• what is the purpose of arrows?

  - by Simon

  I am learning functionnal programming with Haskell, and I try to grab concepts by first understanding why do I need them. I would like to know the goal of arrows in functional programming languages. What problem do they solve? I checked http://en.wikibooks.org/wiki/Haskell/Understanding_arrows and http://www.cse.chalmers.se/~rjmh/afp-arrows.pdf. All I understand is that they are used to describe graphs for computations, and that they allow easier point free style coding. The article assume that point free style is generally easier to understand and to write. This seems quite subjective to me. In another article (http://en.wikibooks.org/wiki/Haskell/StephensArrowTutorial#Hangman:_Main_program), a hangman game is implemented, but I cannot see how arrows makes this implementation natural. I could find a lot of papers describing the concept, but nothing about the motivation. What I am missing?

• How can I open binary image files? (.img)

  - by Simon Cahill

  I'm a Windows/Mac/Ubuntu and Androoid user, so I know what I'm talking about, when I say: How do I open binary image files? (.img) They just won't open, on any OS... I'm an Android dev... I'm currently working on a ROM, (I also program, using Windows) but I need to extract files, from .img files. I've converted them to .ext4.img but they just aren't recognized by Linux (Definitly not by Android), by Mac OS or Windows. In other words, I can't open, extract or mount them. Can anyone help me? I'm kinda confused...

• Use of list-unsubscribe to improve inbox delivery

  - by Jeffrey Simon

  To overcome email being classified as spam by Gmail, Google recommends a number of steps, which we have implemented (namely SPF, DKIM, and Precedence: bulk). One additional measure they recommend at https://support.google.com/mail/bin/answer.py?hl=en&answer=81126#authentication reads as follows: Because Gmail can help users automatically unsubscribe from your email, we strongly recommend the following: Provide a 'List-Unsubscribe' header which points to an email address where the user can unsubscribe easily from future mailings (Note: This is not a substitute method for unsubscribing). Documentation for List-Unsubscribe is found at http://www.list-unsubscribe.com/. From this documentation I expect a button to be provided by a supported mail client. I have tested the 'List-Unsubscribe' header and it does not appear to provide the button. I have tested in both Gmail and OS X Mail. I tested with an http address and with both an email address and an http address. The format of the header is as follows: List-Unsubscribe: <mailto:[email protected]>, <http://domain.com/member/unsubscribe/[email protected]?id=12345N> No button appears in any test. My questions: How widely is List-Unsubscribe supported? Should a button be appearing somewhere, or does something else have to be present? I have seen a comment that even if the button is not present, services like Gmail, Yahoo, Hotmail/Windows Live would give higher regard to email having the header. Thus it might be worthwhile for this aspect alone. Please note that our standard email footer already contacts instructions and a link to allow unsubscribing from our email. Finally, is it worth while to implement this header? (That is, any downsides?)

• File Permissions

  - by Simon Bateman

  Some years/versions ago I found a script that took the Directory group/permissions of the current folder for NEW files Sub-Folders Currently when I import Photographs into 12.04 using Shotwell, I have to use terminal to issue: chgrp photography *.JPG. This enables other ubuntu members of 'photography' group to add these files to their version of Shotwell. I find modifying the Folder Properties/Permissions will NOT set the Group on 'Apply Permissions to Enclosed Files'

• Best Resources for learning SQL? [closed]

  - by Simon

  Possible Duplicate: Good Books and videos for absolute beginner to SQL I have landed a role as a product engineer for a web based product. A big part of the product is allowing its users the ability to create queries with SQL to pull in business information from their back end databases. I know the very basics of SQL and need to spend some time getting a better grasp on SQL. I have the tutorial from w3schools on my ToDo list, but was hoping to get some answers that point me to good resources for learning SQL. I have no preference - I can buy a book (SQL For Dummies?), or online resources, online videos, audio, etc.

• Developing Schema Compare for Oracle (Part 4): Script Configuration

  - by Simon Cooper

  If you've had a chance to play around with the Schema Compare for Oracle beta, you may have come across this screen in the synchronization wizard: This screen is one of the few screens that, along with the project configuration form, doesn't come from SQL Compare. This screen was designed to solve a couple of issues that, although aren't specific to Oracle, are much more of a problem than on SQL Server: Datatype conversions and NOT NULL columns. 1. Datatype conversions SQL Server is generally quite forgiving when it comes to datatype conversions using ALTER TABLE. For example, you can convert from a VARCHAR to INT using ALTER TABLE as long as all the character values are parsable as integers. Oracle, on the other hand, only allows ALTER TABLE conversions that don't change the internal data format. Essentially, every change that requires an actual datatype conversion has to be done using a rebuild with a conversion function. That's OK, as we can simply hard-code the various conversion functions for the valid datatype conversions and insert those into the rebuild SELECT list. However, as there always is with Oracle, there's a catch. Have a look at the NUMTODSINTERVAL function. As well as specifying the value (or column) to convert, you have to specify an interval_unit, which tells oracle how to interpret the input number. We can't hardcode a default for this parameter, as it is entirely dependent on the user's data context! So, in order to convert NUMBER to INTERVAL DAY TO SECOND/INTERVAL YEAR TO MONTH, we need to have feedback from the user as to what to put in this parameter while we're generating the sync script - this requires a new step in the engine action/script generation to insert these values into the script, as well as new UI to allow the user to specify these values in a sensible fashion. In implementing the engine and UI infrastructure to allow this it made much more sense to implement it for any rebuild datatype conversion, not just NUMBER to INTERVALs. For conversions which we can do, we pre-fill the 'value' box with the appropriate function from the documentation. The user can also type in arbitary SQL expressions, which allows the user to specify optional format parameters for the relevant conversion functions, or indeed call their own functions to convert between values that don't have a built-in conversion defined. As the value gets inserted as-is into the rebuild SELECT list, any expression that is valid in that context can be specified as the conversion value. 2. NOT NULL columns Another problem that is solved by the new step in the sync wizard is adding a NOT NULL column to a table. If the table contains data (as most database tables do), you can't just add a NOT NULL column, as Oracle doesn't know what value to put in the new column for existing rows - the DDL statement will fail. There are actually 3 separate scenarios for this problem that have separate solutions within the engine: Adding a NOT NULL column to a table without a rebuild Here, the workaround is to add a column default with an appropriate value to the column you're adding: ALTER TABLE tbl1 ADD newcol NUMBER DEFAULT <value> NOT NULL; Note, however, there is something to bear in mind about this solution; once specified on a column, a default cannot be removed. To 'remove' a default from a column you change it to have a default of NULL, hence there's code in the engine to treat a NULL default the same as no default at all. Adding a NOT NULL column to a table, where a separate change forced a table rebuild Fortunately, in this case, a column default is not required - we can simply insert the default value into the rebuild SELECT clause. Changing an existing NULL to a NOT NULL column To implement this, we run an UPDATE command before the ALTER TABLE to change all the NULLs in the column to the required default value. For all three, we need some way of allowing the user to specify a default value to use instead of NULL; as this is essentially the same problem as datatype conversion (inserting values into the sync script), we can re-use the UI and engine implementation of datatype conversion values. We also provide the option to alter the new column to allow NULLs, or to ignore the problem completely. Note that there is the same (long-running) problem in SQL Compare, but it is much more of an issue in Oracle as you cannot easily roll back executed DDL statements if the script fails at some point during execution. Furthermore, the engine of SQL Compare is far less conducive to inserting user-supplied values into the generated script. As we're writing the Schema Compare engine from scratch, we used what we learnt from the SQL Compare engine and designed it to be far more modular, which makes inserting procedures like this much easier.

• Pantheon Not Completely Installed?

  - by Simon

  I have just installed the pantheon shell today, and I have not found any help with this yet. I am not just a random noob, i use a bunch of other shells and i also have a few development applications on my copy of ubuntu. But ever since ive opened up pantheon, i cannot find settings or this thing called the launchpad. (if the launchpad is the app drawer up in the upper left corner, or if its the dock. i have it, if thats not what launchpad is, then i cant access it.) I can only change my wallpaper by going back to unity, gnome, or KDE. There is a system settings in the power menu (upper right), but it only has Language Support, Ubuntu One, Additional Drivers, And Printing. I can still access the full ubuntu settings in GNOME of Unity. But thats it. I installed in the terminal, uninstalled, and reinstalled using the software center. Please Help Me If Any Of You Can! Thanks!!!

• Can I show a table of one custom variable against another?

  - by Simon

  We have a number of custom variables set up in google analytics. We'd like to show a table of event occurrences broken down by two custom variables, e.g. if variable one can be A, B, or C and variable two can be J, K or L: Events | A | B | C | -------+-----+-----+-----+ J | 345 | 65 | 12 | K | 234 | 43 | 7 | L | 123 | 21 | 4 | -------+-----+-----+-----+ How do I get the information in that format?

• How should I track multi-valued page attributes (e.g. tags) using custom variables?

  - by Simon

  Our pages can each have many tags, e.g 'football', 'sms', 'nsfw', etc.. wich we would like to track in google analytics. We're already tracking things like category using google analytics custom variables. We've used three of the five available slots so far. How can we track tags the same way? If we just mush them all together - e.g. 'football, sms, nsfw' then can we track the ones that are tagged 'football'? What's the right way to track multi-valued page attributes using custom variables?

• loss of sound in ubuntu 12.04

  - by Leo Simon

  I'm running Linux E6520 3.2.0-56-generic #86-Ubuntu SMP Wed Oct 23 09:20:45 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux on a Dell Latitude E6530. (This is a new machine; have run the same version of linux on an older machine for a year, without this happening.) I've been losing sound regularly, though have not been able to isolate the trigger for this. I've scoured the web on this subject, in particular https://help.ubuntu.com/community/SoundTroubleshootingProcedure and Audio stopped working suddenly in 12.04 Nothing from the first site seemed to work for me. From the second site, I learned enough to be able to fix the problem when it happens, but nothing on the web has helped me figure out why the problem is happening in the first place. Patching together stuff from the web, and with some blind luck, I've found that the following steps seem to restore sound pulseaudio --kill pulseaudio --start pavucontrol -> output devices Click on the "Mute audio" icon, which mutes audio Click on the "Mute audio" icon, which unmutes audio. This obviously doesn't make sense: audio wasn't muted in the first place, but somehow, magically, toggling mute audio off and on seems to reset something. Can anybody suggest from this information why sound would be disappearing in the first place (it seems as though something is getting muted at the system level, but I don't know what)? a simpler (command-line/script) way of restoring sound, in particular, is it possible to reset pavucontrol from the commandline? Some other pieces of information that may be of use: The problem is clearly happening at the system level, since I've set up a clean new user, and this user has the same problems that I do. So user fixes like deleting the .pulse directory aren't (and don't) help. Sound works fine in Windows (dual-boot) so it's not a hardware problem Any help/suggestions on this would be most appreciated.

• I think "/lib/modules/$(uname -r)/build" points to incorrect folder

  - by Simón

  I compile/create my own deb packages of kernel with: make-kpkg --rootcmd fakeroot --initrd --append-to-version=$version --revision=1 kernel_image kernel_headers But when I install both packages, in /lib/modules/(*name_kernel_compiled*) it creates two links, sources and build, pointing to folder with sources, from I've compiled. sources link is correct but build should point to /usr/src/linux-(version kernel), don't you think?

• Color distortion with Intel HD4000 over HDMI output - VGA is fine

  - by Simon Möller

  I set up a new system with i5 3570k gigabyte z77 d3h using integrated graphics (HD4000) and I've installed the 64bit Desktop version of 12.04. Connected to my Acer Screen via HDMI, the colors are horribly distorted. I think the biggest issue is that black appears as greenish. Over VGA everything is fine. Interestingly, I once observed that connecting both, the VGA and the HDMI cable at the same time, solved the issue. Ubuntu thought 2 screens were connected, I mirrored the image, and over HDMI the colors looked fine. However, after a reboot I am now unable to reproduce this behavior. I read frequently, that Intel hardware should be supported out of the box by Ubuntu but it doesn't seem to be the case here. Should I upgrade my Kernel? If so, which version would you recommend? Thank you for your answers!

• Multiple contacts with shared information

  - by Keith Thompson

  Background: I currently have several hundred contacts, synchronized between a Microsoft Exchange server and several mobile devices. I also save exported copies of the contacts in .vcf format. Is there a good way (application, file format, whatever) to maintain contacts with shared information? A very common scenario is that I have contacts for two or more people who live in the same house, for example: John Doe 123 Main Street, Anytown USA Home: 555-555-1111 Work: 555-555-2222 Mobile: 555-555-3333 E-mail: [email protected] Jane Doe 123 Main Street, Anytown USA Home: 555-555-1111 Work: 555-555-4444 Mobile: 555-555-5555 E-mail: [email protected] As you can see, both contacts have the same home address and phone number, but distinct names and work and mobile phone numbers. (Other information might also be either shared or distinct.) The applications and file formats I'm familiar with don't seem to have a good way to deal with this. If I use a single "John & Jane Doe" contact for both, it's difficult to distinguish the distinct information (if I want to call Jane's mobile phone rather than John's). If I use a separate contact for each, I have to remember to update both of them (or all of them for N 2) when they move or change their home phone number. An ideal solution would let me create a record containing information for their household, and have each of their contact records contain a reference to the household record, so that when I view John's contact record I see both shared and distinct information. Is there anything out there that has good support this kind of thing? (I would think there would be, since it's a very common scenario.) (I suppose I could roll my own system that generates merged .vcf files from some extended format, but that wouldn't play well with synchronizing across multiple devices.)

• php-cgi cpu usage is super high

  - by Ryan Thompson

  I am getting constantly high and wildly fluctuating CPU usage % for php-cgi commands as seen via "top" on my Centos server.. I have a server density account and it seems that this is a common trend: User - PID - CPU % - MEM % - VSZ - RSS - TT - Stat - Started - Time - Command 500 - 6389 - 22.4 - 3 - 271136 - 32380 - ? - S - 20:26 - 0:40 - /usr/bin/php-cgi Seems there are about 6 or so of those records in my processes list at any given check-in. Any ideas what's causing this? I have fast_cgi installed and the module is loading.. Not sure why it isn't handling this though. Any help would be greatly appreciated! Ryan

• Eclipse grinds to a halt when building workspace

  - by Chris Thompson

  Hi all, This is a bit of a vague question because, frankly, I don't even know where to begin diagnosing the issue. My eclipse (Galileo) installation grinds to a complete halt when it's building the workspace -- to the point where I can't even type. I know the Android SDK I have installed is a major culprit because I can watch the memory usage go through the roof (through the built-in heap monitor) when the Android SDK content loader starts up. Every time I save a file though, the program just stops. The message at the bottom of the screen says Building workspace (74%) and sits there for about 30 or so seconds before completing and returning the performance to normal. I have a few other plugins installed (Maven, SVN, etc) but I'm assuming the main issue is Android. Has anybody had similar issues or any luck correcting this sort of problem? If there's anymore information you think would be helpful, just let me know...I didn't want to do a core dump on this question... I'm running it on Windows 7 64-bit for what it's worth. Thanks! Chris

• Dual mode 802.11n PCI adapters

  - by Mike Thompson

  I have recently bought a DLink DIR-825 router. It is a dual mode (2.4GZ & 5GHZ) 802.11n wireless access point/router. What is a good PCI adapter to pair with it? DLink appear to only make one dual mode adapter, which is the DWA-160 USB adapter. They don't seem to have a PCI adapter in their range, which seems very strange. Do any of the other network manufacturers make a good dual mode adapter?

• Windows 7 login screen show only last user and "Other User" icons after profile problem.

  - by Mike Thompson

  I recently had a profile problem with my Windows 7 PC. My original profile in the registry had ".bak" appended to it and a new profile was created. I was unable to login with the new profile. I fixed this immediate problem by logging on in safe mode. This enabled me to restore my original profile. However, since that moment the login screen now operates differently. Instead of showing icons for all the users with accounts on the PC, it now only shows two icons. The first icon is the last user who logged on and the second icon always shows "Other User". I have tried several different solutions recommended by other people with similar problems, but none of them have fixed the problem. I think the person who started this thread has the same problem, but none of the proposed solutions helped him either. Any help much appreciated.

• Should I enabled 802.3x hardware flow control?

  - by Stu Thompson

  What is the conventional wisdom regarding 802.3x flow control? I'm setting up a network at a new colo and am wondering if I should be enabling it or not. My oh-cool-a-bright-and-shiny-new-toy self wants to enable it, but this seems like one of those decisions that could blow up in my face later on. My network: An HP ProCurve 2510G-24 switch A pair of Debian 5 HP DL380 G5's with built-in NC373i 2-port NIC LACP'd as one link. 9000 jumbo frames enabled. (Application) A pair of hand-built Ubuntu server with 4-port Intel Pro/1000 LACP'd as one link. 9000 jumbo frames enabled. (NAS) A few other servers with with single 1Gbps ports, but one with 100Mbps. Most of this kit is 802.3x. I've been enabling it as I go along, and am about to test the network. But as my 'go live' day nears, I am worried about the 802.3x decision as I've never explicitly used it before. Also, I've read some 10-year old articles out there on the Intertubes that warn against using flow control. Should I be enabling 802.3x hardware flow control?

• Client/server application RPC connection gets disconnected very frequently

  - by Chris Thompson

  I have a client/server application that uses RPC for the client to communicate with the server. Fairly regularly, I get an event in the Application log that the RPC connection was disconnected: Client callback failed ((0x80010108) ) I have the Windows Firewall disabled on both machines. I've even run the client on a second computer with a clean Windows XP install without any group policies. This has been going on for a long time and no one has been able to figure out why it's happening. The same client/server app works fine at other client locations. Any thoughts?

• Why is a FLAC encoded from a decoded MP3 bigger than the MP3?

  - by Ryan Thompson

  To be more precise than in the title, suppose I have a MP3 file that is 320 kbps. If I decompress it, then logically, all the data except for roughly 320 kilobits out of each second of audio should be redundant data, able to be compressed away. So, when I encode the decompressed file to FLAC, or any other lossless codec, why is it so much larger? On a related note, is it theoretically possible to losslessly recover the source mp3 audio from a decompressed wav? (I know the mp3 itself is lossy. I'm asking if it's possible to re-encode without any further loss.) EDIT: Let me clarify the related question, and the rationale behind it. Suppose I have a wav that was decompressed from an MP3 file (and assume I don't have the mp3 itself for some reason). If I don't want to lose any more quality, I can re-encode it with FLAC or any other lossless encoder and get a larger file just to maintain the same quality. Or, I can re-encode it to mp3 again and get the same size as the original but lose more data. Obviously, neither of these cases is ideal. I can either have the original size or the original quality, but not both (I mean the quality of the original mp3, not the original lossless source). My question is: Can we get both? Is it theoretically possible to recover the lossy compressed data from the lossy decompressed data, without losing even more? If it is possible, I could imagine a lossless compression algorithm that compresses the audio with FLAC. Then it also scans the audio for any signs of previous lossy compression, and if detected, recompresses it losslessly to the original lossy file. Then it keeps whichever file is smaller.

• Why are FMS logs filled with 'play' event status code 408 for a failed webcast?

  - by Stu Thompson

  Recently we had a live webcast event go horribly wrong. I'm doing the technical post-mortem, with limited information. We know that the hardware encoder (a Digital Rapid Touch Stream Web HDI) was unable to send upstream at a sustained reliable high rate. What we don't know is if the encoder's connection was problematic (Zürich), or that of the streaming server (in Frankfurt). Unfortunately, I've got three different vendors all blaming each other (the CDN who runs the server, the on-site ISP and the on-site encoding team.) In the FMS log files I see a couple of interesting things: Zillions of Status Code 408 on play event entries for clients. Adobe's documentation stats that this "Stream stopped because client disconnected". ("Zillions" would be a ratio of 10 events for every individual IP address.) Several unpublish / (re)publish events per hour for the encoder I'd like to know if all those 408s could tell me with authority that the FMS server was starved for bandwidth, or that the encoding signal was starved (and hence the server was disconnecting clients.) Any clues?

• How can I run Gnome or KDE locally in Cygwin?

  Apparently it is possible to do this using cygwin ports, as can be seen in screenshots. I followed this how-to to get apt-cygports set up, and I used it to install gnome-session.

• Mac Mini drive problems but SMART verified: bad hard drive or controller?

  - by Zac Thompson

  I have a 3-year-old Intel Mac Mini at home. About a month ago, it stopped booting from the hard drive (internal, SATA, 80GB). I tried booting from the Install Disc to repair the filesystem but Disk Utility was unable to do so ("invalid node structure"). I was also unable to use the hard drive in the Terminal from the Install Disc nor from an Ubuntu boot CD ("DRDY err"). I could see the contents of some directories, but others would give an error and I would get failures when trying to copy files. At this point I was sure the filesystem was hosed and I'd want to reformat at least. DiskWarrior was able to let me retrieve the data files I was interested in, which are now copied to an external hard drive, but it reported a high number of problems ("speed reduced by disk malfunction" count was over 2000) when in the process of trying to rebuild the directory for the drive. It also would not let me use the rebuilt directory to replace the one on the drive; it claimed the disk errors prevented recovery in this way. Under normal circumstances I would now assume that the drive itself was going bad: DiskWarrior's "disk malfunction" error above is supposed to imply hardware problems. My initial plan was to buy a replacement for the internal 2.5" drive. However: Disk Utility, command-line tools and DiskWarrior had reported all along that the SMART status of the drive was okay/Verified. So I'm now worried that the drive hardware is actually fine, and that the problems were due to a disk controller that has gone "bad" somehow. If this is the case, I'll probably just replace the whole computer. Any advice on how I can tell what is to blame? I don't have a lot of extra hardware sitting around, so I don't have the option of simply dropping the drive in another machine or popping another hard drive inside the Mini.
