• what exactly is system programming?

  - by kentjh

  I have never understood what system programming meant. The usual definition given is "...doing something close to the Os or extending Os features...". Does using Windows API directly rather than some libraries to say do file i/o make it system programming? Was writing Android OS system programming? If I write something that would expose linux kernel through a console like app on Android am I doing system programming? If I am writing software to control a washing machine am I writing system programming? I am a beginner in programming and this is confusing me to no end. Please explain contrasting it with "application programming".

• Installing software on an offline Ubuntu server

  - by Muhammad Gelbana

  Assuming that I have a server with Ubuntu server newly installed on it. I was thinking of installing the very same version on Virtual Box (Or any other virtualization software), connect it to the internet and use apt-get to only download the packages for upgrading the system and the new software such as (tomcat7, openjdk6-default-headless..etc). Then copy the downloaded packages from the archive folder to the offline server's archive folder through a USB stick. So now the virtual system won't actually be upgraded nor have any new software installed. But would running the very same apt-get commands on the offline system without the download directive -d be executed without issues ? *EDIT:*This needs to be as simple as possible because I'll have to write a guide for our client to do this on his own and so it won't be acceptable to require deep Linux knowledge to do this.

• The Future According to Films [Infographic]

  - by Jason Fitzpatrick

  Curious what the future will look like? According to movie directors, casting their lens towards the future of humanity, it’s quite a mixed bag. Check out this infographic timeline to check out the next 300,000 years of human evolution. A quick glance over the timeline shows a series of future where things can quickly go from the fun times to the end-of-the-world times. We’d like to, for example, live it up in the Futurama future of 3000 AD and not the Earth-gets-destroyed future of Titan A.E’s 3028. Hit up the link below for a high-res copy of the infographic.

• How can I optimize my development machines files/dirs?

  - by LuxuryMode

  Like any programmer, I've got a lot of stuff on my machine. Some of that stuff is projects of my own, some are projects I'm working on for my employer, others are open-source tools and projects, etc. Currently, I have my files organized as follows: /Code --/development (things I'm sort of hacking on plus maybe libraries used in other projects) --/scala (organized by language...why? I don't know!) --/android --/ruby --/employer_name -- /mobile --/android --/ios --/open-source (basically my forks that I'm pushing commits back upstream from) --/some-awesome-oss-project --/another-awesome-one --/tools random IDE settings sprinkled in here plus some other apps As you can see, things are kind of a mess here. How can I keep things organized in some sort of coherent fashion?

• Management Software in Java for Networked Bus Systems

  - by Geertjan

  Telemotive AG develops complex networked bus systems such as Ethernet, MOST, CAN, FlexRay, LIN and Bluetooth as well as in-house product developments in infotainment, entertainment, and telematics related to driver assistance, connectivity, diagnosis, and e-mobility. Devices such as those developed by Telemotive typically come with management software, so that the device can be configured. (Just like an internet router comes with management software too.) The blue AdmiraL is a development and analysis device for the APIX (Automotive Pixel Link) technology. Here is its management tool: The blue PiraT is an optimised multi-data logger, developed by Telemotive specifically for the automotive industry. With the blue PiraT the communication of bus systems and control units are monitored and relevant data can be recorded very precisely. And here is how the tool is managed: Both applications are created in Java and, as clearly indicated in many ways in the screenshots above, are based on the NetBeans Platform. More details can be found on the Telemotive site.

• Periodic clicking sound from PC speaker

  - by John J. Camilleri

  After an update some months ago, my laptop has begun making a low, repeated clicking sound every few seconds. It is not being generated through the regular sound system, as altering the volume and even muting the sound does not make any difference. My regular audio works fine, by the way, so I am guessing this is some sort of PC speaker, since I cannot hear the click when I listen through regular headphones. Strangely, when I open the sound settings dialog the click magically disappears. I don't need to change any settings; if I simply leave the dialog open in the background then the problem disappears. Any ideas what this could be? I am running regular Ubuntu 12.04, and this is the output from lspci -v | grep -A7 -i "audio": 00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 02) Subsystem: Acer Incorporated [ALI] Device 0349 Flags: bus master, fast devsel, latency 0, IRQ 44 Memory at 54200000 (64-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: snd_hda_intel Kernel modules: snd-hda-intel

• How to handle encryption key conflicts when synchronizing data?

  - by Rafael

  Assume that there is data that gets synchronized between several devices. The data is protected with a symmetric encryption algorithm and a key. The key is stored on each device and encrypted with a password. When a user changes the password only the key gets re-encrypted. Under normal circumstances, when there is a good network connection to other peers, the current key gets synchronized and all data on the new device gets encrypted with the same key. But how to handle situations where a new device doesn’t have a network connection and e.g. creates its own new, but incompatible key? How to keep the usability as high as possible under such circumstances? The application could detect that there is no network and hence refuse to start. That’s very bad usability in my opinion, because the application isn’t functional at all in this case. I don’t consider this a solution. The application could ignore the missing network connection and create a new key. But what to do when the application gains a network connection? There will be several incompatible keys and some parts of the underlying data could only be encrypted with one key and other parts with another key. The situation would get worse if there would be more keys than just two and the application would’ve to ask every time for a password when another object that should get decrypted with another key would be needed. It is very messy and time consuming to try to re-encrypt all data that is encrypted with another key with a main key. What should be the main key at all in this case? The oldest key? The key with the most encrypted objects? What if the key got synchronized but not all objects that got encrypted with this particular key? How should the user know for which particular password the application asks and why it takes probably very long to re-encrypt the data? It’s very hard to describe encryption “issues” to users. So far I didn’t find an acceptable solution, nor some kind of generic strategy. Do you have some hints about a concrete strategy or some books / papers that describe synchronization of symmetrically encrypted data with keys that could cause conflicts?

• Various problems with software raid1 array built with Samsung 840 Pro SSDs

  - by Andy B

  I am bringing to ServerFault a problem that is tormenting me for 6+ months. I have a CentOS 6 (64bit) server with an md software raid-1 array with 2 x Samsung 840 Pro SSDs (512GB). Problems: Serious write speed problems: root [~]# time dd if=arch.tar.gz of=test4 bs=2M oflag=sync 146+1 records in 146+1 records out 307191761 bytes (307 MB) copied, 23.6788 s, 13.0 MB/s real 0m23.680s user 0m0.000s sys 0m0.932s When doing the above (or any other larger copy) the load spikes to unbelievable values (even over 100) going up from ~ 1. When doing the above I've also noticed very weird iostat results: Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s avgrq-sz avgqu-sz await svctm %util sda 0.00 1589.50 0.00 54.00 0.00 13148.00 243.48 0.60 11.17 0.46 2.50 sdb 0.00 1627.50 0.00 16.50 0.00 9524.00 577.21 144.25 1439.33 60.61 100.00 md1 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 md2 0.00 0.00 0.00 1602.00 0.00 12816.00 8.00 0.00 0.00 0.00 0.00 md0 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 And it keeps it this way until it actually writes the file to the device (out from swap/cache/memory). The problem is that the second SSD in the array has svctm and await roughly 100 times larger than the second. For some reason the wear is different between the 2 members of the array root [~]# smartctl --attributes /dev/sda | grep -i wear 177 Wear_Leveling_Count 0x0013 094% 094 000 Pre-fail Always - 180 root [~]# smartctl --attributes /dev/sdb | grep -i wear 177 Wear_Leveling_Count 0x0013 070% 070 000 Pre-fail Always - 1005 The first SSD has a wear of 6% while the second SSD has a wear of 30%!! It's like the second SSD in the array works at least 5 times as hard as the first one as proven by the first iteration of iostat (the averages since reboot): Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s avgrq-sz avgqu-sz await svctm %util sda 10.44 51.06 790.39 125.41 8803.98 1633.11 11.40 0.33 0.37 0.06 5.64 sdb 9.53 58.35 322.37 118.11 4835.59 1633.11 14.69 0.33 0.76 0.29 12.97 md1 0.00 0.00 1.88 1.33 15.07 10.68 8.00 0.00 0.00 0.00 0.00 md2 0.00 0.00 1109.02 173.12 10881.59 1620.39 9.75 0.00 0.00 0.00 0.00 md0 0.00 0.00 0.41 0.01 3.10 0.02 7.42 0.00 0.00 0.00 0.00 What I've tried: I've updated the firmware to DXM05B0Q (following reports of dramatic improvements for 840Ps after this update).

Or maybe sdb is doing also something else besides what sda does. Is there some way to find out if sdb is doing more than what sda does? UPDATE Again, as suggested by Mr. Wagner, I have swapped the 2 SSDs. And as he thought it would happen, the problem moved from sdb to sda. So I guess I'll RMA one of the SSDs. I wonder if the cage might be problematic. What is wrong with this array? Please help!

• Windows 8 client virtualization

  - by John Paul Cook

  Hyper-V is coming to Windows 8, but you must have a processor that supports SLAT. Virtual machines created with Virtual PC aren’t easily transferred to Windows 2008 Hyper-V and vice-versa. With Windows 8, it will be easy to move vhds from Windows 8 on your laptop or desktop to Windows 8 server and back again. To find out if your processor supports SLAT, run coreinfo –v from a command window running as administrator. Download coreinfo from here . My MacBook Pro supports SLAT as this output shows:...(read more)

• Design for an interface implementation that provides additional functionality

  - by Limbo Exile

  There is a design problem that I came upon while implementing an interface: Let's say there is a Device interface that promises to provide functionalities PerformA() and GetB(). This interface will be implemented for multiple models of a device. What happens if one model has an additional functionality CheckC() which doesn't have equivalents in other implementations? I came up with different solutions, none of which seems to comply with interface design guidelines: To add CheckC() method to the interface and leave one of its implementations empty: interface ISomeDevice { void PerformA(); int GetB(); bool CheckC(); } class DeviceModel1 : ISomeDevice { public void PerformA() { // do stuff } public int GetB() { return 1; } public bool CheckC() { bool res; // assign res a value based on some validation return res; } } class DeviceModel2 : ISomeDevice { public void PerformA() { // do stuff } public int GetB() { return 1; } public bool CheckC() { return true; // without checking anything } } This solution seems incorrect as a class implements an interface without truly implementing all the demanded methods. To leave out CheckC() method from the interface and to use explicit cast in order to call it: interface ISomeDevice { void PerformA(); int GetB(); } class DeviceModel1 : ISomeDevice { public void PerformA() { // do stuff } public int GetB() { return 1; } public bool CheckC() { bool res; // assign res a value based on some validation return res; } } class DeviceModel2 : ISomeDevice { public void PerformA() { // do stuff } public int GetB() { return 1; } } class DeviceManager { private ISomeDevice myDevice; public void ManageDevice(bool newDeviceModel) { myDevice = (newDeviceModel) ? new DeviceModel1() : new DeviceModel2(); myDevice.PerformA(); int b = myDevice.GetB(); if (newDeviceModel) { DeviceModel1 newDevice = myDevice as DeviceModel1; bool c = newDevice.CheckC(); } } } This solution seems to make the interface inconsistent. For the device that supports CheckC(): to add the logic of CheckC() into the logic of another method that is present in the interface. This solution is not always possible. So, what is the correct design to be used in such cases? Maybe creating an interface should be abandoned altogether in favor of another design?

• Cursor (touchpad) moves and clicks erratically

  - by James Wood

  Sometimes (usually after two-finger scrolling) the touchpad on my Asus X54C becomes unresponsive and the cursor begins to click and move small distances. Clicking seems to happen more often than moving. Unlike with other similar problems, I've never seen the cursor move to (0, 0). Suspending (closing the lid) and unsuspending doesn't help, and neither does moving to a tty and back or rebooting. I've also tried disabling the touchpad via Fn+F9. That tends to take a long time, but doesn't have any effect. I'm on 13.10 at the moment, but I remember it happening on 13.04 as well. Here's the pointer section of xinput: ? Virtual core pointer id=2 [master pointer (3)] ? ? Virtual core XTEST pointer id=4 [slave pointer (2)] ? ? ETPS/2 Elantech Touchpad id=12 [slave pointer (2)]

• How to control fan speed and temperatures on Asus A8Js laptop running Ubuntu Server?

  - by Azeworai

  Hi, I have tried installing asusfan and lm-sensors but I'm unable to control my fans to cool my laptop down sufficiently. Currently it overheats at about 100 degrees celsius and my sensors output somehow does not have any fan information on it: jackson@OLYMPIA:~$ sensors acpitz-virtual-0 Adapter: Virtual device temp1: +69.0°C (crit = +110.0°C) coretemp-isa-0000 Adapter: ISA adapter Core 0: +66.0°C (high = +100.0°C, crit = +100.0°C) coretemp-isa-0001 Adapter: ISA adapter Core 1: +66.0°C (high = +100.0°C, crit = +100.0°C) I have checked my bios and there isn't any fan settings there. I can consistently overheat just by converting a video via Handbrake. I have ubuntu-desktop installed for a GUI. Is there a way for me to control my fans to start spinning before it reaches a critical temperature and kills itself?

• Real-Time Multi-User Gaming Platform

  - by Victor Engel

  I asked this question at Stack Overflow but was told it's more appropriate here, so I'm posting it again here. I'm considering developing a real-time multi-user game, and I want to gather some information about possibilities before I do some real development. I've thought about how best to ask the question, and for simplicity, the best way that occurred to me was to make an analogy to the field (or playground) game darebase. In the field game of darebase, there are two or more bases. To start, there is one team on each base. The game is a fancy game of tag. When two people meet out in the field, the person who left his base most recently timewise captures the other person. They then return to that person's base. Play continues until everyone is part of the same team. So, analogizing this to an online computer game, let's suppose there are an indefinite number of bases. When a person starts up the game, he has a team that is located at, for example, his current GPS coordinates. It could be a virtual world, but for sake of argument, let's suppose the virtual world corresponds to the player's actual GPS coordinates. The game software then consults the database to see where the closest other base is that is online, and the two teams play their game of virtual tag. Note that the user of the other base could have a different base than the one run by the current user as the closest base to him, in which case, he would be in two simultaneous battles, one with each base. When they go offline, the state of their players is saved on a server somewhere. Game logic calls for the players to have some automaton-logic of some sort, so they can fend for themselves in a limited way using basic rules, until their user goes online again. The user doesn't control the players' movements directly, but issues general directives that influence the players' movement logic. I think this analogy is good enough to frame my question. What sort of platforms are available to develop this sort of game? I've been looking at smartfoxserver, but I'm not convinced yet that it is the best option or even that it will work at all. One possibility, of course, would be to roll out my own web server, but I'd rather not do that if there is an existing service out there already that I could tap into. I will be developing for iOS devices at first. So any suggestions would be greatly appreciated. I think I need to establish the architecture first before proceeding with this project. Note that darbase is not the game I intend to implement, but, upon reflection, that might not be a bad idea either.

A new option, called Capture, allows you to easily select a VM, running or not. The capture will copy the OS disk and data disks and create a new image out of it automatically for you. This means you can now easily clone an entire VM without affecting productivity.  To capture a VM, simply browse to your Virtual Machines in the Microsoft Azure management website, select the VM you want to clone, and click on the Capture button at the bottom. A window will come up asking to name your image. It took less than 1 minute for me to build a clone of my server. And because it is stored as an image, I can easily create a new VM with it. So that’s what I did… And that took about 5 minutes total.  That’s amazing…  To create a new VM from your image, click on the NEW icon (bottom left), select Compute/Virtual Machine/From Gallery, and select My Images from the left menu when selecting an Image. You will find your newly created image. Because this is a clone, you will not be prompted for a new login; the user id/password is the same.

• Integrated ads in phone apps - how to avoid wasting battery?

  - by Jarede

  Considering the PCWorld review that came out in March: Free Android Apps Packed with Ads are Major Battery Drains ...Researchers from Purdue University in collaboration with Microsoft claim that third-party advertising in free smartphone apps can be responsible for as much as 65 percent to 75 percent of an app's energy consumption... Is there a best practice for integrating advert support into mobile applications, so as to not drain user battery too much? ...When you fire up Angry Birds on your Android phone, the researchers found that the core gaming component only consumes about 18 percent of total app energy. The biggest battery suck comes from the software powering third-party ads and analytics accounting for 45 percent of total app energy, according to the study... Has anyone invoked better ways of keeping away from the "3G Tail", as the report puts it? Is it better/possible to download a large set of adverts that are cached for a few hours, and using them to populate your ad space, to avoid constant use of the Wi-Fi/3G radios? Are there any best practices for the inclusion of adverts in mobile apps?

• Adding unit tests to a legacy, plain C project

  - by Groo

  The title says it all. My company is reusing a legacy firmware project for a microcontroller device, written completely in plain C. There are parts which are obviously wrong and need changing, and coming from a C#/TDD background I don't like the idea of randomly refactoring stuff with no tests to assure us that functionality remains unchanged. Also, I've seen that hard to find bugs were introduced in many occasions through slightest changes (which is something which I believe would be fixed if regression testing was used). A lot of care needs to be taken to avoid these mistakes: it's hard to track a bunch of globals around the code. To summarize: How do you add unit tests to existing tightly coupled code before refactoring? What tools do you recommend? (less important, but still nice to know) I am not directly involved in writing this code (my responsibility is an app which will interact with the device in various ways), but it would be bad if good programming principles were left behind if there was a chance they could be used.

• How to control fan speed and temperatures on Asus A8Js laptop?

  - by Azeworai

  Hi, I have tried installing asusfan and lm-sensors but I'm unable to control my fans to cool my laptop down sufficiently. Currently it overheats at about 100 degrees celsius and my sensors output somehow does not have any fan information on it: jackson@OLYMPIA:~$ sensors acpitz-virtual-0 Adapter: Virtual device temp1: +69.0°C (crit = +110.0°C) coretemp-isa-0000 Adapter: ISA adapter Core 0: +66.0°C (high = +100.0°C, crit = +100.0°C) coretemp-isa-0001 Adapter: ISA adapter Core 1: +66.0°C (high = +100.0°C, crit = +100.0°C) I have checked my bios and there isn't any fan settings there. I can consistently overheat just by converting a video via Handbrake. I have ubuntu-desktop installed for a GUI. Is there a way for me to control my fans to start spinning before it reaches a critical temperature and kills itself?
