• Does multiple files in SQL Server when using RAID help reduce conflicts in growth and file-locking?

  - by Dr Giles M

  I've been reading around and get the impression that if you are using RAID then using multiple SQL Server files within a filegroup won't yeild any more improvements, and the benefits are purely administrative (if you started to run out of space or wanted to partition off data into managable chunks for backups/balancing the data around your big server room). However, being a reasonably savvy software person, it's not unthinkable to hypothesise that, even for smaller databases that SQL Server will perform growth and locking operations (for writes) on a LOGICAL file basis, so even if you are using RAID, it seems to make sense to have multiple files in a file group to balance I/O, or does the time taken to reconstruct the data from distributed filegroups outweigh the benefits of reduced locking? I'm also aware that the behaviour and benefits may be different for tables/indeces/log. Is there a good site that distinguishes the benefits of multiple files when RAID is already in place?

• SQL Azure Service Issues &ndash; 10.27.2012 (Restored Now)

  - by ToStringTheory

  Please note that if you have a Windows Azure website, or use SQL Azure, your site may be experiencing downtime currently.  Notice I just called in regarding one of my public facing internet sites, because the site was failing to load anything but its error page, I couldn’t connect to the database to inspect application error logs, and the Windows Azure Management portal won’t load the SQL Azure extension. After speaking to the representative, he also mentioned that they were also having some problems updating the Service Dashboard which shows service up/down time, and for now, they are posting messages at http://account.windowsazure.com.  Please note that this issue may only be effecting certain regions.  Last, I may have misheard the representative, but he said that the outage was being categorized as a level 8, and if I heard correctly, I think he said that level 8 was the worst level.  I can’t say for sure on this though, because the phone connection to their support number was bad – large amounts of white noise. Good Luck! Update It appears that this outage may also be effecting the following services: SQL Database, Service Bus, Datamarket, Windows Azure Marketplace, Shared Caching, Access Control 2.0, and SQL Reporting. The note on the account page says for the South Central US region, however, I believe the representative I spoke to also mentioned North Central. As I said before though, the connection was bad. Update 2 My site regained connectivity about an hour ago, and it appears that the service dashboard is back in operation with correct status and history. It does appear that I misheard on the phone regarding multiple regions, so chances are this only effected a percentage of the platform. All in all, if this WAS their worst level of a problem, they really got it fixed and back up pretty fast. All in all, I understand that it is inherent for a complex system such as Azure to have ups and downs, but at the end of the day, I am still happy to support Azure to its fullest!

• displaying multi-section html documents - best practices

  - by ecpepper

  I work at a research organization and we publish a lot of large-ish documents, usually organized in sections. What I want to know is how best to present these multi-section documents on our website. Presently, what I do is load the entire document as a single page, with each section as its own div. Then I show and hide divs as needed via a table of contents and "next" and "prev" buttons. The advantages to this are mainly: 1) that you can move between sections very quickly, 2) it produces consistent analytics (when a page is loaded, I know a report is being read). The disadvantages, however, are real: Readers can't take advantage of browser back/forward buttons to move between sections. It's complicated to create direct links to individual sections (I can do it with javascript but it's not easy for other people to grab and share). For long reports, you have to wait for the full report to load before you can move around (and that can include hordes of images and charts). Do other people have thoughts on better ways to organize this? Here's an example of the current system: http://massbudget.org/825

• XP Computer won't start (Missing/Corrupt 'System' file) - recently added new hard drive

  - by qwerty2

  Hi all, Pulling my hair out here. I recently replaced my D: 1TB drive (not a system drive) with a new 1.5TB drive. I loaded Windows XP, formatted the new drive and it was showing as working fine, alongside my C: windows system drive. I restart my machine and all of a sudden, Windows doesn't load and instead I get: "Windows could not start beause the following file is missing or corrupt" \WINDOWS\SYSTEM32\CONFIG\SYSTEM I don't have the original XP installation CD, although I do have another copy of XP, when I try and boot to it, I get the blue 'STOP' screen after it attempts to load the setup utlity for about a minute. Can someone please help? When I set up my new hard drive as a primary partition did this someone screw up my C: hard drive? Did it perhaps unmount it somehow? Any help would be fantastic. Thanks

• Converting from mp4 to Xvid avi using avconv?

  - by Ricardo Gladwell

  I normally use avidemux to convert mp4s to Xvid AVI for my Philips Streamium SLM5500. Normally I select MPEG-4 ASP (Xvid) at Two Pass with an average bitrate f 1500kb/s for video and AC3 (lav) audio and it converts correctly. However, I'm trying to using avconv so I can automate the process with a script, but when I do this the video stutters and stops playing part way through. I have a suspicion its something to do with a faulty audio conversion. The commands I'm using are as follows: avconv -y -i video.mp4 -pass 1 -vtag xvid -c:a ac3 -b:a 128k -b:v 1500k -f avi /dev/null avconv -y -i video.mp4 -pass 2 -vtag xvid -c:a ac3 -b:a 128k -b:v 1500k -f avi video.avi There is a bewildering array of arguments for avconv. Is there something I'm doing wrong? Is there a way I can script avidemux from a headless server? Please see command line output: $ avconv -y -i video.mp4 -pass 1 -vtag xvid -an -b:v 1500k -f avi /dev/null avconv version 0.8.5-6:0.8.5-0ubuntu0.12.10.1, Copyright (c) 2000-2012 the Libav developers built on Jan 24 2013 14:49:20 with gcc 4.7.2 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'video.mp4': Metadata: major_brand : isom minor_version : 1 compatible_brands: isomavc1 creation_time : 2013-02-04 13:53:38 Duration: 00:44:09.16, start: 0.000000, bitrate: 669 kb/s Stream #0.0(und): Video: h264 (High), yuv420p, 720x404 [PAR 1:1 DAR 180:101], 538 kb/s, 25 fps, 25 tbr, 100 tbn, 50 tbc Metadata: creation_time : 2013-02-04 13:53:38 Stream #0.1(und): Audio: ac3, 44100 Hz, stereo, s16, 127 kb/s Metadata: creation_time : 2013-02-04 13:53:42 [buffer @ 0x7f4c40] w:720 h:404 pixfmt:yuv420p Output #0, avi, to '/dev/null': Metadata: major_brand : isom minor_version : 1 compatible_brands: isomavc1 creation_time : 2013-02-04 13:53:38 ISFT : Lavf53.21.1 Stream #0.0(und): Video: mpeg4, yuv420p, 720x404 [PAR 1:1 DAR 180:101], q=2-31, pass 1, 1500 kb/s, 25 tbn, 25 tbc Metadata: creation_time : 2013-02-04 13:53:38 Stream mapping: Stream #0:0 -> #0:0 (h264 -> mpeg4) Press ctrl-c to stop encoding frame=66227 fps=328 q=2.0 Lsize= 0kB time=2649.16 bitrate= 0.0kbits/s video:401602kB audio:0kB global headers:0kB muxing overhead -100.000000% $ avconv -y -i video.mp4 -pass 2 -vtag xvid -c:a ac3 -b:a 128k -b:v 1500k -f avi video.avi avconv version 0.8.5-6:0.8.5-0ubuntu0.12.10.1, Copyright (c) 2000-2012 the Libav developers built on Jan 24 2013 14:49:20 with gcc 4.7.2 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'video.mp4': Metadata: major_brand : isom minor_version : 1 compatible_brands: isomavc1 creation_time : 2013-02-04 13:53:38 Duration: 00:44:09.16, start: 0.000000, bitrate: 669 kb/s Stream #0.0(und): Video: h264 (High), yuv420p, 720x404 [PAR 1:1 DAR 180:101], 538 kb/s, 25 fps, 25 tbr, 100 tbn, 50 tbc Metadata: creation_time : 2013-02-04 13:53:38 Stream #0.1(und): Audio: ac3, 44100 Hz, stereo, s16, 127 kb/s Metadata: creation_time : 2013-02-04 13:53:42 [buffer @ 0x12b4f00] w:720 h:404 pixfmt:yuv420p Incompatible sample format 's16' for codec 'ac3', auto-selecting format 'flt' [mpeg4 @ 0x12b3ec0] [lavc rc] Using all of requested bitrate is not necessary for this video with these parameters.

• Announcing Oracle Knowledge 8.5: Even Superheroes Need Upgrades

  - by Richard Lefebvre

  It’s no secret that we like Iron Man here at Oracle. We've certainly got stuff in common: one of the world’s largest technology companies and one of the world’s strongest technology-driven superheroes. If you've seen the recent Iron Man movies, you might have even noticed some of our servers sitting in Tony Stark’s lab. Heck, our CEO made a cameo appearance in one of the movies. Yeah, we’re fans. Especially as Iron Man is a regular guy with some amazing technology – like us. But Like all great things even Superheroes need upgrades, whether it’s their suit, their car or their spacestation. Oracle certainly has its share of advanced technology.  For example, Oracle acquired InQuira in 2011 after years of watching the company advance the science of Knowledge Management.  And it was some extremely super technology.  At that time, Forrester’s Kate Leggett wrote about it in ‘Standalone Knowledge Management Is Dead With Oracle's Announcement To Acquire InQuira’ saying ‘Knowledge, accessible via web self-service or agent UIs, is a critical customer service component for industries fielding repetitive questions about policies, procedures, products, and solutions.’  One short sentence that amounts to a very tall order.  Since the acquisition our KM scientists have been hard at work in their labs. Today Oracle announced its first major knowledge management release since its acquisition of InQuira: Oracle Knowledge 8.5. We’ve put a massively-upgraded supersuit on our KM solution because we still have bad guys to fight. And we are very proud to say that we went way beyond our original plans. So what, exactly, did we do in Oracle Knowledge 8.5? We did what any high-tech super-scientist would do. We made Oracle Knowledge smarter, stronger and faster. First, we gave Oracle Knowledge a stronger heart: Certified on Oracle technologies, including Oracle WebLogic Server, Oracle Business Intelligence, Oracle Exadata Database Machine and Oracle Exalogic Elastic Cloud. Huge scaling and performance improvements. Then we gave it a better reach: Improved iConnect functionality that delivers contextualized knowledge directly into CRM applications. Better content acquisition support across disparate sources. Enhanced Language Support including Natural Language search support for 16 Languages. Enhanced Keyword Search for 23 authoring languages, as well as enhanced out-of-the-box industry ontologies covering 14 languages. And finally we made Oracle Knowledge ridiculously smarter: Improved Natural Language Search and a new Contextual Answer Delivery that understands the true intent of each inquiry to deliver the best possible answers. AnswerFlow for Guided Navigation & Answer Delivery, a new application for guided troubleshooting and answer delivery. Knowledge Analytics standardized on Oracle’s Business Intelligence Enterprise Edition. Knowledge Analytics Dashboards optimized search and content creation through targeted, actionable insights. A new three-level language model "Global - Language - Locale" that provides an improved search experience for organizations with a global footprint. We believe that Oracle Knowledge 8.5 is the most sophisticated KM solution in existence today and we’ve worked very hard to help it fulfill the promise of KM: empowering customers and employees with deep insights wherever they need them. We hope you agree it’s a suit worth wearing. We are continuing to invest in Knowledge Management as it continues to be especially relevant today with the enterprise push for peer collaboration, crowd-sourced wisdom, agile innovation, social interaction channels, applied real-time analytics, and personalization. In fact, we believe that Knowledge Management is a critical part of the Customer Experience portfolio for success. From empowering employee’s, to empowering customers, to gaining the insights from interactions across all channels, businesses today cannot efficiently scale their efforts, strengthen their customer relationships or achieve their growth goals without a solid Knowledge Management foundation to build from. And like every good superhero saga, we’re not even close to being finished. Next we are taking Oracle Knowledge into the Cloud. Yes, we’re thinking what you’re thinking: ROCKET BOOTS! Stay tuned for the next adventure… By Nav Chakravarti, Vice-President, Product Management, CRM Knowledge and previously the CTO of InQuira, a knowledge management company acquired by Oracle in 2011

• Using XML in a Flex Website to Improve SEO

  - by Laxmidi

  Hi, I've got a Flex 3 site called www.brainpinata.com that's a trivia game. Basically, everything in the site is pulled from a database-- the questions, choices, and answers. So, unfortunately, Google doesn't index my content. So, I'm trying to think of ways to improve the situation: A) If I took my database data and put it in an XML file which was in the website's root directory, would this work? Would it violate any Google policy? (The info would be the same as in the db-- so nothing shady.) Would I have to "wire" the XML into my site or would it be enough to just have the XML sitting in the root directory? B) Another idea is to use the noscript tag and load the XML content there. As I understand it Google indexes content that people who have Javascript turned off would see. I know Flex/Actionscript 3, and unfortunately, I don't know how to load XML content with HTML. Does anyone know of an example where a Flex site uses XML for the noscript content? Thank you. -Laxmidi

• wubi dual-boot installation of ubuntu 12.04 on Windows 7 fails to boot

  - by Andrew

  I am trying to use the wubi installation process to create a Ubuntu 12.04 / Windows 7 dual boot setup on my Windows 7 machine (Dell Inspiron 17R). The installation initially works fine, and I am able to load Ubuntu several times after selecting it from the boot menu. However, when I boot into Windows 7 it seems to corrupt the Ubuntu boot process, because after running Windows 7, Ubuntu won't boot on the machine. It is still listed as an option in the boot menu, but when it is selected, the machine does one of the following: -hangs at the load-screen and says that Ubuntu is preparing to run for the first time (although it isn't the first time the OS has been loaded) -hangs with a black screen and does nothing I have uninstalled Ubuntu and then reinstalled it (using wubi) three times. Each time Ubuntu initially boots okay (including rebooting the laptop into Ubuntu several times.) However, whenever I switch over and boot into Windows 7 it breaks the Ubuntu installation. Windows 7 continues to boot and work fine without issues. I have successfully installed Ubuntu using wubi onto a different Windows 7 machine before without problems...it seems that there is something different about this laptop configuration. I am not sure how to debug the issue. I see no error messages during the Ubuntu boot process when it hangs and am not sure how to debug this.

• How to migrate part of an SVN repository?

  - by dehmann

  How do you migrate a part of an SVN repository into a new repository? To migrate the contents of a complete SVN repository into a new repository, one has to dump the old repository first: svnadmin dump /path/to/repository > repository-name.dmp and then load it into the new one using svnadmin load. But I'm not sure how to just migrate a part. Do I still have to dump the whole thing? Do I grep for the part that I want? To just dump myproject, I tried this, but it didn't work: svnadmin dump /path/to/repository/myproject Any ideas?

• XNA 4.0: Problem with loading XML content files

  - by 200

  I'm new to XNA so hopefully my question isn't too silly. I'm trying to load content data from XML. My XML file is placed in my Content project (the new XNA 4 thing), called "Event1.xml": <?xml version="1.0" encoding="utf-8" ?> <XnaContent> <Asset Type="MyNamespace.Event"> // error on this line <name>1</name> </Asset> </XnaContent> My "Event" class is placed in my main project: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Xml.Linq; namespace MyNamespace { public class Event { public string name; } } The XML file is being called by my main game class inside the LoadContent() method: Event temp = Content.Load<Event>("Event1"); And this is the error I'm getting: There was an error while deserializing intermediate XML. Cannot find type "MyNamespace.Event" I think the problem is because at the time the XML is being evaluated, the Event class has not been established because one file is in my main project while the other is in my Content project (being a XNA 4.0 project and such). I have also tried changing the build action of the xml file from compile to content; however the program would then not be able to find the file and would give this other warning: Project item 'Event1.xml' was not built with the XNA Framework Content Pipeline. Set its Build Action property to Compile to build it. Any suggestions are appreciated. Thanks.

• Windows Photo Viewer needs more ram?

  - by Aren B

  Ok, so i went to open a picture with the Windows Photo Viewer (Default) application and it told me this: Windows Photo Viewer can't display this picture because there might not be enough memory available on your computer. Close some programs that you aren't using or free some hard disk space (if it's almost full), and then try again. So looking at my 98% ram usage (thankyou VisualStudio x8 + SQL Server) I rebooted my computer. Now this is my load: And this is my hard-disk loadout: So now I go to load up that image again. SAME MESSAGE, what the heck? So apparantly 6gb isn't enough ram to open a 29k image that loads perfectly fine in MSPaint, Paint.NET, Photoshop It's a .png and it's not corrupt. So my question is: what gives?

• How to host customer developed code server side

  - by user963263

  I'm developing a multi-tenant web application, most likely using ASP.NET MVC5 and Web API. I have used business applications in the past where it was possible to upload custom DLL's or paste in custom code to a GUI to have custom functions run server side. These applications were self hosted and single-tenant though so the customer developed bits didn't impact other clients. I want to host the multi-tenant web application myself and allow customers to upload custom code that will run server side. This could be for things like custom web services that client side JavaScript could interact with, or it could be for automation steps that they want triggered server side asynchronously when a user takes a particular action. Additionally, I want to expose an API that allows customers' code to interact with data specific to the web application itself. Client code may need to be "wrapped" so that it has access to appropriate references - to our custom API and maybe to a white list of approved libraries. There are several issues to consider - security, performance (infinite loops, otherwise poorly written code, load balancing, etc.), receive compiled DLL's or require raw code, etc. Is there an established pattern for this sort of thing or a sample project anyone can point to? Or any general recommendations?

• The Hot-Add Memory Hogs

  - by Andrew Clarke

  One of the more difficult tasks, when virtualizing a server, is to determine the amount of memory that Hypervisor should assign to the virtual machine. This requires accurate monitoring and, because of the consequences of setting the value too low, there is a great temptation to err on the side of over-provisioning. This results in fewer guest VMs and, in fact, with more accurate memory provisioning, many virtual environments could support 30% more VMs. In order to achieve a better consolidation (aka VM density) ratio, Windows Server 2008 R2 SP1 has introduced what Microsoft calls ‘Dynamic Memory’. This means that the start-up RAM VM memory assigned to guest virtual machines can be allowed to vary according to demand, changing dynamically while the VM is running, based on the workload of applications running inside. If demand outstrips supply, then memory can be rationed according to the ‘memory weight’ assigned to the guest VM. By this mechanism, memory becomes a shared resource that can be reallocated automatically as demand patterns vary. Unlike VMWare’s Memory Overcommit technology, the sum of all the memory allocations to each virtual machine will not exceed the total memory of the host computer. This is fine for applications that are self-regulating in their demands for memory, releasing memory back into the 'pool' when not under peak load. Other applications however, such as SQL Server Standard and Enterprise, are by nature, memory hogs under high workload; they can grab hot-add memory whilst running under load and then never release it. This requires more careful setting-up and the SQLOS team have provided some guidelines from for configuring SQL Server in virtual environments. Whereas VMWare’s Memory Overcommit is well-proven in a number of different configurations, Hyper-V’s ‘Dynamic Memory’ is new. So far, the indications are that it will improve the business case for virtualizing and it is probably a far more intuitive technology for the average IT professional to grasp. It is certainly worth testing to see whether it works for you.

• Ubuntu 9.0.4 Presario S4000NX Fan Speed

  - by Chris C

  I recently install Ubuntu 9.0.4 on a Presario S4000NX and the CPU fan speed is kept at max. With Windows XP installed the fan speed would increase/decrease as required. I've tried to install lm-sensors and run the sensors-detect. It recommended that I load the modules which I did: smsc47m192 i2c-i801 When running sensor-detect it gave me this strange message: Trying family SMSC Found SMSC LPC47M15x/192/997 Super IO Fan Sensors (but not activated) Running the sensors command gives me a list of voltages and CPU and temperature but doesn't list any fans. After doing some Internet research I then tried to load the smsc47m1 module but I get the following error: FATAL: Error inserting smsc47m1 (/lib/modules/2.6.28-15-generic/kernel/drivers/hwmon/smsc47m1.ko): no such device The file smsc47m1.ko does exist in the listed folder. Any suggestions for getting the fan speed (and the noise) down in Ubuntu? Thanx. - Chris P.S. - I would have put better tags but Server Fault wouldn't let me.

• Announcing Oracle Knowledge 8.5: Even Superheroes Need Upgrades

  - by Chris Warner

  It’s no secret that we like Iron Man here at Oracle. We've certainly got stuff in common: one of the world’s largest technology companies and one of the world’s strongest technology-driven superheroes. If you've seen the recent Iron Man movies, you might have even noticed some of our servers sitting in Tony Stark’s lab. Heck, our CEO made a cameo appearance in one of the movies. Yeah, we’re fans. Especially as Iron Man is a regular guy with some amazing technology – like us. But Like all great things even Superheroes need upgrades, whether it’s their suit, their car or their spacestation. Oracle certainly has its share of advanced technology.  For example, Oracle acquired InQuira in 2011 after years of watching the company advance the science of Knowledge Management.  And it was some extremely super technology.  At that time, Forrester’s Kate Leggett wrote about it in ‘Standalone Knowledge Management Is Dead With Oracle's Announcement To Acquire InQuira’ saying ‘Knowledge, accessible via web self-service or agent UIs, is a critical customer service component for industries fielding repetitive questions about policies, procedures, products, and solutions.’  One short sentence that amounts to a very tall order.  Since the acquisition our KM scientists have been hard at work in their labs. Today Oracle announced its first major knowledge management release since its acquisition of InQuira: Oracle Knowledge 8.5. We’ve put a massively-upgraded supersuit on our KM solution because we still have bad guys to fight. And we are very proud to say that we went way beyond our original plans. So what, exactly, did we do in Oracle Knowledge 8.5? We did what any high-tech super-scientist would do. We made Oracle Knowledge smarter, stronger and faster. First, we gave Oracle Knowledge a stronger heart: Certified on Oracle technologies, including Oracle WebLogic Server, Oracle Business Intelligence, Oracle Exadata Database Machine and Oracle Exalogic Elastic Cloud. Huge scaling and performance improvements. Then we gave it a better reach: Improved iConnect functionality that delivers contextualized knowledge directly into CRM applications. Better content acquisition support across disparate sources. Enhanced Language Support including Natural Language search support for 16 Languages. Enhanced Keyword Search for 23 authoring languages, as well as enhanced out-of-the-box industry ontologies covering 14 languages. And finally we made Oracle Knowledge ridiculously smarter: Improved Natural Language Search and a new Contextual Answer Delivery that understands the true intent of each inquiry to deliver the best possible answers. AnswerFlow for Guided Navigation & Answer Delivery, a new application for guided troubleshooting and answer delivery. Knowledge Analytics standardized on Oracle’s Business Intelligence Enterprise Edition. Knowledge Analytics Dashboards optimized search and content creation through targeted, actionable insights. A new three-level language model "Global - Language - Locale" that provides an improved search experience for organizations with a global footprint. We believe that Oracle Knowledge 8.5 is the most sophisticated KM solution in existence today and we’ve worked very hard to help it fulfill the promise of KM: empowering customers and employees with deep insights wherever they need them. We hope you agree it’s a suit worth wearing. We are continuing to invest in Knowledge Management as it continues to be especially relevant today with the enterprise push for peer collaboration, crowd-sourced wisdom, agile innovation, social interaction channels, applied real-time analytics, and personalization. In fact, we believe that Knowledge Management is a critical part of the Customer Experience portfolio for success. From empowering employee’s, to empowering customers, to gaining the insights from interactions across all channels, businesses today cannot efficiently scale their efforts, strengthen their customer relationships or achieve their growth goals without a solid Knowledge Management foundation to build from. And like every good superhero saga, we’re not even close to being finished. Next we are taking Oracle Knowledge into the Cloud. Yes, we’re thinking what you’re thinking: ROCKET BOOTS! Stay tuned for the next adventure… By Nav Chakravarti, Vice-President, Product Management, CRM Knowledge and previously the CTO of InQuira, a knowledge management company acquired by Oracle in 2011.

• Can AJAX in a CMS slow down your server

  - by Saif Bechan

  I am currently developing some plugins for WordPress, and I was wondering which route to take. Let's take an example, you want to display the last 3 tweets on your page. Option 1 You do things the normal way inside WordPress. Someone enters the website, while generating the page, you fetch the tweets in php via the twitter api, and just display them where you want. Now the small problem with this is, that you have to wait for the response from twitter. This takes a few ms. NO real problem, but this is question is just out of curiosity. Option 2 Here you don't do anything in WordPress on the initial load, but you do have the API inside. Now you just generate the page, and as soon as the page is done on the client side, you do a small AJAX call back to the server via a WordPress plugin, to fetch your latest tweets. Also called asynchronously. Now the problem with this IMO is that you have much more stress on your server. For starters you have two HTTP requests instead of one. Secondly the WordPress core has to load two times instead of one. Other options Now I know there are a lot of other options: 1) Getting the tweets directly via javascript, no stress on the server at all. 2) Cache the tweets so they are fetched from the DB instead of using the API every time. 3) Getting the tweets from an ajax call that is not a WordPress plugin. 4) Many more. My Question Now my question is if you only compare 1 and 2, which would be a better choice.

• Inspiring a co-worker to adopt better coding practices?

  - by Aaronaught

  In the Handling my antiquated coworker question, various people discussed strategies for dealing with coworkers who are unwilling to integrate their workflow with the team's. I'd like, if possible, to learn some strategies for "teaching" a coworker who is merely ignorant of modern techniques and tools, and possibly a little apathetic. I've started working with a programmer who until recently has been working in relative isolation, in a different part of the company. He has extensive domain knowledge and most importantly he has demonstrated good problem-solving skills, something which many candidates seem to lack. However, the actual (C#) code I've seen is a throwback to the VB6 days. Procedural structure, Hungarian notation, global variables (abuse of static), no interfaces, no tests, non-use of Generics, throwing System.Exception... you get the idea. This programmer is a fair bit older than I am and, by first impressions at least, doesn't actively seek positive change. I'm not going to say resistant to change, because I think that is largely an issue of how the topic gets broached, and I want to be prepared. Programmers tend to be stubborn people, and going in with guns blazing and instituting rip-it-to-shreds code reviews and strictly-enforced policies is very likely not going to produce the end result that I want. If this were a new hire, a junior programmer, I wouldn't think twice about taking a "mentor" stance, but I'm extremely wary of treating an experienced employee as a clueless newbie (which he's not - he just hasn't kept pace with certain advancements in the field). How might I go about raising this developer's code quality standard the Dale Carnegie way, through gentle persuasion and non-material incentives? What would be the best strategy for effecting subtle, gradual changes, without creating an adversarial situation? Have other people - especially lead developers - been in this type of situation before? Which strategies were successful at stimulating interest and creating a positive group dynamic? Which strategies weren't successful and would be better to avoid? Clarifications: I really feel that several people are answering based on personal feelings without actually reading all of the details of the question. Please note the following, which should have been implied but I am now making explicit: This coworker is only my "senior" by virtue of age. I never said that his title, sphere of influence, or years at the organization exceed mine, and in fact, none of those things are true. He's a LOB programmer who's been absorbed into the main development shop. That's it. I am not a new hire, junior programmer, or other naïve idiot with grand plans to transform the company overnight. I am basically in charge of the software process, but as many who've worked as "leads" will know, responsibilities don't always correlate precisely with the org chart. I'm not asking people how to get my way, come hell or high water. I could do that if I wanted to, with the net result being that this person would become resentful and/or quit. Please try to understand that I am looking for a social, cooperative method of driving change. The mention of "...global variables... no tests... throwing System.Exception" was intended to demonstrate that the problems are not just superficial or aesthetic. Practices that may work for relatively small CRUD apps do not necessarily work for large enterprise apps, and in fact, none of the code so far has actually passed the integration tests. Please, try to take the question at face value, accept that I actually know what I'm talking about, and either answer the question that I actually asked or move on. P.S. My sincerest gratitude to those who -did- offer constructive advice rather than arguing with the premise. I'm going to leave this open for a while longer as I'm hoping to hear more in the way of real-world experiences.

• Websockets through Stunnel is giving random bytes.

  - by user16682

  I have several servers set up for a web application that I am developing. One is a load balancing server, and I'm running a php WebSockets server on this balancer. The website that I am developing on uses ssl, so I have my WebSockets running through a wss uri connecting directly to the balancer, where I have set up stunnel4 to decrypt all traffic at a certain port and re-rout it to my php WebSockets server. This works fine when it comes down to connecting to my server. That's not the problem. The problem occurs when I try to send data to the server. Occasionally when I try this, stunnel does not appear to be decrypting the data properly. I get garbage characters in my termanal running the server: what appear to be completely random bytes. This can sometimes go on for several consecutive messages that I send before abruptly working again. It is very erratic and unpredictable. Sometimes I refresh the page, and all the messages work perfectly. Sometimes the WebSocket connects and I have to wait 5-10 seconds before any messages I send are interpreted properly by the server. Other times I can't send any messages at all, because they all end up as garbage. I believe this is a stunnel problem, but I am not certain. Does anybody have any experience with this? I would like a more predictable server if I can get it. Some more information: This occurs extensively in Chrome, not quite as much in FireFox, and never in Safari. The php server I am using is phpws http://code.google.com/p/phpws/ -- On the WebSocket connection, this server would sometimes detect that the header was only 1 byte in size, the first byte of the WebSockets header. I had to modify the server to flush the buffer ever time this occurred so that it would reliably connect.
