• A Comparison of Store Layouts

  - by David Dorf

  Belus Capital Advisors is an independent stock market research firm that sometimes rolls up its sleeves and walks retail stores.  This month Brian Sozzi walked both Macy's and Sears and snapped pictures along the way.  The results are a good lesson in what to do and what not to do in retail.  The dichotomy between the two brands is stark, and Brian's pictures tell the stories of artistry and neglect.  For example, look at these two pictures: Where do you want to shop for sneakers?  The left picture shows the Finish Line store within Macy's and the right shows empty shelves at Sears.  The pictures really show the importance of assortments, in-stock inventory, and presentation.  Take a look at the two stories, and pay particular attention to the pictures of Sears. 19 Photos that Show the New Magic of Macy’s Sears is Vanishing from our Minds, the Shocking 18 Photos That Show Why

• Isometric algorithm producing tiles in wrong draw order

  - by David

  I've been toying with isometric and I just cant get the tiles to be in the right order. I'm probably missing something obvious and I just can't see it. Even at the risk of looking stupid, here's my code: for (int i = 0; i < Tile.MapSize; i++) { for (int j = 0; j < Tile.MapSize; j++) { spriteBatch.Draw( Tile.TileSetTexture, new Rectangle( (-j * Tile.TileWidth / 2) + (i * Tile.TileWidth / 2), (i * (Tile.TileHeight - 9) / 2) - (-j * (Tile.TileHeight - 9) / 2), Tile.TileWidth, Tile.TileHeight), Tile.GetSourceRectangle(tileID), Color.White, 0.0f, new Vector2(-350, -60), SpriteEffects.None, 1.0f); } } And here's what I end up with: messed up map Yep, bit of an issue. If anyone could help, I'd appreciate it.

• Cannot copy files from external USB HDD to computer

  - by Thomas Versteeg

  Hello I have a HDD disk connected with a USB converter to my computer. It consists of two partitions, the first one is mounted automatically and I can grab all the files from it, but the second one I have to mount manually as a root in the command line, if I try to open it with nautilus it gives an error. The drive where the problem is is drive sdb1, sdb2 has the same settings but works fine. I am using Debian Wheezy. This is the fstab: /dev/sdb1 /media/usb0 auto defaults,gid=disk,umask=0777 0 0 /dev/sdb2 /media/usb1 auto defaults,gid=disk,umask=0777 0 0 And when I try to copy the files with this command (as root) cp -vr /media/usb0/* /home/user/Videos/ I get these types of errors: cp: reading `/media/usb0/.lang/file.ext': Permission denied cp: failed to extend `/home/user/Videos/.lang/file.ext': Permission denied How can I at least copy the files to my main HDD? I don't need to adjust them I only need to copy them!

• Determining speed (class) of USB on PC

  - by Thomas Matthews

  Is there a method for determining the speed of a USB port on a Windows XP PC, without using a USB protocol analyzer? I'm looking for something simple, such as looking at the Device Manager. I would like to hook up some USB equipment to a USB 2.0 port, rather than the slower USB 1.0 or 1.1.

• Full Backup & Restore for Windows Vista

  - by Thomas Matthews

  I'm looking for a freeware or low cost application that will backup everything, including registry on Windows Vista Home Premium and to restore from a CDROM disk. The destination is an external hard drive on USB 2.0. Searching on SuperUser and Stack Overflow show articles, but don't mention full backup of the registry and complete restore using CDROM. I would also like to have compressed output and incremental backups. One article mentions CloneZilla, but their web page says that the incremental feature is not supported. I am using Windows Vista Home Premium, Service Pack 1. I need to backup 200 GB onto a 230 GB drive and would like to have multiple backups (thus the need for compression). Other requirements: Single file restore Quality is more important than performance. Application must run on Windows Vista. Extra: Run as daemon or background task on 4 user system. Thanks

• How can I make a browser trust my SSL certificate when I request resources from an external server?

  - by William David Edwards

  I have installed an SSL certificate on one of my domains and it works perfectly, but on some pages I include a Google Font, which causes my certificate icon to change in: instead of: The reason, according to Google Chrome (translated with Google Translate): Your connection to xxxxxx is encrypted with 128-bit encryption. This page includes other resources which are not secure. These resources can be viewed by others while in transit and can be modified to fit. So how can I make the browser 'trust' my SSL certificate, even though I request an external resource from Google Fonts? And also, does it matter that I use links like these: <link rel='stylesheet' id='et-shortcodes-css-css' href='https://xxxxxx/wp-content/themes/Divi/epanel/shortcodes/css/shortcodes.css?ver=3.0' type='text/css' media='all' /> instead of <link rel='stylesheet' id='et-shortcodes-css-css' href='wp-content/themes/Divi/epanel/shortcodes/css/shortcodes.css?ver=3.0' type='text/css' media='all' /> Thanks!

• Virtual Grocery Store

  - by David Dorf

  Because South Korean's are so busy, Tesco decided that its Homeplus grocery chain should offer a virtual alternative in subways.  As you can see in the video below, shoppers passing through a subway station can see a virtual representation of the store and scan items with their mobile phones.  This builds a shopping list which is delivered to their homes later that day. This is a very cool example of leveraging technology to offer a shopping experience that's different from bricks and clicks.

• ODI 11g – Faster Files

  - by David Allan

  Deep in the trenches of ODI development I raised my head above the parapet to read a few odds and ends and then think why don’t they know this? Such as this article here – in the past customers (see forum) were told to use a staging route which has a big overhead for large files. This KM is an example of the great extensibility capabilities of ODI, its quite simple, just a new KM that; improves the out of the box experience – just build the mapping and the appropriate KM is used improves out of the box performance for file to file data movement. This improvement for out of the box handling for File to File data integration cases (from the 11.1.1.5.2 companion CD and on) dramatically speeds up the file integration handling. In the past I had seem some consultants write perl versions of the file to file integration case, now Oracle ships this KM to fill the gap. You can find the documentation for the IKM here. The KM uses pure java to perform the integration, using java.io classes to read and write the file in a pipe – it uses java threading in order to super-charge the file processing, and can process several source files at once when the datastore's resource name contains a wildcard. This is a big step for regular file processing on the way to super-charging big data files using Hadoop – the KM works with the lightweight agent and regular filesystems. So in my design below transforming a bunch of files, by default the IKM File to File (Java) knowledge module was assigned. I pointed the KM at my JDK (since the KM generates and compiles java), and I also increased the thread count to 2, to take advantage of my 2 processors. For my illustration I transformed (can also filter if desired) and moved about 1.3Gb with 2 threads in 140 seconds (with a single thread it took 220 seconds) - by no means was this on any super computer by the way. The great thing here is that it worked well out of the box from the design to the execution without any funky configuration, plus, and a big plus it was much faster than before, So if you are doing any file to file transformations, check it out!

• Restoring MSDB

  - by David-Betteridge

  We recently performed a disaster recovery exercise which included the restoration of the MSDB database onto our DR server.  I did a quick google to see if there were any special considerations and found the following MS article.  Considerations for Restoring the model and msdb Databases (http://msdn.microsoft.com/en-us/library/ms190749(v=sql.105).aspx).   It said both the original and replacement servers must be on the same version,  I double-checked and in my case they are both SQL Server 2008 R2 SP1 (10.50.2500).. So I went ahead and stopped SQL Server agent, restored the database and restarted the agent.  Checked the jobs and they were all there, everything looked great, and was until the server was rebooted a few days later.Then the syspolicy_purge_history job started failing on the 3rd step with the error message “Unable to start execution of step 3 (reason: The PowerShell subsystem failed to load [see the SQLAGENT.OUT file for details]; The job has been suspended). The step failed.”   A bit more googling pointed me to the msdb.dbo.syssubsystems table SELECT * FROM msdb.dbo.syssubsystems WHERE start_entry_point ='PowerShellStart'   And in particular the value for the subsystem_dll. It still had the path to the SQLPOWERSHELLSS.DLL but on the old server. The DR instance has a different name to the live instance and so the paths are different.   This was quickly fixed with the following SQL Use msdb; GO sp_configure 'allow updates', 1 ; RECONFIGURE WITH OVERRIDE ; GO UPDATE msdb.dbo.syssubsystems SET subsystem_dll='C:\Program Files\Microsoft SQL Server\MSSQL10_50.DR\MSSQL\binn\SQLPOWERSHELLSS.DLL' WHERE start_entry_point ='PowerShellStart'; GO sp_configure 'allow updates', 0; RECONFIGURE WITH OVERRIDE ; GO Stopped and started SQL Server agent and now the job completes.   I then wondered if anything else might be broken, SELECT subsystem_dll FROM msdb.dbo.syssubsystems Shows a further 10 wrong paths – fortunately for parts of SQL (replication, SSIS etc) we aren’t using! Lessons Learnt 1.       DR exercises are a good thing! 2.       Keep the Live and DR environments as similar as possible.

• Has anyone got the Mist engine to work on gtk3? [closed]

  - by David

  Possible Duplicate: What GTK+ 3 engines are available? I've just upgraded my xubuntu installation to Precise and run into gtk3 theme problems - my theme based on the Mist engine doesn't work for gtk3 apps. There's a package gtk3-engines in the GNOME PPA that includes Mist, has anyone got this to work? It has a themes/Mist/gtk3.0 folder with a gtkrc file but it doesn't seem to work for me. Even if someone just has an idea where I could find more help on this I'd be grateful (is there even any documentation on making themes in gtk3?)

• What do you use to bundle / encrypt data?

  - by David McGraw

  More and more games are going the data driven route which means that there needs to be a layer of security around easy manipulation. I've seen it where games completely bundle up their assets (audio, art, data) and I'm wondering how they are managing that? Are there applications / libraries that will bundle and assist you with managing the assets within? If not is there any good resources that you would point to for packing / unpacking / encryption? This specific question revolves around C++, but I would be open to hear how this is managed in C#/XNA as well. Just to be clear -- I'm not out to engineer a solution to prevent hacking. At the fundamental level we're all manipulating 0's and 1's. But, we do want to keep the 99% of people that play the game from simply modifying XML files that are used to build the game world. I've seen plenty of games bundle all of their resources together. I'm simply curious about the methods they're using.

• Software cost estimation

  - by David Conde

  I've seen on my work place (a University) most students making the software estimation cost of their final diploma work using COCOMO. My guessing is that this way of estimating costs is somewhat old (COCOMO dates of 1981), hence my question: How do you estimate costs in your software? I've seen things like : Cost = ( HoursOfWork + EstimatedIddle ) * HourlyRate That's not what I want, I'm looking for a properly (scientifically) defined cost model EDIT I've found some related questions on SO: What are some of the software cost estimation methods and models? How do you estimate the cost of developing software requirements?

• How to force user to use subdomain?

  - by David Stockinger

  I am hosting a webshop with OpenCart and its current URL is e.g. http://mydomain.com/shop/ I have created two subdomains ( http://pg.mydomain.com/ and http://shop.mydomain.com/ ) and both subdomains are already working as they should. However, can I restrict direct access to mydomain.com/shop/ while leaving all the files (index.php, etc.) there? Since both subdomains are pointing to http://mydomain.com/shop/, I thought this would restrict all access. So in the end, I would like my two shops to be accessable through http://pg.mydomain.com/ and http://shop.mydomain.com/, but not http://mydomain.com/shop/ while leaving all the files in http://mydomain.com/shop/.

• Can I migrate a clone of Google Code repository into Github?

  - by David Conde

  I want to create a clone of a Google Code repository, which I cannot download due to Country restrictions and I want to migrate that clone into Github, which I can use without any problem. The thing is I have a Github account and I can browse through GoogleCode but I cannot take my TortoiseHg and clone a repo just like that because I'm from Cuba and I get a lovely Google page saying that I cannot go into Google code. I'm guessing you know how I manage to browse :) I would like to import a mercurial repository into my Github repo, my questions: Is it possible? How can I do it?

• How exactly does XNA's SpriteBatch work?

  - by David Gouveia

  To be more precise, if I needed to recreate this functionality from scratch in another API (e.g. in OpenGL) what would it need to be capable of doing? I do have a general idea of some of the steps, such as how it prepares an orthographic projection matrix and creates a quad for each draw call. I'm not too familiar, however, with the batching process itself. Are all quads stored in the same vertex buffer? Does it need an index buffer? How are different textures handled? If possible I'd be grateful if you could guide me through the process from when SpriteBatch.Begin() is called until SpriteBatch.End(), at least when using the default Deferred mode.

• Precise Touch Screen Dragging Issue: Trouble Aligning with the Finger due to Different Screen Resolution

  - by David Dimalanta

  Please, I need your help. I'm trying to make a game that will drag-n-drop a sprite/image while my finger follows precisely with the image without being offset. When I'm trying on a 900x1280 (in X [900] and Y [1280]) screen resolution of the Google Nexus 7 tablet, it follows precisely. However, if I try testing on a phone smaller than 900x1280, my finger and the image won't aligned properly and correctly except it still dragging. This is the code I used for making a sprite dragging with my finger under touchDragged(): x = ((screenX + Gdx.input.getX())/2) - (fruit.width/2); y = ((camera_2.viewportHeight * multiplier) - ((screenY + Gdx.input.getY())/2) - (fruit.width/2)); This code above will make the finger and the image/sprite stays together in place while dragging but only works on 900x1280. You'll be wondering there's camera_2.viewportHeight in my code. Here are for two reasons: to prevent inverted drag (e.g. when you swipe with your finger downwards, the sprite moves upward instead) and baseline for reading coordinate...I think. Now when I'm adding another orthographic camera named camera_1 and changing its setting, I recently used it for adjusting the falling object by meter per pixel. Also, it seems effective independently for smartphones that has smaller resolution and this is what I used here: show() camera_1 = new OrthographicCamera(); camera_1.viewportHeight = 280; // --> I set it to a smaller view port height so that the object would fall faster, decreasing the chance of drag force. camera_1.viewportWidth = 196; // --> Make it proportion to the original screen view size as possible. camera_1.position.set(camera_1.viewportWidth * 0.5f, camera_1.viewportHeight * 0.5f, 0f); camera_1.update(); touchDragged() x = ((screenX + (camera_1.viewportWidth/Gdx.input.getX()))/2) - (fruit.width/2); y = ((camera_1.viewportHeight * multiplier) - ((screenY + (camera_1.viewportHeight/Gdx.input.getY()))/2) - (fruit.width/2)); But the result instead of just following the image/sprite closely to my finger, it still has a space/gap between the sprite/image and the finger. It is possibly dependent on coordinates based on the screen resolution. I'm trying to drag the blueberry sprite with my finger. My expectation did not met since I want my finger and the sprite/image (blueberry) to stay close together while dragging until I release it. Here's what it looks like: I got to figure it out how to make independent on all screen sizes by just following the image/sprite closely to my finger while dragging even on most different screen sizes instead.

• Designing Videogame Character Parodies [duplicate]

  - by David Dimalanta

  This question already has an answer here: Is it legal to add a cameo appearance of a known video game character in my game? 2 answers Was it okay to make a playable character when making a videogame despite its resemblance? For example, I'm making a 3rd-person action-platform genre and I have to make a character design resembling like Megaman but not exactly the same as him since there is little alternate in color, details, and facial features.

• Projects to learn web development

  - by David McDavidson

  I'm trying to get a job as a web developer, but the great majority of jobs offers requires previous experience and a portfolio to prove you've got the required skills. Unfortunately I don't have any real experience or anything to show. The best way to learn is to try and tackle real world problems, so I'd like to know what would be some nice projects to learn stuff and that will look good in a portfolio?

• The actual difference between styesheet in the header and a seperate file

  - by David Knight

  Am wondering if someone can give me an opinion on this. I have always been taught to have all of the CSS in a separate file that is referenced from the head of the page. Reading this article http://www.lukew.com/ff/entry.asp?1792 the author is talking about making the Guardian website responsive. One of the things he notes they did to make the site faster and more resilient is to add the CSS inline into the header, thus reducing HTTP requests. Now this got me thinking about the right/best/fastest way of using the CSS If you have one main CSS file, its going to be called and read by the site on every page, no mater how big it is. So with that in mind, Im actually starting to think its better to just inline the whole style sheet and remove one HTTP roundtrip. I know for the purposes of neatness and being able to edit the file a seperate file is better. But which would you recommend and which do you think is faster? Thanks!

• What is the best C++ interview question?

  - by David Thielen

  If you could ask a C++ programmer one question to measure their C++ skills, what would it be? The question I think is best is: Can you call "delete this;" inside a member function? (I put this as a link so you can think it through first, then go to The Best C++ Interview Question – Ever! to see the correct answer.) I don't ask this because I expect most people to know the answer. If they did it would not be that useful a question. I ask to see if they can work their way to the correct answer and how they do so.

• I've created a software RAID on SUSE EL 10 and now I need to monitor it.......

  - by Thomas B.

  I have created a Software Raid using the yast2 GUI on SUSE ES 10/11. The raid works great and it's a raid 5. I have 5 Drives they are cheap 2GB Cases that have 2 - 1TB Drives in each case (Serial ATA Drives) and I connect them in via Esata to the motherboard. The problem I have as this is "cheap" storage when of the the 5 drives goes out on the RAID I seem to have no logs of any issues and it get's harder and harder to write to it until it dies. I use SAMBA to mount the 4TB parition to my PC's in my home on a GIG network. My question is this, are there any good (Free) tools in Linux to monitor a raid or the drives on the raid to detect any problems??? I haven't found any yet and was just wondering if some exist.

• Curiosity on any Smartphones that Run on Android 2.3.3 with Different Screen Reoslution

  - by David Dimalanta

  I have a question regarding about any smartphones that run only in Android 2.3.3. Is the size of screen or the screen resolution is always HVGA or does it have capable of running this OS (Android 2.3.3) on big screen size (4" to 5") at about 720x1280? I'm thinking of the game's compatibility depending on the version of the Android OS and the screen resolution, which affects the change of coordinates especially for assigning touch buttons and drag-n-drop at exact location, before I'm gonna decide to make one. My program works on the Android 4 ICS and Jellybean, however, will that work on Android 2.3.3 in spite of precise touch coordinate or just dependent on the screen resolution (regardless how large it is) as the X and Y coordinate? And take note, I'm using Eclipse IDE for Java developers.
