  • What happened to Alan Cooper's Unified File Model?

    - by PAUL Mansour
    For a long time Alan Cooper (in the 3 versions of his book "About Face") has been promoting a "unified file model" to, among other things, dispense with what he calls the most idiotic message box ever invented - the one the pops up when hit the close button on an app or form saying "Do you want to discard your changes?" I like the idea and his arguments, but also have the knee-jerk reaction against it that most seasoned programmers and users have. While Cooper's book seems quite popular and respected, there is remarkably little discussion of this particular issue on the Web that I can find. Petter Hesselberg, the author of "Programming Industrial Strength Windows" mentions it but that seems about it. I have an opportunity to implement this in the (desktop) project I am working on, but face resistance by customers and co-workers, who are of course familiar with the MS Word and Excel way of doing things. I'm in a position to override their objections, but am not sure if I should. My questions are: Are there any good discussions of this that I have failed to find? Is anyone doing this in their apps? Is it a good idea that it is unfortunately not practical to implement until, say, Microsoft does it?

  • Quick Outline: Navigating Your PL/SQL Packages in Oracle SQL Developer

    - by thatjeffsmith
    If you’re browsing your packages using the Connections panel, you have a nice tree navigator to click around your packages and your variable, procedure, and functions. Click, click, click all day long, click, click, click while I sing this song… But What if you drill into your PL/SQL source from the worksheet and don’t have the Tree expanded? Let’s say you’re working on your script, something like - Hmm, what goes next again? So I need to reacquaint myself with just what my beer package requires, so I’m going to drill into it by doing a DESCRIBE (via SHIFT+F4), and now I have the package open. The package is open but the tree hasn’t auto-expanded. Please don’t tell me I have to do the click-click-click thing in the tree!?! Just Open the Quick Outline Panel Do you see it? Just right click in the procedure editor – select the ‘Quick Outline’ in the context menu, and voila! The navigational power of the tree, without needing to drill down the tree itself. If I want to drill into my procedure declaration, just click on said procedure name in the Quick Outline panel. This works for both package specs and bodies. Technically you can use this for stand alone procedures and functions, but the real power is demonstrated for packages.

  • vsftpd: chroot_local_user causes GNU/TLS-error

    - by akrosikam
    Distro: Ubuntu 12.04.2 Server 32-bit Server client: vsftpd 2.3.5 (from default "main" repository) Problem: Since upgrading from Ubuntu 10.04 to Ubuntu 12.04 (nothing changed on client-side), vsftp has refused to make chroot-jails with the "chroot_local_user" directive on FTP(e/i)S-connections. Here's my vsftpd.conf: anonymous_enable=NO local_enable=YES write_enable=YES local_umask=022 dirmessage_enable=YES xferlog_enable=YES xferlog_std_format=YES ftpd_banner=How are you gentlemen. listen=YES pam_service_name=vsftpd userlist_enable=YES userlist_deny=NO tcp_wrappers=YES connect_from_port_20=YES ftp_data_port=20 listen_port=21 pasv_enable=YES pasv_promiscuous=NO pasv_min_port=4242 pasv_max_port=4252 pasv_addr_resolve=YES pasv_address=your.domain.com ssl_enable=YES allow_anon_ssl=NO force_local_logins_ssl=YES force_local_data_ssl=YES ssl_tlsv1=YES ssl_sslv2=NO ssl_sslv3=NO rsa_cert_file=/home/maw/ssl_ftp_test/vsftpd.pem rsa_private_key_file=/home/maw/ssl_ftp_test/vsftpd.pem debug_ssl=YES log_ftp_protocol=YES ssl_ciphers=HIGH chroot_local_user=NO How to reproduce: Have a working SSL/TLS-secured vsftpd-configuration (I suggest similar to the one above) ready. Try to connect with an FTP user client and upload some files. With my setup, the above listed config works well at this point. Edit /etc/vsftpd.conf and set chroot_local_user= to YES. Make sure that chroot_list_enable= and/or chroot_list_file= are not set. Comment them out if they are. Save and exit. Run sudo restart vsftpd (or sudo service vsftpd restart if you like) in a terminal. Try to connect with an FTP user client. You should see a message more or less like this: GnuTLS error -15: An unexpected TLS packet was received. This is an issue for me, as I do not want FTP-sessions to be able to list files outside the user's home folder. I have checked with several client-side apps, and I get the same results with every one of them. Filezilla is not so good regarding cipher methods nowadays, but as I am able to make an FTP(e)s-connection over TLS (as long as chroot'ing is disabled and ssl_ciphers is set to HIGH) I have a feeling ciphers are not the issue this time, and that I won't find the answer by tweaking configs on the client side. My vsftpd.log stays empty, even though debug_ssl and log_ftp_protocol are enabled, so no info there either.

  • Change in Job Title and Responsibilities

    - by John Conwell
    I've spent the past 7 years focused primarily on code and database performance.  It's an area that I have a passion for, as well as a propensity.  But what I've found is that its very hard to change the culture of a development environment.  You can teach performance, you can encourage performance, you might see slight shift in how devs think about performance.  But without full management backing and support you wont get long lasting changes in the development culture.  And in the end, you are back to being the "Perf Guy", fixing performance design flaws, after the fact, one by one by one. Which is why last year I asked my boss to changed my title and responsibilities to more naturally align with the team I was working for.  So now I'm a Computing Research Engineer (vague, I know), researching in the field of Big Data analytics and visualization. I've found this change revitalizing and a lot of fun.  And given the nature of Big Data (its, um…big) the performance aspects are always ever present.

  • Server 2008 R2 How to Change Windows 7 Basic Theme Color

    - by Wes Sayeed
    We're deploying thin clients connecting to a terminal server farm. The computers have high visibility to the public and I would like them to at least look presentable and not like something out of 1995. So I installed the Desktop Experience feature and enabled the Theme service. The server will not support Aero because it has no 3D graphics, but we can enable the Windows 7 Basic theme, which has the Aero look without the 3D effects. The problem with that theme is that you can select any window color you want, as long as it's baby boy blue. Is there a way to make those windows another color? The window color controls do nothing.

  • Please help me, I need some solid career advice, put myself in a dumb situation

    - by Kevin
    Hi, First off, I just want to say thank you in advance for looking at my question and would really value your input on this subject. My core question is how do I proceed from the following predicament. I will be honest with you, I wasted my College Experience. I slacked off and didn't take any of my comp sci classes that seriously, somehow i still got out with a 3.25 GPA. But truth be told I learned nothing. I befriended most of my professors who went pretty lenient on me in terms of grading. However, I basically came out of College knowing how to program a simple calculator in VB.Net. I was (to my great surprise) hired by a very large respected company in Denver as a Junior developer. Well the long and the short of it is that I knew so little about programming that I quickly became the office pariah and was almost fired due to my incompetence. It has been 8 months now and I feel I have learned some basic things and I am not as picked on as I used to be by the other developers. However, everyone hates me and the first few months have given the other developers a horrible perception of me. I am no longer afraid of code or learning, but I have put my self in the precarious position of being the scapegoat of our department. I hate going to work every day because no one there is my friend and pretty much everyone is hostile to me. What should I do? Any advice?

  • What is the best distro to host a KVM virtualization solution

    - by elventear
    I am looking for a Server oriented distro that we can expect have decent support but also offer as much as possible some of the latest features that KVM might offer. I am leaning towards Ubuntu LTS 10.04, because well it's LTS and more bleeding edge, but I find Ubuntu not serious enough in terms of support (I say this a heavy Ubuntu user). Given that Centos 6 is not out yet, I am not sure if going Centos 5 would be the best option in terms of getting more features from KVM. Any other distro you would recommend that could meet the criteria of long term support? (At least 4 years)

  • Ubuntu Remix on Acer Aspire One Netbook keeps freezing

    - by user7553
    It came with a Windows XP installation and I just couldn't deal with the screen constantly blacking out. Later on I found out they designed a specific key on this netbook for it. Anyways I installed Ubuntu Remix and it fixed it. However a lot of bad things are happening now. 1) If I want a long video or lots of music it will lockup after an hour. 2) Plugging it to an external monitor for more then 1 hour will black out. 3) Constantly running fsck after a lockup and then I lose nodes / fragments and what not :( I am really not sure what to do, both blacking out and lockups really mess my hard drive up. I have to manually run fsck every time it happens. My gf has the same kind of netboot w/ Remix (not the same model number) and it runs perfectly fine on hers. Except for skype eating up all her CPU.

  • What is the 64-bit Firefox Beta PPA?

    - by JamesTheAwesomeDude
    I recently discovered that my computer is 64-bit. I have backed up my Home folder, and reinstalled Ubuntu. The reinstall wasn't nearly as painful as I thought. There is one thing that I can't quite seem to figure out: how do I get the 64-bit Firefox Beta build? I always get the Beta builds, but I want to take advantage of the 64-bit architecture of my computer. this page says that Mozilla has come out with a 64-bit version of Firefox, but I can't seem to find it. I do understand the ramifications of using a 64-bit browser, but I've decided to jump right in and do it anyway. (Flash and Java are already 64-bit, and who cares about Silverlight, since it's not for Linux anyway?) There's only one issue, and it's a big one: I can't find the 64-bit Beta PPA!!! (I really hate using .tar.gz files, but I'd be willing to do that as long as I could still access Firefox via the Launcher. Oh, speaking of which, I don't understand .tar.gz files. Once, I managed to run one (the Dropbox Beta build,) but I have no idea whatsoever on how to install them: as in, click on the icon and go.)

  • Sending cron output to a file with a timestamp in its name

    - by Philip Morton
    I have a crontab like this on a LAMP setup: 0 0 * * * /some/path/to/a/file.php > $HOME/cron.log 2>&1 This writes the output of the file to cron.log. However, when it runs again, it overwrites whatever was previously in the file. How can I get cron to output to a file with a timestamp in its filename? An example filename would be something like this: 2010-02-26-000000-cron.log I don't really care about the format, as long as it has a timestamp of some kind. Thanks in advance.

  • Removing connections to network printers that no longer exist

    - by Jeff Hardy
    I'm trying to delete some network printer connections from a Windows Server 2003 (SP2) machine because the printer shares no longer exist. Windows shows the printers' status as "Printer not found on server, unable to connect"; this is expected; the printers are now on a different server. Only one machine ever connected to the printer shares; it no longer needs to and I'd like to clean it up. However, when I try to delete the connections, I get an error message: --------------------------- Remove Printer --------------------------- Printer connection cannot be removed. Operation could not be completed. --------------------------- OK --------------------------- The "solutions" I've found online seem to be more voodoo than anything (and they still don't work!). Does anybody know how I can delete these long-gone printers?

  • C#.NET vs VB.NET, Which language is better?

    Features I cannot say any language good or bad as long as it's compiler can produce MSIL can run under .NET CLR. If someone says C# has more futures, you can understand that those new features are of C# compiler but not .NET, because if C# has a specific future then CLR cannot understand them. So the new features of C# will have to convert to the code understood by CLR eventually. that means the new features are developed for C# compiler basically to facilitates the developer to write their code in better way. so that means no difference in feature list between C# and VB.NET if you think in CLR perspective. Ease of writing Code I feel writing code in C# is easy, because my background is C and C++, Java, syntaxes very are similar. I assume most developers feel the same. Readability But some people say VB.NET code most readable for the members who are from non technical background, because keywords are generally in English rather special charectors. No of Projects in Market I assume 80 percent of market uses C# in their .NET development. for example in my company many projects are there .nET and all are using C#. Productivity & Experience though the feature list is same, generally developers wants to write code in their familiar languages. because it increase the productivity. Hope this helps to choose the language which suits for you. span.fullpost {display:none;}

  • iPhoto fails to see my new iPhone 3Gs

    - by Alexey Kulikov
    Two weeks ago I have bought the new iPhone 3Gs. It synced like charm with iTunes and I was happy until a couple of days ago when I noticed that there was absolutely no way I could get any photos from the phone to my mac, as it doesn't even appear in the device list. Long story short — i have even tried resetting Leopard completely from scratch (and formatting the HD beforehand). Still no joy. Leopard Snow 10.6.1 absolutely clean install with all updates iPhone 3Gs 3.1.2 - syncs like charm with iTunes, but NOT iPhoto Mac Book Air Any help will be greatly appreciated! update: It works with my old iphone, why can't the 3Gs work?

  • Cablemodem frequent connection loss

    - by LVDave
    I have a Linksys BEFCMU10 cablemodem and a WRT54GL router with Tomato 1.27 firmware on Cox cable. My question is this: I get what seems to be random disconnects from the internet, where the cable modem lights are still normal, but I can connect nowhere, either via a url or an ip address. At the same time these disconnects are happening, I can go to the router's Tomato management webpage, and release/renew my external IP address from Cox's DHCP server. I've had Cox look at the signal levels on the cable modem, and they say they look fine. What brings back the modem, for sometimes as long as 17 days, is several power-cycles of the modem. I don't understand the underlying cable modem technology too well, but I do know that if I'm able to release/renew the DHCP-provided WAN address, I'd expect that the cable modem was working ok... Anybody have any ideas??

  • Terribly slow Apache2 on VM Virtualbox

    - by cadavre
    I just launched VM Virtualbox with guest Ubuntu Server on host Windows 8. Both 64bit. Everything works perfectly fine. Maybe it's because I'm not using any X... Htop shows ~25% of memory usage, everything is fine, but not Apache2. Normally it's fine, but when I send request from my browser on host (networking mode set to Bridge mode), Apache2 is turning into 1-minute-long loading process with 100% CPU time. Any ideas how to debug it? Any ideas about solving this throat problem?

  • Unhappy with performance of GBit Ethernet to Fiber converter

    - by Aaron Digulla
    I just bought a TP-Link MC200CM GBit Ethernet (1000-T) to Fiber (1000-SX) media converter. The device works but I'm unhappy with the performance: When connecting my computer over 1000-T (twisted pair, Cat 6, 18meters) with my server, I get a throughput of about 610MBit/s. If I replace the cable with two media converters, I'm left with about 310-315MBit/s (i.e. half the performance). My setup is like this: Computer <- GBit switch <- long cable <- GBit switch <- server Computer <- GBit switch <- MC200CM <- 30m fiber <- MC200CM <- GBit switch <- server Is there a way to improve the performance? Will another MC be faster? Or is that about as much as I can expect with the additional 2 converters?

  • What are the options for hosting a small Plone site?

    - by Tina Russell
    I’ve developed a portfolio website for myself using Plone 4, and I’m looking for someplace to host it. Most Plone hosting services seem to focus on large, corporate deployments, but I need something that I can afford on a very limited budget and fits a small, single-admin website. My understanding is that my basic options are thus: I can go with a hosting service that specifically provides Plone. I know of WebFaction, but what others exist? Also, I’d have two stipulations for a Plone hosting service: (a) It needs to use Plone 4, for which I’ve developed my site, and (b) it needs to allow me SSH access to a home directory (including the Plone configuration), so that I may use my custom development eggs and such. I could use a VPS hosting service. What are my options here? Again, I need something cheap and scaled to my level. I could use Amazon EC2 or a similar service (please tell me of any) and pay by the tiniest unit of data. I’m a little scared of this because I have no idea how to do a cost-benefit analysis between this and a regular VPS host. The advantage of this approach would be that I only pay for what I use, making it very scalable, but I don’t know how the overall cost would compare to any VPS host under similar circumstances. What factors enter into the cost of Amazon EC2? What can I expect to pay under either option for regular traffic for a new website? Which one is more desirable for when a rush of visitors drive up my bandwidth bill? One last note: I know Plone isn’t common for websites for individuals, but please don’t try to talk me out of it here; that’s a completely different subject. For now, assume I’m sticking with Plone for good. Also, I have seen the Plone hosting services list on Plone.org—it’s twenty pages long, and the first page was nothing but professional Plone consulting services that sometimes offer hosting for business clients. So, that wasn’t much help. Thank you!

  • Felix Baumgartner Skydives from the Edge of Space [Video]

    - by Jason Fitzpatrick
    Yesterday Felix Baumgartner broke the record for highest skydive by leaping out of a capsule 128,100 feet above the Earth. Check out his jump in the following videos. After flying to an altitude of 39,045 meters (128,100 feet) in a helium-filled balloon, Felix Baumgartner completed a record breaking jump for the ages from the edge of space, exactly 65 years after Chuck Yeager first broke the sound barrier flying in an experimental rocket-powered airplane. Felix reached a maximum of speed of 1,342.8 km/h (833mph) through the near vacuum of the stratosphere before being slowed by the atmosphere later during his 4:20 minute long freefall. The 43-year-old Austrian skydiving expert also broke two other world records (highest freefall, highest manned balloon flight), leaving the one for the longest freefall to project mentor Col. Joe Kittinger. The above video is a 2 minute highlight reel of the ascent and jump; check out the full 15 minute descent video here.

  • Idiomatic way to invoke chef-solo?

    - by kerkeslager
    What is the idiomatic way to invoke chef-solo? Most sites do this: chef-solo -c ~/solo.rb -j ~/node.json -r http://www.example.com/chef-solo.tar.gz But that's long. There are a few shorter ways to do this that I can think of: A rake task (rake chef-solo). A small shell script (run-chef-solo). An alias (can override the name, like chef-solo). What is the idiomatic way to do this? How are other chef users invoking chef?

  • Black GUI with minimal desktop icons appeared after powering on my desktop PC

    - by Christopher Chipps
    My computer powered on fine but after POST, a dialog box appeared with a red "X" and it gave some sort of warning. It had a long file name, I cannot recollect the entirety of it but it was something like C:/system32/desktop....After clicking ok, the GUI was totally black with only the Recycle Bin icon in the Desktop, and the Taskbar was there as well. I restarted it, and the GUI was back to normal with the icons and wallpaper in their proper place. I'm sure if I knew more of that file name in the dialog box, that would be helpful to those reading this but should I be concerned that this happened?

    I'm following what should be simple instructions to enable LDAP SSL on our domain controller (instructions here). Duplicating the Kerberos certificate is successful however, when attempting to select "Certificate Template to Issue", the created certificate does not appear. What gives? A long time ago, I actually completed this step on a now decommissioned DC with no problem. Our environment is Windows Server 2008 Standard, and we have two domain controllers. Only one has the role of certificate authority. I look forward to any help here, thank you ahead of time.

  • Xamarin Designer for Android Article

    - by Wallym
    The latest version of Mono for Android includes a long-awaited design surface. Learn how it works.It's interesting to look at the needs of various segments of developers. When I first start looking at an environment, the first thing I need to understand is the UI. I'm not magically born with some knowledge about the environment and don't learn well by just reading, so I need some help in getting started. I found this was true when I started Windows based development in the early 1990s, Dynamic Web in the late 1990s, ASP.NET in 2000, Silverlight/WPF, iPhone and Android. I find that getting up to speed with a UI is the single biggest deterrent for someone learning a platform. I find that as a beginner I need the features provided by a design surface. It's only as I grow and become comfortable with a platform that I find that building a UI by hand is more productive. Even as I get more advanced, I still can learn from a designer, so it has value as I grow into a platform.I hope that this article helps you as you dive into Android Development.

  • Is It Possible To Recover A Partial LVM Logical Volume?

    - by Terry Wang
    Background It is an Ubuntu 12.04 VirtualBox VM with 5 virtual HDDs (VDI), NOTE this is just a test VM, so not well planned ahead: ubuntu.vdi for / (/dev/mapper/ubuntu-root AKA /dev/ubuntu/root) and /home (/dev/mapper/ubuntu-home) weblogic.vdi - /dev/sdb (mounted on /bea for weblogic and other stuff) btrfs1.vdi - /dev/sdc (part of btrfs -m raid1 -d raid1 configuration) btrfs2.vdi - /dev/sdd (part of btrfs -m raid1 -d raid1 configuration) more.vdi - /dev/sde (added this virtual HDD because / ran out of inodes and it wasn't easy to figure out what to delete so as to free up inodes, so I just added the new virtual HDD, created PV, added it to existing volume group ubuntu, grew the root logical volume to work around the inode issue -_-) What happened? Last Friday, before finishing up I wanted to free up some disk space on that box, for some reason I thought the more.vdi was useless and tried to detach it from the VM, I then clicked delete (should have clicked keep files damn!) by mistake when detaching. Unfortunately I didn't have backup for it. All too late. What I have tried Tried to undelete (use testdisk and photorec) the vdi files but it takes too long and recovered heaps of .vdi files that I didn't want (huge, filled the disk, damn!). I finally gave up. Fortunately most of data is on separate ext4 partition and btrfs volumes. Out of curiosity, I still tried to mount the logical volumes and see if it is possible to at least recover the /var and /etc I tried to use system rescue cd to boot and activate the volume groups, I got: Couldn't find device with uuid xxxx. Refusing activation of the partial LV root. Use --partial to override. 1 logical volume(s) in volume group "ubuntu" now active. I was able to mount home LV but not root LV. I am wondering if it is possible to access the root LV any more. Under the bonnet, data (on LV root - /) was striped to more.vdi (PV), I know it's almost impossible to to recover. But I am still curious about how system administrator/DevOps guys deal with this sort of situation;-) Thanks in advance.
