Hackers have flooded the Internet with virus-tainted spam that targets Facebook's estimated 400 million users in an effort to steal banking passwords and gather other sensitive information.The emails tell recipients that the passwords on their Facebook accounts have been reset, urging them to click on an attachment to obtain new login credentials, according to anti-virus software maker McAfee Inc. If the attachment is opened, it downloads several types of malicious software, including a program that steals passwords, McAfee said on Wednesday.Hackers have long targeted Facebook users, sending them tainted messages via the social networking company's own internal email system. With this new attack, they are using regular Internet email to spread their malicious software. Read more: Reuters

Yahoo Pipes на страже автоматизации загрузок
|
Thursday, March 18, 2010
Многим из нас нравится загрузить RSS ленту в utorrent(или ему подобный поддерживающий загрузки с лент), настроить правила и в дальнейшем не заботясь о выходе новых серий любимого сериала, передач, видеть их скаченными по-приходу домой. И все хорошо, когда речь идет о Новафильме или Лосте, но мир не сошелся на них клином, часто хочется настроить автоматическую загрузку с другого трекера. А трекер конечно, как на зло не содержит в своей RSS ленте ссылки на .torrent файлы, ведь авторы хотят чтоб вы постоянно заходили к ним на сайт и набивали счетчик посещений, проводили там свое время. Сразу оговорюсь для чего мне это нужно. Я любитель посмотреть некоторые передачи регулярно выходящие на российском телеэкране. Все они постоянно записываются и выкладываются на различных «релизерских» трекерах, которые записывают ТВ вещание. В данной статье я рассмотрю такие как BigFANGroup и Кинозал.ТВ. Но вот беда, администрация забыла сделать понятной RSS ленту для торрент клиента, а может просто не захотела, ведь стоит мне настроить автоматическое скачивание и они лишатся уникального посещения каждый день. Сейчас с помощью Yahoo Pipes, мы решим эту проблему. На примере 2-х нужных мне трекеров я попытаюсь просто и понятно объяснить, как оптимизировать их ленты для автоматической загрузки. По аналогии данные способы можно применить и к любым другим ресурсам.Read more: Peer-to-Peer

Microsoft Employees Reveal Something Incredible
|
I bring you two pieces of shocking news this afternoon.No, really, sit down. I'm not responsible for the consequences if the following information causes your knees to give way out of pure shock. Are you ready? Phone in hand, just in case the news proves too much for your ticker and you need to dial 911? Then here we go: Shocking Item One: Some 10,000 Microsoft employees use the iPhone, at least based on unnamed sources quoted in The Wall Street Journal, who apparently pulled the information from smartphones accessing the company's e-mail system. (That's around 10 percent of its worldwide workforce.) Read more: Microsoft Watch

Installing and using Apache Cassandra With Java
|
I’m going to write a few postings on how to use the Cassandra database with Java, although i am in no way an expert on how to use Cassandra i am very intrigued about the database because of it’s small installation, high performance and scalability. During the writing of these posts i am also learning the Cassandra database and i’m sharing my experiences with it through my posts on this blog. Like i said before, Cassandra is a very high performing and scalable database, it doesn’t follow the normal SQL database principles like schema’s, tables / columns, datatypes and a query language like SQL. Instead it’s a non-relational database similar to Google’s BigTable. Cassandra was initially developed by Facebook which has contributed it to the open source community. Currently it is used by websites like Facebook, Twitter, Digg, Rackspace and many others. So even though it is still only version 0.6 at the time of writing this it has already proven itself in production environments. Some of the key-features of Cassandra: * Fault Tolerant – Data is automatically replicated to multiple nodes for fault-tolerance. Replication across multiple data centers is supported. Failed nodes can be replaced with no downtime.
* Decentralized – Every node in the cluster is identical. There are no network bottlenecks. There are no single points of failure.
* Flexible – Read and write throughput both increase linearly as new machines are added, with no downtime or interruption to applications.
* Highly Available – Writes and reads offer a tunable ConsistencyLevel, all the way from “writes never fail” to “block for all replicas to be readable,” with the quorum level in the middle.Read more: Sodeso

XBrowser - Headless Browser for .Net
|
XBrowser is a "headless" web browser written for .Net applications using C#. It is designed to allow automated, remote controlled and test-based browsing sessions without any actual rendering overhead. Whilst this is a new codeplex project, it has actually been used privately throughout several commercial projects, so has a good amount of maturity and debugging already behind it. As of first commit though, there is some tidy up and refactoring yet to be done before I am satisfied with giving it a "1.0" label. Currently there is no support for JavaScript; it is purely and simply HTML-based with session/cookies persistence, GET and POST operations, HTML parsing and an internal LINQ-to-XML-based document querying system. There is much to do but it is certainly usable in its current state.Please expect breaking changes in future releases.Read more: Codeplex

1. SST: referencesThis article is a logical continuation to the article "Driver to Hide Processes and Files" by Ivan Romananko. You can find all necessary information about System Service Table (SST) and its hooking in it. In this article I would like to present how to write your own unhooker that will restore original SST hooked by drivers like Ivan's one. 2. AlgorithmMy goal is to write a simple driver for SST hooking detection and removing purposes. This means that our driver should not use various Zw-functions and SST table because I suppose that SST table is corrupted by unknown rootkits. I do not care about filter drivers and function code splicers for now, but maybe I will come back to them in future. The simplest way to detect and remove hooks is to compare SST that is placed in memory with the initial SST from ntoskernel.exe file. So the goal is: 1. to find ntoskernel module in memory;
2. to find the section of ntoskernel where SST is placed and to calculate relative offset of SST in the section;
3. to find this section in the ntoskernel.exe file;
4. to calculate real address of SST in the file;
5. to read values from the file and to compare them with SST.But before the implementation I would like to present some additional information.3.

Did you know… you can have your External Tool’s text displayed in the Output Window ?
|
At the bottom of the External Tools dialog, you’ll see more options for customizing the external tool within visual studio. Today’s tip is about the Use output window option. The idea here is you’re running a .bat file, and you want to track the progress within Visual Studio. (and if you have a great real-world example, please leave a comment.) Using the command prompt as the tool, you can set the Arguments to something like “/C echo $(CurText)” where/C – from cmd.exe, carries out the command specified by string and then terminatesand $(CurText) is a token that comes from Visual Studio that represents the currently-selected text.Read more: Sara Ford's Weblog
What do those "IO requests taking longer than 15 seconds" messages on my SQL box mean?
|
You may be sometimes seeing stuck/stalled IO messages on one or more of your SQL Server boxes. This is something it is important to understand so I am providing some background information on it.Here is the message you may see in the SQL error log: SQL Server has encountered xxx occurrence(s) of IO requests taking longer than 15 seconds to complete on file [mdf_or_ldf_file_path_name] in database [dbname] (dbid). The OS file handle is 0x.... The offset of the latest long IO is: 0x....”. The message indicates that SQL Server has been waiting on at least one I/O for 15 seconds or longer. The exact number of times you have exceeded this time for the specified file since the last message is included in the message. The messages will not be written more than once every five minutes. Keep in mind that read IOs on an average system should take no more than 10-20ms and writes should take no more than 3-5ms (the exact acceptable values vary depending on your business needs and technical configuration). So anything measured in seconds indicates a serious performance problem. The problem is NOT within SQL Server, this message indicates SQL has sent off an IO request and has waited more than 15 seconds for a response. The problem is somewhere in the disk IO subsystem. For example, the disk IO subsystem may have more load than it is designed to handle, there is a "bad" hardware or firmware somewhere along the path, filter drivers such as anti-virus software are interfering, your file layout is not optimal, or some IO subsystem setting such as HBA queue depth is not set optimally. Though the root cause is IO, you can see other symptoms that are a side effect and may lead you down the wrong troubleshooting path. For example, if enough IO is backed up behind the stalled IO then you may see blocking in SQL Server (because locks that are usually taken for very short periods of time are now held for seconds), new connections may not be allowed, and the CPU usage can increase (because many threads are waiting), and a clustered SQL Server can fail over (because the IsAlive checks which are just SQL queries fail to complete like all the other queued queries). You may see other errors returned to the user or in the various logs, such as timeouts. There are two ways to approach this problem. You can either reduce the IO on the system (change indexes or queries or archive data for example) or you can make the underlying system able to handle the IO load (fix hardware/firmware problems, change configurations, add disks or controllers, change the file layout, etc.).

XmlWriter, encodings and BOM
|
Today I want to talk about XmlWriter and the generation of a Byte Order Mark (BOM).XmlWriter provides an API that generates, unsurprisingly, XML. This XML will typically end up as a managed string of characters or possibly a sequence of bytes. Of course, text transformed into bytes implies an encoding, as previously discussed. Now XML has its own ways of determining the encoding that a document has, by peeking at the first bytes that make up an opening <?xml declaration or, more explicitly, with the encoding on this declaration. Unicode is used for all sorts of puposes, not just XML encoding, and so it also has a mechanism to distinguish between small-endian and big-endian encodings, which determine which byte comes first in UTF-16 and UTF-32. It's also allowed for UTF-8, for that matter. How do these mechanisms interact when using the .NET Framework classes? Let's write some code!First, we'll write a short helper method to display the contents of a byte array.private static void ShowBuffer(string linePrefix, byte[] bytes, long length) {
int bytesOnLine = 0;
for (long i = 0; i < length; i++) {
if (bytesOnLine == 0) {
Console.Write(linePrefix);
} Console.Write("{0:X2} ", bytes[i]);
bytesOnLine++;
if (bytesOnLine > 16) {
Console.WriteLine();
bytesOnLine = 0;
}
}

Detecting memory leaks using the CrtDbg Library
|
Memory is a very important aspect for an application to run. Applications that leak large amounts of memory or leak progressively may display symptoms ranging from poor (and gradually decreasing) performance to running out of memory completely. Worse, a leaking program may use up so much memory that it causes another program to fail, leaving the user with no clue to where the problem truly lies. In addition, even harmless memory leaks may be symptomatic of other problems. When an application is very big, it could have having 100+ files and 1000+ functions and it would be tough to find memory leaks in the application, so we can use the CrtDbg Library APIs to find the memory leaks in that application. For memory leak detection, we have so many tools available in the market, but for them you need to pay a lot. This article talks about a C Runtime Library which is free and available with all Windows OSs, and is called the CrtDbg Library. This library provides APIs which can be used to detect memory leaks. Using the codeWe can use CrtDbg library functions to detect the memory leaks in our application.The technique for locating memory leaks involves taking snapshots of the application's memory state at key points. The CRT library provides a structure type, _CrtMemState, which you can use to store a snapshot of the memory state:
Collapse_CrtMemState s1, s2, s3;To take a snapshot of the memory state at a given point, pass a _CrtMemState structure to the _CrtMemCheckpoint function. This function fills in the structure with a snapshot of the current memory state:
Collapse_CrtMemCheckpoint(&s1);After calling _CrtMemCheckpoint(&s1), code can be written in which we can detect the memory leak. (_CrtMemCheckpoint can be used anywhere in the code.)After writing your code, use _CrtMemCheckpoint( &s2 ) to take another snapshot of the memory at that time; after that, you can call _CrtMemDifference(&s3, &s1, &s2). _CrtMemDifference compares two memory states s1 and s2, and returns their differences (debug version only). _CrtMemDifference(&s3, &s1, &s2) will return 0 if there is no memory leak between the s1 and s2 memory checkpoints, and returns 1 if the code written between the checkpoints s1 and s2 has a memory leak.

uTorrent banned by private trackers for "not playing fair"
|
We told you a while ago about uTP, the new self-throttling torrent transfer protocol that first appeared in version 2.0 of the popular uTorrent app. As Sebastian explained in our previous post, uTP prevents network congestion by limiting its own bandwidth so that your Internet service provider doesn't have to. Ideally, this means nobody is subjected to ISP-level torrent throttling, and everybody wins. In practice, though, uTorrent may be unfair in a different way: it gives priority to other users who are running the new protocol. That's caused several private trackers to boot uTorrent 2 off of their approved clients lists. Bittorrent Inc., the developers of the uTP protocol, has opened it up so that other torrent clients can incorporate it. Bittorrent Inc. admits that there might be a "downside to innovation" in this case, according to Torrentfreak, but it's working to take uTP mainstream, which would solve the problem. Other major clients, including Vuze, are already looking at incorporating the protocol into their software. Read more: Downloadsquad

SEC: Hacker Manipulated Stock Prices
|
U.S. regulators are moving to freeze the assets and trading accounts of a Russian accused of hacking into personal online portfolios and manipulating the price of dozens of stocks listed on the Nasdaq Stock Market and New York Stock Exchange. A New York federal judge on Tuesday sided with the Securities and Exchange Commission and froze the assets of Broco Investments, believed to be a one-trader operation based in St. Petersburg, Russia. The SEC said Broco capitalized by artificially moving prices of more 38 thinly traded securities — enabling Broco to profit from up-or-down price swings. “These transactions have created the appearance of legitimate trading activity and have artificially affected the prices of at least 38 issuers,” (.pdf) the Securities and Exchange Commission said in court filing.

MS Virtual PC Flaw Defeats Windows Defenses
|
An exploit writer at Core Security Technologies has discovered a serious vulnerability that exposes users of Microsoft's Virtual PC virtualization software to malicious hacker attacks. The vulnerability, which is unpatched, essentially allows an attacker to bypass several major security mitigations — DEP, SafeSEH and ASLR — to exploit the Windows operating system. As a result, some applications with bugs that are not exploitable when running in a not-virtualized operating system are rendered exploitable if running within a guest OS in Virtual PC Read more: Slashdot

Have you ever had to create a custom report within an application you have written for a customer? Most developers have, and there are two schools of thought on how developers normally perform this task. Some choose to create the report using the same technology that the application was created in (ASP, WinFrom, WPF) while others choose to use a reporting package such as Crystal Reports. Using a reporting package will help create reports rapidly. This article walk you through the creation of your first report using Crystal Reports. by Jeff McWherter

Unreal Engine games add Nvidia 3D display
|
Stereoscopic technology to be integrated into Epic’s leading engine. Nvidia has sealed a deal with Epic Games to bring stereoscopic 3D technology to PC titles built using the Unreal Engine. Unreal-made PC games – which have in the past included Batman Arkham Asylum, Gears of War and Mass Effect 2 – will soon be able to integrate more easily with Nvidia’s 3D Vision package. Out of the box support for the 3D technology will be available after Unreal Engine 3’s next update. The chipmaker’s Vision package consists of wireless stereoscopic glasses and a USB emitter which, at least on PC monitors running at 120Hz, can bring games out into a full 3D display. “The combination of Unreal Engine 3 and 3D Vision makes already amazing games even more jaw dropping,” said Epic Games vice president Mark Rein.

Unit Testing in JavaScript. Introduction

JavaScript is mainly (but not only!) clientside language. Therefore it poses some problems for developers who use unit testing in their projects. I’m going to point out most of them and solve bit by bit in next articles. If you don’t need explanation of this term itself, proceed right to the JavaScript Issues title.
Unit TestingIn short: We’re writing tests for our application which are independent of each other. We may quickly execute set of them as we modify the code. The new application is error-free if all go positively. Unit Testing is connected with Agile methodology and techniques of producing a software such as Extreme Programming (XP) or Test-driven development (TDD). They assume that changes in application should be made frequently and in small portions. Unfortunately, it’s equivalent to frequent errors. Thanks to Unit Testing we are able to detect them rapidly.

A Quick-Start Guide of Process Mandatory Level Checking and Self-elevation under UAC
|
IntroductionUser Account Control (UAC) is a new security component in Windows Vista and newer operating systems. With UAC fully enabled, interactive administrators normally run with least user privileges. This article and the attached code samples demonstrate these frequently asked coding scenarios related to UAC. 1. How to check if the current process is running as administrator?
2. How to know if the primary access token of the current process belongs to user account that is a member of the local Administrators group, even if it currently is not elevated?
3. How to check if the current process is elevated? The elevation information is available to only Windows Vista and newer operating systems because there was no UAC and "elevation" before Windows Vista.
4. How to get the integrity level of the current process (System/High/Medium/Low/Unknown)? The integrity level information is available to only Windows Vista and newer operating systems because there was no UAC and "integrity level" before Windows Vista.
5. How to show a UAC shield icon on the UI for tasks that require elevation?
6. How to self-elevate the current process?
7. How to automatically elevate the process when it's started up?We provide code samples to demonstrate the above how-to scenarios in three programming languages (native VC++, VC#, VB.NET) to meet the needs of different developers. Read more: Codeproject

Transparent Data Encryption
|
Transparent Data Encryption is designed to protect data by encrypting the physical files of the database, rather than the data itself. Its main purpose is to prevent unauthorized access to the data by restoring the files to another server. With Transparent Data Encryption in place, this requires the original encryption certificate and master key. It was introduced in the Enterprise edition of SQL Server 2008. John Magnabosco explains fully, and guides you through the process of setting it up. How TDE WorksTransparent Data Encryption (TDE) was introduced in SQL Server 2008, as a feature of the Enterprise Edition of that product. The Developer Edition of SQL Server 2008 also offers TDE, but its license limits its use to development and testing only. As noted above, TDE's specific purpose is to protect data at rest by encrypting the physical files of the database, rather than the data. These physical files include the database file (.mdf), the transaction log file (.ldf) and the backup files (.bak). The protection of the database files is accomplished through an encryption key hierarchy that exists externally from the database in which TDE has been enabled. The exception to this is the database encryption key, which was introduced to the database encryption key hierarchy specifically to support the TDE feature, and is used to perform the encryption of the database files.

PROBLEM:When you open SQL Server 2008 configuration manager you do not see the following options :Scenario 1 (64 bit options):
1) SQL Native Client 10.0 configuration
2) SQL Server Network configuration Scenario 2 (32 bit options):
1) SQL Native Client 10.0 configuration(32 bit)
2) SQL Server Network configuration (32 bit)CAUSE:SQL Server configuration manager pulls the details with the help of SQLMGMPROVIDER.DLL.
This DLL has got two versions - one is 64 bit and the other is 32 bit :

Elmah vs Logging
|
Elmah — это очень полезный инструмент протоколирования ошибок веб-приложения ASP.NET. Часто можно услышать вопрос: что лучше использовать — Elmah или библиотеку логгинга (например, log4net)? Чтобы ответить на этот вопрос, нужно понять какие функции выполняет каждый из эти инструментов. Основные функции Elmah: * logging (протоколирование) — логгирование ошибок со всей сопутствующей информацией;
* reporting (отчетность) — предоставление информации об ошибках пользователю в удобном для чтения виде;
* notification (уведомление) — уведомление пользователя о случившейся ошибке. В качестве примера библиотеки логгинга в этом вопросе используется log4net, так что в дальнейшем повествовании понятия «log4net» и «библиотека логгинга» употребляются как синонимы. Итак, основная функция log4net только одна: * logging — протоколирование событий, происходящих в приложении;Из приведенных списков видно, что log4net не обладает многими возможностями Elmah: * log4net не решает задачу reporting`а. Библиотека логгинга просто сохраняет протокол событий в определенном хранилище и не заботится об удобном представлении этого протокола пользователю. Доступные средства просмотра логов также не обеспечивают требуемого удобства, потому что они не предназначены для представления веб-специфичных параметров.
* log4net не решает задачу уведомления пользователя об ошибке. Можно, конечно, использовать appender, отсылающий UDP пакеты или написать свой, но изначально log4net не предназначен для решения таких задач.Кажется, что log4net отстает по всем пунктам. Но, с другой стороны, Elmah покрывает задачу логгинга не полностью. Ведь в протокол попадают только ошибки, в то время как в приложении может понадобиться следить за логикой последовательной работы нескольких систем и протоколировать множество дополнительной информации. log4net же поддерживает сообщения разных уровней — DEBUG, INFO, WARN, ERROR, FATAL.

Performance tuning a server in less than three minutes while being slashdotted
|
So you wrote a blog post about something that seemed fairly innocuous, but for whatever reason, it caught the attention of one of the major sites and now your server load is at 110 and climbing, the ssh command line session is taking thirty seconds to respond to anything at all, and given that your post is on the front page of slashdot at primetime, this doesn’t look like it’s a temporary blip. What do you do? Okay, first things first. You don’t have time to do a proper fine-tuning session. You need a quick & dirty tuneup here. Proper fine tuning you leave till after the traffic spike, and you can then come back at it with a plan and decent tools like siege and so on – but this is the “fix it in three minutes” version. So if you see stuff here that looks crude to you, despair not, everything looks crude when you’re trying to do it in that kind of timeframe. First, you have to be able to actually use the server command line. The load’s at 110 – that’s not coming down anytime soon and until it does you can’t do the rest of the work you need to since it takes so much time for even a shell to respond. The load is being caused by Apache and MySQL taking on more work than the server can handle, causing the server to swap excessively; and you’ve got to dump that work or shut off the incoming new work to recover. You can try sudo killall -9 apache2 if you can get an open ssh terminal in to do the job (and it’s the first thing you should try), but the odds are that that server has to be reset. Whether that means a phone call to the data centre, or a walk down the hall to the server room, or just clicking a button in a web interface, that’s the first thing to do. Don’t hold off, because unless everyone stops reading your page right now, that load’s not coming down. Once the box has rebooted (and I mean immediately – sit there watching ping until it comes back), ssh in and shut down apache. MySQL is okay for now, but the work is coming from Apache, so that has to get shut down until everything’s ready to go again. You’re going to lose a few minutes of service, yes, but that’s recoverable from for a blog (and if this is for something more serious than a blog, you’re going to be in trouble for not properly spec’ing the hardware to begin with anyway, so limit the damage now and take your licks later).

SQL Style Extensions for C#
|
Are you addicted to SQL? Are you uncomfortable whenever you have to use pesky imperative languages like C#? Now you can use your favourite SQL functions inside C#, with the amazing new "SQL Style Extensions" class! Need to know if a value is in a short list of constants? In SQL you'd simply write "where State in ('QLD','NSW','VIC')" – but, until recently C# forced you to write: if (State == "QLD" || State == "NSW" || State == "VIC") But now -- thanks to the aMAZzing new 'SQL Style Extensions' -- you can simply write: If (State.In("QLD","NSW","VIC")) ... then close down the IDE and get back to your Entity Diagrams in no time!Do you miss the power of LIKE matching?Read more: SecretGeek

Converting C# to COBOL
|
DescriptionI did a previous article, (August 22, 2009) on converting the many C# examples to COBOL. At the time there were a few examples out in the world of how to perform this conversion. Since that article has been written more and more examples have been popping up. In this article I'd like to introduce you to a co-worker of mine who has presented what I believe to be the ultimate wall chart. This article is intended to be used as a model for you to follow when you run into a C# example and need to convert it to COBOL. Visual COBOL!I recently published a blog about a new product being introduced by Micro Focus called 'Visual COBOL'. Visual COBOL will be a whole new product from Micro Focus, not a rebranded current version of one of the compilers. Visual COBOL will have new syntax available that will make coding COBOL in the .NET environment much simpler and stream lined. In my previous article I proposed creating two projects, one in COBOL and the other in either C# or VB.NET. This was to enable you to learn the art of utilizing, and hopefully understanding, the realm of .NET namespaces and classes. By using the other .NET languages you could see how the syntax was composed and then translate that into COBOL. I used this method because there was no really good reference material out there at the time. Well guess what...someone created what I believe is the ultimate syntax example. A while ago I was in Newbury at our headquarters testing the latest release of Visual COBOL. I had the pleasure of meeting some very talented developers. One of them, Dr. Alex Turner, had mentioned he composed a chart showing the syntactical differences between C#, VB.NET and COBOL. NET. My initial thought was that's cool, a couple more examples that we can use and blog about. Man was I ever wrong! Alex, I publicly apologize for underestimating your resourcefulness!

Fixing my SQL Directory NTFS ACLS
|
I run my development server by boot to VHD (Windows Server 2008 R2 x64). In that instance, I also have an attached VHD (I attach via script at boot up time using Task Scheduler). That VHD I have my SQL instances installed. So, the other day, acting hasty, I chmod my ACLS – wow, what a day after that.So, in order to fix it I created this set of BAT commands that resets it back to operational state – not 100% of all what you get, I also didn’t want to run a “repair” – but, all operational again. setlocal SET Inst100Path=H:\Program Files\Microsoft SQL Server\100REM GOTO SQLESET InstanceName=MSSQLSERVER

Get Safe File Name
|
Here’s a quick utility that might come in handy. More than once I’ve seen code where the invalid chars were hard coded. The Path.GetInvalidFilenameChars has been in the .NET Framework since 2.0.The thing is you would expect something like this to be in the framework itself. /// <summary>
/// Removes invalid characters from the string that is passed in.
/// </summary>
/// <param name="name">The name of the file.</param>
/// <returns>The safe name with invalid chars removed.</returns>
public static string GetSafeFileName(string name)
{
var safeName = new StringBuilder();
foreach (var c in name)
{
if ((from p in Path.GetInvalidFileNameChars() where p == c select p).Count() == 0)
{
safeName.Append(c);
}
}
return safeName.ToString();
}Chris Martin posted an even tighter version of this code in the comments below. Thanks Chris.Read more: merill.net

Moq Examples
|
My friend Jon is starting a training course in an effort to quickly bring developers up to speed on test driven development. As part of this effort, he has developed a unit test suite aimed at helping folks understand Rhino Mocks, a popular testing tool. After looking through the tests and seeing a lot of the Rhino API that I wasn’t familiar with, I wondered if there were similar undiscovered nooks in my favorite mocking framework: Moq. After getting permission, I took his tests that use Rhino Mocks and implemented them with Moq. It was a great exercise for not only learning the two APIs, but also for getting a side by side comparison of the frameworks. The differences in most cases are subtle, and ultimately I found the choice between each to be a matter of taste. You can find Jon’s tests here, and mine here.
Points of InterestMocks & Stubs?I’m in agreement with Jon that the differences between mocks and stubs are mostly semantic, and are best reserved for academic discussions. I called all the variables in my tests “mock” because the class for creating mocks and stubs with Moq is “Mock”.
API SurfaceThe reason I am such a fan of Moq is that the API “surface” is minimalistic. The methods I want to use most often are within clear sight and meaningful. There’s not a lot of extra jargon and noise that I have to think about. The methods that I use 20% of the time are tucked away in a manner that is still discoverable, but yet hidden enough to give me a signal that they’re not the first path I should choose.

SQL SERVER – MAXDOP Settings to Limit Query to Run on Specific CPU
|
Tuesday, March 16, 2010
This is very simple and known tip. Query Hint MAXDOP – Maximum Degree Of Parallelism can be set to restrict query to run on a certain CPU. Please note that this query cannot restrict or dictate which CPU to be used, but for sure, it restricts the usage of number of CPUs in a single batch. Let us consider the following example of this query.The following query usually runs on multicore on a dual core machine (please note it may not be the case with your machine).USE AdventureWorks

How to build your own DropBox personal clone
|
DropBox is a great time saver but it’s very limited in storage space. There seems to be no real other free alternative services (all online storage services don’t do automatic synchronisation and are not seamlessly integrated with the OS explorer). So why not look at opensource solutions ? There seems to be any ready-made one so you have to build it yourself by assembling several systems. fak3r has been experimenting with this; you can read his step by step instructions here though I didn’t test them myself as I don’t have a Linux but a Windows system. Any suggestion for Windows welcome or I will have to setup Linux one day Read more: Ask Superuser

XPerf Tool – Why Can’t You Live Without It?
|
Israel Burman (Israel is one of the ADPlus creators and the guy who taught me the XPerf tool) and Mario Hewardt told me I should blog about the XPerf tool.
Although I’m new to this tool I decided to follow their suggestions because I believe you’re going to wonder how you could live without using this tool after using it for the first time. J So, when starting to write this article I decided to browse the internet to see how many articles from Microsoft I could find because I didn’t want to be redundant. As a matter of fact I found several great articles. (Am I late to the party? J) Some of these articles are very didactic and similar to what I had in mind. That said, I’m not going to be redundant here, likewise I’m going to give you just an overview about the tool and mention those articles that details the configuration and usage of XPerf so you can get the necessary details from these articles without having to research the internet all over again. WHAT’S XPERF?- XPerf is based on ETW (Event Tracing for Windows) which is a very efficient tracing infrastructure.
- The overhead caused by XPerf is about ~2.5% CPU, in other words, very minimum.
- The tracing can be dynamically enabled or disabled and it doesn’t require a reboot.
- XPerf enables you to collect logs, create reports and see charts from the collected data. Israel Burman (Israel is one of the ADPlus creators and the guy who taught me the XPerf tool) and Mario Hewardt told me I should blog about the XPerf tool.

WHEN SHOULD YOU USE XPERF? - When you need to isolate performance problems.
- To get a better understanding of the Operating System.

As a matter of fact I found several great articles. (Am I late to the party? J) Some of these articles are very didactic and similar to what I had in mind. That said, I’m not going to be redundant here, likewise I’m going to give you just an overview about the tool and mention those articles that details the configuration and usage of XPerf so you can get the necessary details from these articles without having to research the internet all over again. WHAT’S XPERF?- XPerf is based on ETW (Event Tracing for Windows) which is a very efficient tracing infrastructure.
- The overhead caused by XPerf is about ~2.5% CPU, in other words, very minimum.
- The tracing can be dynamically enabled or disabled and it doesn’t require a reboot.
- XPerf enables you to collect logs, create reports and see charts from the collected data. Israel Burman (Israel is one of the ADPlus creators and the guy who taught me the XPerf tool) and Mario Hewardt told me I should blog about the XPerf tool.

WHEN SHOULD YOU USE XPERF? - When you need to isolate performance problems.
- To get a better understanding of the Operating System.
- Probably other scenarios where you can benefit for tracing the Windows components. WHEN SHOULD YOU USE XPERF?- When you need to isolate performance problems.

Announcing the Release of the Open XML SDK 2.0
|
Today, I am really excited to announce the worldwide availability of the Open XML SDK 2.0 for Microsoft Office! The Open XML SDK plays an integral part in creating Office document solutions that work on the client or server. The Open XML SDK allows you to create, consume, and manipulate Open XML files without needing to automate Office client applications. Combining the power of Office Services and the Open XML SDK enables even more scenarios, such as rich server-side document assembly solutions. No longer will you need to pay special attention to one of Office's most popular knowledge base articles that talks about how automating Office client applications on the server is not supported (http://support.microsoft.com/kb/257757). Development of the Open XML SDK 2.0 spanned almost two years and involved the release of four Technical Previews in addition to the final release announced today. Your feedback via the blogs, MSDN forums, www.openxmldeveloper.com forums, and Microsoft Connect site helped shape the overall design of the SDK. Thank you so much for your support and feedback! Please feel free to continue sending us feedback with respect to the Open XML SDK. Learn More about the Open XML SDKOver the past year and a half, I have shown you guys a lot of real world scenarios/solutions that are built with the SDK. Here is a summary of links that will help you learn more about the Open XML SDK:

Установка Windows 7 с флешки, правка дистрибутива Windows 7 с MDT
|
Для начала давайте подготовим наш дистрибутив. Начиная с ОС Windows Vista для правок дистрибутива используется WAIK, это очень мощный продукт, с помощью которого можно провести множество манипуляций, но он не очень простой в использовании. В большинстве случаев рядовому пользователю не нужны все все функции WAIK, именно поэтому было создано приложение MDT которое удобнее и проще чем WAIK. Итак приступим.
Подготовка средыЧтобы следовать инструкциям этого руководства, вам необходимо настроить следующую среду (или подобную): * Контроллер домена для домена contoso.com.
* DHCP сервер с настроенным границами для аренды адресов клиентским компьютерам.

Open Source Android Applications for developers
|
As an Android apps developer, the best case study may be the open source android applications or samples. Below is my memo of open source android applications which I have found in the Internet, hope this will be useful for you. No.1: Android SDK Samples: The best way to learn how things are done is to look at some code.Website: http://developer.android.com/resources/samples/index.html To help Android developers get started quickly, the Android SDK includes a variety of sample code and tutorials that illustrate key concepts and techniques of Android application development. The list below provides a summary of the sample applications that are available with the Android SDK: 1. API Demos
A variety of small applications that demonstrate an extensive collection of framework topics.2. Bluetooth Chat
An application for two-way text messaging over Bluetooth.3. BusinessCard
An application that demonstrates how to launch the built-in contact picker from within an activity. This sample also uses reflection to ensure that the correct version of the contacts API is used, depending on which API level the application is running under.

Visual Guide to NoSQL Systems
|
There are so many NoSQL systems these days that it's hard to get a quick overview of the major trade-offs involved when evaluating relational and non-relational systems in non-single-server environments. I've developed this visual primer with quite a lot of help (see credits at the end), and it's still a work in progress, so let me know if you see anything misplaced or missing, and I'll fix it.
Without further ado, here's what you came here for (and further explanation after the visual).
Note: RDBMSs (MySQL, Postgres, etc) are only featured here for comparison purposes. Also, some of these systems can vary their features by configuration (I use the default configuration here, but will try to delve into others later).

Using TCP for Low-Latency Applications
|
Last week I ran into a nasty little problem while implementing an application with soft real-time requirements. I was aiming at 1 ms or less for a TCP-based request-response roundtrip on a local network. Should be trivial, but why did my tests indicate that I wasn’t even getting close? The scenario was simple: A server (my part) gets a request from a client. Before it can answer, it has to ask a backend system for some information. The backend system listens on a TCP port and answers in a query-response fashion (processing time is far below 1 ms). Both query and response typically fit in a single TCP segment. The response may sometimes be larger, which is one reason why TCP was an adequate choice for the backend system. As a first optimization I used a TCP connection pool to get around TCP’s three-way handshake (SYN, SYN ACK, ACK) and thus cutting down latency. However, tracing showed response times around 40 ms on the local network. Actually worse than without the connection pool! Admittedly, the conventional use for connection pools is to circumvent TCP’s slow start mechanism. But still, something was very wrong. Read more: Unmaintainable

Silverlight at Windows Phone 7
|
Microsoft announced today, that new Windows Phone 7 Series will support Silverlight as one of 2 development frameworks. Second development framework will be XNA (will blog about it later). So, what’s new for Silverlight developers there?First, we have familiar tools: Windows Phone applications with Silverlight will be developed either with Visual Studio 2010, either with new “express” version called Visual Studio 2010 Express for Windows Phone. This “express” version will enable development with both frameworks (Silverlight and XNA). Full Visual Studio 2010 will also get new project types to develop with both frameworks.Read more: DevCorner
SQL Express is not installed properly. Steps to be taken before reinstall again

What Is gpkcs11?
It is an implementation of the PKCS #11: Cryptographic Token Interface Standard, that you may freely download and distribute.This software is only available in source code and is distributed under the GNU Lesser General Public License (LGPL). The source code package also includes an interactive shell that is released under the GNU General Public License (GPL). Please refer to the file README for further explanations. Please note that this software is aimed at developers of applications with cryptographics functions and requires programming expertise to make use of. gpkcs11 is still in development and may lead to loss of data and has potential security holes. TC TrustCenter is not liable to any damages, direct or indirect, that arise through the use of the software. PKCS#11 defines an interface for the communication of arbitrary applications with systems that perform cryptogrphic operations, like en- and decryption, signing and verifying. These systems, called token, may be Chipcards (with appropriate reader), discrete hardware systems or pure software implementations. gpkcs11 provides support functions to make the development of support for new tokens easier and contains a complete software token, as well as an automated testing environment. In a later version this software token will be usable as complete and secure tool for cryptographic applications. In this phase gpkcs11 may serve as a testing tool in the development of new applications that contain cryptographic support. Here you may download the latest version. The code was tested on Solaris 2.5.1/SPARC and successfully compiles on Linux 2.0.36/i386 as well. It should run on other UNIX platforms as well. Only the creation of shared libraries may cause problems. The libtool is used in order to help solve those problems on plattforms where it is supported. Unfortunately we do not have acces to other plattforms, but would be very interested in any reports on your experiences. The development is being done on Windows NT in parallel, and is buildable on it as well. Starting with version 0.5.6 for the the workspace and project files for Microsofts Visual C++ 6.0 are included. This is a kind of trial balloon. The whole system is not buildable without manual intervention (e.g. you still need the seperate OpenSSL library). But the projects should help build gpkcs11 on Win32. Read more: gpkcs11

SWIG is a software development tool that connects programs written in C and C++ with a variety of high-level programming languages. SWIG is used with different types of languages including common scripting languages such as Perl, PHP, Python, Tcl and Ruby. The list of supported languages also includes non-scripting languages such as C#, Common Lisp (CLISP, Allegro CL, CFFI, UFFI), Java, Lua, Modula-3, OCAML, Octave and R. Also several interpreted and compiled Scheme implementations (Guile, MzScheme, Chicken) are supported. SWIG is most commonly used to create high-level interpreted or compiled programming environments, user interfaces, and as a tool for testing and prototyping C/C++ software. SWIG can also export its parse tree in the form of XML and Lisp s-expressions. SWIG may be freely used, distributed, and modified for commercial and non-commercial use. Read more: SWIG
PKCS Standards and .NET Framework
|
This article will introduce the reader to the Public Key Cryptography Standards (PKCS). The emphasis will be on what is standardized in the PKCS (Public Key Cryptographic Standards) standards and the implementation in .NET 1.1 Framework. This tutorial assumes that the reader is familiar with basic terms in cryptography such as Public Key cryptography, Secret Key cryptography and Message Digest algorithms. PKCS StandardsThe PKCS standards are specifications that were developed by RSA Security in conjunction with system developers worldwide (such as Microsoft, Apple, Sun etc.) for the purpose of accelerating the deployment of public key cryptography. The goal is to facilitate early adoption of these standards by vendors. These standards are used everywhere in the e-security realm. Any application developer choosing to implement security into his/her application would stumble upon these standards at some point of time. Applications ranging from web browsers to secure email clients depend on the PKCS standards to interoperate with one another. PKCS is defined for both Binary and ASCII messages in an abstract manner giving complete specifications. The representation format for the encoded messages is a preferred format. (The companion documents are ASN.1 = Abstract Syntax Notation 1, BER = Basic Encoding Rules, DER = Distinguish Encoding Rule). Standards DescriptionPKCS # 1 The RSA encryption standard. This standard defines mechanisms for encrypting and signing data using the RSA public key system.
PKCS # 3 The Diffie-Hellman key-agreement standard. This defines the Diffie-Hellman key agreement protocol.
PKCS # 5 The password-based encryption standard (PBE). This describes a method to generate a Secret Key based on a password.
PKCS # 6 The extended-certificate syntax standard. This is currently being phased out in favor of X509 v3.
PKCS # 7 The cryptographic message syntax standard. This defines a generic syntax for messages which have cryptography applied to it.
PKCS # 8 The private-key information syntax standard. This defines a method to store Private Key Information.
PKCS # 9 This defines selected attribute types for use in other PKCS standards.
PKCS # 10 The certification request syntax standard. This describes syntax for certification requests.
PKCS # 11 The cryptographic token interface standard. This defines a technology independent programming interface for cryptographic devices such as smartcards.
PKCS # 12 The personal information exchange syntax standard. This describes a portable format for storage and transportation of user private keys, certificates etc.
PKCS # 13 The elliptic curve cryptography (ECC) standard. This describes mechanisms to encrypt and sign data using elliptic curve cryptography.
PKCS # 14 This covers pseudo random number generation (PRNG). This is currently under active development.
PKCS # 15 The cryptographic token information format standard. This describes a standard for the format of cryptographic credentials stored on cryptographic tokens. Note: PKCS #2 and #4 do not exist anymore because they have been incorporated into PKCS #1.Read more: Codeproject
PKCS # 3 The Diffie-Hellman key-agreement standard. This defines the Diffie-Hellman key agreement protocol.
PKCS # 5 The password-based encryption standard (PBE). This describes a method to generate a Secret Key based on a password.
