Free Certification Exams for Visual Studio 2010

- by budugu

Get promotional codes from herehttp://blogs.msdn.com/gerryo/archive/2010/03/17/register-for-visual-studio-2010-beta-exams.aspx You don’t have to pay anything to take these exams. These are 100% free. If you pass the exam, you earn the certification just the same as if you took it in a non-beta environment. From Gerry O'Brien’s blog... 2) Is this a real exam? – Yes it is. Even though the questions are not scored at the time you take the exam, they are real questions and the exam is real. If you pass the exam, you earn the certification just the same as if you took it in a non-beta environment. This means you don’t get a pass/fail or score immediately following the exam, but you do get notified 8 to 10 weeks later because we move slow in getting the final scoring in place. 4) What is the main difference between a beta and non-beta exam, besides cost? – The beta exam will show you questions that have not been through a final QA check. You are that final QA check. Non-beta exams expose you to 40 or 45 questions and you have a total of two hours to complete it. The beta exam could expose you to as many as 125 to 150 questions and take up to four hours. Following exams are for Asp.Net developers Exam 71-515, TS: Web Applications Development with Microsoft .NET Framework 4Exam 71-519: Pro: Designing and Developing Web Applications Using Microsoft .NET Framework 4

Ambiguation between multitouch geistures tap and free drag in Windows Phone 8 Emulator (Monogame)

- by Moses Aprico

I am making a 2d tile based tactic game. I want the map to be slided around (because it's bigger than the screen) with FreeDrag (It's perfectly done, the map can moved around, that's not the problem). And then, I want to display the character's actions, everytime it's tapped. The problem then appeared. Everytime I want to FreeDrag the map, the Tap trigger always fired first before the FreeDrag one. Is there any way to differ the map sliding than the character tapping? Below is my code. while (TouchPanel.IsGestureAvailable) { GestureSample gesture = TouchPanel.ReadGesture(); switch (gesture.GestureType) { case GestureType.FreeDrag: { //a } break; case GestureType.Tap: { //b } break; } } Every time I first want to free drag (at the first touch), it always goes to "b" first (see commented line above), and then to "a" rather than immediately goes to "a". I've tried flick, but it seems the movement produced by flick is too fast, so freedrag fits the most. Is there any way or workaround to perform FreeDrag (or similar) without firing the Tap trigger? Thanks in advance.

rsync'd a folder, folder doesn't show up, but free disk space decreased

- by Patrick

I am currently trying to switch from mac to windows/ubuntu dual boot (on 2 seperate internal HDDs), but ran into some trouble restoring my documents. I am not sure all the information below is necessary, but if I knew how to solve it, I wouldn't ask it here. I backed up my mac before buying this laptop on an external HDD with Carbon Copy Cloner. I wanted to put these files on my user folder on my windows HDD, but I could not do that from inside windows (HFS+ format of mac), so I used rsync from inside Ubuntu to copy the documents from the ext hdd to the windows partition. It seemed like it went okay, but from inside windows (and later also Ubuntu) the folder didn't show up. My free HDD space, however, has reduced with about 200 GB (the size of the backup) when looking at the disk properties (from inside Windows and Ubuntu). rsync command I used: rsync -av /media/patrick/Toshiba\ 1.5T/Users/patrickvandenberg/ /media/patrick/Windows8_OS/Users/Patrick/MacBackup/ Folder does not exist: patrick@patrick-Lenovo-IdeaPad-Y410P:~$ cd /media/patrick/Windows8_OS/Users/Patrick/MacBackup bash: cd: /media/patrick/Windows8_OS/Users/Patrick/MacBackup: No such file or directory Size of disk: patrick@patrick-Lenovo-IdeaPad-Y410P:~$ du -hs /media/patrick/Windows8_OS/ 195G /media/patrick/Windows8_OS/ Size of disk according to Disk properties: http://i.stack.imgur.com/OteMX.png (not enough rep to insert the image)

SQL SERVER – Load Generator – Free Tool From CodePlex

- by pinaldave

One of the most common questions I receive is if there any tool available to generate load on SQL Server. Absolutely there is a fabulous free tool available to generate load on SQL Server on Codeplex. This tool was released in 2008 but it is still extremely relevant to generate the load on SQL Server as well works fabulously. CodePlex is a project initiated by Microsoft for hosting open source softwares. The best part of this SQL Server Load Generator is that users can run multiple simultaneous queries again SQL Server using different login account and different application name. The interface of the tool is extremely easy to use and very intuitive as well. One of the things which I felt needed improvement was a default configuration. As every single time when I was adding a query the default settings were showing up and I had to manually change that. However, when I went to Menu >> Tools >>Options I was really happy as it has options to change every single default which is available. Here one can give default username, password, database name as well various settings related to configuration. Additionally application logging is also possible through the options. A couple of other important points I noticed was the button to reset counters as well status bar containing useful information of Total Threads, Completed Queries and Failed Queries. I use this frequently for my load testing. What tool do you use for SQL Server Load Generator?

Free space in tmpfs partition not adding up

- by Dean Herbert

I have had my /tmp/ partition filling up recently when it should not be anywhere near full. On further investigation, I found that the partition was listing free space a lot lower than it should be. I am guessing a remount will fix this, but am very curious as to why this has happened and where this space has gone. du output: root@odoroki:/tmp# du --summarize -h 3.3M . df output: root@odoroki:/tmp# df -h /tmp Filesystem Size Used Avail Use% Mounted on tmpfs 3.9G 3.3G 653M 84% /tmp Update: after deleting some files it has happened again. du output: root@odoroki:/tmp# du -h --summarize 11M . df output: root@odoroki:/tmp# df -h /tmp Filesystem Size Used Avail Use% Mounted on tmpfs 3.9G 3.9G 0 100% /tmp I have a feeling this has started since a recent apt-get upgrade, but it still seems like strange behaviour. I did do a quick scan over lsof output and couldn't see any open/stuck file handles. Unfortunately due to the seriousness of the issue I had to reboot the server, after which usage seems to match correctly.

Fiddler - A useful free tool for checking Web Services (and web site) traffic

- by TATWORTH

Recently I had reason to be very glad that I had Fiddler. I was able to record some web service traffic and identify a problem as Fiddler can record both the call to a web service and response from the web service. By seeing the actual data traffic I was able to resolve a problem found in testing in less time than it has taken me to write this blog entry! This tool is also useful for studying general web site traffic. Fiddler is available from http://www.fiddler2.com/fiddler2/ There are training videos available on the above site.

Getting file system free space

- by Fred Riley

This isn't a problem as such, more a request for information based on ignorance of the Linux filesystem. The very short question is: How do I find out how much free and used space there is on the volume from which Ubuntu is running? More detail: I'm running Ubuntu 12.04 from a 64Gb USB3 stick, created from booting up a year-old Ubuntu 12.04 DVD and running Startup Disk Creator. The reason for this is that the Master Boot Record on my hard disk, holding Windoze 7, has gone belly-up, and whilst awaiting a recovery disk I'm running Ubunto off USB or DVD as a 'trial'. (And will continue to run Ubuntu after restoring Windoze, as I've rediscovered my love of the penguin :o)) After installing Ubuntu on the stick I ran the software update app, which downloaded some 450Mb of updates and took a couple of hours to install to the stick. A couple of times I got a message saying that disk space was short. So I looked in the file manager (or whatever it's called these days) and couldn't see the stick listed, just: SYSTEM hard disk (listed as 479Gb Filesystem) two other partitions that had been created by Windoze "4.3GB Filesystem" which when I try to open gives the error "Could not find /cow", and when I try to unmount it tells me I can't because it's not mounted - D'OH!! Edit: screenshot of file manager Edit: screenshot of low disk space warning What I can't see is the USB stick from which I'm running Ubuntu. Where's it gone, anybody know? This is tangentially related to a previous question of mine about system tools, in that I'm trying to get control and knowledge of the system in the newest incarnation of Ubuntu.

2D Tile Collision free movement

- by andrepcg

I'm coding a 3D game for a project using OpenGL and I'm trying to do tile collision on a surface. The surface plane is split into a grid of 64x64 pixels and I can simply check if the (x,y) tile is empty or not. Besides having a grid for collision, there's still free movement inside a tile. For each entity, in the end of the update function I simply increase the position by the velocity: pos.x += v.x; pos.y += v.y; I already have a collision grid created but my collide function is not great, i'm not sure how to handle it. I can check if the collision occurs but the way I handle is terrible. int leftTile = repelBox.x / grid->cellSize; int topTile = repelBox.y / grid->cellSize; int rightTile = (repelBox.x + repelBox.w) / grid->cellSize; int bottomTile = (repelBox.y + repelBox.h) / grid->cellSize; for (int y = topTile; y <= bottomTile; ++y) { for (int x = leftTile; x <= rightTile; ++x) { if (grid->getCell(x, y) == BLOCKED){ Rect colBox = grid->getCellRectXY(x, y); Rect xAxis = Rect(pos.x - 20 / 2.0f, pos.y - 20 / 4.0f, 20, 10); Rect yAxis = Rect(pos.x - 20 / 4.0f, pos.y - 20 / 2.0f, 10, 20); if (colBox.Intersects(xAxis)) v.x *= -1; if (colBox.Intersects(yAxis)) v.y *= -1; } } } If instead of reversing the direction I set it to false then when the entity tries to get away from the wall it's still intersecting the tile and gets stuck on that position. EDIT: I've worked with Flashpunk and it has a great function for movement and collision called moveBy. Are there any simplified implementations out there so I can check them out?

Drive reporting incorrect free space

- by Oli

So I swapped my shiny SATA SSD for an even shinier PCI-E SSD. I run my core OS on the SSD because it's silly-fast. I did this on my old SSD so I created a new EXT4 partition and then just dded the data across (sorry I don't know the exact command I ran anymore) and after reinstalling grub, I booted onto the PCI-E SSD. At first glance everything had worked perfectly and things were running faster than ever. But then I noticed the free disk space on the new, larger drive: it was almost exactly the same as it was on the other disk... A disk that was half its size. So it looks as if I've copied the files across incorrectly and it's copied some of the filesystem metadata along with it. Tools like du and Disk Usage Analyzer come back with the correct figures. Things that look at the partition (and not the files) seem to think the drive is 120GB I've been using this drive for a week now so it's way out of sync with the old SSD so dumping the data and starting again isn't a job that fills me with joy but two questions: Is there a way to fix my filesystem so it knows what it's really on about? fsck e2fsck and badblocks all seem to be able to scan it without finding a problem with it. If I do plug my old SSD back in, copy the data off my PCI-E on to it and then copy it back onto a fresh filesystem (eg juggle the data around), what's the best way of doing that? I obviously want to keep all the permissions and softlinks where they are.

Extracting useful information from free text

- by insta

We filter and analyse seats for events. Apparently writing a domain query language for the floor people isn't an option. I'm using C# 4.0 & .NET 4.0, and have relatively free reign to use whatever open-source tools are available. </background-info> If a request comes in for "FLOOR B", the sales people want it to show up if they've entered "FLOOR A-FLOOR F" in a filter. The only problem I have is that there's absolutely no structure to the parsed parameters. I get the string already concatenated (it actually uses a tilde instead of dash). Examples I've seen so far with matches after each: 101WC-199WC (needs to match 150WC) AAA-ZZZ (needs to match AAA, BBB, ABC but not BB) LOGE15-LOGE20 (needs to match LOGE15 but not LOGE150) At first I wanted to try just stripping off the numeric part of the lower and upper, and then incrementing through that. The problem I have is that only some entries have numbers, sometimes the numbers AND letters increment, sometimes its all letters that increment. Since I can't impose any kind of grammar to use (I really wanted [..] expansion syntax), I'm stuck using these entries. Are there any suggestions for how to approach this parsing problem?

Free movement in a tile-based isometric game

- by xtr486

Is there a reasonable easy way to implement free movement in a tile-based isometric game? Meaning that the player wouldn't just instantly jump from one tile to another or not be "snapped" to the grid (for example, if the movement between tiles were animated but you'd be locked from doing anything before the animation finishes). I'm a really beginner with anything related to game programming, but with the help of this site and some other resources it was quite easy to do the basic stuff, but I haven't been able to find any useful resources for this particular problem. Currently I've improvised something close to this: http://jsfiddle.net/KwW5b/4/ (WASD movement). The idea for the movement was to use the mouse map to detect when the player has moved to a different tile and then flip the offsets, and for the most part it works correctly (each corner makes the player move to wrong location: see http://www.youtube.com/watch?v=0xr15IaOhrI, which is probably because I couldn't get the full mouse map work properly), but I have no illusions that it is even close to a good/sane solution. And anyway, it's mostly just to demonstrate what kind of a thing I'd like to implement.

For Australian audiences, would an uncached .com.au domain resolve faster than an uncached .com?

- by thomasrutter

Is there any speed benefit to using a .com.au domain rather than a .com if your customers, hosting and DNS services are in Australia, specifically in the worst typical case (domain is not cached in any local DNS relay for customer)? Assuming that both domains pointed to the same nameservers in the end. I know this is mostly academic because we are talking about a DNS lookup that would take at most a few hundred milliseconds and would only be relevant once at the beginning of a session. I just was curious. I know that an uncached .com lookup will involve consulting at least one ?.gtld-servers.net. server and an uncached .com.au will involve consulting at least one ?.au. server. Now, what I guess I'd need to know is Are the various ?.gtld-servers.net. servers using anycast technology that would have local fully authoritative nodes in Australia, making them just as fast to Australians as ?.au. and avoiding a 200ms+ overseas latency, or are some or all of them hosted only in the US or in the northern hemisphere?

Some Can reach bidmail.com others can't.

- by user69426

On a windows 7 Professional machine in Chrome one of our Estimating assistants can't get to www.bidmail.com, however the other 3 can. On his machine I did nslookup then bidmail.com and it fails to find it. I then went to a machine that could reach bidmail and did nslookup. It can't find it. I was skeptical and thought maybe it was a cached page so I cleared the cache then went back to bidmail.com was able to get to the page, login, lookup a newly posted bid then download the file. Yet I can not look it up through nslookup and I can't ping it www.bidmail.com and I can't trace it. I remoted to our other warehouse which is set up as a workgroup and attempt to nslookup bidmail and that nslookup fail... and on that machine which has never been to bidmail before it was able to connect to the website! I am totally confused if I can't ping it and I can't use nslookup to get there how in the hell is Chrome getting to the page and how do I get this guy back on? Also while typing this I took a new laptop out of the box plugged it in with no updates and can get to bidmail! omg!

How to set up a PRIVATE vimwiki on Dropbox.com

- by Zongheng Yang

Hi everyone, I assume those who are reading this page know what vimwiki and dropbox.com are and what they are for, so I might directly go into my confusion. The common way of setting a PRIVATE vimwiki on dropbox is simply let your vimwiki directories be under Dropbox folder (but not Dropbox/Public/ because it would be PUBLIC). Dropbox allows directly viewing html with dropbox.com/* url: for example a index.html can be accessed by url https://dl-web.dropbox.com/get/Wiki/html/index.html?w=bfead71a, being added after the file name a specified string, ?w=bfead71a. Hence, if inside index.html there is reference to A.html, which is located in the same folder index.html is in, it has to be accessed using some url like https://dl-web.dropbox.com/get/Wiki/html/index.html?w=SPECIFIED_STRING. But it is seemingly impossible to hack vimwiki in order to make the hrefs in converted htmls corrected in this way. Is there some approach that can resolve this problem? I hope I make myself clear. Had you any questions, please ask me for further explanations. Thank you!

When I type mailq on my server, I get: BB523653A62 4025 Wed Jun 4 10:40:07 MAILER-DAEMON (delivery temporarily suspended: host p3smtpout.secureserver.net[208.109.80.54] refused to talk to me: 554 p3plsmtpout002.prod.phx3.secureserver.net : DED : AJeb1o0334uf1Y801 : DED : You've reached your daily relay quota - IP.ADDRESS) hostmaster@MYDOMAIN.COM B33AD653A4A 4025 Wed Jun 4 08:20:07 MAILER-DAEMON (delivery temporarily suspended: host p3smtpout.secureserver.net[208.109.80.54] refused to talk to me: 554 p3plsmtpout002.prod.phx3.secureserver.net : DED : AJeb1o0334uf1Y801 : DED : You've reached your daily relay quota - IP.ADDRESS) hostmaster@MYDOMAIN.COM B77DF653A63 4025 Wed Jun 4 10:50:07 MAILER-DAEMON (delivery temporarily suspended: host p3smtpout.secureserver.net[208.109.80.54] refused to talk to me: 554 p3plsmtpout001.prod.phx3.secureserver.net : DED : AJvF1o00L4uf1Y801 : DED : You've reached your daily relay quota - IP.ADDRESS) hostmaster@MYDOMAIN.COM B943C653A3C 4025 Wed Jun 4 06:40:07 MAILER-DAEMON (delivery temporarily suspended: host p3smtpout.secureserver.net[208.109.80.54] refused to talk to me: 554 p3plsmtpout001.prod.phx3.secureserver.net : DED : AKBv1o00P4uf1Y801 : DED : You've reached your daily relay quota - IP.ADDRESS) hostmaster@MYDOMAIN.COM (there is probably about 50 of these, and I've cleared the queue today), do you know where these could be coming from ? is it my server sending some logs to "hostmaster" ? I've replaced my actual domain, with "MYDOMAIN". How can I find what could be sending these emails ? The server has recently been hacked so I'm also a bit worried. Thanks!

SQL SERVER – Free eBook Download – EPUB, MOBI, PDF Format

- by pinaldave

Microsoft has released recently free eBooks on various Microsoft Technology. The best part is that all these books are available in ePub, Mobi and PDF. You can download them to your local machine or eBook reader and read them. This is a great start as many important subjects are now covered and converted into an eBook. I personally read through a few of the books and found they are very comprehensive and and detailed. The goal is not to cover complete technology in a single book but rather pick a single topic and discuss it in detail. The source of the book is white paper, Technet wiki as well book online and it is clearly listed right bellow the book title. Following are the books available for SQL Server Technology and I encourage all of you to have a look at them as they are great resources. Master Data Services Capacity Guidelines Microsoft SQL Server AlwaysOn Solutions Guide for High Availability and Disaster Recovery Microsoft SQL Server Analysis Services Multidimensional Performance and Operations Guide QuickStart: Learn DAX Basics in 30 Minutes SQL Server 2012 Transact-SQL DML Reference You can download above eBooks from here. This is indeed a great attempt as each book talks about the a single subject in depth keeping author focus on the single and simple subject. I have previously written two books by focusing on the same subject and I had great pleasure writing it as well. Writing on focus subjects gives complete freedom to author to explore the a single subject without having burden to cover everything which is associated with that technology at large. Just like eBooks mentioned earlier my SQL Server Wait Stats was inspired from my article series on SQL Wait Stats. The latest book SQL Server Interview Question and Answers was derived from my article series on SQL Interview Q and A. Writing book is an absolutely different concept than writing blog posts. When I was converting my blog posts to books, I ended up writing 50% new material and end up removing many repetitive content which shows up in blog series. It was indeed fun to focused book at the same time it was a great learning experience as an individual.
