• getting started as a web developer [closed]

  - by kmote

  I have over 10 years of programming experience building (Windows-based) desktop applications and utilities (VC++, C#, Python). My goal over the next year is to start transitioning to web application development. I want to teach myself the fundamental tools and technologies that would be considered essential for building professional, online, interactive, visually-stunning, data-driven web apps -- the kind described in Google's recently released "Field Guide: Building Great Web Applications". So my question is, what are the primary, most commonly-used technologies that seasoned professionals will need in their tool belt in the coming years? My plan was to start coming up to speed in Javascript, HTML5, & CSS, and then to do a deep dive into ASP.NET and Ajax, along with SQL DBs. (I was surprised to not be able to find a single book at Amazon with a broad, general scope like this, which caused me to start second-guessing this approach.) So, seasoned professionals: am I on the right track? Are there some glaring omissions in my list? Or some unnecessary inclusions? I would welcome any book suggestions along these lines as well.

• Ubuntu running like mud, system hangs and looks like its running at 3FPS

  - by user240803

  the system specks: AMD XP 3200+ 1GB DDR 333 RAM 160 GB HD IDE NVIDIA FX 5500 AGP Video Card Compaq Presario sr1230nx the system takes forever to boot and when it does it runs like total mud, reminds me of an overloaded system that has too many windows open or something... fresh install tried soo many thing like new memory (it had 512 stick) a new video card (onboard 8mb sis sounded like the problem, but wasn't... has gotten a little faster now but not by much) tried to disable all the things on the motherboard that could be, with no help... this machine runs windows XP, 7, and 8 JUST FINE!!! I mean for a single core CPU WIN8 runs AWESOME!!! BUT I already have a Gaming Desktop that has Windows 8 pro I want a Linux machine to get some time in and learn a few things... I want Ubuntu because of the Software center so I can install things I want until I am familiar with the command line.. I've worked on Computers since I was 12 I remember some of the DOS commands but I guess these are a little different... anyway any ideas? Ive also tried both drivers for the NVIDA card and that didn't help either... its not the card since it did this with both the NVIDA card and the SIS onboard... it also does this on live mode with the USB so I don't think its the HardDrive... I'm running out of options of hardware to try... I know this version of Linux works cuz Ive booted it on other machines and it ran great... what is with this Compaq? here is a vid of exactly what its doing... let me know if you need anything else I am right by the comptuer tonight so ask anything... http://youtu.be/-P-XNo81098

• M-Audio Delta starts up at wrong sample rate

  - by steevc

  When the PC starts my M-Audio Delta 66 is using 48000kHz sampling rate when it is set for 44100 in Envy24. This causes audio to play slower than it should. This is in Kubuntu 14.04 on my new PC using an AMD A8 6500 with 8GB. When I first installed it seemed okay, but at some point it went wrong and has been doing this consistently since then. Kernel is 3.13.0-24-generic #47-Ubuntu SMP Fri May 2 23:31:42 UTC 2014 i686 athlon i686 GNU/Linux steve@slarti:~$ cat /proc/asound/card2/pcm0p/sub0/hw_params access: MMAP_INTERLEAVED format: S32_LE subformat: STD channels: 10 rate: 48000 (48000/1) period_size: 441 buffer_size: 3528 I can get it to switch to 44100 if I disable/enable the Delta in Pulseaudio volume control, but I have to do this every day and the sound still seems distorted. I can't see any issues in any of the config or log files I can find. If I boot the PC with a Mint Live USB it starts at 44100 and sound fine. Originally reported on Youtube is playing at the wrong speed - maybe soundcard related, but I'll close that and have this more relevant question instead.

• New SPC2 benchmark- The 7420 KILLS it !!!

  - by user12620172

  This is pretty sweet. The new SPC2 benchmark came out last week, and the 7420 not only came in 2nd of ALL speed scores, but came in #1 for price per MBPS. Check out this table. The 7420 score of 10,704 makes it really fast, but that's not the best part. The price one would have to pay in order to beat it is ridiculous. You can go see for yourself at http://www.storageperformance.org/results/benchmark_results_spc2The only system on the whole page that beats it was over twice the price per MBPS. Very sweet for Oracle. So let's see, the 7420 is the fastest per $. The 7420 is the cheapest per MBPS. The 7420 has incredible, built-in features, management services, analytics, and protocols. It's extremely stable and as a cluster has no single point of failure. It won the Storage Magazine award for best NAS system this year. So how long will it be before it's the number 1 NAS system in the market? What are the biggest hurdles still stopping the widespread adoption of the ZFSSA? From what I see, it's three things: 1. Administrator's comfort level with older legacy systems. 2. Politics 3. Past issues with Oracle Support.   I see all of these issues crop up regularly. Number 1 just takes time and education. Number 3 takes time with our new, better, and growing support team. many of them came from Oracle and there were growing pains when they went from a straight software-model to having to also support hardware. Number 2 is tricky, but it's the job of the sales teams to break through the internal politics and help their clients see the value in oracle hardware systems. Benchmarks like this will help.

• Disaster Recovery Example

  Previously, I use to work for a small internet company that sells dental plans online. Our primary focus concerning disaster prevention and recovery is on our corporate website and private intranet site. We had a multiphase disaster recovery plan that includes data redundancy, load balancing, and off-site monitoring. Data redundancy is a key aspect of our disaster recovery plan. The first phase of this is to replicate our data to multiple database servers and schedule daily backups of the databases that are stored off site. The next phase is the file replication of data amongst our web servers that are also backed up daily by our collocation. In addition to the files located on the server, files are also stored locally on development machines, and again backed up using version control software. Load balancing is another key aspect of our disaster recovery plan. Load balancing offers many benefits for our system, better performance, load distribution and increased availability. With our servers behind a load balancer our system has the ability to accept multiple requests simultaneously because the load is split between multiple servers. Plus if one server is slow or experiencing a failure the traffic is diverted amongst the other servers connected to the load balancer allowing the server to get back online. The final key to our disaster recovery plan is off-site monitoring that notifies all IT staff of any outages or errors on the main website encountered by the monitor. Messages are sent by email, voicemail, and SMS. According to Disasterrecovery.org, disaster recovery planning is the way companies successfully manage crises with minimal cost and effort and maximum speed compared to others that are forced to make decision out of desperation when disasters occur. In addition Sun Guard stated in 2009 that the first step in disaster recovery planning is to analyze company risks and factor in fixed costs for things like hardware, software, staffing and utilities, as well as indirect costs, such as floor space, power protection, physical and information security, and management. Also availability requirements need to be determined per application and system as well as the strategies for recovery.

• Hosting and scaling of a facebook application on cloud?

  - by DhruvPathak

  We would be building a facebook application in django(Python), but still not sure of where to host it economically,and with a good provision to scale in case the app gets viral. Some details about the app: i) Would be HTML based like a website,using django as a framework. ii) 100K is the number of expected pageviews in a day,if the app is viral. iii) The users will not generate any media content,only some database data will be generated by them. It would be great if someone with more experience can guide on following points: A) Hosting on google app engine or Amazon EC2 or some other cloud like RackSpace : Preferable points found in AppEngine were ease of deployment,cost effectiveness and easy scaling. For EC2: Full hold of the virtual machine,Amazon NoSQL and RDMBS database services in case we decide to use them. B) Does backend technology affect monthly cost ? eg. would CPU and memory usage difference of Django over , for example , PHP framework like CodeIgnitor really make remarkable difference in running costs. ( Here is the article that triggered this thought process : http://journal.dedasys.com/2010/01/12/rough-estimates-of-the-dollar-cost-of-scaling-web-platforms-part-i#comments) C) Does something like Heroku , which provides additional services over Amazon EC2, prove to be better than raw cloud management ? It is not that we are trying for premature scaling, we just want to have a good start so that we are ready to handle unpredicted growth and scale.

• Improving the efficiency of my bloom/glow shader

  - by user1157885

  I'm making a neon style game where everything is glowing but the glow I have is kinda small and I want to know if there's an efficient way to increase the size of it other than increasing the pixel sample iterations. Right now I have something like this: float4 glowColor = tex2D(glowSampler, uvPixel); //Makes the inital lines brighter/closer to white if (glowColor.r != 0 || glowColor.g != 0 || glowColor.b != 0) { glowColor += 0.5; } //Loops over the weights and offsets and samples from the pixels based on those numbers for (int i = 0; i < 20; i++) { glowColor += tex2D(glowSampler, uvPixel + glowOffsets[i] + 0.0018) * glowWeights[i]; } finalColor += glowColor; for the offsets it moves up, down, left and right (5 times each so it loops over 20 times) and the weights just lower the glow amount the further away it gets. The method I was using before to increase it was to increase the number of iterations from 20 to 40 and to increase the size of the offset/weight array but my computer started to have FPS drops when I was doing this so I was wondering how can I make the glow bigger/more vibrant without making it so CPU/Gcard intensive?

• The balance between client and server functionality

  - by Eugen Martynov

  I want to bring the discussion that started in our teams and get your opinion about it. Assume we have an user account which could have different credentials for authentication and associated email to recover. An user has possibility to do signup with an email or use his social profile to complete signup process. As an Rest API from the backend to client looks like: Create account Authorise Update user data Link social account Register email Verify email In addition our BE is distributed and divided between several services/servers/clusters. So different calls are related to different end points. In case of the social sign up some of steps should be skipped or simplified. For example, with Facebook signup we could already skip email registration and verification step (we ask email permission form user), linking the social account and pre-fill user displayed name. So we proposed to have another end point which will hide/combine different calls on BE and return whole process result to the clients. The pros for this approach: No more duplication of functionality between clients Speed up the networking and user experience The cons for this approach: Additional work for backend Probably most complex scenarios in future updates I would like to get your opinion or experience with this situation. Especially if you already experienced point #2 from against reasons.

• Are there any significant advantages to using a native language for mobile app development?

  - by Karl Daniel

  Forgive me if this question has already been answered but I couldn't quite find the answer I was looking for. What I wanted to know was, is there any significant advantage to using a native language when developing and deploying apps to a mobile environment? The reason I ask is for a long while now I've been using Objective-C, Apple's native language for iOS, to build my apps. However I've been wondering whether or not there is any real benefit to doing this, over using a non-native language like JavaScript and then deploying it through a service like 'Phone Gap'? I do stress 'significant' advantages as native languages are always more likely to have the upper hand when it comes to speed and access to the latest APIs. However in general I don't see using a non-native language or a service like 'Phone Gap' causing and major slow down to my apps or restricting my development. Additionally having the ability to deploy to multiple services is also very handy indeed. This is why I put the question, are there any significant advantages to using a native language for mobile app development?

• Hash Algorithm Randomness Visualization

  - by clstroud

  I'm curious if anyone here has any idea how the images were generated as shown in this response: Which hashing algorithm is best for uniqueness and speed? Ian posted a very well-received response but I can't seem to understand how he went about making the images. I hate to make a new question dedicated to this, but I can't find any means to ask him more directly. On the other hand, perhaps someone has an alternative perspective. The best I can personally come up with would be to have it almost like a bar graph, which would illustrate how evenly the buckets of the hash table are being generated. I have a working Cocoa program that does this, but it can't generate anything like what he showed there. So the question is two fold I suppose: A) How does one truly interpret the data he shows? Is it more than "less whitespace = better"? B) How does one generate such an image based on some set of inputs, a hash, and an index? Perhaps I'm misunderstanding entirely, but I really would like to know more about this particular visualization technique. Or maybe I'm mis-applying this to hash tables rather than just hashes in general, but in that case I don't know how it would be "bounded" for the image.

• Copy to USB memory stick really slow?

  - by Eloff

  When I copy files to the USB device, it takes much longer than in windows (same usb device, same port) it's faster than USB 1.0 speeds (1MB/s) but much slower than USB 2.0 speeds (12MB/s). To copy 1.8GB takes me over 10 minutes (it should be < 3 min.) I have two identical SanDisk Cruzer 8GB sticks, and I have the same problem with both. I have a super talent 32GB USB SSD in the neighboring port and it works at expected speeds. The problem I seem to see in the GUI is that the progress bar goes to 90% almost instantly, completes to 100% a little slower and then hangs there for 10 minutes. Interrupting the copy at this point seems to result in corruption at the tail end of the file. If I wait for it to complete the copy is successful. Any ideas? dmesg output below: [64059.432309] usb 2-1.2: new high-speed USB device number 5 using ehci_hcd [64059.526419] scsi8 : usb-storage 2-1.2:1.0 [64060.529071] scsi 8:0:0:0: Direct-Access SanDisk Cruzer 1.14 PQ: 0 ANSI: 2 [64060.530834] sd 8:0:0:0: Attached scsi generic sg4 type 0 [64060.531925] sd 8:0:0:0: [sdd] 15633408 512-byte logical blocks: (8.00 GB/7.45 GiB) [64060.533419] sd 8:0:0:0: [sdd] Write Protect is off [64060.533428] sd 8:0:0:0: [sdd] Mode Sense: 03 00 00 00 [64060.534319] sd 8:0:0:0: [sdd] No Caching mode page present [64060.534327] sd 8:0:0:0: [sdd] Assuming drive cache: write through [64060.537988] sd 8:0:0:0: [sdd] No Caching mode page present [64060.537995] sd 8:0:0:0: [sdd] Assuming drive cache: write through [64060.541290] sdd: sdd1 [64060.544617] sd 8:0:0:0: [sdd] No Caching mode page present [64060.544619] sd 8:0:0:0: [sdd] Assuming drive cache: write through [64060.544621] sd 8:0:0:0: [sdd] Attached SCSI removable disk

• How do I left-click a Java Application on a WeTab running Ubuntu 12.10? (workaround defect in Onboard)

  - by Kat Amsterdam

  I installed Ubuntu 12.10 on my weTab. Everything works perfectly (albeit slowly) and I can touch and use every application execpt ones written in Java. When I start any Java Application the touchscreen does not recognize the left click. I believe it's a problem in OnBoard (the onscreen keyboard) because when I touch the mouse icon on the OnBoard and then the Java Application the left click works. This is very cumbersome for every click to first hit OnBoard mouse icon and then button in the Java app I would like to click. It defeats the purpose of a touchscreen. The Java Application is definitly touchable as it's running on 10 other machines with Elo Touchscreen. How do I get Ubuntu to recognize the left click in a java application automatically when I touch the screen? Or a way to dignose this so I can make a clear bug report? This happens in all the desktop environments (Gnome/Unity, XFCE4 and LXDE) I tried with openjdk-6-* and openjdk-7-* Stats: WeTab 32GB 3G 2GB RAM Intel(R) Atom(TM) CPU N450 @ 1.66GHz - 64-bit Ubuntu 12.10 - 64 bit Unity Desktop environment Xubuntu Desktop environment Lubuntu Desktop environment The real touchscreen driver from EETI (eGalaxy) (also didn't work with the Ubuntu standard touchscreen driver)

• File browsing on Nautilus extremely slow after upgrade to 12.04

  - by Tobelli

  One month ago I updated (no fresh install) to 12.04. Since then nautilus got extremely slow. When I open a folder that contains many subfolders I sometimes have to wait 4 seconds until everything is displayed. This has never been like that before, in previous versions I could always browse between my files extremely fast. I looked in "additional drivers" and changed from Nvidia current-version-update to the recommended drivers. This drastically increased the performance and speed of file browsing, unfortunately just for a couple of days. Now I am stuck again with the very slow Nautilus. I also tried to install the latest nvidia driver like it was suggested here: http://www.techlw.com/2012/03/install-nvidia-drivers-on-ubuntu-1204.html Did not work at all. Also when using the dash to try to find files it does not respond properly: does not find files or loads for ages until the file is displayed. I am working on an Acer Notebook with Intel® Core™ i5 CPU M 430 @ 2.27GHz × 4 6GB RAM GeForce GT 320M/PCIe/SSE2 64 Bit Ubuntu 12.04

• How to uninstall Ubuntu 12.04 LTS dual booting with Windows 7?

  - by user103799

  I need to uninstall Ubuntu 12.04 LTS from my laptop. It's currently dual booting with windows 7. I've searched and found some ways to do this, but all use some kind of a CD to complete the deletion. I have neither the Ubuntu Live CD nor Windows Install CD/Recovery CD. This laptop did not come with one, and I unfortunately have no available storage device to make a recovery CD. Is there a way to completely uninstall Ubuntu 12.04 LTS dual booting without using any hardware? If there's no way, then how to uninstall using the least hardware possible? Or easy to find hardware? I've nothing against Ubuntu. I installed this as a backup/alternative to error-prone Windows 7. However, after a hardware upgrade, including extra RAMs and a new, better CPU, Windows 7 runs smoothly again. Now I'm running low on hard drive space and need the 40 gig or so of space I partitioned for Ubuntu back. Any help is appreciated, and thanks in advance!

• Should I avoid or embrace asking questions of other developers on the job?

  - by T.K.

  As a CS undergraduate, the people around me are either learning or are paid to teach me, but as a software developer, the people around me have tasks of their own. They aren't paid to teach me, and conversely, I am paid to contribute. When I first started working as a software developer co-op, I was introduced to a huge code base written in a language I had never used before. I had plenty of questions, but didn't want to bother my co-workers with all of them - it wasted their time and hurt my pride. Instead, I spent a lot of time bouncing between IDE and browser, trying to make sense of what had already been written and differentiate between expected behavior and symptoms of bugs. I'd ask my co-workers when I felt that the root of my lack of understanding was an in-house concept that I wouldn't find on the internet, but aside from that, I tried to confine my questions to lunch hours. Naturally, there were occasions where I wasted time trying to understand something in code on the internet that had, at its heart, an in-house concept, but overall, I felt I was productive enough during my first semester, contributing about as much as one could expect and gaining a pretty decent understanding of large parts of the product. I was wondering what senior developers felt about that mindset. Should new developers ask more questions to get to speed faster, or should they do their own research for themselves? I see benefits to both mindsets, and anticipate a large variety of responses, but I figure new developers might appreciate your answers without thinking to ask this question.

• Globacom and mCentric Deploy BDA and NoSQL Database to analyze network traffic 40x faster

  - by Jean-Pierre Dijcks

  In a fast evolving market, speed is of the essence. mCentric and Globacom leveraged Big Data Appliance, Oracle NoSQL Database to save over 35,000 Call-Processing minutes daily and analyze network traffic 40x faster.  Here are some highlights from the profile: Why Oracle “Oracle Big Data Appliance works well for very large amounts of structured and unstructured data. It is the most agile events-storage system for our collect-it-now and analyze-it-later set of business requirements. Moreover, choosing a prebuilt solution drastically reduced implementation time. We got the big data benefits without needing to assemble and tune a custom-built system, and without the hidden costs required to maintain a large number of servers in our data center. A single support license covers both the hardware and the integrated software, and we have one central point of contact for support,” said Sanjib Roy, CTO, Globacom. Implementation Process It took only five days for Oracle partner mCentric to deploy Oracle Big Data Appliance, perform the software install and configuration, certification, and resiliency testing. The entire process—from site planning to phase-I, go-live—was executed in just over ten weeks, well ahead of the four months allocated to complete the project. Oracle partner mCentric leveraged Oracle Advanced Customer Support Services’ implementation methodology to ensure configurations are tailored for peak performance, all patches are applied, and software and communications are consistently tested using proven methodologies and best practices.

• game play strategy in an arena

  - by joulesm

  I am writing a player's behavior for an arena game, and I'm wondering if you can offer some strategies. I'm writing it in Python, but I'm just interested in the high level game play. Here are the game aspects: Arena is a circle of a given size. The arena size shrinks every round to help break ties. Players are much smaller circles, can be on teams of 1 or 2 players. Players attack by colliding with other players, and based on the physics of the collision (speed of both players, angle), one could force another player out of the arena. Once a player is out of the arena, they are out of the game (for that round). The goal is to be the only team with players left in the arena. All other players have been pushed (through collisions or mistakes) out of the arena. It is possible for there to be no winner if the last two players exit the arena at the same time. Once the player has been programmed, the game just runs. There is no human intervention in the game. I'm thinking it's easiest to implement a few simple programmatic rules for my player to follow. For example, stay close to center of the arena, attack opponents from the inner side of the arena, etc. Are there any good simple game strategies? Would adding a random aspect to the game help? For example, to avoid predictability by the other team or something. Thanks in advance.

• Dual Booting Windows 7 and Ubuntu 12.04. Partition Sizes?

  - by John F.

  I'm about to reinstall Windows, so I thought that I'd try Ubuntu out on a partition just for fun. My question is, how large should my partitions be for each of them? I know this various depending on what you use, so i'll give you a general idea of what I have, and what I have in mind. I'm currently running: Windows 7 Professional (64bit) RAM: 4GB CPU: 2.5Ghz Quad Core processor HDD: 500GB GPU: 1GB Nvidia GeForce I have around 130GB in Steam games, and some heavier applications like Photoshop CS6, Sony Vegas Pro 11. But other Applications I use are: Chrome Skype Dxtory Fraps OpenOffice BitTorrent and other assorted smaller programs. So, I was thinking that I would give my Windows partition about 150-200GB, my Ubuntu Partition around 20GB, and the rest to shared storage. I'm not really sure if I'd need more or less on Ubuntu, because I've never used it and I'm not really sure what kind of apps i'd be using over there. This would also be a clean install, so I'd be wiping my HDD, creating the Partitions in GParted, then installing Windows with Ubuntu following that. Any critique you could give me? Maybe explanations to what the /root, /boot and /home partitions I hear are about? Thanks in advanced if you actually read this lengthy thing! Any help is appreciated. (x

• When does a programmer know when a new job is not right?

  - by Mysterion

  I believe that the interview process is a selling of both parties - what can the employee offer the employer and vice versa. Assuming an individual has been careful in selecting their new employer (via thorough questioning in the interview process), however when they arrive at the job they find the employer has not been honest about certain aspects of the job. Examples of this dishonesty could include: The employee making it clear that technical excellence is an important factor, which is promised by the employer, but is not fully delivered or a good technical structure does not exist. The employee states they want to work on well architected and short (lets say less than 1 yr) long projects, yet when they start they find they are placed on a poorly architected older project. The employee being told of a pair programming environment to get him up to speed on the project, but being left to his own devices/questioning on arrival. The employee is promised a culture that encourages innovation and technical excellence but finds that this is not the case (eg. using technology for knowledge retention is laughed at). I know that a lot of famous developers feel that you make the place you work at. Is it realistic for a new employee with limited experience in the industry (say less than 5 years) to be able to join the company and change attitudes or even challenge the employer on the perceived dishonesty? Should they stay in this job or cut their losses?

• Series On Embedded Development (Part 3) - Runtime Optionality

  - by Darryl Mocek

  What is runtime optionality? Runtime optionality means writing and packaging your code in such a way that all of the features are available at runtime, but aren't loaded and used if the feature isn't used. The code is separate, and you can even remove the code to save persistent storage if you know the feature will not be used. In native programming terms, it's splitting your application into separate shared libraries so you only have to load what you're using, which means it only impacts volatile memory when enabled at runtime. All the functionality is there, but if it's not used at runtime, it's not loaded. A good example of this in Java is JVMTI, Java's Virtual Machine Tool Interface. On smaller, embedded platforms, these libraries may not be there. If the libraries are not there, there's no effect on the runtime as long as you don't try to use the JVMTI features. There is a trade-off between size/performance and flexibility here. Putting code in separate libraries means loading that code will take longer and it will typically take up more persistent space. However, if the code is rarely used, you can save volatile memory by including it in a separate library. You can also use this method in Java by putting rarely-used code into one or more separate JAR's. Loading a JAR and parsing it takes CPU cycles and volatile memory. Putting all of your application's code into a single JAR means more processing for that JAR. Consider putting rarely-used code in a separate library/JAR.

• On Screen Coin Animation

  - by Siddharth

  am working with side scrolling skater game. I want to perform coin animation such that as player collect coin it moves upside and attach with currency sprite. My main character and coin present in game scene and currency sprite present in HUD layer. This situation creates problem for me. Directly I can not apply modifier to coin because it is side scrolling game so based on main character speed it reaches at different position. That I have checked. So that I have to generate other coin at same position at game layer coin has, in HUD layer and move upward to it. But I didn't able to get its y position correct though I can able to get x position correctly. Many time main character goes downward so it get minus value many time. I also tried following code float[] position = GameHUD.this .convertSceneCoordinatesToLocalCoordinates(GameManager .getInstance().getCoinX(), GameManager.getInstance() .getCoinY()); But I am getting same coordinate as I provide. No difference in that so please some one provide me guidance in that. Because I am near to complete my game. EDIT: Here game layer and hud layer is totally different. Actual coin present in game layer which player has to collect and at same position I want to generate another coin in hud layer to perform some animation. It is recommended to generate coin in hud layer because through that only I can able to complete my target.

• What to do when 'dpkg --configure -a' fails with too many errors?

  - by rudivonstaden

  During an upgrade from lucid (10.04) to precise (12.04), the X session froze, and I have been trying to recover the upgrade to get a stable system. I have performed the following steps: Used ssh to log in to the stalled system over the network. Checked the contents of the /var/log/dist-upgrade directory. There was no activity on main.log, apt.log or term.log. top showed that process 'precise' was using about 3% CPU, but I could find no evidence that the upgrade process was still doing anything. 'dpkg' did not show up in top, but it came up with pgrep dpkg | xargs ps Killed the 'dpkg' and 'precise' processes Tried to recover the upgrade by running sudo fuser -vki /var/lib/dpkg/lock;sudo dpkg --configure -a. This was partially successful (some packages were configured), but failed with the message Processing was halted because there were too many errors. I ran the same command a few times, and each time some packages were configured but others failed. Tried running sudo apt-get -f install. It fails with similar errors to dpkg. The current situation is that dpkg --configure -a and sudo apt-get -f install fails with two kinds of error: Dependency issues, e.g.: dpkg: dependency problems prevent configuration of cifs-utils: cifs-utils depends on samba-common; however: Package samba-common is not configured yet. dpkg: error processing cifs-utils (--configure): dependency problems - leaving unconfigured Resource conflict, e.g.: debconf: DbDriver "config": /var/cache/debconf/config.dat is locked by another process: Resource temporarily unavailable Additionally, it seems there's reference to potential boot problems, so I'm not keen to reboot without fixing the install first: dpkg: too many errors, stopping Processing triggers for initramfs-tools ... update-initramfs: Generating /boot/initrd.img-3.2.0-25-generic cryptsetup: WARNING: failed to detect canonical device of /dev/sda1 cryptsetup: WARNING: could not determine root device from /etc/fstab So my question is, how to get a working install when dpkg --configure -a fails?
