * The `ANALYSIS` category is used for events related to benchmarks and
119 * performance analysis.
120 *
121 * The `USER1`-`6` categories are available to each module writer to use as
122 * he or she wishes.
123 *
124 * The USER7 and USER8 categories are still defined, but their bits have been
125 * repurposed for the INFO and ANALYSIS categories, respectively, so the use
126 * of USER7 and USER8 has been deprecated.
127 *
128 * @a(Examples)
129 * Configuration example: The following XDC configuration statements set
130 * a module's diagnostics mask in a configuration script. (In this case,
131 * the `Task` module of the `ti.sysbios.knl` package is used.) In this
132 * example, the `ENTRY` bit is turned on and the `EXIT` bit is turned off.
133 * Both bits are configured to be runtime modifiable.
134 *
135 * @p(code)
136 * var Diags = xdc.useModule('xdc.runtime.Diags');
137 * var Task = xdc.useModule('ti.sysbios.knl.Task');
138 *
139 * Task.common$.diags_ENTRY = Diags.RUNTIME_ON;
140 * Task.common$.diags_EXIT = Diags.RUNTIME_OFF;
141 * @p
142 *
143 * @p(html)
144 *

145 * @p
146 *
147 * Runtime example: The following C code shows how to disable and
148 * reenable `ENTER` diagnostics at runtime for the `ti.sysbios.knl.Task`
149 * module configured in the previous example. The first call to
150 * `{@link Diags#setMask Diag_setMask()}` enables entry diagnostics
151 * (`"+E"`) for just the `ti.sysbios.knl.Task` module; any call to any
152 * `Task` method in the application causes an "entry" `Log` event to be
153 * generated. The second call disables ("-E") the generation of these
154 * events. See `{@link #setMask Diags_setMask()}` for a complete
155 * description of the strings accepted by this function.
156 *
157 * @p(code)
158 * #include <xdc/runtime/Diags.h>
159 * :
160 * Diags_setMask("ti.sysbios.knl.Task+E");
161 * :
162 * Diags_setMask("ti.sysbios.knl.Task-E");
163 * @p
164 *
165 * @p(html)
166 *

167 * @p
168 *
169 * Configuration example: The following XDC configuration statements
170 * turn on asserts in the entire program.
171 *
172 * @p(code)
173 * var Diags = xdc.useModule('xdc.runtime.Diags');
174 * var Defaults = xdc.useModule('xdc.runtime.Defaults');
175 *
176 * Defaults.diags_ASSERT = Diags.ALWAYS_ON;
177 * @p
178 *
179 * @p(html)
180 *

181 * @p
182 *
183 * Configuration example: Using the
184 * `{@link Diags#setMaskMeta Diags.setMaskMeta()}` function, the
185 * following XDC configuration statements turn on asserts in all

207 *
208 * At run-time a module's diagnostics mask is an ordinary data word

210 * corresponding diagnostic is disabled or enabled. At configuration
211 * time, however, each bit of the diagnostics mask can be
212 * placed in one of several `Mode`s; these modes determine its initial
213 * runtime value and whether or not the bit is modifiable at runtime.
214 *
215 * When setting a module's diagnostics mask at configuration time,
216 * use one of the enumerated values of type `Mode`. These
217 * values will either set or clear a bit in the mask and also define
218 * if the bit can be changed at run-time. For example, using
219 * `ALWAYS_OFF` as the bit value means that bit cannot be set
220 * at run-time. This fact can be used by an optimizer to perform

This is still in development. d3 can take a bit of time to render large datasets, so if it take some time between
switching beams, don't be surprised. Camping beams are especially troublesome.
How it works
The web app is run developed using Flask. When you click plot, an AJAX request is sent to the flask app (on thr server), which reads data from the VT server using the DaViTPy read routines. The data is then passed back to the client's browser as an
JSON object. The data is then

Research Internship
PCA: Complementation and Model Checking
Mentored by Prof. Paul Gastin & Benedikt Bollig at LSV, ENS Cachan (May - July 2014)
We study the language-theoretical aspects of parameterized communicating automata (PCAs), in which processes communicate via rendez-vous. A PCA, unlike Communicating Automata, is not dependent on topology and can be run on any topology of bounded degree. We show that, under a context bound, which restricts the local behavior of each process, PCAs are effectively complementable and use it to obtain a mondadic second-order (MSO) logic characterization of PCA. As the emptyness problem for context bounded PCAs is decidable for the class of pipelines, rings, and trees, their model-checking problem wrt. MSO properties also becomes decidable.
Stemming the flow of Information in a Social Network
Research Intern at Adobe Research Labs under the supervision of Dr. Balaji Vasan (May - July 2013)
Due to the volatility of social networks, a negative campaign or a rumor can go viral resulting in severe impact to the community. We aim to solve this problem of stemming the flow of a rumor/negative campaign in a network by observing only parts of the network. Given a negative campaign and information about the status of its spread through a few candidate nodes, our algorithm estimates the information flow in the network and based on this estimated flow, finds a set of nodes which would be instrumental in stemming the information flow. The proposed algorithm is tested on real-world networks and its effectiveness is compared against other existing works.

Logic data validation
Test if malicious data can be injected into application so that app will consider them as validated/secure.
For example in multistage process examine if some parameters are passed in more than in one process. If so,
try to tamper parameters in later stage.
Application/system must ensure that only “logically valid” data is accepted at all input and hand off points of the applica- tion or system and data is not simply trusted once it has entered the system.
Test Ability to forge requests
Test if pages which shouldn't be reached given specific time or circumstances can be reached.
Test for Process Timing
Test if any data or application behaviour can be deduced by request timing measure
Test Number of Times a Function Can be Used Limits
Verify that the application does not allow users to exercise its functions more times than required by the business logic workflow.
Testing for the Circumvention of Work Flows
Test for skipping, repeating or mixing stages in multistep process


VERGE Accelerate (Circular and Carbon): Lingrove
On the VERGE 19 main stage, selected finalists pitch to a live audience of business leaders, government officials and investors, as well as to a global online audience. During this fast-paced pitch competition, industry experts provide commentary and audience votes determine the winner.


For this recipe you will need a heavy, flat baking tray and a 25cm/10in fluted flan tin.
For the pastry, put the flour, icing sugar and cocoa powder into a large bowl and mix them together. Lightly beat the egg with the lemon juice and 2 tablespoons very cold water in a measuring jug with a fork. Set aside.
Add the butter to the flour and toss the cubes to coat them in the flour. Rub the butter into the flour, using your fingertips.  Keep going until the mixture looks like fine breadcrumbs.) Make a well in the centre of the mixture and pour in the egg mixture. Incorporate the liquid into the flour and butter mixture, using one hand. Avoid overworking the dough as this will make your pastry tough. If it is too dry, add a splash more cold water.
When the dough just sticks together in clumps, form it into a ball. Knead it very lightly on a lightly floured surface to bring it together into a smooth dough. Again, don’t overwork it. You can test it by taking a little bit of pastry and rolling it out. If it starts to crack easily, it needs just a touch more kneading to develop the gluten slightly more. Wrap the pastry in cling film and leave it in the fridge to chill for about 30 minutes.
Preheat the oven to 190C/170C Fan/Gas 5. Heat a heavy, flat baking tray.
Roll the pastry out on a floured surface and use it to line a 25cm/10in fluted flan tin. Leave any excess overhanging and prick the base of the pastry using a fork. Chill the pastry for 10 minutes.
Line the pastry case with parchment paper and fill with ceramic baking beans or uncooked rice. Place the tin on the hot baking tray and bake blind for about 15 minutes until set and pale golden-brown. Remove the beans and paper and return to the oven for about 10-12 minutes until the base is cooked. Reduce the oven temperature to 180C/160C Fan/Gas 4.
For the filling, melt the chocolate and the butter together in a heatproof bowl over a pan of simmering water. When melted, set aside to cool slightly.
In a medium saucepan, combine the sugar and golden syrup and bring to the boil, stirring constantly. Set aside to cool.
Beat the eggs in a large bowl, then stir in the chocolate mixture. Whisk in the sugar syrup mixture and thoroughly combine. (It’s important to cool the melted chocolate and sugar syrup or they will scramble the eggs.) Add the vanilla extract and stir in the pecans.
Pour the pecan filling into the baked pastry and bake in the oven for 30-40 minutes until set. Cool and serve with vanilla ice cream or double cream.

For this week’s technical blog, I decided to tackle a subject that I myself needed a lot of training on. I found that through my learning of blocks, procs and lambdas, a lot was cleared up and I would like to share that with you, my reader. Lets start with blocks
Blocks
It can be a little confusing that in a language like Ruby where we are told that everything is an object comes along learning about blocks which ARE NOT OBJECTS!
A block is essentially a block of code in between do and end. Blocks have a special key word “yield” attached to its calling. When we call a block, we are only ever using it in that instance. Blocks cannot be saved or called outside of it function.
Procs
A proc is an anonymous function that can be represented as an object. A proc, short for procedure, is something we explicitly define and can call again later on in the code. Its state is saved. In order for a proc to work, it must also have a block or it will look for a block to attach itself to. The proc object will run whether or not we call an argument.
Lambdas
Lambdas are essentially procs but with slightly different behaviors. Lambdas check for number of arguments, as procs do not. It will act like a method in which you will receive an argument error if they do not equal eachother.
I hope this cleared some information up about blocks, procs and lambdas!


We went to see the circus. The theme song was maddeningly repetitive, but the tightrope walkers made up for it.

If you haven’t visited, the history lessons from Alcatraz (and the US prison system in general) are fascinating. Everyone loves a harrowing escape story.

I happened upon free Carrie Underwood box seats, so I took my wife on a date. Not my favorite music, but the show was amazing entertainment, and Carrie has some serious pipes.
I finally conquered my first multi-pitch climb. This is a shot of my brother scaling the second section.
There’s a large flat spot on Looking Glass Rock that climbers call the “Parking Lot.” It makes for a great rest halfway up.

About Vaccines
There are now several vaccines that are in use. The first mass vaccination programme started in early December 2020 and the number of vaccination doses administered is updated on a daily basis here. At least 13 different vaccines (across 4 platforms) have been administered.
Once vaccines are demonstrated to be safe and efficacious, they must be authorized by national regulators, manufactured to exacting standards, and distributed. WHO is working with partners around the world to help coordinate key steps in this process, including to facilitate
equitable access to safe and effective COVID-19
vaccines for the billions of people who will need them.
FAQS related to Vaccines
Which is the most effective Covid-19 vaccine?
Pfizer-BioNTech, Moderna, and Oxford-AstraZeneca have all announced that their vaccine candidates are effective in protecting against COVID-19.
Bahrain, the UK, Canada, the US, and Mexico have already approved the use of the Pfizer vaccine in their countries, and
the Moderna vaccine seems sure to soon follow suit. India has so far given more than 260 million doses of three approved vaccines -
Covishield, Covaxin and Sputnik V. It also gave approval to Indian pharma company Cipla to import the Moderna vaccine,
which has shown nearly 95% efficacy against Covid-19.
Can I have the second dose with a different vaccine than the first dose?
Clinical trials in some countries are looking at whether you can have a first dose from one vaccine and a second dose from a different vaccine. There isn't enough data yet to recommend this type of combination.
Is the vaccine safe for children?
Vaccines are usually tested in adults first, and only later assessed in children when safety has been proven in adults, because children are still developing and growing. COVID-19 has also been a more serious and dangerous disease among older people. Now that the vaccines have been determined to be safe for adults, they are being studied in children.
Children aged between 12 and 15 who are at higher risk of severe COVID-19 may be offered this vaccine alongside other priority groups for vaccination.
While the supply of vaccines is limited, the ongoing priority is to vaccinate those most at risk of serious illness who still have not been vaccinated in many parts of the world: older people, those with chronic health conditions, and health workers. Most children are at low risk of serious disease and vaccinating them is primarily about reducing transmission, which can also be achieved through public health measures, including: physically distancing from others, cleaning hands frequently, sneezing and coughing into their elbow, wearing a mask if age appropriate and avoiding crowded, poorly ventilated spaces.
Do the vaccines protect against variants?
More studies are needed to assess the effectiveness of the current COVID vaccines against the variants. A growing body of data suggests that most vaccines stimulate enough immunity to retain substantial efficacy against most variants, especially for severe disease, hospitalization, and death. The impact of the variants on
efficacy against mild disease and against infection without disease is more impacted than for the more severe outcomes.
The reason vaccines substantially retain protection against disease is likely related to the broad immune response they induce, which means that virus changes or mutations are unlikely to make vaccines completely ineffective. If any of these vaccines become less effective against one or more variants, it will likely be possible to change the composition of the vaccines to protect against these variants, however this will take time and additional data to fully evaluate. Data continues to be collected and analysed on new variants of the COVID-19 virus.

In an effort to make the most use of my time studying at SIngapore Polytechnic (SP), I intend to make of the schools vast resources and knowledge to take up and complete projects so as to get a more rounded and wole education in the field of engineering. This site will be used to keep track of the progress of said education.


In the period of this two year degree, I developed various skills through academic as well as independent studies. The project-based course syllabus and assignments not only promoted an understanding of the respective subjects but also helped to understand real-life implementations of the concepts.
The four year degree introduced me to the basics of electronics engineering which helped to develop an understanding of hardware-software interactions. In the final year project in this degree gave me an opportunity to demonstrate the skills developed so far.
