  • Bash - Adding 0's in the middle of a file name

    - by user596691
    I have a bunch of files which are named: mem0.csv mem1.csv . . . . mem153.csv . . . They are all in the same folder. When I do ls in the folder they appear in an order of mem0.csv mem1.csv mem10.csv mem100.csv . . . mem2.csv mem20.csv . . . I want to create a bash script to push 0's between mem and the number. I figure that I need to add 0's until all the filenames are of the same length only problem is that I don't know how to do this.

  • remove a varchar2 string from the middle of table data values

    - by Michelle Daniel
    Data in the file_name field of the generation table should be an assigned number, then _01, _02, or _03, etc. and then .ldf (example 82617_01.pdf). Somewhere, the program is putting a state name and sometimes a date/time stamp, between the assigned number and the 01, 02, etc. (82617_ALABAMA_01.pdf or 19998_MAINE_07-31-2010_11-05-59_AM.pdf or 5485325_OREGON_01.pdf for example). We would like to develop an SQL statement to find the bad file names and fix them. In theory it seems rather simple to find file_names that include a varchar2 data type and remove it, but putting the statement together is beyond me. Any help or suggestions apprecuiated. Something like ........... UPDATE GENERATION SET FILE_NAME (?) WHERE FILE_NAME (?...LIKE '%STRING%');?

  • How can I improve these online java programming puzzles I wrote for my (middle/high school) students?

    - by Arcymag
    I'm teaching some middle and high school students programming right now, and I found that some of them really liked online programming puzzles. So I created http://www.kapparate.com/coder/ , and right now there's 4 categories of puzzles. All the puzzles are set up right now so that variables are pre-initialized, and the user plugs in some code in the middle. For example, the problem might say these are pre-initialized: int x = ????; int y = ????; int z; and then the program might ask the student to write the final line of code: z = x + y;. Now I know I could go a long way in improving the usability of this site (like having an area that lists the pre-defined variables), but I was wondering if this concept seems sound. I know some sites have kids fill in functions, but not all of my students know what functions are yet, and I'm trying to introduce online programming puzzles before that.

  • Chrome: middle mouse button overriden on certain web pages?

    - by buli
    Normally when I click on a link in Chrome with a middle mouse button, the page open s in a new tab. I find it useful and would like it to always work that way. But on some sites, specifically SharePoint sites I'm often working with, middle click on certain links opens the page in the same tab. Example can be found on this publicly available SharePoint demo page when clicking on "Internet Sites" or "SharePoint resources" links with middle mouse button. Those menu items seem like a link (they definitely have URL assigned). Why do them open in the same tab instead of a new one, when middle clicked? Can this behavior be changed in Chrome's settings or using some addon?

  • Setting up a transparent SSL proxy

    - by badunk
    I've got a linux box set up with 2 network cards to inspect traffic going through port 80. One card is used to go out to the internet, the other one is hooked up to a networking switch. The point is to be able to inspect all HTTP and HTTPS traffic on devices hooked up to that switch for debugging purposes. I've written the following rules for iptables: nat -A PREROUTING -i eth1 -p tcp -m tcp --dport 80 -j DNAT --to-destination 192.168.2.1:1337 -A PREROUTING -i eth1 -p tcp -m tcp --dport 80 -j REDIRECT --to-ports 1337 -A POSTROUTING -s 192.168.2.0/24 -o eth0 -j MASQUERADE On 192.168.2.1:1337, I've got a transparent http proxy using Charles (http://www.charlesproxy.com/) for recording. Everything's fine for port 80, but when I add similar rules for port 443 (SSL) pointing to port 1337, I get an error about invalid message through Charles. I've used SSL proxying on the same computer before with Charles (http://www.charlesproxy.com/documentation/proxying/ssl-proxying/), but have been unsuccessful with doing it transparently for some reason. Some resources I've googled say its not possible - I'm willing to accept that as an answer if someone can explain why. As a note, I have full access to the described set up including all the clients hooked up to the subnet - so I can accept self-signed certs by Charles. The solution doesn't have to be Charles-specific since in theory, any transparent proxy will do. Thanks! Edit: After playing with it a little, I was able to get it working for a specific host. When I modify my iptables to the following (and open 1338 in charles for reverse proxy): nat -A PREROUTING -i eth1 -p tcp -m tcp --dport 80 -j DNAT --to-destination 192.168.2.1:1337 -A PREROUTING -i eth1 -p tcp -m tcp --dport 80 -j REDIRECT --to-ports 1337 -A PREROUTING -i eth1 -p tcp -m tcp --dport 443 -j DNAT --to-destination 192.168.2.1:1338 -A PREROUTING -i eth1 -p tcp -m tcp --dport 443 -j REDIRECT --to-ports 1338 -A POSTROUTING -s 192.168.2.0/24 -o eth0 -j MASQUERADE I am able to get a response, but with no destination host. In the reverse proxy, if I just specify that everything from 1338 goes to a specific host that I wanted to hit, it performs the hand shake properly and I can turn on SSL proxying to inspect the communication. The setup is less than ideal because I don't want to assume everything from 1338 goes to that host - any idea why the destination host is being stripped? Thanks again

  • What program should I use for SSL stripping and re-encrypting

    - by Sparksis
    I'm trying to strip a HTTP over SSL connection down to SSL and then re-encrypt the channel (with a signed certificate(s) I can provide). Of course I want to be able to store captures of all the un-encrypted data. The purpose of this is to reverse engineer a HTTP handshake that is used by a SIP program on my machine. I've tried SSLstrip but it doesn't support what I need it too. Edit: I want something to this effect https://github.com/applidium/Cracking-Siri/blob/master/tcpProxy.rb only more generic and able to write to a pcap stream that wireshark will understand (I'm not sure if this does that). Edit2: upon further inspection this does not create pcap streams. I guess if need be I can write a compatible version but that is not the desired choice.

  • Open Source project that does SSL Inspection

    - by specs
    I've been assigned to research out and spec replacing our old and decrepit http content filtering system. There are several open source filtering packages available but I've not come across one that does SSL inspection. The new system will scale to many branches of different sizes, from say 10 users to a few hundred, so purchasing an appliance for each branch isn't desirable. When we're further along, we will do custom programming as we have a few unique needs in other aspects of filtering, so if the suggestion takes a bit of customization, it won't be a problem.

  • Auto-detected mouse - disable 3rd button enumation

    - by viraptor
    I'd like to disable the 3rd button emulation in ubuntu 9.10. Normally, I'd just change the option in xorg.conf and it would go away - but how do I deal with an autodetected mouse? For example, I've got a mouse I connect to USB and it has the emulation enabled by default. How do I change it in that case?

  • How do I disable mouse magnet on middle edge with multi monitors?

    - by piquadrat
    I use Ubuntu 12.04 on a two screen setup. Multiscreen on 12.04 has generally become much better, but there is one thing that really gets on my nerves: there's a mouse magnet of sorts on the middle edge (between the two screens). It's undoubtedly there to make it easier to interact with the launcher on the right screen. But I have enough trust in my mousing skills, the magnet is more annoying than helpful in my case. Can I disable it somehow?

  • Changing middle mouse behavior in Adobe AIR HTML Control?

    - by Qz
    I'm using the Flex 4/Adobe AIR mx:HTML control in a project and I'm trying to figure out how to change the middle mouse behavior. For some reason the control treats middle mouse clicks and drags exactly the same as left mouse clicks and drags, navigating through links and selecting text -- everything. For my project I need to use the middle mouse button for a different function. I've figured out how to hook into the events (although mouseUp and mouseDown for Left/Middle don't work over HTML whitespace, perhaps because of the default behavior). However I can't figure out how to stop the default behavior for middle mouse events. Calling preventDefault() on the HTML control mouse events doesn't work, presumably because the behavior is handled by the HTMLLoader within the HTML control, which I imagine hooks mouse events to the actual HTML content displayed on screen. Unfortunately I can't view the source for HTMLLoader to figure out what's going on, and browsing the properties and events doesn't shed any light on the situation either. Any help would be greatly appreciated! Oh, if anyone can suggest a different embeddable HTML renderer that doesn't have this problem, then that might work too, I'm not too tied to WebKit (although I do need to use AIR)

  • How to hide keys in application?

    - by WilliamKF
    I have a C++ client/server application where the client and server are my executable. Each time a connection is made between the client and server, I generate a new encryption key for that session and I wish to transmit this session key and encrypt this session key using a static key that is built into both the client and server. However, running strings on my executable reveals the static key. How can I hide the embedded static key in my client and server application so that they are not easily extracted and thus allowing someone to decode my session key.

  • Open an X application going through many hoops (SSH, vpn etc)

    - by ??O?????
    The players: my home computer, running Linux with an X server running. (Call it HOME.) a remote site, to which I can connect over the internet using a VPN. (SITE) a Linux computer at the remote site, to which I can connect with ssh -X and nicely have X clients displaying on my local server. (MIDDLE) a very old Irix machine (an Onyx) at the remote site, which has no SSH server (therefore I can't ssh -X to it), only an ssh client. (ONYX) Purpose I need to run an X11 application on the ONYX machine, and see the GUI on HOME. I think I stumble upon xauth issues. So far The current situation is: ? HOME connects to SITE ? A vncserver starts on MIDDLE:7 ? vncviewer on HOME connects to vncserver on MIDDLE ? ONYX starts a forwarding ssh session to MIDDLE: ssh -TfN -L 6007:127.0.0.1:6007 MIDDLE ? DISPLAY=localhost:7 xclient on ONYX fails with Xlib: connection to "127.0.0.1:7.0" refused by server I do know that the forwarding (6007:127.0.0.1:6007) succeeds. A previous attempt was: ? HOME connects to SITE ? HOME connects to MIDDLE: ssh -X MIDDLE (xclock displays on HOME, DISPLAY is 127.0.0.1:10) ? ONYX starts an SSH tunnel to MIDDLE: ssh -TfN -L 6010:127.0.0.1:6010 MIDDLE ? DISPLAY=127.0.0.1:10 xclient fails with X connection to 127.0.0.1:10.0 broken (explicit kill or server shutdown). while an error pops up in the MIDDLE session: X11 connection rejected because of wrong authentication. Despair How can I achieve my purpose?

  • radeon display driver clones monitors while using Xinerama

    - by gregmuellegger
    I'm trying to get my two Radeon HD 4770 cards working with three monitors. Xinerama works so far in the way that I have two fully working monitors were I can move windows from one to the other. My problem now is that my third monitor is a clone of my second monitor (displaying the exact same thing). These monitors are connected to the same graphic card ("Screen Middle" and "Screen Right" in the xorg.conf below). Here is my xorg.conf: Section "ServerLayout" Identifier "ThreeMonitors" Screen "Screen Left" 0 0 Screen "Screen Middle" RightOf "Screen Left" Screen "Screen Right" RightOf "Screen Middle" Option "Xinerama" EndSection Section "Monitor" Identifier "Monitor Left" Option "DPMS" EndSection Section "Monitor" Identifier "Monitor Middle" Option "DPMS" EndSection Section "Monitor" Identifier "Monitor Right" Option "DPMS" EndSection Section "Device" Identifier "Device Left" Driver "radeon" VendorName "ATI Technologies Inc" BoardName "ATI Radeon HD 4770 [RV740]" BusID "PCI:3:0:0" Screen 0 EndSection Section "Screen" Identifier "Screen Left" Device "Device Left" Monitor "Monitor Left" SubSection "Display" Depth 24 EndSubSection EndSection Section "Device" Identifier "Device Middle" Driver "radeon" VendorName "ATI Technologies Inc" BoardName "ATI Radeon HD 4770 [RV740]" BusID "PCI:2:0:0" Screen 0 EndSection Section "Screen" Identifier "Screen Middle" Device "Device Middle" Monitor "Monitor Middle" SubSection "Display" Depth 24 EndSubSection EndSection Section "Device" Identifier "Device Right" Driver "radeon" VendorName "ATI Technologies Inc" BoardName "ATI Radeon HD 4770 [RV740]" BusID "PCI:2:0:1" Screen 1 EndSection Section "Screen" Identifier "Screen Right" Device "Device Right" Monitor "Monitor Right" SubSection "Display" Depth 24 EndSubSection EndSection I'm using a fresh Kubuntu 10.10 installation with propsed-updates enabled since this repo contains a xorg fix for using multiple graphic cards.

  • Why does my Ubuntu freeze in the middle of something with a blank screen?

    - by mohamed
    I am facing a serious problem as my Dell Optiplex 745 loaded with Ubuntu 12.04 32bit freezes with a blank screen no mouse cursor no keyboard activity in many occasions. Sometimes when I open firefox, or software center, I really can't tell what the main problem is, but what i am certain about is it i have to do a hard reset to reboot. I tried to use a live-cd to boot but it did the same, tried the recovery console but couldn't find a way to fix from there (I am a new user) suspected a hardware problem but windows runs flawlessly so I believe its something related to ubuntu. Specs: Intel Celeron D 3.06 GHZ 3.0 GB ram Intel built in graphics Q965 1 TB HDD Bios Phoenex 2.6.4 Please help I really love ubuntu and I don't want to go back to windows!

  • Is medium-resolution a good middle ground for web images?

    - by ColdSharper
    I'm used to thinking of hi-res 300 ppi and above, and lo-res, 72 or 96. But today I got an image that was 240 ppi, and da boss wanted as high res as possible. It was a huge file, but when I resized down to 700px wide in PS, optimized jpeg with no compression, without changing the res the result was a 129KB file that looks decent on most browsers (at least my box...who knows about old monitors, etc.) Did I miss a conference when I was on a break? Are others doing medium-res?

  • Is it bad SEO to embed an img tag in the middle of a sentence?

    - by Offlein
    I recently received a web mockup that included a sidebar with a short paragraph of narrow text; a quote from a person. At the end of the quote, the mockup had a circular portrait of the person floated to the right, hanging off the edge of the block, with the text flowing around the edge of it. It looked like this, where "TEXT" is the text, and "o" is the portrait TEXTTEXTTEXTTEXTTEX TEXTTEXTTEXTTE TEXTTEXTTEXT ooooo TEXTTEXTTEXT ooooooo TEXTTEXTTEXT ooooooo ooooo The easiest way to do this would be to put the tag for the portrait somewhere in the markup of the text, and float it right. But the HTML will look like, in that case: TEXTTEXTTE<img src="..." style="float: right;">XTTEXTTEXT and I fear this would be bad for SEO. Does anyone know? The other option is putting the at the end, absolutely positioning it, and using manual line breaks -- which sucks for my responsive design.

  • Is there any problem with using two slashes in the middle of a URL? [closed]

    - by joshuahedlund
    Possible Duplicate: What does the double slash mean in URLs? I'm working on a mod_rewrite URL structure as follows: http://example.com/search/filter1/filter2/filter3/filter4 There are some conditions where it is OK for the first attribute to be blank, but i want to keep the other attributes in the same position. (Otherwise I can't assume that the attribute in the second position represents what I want it to represent.) However this results in some URLs like this: http://example.com/search//filter2/filter3/filter4 This seems to work in all browsers I've tested (Chrome,Firefox,IE9,IE compatible) and I'm not seeing any errors on the server side, so I can't think of any problems in using it. But it just looks wrong and weird to me and I'm not used to seeing it. Are there any potential downsides to using a structure that encourages URLs like this, or any major reasons no one seems to use it? (Everything I search in Google assumes I'm talking about the two slashes after http:)

  • Is there a middle ground in monthly server costs?

    - by user41655
    Right now I'm paying a monthly fee of 12.95 for a server and I'm definitely getting what I pay for! (no customer support, outages, slowdowns, glitches, etc) I know that the good companies (Rackspace) charge much more. (Hundreds a month) I'm wondering if there is a middle ground somewhere that might be as good as Rackspace but is still better than what I have. 50 a month maybe? If it does exist will the extra $40 a month be worth it?
