• Super-silent (mid tower) case and fan combo

  - by Dennis G.

  I want to build a HTPC for music/video/blu-ray playback (no gaming). I don't need an expensive HTPC case but just want to go with a standard medium tower case. However, I want it to be super silent so it doesn't make any annoying fan/disk noises when I watch movies. Ideally, it shouldn't make any noticeable noise at all. I understand that choosing a board, CPU and graphic card that run cool and don't consume a lot of power is important for designing a quiet machine, and I think I got that covered. However, there are so many choices in regards to cases, fans and power supplies that it's hard to get started. What are your recommendations for a case/fan (cpu+case)/power supply combination that run absolutely silent and can cool a standard Intel system with a low-power (possibly passively cooled) graphic card? I'm usually a fan of Antec cases, would an Antec Mini P180 be a good starting point? If so, which case fans, CPU fan and power supply would you recommend?

• Android-Libgdx-ProGuard: Usefulness without DexGuard? [on hold]

  - by Rico Pablo Mince

  So I'm developing a game for Android - using LibGDX - and noticed that the Android SDK (HDK, MDK, WhatTheHellEvarDK) has ProGuard built-in. Browsing the ProGuard page is like searching Google: you get that the idea is to sell some product (in this case, it's DexGuard). That leaves me wondering what features are left out of ProGuard that a game developer targeting Android should worry about. For instance, the ProGuard FAQs answer the question: "Does ProGuard encrypt string constants?" by saying: "No. String encryption in program code has to be perfectly reversible by definition, so it only improves the obfuscation level. It increases the footprint of the code. However, by popular demand, ProGuard's closed-source sibling for Android, DexGuard, does provide string encryption, along with more protection techniques against static and dynamic analysis." Alright. OK. But isn't "...improves the obfuscation level" EXACTLY what ProGuard is supposed to do? Are there better options that can be implemented at build-time in Eclipse using the Gradle options and Libgdx? In particular, the assets folder and res-specific folders will need some protection. The code itself doesn't cure cancer, but I'd prefer if nobody could copy/paste it with different game art and call it "IhAxEdUrGamE"....

• How to mirror filesystems with millions of hardlinks?

  - by Thomas Berger

  We have one big problem at the moment: We need to mirror a filesystem for one of our customers. Thats usual not really a problem, but here it is: On this filesystem there is one folder with millions of hardlinks (yes! MILLIONS!). rsync requires more then 4 days to just build the filelist. We use the following rsync options: rsync -Havz --progress serverA:/data/cms /data/ Has anyone a idea how to speed up this rsync, or use alternatives? We could not use dd as the target disk is smaller then the source.

• Can One Get a Solid Programming Foundation Without Going To College/University?

  - by Daniel

  First, I have already searched the site and read all the previous "self-taught vs. college" topics. The majority of the answers defended that going to college was the best choice, for two main reasons: Going to college gives you the paper, which is essential to landing jobs, especially in tough economic times. Going to college gives you a solid programming base, teaching you the principles that will be essential regardless of the language/path you take after. Here comes my question: I am not worried about reason 1 at all, because I already have my own company (I build websites/ do affiliate marketing) and a stable financial situation, so I am pretty sure I won't need to look around for a job. I am worried about reason 2 though. That is, I want to make sure I'll have as solid a programming foundation as anyone else out there, and I am wondering if that is possible with self-learning. Suppose I take my time to study the very basics, like discrete maths, algorithm design, programming logic, computer architecture, Assembly, C programming, databases and data structures - mostly using books,online resources and lots of coding. Say I spend 1-2 years covering those basics. Do you think my foundation would be solid, or still lack in comparison to someone who went to college?

• How to practice object oriented programming?

  - by user1620696

  I've always programmed in procedural languages and currently I'm moving towards object orientation. The main problem I've faced is that I can't see a way to practice object orientation in an effective way. I'll explain my point. When I've learned PHP and C it was pretty easy to practice: it was just matter of choosing something and thinking about an algorithm for that thing. In PHP for example, it was matter os sitting down and thinking: "well, just to practice, let me build one application with an administration area where people can add products". This was pretty easy, it was matter of thinking of an algorithm to register some user, to login the user, and to add the products. Combining these with PHP features, it was a good way to practice. Now, in object orientation we have lots of additional things. It's not just a matter of thinking about an algorithm, but analysing requirements deeper, writing use cases, figuring out class diagrams, properties and methods, setting up dependency injection and lots of things. The main point is that in the way I've been learning object orientation it seems that a good design is crucial, while in procedural languages one vague idea was enough. I'm not saying that in procedural languages we can write good software without design, just that for sake of practicing it is feasible, while in object orientation it seems not feasible to go without a good design, even for practicing. This seems to be a problem, because if each time I'm going to practice I need to figure out tons of requirements, use cases and so on, it seems to become not a good way to become better at object orientation, because this requires me to have one whole idea for an app everytime I'm going to practice. Because of that, what's a good way to practice object orientation?

• Maintenance Plan Reporting - Append To File - Clean Up?

  - by Adam J.R. Erickson

  Background: (SQL Server 2005, Standard Ed.) I have a maintenance plan running backups, taking a full backup 1/day, and t-log every 15 minutes. I have it set to create a text file report of each run, but that creates A LOT of files on the file server. These are hard to sort through, which makes them less useful. Question: There is an option in "Reporting and Logging" settings for appending all logs together, but how do you clean this out? If you're appending to the same log file every time, how should you make sure this file doesn't grow indefinitely? Is there a build-in function to clean out portions of appended logs like there is for cleaning out individual old log files?

• Bluetooth headset A2DP works, HSP/HFP not (no sound/no mic)

  - by Stefan Armbruster

  My Philips SBH9001 headset pairs fine using Ubuntu 12.04. In the audio settings it's properly detected as A2DP device and as HSP/HFP device. Hardware: Thinkpad X230, Ubuntu 12.04 64bit, Kernel 3.6.0-030600rc3-generic (build from Ubuntu mainline repo), Bluetooth device is USB-Id 0a5c:21e6 from Broadcom, Headset is a Philips SBH9001. Note: Kernel 3.6 rc3 is used because of a fix for audio on the dockingstation that is not in any previous branches. Playing audio in A2DP works just fine out of the box, but when switching the headset to HSP/HSP mode there is no sound nor does the microphone work. When connecting the headset, /var/log/syslog shows: Aug 25 21:32:47 x230 bluetoothd[735]: Badly formated or unrecognized command: AT+CSRSF=1,1,1,1,1,7 Aug 25 21:32:49 x230 rtkit-daemon[1879]: Successfully made thread 17091 of process 14713 (n/a) owned by '1000' RT at priority 5.

• Memory concerns while plotting escape from DLL Hell in Delphi

  - by Peter Turner

  I work on a program with about 50 DLLs that are loaded from one executable, it's an old organically grown program where the only rationale for creating a new DLL is that one previously didn't exist to fill a given need. (and namespaces didn't exist in Delphi so it never crossed our mind to make dll1.main.pas, dll2.main.pas or something even more unique) What we want to do is consolidate all these DLLs into one executable, since none of them are used out of the program, there shouldn't be much of a problem. The concern my boss has is that if we did this, the memory overhead for terminal server clients would go through the roof. So, I've stepped through enough initialization code to know that lots of stuff is done every time a DLL is loaded in to memory, but say I've got a project with about 4000 files, and 50 dlls, 10 of which are probably utilized by any one user in any one session of the program. The 50 dlls are about 2/3rds form files, if not more, but beyond that there's not a lot of other resources being loaded (only a few embedded pictures, icons, cursors, etc..). If I loaded all these files in to memory, how much memory is used per unit? how much is used per class? How do I keep the overhead down? and what is the biggest project one can reasonably expect to build with Delphi? This tidbit won't help answering, but I think it might clarify what my boss is worried about, we currently start our program at about 18megs, normal working conditions are usually less than 40 megs, he thinks it could climb as high as 120 megs.

• Why do some bad websites rank well?

  - by BradB

  Consider the following scenario: you are pitching SEO/Website Optimisation to a prospective client and you explain to them the importance of great copy and content, how acquiring links (ethically) can increase page rank, why the quality of the HTML build matters (H1, H2 tags, w3c validation etc), why keyword research is beneficial, you may drop in a few Google Webmaster Guideline or Matt Cutts references to back up your claims and rubbish the "back hat" approach as being no longer effective for good measure. Your advice is ethical and in the eyes of best practices, spot on. Then, the client points out to you some of their long established competitors on Google and you see these competitor websites ranking in the top spots (1 to 3) for medium to highly competitive search phrases that your client wants to compete for. These websites totally contradict your ethical approach and pretty much violate every best practice previously noted. They even out perform other "white hat" competitors who are in accordance with the above guidelines. I experienced this today. One of these well ranking websites had: About six microsites with more or less the same copy and a slightly varied layout Little or not textual content I would almost say duplicate content across the sites, but there was so little of it it could barely qualify for being duplicate All the content in Flash (with a music track that kicked in on each page load, not so much of an SEO issue - but it helps paint the picture) Keyword stuffing behind the Flash file with a bunch of black text on black background in the style of keyword 1 keyword 2,keyword1,keyword 2,keyword 2 keyword 3 and so on... The exact keyword stuffed combination present on every page of the website A bunch of clearly self made links from poor quality forums and directories with little or no Page Rank Links exchanged across the microsites How do you explain your way out of this when this hard evidence is sat in front of you undermining your great pitch?

• Friday Fun: Snowball

  - by Asian Angel

  It is Christmas Eve and hopefully you are enjoying the start of an early weekend away from work. This week we have a snowball throwing game for you to try out, so bundle up and get ready to let those snowballs fly! Snowball The object of the game is to use your snowball ammo to harass the drunk businessman and send him flying along distance-wise as far as you can. Simply use your mouse to aim and click the left button to throw snowballs. You can monitor your stats on the silver bar towards the top of the window. The sound can also be disabled if the music is bothering you, but keep in mind that all sound will be disabled if you use the option. Time to get those snowballs flying through the air!! Keep hitting the businessman with your snowballs as you chase after him. Make certain that your aim is good or you will quickly run out of snowballs! You can really get him moving along at a good rate and he can even go high enough in the air to disappear off the screen for a few moments. There is a also chance that your aim will be so wicked with the snowballs that you will literally knock the drunk businessman’s head off! Weird but possible… The game ends when one of these two events occur: 1.) you run out of snowballs or 2.) the businessman literally bounces back at and then drops behind you as seen in the screenshot here. The moment either happens your score will pop up and then you have the opportunity to try again. Have fun! Note: The bounce back event can happen when encountering cars.

• How to Implement Complex Form Data?

  - by SoulBeaver

  I'm supposed to implement a relatively complex form that looks like follows, but has at least four more pages requiring the user to fill in all necessary information for the tracks: This data will need to be sent to the server, which is implemented using Dropwizard. I'm looking for best practices on how to upload and send such a complex form with potentially dozens of songs to the server. The simplest available solution I have seen is a simple multipart/form-data request with the following form schema (Source): Client <html> <body> <h1>File Upload with Jersey</h1> <form action="rest/file/upload" method="post" enctype="multipart/form-data"> <p> Select a file : <input type="file" name="file" size="45" /> </p> <input type="submit" value="Upload It" /> </form> </body> </html> Server @POST @Path("/upload") @Consumes(MediaType.MULTIPART_FORM_DATA) public Response uploadTrack(final FormDataMultiPart multiPart) { List<FormDataBodyPart> artists = multiPart.getFields("artist"); StringBuffer output = new StringBuffer(); for (FormDataBodyPart artist : artists) output.append(artist.getValueAs(String.class)); List<FormDataBodyPart> tracks = multiPart.getFields("track"); for (FormDataBodyPart track : tracks) writeToFile(track.getValueAs(InputStream.class), "Foo"); return Response.status(200).entity(output.toString()).build(); } Then I have also read about file uploads via Ajax or Formdata (Mozilla HttpRequest) which allows for Posts in the formats application/x-www-form-urlencoded, multipart/form-data, or text/plain. I don't know which approach, if any, is best. An ideal solution would be to utilize Jackson to convert a json string into my data objects, but I don't get the impression that this is possible with binary data.

• Is there a "rigorous" method for choosing a database?

  - by Andrew Martin

  I'm not experienced with NoSQL, but one person on my team is calling for its use. I believe our data and its usage isn't optimal for a NoSQL implementation. However, my understanding is based off reading various threads on various websties. I'd like to get some stronger evidence as to who's correct. My question is therefore, "Is there a technique for estimating the performance and requirements of a certain database, that I could use to confirm or modify my intuitions?". Is there, for example, a good book for calculating the performance of equivalent MongoDB/MySQL schema? Is the only really reliable option to build the whole thing and take metrics?

• Hallmarks of a Professional PHP Programmer

  - by Scotty C.

  I'm a 19 year old student who really REALLY enjoys programming, and I'm hoping to glean from your years of experience here. At present, I'm studying PHP every chance I get, and have been for about 3 years, although I've never taken any formal classes. I'd love to some day be a programmer full time, and make a good career of it. My question to you is this: What do you consider to be the hallmarks or traits of a professional programmer? Mainly in the field of PHP, but other, more generalized qualifications are also more than welcome, as I think PHP is more of a hobbyist language and may not be the language of choice in the eyes of potential employers. Please correct me if I'm wrong. Above all, I don't want to wast time on something that isn't worth while. I'm currently feeling pretty confident in my knowledge of PHP as a language, and I know that I could build just about anything I need and have it "work", but I feel sorely lacking in design concepts and code structure. I can even write object oriented code, but in my personal opinion, that isn't worth a hill of beans if it isn't organized well. For this reason, I bought Matt Zandstra's book "PHP Objects, Patterns, and Practice" and have been reading that a little every day. Anyway, I'm starting to digress a little here, so back to the original question. What advice would you give to an aspiring programmer who wants to make an impact in this field? Also, on a side note, I've been working on a project with a friend of mine that would give a fairly good idea of where I'm at coding wise. I'm gonna give a link, I don't want anyone to feel as though I'm pushing or spamming here, so don't click it if you don't want to. But if you are interested on giving some feedback there as well, you can see the code on github. I'm known as The Craw there. https://github.com/PureChat/PureChat--Beta-/tree/

• PHP: A config file in .ini or .php format?

  - by Tim Visee

  I'm working on a huge CMS system, and I asked myself what configuration format I should use. There are two common formats for configuration files. The first one is an INI file, containg all the configuration properties. Then you can simply parse this INI file using build in PHP functions. A second option is to use a PHP file containing a regular PHP array with these configuration properties. Now, it's easier to edit an INI file, but a PHP file give's you more options, for example it allows you to add a function which retrieves one of the configuration options while reading the configuration file. Note: The PHP configuration file would only contain an array of configuration, no initialization functions or anything. (This is possible of course, but it's not implemented by default) Now, what is recommend for me to use as configuration file? What is the most common format for a configuration file? Should I go for simplicity with the INI files, or with a more dynamic one using PHP. One thing to note, this is not for personal usage. I'm planning to release the CMS system soon, and a lot of websites are scheduled already to change to my CMS system.

• Tool to check if XML is valid in my VS2012 comments

  - by davidjr

  I am writing the documentation for our companies software developed with vs2012. I need to add xml examples to the summary of each class, due to xml instantiation of objects. We are using sandcastle to create the documentation (company choice), and I want to be able to review my xml comments without building the help file every time. Is there an application that anyone would recommend where I can view how the xml renders before I build the help file? Here is my example: /// <summary> /// Performs DFT on a data array, writes output in a CSV file. /// </summary> /// <example> /// <para>XML declaration</para> /// <code lang="xml" xml:space="preserve"> /// %lt;DataProvider name="DftDP" description="Computes DFT" etc... I want to check the XML to make sure it is valid, maybe by copy and pasting it into a tool of some sort?

• Why does Komodo edit not open files on doubleclick due to some path encoding error?

  - by gakera

  When I double click a file in finder to open in Komodo edit, it displays an error message saying it can't find the file and the path is displayed, but with wrong encoding, such that special characters such as "ó" and "ð" are displayed as some weird boxes. Screenshot: http://i51.tinypic.com/2qkleg4.jpg I'm running OSX Snow Leopard 10.6.4 and Komodo Edit version 5: "Komodo Edit, version 5.2.4, build 4343, platform macosx-x86. Built on Tue Dec 8 18:18:35 2009." When I drag the file into Komodo edit it opens just fine displaying the path correctly with "ó"s and all :P This doesn't happen if I right click the file in finder and select to open it with TextEdit or Word or (God forbid) MacVim - only when I select to open it in Komodo edit. This is annoying as all hell.

• Good Freelance models for web developers

  - by Matthew Underwood

  I am a web developer with four years of experience in PHP, MYSQL and experience in Javascript etc. One day I hope to develop a freelance career in web development. Areas of freelance that I am thinking of going towards includes Wordpress, Magento development along with bespoke applications. I am also thinking of doing some consultancy work for clients and businesses when I build up some more experience and technical knowledge. I want to offer a web development service to potential clients that plays on my strengths in what I know but most importantly has a market. Web development can cover so many subjects that its difficult to pick out the areas that have demand. I am also curious to find out if web developers offer services that bring in a monthly income e.g application maintenance or database maintenance? Is there a market for certain areas like WordPress plugins or bespoke applications? Are there certain things to avoid because of work duration, unrealistic client expectations or the fact that its impossible to find a market for it? As professional and experienced freelance web developers have you learned some important do's and don'ts? Is there certain services that the majority of web developers offer because its in high demand? This is the one area of web development freelancing that I cant get my head around. I know there is never a definitive answer but there must be some good practises and general consensus on this subject. Web designers design websites they offer a lump sum and get paid monthly sometimes to add new content, PPC and SEO consultants market sites to the top this will involve monthly payments, web development doesn’t seem so clear cut.

• New standalone ESXi 5 deployments - USB versus SD card?

  - by ewwhite

  Now that the old full VMWare ESX with service console is no longer, I'm redeploying some standalone ESXi servers. I'm using HP ProLiant ML and DL G6 and G7 servers. Does it make more sense to utilize the internal USB port for ESXi or the internal SD card slot? I'm using the HP ESXi 5 build, but am not sure what the recommended practice is. Any recommendations on cards/USB drives for this purpose? BTW - these will be all-in-one storage servers with the onboard disk storage presented via PCIe passthrough.
