• What are the best strategies for selling Android apps?

  - by Rob S.

  I'm a young developer hoping to sell my apps I made for Android soon. My applications are basically 99% finished so I'm investigating what would be the best marketing strategy to use to sell my apps. I'm sure the brilliant minds here can give me some great advice. I'm particularly interested in your thoughts on the following points (especially from experienced Android developers): Is it more profitable to sell an app for free with ads or to sell an app without ads for a price? Perhaps a combination of a free ad version and a paid ad-free version? If you give away an app for free with ads on it is it ethical to decline bending over backwards to support it? How much does piracy actually affect potential sales? Should any effort be put towards preventing it? Can you still make a profit off your application if you make it open source? Could you perhaps make more of a profit from the attention you would get by doing so? Is Google's Android Marketplace really the best place to release Android apps? It is worthwhile enough to maintain a developer blog or website to keep users updated on your development progress and software releases? Any other suggestions you could give me to maximize profit meanwhile keeping users happy and coming back for more would also be greatly appreciated. While I appreciate general tips and tricks, I'd like to ask that if possible you please go the extra step and show how they specifically apply to selling Android apps. Marketing statistics, developer retrospect, and any additional experience you can share from your time selling Android apps is what I would love to see most. Thank you very much in advance for your time. I truly appreciate all the responses I receive.

• Migrating Forms to Java or ADF, the truth and no FUD

  - by Grant Ronald

  The question about migrating Forms to Java (or ADF or APEX) comes up time and time again.  I wanted to pull some core information together in a single blog post to address this question. The first question I always ask is "WHY" - Forms may still be a viable option for you so "if it ain't broke don't fix it".  Bottom line is whatever anyone tells you, its going to be a considerable effort and cost to migrate from Forms to something else so the business is going to want to know WHY you spend all those hard earned dollars switching from something that might have been serving you quite adequately. Second point, if you are going to switch, I would encourage you NOT to look at building a Forms clone.  So many times I see people trying to build an ADF application and EXACTLY mimic the Forms model - ADF is NOT a Forms clone.  You should be building to the sweet spot of your target technology, not your 20 year old client/server technology.  This is also the chance for the business to embrace change, so maybe look at new processes, channels and technology options that weren't available when you first developed your Forms applications. To help you understand what is involved, I've put together a number of resources. Thinking about migration of Forms to Java, ADF or APEX, read this to prepare yourself Oracle Forms to ADF: When, Why and How - this gives you an overview of our vision, directly from Oracle Product Management Redeveloping a Forms Application with Oracle JDeveloper and Oracle ADF.  This is a conference session from myself and Lynn Munsinger on how ADF can be used in a Forms migration/rewrite As someone who manages both Forms and ADF Product Management teams, I've a foot in either camp and am happy to see you use either tool.  However, I want you to be able to make an informed decision.  My hope is that there information sources will help you do that.

• Fight for your rights as a video gamer.

  - by Chris Williams

  Soon, the U.S. Supreme Court may decide whether to hear a case that could have a lasting impact on computer and video games. The case before the Court involves a law passed by the state of California attempting to criminalize the sale of certain computer and video games. Two previous courts rejected the California law as unconstitutional, but soon the Supreme Court could have the final say. Whatever the Court's ruling, we must be prepared to continue defending our rights now and in the future. To do so, we need a large, powerful movement of gamers to speak with one voice and show that we won't sit back while lawmakers try to score political points by scapegoating video games and treating them differently than books, movies, and music. If the Court decides to hear the case, we're going to need thousands of activists like you who can help defend computer and video games by writing letters to editors, calling into talk radio stations, and educating Americans about our passion for and appreciation of computer and video games. You can help build this movement right now by inviting all your friends and fellow gamers to join the Video Game Voters Network. Use our simple tool to send an email to everyone you know asking them to stand up for gaming rights: http://videogamevoters.org/movement You can also help spread the word through Facebook and Twitter, or you can simply forward this email to everyone you know and ask them to sign up at videogamevoters.org. Time after time, courts continue to reject politicians' efforts to restrict the sale of computer and video games. But that doesn't mean the politicians will stop trying anytime soon -- in fact, it means they're likely to ramp up their efforts even more. To stop them, we must make it clear that gamers will continue to stand up for free speech -- and that the numbers are on our side. Help make sure we're ready and able to keep fighting for our gaming rights. Spread the word about the Video Game Voters Network right now: http://videogamevoters.org/movement Thank you. -- Video Game Voters Network

• How to show or direct a business analyst to a data modelling subject?

  - by AaronLS

  Our business analysts pushed hard to collect data through a spreadsheet. I am the programmer responsible for importing that data. Usually when they push hard for something like this, I never know how well it will work out until a few weeks later when I have time assigned to work on the task of programming the import of the data. I have tried to do as much as possible along the way, named ranges, data validations, etc. But I usually don't have time to take a detailed look at all the data and compare to the destination in the database to determine how well it matches up. A lot of times there will be maybe a little table of items that somehow I have to relate to something else in the database, but there are not natural or business keys present that would allow me to do so. Make the best of this, trying to write something that can compare strings and make a best guess at it and then go through the effort of creating interfaces for a user to match the imported data to the destination. I feel like if the business analyst was actually creating a data model, they would be forced to think about these relationships, and have an appreciation for the need of natural or business keys to be part of the spreadsheet for the purposes of smoothly importing the data. The closest they come to business analysis is a big flat list of fields, and that would be fine if it were like any other data dictionary and include data types+relationships, but it isn't. They are just a bunch of names. No indication of what type of data they might hold, and it is up to me to guess. When I have pushed for more detail, they say that it is just busy work. How can I explain the importance of data modelling? How can I tell them what it is and how to do it? It feels impossible, because they don't have an appreciation for its importance. They do however, usually have an interest in helping out in whatever way they can, it's just this in particular has never gotten a motivated response.

• Advantages and Disadvantages of the Waterfall Methodology

  In my personal opinion I believe the waterfall method is one of the worst methodologies to use when developing larger systems because it leaves is no room for mistakes. As the name implies the waterfall methodology does not allow  for projects to go back up stream to recover from design errors, missing and/or limited requirements. In addition, hidden bugs are not usually found until the testing phase. This can prove to be very costly and time consuming to the developer and the client. According to NCycles.com, the waterfall methodology structures a project into separate stages with defined deliverables from each phase. Define Design Code Test Implement Document and Maintain The advantages found by Ncycle.com to this methodology are: Ease in analyzing potential changes  Ability to coordinate larger teams, even if geographically distributed Can enable precise dollar budget Less total time required from Subject Matter Experts The disadvantages found by Ncycle.com to this methodology are: Lack of flexibility Hard to predict all needs in advance Intangible knowledge lost between hand-offs Lack of team cohesion Design flaws not discovered until the Testing phase References: NCycles.com  (2002).

• Add static ARP entries when network is brought up

  - by jozzas

  I have some pretty dumb IP devices on a subnet with my Ubuntu server, and the server receives streaming data from each device. I have run into a problem in that when an ARP request is issued to the device while it is streaming data to the server, the request is ignored, the cache entry times out and the server stops receiving the stream. So, to prevent the server from sending ARP requests to these devices altogether, I would like to add a static ARP entry for each, something like arp -i eth2 -s ip.of.the.device mac:of:the:device But these "static" ARP entries are lost if networking is disabled / enabled or if the server is rebooted. Where is the best place to automatically add these entries, preferably somewhere that will re-add them every time the interface eth2 is brought up? I really don't want to have to write a script that monitors the output of arp and re-adds the cache entries if they're missing. Edit to add what my final script was: Created the file /etc/network/if-up.d/add-my-static-arp With the contents: #!/bin/sh arp -i eth0 -s 192.168.0.4 00:50:cc:44:55:55 arp -i eth0 -s 192.168.0.5 00:50:cc:44:55:56 arp -i eth0 -s 192.168.0.6 00:50:cc:44:55:57 And then obviously add the permission to allow it to be executed: chmod +x /etc/network/if-up.d/add-my-static-arp And these arp entries will be manually added or re-added every time any network interface is brought up.

• How to find keycodes for Fn + keys in Ubuntu 11.10

  - by budwiser

  I'm trying to find out the keycode for Fn+? keypress (left arrow). Xev outputs FocusOut event, serial 36, synthetic NO, window 0x3c00001,    mode NotifyGrab, detail NotifyAncestor FocusIn event, serial 36, synthetic NO, window 0x3c00001,    mode NotifyUngrab, detail NotifyAncestor KeymapNotify event, serial 36, synthetic NO, window 0x0,    keys:  4294967213 0   0   0   0   0   0   0   0   0   0   0   0   0   0   0              0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   If it is telling me the keycode here, I'm not able to interpret it so help would be appreciated. I'm also curious for finding out if it's possible to bind something to Fn+Del but when trying out this combination, Xev outputs KeyPress event, serial 36, synthetic NO, window 0x3c00001, root 0xad, subw 0x0, time 1984903, (-666,480), root:(53,533), state 0x0, keycode 119 (keysym 0xffff, Delete), same_screen YES, XLookupString gives 1 bytes: (7f) " " XmbLookupString gives 1 bytes: (7f) " " XFilterEvent returns: False KeyRelease event, serial 36, synthetic NO, window 0x3c00001, root 0xad, subw 0x0, time 1985008, (-666,480), root:(53,533), state 0x0, keycode 119 (keysym 0xffff, Delete), same_screen YES, XLookupString gives 1 bytes: (7f) " " XFilterEvent returns: False which is exactly the same as pressing del without Fn. So, summary for short How can I find keycode for Fn+? (left arrow)? Is it even possible to bind something to Fn+Del or am I facing windmills here?

• How do I account for changed or forgotten tasks in an estimate?

  - by Andrew

  To handle task-level estimates and time reporting, I have been using (roughly) the technique that Steve McConnell describes in Chapter 10 of Software Estimation. Specifically, when the time comes for me to create task-level estimates (right before coding begins on a project), I determine the tasks at a fairly granular level so that, whenever possible, I have no tasks with a single-point, 50%-confidence estimate greater than four hours. That way, the task estimation process helps with constructing the software while helping me not to forget tasks during estimation. I come up with a range of hours possible for each task also, and using the statistical calculations that McConnell describes along with my historical accuracy data, I can generate estimates at other confidence levels when desired. I feel like this method has been working fairly well for me. We are required to put tasks and their estimates into TFS for tracking, so I use the estimates at the percentage of confidence I am told to use. I am unsure, however, what to do when I do forget a task, or I end up needing to do work that does not neatly fall within one of the tasks I estimated. Of course, trying to avoid this situation is best, but how do I account for forgotten/changed tasks? I want to have the best historical data I can to help me with future estimates, but right now, I basically am just calculating whether I made the 50%-confidence estimate and whether I made it inside the ranged estimate. I'll be happy to clarify what I'm asking if needed -- let me know what is unclear.

• What are the maths behind 'Raiden 2' purple laser?

  - by Aybe

  The path of the laser is affected by user input and enemies present on the screen. Here is a video, at 5:00 minutes the laser in question is shown : Raiden II (PS) - 1 Loop Clear - Part 2 UPDATE Here is a test using Inkscape, ship is at bottom, the first 4 enemies are targeted by the plasma. There seems to be a sort of pattern. I moved the ship first, then the handle from it to form a 45° angle, then while trying to fit the curve I found a pattern of parallel handles and continued so until I reached the last enemy. Update, 5/26/2012 : I started an XNA project using beziers, there is still some work needed, will update the question next week. Stay tuned ! Update : 5/30/2012 : It really seems that they are using Bézier curves, I think I will be able to replicate/imitate a plasma of such grade. There are two new topics I discovered since last time : Arc length, Runge's phenomenon, first one should help in having a linear movement possible over a Bézier curve, second should help in optimizing the number of vertices. Next time I will put a video so you can see the progress 8-)

• Why is my root filesystem always scanned at boot?

  - by luri

  I always have a pause at boot saying my filesystems are being checked (with a "press C to cancel" note, too). Actually (seeing boot.log) I think it's the / fs, which is located at /dev/sdb5 Several questions altoghether, here (hope this does not break any rule): Is this normal? Can I (or even should I) prevent this anyhow? According to boot.log (below) the fs does not seem to be 'clean', or, at least, it's in an state or condition that makes fsck always can it for errors for a while (just a few seconds). How can I fix it? Edit: This is my boot.log: fsck desde util-linux-ng 2.17.2 udevd[515]: can not read '/etc/udev/rules.d/z80_user.rules' /dev/sdb5: 249045/32841728 ficheros (0.3% no contiguos), 20488485/131338752 bloques init: ureadahead-other main process (1111) terminated with status 4 init: ureadahead-other main process (1116) terminated with status 4 Password: * Starting AppArmor profiles [160G Skipping profile in /etc/apparmor.d/disable: usr.bin.firefox [154G[ OK ] * Setting sensors limits [160G [154G[ OK ] And this is dumpe2fs results for the filesystem being checked (well, the relevant part of the log): Filesystem volume name: <none> Last mounted on: / Filesystem UUID: 42509bf9-f3e6-460a-8947-ec0f5c1fbcc8 Filesystem magic number: 0xEF53 Filesystem revision #: 1 (dynamic) Filesystem features: has_journal ext_attr resize_inode dir_index filetype needs_recovery extent flex_bg sparse_super large_file huge_file uninit_bg dir_nlink extra_isize Filesystem flags: signed_directory_hash Default mount options: (none) Filesystem state: clean Errors behavior: Continue Filesystem OS type: Linux Inode count: 32841728 Block count: 131338752 Reserved block count: 6566937 Free blocks: 110850356 Free inodes: 32592701 First block: 0 Block size: 4096 Fragment size: 4096 Reserved GDT blocks: 992 Blocks per group: 32768 Fragments per group: 32768 Inodes per group: 8192 Inode blocks per group: 512 Flex block group size: 16 Filesystem created: Fri Dec 10 19:44:15 2010 Last mount time: Mon Feb 14 17:00:02 2011 Last write time: Mon Feb 14 16:59:45 2011 Mount count: 1 Maximum mount count: 33 Last checked: Mon Feb 14 16:59:45 2011 Check interval: 15552000 (6 months) Next check after: Sat Aug 13 17:59:45 2011 Lifetime writes: 331 GB Reserved blocks uid: 0 (user root) Reserved blocks gid: 0 (group root) First inode: 11 Inode size: 256 Required extra isize: 28 Desired extra isize: 28 Journal inode: 8 First orphan inode: 28049496 Default directory hash: half_md4 Directory Hash Seed: d3d24459-514b-4413-b840-e970b766095b Journal backup: inode blocks Journal features: journal_incompat_revoke Tamaño de fichero de transacciones: 128M Journal length: 32768 Journal sequence: 0x0005e0c4 Journal start: 1 This is the relevant (at least I think this is the fs being checked) line in fstab: #Entry for /dev/sdb5 : UUID=42509bf9-f3e6-460a-8947-ec0f5c1fbcc8 / ext4 errors=remount-ro 0 1

• mpd conflicting with other applications -- taking control of pulse?

  - by Jamie Schembri

  Simple explanation If mpd is playing and sound attempts to play through another application, x, sound from x will not be output. If sound from another application, x, is playing and mpd then attempts to play, no sound will be output from mpd whilst sound from x continues to play. Details I first noticed this problem with Flash, and this continues to be the most common scenario. I posted a question about this before realising it was not strictly Flash-related, but instead is something to do with mpd. My biggest frustration comes from trying to get mpd working again, as I can't seem to pin down any method. Sometimes pulseaudio -k seems to help, other times sudo /etc/init.d/mpd restart, others killing Chromium (due to Flash) with SIGTERM. Most of the time it's a combination of the above. I think this might be because I run mpd as another user and use pulseaudio. It is not run as root or current user. Also, mpd is compiled with pulse support. I have tried numerous things, however I honestly couldn't recite what, as it has been some time since. I'd rather not go poking around without some direction, but I'd be really happy to fix this problem once and for all. mpd.conf Simplified by removing comments/blank lines. music_directory "/var/lib/mpd/music" playlist_directory "/var/lib/mpd/playlists" db_file "/var/lib/mpd/tag_cache" log_file "/var/log/mpd/mpd.log" pid_file "/var/run/mpd/pid" state_file "/var/lib/mpd/state" user "mpd" bind_to_address "wilson" input { plugin "curl" } audio_output { type "pulse" name "My Pulse Output" } filesystem_charset "UTF-8" id3v1_encoding "UTF-8" Question For the sake of keeping this a question: does anyone know what is causing this, or how to fix it?

• How to go from mainstream to indie development?

  - by Salano Software

  I'm currently working as a game programmer for a AAA-level developer and publisher - which falls into the 'nice problem to have' category, I know, except that I'm growing more and more disenchanted with the direction of both the company and the AAA portion of the industry as a whole. I don't see any games on the studio's calendar for the next several years that I'm actually interested in working on; it looks like a continuing parade of sequels, license extensions and largely-derivative work. Which isn't to say that there won't be interesting things to do on those projects; but more and more I find myself wanting to do something fundamentally different. It seems like the market's never been better for smaller-scale projects, and I'd love to jump into that (and I've done small demos for Android and have started digging into iOS), but I obviously can't put anything out while I'm working for the company, and I'm concerned that I shouldn't even do substantial development in my spare time on anything I'd eventually like to release on my own. At the same time, I'm leery of leaving the job I've got for hopefully-obvious reasons, especially without a specific plan in place. Has anyone out there got experience with 'going indie' out of a mainstream job, and does anyone have specific suggestions as to what the best approach is and what I should specifically be thinking about or be careful of?

• Google Programmers

  - by seth

  As a soon-to-be software engineer, I have studied some languages during my time in college. I can name C, C++, Java, Scheme, Ruby, PHP, for example. However, one of the main principles in my college (recognized by many as the best in my country) is to teach us how to learn for ourselves and how to search the web when we have a doubt. This leads to a proactive attitude, when I need something, I go get it and this has worked so far for me. Recently, I started wondering though, how much development would I be able to do without internet access. The answer bugged me quite a bit. I know the concept of the languages, mostly I know what to do, but I was amazed by how "slow" things were without having the google to help in the development. The problem was mostly related to specific syntax but it was not without some effort that i solved some of the SPOJ problems in C++. Is this normal? Should I be worried and try to change something in my programming behaviour? UPDATE: I'll give a concrete example. Reading and writing to a file in java. I have done this about a dozen times in my life, yet every time I need to do it, I end up googling "read file java" and refreshing my memory. I completely understand the code, i fully understand what it does. But I am sure, that without google, it would take me a few tries to read and write correctly (if I had to sit in front of the screen with a blank page and write this without consulting any source whatsoever).

• Speed up loading of test results from builds in Visual Studio

  - by Jakob Ehn

  I still see people complaining about the long time it takes to load test results from a TFS build in Visual Studio. And they make a valid point, it does take a very long time to load the test results, even for a small number of tests. The reason for this is that the test results is not just the result of the test run but also all the binaries that were part of the test run. This often also means that the debug symbols (*.pdb) will be downloaded to your local machine. This reason for this behaviour is that it letsyou re-run the tests locally. However, most of the times this is not what the developer will do, they just want to know which tests failed and why. They can then fix the tests and rerun them locally. It turns out there is a way to load only the test results, which is much faster. The only tricky bit is to find the location of the .trx file that is generated during the build. Particularly in TFS 2010 where you often have multiple build agents, which of corse results in different paths to the trx file. Note: To use this you must have read permission to the build folder on the build agent where the build was executed. Open the build result for the build Click View Log Locate the part where MSTest is invoked. When using test containers, it looks like this:   Note: You can actually search in the log window, press Ctrl+F and you will get a little search box at the bottom. Nice! On the MSTest command line call, locate the /resultsfileroot parameter, which points to the folder where the test results are stored Note that this path is local for the build server, so you need to replace the drive letter with the server name: D:\Builds\Project\TestResults to \Project\TestResults">\\<BuildServer>\Project\TestResults Double-click on the .trx file and you will notice that it loads much faster compared to opening it from the build log window

• Why We Need UX Designers

  - by Tim Murphy

  Ok, so maybe this is really why I need UX designers.  While I have always had an interest in photography and can appreciate a well designed user interface putting one together is an entirely different endeavor.  Being color blind doesn’t help, but coming up with ideas is probably the biggest portion of the issue.  I can spot things that just don’t look like they work right, but what will? UX designers is an area that most companies do not spend much if any resources.  As they say, you only get one chance to make a first impression and and a poorly designed site or application is a bad first impression.  Given that they you would think that companies would invest more in appearance and usability. One of two things need to be done to rectify this issue.  Either we need to start educating our developers on user experience and design or we need to start finding ways to subsidize putting full time designers on our project teams.  Maybe it should be a time share type of situation, but something needs to be done.  As architects we need to impress on our project stakeholders the importance of User Experience and why it should be part of the budget.  If they hear it often enough eventually they may present it to you as their own idea. del.icio.us Tags: User Experience,UX,Application Design

• How to decide on a price for the project as a freelancer

  - by Shekhar_Pro

  I have seen similar question on this SE site but none comes close to a sure shot answer and many are rather subjective. So i am taking a website as an example to be more objective for you to decide its development price i should quote for the complete work.I would like to have specific figures. In past I have developed many projects for my classmates (Computer science and few .net) when i was in college and there i just arbitrarily quoted the price i will take depending on my mood and customer's ability to pay.. usually ranging from Rs.500 (about $10 USD) to Rs. 1500 (about $30 USD). I have also developed few websites but that was open-source and free. But this time impressed by my work i have got a client that wants to get a website developed similar to this: [ http://www.jeetle.in/ ]. So taking this website as an example tell me how much should i charge for complete work from designing to payment gateway implementation (Excluding the charge the payment gateway provider will take). Few information you might like to consider. I am the only developer on this project if that makes any difference. And i would be using ASP.Net and MSSQL Express for server side processing and jQuery on client. Time period for development offered is about 4 to 6 Weeks. Its like i know my work but not how much I'm worth

• Positioning a sprite in XNA: Use ClientBounds or BackBuffer?

  - by Martin Andersson

  I'm reading a book called "Learning XNA 4.0" written by Aaron Reed. Throughout most of the chapters, whenever he calculates the position of a sprite to use in his call to SpriteBatch.Draw, he uses Window.ClientBounds.Width and Window.ClientBounds.Height. But then all of a sudden, on page 108, he uses PresentationParameters.BackBufferWidth and PresentationParameters.BackBufferHeight instead. I think I understand what the Back Buffer and the Client Bounds are and the difference between those two (or perhaps not?). But I'm mighty confused about when I should use one or the other when it comes to positioning sprites. The author uses for the most part Client Bounds both for checking whenever a moving sprite is of the screen and to find a spawn point for new sprites. However, he seems to make two exceptions from this pattern in his book. The first time is when he wants some animated sprites to "move in" and cross the screen from one side to another (page 108 as mentioned). The second and last time is when he positions a texture to work as a button in the lower right corner of a Windows Phone 7 screen (page 379). Anyone got an idea? I shall provide some context if it is of any help. Here's how he usually calls SpriteBatch.Draw (code example from where he positions a sprite in the middle of the screen [page 35]): spriteBatch.Draw(texture, new Vector2( (Window.ClientBounds.Width / 2) - (texture.Width / 2), (Window.ClientBounds.Height / 2) - (texture.Height / 2)), null, Color.White, 0, Vector2.Zero, 1, SpriteEffects.None, 0); And here is the first case of four possible in a switch statement that will set the position of soon to be spawned moving sprites, this position will later be used in the SpriteBatch.Draw call (page 108): // Randomly choose which side of the screen to place enemy, // then randomly create a position along that side of the screen // and randomly choose a speed for the enemy switch (((Game1)Game).rnd.Next(4)) { case 0: // LEFT to RIGHT position = new Vector2( -frameSize.X, ((Game1)Game).rnd.Next(0, Game.GraphicsDevice.PresentationParameters.BackBufferHeight - frameSize.Y)); speed = new Vector2(((Game1)Game).rnd.Next( enemyMinSpeed, enemyMaxSpeed), 0); break;

• Is there a process-oriented IDE ?

  - by Raveline

  My problem is simple : when I'm programming in an OO paradigm, I'm often having part of a main business process divided in many classes. Which means, if I want to examine the whole functional chain that leads to the output, for debugging or for optimization research, it can be a bit painful. So I was wondering : is there an IDE that let you put a "process tag" on functions coming from different objects, and give you a view of all those functions having the same tag ? edit : To give an example (that I'm making up completely, sorry if it doesn't sound very realistic). Let's say we have the following business process for a HR application : receive a holiday-request by an employee, check the validity of the request, then give an alert to his boss ("one of those lazy programmer wants another day off"); at the same time, let's say the boss will want to have a table of all employee's timetable during the time the employee wants his vacations; then handle the answer of the boss, send a nice little mail to the employee ("No way, lazy bones"). Even if we get rid of everything not purely business-related (mail sending process, db handling to get the useful info, GUI functionalities, and so on), we still have something that doesn't really fit in "one class". I'd like to have an IDE that would give me the opportunity to embrace quickly, at the very least : The function handling the validation of the request by the employee; The function preparing the "timetable" for the boss; The function handling the validation of the request by the boss; I wouldn't put all those functions in the same class (but perhaps that's my mistake ?). This is where my dreamed IDE could be helpful.

• Which web framework or technologies would suit me?

  - by Suraj Chandran

  Hi, I had been working on desktop apps and server side(non web) for some time and now I am diving in to web first time. I plan to write a scalable enterprise level app. I have worked with Java, Javascript, Jquery etc. but I absolutely hate jsp. So is there any framework that focuses on developing enterprise level web apps without jsp. I liked Wicket's approach, but I think there is a little lack of support of dynamic html in it and jquery(yes i looked at wiquery). Also I feel making wicket apps scalable would take some sweat. Can Spring MVC, Struts2 etc. help me make with this with just using say Java, JavaScript, and JQuery. Or are there any other options for me like Wicket. Please do forgive if anything above looks insane, I am still working on my understanding with enterprise web apps. NOTE: If you think that I should take a different direction or approach, please do suggest!

• Ubuntu's security, Gaming, X server, situation [closed]

  - by ShortCircuit

  Little background story. So when I first heard about the NSA spying on people I wasn't surprised, it also was the reason why I switched to Ubuntu. (Full time) It had it's disadvantages when comparing to Windows and it's AAA games and other stuff. My best friend is somewhat upset about me, using full time Ubuntu, because we play a game named "Dayz (an addon for Arma II)" and WineHQ wasn't of any help. Not to mention that he keeps asking me if WineHQ can run Dayz, but he clearly doesn't understand the situation of WineHQ, that it's free, that you have to be happy with what you got at the moment. (I'm not going to dual boot because, how else is gaming on Ubuntu/Linux going to happen?) But whenever I was in a nasty situation where I could do something so simply on Windows and not/hard on Ubuntu, I always thought "It's almost virus free, It's free, No one is spying on me." My Questions: My English isn't all that good, so could some one simplify/explain what the hell is going on the below standing link? Ubuntu Spyware: What to Do? https://www.gnu.org/philosophy/ubuntu-spyware.html When will gaming on Linux/Ubuntu be a real thing? I've heard that the X server's code is a mess and that Wayland will replace X server. When/will this come reality? (I might have understood this wrong.)

• Interesting SSMS issue with waittype of PREEMPTIVE_OS_LOOKUPACCOUNTSID

  - by steveh99999

  Saw a recent issue with SQL2008 sp 1 where SQL Server Management Studio (SSMS) appeared to hang when a DBA expanded the database users tab of a database… ie like this :-   When we looked at the waittype of the SSMS session - via sys.dm_os_waiting_tasks– it was waiting on PREEMPTIVE_OS_LOOKUPACCOUNTSID. I’d not come across this waittype before, and there was very little information out on the web for it.. Looking at this issue using SQL Profiler – it them became apparent that SSMS was waiting on the function SUSER_SNAME. I did a quick test using SET STATISTICS TIME to prove it was the SUSER_SNAME function causing our issue :- SELECT * FROM sys.database_principals   -- completes in 6 milliseconds SELECT SUSER_SNAME(sid),* FROM sys.database_principals  -- completes in 188941 milliseconds. suser_sname validates a sid against Active Directory.. What I haven’t mentioned so far is that the database in question had been restored from a server on a different domain. This domain was untrusted from the current domain. However, it appeared that SSMS was still trying to validate the Windows login of each user when displaying the users list…. and taking a long time to return NULL for each user from the untrusted domain. When all users that had a login from the untrusted domain are removed from the database – this fixed the issue. To find out the users that had this issue :- SELECT name FROM sys.database_principals WHERE type_desc IN(‘WINDOWS_USER’, ‘WINDOWS_GROUP’) and SUSER_SNAME(sid) IS NULL Although I have not raised this as a case with MS – I do think this is a bug in SSMS – I do not see why windows logins should need to be validated when displaying only user details..
