• Managing a manager who expects too much

  - by dotnetdev

  I am in 3rd line support. We do a lot of bug fixing (although we should be doing other stuff). Quite often, we get systems which are so badly designed and configured (at the server OS level and software level) that they are beyond repair. Yet my manager, even though he was a dev, may swear when I tell him the system is unrepairable (As the person who does our server work gives an opinion that it's FUBAR). However, he still expects it to work without a rebuild. How can I make it work like that when a guy with a million years more experience says the system needs a rebuild?

• Is there a limit on the number of threads that can be spawned simultaneously?

  - by georgesl

  Yesterday I came across this question: How can i call robocopy within a python script to bulk copy multiple folders?, and I though it might be a good exercise for multithreading. I though of spawning as many threads as files needed to be copied, each routine having an exception handling system to prevent the whole copying process from crashing (and log -using mutex on the log file - if there was an error). My question: Is there a limit on the number of thread you can spawn almost simultaneously? If yes, what is the limiting factor? My question is focused on PC desktop, but I welcome any answer on different hardware (embedded systems, calculus clusters, etc.).

• System hangs at glReadPixel call with GL_TEXTURE_2D_ARRAY for texturing

  - by Roshan

  I am calling glReadPixel after glDrawArray call. I am rendering a geometry with 3D texture on it as a target GL_TEXTURE_2D_ARRAY. My systems hangs at glreadpixel call. When i use target as GL_TEXTURE_3D the issue does not occurs and it correctly reads the framebuffer contents. glReadPixels(0, 0, GetViewportWidth(), GetViewportHeight(), GL_RGBA, GL_UNSIGNED_BYTE, (GLvoid *)rendered_pixels); I am using SNORM textures with GL_byte data in glTeximage3D call and I am not calling glPixelStorei, is it because of this? What should be the parameter for pixelstore call?

• Documentation vs tutorials vs video tutorials - which one's better?

  - by Cat

  As a developer/software engineer, what would you say are the most helpful resources when attempting to learn and use a new system? If you had to integrate a new SDK into your codebase/application, which one of the following options would you much rather go with? documentation tutorials video tutorials Same question for learning a new framework (e.g. writing an iOS app, learning Python, integrating the Android SDK, etc.). I'm not referring to becoming an expert, just get to know enough to use a system/language/framework properly. This is a pretty general question, but I think it's very relevant to anyone who's doing engineering work, since learning how to use new systems quickly is a very important skill to have. Thank you!

• Oracle Unveils Oracle Java Embedded Suite 7.0

  - by user12612705

  Today Oracle announced the Oracle Java Embedded Suite 7.0. What is the Java Embedded Suite (JES)? It's a middleware stack designed to be run on embedded devices. It's a suite which includes an application server (Glassfish for Embedded Suite), database (Java DB), and web services (Jersey Web Services Framework). Putting these services on the embedded device gives you the ability to provide a set of services at the device point. It also lets you aggregate data at the device point, which you can later sync with your enterprise systems.

• How to deal with "software end-of-life" situations?

  - by rwong

  When a vendor declares that they no longer intend to provide any support or services to a piece of software (and stated the intent to exit the business - offering no upgrade paths), and stated that customers must pay a nominal fee in order to have the existing data exported, what kind of recourse do programmers/customers have? Things I can think of: Need to purchase spare hardware and set up a spare environment on which the software can continue to operate. Various data export methods which do not require vendor involvement. (For example, screen scraping, printing to image followed by re-scanning, etc) Parallel systems where staff will duplicate the old data into a new system manually or semi-automatically Legal means, in case the vendor is in financial trouble Any other ideas? Assuming that there is no "circumvention" involved (no DRM, no DMCA), is data recovery or reverse engineering legal/acceptable?

• What Application Indicators are available?

  - by user8592

  I installed Ubuntu 11.04 on one of my systems and I am using the Unity interface. Unity is working quite well so far but I really miss panel applets for net speed, cpu temp, and system monitor. These applets are useful for viewing quick info. Unlike 10.10, there is no other way to get this info onto the panel or unity launcher. There are solutions like screenlets and conky but they don't feel appropriate for a clean desktop look. If you know one then please list out any third party indicators with links so that they can be found.

• Ubuntu 12.04 very slow on samsung netbook

  - by vallllll

  I have a samsung netbook n150 1Gb Ram (Intel graphic card), 1,66GHz Intel Atom processor. It was working great with the ubuntu 10.04 netbook edition, really fast boot very eficient but I have updated to 12.04 (the netbook edition doesn't exist anymore) and now the system is so slow: slow boot, sometimes it doesn't even boot properly, strange screen light on and off behaviour, when you click on an icon takes for ever to open the app even the terminal it takes like more than 10s! It seems that this new distro was made for a far more powerful systems than this netbook. I am considering to revert back to 10.04 or choose another linux distro but is there anythhing i can do to fix these problems? Any body else had similar problems. Thanks in advance

• Data architecture for event log metrics?

  - by elliot42

  My service has a large ongoing number of user events, and we would like to do things like "count occurrence of event type T since date D." We are trying to make two basic decisions: What to store? Storing every event vs. only storing aggregates (Event log style) log every event and count them later, vs. (Time-series style) store a single aggregated "count of event E for date D" for every day Where to store the data In a relational database (particularly MySQL) In a non-relational (NoSQL) database In flat log files (collected centrally over the network via syslog-ng) What is standard practice / where can I read more about comparing the different types of systems? Additional details: The total event stream is large, potentially hundreds of thousands of entries per day But our current need is only to count certain types of events within it We don't necessarily need real-time access to the raw data or aggregation results IMHO, "log all events to files, crawl them at a later time to filter and aggregate the stream" is a pretty standard UNIX Way, but my Rails-y compatriots seem to think that nothing is real unless it's in MySQL.

• Itty bitty ITTIA DB for Java Embedded Device Development

  - by hinkmond

  Here's a nice 3rd party itty-bitty database, called ITTIA DB, for Java Embedded and Mobile development See: ITTIA DB for Java Embedded Here's a quote: Java applications on mobile devices and other embedded systems can now leverage the robust shared access and data distribution features of ITTIA DB SQL with a new JDBC (Java Database Connectivity) driver released this week. This driver provides significant value for Java developers targeting embedded platforms such as QNX and Linux. Plus, it can exchange data with an Oracle back-end database. That's good if that's what you have on the back-end. Hinkmond

• Help with Dial Up

  - by iSeth

  I am trying to set up a computer for my friend that has dial up. The problem is nothing I try can detect the modem. GnomePPP can't find it and I can't figure Kppp out. I've been looking all over the net on my ethernet trying to find an answer but I keep getting routed back here. I have also tried using scanModem and it finds something like Conexant Systems, Inc. HCF 56k Data/Fax/Voice Modem but the rest of it is really confusing. I've also tried this but I'm not very terminal savvy and it didn't work. It seems like I have to compile a driver but I don't know which one or how to do it. I have also tried multiple modems. Any help would be appreciated. Thanks EDIT: scanModem thinks the modem is disabled on startup. EDIT: I reinstalled Ubuntu but the problem persists.

• How do I output my audio input?

  - by VarLogRant

  A few iterations ago, I think this was Jaunty but could've been before, I would plug a 1/8" audio cable from the line-out of a Windows netbook to the line-in of my Ubuntu machine, so I would have all the sound from both machines without having to plug both into a mixer which I don't have. I didn't do this much, as I was pretty-much happy with Banshee at the time. But with Karmic, and still with Lucid, I can only get the output if I'm recording with Audacity. Which I'm not going to do from my web-development and systems programming workstation. I can tell by plugging in headphones that my netbook has audio out working. I can see Sound Preferences that the Ubuntu machine is receiving them. I just want the old behavior back. Help?

• lighter-weight (semantic) scuttle

  - by hroptatyr

  Before patching scuttle or semanticscuttle I thought I'd ask if anyone knows of a lighter-weight/faster system to tag bookmarks and vote on them? LAMP is fine. Ideally, I should be allowed to interfere with the database directly. My actual problem is I want to administer roughly 80m bookmarks, tag them, vote on them (it's just 10 users accessing the system), but here's the thing: All of those bookmarks will change their descriptions (and title lines) at least once a day. Both systems support the del.icio.us API but my LAMP stack is unable to cope with the load.

• Are "skip deltas" unique to svn?

  - by echinodermata

  The good folks who created the SVN version control system use a structure they refer to as "skip deltas" to store the revision history of files internally. A revision is stored as a delta against an earlier revision. However, revision N is not necessarily stored as a delta against revision N-1, like this: 0 <- 1 <- 2 <- 3 <- 4 <- 5 <- 6 <- 7 <- 8 <- 9 Instead, revision N is stored as a delta against N-f(N), where f(N) is the greatest power of two that divides N: 0 <- 1 2 <- 3 4 <- 5 6 <- 7 0 <------ 2 4 <------ 6 0 <---------------- 4 0 <------------------------------------ 8 <- 9 (Superficially it looks like a skip list but really it's not that similar - for instance, skip deltas are not interested in supporting insertion in the middle of the list.) You can read more about it here. My question is: Do other systems use skip deltas? Were skip deltas known/used/published before SVN, or did the creators of SVN invent it themselves?
