A standardized protocol to manage, monitor, update, and control
connected devices, IoT endpoints, user services and home
networks
See https://usp.technology for the current USP
specification.
What is USP?
The User Services Platform is a standardized
protocol for managing, monitoring, upgrading, and controlling
connected devices. USP allows service providers, consumer
electronics manufacturers, and end users to:
- Create interoperable and vendor-independent managed Wi-Fi
systems.
- Perform lifecycle management of consumer connected
devices and containerized microservices.
- Support independent applications for
application-enabled services gateways.
- Enable IoT and consumer electronics upgradability
for critical security patches.
- Develop applications that gather the telemetry necessary to
mass data processing, AI, and machine learning.
- Bootstrap and configure newly installed or
purchased devices and applications.
- Let customer support monitor and troubleshoot
connected devices, services, and home network links.
- Easily map the home network to control service quality and
monitor threats.
- Securely control IoT, smart home, and smart networking
functions locally or from the Cloud.
- Enable multi-tenant (i.e., multi-stakeholder)
management and control.
USP represents the natural evolution of the Broadband Forum’s CPE WAN Management Protocol
(CWMP), commonly known as TR-069. It uses an expanded version of the
Device:2 Data Model to represent device operations (firmware upgrades,
reboots, etc.), network interfaces, and service functions (IoT
functions, VoIP, etc.).


logtalk_tester - Logtalk script for automating running unit tests
logtalk_tester -v
logtalk_tester [-p prolog ] [-m mode ] [-f format ] [-d results ] [-t timeout ] [-s prefix ] [-c report ] [-l level ] [-g goal ] [-- arguments ]
logtalk_tester -h
logtalk_tester is a script for automating running Logtalk unit tests. This script runs unit tests found on the current directory and recursively in its sub-directories by scanning for tester.lgt and tester.logtalk source files. The script returns a non-zero exit status in case of failed tests or test set errors. When a tester.sh file exists in the current directory, the file is sourced before running the tests. The tester.sh file is sourced with all the parameters passed to the logtalk_tester script.
-v Print script version.
-p Back-end Prolog compiler. Default is SWI-Prolog. The following identifiers are used: B-Prolog - b, CxProlog - cx, ECLiPSe - eclipse, GNU Prolog - gnu, JIProlog - ji, Lean Prolog - lean, Qu-Prolog - qp, SICStus Prolog - sicstus, SWI-Prolog - swi, SWI-Prolog with Logtalk pack - swipack, XSB - xsb, XSB-MT - xsbmt, YAP - yap.
-m Compilation mode. Default is normal. Valid values are optimal, normal, debug, and all.
-f Format for writing the test results. Default is default. Valid values are default, tap, and xunit.
-d Directory to store the test results. Default is the local ./logtalk_tester_logs directory.
-t Timeout in seconds for running each test set. Default is 0; i.e. disabled.
-s Path prefix to suppress when printing test suite and test result paths. Default is the user home directory.
-c Code coverage report. Default is none. Valid values are xml and none.
-l Directory depth level to look for test sets. Level 1 means current directory only. Default is to recurse into all sub-directories.
-g Initialization goal. Default is true.
-- Arguments to be passed to the integration script used to run the tests (no default).
-h Provide help on script usage.
0 All non-skipped tests pass and there are no broken, timed out, or crashed test sets.
1 Some tests fail but there are no broken, timed out, or crashed test sets.
3 One or more test sets timed out while executing but there are no broken or crashed test sets.
5 One or more test sets are broken and thus could not be executed but there are no crashed test sets.
7 One or more test sets crashed the process running them.
9 The sourced tester.sh file returned a non-zero code.
LOGTALKHOME Specifies the location of the Logtalk installation.
LOGTALKUSER Specifies the location of the Logtalk user directory.
$LOGTALKUSER/library/tester_versions.lgt Logtalk source file used for printing the Logtalk and backend Prolog compiler versions.

PKCS11\&.CONF
Section: System Files (5)Updated:
Index Return to Main Contents
NAME
pkcs11.conf - Configuration files for PKCS#11 modulesDESCRIPTION
The pkcs11.conf configuration files are a standard way to configure PKCS#11 modules.
FILE FORMAT
A complete configuration consists of several files. These files are text files. Since p11-kit is built to be used in all sorts of environments and at very low levels of the software stack, we cannot make use of high level configuration APIs that you may find on a modern desktop.
Each setting in the config file is specified consists of a name and a value. The name is a simple string consisting of characters and dashes. The name consists of alpha numeric characters, dot, hyphen and underscore.
The value is specified after the name on the same line, separated from it by a : (colon). White space between the name and value is ignored.
Blank lines are ignored. White space at the beginning or end of lines is stripped. Lines that begin with a # character are ignored as comments. Comments are not recognized when they come after a value on a line.
A fictitious module configuration file might look like:
-
module: module.so # Here is a comment managed: true setting.2: A long value with text. x-custom : text
MODULE CONFIGURATION
Each configured PKCS#11 module has its own config file. These files can be placed in various locations.
The filename of the configuration file may consist of upper and lowercase letters underscore, comma, dash and dots. The first characters needs to be an alphanumeric, the filename should end with a .module extension.
Most importantly each config file specifies the path of the PKCS#11 module to load. A module config file has the following fields:
module:
-
The filename of the PKCS#11 module to load. This should include an extension like
.so
If this value is blank, then the module will be ignored. This can be used in the user configs to override loading of a module specified in the system configuration.
If this is a relative path, then the module will be loaded from the default module directory.
critical:
-
Set to
yes
if the module is critical and required to load. If a critical module fails to load or initialize, then the loading process for all registered modules will abort and return an error code.
This argument is optional and defaults to no.
enable-in:
-
A comma and/or space separated list of names of programs that this module should only be loaded in. The module will not be loaded for other programs using p11-kit. The base name of the process executable should be used here, for example
seahorse, ssh.
This is not a security feature. The argument is optional. If not present, then any process will load the module.
disable-in:
-
A comma and/or space separated list of names of programs that this module should not be loaded in. The module will be loaded for any other programs using p11-kit. The base name of the process executable should be used here, for example
firefox, thunderbird-bin.
This is not a security feature. The argument is optional. If not present, then any process will load the module.
priority:
-
The value should be an integer. When lists of modules are returned to a caller of p11-kit, modules with a higher number are sorted first. When applications search modules for for certificates, keys and trust policy information, this setting will affect what find first.
This argument is optional, and defaults to zero. Modules with the same priority option will be sorted alphabetically.
trust-policy:
- Set to yes to use use this module as a source of trust policy information such as certificate anchors and black lists.
Do not specify both enable-in and disable-in for the same module.
Other fields may be present, but it is recommended that field names that are not specified in this document start with a x- prefix.
GLOBAL CONFIGURATION
A global configuration may also be present. This file contains settings that are not related to a single PKCS#11 module. The location(s) of the global configuration are described below. The global configuration file can contain the following fields:
user-config:
- This will be equal to one of the following values: none, merge, only.
Other fields may be present, but it is recommended that field names that are not specified in this document start with a x- prefix.
CONFIGURATION FILES
Each configured PKCS#11 module is has its own config file. These files are placed in a directory. In addition a global config file exists. There is a system configuration consisting of the various module config files and a file for global configuration. Optionally each user can provide additional configuration or override the system configuration.
The system global configuration file is usually in /etc/pkcs11/pkcs11.conf and the user global configuration file is in /data/.pkcs11/pkcs11.conf in the user's home directory.
The module config files are usually located in the /etc/pkcs11/modules directory, with one configuration file per module. In addition the /data/.pkcs11/modules directory can be used for modules installed by the user.
Note that user configuration files are not loaded from the home directory if running inside a setuid or setgid program.
The default system config file and module directory can be changed when building p11-kit. Always lookup these paths using pkg-config.

Hey I'm 15 years old and I've had some messed up reoccurring experiences with marijuana. I have tried salvia several times, but I've never witnessed any paranormal things happening in real life. The first time I tried salvia was about 3 months ago with some buddies and I've done it about 5 or 6 times all in one week. I smoke weed for fun with my friends just about every week but recently (starting about a month ago) I've been 'living' my dreams. Any night that I fall asleep high I have wild dreams that I never remember about the next day, which is pretty normal. The screwed up part is that the next time I'm high I go into like a weird dream world that is actually the dream I had the last time I was asleep high.
I tried looking up if smoking weed had anything to do with being able to predict the future in your dreams but the only thing that was related to that was salvia and deja vu. This has happened about 10 times or so over the past month and each time I get high, I experience more an more things about the most recent dream I had. The last time I smoked (about 3 days ago) I could predict everything that was about to happen in perfect detail about 10 seconds before they actually took place. That very moment I also realized that my dreams get more realistic each time. Has anyone else had this happen to them? I'm curious to find out if it might have to do with all of that salvia I smoked a couple months ago.

Popular modern day languages have progressed from predominantly procedural/imperative to single dispatch object oriented. Most mainstream languages also incorporate functional and generic programming to a limited extent as well. We will worry only about the most common subset of features for this article.
The most common methods of dealing with multiple dispatch using these features will be shown. These have been discovered through my own research and experience. Read through this with a critical mind, and be sure to diversify your sources on this topic. The criticism sections following each approach will be the author's opinion, not actual facts.
This entry will utilize two languages with which most programmers will have at least a passing familiarity: C and Java.
Each of these techniques are fundamentally different. While in many cases they are interchangable, there are instances where they are not. For example, table based solutions allow the branching logic to be modified at runtime, while switch and object based solutions do not inherently support this.
I have included source code to demonstrate each of these approaches. Code is provided in C or Java, depending on the features needed for each technique. The article is written without referencing the code directly to allow both the code and article to exist independently.
What is Multiple Dispatch?
Code is often written against abstractions. Abstractions are helpful in the development process, but they all must eventually be resolved to a concrete type in order to do actual work.
A Single Dispatch Example
As an example from an object oriented language, an Animal
abstraction may provide a speak
method. A programmer may write
If an Animal is a purely abstract object, then its speak
method will have no actual code. At runtime, the program will dynamically dispatch to object's underlying type and call that object's speak
method. If the abstract animal
object points to an instance of Dog
class, then the above call may print woof
to the screen. The above call might effectively be translated to
dog.speak(); // prints "woof"
A Multiple Dispatch Example
At times it my be necessary to dispatch based on multiple types.
A programmer writing a game of rock-paper-scissors might use an abstraction of Attacker
to represent a potential move. When the actual game is played the type of both attackers will need to be known. What we want to write is something along the lines of:
(attacker1 and attacker2).determineWinner();
attacker1
might be resolved to Rock
and attacker2
might be resolved to Scissors
. In this case, the code relating to rock beating scissors would be called.
Multiple Dispatch in C
There are two main ways to go about this in C. Both of these involve defining types which explicitly describe themselves. An enum may be defined as
enum { ROCK, PAPER, SCISSORS} attacker;
The types for each attack could be defined by
struct { attacker TYPE = ROCK; }
struct { attacker TYPE = PAPER; }
struct { attacker TYPE = SCISSORS; }
Big Switch Statement
The typically cringeworthy solution is to have a Big Switch Statement to handle every possible combination. In psuedocode, for sanity related reasons
switch attacker1.TYPE:
case ROCK:
switch attacker2.TYPE:
case ROCK: tie
case PAPER: lose
case SCISSORS: win
case PAPER:
switch attacker2.TYPE:
case ROCK: win
etc...
etc...
This switch statement ends up being huge with only three types, and the complexity grows exponentially as types are added.
Beyond factoring each switch and/or case statement into its own function, the switch statement itself may be replaced with a jump table.
Criticisms
Good
- Not too difficult to manually trace through
Bad
- Adding/removing types requires a lot of work which won't be verified by a compiler
- Have to add a type field to all types and keep up with these
- Switch statements tend to poliferate
The first bullet under the negative criticisms is particularly important. Adding or removing types involves modifying a lot of code spread out all over your program, and the compiler will not let you know if you have left anything out in many cases.
Big Jump Table
The logic of a switch statement or chain of if/else statements based on explicitly defined types may be replaced by a jump table. Imagine a matrix of possible outcomes for the game itself
| - |
Rock |
Paper |
Scissors |
| Rock |
Tie |
Lose |
Win |
| Paper |
Win |
Tie |
Lose |
| Scissors |
Lose |
Win |
Tie |
We can translate this into code by creating functions for every possible combination of rock-paper-scissors, then populating a table based on the intersection of the types. Dispatching to the correct function can then be done by looking up the function pointer in the table
BattleFunction generate_outcome = gameMatrix[attacker1.TYPE, attacker2.TYPE];
generate_outcome();
Maintaining the TYPE
field in all of our objects is still a bit of a pain. If we were to add or remove any types, we would have to edit our enum and update our matrix.
Criticisms
Good
- Tables can be constructed outside of static code. This consolidation makes modification easier and will usually not even require modification of the code itself.
- Leads to simpler code. Functions which would typically contain large switch statements simply index into a table.
Bad
- Much more difficult to debug/trace.
- Still requires types to label themselves.
Again, the first bullet above is worth reading over again.
Introspection
Introspection may be used to help alleviate some of the issues with the C-based approaches to this problem when applicable.
Instead of manually tracking each type, the underlying type of each abstraction is determined via a language's introspection features, and then the relevant code is dispatched to based on the findings.
As a side note, this approach is often times discovered independently and immediatelly touted as a panacea for the ugly switch/table based methods previously described, and the also ugly object-based double indirection used in object oriented languages (described in a moment). It is my opinion that it is not. While it does simplify some aspects of the table-based approach, it still carries many of the drawbacks associated with that method, and it introduces many of its own drawbacks in the process. These will be detailed in the general compare/contrast of each method toward the end.
Criticisms
Good
- Removes the need for types to keep track of themselves.
Bad
- Makes debugging/tracing even more painful.
- While explicit tracking of types is removed, the developer must still be mentally aware of what these types are when updating tables.
Object Oriented Approach
In object oriented languages, polymorphism is the go-to mechanism for replacing branches based on type. To implement double dispatch, one can first write something along the lines of
attacker1.handle(attacker2);
This dispatches to the appropriate handle
method based on attacker1's type. If attacker1
is a rock
, for example, you could mentally translate this to
Once we're in the Rock's handle
method, we know we are a rock. Now all that's left to do is figure out what attacker2 is. We can do this in similar fasion inside of the rock.handle method
attacker2.handleRock(this);
We know that we're a rock
, so this
is really rock
. Again, if attacker2
is actually paper
, the call may be mentally translated to
And in our Paper class, the handleRock method can contain the code which handles the rock versus paper interaction. Function overloading is often used during this second dispatch, but it is not necessary for the language to support overloading for this technique to work.
Criticisms
Good
- Returns many of the potential errors to compile time
- Avoids the poliferation inherent in switch-based solutions
Bad
- Can seem convoluted to the uninitiated
- It is an object oriented solution which violates many object oriented ideas
- Costs associated with adding/removing types vary based on which set of types you are modifying
I will spend the second half of this article examining this object oriented approach, as I find it to be heavily criticized in ways which I think are unfair. If the above bullets are not clear, feel free to read on.
Common Object Oriented-based Complaints
Hopefully it is now clear that there are no clear winners when it comes to emulating multiple dispatch. Many would have you believe, however, that the object oriented solution is a clear loser. While it is by no means perfect, I feel many complaints are exaggerated or meaningless.
Though it will be discussed why later, many of the complains about the Visitor pattern will be addressed here as well.
It Breaks Encapsulation
This argument is absolutely true.
Object oriented programmer is centered around the idea that a set of data and the functions which operate on it should be packaged together. The public interface of the object protects the data from change which might put the object into an invalid state.
When we use multiple dispatch, though, we call a function which is supposed to interact with more than one type. In other words, the function itself does not belong to any one object--rather it belongs to both objects. Since the language does not inherently support multiple dispatch, there is usually no facility to create a function which is somehow owned by multiple objects.
I really have no counter argument here, but it is important to note that none of the other methods are any better in this respect. While the object oriented approach leverages the mechanics of objects, this does not mean that the author is attempting to shoe-horn the dispatch function into the object oriented paradigm.
You Don't Need It
The idea here is that if you're attempting to implement multiple dispatch, there is going to be some other way which is simpler/better that you just aren't using. This is a particularly common complain when discussing the Visitor pattern (discussed later).
The problem with this complaint is that it is just wrong. Situations which require multiple dispatch really do require multiple dispatch.
Most of these complaints stem from improper the abuse of the Visitor pattern. Be very wary when reading about these--just because a person has improperly picked a pattern, and then that person later on finds a better way of solving their problem, does not mean that the initial solution is A Bad Thing that should never be used.
The Dispatch Functions Grow Combinatorially
This one is another complaint that's absolutely correct. What drives me nuts is that it is a complaint!
Consider our rock-paper-scissors game. Without going into the math behind it (though it is very simple), you can see from our matrix that there are three possible ways to attack, for a total of nine possible game-handling function calls. If we were to add another way to attack, we would have sixteen functions to write.
In more complex games, such as any that you might find on the shelf in a store, there may be 20 or more potential entities to consider. For 20 entities, that's up to four hundred collision handling functions.
Needless to say, I can see why people freak out about this exponential growth in the number of necessary functions. Unfortunately, that's life, deal with it. If you have a game with 20 entities flying around, you just have to deal with them colliding. There's no real way around it.
Table-based methods have the advantage that not all cells need to be populated, but this just takes us back to the initial trade-off--an object-based design would require 400explicit function definitions, while a table based method would only require the ones that will actually ever be called (but you better hope you don't accidentally try to collide two objects that don't have a handler).
I am not claiming that either approach is superior to the other, but the number of situations you need to mentally handle will grow expontentially whether you like it or not.
Open/Closed Concerns
This one is actually tricky, legitimate, and will force me to finally bridge the gap between the general case of multiple dispatch and the Visitor pattern.
The rock-paper-scissors example is a special case. In this instance, we are dispatching to two different types, each from the same group of types. In other words, a rock, paper, or scissors will always be up against a rock, paper, or scissors. Adding or removing a possible attack is going to cause a lot of code to shift around. Having to chance code in classes that deal with rock/paper/scissor attacks everytime a new attack is added or removed actually makes sense, and there probably are not many people that would complain about having to do this.
The types dispatched to do not always have to be from the same group, though. A common example is that you have a group of heterogeneous types (with a common interface), and you want some way to render these. In this case, we have two seperate groups of types which we want to dispatch to.
The usual example for this is some sort of drawing program. For example
Shapes
Circle
Square
* Line
Renderers
Win32
GTK
* ASCII
A Renderer
would have methods which render each type of Shape
, and each Shape
would simply provide the secondary dispatch function (renderer.visit(this)
).
The complaint is this: adding/removing a Renderer
is insanely easy, but adding/removing a Shape
is insanely difficult. Adding/removing a Renderer
is as simple as adding or removing the class from the project. Adding/removing a Shape
requires that every Renderer object be modified.
My guess is that this asymmetry is where a lot of the convoluted definitions and flawed understandings originate. It is my opinion that if multiple dispatch is being used correctly, then the need to modify so many classes is ultimately justified. In the classic Shape/Renderer example above, you would want to modify all of your renderers when a shape is added/removed.


The release of JDK 8 introduced Java Mission Control, Java Flight Recorder, and jcmd
utility for diagnosing problems with JVM and Java applications. It is suggested to use the latest utility, jcmd
instead of the previous jstack
utility for enhanced diagnostics and reduced performance overhead.
The following sections describe troubleshooting techniques with jstack
utility.
The jstack
command-line utility attaches to the specified process or core file and prints the stack traces of all threads that are attached to the virtual machine, including Java threads and VM internal threads, and optionally native stack frames. The utility also performs deadlock detection.
The utility can also use the jsadebugd
daemon to query a process or core file on a remote machine. Note: The output takes longer to print in this case.
A stack trace of all threads can be useful in diagnosing a number of issues, such as deadlocks or hangs.
The -l
option, which instructs the utility to look for ownable synchronizers in the heap and print information about java.util.concurrent.locks
. Without this option, the thread dump includes information only on monitors.
The output from the jstack
pid option is the same as that obtained by pressing Ctrl+\ at the application console (standard input) or by sending the process a QUIT signal. See Control+Break Handler for an output example.
Thread dumps can also be obtained programmatically using the Thread.getAllStackTraces
method, or in the debugger using the debugger option to print all thread stacks (the where
command in the case of the jdb
sample debugger).
For more details on the jstack
utility, see the jstack
command man page.
If the jstack
pid command does not respond because of a hung process, then the -F
option can be used (on Oracle Solaris and Linux operating systems only) to force a stack dump, as shown in Example 2-29.

To obtain stack traces from a core dump, execute the jstack
command on a core file, as shown in Example 2-30.
The jstack
utility can also be used to print a mixed stack; that is, it can print native stack frames in addition to the Java stack. Native frames are the C/C++ frames associated with VM code and JNI/native code.
To print a mixed stack, use the -m
option, as shown in Example 2-31.

Frames that are prefixed with an asterisk (*) are Java frames, whereas frames that are not prefixed with an asterisk are native C/C++ frames.
The output of the utility can be piped through c++filt
to demangle C++ mangled symbol names. Because the Java HotSpot VM is developed in the C++ language, the jstack
utility prints C++ mangled symbol names for the Java HotSpot internal functions.
The c++filt
utility is delivered with the native C++ compiler suite: SUNWspro
on Oracle Solaris operating system and gnu
on Linux.

In Athens, students are big on shopping locally, and we take great pride in supporting our favorite businesses. Sometimes, it can be hard for us to even imagine a hot cup of coffee that isn’t from our beloved Donkey, Brenen’s or Court Street Coffee.
The Toledo Farmers’ Market introduced me to businesses and people who would emit many of the same feelings. The people shopping alongside the range of products being sold was an important environment to take in. Farmers’ Markets have certainly come a long way from selling strictly produce, and they serve as an important experience while standing as a great way to support small business.
At the Toledo Farmers’ Market, there was incredible local coffee. A hot cup from Flying Rhino Coffee was exactly what I needed to kick my experience into gear. There were baker vendors scattered throughout the market, all offering a mixture of choices. Holey Toledough, Toledo’s whimsical donut hub, had a food truck set up and was thick with customers. All Crumbs Artisan Bakery was set up next to Flying Rhino and served incredible goods like Croissant Pretzels and Everything Bagel Bread.
Lots of booths were selling handmade jewelry and other one of a kind pieces. To name just a few of the vendors: CANDE, Dado Jewelry and Willow Moon Botanicals. All of the pieces and products were enticing, and the people were friendly and warm. Supporting their businesses was easy and it felt good. The market provided a great outlet for doing so.
Everyone at the market seemed to be enjoying themselves. As cheesy as it may seem, you can tell when someone is smiling under their mask. It was easy to spot the regulars against the newbies, like my dad and myself, yet the entire environment radiated a sense of welcoming.
Wherever it is that you find yourself at this moment, if you are able to, take a trip to your local farmers’ market. It is an experience like no other, and supporting small businesses is not only always easy, but especially at this time, is an important and rewarding thing to do.

Somebody just told you about a vulnerability in your code. Moreover, they published a paper about it. Even worse, people have been very vocal about it.
What can you do now? The usual (and natural) reaction is to downplay the vulnerability, and try to keep it confidential. After all, publishing a vuln will make your users unsafe, and it is bad publicity for your project, right?
WRONG!
The best course of action is to communicate a lot. Here's why:
Communicate with the security researcher
Yes, I know, we security people tend to be harsh, quickly flagging a vulnerable project as "broken", "dangerous for your customers" or even "EPIC FAIL". That is, unfortunately, part of the folklore. But behind that, security researchers are often happy to help you fix the problem, so take advantage of that!
If you try to silence the researcher, you will not get any more bug reports, but your software will still be vulnerable. Worse, someone else will undoubtedly find the vulnerability, and may sell it to governments and/or criminals.
Vulnerabilities are inevitable, like bugs. Even if you're very careful, people will still find ways to break your software. Be humble and accept them, they're one of the costs of writing software. The only thing that should be on your mind when you receive a security report is protecting your users. The rest is just ego and fear of failure.
So, be open, talk to security researchers, and make it easy for them to contact you (tips: create a page dedicated to security on your website, and provide a specific email for that).
Damage control of a public vulnerability
What do you do when you discover the weakness on the news/twitter/whatever?
Communicate. Now.
Contact the researchers, contact the journalists writing about it, the users whining about the issue, write on your blog, on twitter, on facebook, on IRC, and tell them this: "we know about the issue, we're looking into it, we're doing everything we can to fix it, and we'll update you as soon as it's fixed".
This will buy you a few hours or days to fix the issue. You can't say anything else, because you probably don't know enough about the problem to formulate the right opinion. What you should not say:
- "we've seen no report of this exploited in the wild", yet
- "as far as we know, the bug is not exploitable", but soon it will be
- "the issue happens on a test server, not in production" = "we assume that the researcher didn't also test on prod servers"
- "no worries, there's a warning on our website telling that it's beta software". Beta means people are using it.
Anything you could say in the few days you got might harm your project. Take it as an opportunity to cool your head, work on the vulnerability, test regressions, find other mitigations, and plan the new release.
 You have to tell your users about it. As time passes, more and more people will learn about the issue, so they might as well get it from you.
You should have a specific webpage for security issues. You may fear that criminals might use it to attack your software or website. Don't worry, they don't need it, they have other ways to know about software weaknesses. This webpage is for your users. It has multiple purposes:
- showing that you handle security issues
- telling which versions someone should not use
- explaining how to fix some vulnerabilities if people cannot update
For each vulnerability, here is what you should display:
- the title (probably chosen by the researcher)
- the security researcher's name
- the CVE identifier
- the chain of events:
- day of report
- dates of back and forth emails with the researcher
- day of fix
- day of release (for software)
- day of deploy (for web apps)
- the affected versions (for software, not web apps)
- the affected components (maybe the issue only concerns specific parts of a library)
- how it can be exploited. You don't need to get into the details of the exploit.
- The target of the exploit. Be very exhaustive about the consequences. Does the attacker get access to my contacts list? Can he run code on my computer? etc.
- The mitigations. Telling to update to the latest version is not enough. Some users will not update right away, because they have their own constraints. Maybe they have a huge user base and can't update quickly. Maybe they rely on an old feature removed in the latest version. Maybe their users refuse to update because it could introduce regressions. What you should tell:
- which version is safe (new versions with the fix, but also old versions if the issue was introduced recently)
- if it's open source, which commit introduced the fix. That way, people managing their own internal versions of software can fix it quickly
- how to fix the issue without updating (example for a recent Skype bug). You can provide a quick fix, that will buy time for sysadmins and downstream developers to test, fix and deploy the new version.
Now that you have a good security report, contact again the security researchers, journalists and users, provide them with the report, and emphasize what users risked, and how they can fix it. You can now comment publicly about the issue, make a blog post, send emails to your users to tell them how much you worked to protect them. And don't forget the consecrated formule: "we take security very seriously and have taken measures to prevent this issue from happening ever again".
Do you need help fixing your vulnerabilities? Feel free to contact me!

GrDrawPath(), GrFillPath()
GrDrawPath()
draws a path using the current line attributes.
GrFillPath()
fills a path using the current area attributes.
GrFillPath()
can fill the path using either an odd/even or winding fill rule. If the path is to be filled using the winding fill rule, the path must have been defined so that the segments forming the border of each region go around the region so that the interior of the region is to the left. That is, on convex parts of the border, edges should be in the counterclockwise direction. On concave parts of the border edges should go clockwise. For an illustration of a path following this rule, see the figure above. The fill rule is specified by means of a
RegionFillRule
value, which may be one of
ODD_EVEN or
WINDING.
When you define a path by combining two other paths, the result might not be exactly what you would expect.

After reading some articles on herbal-E, I've decided to conduct some experiments with it. I've used 200mgr of Ephedrine in pills and two pills of a dietary supplement called 'Brain Booster', which contained Gingko Biloba, Siberian Ginseng, Gotu Kola and Bee Polen. It worked quite allright, but that's not the issue. Some time later at night, me and friend have got 2 grams of dried shrooms, which I must say were very potent, because the other day I've consumed 1gr and was triping for 7 hours just 20 minutes past after eating.
So, we ate the shrooms and went to a park. We were hanging around over there for 3 hours or so with no noticeble mushroom effect. Then in deep sorrow I went home to have some sleep. After approximatly 1 hour of sleep, I woke and realized that my room is full of hallucinations, but the feeling was that the trip will soon end. So I went back to sleep. In other words, our shroom session sucked. And the cause of it was most probably the mixture of herbs, because we did not use anything out of ordinary that day except for herbal-E. Beware of this, and have a nice trip!

3. Inclusivity Bugs
“Inclusivity Bug” term borrowed from Anita Sarma and GenderMag, to describe those unknown barriers and obstacles diverse participants experience using software, that might be otherwise invisible to the majority demographic. The cohort will not work on these bugs, but should be aware of the research driving this project.
We’ve started using this to describe the obstacles underrepresented contributors face while attempting to make a first contribution. We’re starting to get better at creating simple ways projects can evaluate their projects for inclusive design - like this ‘inclusive governance checklist’.
For the Devtools/Debugger project we invested in six, short (1.5 hrs) contribution sessions with volunteer contributors of diverse backgrounds from a gender, and regional perspectives. What we uncovered can be found in the reading below.
Our call to action, is to establish a standard for the new Inclusion Tag and to use the findings in the document listed below to do that for all non-leadership bugs. We’ll tackle leadership findings separately.
Don’t worry we’ll walk through this in our cohort time :)

2.1 Specs table
Set parameters for the data query to the desired values in this table. These include:
- Start date: insert start date for the query here in the following format: dd/mm/yyyy.
- End date: insert end date for the query here in the following format: dd/mm/yyyy. If omitted, defaults to the current system date.
- Frequency: select the frequency at which you want the data to be queried. Accepted values are “d” (daily), “w” (weekly), “m” (monthly), “y” (yearly).
- Currency: insert the desired currency for the query. If omitted, defaults to the default currency for the security as specified in Bloomberg.


Quantized inertia predicts the rotation of disc galaxies simply, without dark matter and without adjustment. (McCulloch, 2012, 2017).
QI also predicts a change in galactic behaviour into the past, not predicted by any other theory which seems to be borne out by recent data (McCulloch, 2017).
The orbits of wide binaries, stars far apart that are apparently bound gravitationally but should not be, are predicted by QI (McCulloch and Lucio, 2019). Dark matter cannot be applied to these systems and MoND does not predict them.
Quantized inertia predicts that energy focused into small asymmetric or symmetric cavities can produce propellant-less thrust (McCulloch, 2018). Six labs have tested this. So far, five have shown some thrust (Perez-Diaz et al., 2021; one has not (Neunzig et al., 2021).
Spacecraft flying by the Earth for gravitational assists have shown anomalous boosts in speed. QI predicts these (McCulloch, 2008) though later flybys showed no anomaly.


To resume a model build in the graphical user interface
1 If the model build is interrupted because of an error, investigate the error and correct it.
2 From the Model Build Information panel, do one of the following:
• To resume the model build process from the point of interruption, click Resume.
• To resume the model build process from a specific model build stage, click the check mark next to Resume and select an option:
• Analysis resumes at the beginning of the analysis stage, reusing information about files and flags.
• Parsing resumes at the beginning of the parse stage, reusing files, flags, and dependency information.
• Updating resumes at the beginning of the update stage, reusing files and all the information extracted from the source code.
• Finalizing resumes at the beginning of the finalize stage, reusing the complete organized information model.
The model resumes building.


equal()
method with just one argument.
Normally, this is a typo of equals()
.
Example:
class Main { public boolean equal(Object obj) { return true; } }
After the quick-fix is applied:
class Main { public boolean equals(Object obj) { return true; } }

Threads can be complicated beasts until you get used to them. They are certainly useful, but at the same
time, they can add a lot of complexity. I have seen several
attemps to provide the ultimate thread wrapper class for Win32, including
MFC's CWinThread and several others on C/C++ Users Journal, to name a
few.
However, I've never been to keen on any of them. I always thought
there had to be a better way. In December 1999, Allen Broadman and Eric
Shaw published an article on CUJ called "Executing a Class Member in
its own thread" that provided a particular solution to the problem. It was very
elegant in some respects and provided much welcome type safety and a lot of
flexibility: It allowed you to create a thread and call any function on any
object instance you wanted, provided the function had a certain signature.
They really had the right idea, but approached it the wrong way.
While it was good and useful, it was unsuitable for any but the most basic use
of threads. The particular problems they had were:
So I took their idea and implemented it in a way that fixed both
of the problems above. It was rather simple: All you had to do was avoid having
the function's signature as a template parameter! This doesn't reduce type
safety at all because even in Broadman's and Shaw's implementation the
function's signature was known, and could simply be deduced from the object's
type.
Some time after writing this, I decided to rethink the approach I
had, which encapsulated everything in a single class, and instead try something
similar to what Broadman and Shaw had, which was to have a special stand-alone
thread creation function that provided automatic type discovery. This meant
splitting the Thread implementation in three different parts:
Thread
class, which wraps a thread HANDLE and ID, but doesResumeThread()
. It also has correctly defined copy constructor andDuplicateHandle()
internally.Yet another advantage of my implementation is that the class
template allows you to provide a thread creation class, so you can plug in your
custom creation function. I supply two classes:
Win32Threader
, which simply calls theCreateThread()
Win32 api.CrtThreader
, which can be used with VC++ C Runtime library,_beginthread()
.To run threads, you can use one of the two RunOnThread()
functions
provided. The first template argument in each one is the type of the Creator class to use, and has
to be provided explicitly at call time (see example below).
The difference between the two functions is that one is for starting threads on
member functions, while the second overload is able to start threads on global standalone functions, or
static member functions. This is done through the use of an adapter class, called GlobalAdaptor.
Using the template is pretty simple, here's an example:
class ThreadedObj {
public:
DWORD some(int a) {
printf ( "In thread: %d\n", a );
return 0;
}
};
DWORD StandAlone ( int b )
{
printf ( "In thread: %d - %d\n", GetCurrentThreadId(), b );
return 0;
}
using namespace Winterdom::Runtime::Threading;
ThreadedObj obj;
Thread thread = RunOnThread<Win32Threader>(obj, &ThreadedObj::some, 8);
// or something like this for a standalone function
// Thread thread = RunOnThread(StandAlone, 8);
thread.WaitOn();
