• JDK bug migration: bugs.sun.com now backed by JIRA

  - by darcy

  The JDK bug migration from a Sun legacy system to JIRA has reached another planned milestone: the data displayed on bugs.sun.com is now backed by JIRA rather than by the legacy system. Besides maintaining the URLs to old bugs, bugs filed since the migration to JIRA are now visible too. The basic information presented about a bug is the same as before, but reformatted and using JIRA terminology: Instead of a "category", a bug now has a "component / subcomponent" classification. As outlined previously, part of the migration effort was reclassifying bugs according to a new classification scheme; I'll write more about the new scheme in a subsequent blog post. Instead of a list of JDK versions a bug is "reported against," there is a list of "affected versions." The names of the JDK versions have largely been regularized; code names like "tiger" and "mantis" have been replaced by the release numbers like "5.0" and "1.4.2". Instead of "release fixed," there are now "Fixed Versions." The legacy system had many fields that could hold a sequence of text entries, including "Description," "Workaround", and "Evaluation." JIRA instead only has two analogous fields labeled as "Description" and a unified stream of "Comments." Nearly coincident with switching to JIRA, we also enabled an agent which automatically updates a JIRA issue in response to pushes into JDK-related Hg repositories. These comments include the changeset URL, the user making the push, and a time stamp. These comments are first added when a fix is pushed to a team integration repository and then added again when the fix is pushed into the master repository for a release. We're still in early days of production usage of JIRA for JDK bug tracking, but the transition to production went smoothly and over 1,000 new issues have already been filed. Many other facets of the migration are still in the works, including hosting new incidents filed at bugs.sun.com in a tailored incidents project in JIRA.

• cpufreq not available 11.10

  - by code shogan

  on 11.04 I had cpufreq working on my "AMD Turion(tm) 64 X2 Mobile Technology TL-50 stepping 02" processors, however now on oneiric cpufreq won't load. The core temperature of my cpu is normally 40 c, but lately it's cooking away at 75-80+ c and the fan is always extremely loud even when cpu usage has at 0.4%. and after this dmesg | grep -i cpu I got: Brought up 2 CPUs Switch to broadcast mode on CPU1 Switch to broadcast mode on CPU0 Switched to NOHz mode on CPU #1 Switched to NOHz mode on CPU #0 ACPI: acpi_idle registered with cpuidle cpufreq-nforce2: No nForce2 chipset. cpuidle: using governor ladder cpuidle: using governor menu powernow-k8: Found 1 AMD Turion(tm) 64 X2 Mobile Technology TL-50 (2 cpu cores) (version 2.20.00) I see something about governors and ladder there, does this mean the OS is able to scale my cpu's or not? If so is there a way I can determine it's working? I saw that for other users that the wrong module had been loaded and by disabling it they were able to get cpufreq loaded.

• How to Enable User-Specific Wireless Networks in Windows 7

  - by The Geek

  Wireless network settings in Windows 7 are global across all users, but there’s a little-known option that lets you switch them to per-user, so each user has access to only the networks they are allowed to connect to. Here’s how it all works. How is this useful? Maybe you want to prevent a particular user from accessing the internet—if you don’t give them the wireless password, they won’t be able to get online.

• Which language is more suitable heavy file tasks?

  - by All

  I need to write a script (based on basic functions) to process /image/audio/video files. The process is mainly filesystem tasks and converts. The database of files has been stored by mysql. The script is simple but cause heavy tasks on the system; for example renaming/converting/copying thousands of file in a run. The script does not read the content of files into memory, it just manage the commands for sub-processes. The main weight is on the communication with filesystem. The script will be used regularly for new files. My concern is about performance. I am thinking of Shell script a complied language like C Please advise which programming language is more suitable for this purpose and why? UPDATE: An example is to scan a folder for images, convert them with ImageMagick, move files to destination folder, get file info, then update the database. As you can see, the process has no room for optimization, and most of languages have similar APIs for popular programs like ImageMagick, MySQL, etc. Thus, it can be written in any language. I just wish to reduce resource usage by speeding up the long loop. NOTE: I know that questions about comparing languages are not favorable, but I really had problem to choose, because the problems can appear in action.

• Logging library for (c++) games

  - by Klaim

  I know a lot of logging libraries but didn't test a lot of them. (GoogleLog, Pantheios, the coming boost::log library...) In games, especially in remote multiplayer and multithreaded games, logging is vital to debugging, even if you remove all logs in the end. Let's say I'm making a PC game (not console) that needs logs (multiplayer and multithreaded and/or multiprocess) and I have good reasons for looking for a library for logging (like, I don't have time or I'm not confident in my ability to write one correctly for my case). Assuming that I need : performance ease of use (allow streaming or formating or something like that) reliable (don't leak or crash!) cross-platform (at least Windows, MacOSX, Linux/Ubuntu) Wich logging library would you recommand? Currently, I think that boost::log is the most flexible one (you can even log to remotely!), but have not good performance. Pantheios is often cited but I don't have comparison points on performance and usage. I've used my own lib for a long time but I know it don't manage multithreading so it's a big problem, even if it's fast enough. Google Log seems interesting, I just need to test it but if you already have compared those libs and more, your advice might be of good use. Games are often performance demanding while complex to debug so it would be good to know logging libraries that, in our specific case, have clear advantages.

• Hack a Linksys Router into a Ambient Data Monitor

  - by Jason Fitzpatrick

  If you have a data source (like a weather report, bus schedule, or other changing data set) you can pull it and display it with an ambient data monitor; this fun build combines a hacked Linksys router and a modified toy bus to display transit arrival times. John Graham-Cumming wanted to keep an eye on the current bus arrival time tables without constantly visiting the web site to check them. His workaround turns a hacked Linksys router, a display, a modified London city bus (you could hack apart a more project-specific enclosure, of course), and a simple bit code that polls the bus schedule’s API, into a cool ambient data monitor that displays the arrival time, in minutes, of the next two buses that will pass by his stop. The whole thing could easily be adapted to another API to display anything from stock prices to weather temps. Hit up the link below for more information on the project.

• Visual Studio 2010 editor painfully slow

  - by Daniel Gehriger

  I'm running out of patience with MS VisualStudio 2010: I'm working on a solution containing ~50 C++ projects. When using the editor, I experience a lag of 1 - 2 seconds whenever I move the cursor to a different line, or when I move to a different window, or generally when the editor losses and gains focus. I went through a whole series of optimizations, to no avail: installed all hotfixes for VS2010 disabled all add-ins and extensions disabled Intellisense deleted all temporary files created by VS2010 disabled hardware acceleration unloaded all but 15 projects disabled tracking changes closed all but one window and so on. This is on a Dual Core machine with SSD harddrive (verified throughput 100MB/s), enough free space on HD, Windows 7 Pro 32-bit with 3GB of RAM and most of it still free. Whenever I type a letter, CPU usage of devenv.exe goes to 50 - 90% in process monitor for 1 - 2 seconds before returning to 5%. I used Process Explorer to analyze registry and file system access, and I only notice frequent accesses to the .sln file (which is quiet small), and a few registry reads, but nothing that would raise a red flag. I don't have this problem with solutions containing less projects, so I'm inclined to think that it's related to the number of projects. For your information, the entire solution has been migrated over the years from VS2005 to VS2008 to now VS2010. Does anyone have any ideas what else I could do to resume work on this project, other than returning to VS2008?

• SOA Starting Point: Methods for Service Identification and Definition

  As more and more companies start to incorporate a Service Oriented Architectural design approach into their existing enterprise systems, it creates the need for a standardized integration technology. One common technology used by companies is an Enterprise Service Bus (ESB). An ESB, as defined by Progress Software, connects and mediates all communications and interactions between services. In essence an ESB is a form of middleware that allows services to communicate with one another regardless of framework, environment, or location. With the emergence of ESB, a new emphasis is now being placed on approaches that can be used to determine what Web services should be built. In addition, what order should these services be built? In May 2011, SOA Magazine published an article that identified 10 common methods for identifying and defining services. SOA’s Ten Common Methods for Service Identification and Definition: Business Process Decomposition Business Functions Business Entity Objects Ownership and Responsibility Goal-Driven Component-Based Existing Supply (Bottom-Up) Front-Office Application Usage Analysis Infrastructure Non-Functional Requirements  Each of these methods provides various pros and cons in regards to their use within the design process. I personally feel that during a design process, multiple methodologies should be used in order to accurately define a design for a system or enterprise system. Personally, I like to create a custom cocktail derived from combining these methodologies in order to ensure that my design fits with the project’s and business’s needs while still following development standards and guidelines. Of these ten methods, I am particularly fond of Business Process Decomposition, Business Functions, Goal-Driven, Component-Based, and routinely use them in my designs.  Works Cited Hubbers, J.-W., Ligthart, A., & Terlouw , L.

• Custom inventory items based on inheritance

  - by Bogdan Marginean

  So, here's the scenario: I'm building an RPG. Like most of the other RPGs on the market, my game will feature an inventory and of course, inventory items. So far I've worked well with using a single class for all items, because I did not need anything else than character stat alteration on item usage (consumption). However, I'd like some items to have a more exotic effect. Think of something like when the user consumes a transformation potion, he automatically turns into a beast. In order to achieve this I've thought about declaring a new class that inherits from BaseItem for each item. Each descendant would override some methods (like void OnConsume()), to change the base behavior. This works fine, but when it comes to inventory management, I have some issues. The actual inventory will have to work with BaseItem components only (for obvious reasons, as it's an enumerable collection of objects of the same type); casting any descendant to the base class is possible, so no problems in adding items to the inventory. But how can I keep track of the descendant's type (class) for each item in the inventory? And how to perform the descendant's OnConsume from withint he inventory, for each item? Let me know if you can think of a better solution than mine, or if you can think of a solution to my problem only. Development is done in C#, inside Unity 3.5. Thanks!

• Linux distro for software development support?

  - by Xie Jilei

  I've spent too much time on setup & maintain a development server, which contains following tools: Common services like SSH, BIND, rsync, etc. Subversion, Git. Apache server, which runs CGit, Trac, Webmin, phpmyadmin, phppgadmin, etc. Jetty, which runs Archiva and Hudson. Bugzilla. PostgresSQL server, MySQL server. I've created a lot of Debian packages, like my-trac-utils, my-bugzilla-utils, my-bind9-utils, my-mysql-utils, etc. to make my life more convenient. However, I still feel I need a lot more utils. And I've spent a lot of time to maintain these packages, too. I think there maybe many developers doing the same things. As tools like subversion, git, trac are so common today. It's not to hard to install and configure each of them, but it took a long time to install them all. And it's time consuming to maintain them. Like backup the data, plot the usage graph and generate web reports. (gitstat for example) So, I'd like to hear if there exist any pre-configured distro for Development Server purpose, i.e., something like BackTrack for hackers?

• Rendering a big game universe - bitmaps or vector graphics?

  - by user1641923

  I am new to an Android development, though I have much experience with Java, C++, PHP programming and a bit experience with vector graphics too (basic 3d Studio Max, Flash, etc). I am starting to work on an Android game. It is going to be a 2D space shooter/RPG, and I am not going to use any game engines and any 3D party libs. I really want to create a very large game universe, or even pseudo-infinite (without visible borders, as if it were a 2D projection of a sphere). It should include 10-12 clusters of 7-8 planets/other space objects and random amount of single asteroids/comets, which player can interact with and also not interactive background. I am looking for a least complicated aproach to create such a universe. My current ideas are: Simply create bitmaps with space scenery background so that they can be tiled seamlessly repeated and construct my 2D universe of this tiles, then place interactive objects (planets, other spaceships) on it. Using vector graphics. I would have a solid color background, some random background objects and gradients here and there. My problems here: Lack of knowledge of how well vector graphics is integrated in Android. Performance? Memory usage? Does Android manage big bitmaps well? Do all of the bitmaps have to be in memory during all game process? I am interested in technical details regarding each of the ideas and a suggestion, which I should go with.

• Reproducible freezes with on an AMD fusion (e350) sony vaio

  - by doycho

  So a week ago I bought it and I've been struggling to make the Ubuntu which I installed stable. There's one thing that makes my life miserable, though. There's this easily reproducible freeze when I start some kind of video. So here is what happens: Everything works fine for some time I start vlc/mplayer/flashplayer/totem with something to watch In few minutes time I lose the sound (nothing in the logs at this point) At that time the video app instantly allocates all the memory and its CPU usage skyrockets. Total freeze. I can move the cursor around for few seconds and sometimes even switch to another app. But ultimately there comes the time I can't do anything - can't kill X with ctrl+alt+backspace (I have it enabled), can't switch to any other console (ctrl+alt+f1-6), can't connect to the machine via ssh. The only way to restart it is the ctrl+alt+SysRq+UABI magic :) What discourages me most is the fact I can't see anything in the logs. The only error I've noticed is Jun 19 17:00:37 serenity kernel: [ 1506.350676] software-center[17581]: segfault at 30 ip 00007fd3631b814c sp 00007fff18a6fa10 error 4 in libgtk-x11-2.0.so.0.2400.4[7fd362f7d000+436000]. I've been searching through the Xorg log, kernel logs, syslog. If you have any idea how I can get more debug info I'll be glad to try them. Things I've tried: Changing drivers - the open source one, the proprietary driver xorg-edgers' ppa - https://launchpad.net/~xorg-edgers/+archive/ppa changing to the last stable kernel (2.6.39) Some notes: It my be irrelevant but the sound is constantly stuttering. This probably is a separate issue though I've found that if I start more video/sound apps the freeze happens faster.

• Mapping dynamic buffers in Direct3D11 in Windows Store apps

  - by Donnie

  I'm trying to make instanced geometry in Direct3D11, and the ID3D11DeviceContext1->Map() call is failing with the very helpful error of "Invalid Parameter" when I'm attempting to update the instance buffer. The buffer is declared as a member variable: Microsoft::WRL::ComPtr<ID3D11Buffer> m_instanceBuffer; Then I create it (which succeeds): D3D11_BUFFER_DESC instanceDesc; ZeroMemory(&instanceDesc, sizeof(D3D11_BUFFER_DESC)); instanceDesc.Usage = D3D11_USAGE_DYNAMIC; instanceDesc.ByteWidth = sizeof(InstanceData) * MAX_INSTANCE_COUNT; instanceDesc.BindFlags = D3D11_BIND_VERTEX_BUFFER; instanceDesc.CPUAccessFlags = D3D11_CPU_ACCESS_WRITE; instanceDesc.MiscFlags = 0; instanceDesc.StructureByteStride = 0; DX::ThrowIfFailed(d3dDevice->CreateBuffer(&instanceDesc, NULL, &m_instanceBuffer)); However, when I try to map it: D3D11_MAPPED_SUBRESOURCE inst; DX::ThrowIfFailed(d3dContext->Map(m_instanceBuffer.Get(), 0, D3D11_MAP_WRITE, 0, &inst)); The map call fails with E_INVALIDARG. Nothing is NULL incorrectly, and this being one of my first D3D apps I'm currently stumped on what to do next to track it down. I'm thinking I must be creating the buffer incorrectly, but I can't see how. Any input would be appreciated.

• Are bad backlinks causing thousands of 404 and 410 errors in webmaster tools?

  Our webmaster tools account is showing 250.000 errors related with weird links from other sites.

Why the tag is being generated if no link was added to the other site? What should we do with these errors? 301? 410 gone? I have read all similar Q&A here but none of them seems to solve our problem. It is not likely to be a bad ad (Inspected them all). Maybe some all content which google decided to recrawl suddenly? Maybe third parties bad SEO policy? Maybe all of them?

• What partition to use to keep data files in Ubuntu?

  - by Martin Lee

  I have been using Ubuntu for a few years and usually my partition set up was the following: Ext3 or Ext4 partition for the system itself (20 GB); A 10 GB swap partition; a big FAT32 partition to store movies, photos, work stuff, etc. (depends on the capacity of the disk, but usually it is what is left from Ext3+Swap, currently it is more than 200 GB). Does this setup sound right? I am considering to switching to one big Ext3 partition now, because the problem with Fat32 in Ubuntu has not gone anywhere: for example, right now I can access my 'big' partition with a 'Data' label only through /media/_themes?END. Pretty strange name for a partition, isn't it? some Linux software fail to read/write on this partition. For example, if I want to play around with rebar and build/make/compile things on this FAT32 partition, it will always complain about permissions and won't work (the same goes for many other kinds of software); it is not stable, I can not refer to some files on this FAT32 partition, because after the next reboot it will be called not '_themes?END', but something else. On the other side I usually begin to run out of space on the Ext3 partition after a few months of usage. So, the question is - what is the best setup of partitions for an Ubuntu system? Should a FAT32 partition be used at all?

• Book: DevOps for Developers

  - by Tori Wieldt

  We all know development and operations often act like silos, with "Just throw it over the wall!" being the battle cry. Many organizations unwittingly contribute to gaps between teams, with management by (competing) objectives; a clash of Agile practices vs. more conservative approaches; and teams using different sets of tools, such as Nginx, OpenEJB, and Windows on developers' machines and Apache, Glassfish, and Linux on production machines. At best, you've got sub-optimal collaboration, at worst, you've got the Hatfields and the McCoys.  The book DevOps for Developers helps bridge the gap between development and operations by aligning incentives and sharing approaches for processes and tools. It introduces DevOps as a modern way of bringing development and operations together. It also means to broaden the usage of Agile practices to operations to foster collaboration and streamline the entire software delivery process in a holistic way. Some single aspects of DevOps may not be new, for example, you may have used the tool Puppet for years already, but with a new mindset ("my job is not just to code, it's to serve the customer in the best way possible") and a complete set of recipes, you'll be well on your way to success. DevOps for Developers also by provides real-world use cases (e.g., how to use Kanban or how to release software). It provides a way to be successful in the real development/operations world. DevOps for Developers is written my Michael Hutterman, Java Champion, and founder of the Cologne Java User Group. "With DevOps for Developers, developers can learn to apply patterns to improve collaboration between development and operations as well as recipes for processes and tools to streamline the delivery process," Hutterman explains.

New setting is " + configSectionAdapter.ConfigSection.MyConfigSetting); }; Console.WriteLine("The initial setting is " + configSectionAdapter.ConfigSection.MyConfigSetting); Console.ReadLine(); } }  The meat: public class ConfigurationSectionAdapter<T> : IDisposable where T : ConfigurationSection { private readonly string _configSectionName; private FileSystemWatcher _fileWatcher; public ConfigurationSectionAdapter(string configSectionName) { _configSectionName = configSectionName; StartFileWatcher(); } private void StartFileWatcher() { var configurationFileDirectory = new FileInfo(Configuration.FilePath).Directory; _fileWatcher = new FileSystemWatcher(configurationFileDirectory.FullName); _fileWatcher.Changed += FileWatcherOnChanged; _fileWatcher.EnableRaisingEvents = true; } private void FileWatcherOnChanged(object sender, FileSystemEventArgs args) { var changedFileIsConfigurationFile = string.Equals(args.FullPath, Configuration.FilePath, StringComparison.OrdinalIgnoreCase); if (!changedFileIsConfigurationFile) return; ClearCache(); OnConfigSectionChanged(); } private void ClearCache() { ConfigurationManager.RefreshSection(_configSectionName); } public T ConfigSection { get { return (T)Configuration.GetSection(_configSectionName); } } private System.Configuration.Configuration Configuration { get { return ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None); } } public delegate void ConfigChangedHandler(); public event ConfigChangedHandler ConfigSectionChanged; protected void OnConfigSectionChanged() { if (ConfigSectionChanged != null) ConfigSectionChanged(); } public void Dispose() { _fileWatcher.Changed -= FileWatcherOnChanged; _fileWatcher.EnableRaisingEvents = false; _fileWatcher.Dispose(); } }

• Resize a pendrive Linux?

  - by user11239

  I'm running Ubuntu from USB media, which has a drive capacity of 250 GB, all existing as one FAT32 partition. However, when I created the bootable Ubuntu drive, only 4.79 GB were allocated for usage. Rather than put files directly into the /cdrom where the drive is mounted, I want to expand what is listed here in aufs to be at least 200 GB. I'm hopeful that I can do this live. Output of df : Filesystem 1K-blocks Used Available Use% Mounted on aufs 4051904 4050108 0 100% / none 1542852 284 1542568 1% /dev /dev/sdb1 244076800 4901648 239175152 3% /cdrom /dev/loop0 688000 688000 0 100% /rofs none 1547840 1496 1546344 1% /dev/shm tmpfs 1547840 4828 1543012 1% /tmp none 1547840 80 1547760 1% /var/run none 1547840 0 1547840 0% /var/lock none 1547840 0 1547840 0% /lib/init/rw Output of fdisk -l : Disk /dev/sdb: 250.1 GB, 250059350016 bytes 255 heads, 63 sectors/track, 30401 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00083fe4 Device Boot Start End Blocks Id System /dev/sdb1 * 1 30401 244196001 c W95 FAT32 (LBA) So basically what I want to do is get /dev/sdb1 to be entirely, or almost entirely read as aufs. I'm confused over how to do this, as the file systems are all part of /dev/sdb1 on one big partition, rather than separate partitions for separate file systems.

• AsyncBridge? Async on .NET 4.0 using VS11

  - by Alex.Davies

  I've just found something quite cool. It's a code snippet that lets you use the real VS 11 C#5 compiler to write code that uses the async and await keywords, but to target .NET 4.0. It was published by Daniel Grunwald (from SharpDevelop).That means I can stop using the Async CTP for VS2010, which is not at all supported anymore, and a pain to install if you have windows updates turned on. Obviously I couldn't ask all my users to install .NET 4.5 beta, but .NET Demon is a VS 2010 extension, so we already have .NET 4.0. At the time of writing, VS11 is in beta still, but hopefully it's stable enough for my team to use!I would have written the code myself, but I had the wrong impression that the C# 5 beta compiler only looked in mscorlib for the helper classes it needs to implement async methods. Turns out you can provide them yourself. You can get the code here: https://gist.github.com/1961087You just add it to your project, and the compiler will apparently pick it up and use it to implement async/await. I'm at my parents' place for Easter without access to a machine with VS 11 to try it out. Let me know whether you get it to work!This reminds me of LINQBridge, which let us use C# 3 LINQ, but only require .NET 2. We should stick up a webpage to explain, with a nice easy dll, put it in nuget, and call it AsyncBridge.If you were really enthusiastic, you could re-implement the skeleton of the Task Parallel Library against .NET 2 to use async/await without even requiring .NET 4. Our usage stats suggest that practically everyone that uses Red Gate tools already has .NET 4 installed though, so I don't think I'll go to the effort.

• What are the hard and fast rules for Cache Control?

  - by Metalshark

  Confession: sites I maintain have different rules for Cache Control mostly based on the default configuration of the server followed up with recommendations from the Page Speed & Y-Slow Firefox plug-ins and the Network Resources view in Google's Speed Tracer. Cache-Control is set to private/public depending on what they say to do, ETag's/Last-Modified headers are only tinkered with if Y-Slow suggests there is something wrong and Vary-Accept-Encoding seems necessary when manually gziping files for Amazon CloudFront. When reading through the material on the different options and what they do there seems to be conflicting information, rules for broken proxies and cargo cult configurations. Any of the official information provided by the analysis tools mentioned above is quite inaccessible as it deals with each topic individually instead of as a unified strategy (so there is no cross-referencing of techniques). For example, it seems to make no sense that the speed analysis tools rate a site with ETag's the same as a site without them if they are meant to help with caching. What are the hard and fast rules for a platform agnostic Cache Control strategy? EDIT: A link through Jeff Atwood's article explains Caching in superb depth. For the record though here are the hard and fast rules: If the file is Compressed using GZIP, etc - use "cache-control: private" as a proxy may return the compressed version to a client that does not support it (the browser cache will hold files marked this way though). Also remember to include a "Vary: Accept-Encoding" to say that it is compressible. Use Last-Modified in conjunction with ETag - belt and braces usage provides both validators, whilst ETag is based on file contents instead of modification time alone, using both covers all bases. NOTE: AOL's PageTest has a carte blanche approach against ETags for some reason. If you are using Apache on more than one server to host the same content then remove the implicitly declared inode from ETags by excluding it from the FileETag directive (i.e. "FileETag MTime Size") unless you are genuinely using the same live filesystem. Use "cache-control: public" wherever you can - this means that proxy servers (and the browser cache) will return your content even if the rest of the page needs HTTP authentication, etc.
