• PHP exec() hangs, Error 500

  - by MRX_II

  So, my plan is to make small thumbnails of URL's with PHP and IECapt. IECapt works well, a nice command line tool, gets the full sized image of specified URL in 1 to 4 seconds. But my problem is to execute it trough PHP. This is the code I've trying to get working: exec('IECapt.exe ' . escapeshellarg($URL) . ' ' . escapeshellarg($Filename)) $URL is of course the URL, and $filename is a simplified version of the URL. Sometimes I get the IECapt to snap the image(trough PHP), but it takes awfully long (30-60s), and in the end I always get a 500-error, with no error messages to tell me what's wrong. Both variables are fine, they work manually with commandline: IECapt http://google.com Google.png My server set-up is IIS7 and PHP5.2.9, if relevant. (Windows Vista, all on my personal computer, so full access.) Any ideas?

• PHP class that changes an image and reloads the page not displaying new image in Internet Explorer

  - by Stuart

  I have a class that runs a function when the image is clicked on to display an additional image. This function produces a linked div tag that reloads the page with a set of variables that then produces another image. The image is set as a background image on a large div tag behind the linked div tags to give the same effect as an image map but without using an image map or a SVG. This works perfectly in Chrome and Firefox but will not display the new image in Internet Explorer until you F5 the page again with the get variables in the URL? Does anyone know how to fix this issue so that it works in IE the same as the other browsers? Many thanks.

• MapView without Zoom Levels Android

  - by RyanInBinary

  I'm using the MapView object for my app and it's working really well. But I noticed that it "locks" to zoom levels, even if you don't use them. For instance, if you pinch to zoom and barely do it, the view will "snap" either forward or backward to whatever the closest zoom level is. The native google maps application does not do this at all. You can barely pinch, and it'll accept it (there are no 'hard' zoom levels built in). How can I get my mapview to mirror that?

• Breaking One Big Graphic of MutablePaths into CAShapeLayers

  - by StackOverFlowRider

  I have a class called GraphicView that takes a Graphic object and draws it in its drawRect method. This Graphic object is basically an array of mutablePaths that comprise an icon that I want drawn. For performance and other issues, I was thinking of taking this icon that is comprised of mutablePaths, and dividing it into a bunch of CAShapeLayers. I'm wondering is this possible? Considering the points for the mutablePaths of the icon are all interwoven together (ie the icon was initially an SVG file that I converted to code), is it possible to divide different parts of the icon into CAShapeLayers, and reassemble them all together when assigning to the views layer? If so how would it be done? If I assign them as sublayers to a CALayer or CAShapeLayer, will it understand to mesh them all together?

• Looking for Your Next Challenge...Don't Stretch Too Far

  - by david.talamelli

  In my role as a Recruiter at Oracle I receive a large number of resumes of people who are interested in working with us. People contact me for a number of reasons, it can be about a specific role that we may be hiring for or they may send me an email asking if there are any suitable roles for them. Sometimes when I speak to people we have similar roles available to the roles that they may actually be in now. Sometimes people are interested in making this type of sideways move if their motivation to change jobs is not necessarily that they are looking for increased responsibility or career advancement (example: money, redundancy, work environment). However there are times when after walking through a specific role with a candidate that they may say to me - "You know that is very similar to the role that I am doing now. I would not want to move unless my next role presents me with the next challenge in my career". This is a far statement - if a person is looking to change jobs for the next step in their career they should be looking at suitable opportunities that will address their need. In this instance a sideways step will not really present any new challenges or responsibilities. The main change would be the company they are working for. Candidates looking for a new role because they are looking to move up the ladder should be looking for a role that offers them the next level of responsibility. I think the best job changes for people who are looking for career advancement are the roles that stretch someone outside of their comfort zone but do not stretch them so much that they can't cope with the added responsibilities and pressure. In my head I often think of this example in the same context of an elastic band - you can stretch it, but only so much before it snaps. That is what you should be looking for - to be stretched but not so much that you snap. If you are for example in an individual contributor role and would like to move into a management role - you may not be quite ready to take on a role that is managing a large workforce or requires significant people management experience. While your intentions may be right, your lack of management experience may fit you outside of the scope of search to be successful this type of role. In this example you can move from an individual contributor role to a management role but it may need to be managing a smaller team rather than a larger team. While you are trying to make this transition you can try to pick up some responsibilities in your current role that would give you the skills and experience you need for your next role. Never be afraid to put your hand up to help on a new project or piece of work. You never know when that newly gained experience may come in handy in your career.

• Transparent Technology from Amazon

  - by David Dorf

  Amazon has been making some interesting moves again, this time in the augmented humanity area.  Augmented humanity is about helping humans overcome their shortcomings using technology.  Putting a powerful smartphone in your pocket helps you in many ways like navigating streets, communicating with far off friends, and accessing information.  But the interface for smartphones is somewhat limiting and unnatural, so companies have been looking for ways to make the technology more transparent and therefore easier to use. When Apple helped us drop the stylus, we took a giant leap forward in simplicity.  Using touchscreens with intuitive gestures was part of the iPhone's original appeal.  People don't want to know that technology is there -- they just want the benefits.  So what's the next leap beyond the touchscreen to make smartphones even easier to use? Two natural ways we interact with the world around us is by using sight and voice.  Google and Apple have been using both in their mobile platforms for limited uses cases.  Nobody actually wants to type a text message, so why not just speak it?  Any if you want more information about a book, why not just snap a picture of the cover?  That's much more accurate than trying to key the title and/or author. So what's Amazon been doing?  First, Amazon released a new iPhone app called Flow that allows iPhone users to see information about products in context.  Yes, its an augmented reality app that uses the phone's camera to view products, and overlays data about the products on the screen.  For the most part it requires the barcode to be visible to correctly identify the product, but I believe it can also recognize certain logos as well.  Download the app and try it out but don't expect perfection.  Its good enough to demonstrate the concept, but its far from accurate enough.  (MobileBeat did a pretty good review.)  Extrapolate to the future and we might just have a heads-up display in our eyeglasses. The second interesting area is voice response, for which Siri is getting lots of attention.  Amazon may have purchased a voice recognition company called Yap, although the deal is not confirmed.  But it would make perfect sense, especially with the Kindle Fire in Amazon's lineup. I believe over the next 3-5 years the way in which we interact with smartphones will mature, and they will become more transparent yet more important to our daily lives.  This will, of course, impact the way we shop, making information more readily accessible than it already is.  Amazon seems to be positioning itself to be at the forefront of this trend, so we should be watching them carefully.

• Overload Avoidance

  - by mikef

  A little under a year ago, Matt Simmons wrote a rather reflective article about his terrifying brush with stress-induced ill health. SysAdmins and DBAs have always been prime victims of work-related stress, but I wonder if that predilection is perhaps getting worse, despite the best efforts of Matt and his trusty side-kick, HR. The constant pressure from share-holders and CFOs to 'streamline' the workforce is partially to blame, but the more recent culprit is technology itself. I can't deny that the rise of technologies like virtualization, PowerCLI, PowerShell, and a host of others has been a tremendous boon. As a result, individual IT professionals are now able to handle more and more tasks and manage increasingly large and complex environments. But, without a doubt, this is a two-edged sword; The reward for competence is invariably more work. Unfortunately, SysAdmins play such a pivotal role in modern business that it's easy to see how they can very quickly become swamped in conflicting demands coming from different directions. However, that doesn't justify the ridiculous hours many are asked (or volunteer) to devote to their work. Admirably though their commitment is, it isn't healthy for them, it sets a dangerous expectation, and eventually something will snap. There are times when everyone needs to step up to the plate outside of 'normal' work hours, but that time isn't all the time. Naturally, with all that lovely technology, you can automate more and more of those tricky tasks to keep on top of the workload, but you are still only human. Clever though you may be, there is a very real limit to how far technology can take you. I'm not suggesting that you avoid these technologies, or deliberately aim for mediocrity; I'm just saying that you need to be more than just technically skilled (and Wesley Nonapeptide riffs on and around this topic in his excellent 'Telepathic Robot Drones' blog post). You need to be able to manage expectations, not just Exchange. Specifically, that means your own expectations of what you are capable of, because those come before everyone else's. After all, how can you keep your work-life balance under control, if you're the one setting the bar way too high? Talking to your manager, or discussing issues with your users, is only going to be productive if you have some facts to work with. "Know Thyself" is the first law of managing work overload, and this is obviously a skill which people develop over time; the fact that veteran Sysadmins exist at all is testament to this. I'd just love to know how you get to that point. Personally, I'm using RescueTime to keep myself honest, but I'm open to recommendations for better methods. Do you track your own time, do you have an intuitive sense of what is possible, or do you just rely on someone else to handle that all for you? Cheers, Michael

• Viewing at Impossible Angles

  - by kemer

  The picture of the little screwdriver with the Allen wrench head to the right is bound to invoke a little nostalgia for those readers who were Sun customers in the late 80s. This tool was a very popular give-away: it was essential for installing and removing Multibus (you youngsters will have to look that up on Wikipedia…) cards in our systems. Back then our mid-sized systems were gargantuan: it was routine for us to schlep around a 200 lb. desk side box and 90 lb. monitor to demo a piece of software your smart phone will run better today. We were very close to the hardware, and the first thing a new field sales systems engineer had to learn was how put together a system. If you were lucky, a grizzled service engineer might run you through the process once, then threaten your health and existence should you ever screw it up so that he had to fix it. Nowadays we make it much easier to learn the ins and outs of our hardware with simulations–3D animations–that take you through the process of putting together or replacing pieces of a system. Most recently, we have posted three sophisticated PDFs that take advantage of Acrobat 9 features to provide a really intelligent approach to documenting hardware installation and repair: Sun Fire X4800/X4800 M2 Animations for Chassis Components Sun Fire X4800/X4800 M2 Animations for Sub Assembly Module (SAM) Sun Fire X4800/X4800 M2 Animations for CMOD Download one of these documents and take a close look at it. You can view the hardware from any angle, including impossible ones. Each document has a number of procedures, that break down into steps. Click on a procedure, then a step and you will see it animated in the drawing. Of course hardware design has generally eliminated the need for things like our old giveaway tools: components snap and lock in. Often you can replace redundant units while the system is hot, but for heaven’s sake, you’ll want to verify that you can do that before you try it! Meanwhile, we can all look forward to a growing portfolio of these intelligent documents. We would love to hear what you think about them. –Kemer

• Why a graduate program in South Africa?

  - by anca.rosu

  South Africa, like many other countries, is desperate for skills. Good, solid, technical skills – together with a get-up-and-go attitude – and the desire to work for a world-class organization that is leading the way! In addition, we have made a commitment in South Africa that we need to transform our organization and develop and empower Black individuals who historically have not had the opportunity to participate in the global economy. It is through this investment in our country's people that we contribute to the development of a nation capable of competing on the global stage. This makes for an exciting recipe! We have: Plenty of young and talented individuals who are eager to get stuck in and learn. Formal, recognized qualifications that form the basis for further development. A huge big global organization – Oracle – that is committed to developing these graduates and giving them an opportunity that is out of this world! Mix the above ‘ingredients’ together Tackle and remove potential “lumps & bumps” along the way as we learn and grow together Nurture and care for each other in a warm but tough environment What have we achieved? In most cases, the outcome is an awesome bunch of new talent that is well equipped to face the IT world. Where we have the opportunity and suitable headcount available to employ these graduates at Oracle we snap them up – alternatively our business partners and customers are always eager to recruit Oracle graduates into their organizations! These individuals go through real-life work place experience whilst at Oracle. In some cases they get to travel internationally. The excitement and buzz gets into their system and their blood becomes truly RED! Oracle RED! This is valuable talent and expertise to have in our eco-system and it’s an exciting program to be a part of not only as a graduate but as an Oracle employee too!   If you have any questions related to this article feel free to contact  [email protected].  You can find our job opportunities via http://campus.oracle.com.

• MSFT new trick to promote IE9 by kill IE6 first.

  - by anirudha

  Every developer know every issue on development for IE6 whenever they know things more. they are frustrated whenever they spent time in IE6 for making application cross browser compatible. not long time ago MSFT make a campaign save IE6 you can find the reference http://blogs.msdn.com/b/anna/archive/2009/04/01/save-internet-explorer-6.aspx and the webstite is here http://www.saveie6.com/ well they really make joke see what they write on the page. well why website maked in PHP whenever they can make them in asp.net or any other technology who reflect the Microsoft technology see here  http://www.saveie6.com/compare.php High security (many updates) :- you can find IE6 is how much secure you can also read Wikipedia for know. well i can say IE6 is very easily to hack. wikipedia tell you about that here http://en.wikipedia.org/wiki/Internet_Explorer_6 and for know about the security watch here http://www.google.co.in/webhp?hl=en#sclient=psy&hl=en&site=webhp&q=ie6+security+issues Lightweight (no support for silly PNG transparency, etc) :- well they tell PNG silly but tell me about the best format on internet. their is no better option as png or SVG. More screen space thanks to no tabs:-  they tell this nonsense without think anything. if they really care about more screen space why they make tab  in 7,8,9. conclusion:- IE team make a research on how to promote IE9 better then they can beat chrome and Firefox. because IE9 not have anything good like customization , plug-in ,add-ons , personas , themes and many other thing like chrome and Firefox provided perhaps IE is outdated thing even everyone their can writing about these days that IE9 have this, have performance better then this… the main problem in IE is IE6. many developer hate them because many of their time goes for making site cross browser compatible. in 2009 they still have no blah like IE9 who they have today so they make a campaign for save IE6. the list they make is a joke. they show that everything in IE6 is perfect even everyone know the truth. they listed IE6 is high security. in 2011 their is a problem for IE9 promotion called IE6. because developer hate IE6 how they can promote IE9 very well. so destroy IE6 is only option for IE9 make promote better. so you can see they make two different different campaign and both are opposite of other. well  how we can believe in IE9. thanks for reading this post. what you thinking on it. have a idea or feedback reported them.

• Exchange 2010, Exchange 2003 Mail Flow issue

  - by Ryan Roussel

  While performing the initial Exchange 2010 deployment for a customer migrating from Exchange 2003, I ran into an issue with mail flow between the two environments.  The Exchange 2003 mailboxes could send to Exchange 2010, as well as to and from the internet.  Exchange 2010 mailboxes could send and receive to the internet, however they could not send to Exchange 2003 mailboxes.   After scouring the internet for a solution, it seemed quite a few people were experiencing this issue with no resolution to be found, or at least not easily.  After many attempts of manually deleting and recreating the routing group connectors,  I finally lucked onto the answer in an obscure comment left to another blogger.   If inheritable permissions are not allowed on the Exchange 2003 object in the Active Directory schema, exchange server authentication cannot be achieved between the servers.   It seems when Blackberry Enterprise Server gets added to 2003 environments, a lot of Admins get tricky and add the BES Admin user explicitly to the server object  to allow  inheritance down from there to all mailboxes.  The problem is they also coincidently turn off inheritance to the server object itself from its parent containers.  You can re-establish inheritance without overwriting the existing ACL however so that the BES Admin can remain in the server object ACL.   By re-establishing inheritance to the 2003 server object, mail flow was instantly restored between the servers.    To re-establish inheritance: 1. Open ASDIedit by adding the snap-in to a MMC (should be included on your 2008 server where Exchange 2010 is installed) 2. Navigate to Configuration > Services > Microsoft Exchange > Exchange Organization > Administrative Groups > First Administrative Group > Servers 3. In the right pane, right click on the CN=Server Name of your Exchange 2003 Server, select properties 4. Navigate to the Security tab, hit advanced toward the bottom. 5. Check the checkbox that reads “include inheritable permissions” toward the bottom of the dialogue box.

• Windows 8 and the future of Silverlight

  - by Laila

  After Steve Ballmer's indiscrete 'MisSpeak' about Windows 8, there has been a lot of speculation about the new operating system. We've now had a few glimpses, such as the demonstration of 'Mosh' at the D9 2011 conference, and the Youtube video, which showed a touch-centric new interface for apps built using HTML5 and JavaScript. This has caused acute anxiety to the programmers who have followed the recommended route of WPF, Silverlight and .NET, but it need not have caused quite so much panic since it was, in fact, just a thin layer to make Windows into an apparently mobile-friendly OS. More worryingly, the press-release from Microsoft was at pains to say that 'Windows 8 apps use the power of HTML5, tapping into the native capabilities of Windows using standard JavaScript and HTML', as if all thought of Silverlight, dominant in WP7, had been jettisoned. Ironically, this brave new 'happening' platform can all be done now in Windows 7 and an iPad, using Adobe Air, so it is hardly cutting-edge; in fact the tile interface had a sort of Retro-Zune Metro UI feel first seen in Media Centre, followed by Windows Phone 7, with any originality leached out of it by the corporate decision-making process. It was kinda weird seeing old Excel running alongside stodgily away amongst all the extreme paragliding videos. The ability to snap and resize concurrent apps might be a novelty on a tablet, but it is hardly so on a PC. It was at that moment that it struck me that here was a spreadsheet application that hadn't even made the leap to the .NET platform. Windows was once again trying to be all things to all men, whereas Apple had carefully separated Mac OS X development from iOS. The acrobatic feat of straddling all mobile and desktop devices with one OS is looking increasingly implausible. There is a world of difference between an operating system that facilitates business procedures and a one that drives a device for playing pop videos and your holiday photos. So where does this leave Silverlight? Pretty much where it was. Windows 8 will support it, and it will continue to be developed, but if these press-releases reflect the thinking within Microsoft, it is no longer seen as the strategic direction. However, Silverlight is still there and there will be a whole new set of developer APIs for building touch-centric apps. Jupiter, for example, is rumoured to involve an App store that provides new, Silverlight based "immersive" applications that are deployed as AppX packages. When the smoke clears, one suspects that the Javascript/HTML5 is merely an alternative development environment for Windows 8 to attract the legions of independent developers outside the .NET culture who are unlikely to ever take a shine to a more serious development environment such as WPF or Silverlight. Cheers, Laila

• Is my work on a developer test being taken advantage of?

  - by CodeWarrior

  I am looking for a job and have applied to a number of positions. One of them responded, I had a pretty lengthy phone interview (perhaps an hour +) and they then set me up with a developer test. I was told that this test is estimated to take between 6 and 8 hours and that, provided it met with their approval, I could be paid for my work on it. That gave me some pause, but I endeavored. The developer test took place on a VM accessed via RDP. The task was to implement a search page in a web project that requests data from the server, displays it on the screen in a table, has a pretty complicated search filtering scheme (there are about 15 statuses and when sending the search to the server you can search by these statuses) in addition to the string/field search. They want some SVG icons to change color on certain data values, they want some data to be represented differently than how it is in the database, etc. Loooong story short, this took one heck of a lot longer than 6-8 hours. Much of it was due to the very poor VM that I was running on (Visual Studio 2013 took 10 minutes to load, and another 15 minutes to open the 3 GB ginormous solution). After completing, I was told to commit my changes to source control... Hmm, OK. I get an email back that they thought that the SVGs could have their color changed differently, they found a bug in this edge-case, there was an occasional problem with this other thing that I never experienced, etc. So I am 13-14 hours into this thing now, and I have to do bug fixes. I do them, and they come back with some more. This is all apparently going into a production application. I noticed some anomalies in the code that was already in there where it looked like other people had coded all of one functionality and not anything else that I could find. Am I just being used for cheap labor? Even if they pay me the promised 50 dollars and hour for 6 hours, I have committed like 18 hours to this thing now. If I bug fix all of the stuff they keep coming up with, I will have worked at least 16 hours for free. I have taken a number of developer tests. I have never taken one where I worked on code that was destined for production. I have never taken one where I implemented a feature that was in the pipeline for development (it was planned for, and I implemented it through the course of the test). And I have never taken one that took 4 rounds and a total of 20+ hours. I get the impression that they are using their developer test to field some of the functionality, that they don't have time for in their normal team, on the cheap. Also, I wouldn't mind a 'devtest' tag.

• I need help with specific types of movement.

  - by IronGiraffe

  I'm adding movable crates to my game and I need some help with my movement code. The way I've set up my movement code the crate's X and Y are moved according to a vector2 unless it hits a wall. Here's the movement code: if (frameCount % (delay / 2) == 0) { for (int i = 0; i < Math.Abs(cSpeed.X); i++) { if (!Level.PlayerHit(new Rectangle(crateBounds.X + (Math.Sign(cSpeed.X) * 32), crateBounds.Y, crateBounds.Width, crateBounds.Height))) { if (!Level.CollideTiles(crateBounds.X + (Math.Sign(cSpeed.X) * 32), crateBounds.Y, crateBounds.Width, crateBounds.Height)) { if (cSpeed.X != 0) { crateBounds.X += Math.Sign(cSpeed.X); } else { Equalize(2); } } else { cSpeed.X = 0f; } } else { if (!Level.CollideTiles(crateBounds.X - (Math.Sign(cSpeed.X) * 32), crateBounds.Y, crateBounds.Width, crateBounds.Height)) { if (cSpeed.X != 0) { crateBounds.X -= Math.Sign(cSpeed.X); } else { Equalize(2); } } else { cSpeed.X = 0f; } } } for (int i = 0; i < Math.Abs(cSpeed.Y); i++) { if (!Level.PlayerHit(new Rectangle(crateBounds.X, crateBounds.Y + Math.Sign(cSpeed.Y), crateBounds.Width, crateBounds.Height))) { if (!Level.CollideTiles(crateBounds.X, crateBounds.Y + Math.Sign(cSpeed.Y), crateBounds.Width, crateBounds.Height)) { crateBounds.Y += Math.Sign(cSpeed.Y); } else { cSpeed.Y = 0f; } } else { if (!Level.CollideTiles(crateBounds.X, crateBounds.Y - Math.Sign(cSpeed.Y), crateBounds.Width, crateBounds.Height)) { crateBounds.Y -= Math.Sign(cSpeed.Y); } else { cSpeed.Y = 0f; } } } } The frameCount and delay variables just slow down the movement somewhat. Anyway, I've added a tool to my game that acts as a gravity well (drawing objects into it's center; the closer they get to the center the faster they go) and what I'm trying to do is make it so that the crate will bounce off the player (and vice versa) when they collide. Thus far, my code only keeps the crate and player from getting stuck inside each other (the player can still get stuck under the crate, but I'll fix that later.) So what I'd like to know is how I can best make the crate bounce off the player. The other movement problem I'm having is related to another tool which allows the player to pick up crates and move around with them. The problem is that the crate's movement while being carried isn't tied to the movement script (it moves the crate itself, instead of adding to speed), which makes the crate go through walls and such. I know what I have to do: make the crate's speed match the player's speed while the player is holding it, but I need the crate to snap to a certain position (just in front of the player) when the player grabs it and it needs to switch to another position (just in front of the player on the other side) when they player faces the other direction while holding it. What would be the best way to make it switch places while keeping all the movement tied to the speed vector?

• Movement prediction for non-shooters

  - by ShadowChaser

  I'm working on an isometric (2D) game with moderate-scale multiplayer - 20-30 players. I've had some difficulty getting a good movement prediction implementation in place. Right now, clients are authoritative for their own position. The server performs validation and broad-scale cheat detection, and I fully realize that the system will never be fully robust against cheating. However, the performance and implementation tradeoffs work well for me right now. Given that I'm dealing with sprite graphics, the game has 8 defined directions rather than free movement. Whenever the player changes their direction or speed (walk, run, stop), a "true" 3D velocity is set on the entity and a packet it sent to the server with the new movement state. In addition, every 250ms additional packets are transmitted with the player's current position for state updates on the server as well as for client prediction. After the server validates the packet, it gets automatically distributed to all of the other "nearby" players. Client-side, all entities with non-zero velocity (ie/ moving entities) are tracked and updated by a rudimentary "physics" system - basically nothing more than changing the position by the velocity according to the elapsed time slice (40ms or so). What I'm struggling with is how to implement clean movement prediction. I have the nagging suspicion that I've made a design mistake somewhere. I've been over the Unreal, Half-life, and all other movement prediction/lag compensation articles I could find, but they all seam geared toward shooters: "Don't send each control change, send updates every 120ms, server is authoritative, client predicts, etc". Unfortunately, that style of design won't work well for me - there's no 3D environment so each individual state change is important. 1) Most of the samples I saw tightly couple movement prediction right into the entities themselves. For example, storing the previous state along with the current state. I'd like to avoid that and keep entities with their "current state" only. Is there a better way to handle this? 2) What should happen when the player stops? I can't interpolate to the correct position, since they might need to walk backwards or another strange direction if their position is too far ahead. 3) What should happen when entities collide? If the current player collides with something, the answer is simple - just stop the player from moving. But what happens if two entities take up the same space on the server? What if the local prediction causes a remote entity to collide with the player or another entity - do I stop them as well? If the prediction had the misfortune of sticking them in front of a wall that the player has gone around, the prediction will never be able to compensate and once the error gets to high the entity will snap to the new position.

• Is my work on a developers test being taken advantage of?

  - by CodeWarrior

  I am looking for a job and have applied to a number of positions. One of them responded, I had a pretty lengthy phone interview (perhaps an hour +) and they then set me up with the developers test. I was told that this test is estimated to take between 6 and 8 hours and that, provided it met with their approval, I could be paid for my work on it. That gave me some pause, but I endeavored. The dev test took place on a VM accessed via RDP. The task was to implement a search page in a web project that requests data from the server, displays it on the screen in a table, has a pretty complicated search filtering scheme (there are about 15 statuses and when sending the search to the server you can search by these statuses) in addition to the string/field search. They want some SVG icons to change color on certain data values, they want some data to be represented differently than how it is in the database, etc. Loooong story short, this took one heck of a lot longer than 6-8 hours. Much of it was due to the very poor VM that I was running on (Visual Studio 2013 took 10 minutes to load, and another 15 minutes to open the 3 GB ginormous solution). After completing, I was told to commit my changes to source control... Hmm, OK. I get an email back that they thought that the SVGs could have their color changed differently, they found a bug in this edge-case, there was an occasional problem with this other thing that I never experienced, etc. So I am 13-14 hours into this thing now and I have to do bug fixes. I do them, and they come back with some more. This is all apparently going into a production application. I noticed some anomalies in the code that was already in there where it looked like other people had coded all of one functionality and not anything else that I could find. Am I just being used for cheap labor? Even if they pay me the promised 50 dollars and hour for 6 hours, I have committed like 18 hours to this thing now. If I bug fix all of the stuff they keep coming up with, I will have worked at least 16 hours for free. I have taken a number of dev tests. I have never taken one where I worked on code that was destined for production. I have never taken one where I implemented a feature that was in the pipeline for development (it was planned for, and I implemented it through the course of the test). And I have never taken one that took 4 rounds and a total of 20+ hours. I get the impression that they are using their dev test to field some of the functionality, that they don't have time for in their normal team, on the cheap. Also, I wouldn't mind a 'devtest' tag.

• Powerpoint missing from DCOM config

  - by Paul Prewett

  I have an application that automates the creation of powerpoint files in an ASP.NET environment. This requires that I install powerpoint on the server and also set permissions in the DCOM configuration snap-in (dcomcnfg) to give permissions to the launching user ([DOMAIN]\ASPNET in this case) to run the application. I have this setup running successfully on several Win2k3 machines. I am configuring my first Win2k8 machine and after installing powerpoint on the server, the "Microsoft Powerpoint Presentation" node in DCOM config is not showing up. Other installed Office apps are showing (Excel, Graph, etc...), just not Powerpoint. So when I attempt to run the application, I get an "Access denied" error, which is exactly what I would expect. The user doesn't have permission. Therefore, access denied. The specific error log entry is: The machine-default permission settings do not grant Local Activation permission for the COM Server application with CLSID {91493441-5A91-11CF-8700-00AA0060263B} to the user [DOMAIN]\ASPNET I searched the entire list for the CLSID, too, thinking maybe the name wasn't loading properly. No dice. I also re-ran the setup program for Office thinking maybe there would be some option or something I unchecked in the custom setup options, but I saw nothing that looked helpful. I'm flummoxed. Can anyone out there suggest something to help me get Powerpoint to show up in the list of DCOM applications? Many thanks.

• SChannel "cannot find certificate in either LocalMachine or CurrentUser store"

  - by Chris J

  We have an in-house application that requires the use of client SSL certificates to authenticate with a remote server (not under our control). This has worked without problems before but on deploying to a new server, we're having problems getting Windows 2008 to use the certificate. The certificate exists as a .pfx file that contains a private key. The same certificate exists in the LocalMachine store, again with its private key. We've ensured the one in the LocalMachine store is correct by creating a website in IIS against that certificate, so we're happy that the certificate, certificate chain, and private key is valid. The PFX has been created by exporting from the Certificates MMC snap-in. The issue is that we get the following in the system diagnostic logs that suggests it can't find the private key: System.Net Information: 0 : [5988] SecureChannel#23264094 – Locating the private key for the certificate: [Subject] CN=internal-server.company.com, OU=Servers, OU=Devices, O=org [Issuer] CN=SubCA02, OU=CA, o=org [Serial Number] 407ABCDE [Not Before] 31/10/2013 11:08:48 AM [Not After] 31/10/2016 11:08:48 AM [Thumbprint] 4354A34F6004F019E60F055979A47E50F62D1504 . System.Net Information: 0 : [5988] SecureChannel#23264094 – Cannot find the certificate in either the LocalMachine store or the CurrentUser store. I've validated the thumbprint, issuer and serial number listed in the log with the certificate in the LocalMachine store and these marry up. From what I can tell with much searching, this appears to be a permissions issue. The user the application is running as has been granted access to the private key (Personal Certificates - right click on the certificate - all tasks - Manage Private Keys), so I'm now at a loss as to which permission(s) it may be that is causing the issue.

• HOWTO: Disable complex password policy on Hyper-V Server 2008?

  - by Ian Boyd

  How do you disable the password complexity requirements on a Microsoft Hyper-V Server 2008 R2? Keep in mind that when you log into the server, the only UI you have is: And you cannot run gpedit.msc: C:\Users\Administrator>gpedit.msc 'gpedit.msc' is not recognized as an internal or external command, operable program or batch file. because there are no .msc snap-ins installed with Microsoft Hyper-V Server 2008 R2. The problem comes when you're trying to add an account to the server, so you can manage it, but it doesn't like most passwords: And, predictably, typing NET HELPMSG 2245 gives you The password does not meet the password policy requirements. Check the minimum p assword length, password complexity and password history requirements. i hoped it would have been a friendly user experience, and either: offered to disable the password policy tell me how to disable the password policy tell me how to check the minimum password length, password complexity and password history requirements. Password Complexity Requirements The Microsoft's default password complexity for Server Core is: Passwords cannot contain the user’s account name or parts of the user’s full name that exceed two consecutive characters. Passwords must be at least six characters in length. Passwords must contain characters from three of the following four categories: 1.English uppercase characters (A through Z). 2.English lowercase characters (a through z). 3.Base 10 digits (0 through 9). 4.Non-alphabetic characters (for example, !, $, #, %).

So many people keep coming coming to it: up-vote it!

• ESXi 4.1 host not recognising existing VMFS datastore

  - by Graeme Donaldson

  Existing setup: host1 and host2, ESX 4.0, 2 HBAs each. lun1 and lun2, 2 LUNs belonging to the same RAID set (my terminology might be sketchy here). This has been working just fine all along. I added host3, ESXi 4.1, 2 HBAs. If I view Configuration / Storage Adapters, I can see that both HBAs see both LUNs, but if I view Configuration / Storage, I only see 1 datastore. host1/2 can see both LUNs and I have VMs running on both too. I have rescanned, refreshed and even rebooted, but host3 refuses to acknowledge 1 of the datastores. Does anyone know what's going on? Update: I re-installed the host with ESX (not i) 4.0, same version as the existing hosts and it's still not recognising the vmfs. I think I'm going to SVmotion everything off that datastore then format it. Update2: I've created the LUN from scratch and the problem gets even weirder. I've presented the LUN to all 3 hosts, and I can see the LUN in the vSphere client's Configuration / Storage Adapters section on all 3 hosts. If I create a datastore on the LUN via the Configuration / Storage section on host1, it works fine and I can create an empty folder via datastore browser, but the datastore is not seen by the host2 and host3. I can use the Add Storage wizard on host2 and it will see the LUN. At this point the "VMFS Label" column has the label I gave with "(head)" appended. If I try the Add Storage wizard's "Keep the existing signature" option, it fails with an error "Cannot change the host configuration." and a dialog box that says 'Call "HostStorageSystem.ResolveMultipleUnresolvedVmfsVolumes" for object "storageSystem-17" on vCenter Server "vcenter.company.local" failed.' If I try the Add Storage wizard's "Assign a new signature" option on host2, it will complete and the VMFS label will have "snap-(hexnumber)-" prepended. At this point its also visible on host3, but not host1. I have a similar setup in a different datacenter which didn't give me all this trouble.

• Why can't I delete my depot on Perforce?

  - by teukkam

  I'm just messing around in a local Perforce database, trying to figure out how I can reset Perforce back to a previous state without journaling or deleting and recreating the database files. I have some depots without files, one of them is called "sandbox". I created it with the p4 depot command either from the command line or using the P4Python API (at this point I don't remember which). When I type: p4 depot -d sandbox I get this: Depot sandbox isn't empty. To delete a depot, all file revisions must be removed and all lazy copy references from other depots must be severed. Use 'p4 obliterate' or 'p4 snap' to break file linkages from other depots, then clear this depot with 'p4 obliterate', then retry the deletion. I tried p4 obliterate -y sandbox which just says No records to delete. which is expectable as the depot is empty. Anyway it doesn't change the result from p4 depot -d. There are also no connections from other depots as the error message suggests. Any idea what is happening and is there a foolproof way to force a depot to be deleted without deleting the server files altogether? Ultimately I want to do this automatically from P4Python.
