• How do I make zsh completion act more like bash completion?

  - by Tordek

  I'm a recent convert from bash to zsh (which I'm using "oh my zsh" with), but one thing annoys me: When I hit the tab key, the first autocompletion is filled out automatically, and you need to cycle through the completions by hitting tab repeatedly. This differs from bash, where you are just shown a list of the completions. If all completions have the same prefix, then this prefix is filled out. You can select the one you want by continuing to type. I find the latter preferable since it is faster to type, than to select a completion by hitting tab repeatedly. Is there any way to make zsh completion act more like bash in this regard?

• Trying to get a new user up on pfSense IPSec VPN; Config file import failed, now getting gateway err

  - by Chris

  Caveat: I am not a sysadmin, so please forgive the n00bness of the query. We have a new user and I'm trying to get them up on VPN. We use pfsense as an IPSEC endpoint. This person is using Shrewsoft for the client. I had created an entry in pfsense for them and then edited a previous user's config file. Shrewsoft didn't import the config file very well and I had to hand edit the information. Now we are getting gateway errors. One thing I've noticed is that there is a different between the values of the preshared key stored on the firewall and the psk stored in the config file. I assume it has something to do with a hash, but I've no idea if that's the case and whether that might be what's causing the problem. Any suggestions greatly appreciated! Tangentially, is there some software used to generate these config files?

• Postfix configuration w.r.t. port 25

  - by Monkey Boson

  After a considerable amount of research, I have configured my postfix server to use dovecot to accept SMTPS connections over port 465 and everything works swimmingly. Unfortunately, I forgot that, unless I listen to port 25, I'm not going to receive any e-mail from the net. I'm hoping somebody knows off the top of their head how to open up port 25 on Postfix for anonymous users, but disallow relaying and any other bad things on that port. And to leave the port 465 the way it is. As to my current configuration, I changed the master.cf file: smtps inet n - n - - smtpd and the main.cf file: # Use our SSL certificates smtpd_tls_cert_file = .....cer smtpd_tls_key_file = .....key smtpd_tls_security_level = may # Use Dovecot for SASL authentication smtpd_sasl_auth_enable = yes smtpd_sasl_security_options = noanonymous smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth broken_sasl_auth_clients = yes smtpd_recipient_restrictions = permit_sasl_authenticated, reject_unauth_destination Any help is appreciated!

• Is there way to enable 4 GB RAM in 32-bit Windows OS?

  - by Wahid Bitar

  I upgraded my PC to 4 GB RAM and I get only 3 GB. Windows 7 32-Bit consider that I've 4 GB RAM but didn't use more than 3 GB. Someone told me that MS Windows 32-bit doesn't support RAM larger than 3 GB. So please is there any way to make my OS "Windows 7 32-Bit" support more than 3 GB RAM ? *`Note: I can't move to 64-bit because I've many program doesn't work with a 64-bit OS. Edit:: I tried what Mr. Wonsungi advised me but whenever I check this option: Enable support for 4 GB of RAM I get the following error: 'Cannot access to the registry key HKEY_CLASSES_ROOT\CLSID\{E88DCCE0-11d1-A9F0-00AA0060FA31}.' There is no "CLSID" in my registry, I don't know why!.

• Opportunities in Cloud Computing

  - by Paul Sorensen

  A recent article from CIO Journal indicates that there is an extreme labor shortage (in certain technology areas) that is is leading to upward pressure on wages for IT Workers. This represents a great opportunity for those with certain skill-sets, among which include Java (Oracle certification is mentioned specifically). The article points out that a key driver of the labor shortage is the expansion of cloud computing. Cloud computing is set up to make life extremely simple for end-users, but the model pushes the complexity to back-end systems which are sophisticated, enterprise-level computing stacks (Oracle has an extensive set of cloud computing solutions). These complex systems require very highly-skilled IT professionals (the best-of-the-best) to successfully develop, implement, administer and maintain them. What this mean for you is that there is opportunity for those who have the appropriate skills at the appropriate levels. If you want to be a part of this opportunity you should do a self-assessment of your own skill-sets and experience. Based upon your results you can decide where it would be most appropriate to spend your time and resources for the highest return on your investment. By expanding and sharpening your skills and by gaining greater experience you will be better prepared to take advantage of career opportunities (like this) that come along periodically. As you evaluate your needs remember that Oracle University has a tremendous selection of high-quality eduction offerings (including training and certification) that can you help move your career forward. Thanks and best of luck!

• implementing dynamic query handler on historical data

  - by user2390183

  EDIT : Refined question to focus on the core issue Context: I have historical data about property (house) sales collected from various sources in a centralized/cloud data source (assume info collection is handled by a third party) Planning to develop an application to query and retrieve data from this centralized data source Example Queries: Simple : for given XYZ post code, what is average house price for 3 bed room house? Complex: What is estimated price for an house at "DD,Some Street,XYZ Post Code" (worked out from average values of historic data filtered by various characteristics of the house: house post code, no of bed rooms, total area, and other deeper insights like house building type, year of built, features)? In addition to average price, the application should support other property info ** maximum, or minimum price..etc and trend (graph) on a selected property attribute over a period of time**. Hence, the queries should not enforce the search based on a primary key or few fixed fields In other words, queries can be What is the change in 3 Bed Room house price (irrespective of location) over last 30 days? What kind of properties we can get for X price (irrespective of location or house type) The challenge I have is identifying the domain (BI/ Data Analytical or DB Design or DB Query Interface or DW related or something else) this problem (dynamic query on historic data) belong to, so that I can do further exploration My findings so far I could be wrong on the following, so please correct me if you think so I briefly read about BI/Data Analytics - I think it is heavy weight solution for my problem and has scalability issues. DB Design - As I understand RDBMS works well if you know Data model at design time. I am expecting attributes about property or other entity (user) that am going to bring in, would evolve quickly. hence maintenance would be an issue. As I am going to have multiple users executing query at same time, performance would be a bottleneck Other options like Graph DB (http://www.tinkerpop.com/) seems to be bit complex (they are good. but using those tools meant for generic purpose, make me think like assembly programming to solve my problem ) BigData related solution are to analyse data from multiple unrelated domains So, Any suggestion on the space this problem fit in ? (Especially if you have design/implementation experience of back-end for property listing or similar portals)

• Branding/Restricting a Software by License/Serial

  - by Sid

  I have made a POS System for a client of mine using MS Access Server-Client approach. He asked me to brand his software to allow only a certain "number" of users (cashiers) to access the POS System, and must be determined to the license his client will buy. EX: 10 User License = 10 Cashiers ( not necessarily 10 users, it can be 30 users, shifting) = it means 10 PCs will be installed with the client software I made. How and where do I put the logic that will determine if it is licensed or not. What I have done: I have created a serial key generator using Name. Problem is it can be duplicated once you give than name+serial combination, it would still work. I am counting the number of users logged at a time. This could be problematic as I am using MSAccess and not MSSQL. I have scrapped this idea, He also asked me if I could just put serial+mac address combination. That I could do but he will have a hard time implementing it and selling it if he needs the mac address of every computers to be installed with my POS. I am at lost on what can I do. Would like to ask for tips and suggestions. Thank you.

• MS-Outlook add-on to move a new message to the same folder as the rest of the thread

  - by Guss

  I'm forced to use MS-Outlook in my job, while I very much like the feature that shows all the messages of a discussion thread (that are stored in different folders) in the inbox when a new message is received for that thread, if the previous messages are in a different data file (which I'm forced to have as the MS-Exchange server quota is very very small) then the message list only shows the name of the data file and not the name of the folder where the messages are stored. As a result, because I file my message by context (i.e. all the emails for project A go into a "Project A" folder, etc), and its important for me to have all the messages in a single thread in the same folder, it is sometimes hard to figure out into which folder should I file the new message. It would be great help if there was some add-on or VBA script that I could add to my setup that will offer a shortcut key or a button to "file this message to the same folder as the previous messages in the conversation thread".

• Notification area balloon tip pop sound in Windows 7

  - by Worm Regards

  When I was using Windows XP, there was a distinct sound when an application showed a balloon tip in the notification area (aka system tray). Unfortunately, I didn't look any deeper into it. Now Windows 7 has this behavior disabled by default and I do not know how to configure it. Discovered the name of sound file used to accompany tray balloon tips in Windows XP Windows XP Balloon.wav More clues: interesting registry key is HKEY_USERS\XP Registry Hive\AppEvents\Schemes\Apps\.Default\SystemNotification\.Default Default value is %SystemRoot%\media\Windows XP Balloon.wav So, the System Notification event label appears to be correct, but tray balloons are silenced elsewhere.

• How to stop Word 2011 opening hyperlinks on click?

  - by John Yeates

  In previous versions of MS Word, there was a preference for the action to be taken when the user clicked a hyperlink: open it, or edit it. Word 2011 appears to have defaulted to opening the hyperlink, and I can't find the preference to change this behaviour. How can I change Word's default behaviour when a hyperlink is clicked to be editing the text of the hyperlink? Holding down a modifier key when clicking is not an acceptable solution, as the aim here is to prevent misclicks from causing web pages to open. Edit: the links need to stay as links in the saved document. But when clicked on my machine, they should not open; Word needs to default to just editing the link, so an inaccurate click does not take me out of the document into Safari. Older versions of Word had a preference controlling this, and Microsoft seem to have removed it and fixed the behaviour at the unsafe option in order to satisfy the point-and-drool crowd.

• How to generate new CSRs for TLS use in sendmail?

  - by Mikey B

  SendMail 8.13.8 | CentOS 5.x Hi Guys, I'm using ca-signed TLS certificates on my sendmail server and they are up for renewal soon. Our new CA doesn't like our old CSR so I need to generate a new CSR. Can someone point me to the procedure for doing this (without affecting the production certs that are already in use)? I'm paranoid of overwriting the old TLS certs in the process of generating a CSR. Most of the instructions I've found are for implementing self-signed TLS certs -- which isn't an option for me at this time. I'm thinking it would something like: openssl req -new -nodes -out new-tls.csr -keyout new-tls-private.key But I wasn't sure if I was missing some options there such as the -x509 option... -M

• Startech SVx41HDI Series Server Remote Control Usage Question - How do I switch away from a dead por

  - by tajh

  We have a Startech KVM over IP model SV841HDI and it was stuck pointing a port where the machine has been removed. We ended up having to physically plug something into that port in order to switch ports again, meaning that if someone in support accidentally switches to an empty port, we need to have a documented solution for making it useable again. The unit is old, no longer under warranty, firmware updates for it are no longer available (interestingly it runs a powerPC version of busybox). Since it does work well except for this one catch, we would like to avoid replacing it. Reading the manual, you have a several recommended methods. I tried them. Hit the left CTRL key a few times (as well as all the other popular KVM keys I could think of). The VNC GUI offers lots of buttons - none of them switch away from a dead port. The question is: how do I switch away from a dead port on this particular KVM remotely?

• License validation and calling home

  - by VitalyB

  I am developing an application that, when bought, can be activated using a license. Currently I am doing offline validation which is a bit troubling to me. I am aware there is nothing to do against cracks (i.e modified binaries), however, I am thinking to trying to discourage license-key pirating. Here is my current plan: When the user activates the software and after offline validation is successful, it tries to call home and validate the license. If home approves of the license or if home is unreachable, or if the user is offline, the license gets approved. If home is reached and tells the license is invalid, validation fails. Licensed application calls home the same way every time during startup (in background). If license is revoked (i.e pirated license or generated via keygen), the license get deactivated. This should help with piracy of licenses - An invalid license will be disabled and a valid license that was pirated can be revoked (and its legal owner supplied with new license). Pirate-users will be forced to use cracked version which are usually version specific and harder to reach. While it generally sounds good to me, I have some concerns: Users tend to not like home-calling and online validation. Would that kind of validation bother you? Even though in case of offline/failure the application stays licensed? It is clear that the whole scheme can be thwarted by going offline/firewall/etc. I think that the bother to do one of these is great enough to discourage casual license sharing, but I am not sure. As it goes in general with licensing and DRM variations, I am not sure the time I spend on that kind of protection isn't better spent by improving my product. I'd appreciate your input and thoughts. Thanks!

• Black screen after scheduled resume from sleep

  - by macbirdie

  I have a problem with my two Windows 7 setups at home. Whenever a scheduled task wakes up the machines from sleep, a black screen with a mouse cursor appears. If I move the mouse or press any key, desktop appears. The biggest problem is that during that black screen phase the display, sometimes even the PC too, doesn't go to stand by after a set period of time in power settings. If I get the desktop to show up, standby functions work fine. Display goes blank after a few minutes and as soon as the task doesn't need the PC, it goes back to sleep. It's frustrating that this "feature" is wasting energy and keeps lighting up the pc in the middle of the night for me to find it that way after I wake up. I found a handful of threads on the intertubes about the issue, but there were no answers in any of them. It sometimes happens in my XP machine at work as well.

• some keyboard keys not working properly

  - by surfmadpig

  I'm using windows 7. All of a sudden, a couple of hours ago, this happened: My keyboard number keys [above the letters] stopped working properly, both as numbers and as symbols. Only 5 and 6 are functional. Also, I've noticed that the End key isn't working either, and perhaps a couple more from that group. I'm pretty sure it has something to do with those evil Sticky Keys/Filter Keys/ whatever those ease of access things are, BUT I've turned off all the ease of access keyboard options and nothing has changed. Is it possible that something is still turned on while I unchecked it? Are the on/off checkboxes to control WHEN it happens or IF it happens? I also tried rebooting and uninstalling/reinstalling keyboard from device manager, to no avail. It's certainly a software issue and not a hardware issue, as I've tried another keyboard and the problem persists. And, predictably enough, it's annoying. Any ideas?

• error: no such partition after 11.10 upgrade to 12.04

  - by Alan King

  -I recently upgraded my 11.10 install to 12.04 LTS and got the above error message upon reboot after a GNU GRUB version ubuntu3 display showing Ubuntu 3.2.0-23-generic pae and other kernels or memory tests to choose from. The upgrade had to be done by CD because the Update Manager did not show the 12.04 upgrade option. After selecting the default install option of upgrading 11.10 to 12.04, I was presented with a screen saying that I had not specified a swap partition. Upon selection the 'back' key, I was taken to a partition page which listed two current partitions (only Ubuntu 11.10 had been installed - no Windoz): an ext4 partition plus a small 1.8GB partition. I double clicked the small partition and selected it as the swap partition even though I wondered at the time why this even came up. I can see the two user folders under home from the file manager screen while runnning 12.04 from the CD but if I try to access either one an error message is displayed saying I do not have permission while I get a loading message in the lower right corner of the window that does not go away. I have two questions: Can I access the user folders prior to recovery via the Terminal? If so, how? How do I fix the GRUB issue?

• No internet access on Windows 7 - part 2

  - by Vnuk

  This is a continuation of my previous question. The problems started when I turned on my wireless connection for the first time. Since then, every time I boot my Windows 7, my LAN connection does not have internet access. In my previous question, I got a key answer (route delete). Now my procedure to get LAN internet connectivity (local network works fine) when I boot looks like this: Power on WLAN Disconnect LAN cable Power off WLAN Execute route delete 0.0.0.0 if 11 Connect LAN cable Now my LAN connection has internet access. Another behavior that I can't explain - while my LAN connection has no internet access, Network and Sharing center refers to it as Unknown network, with a public icon. When I go through the fore mentioned procedure, it is referred to with my home WLAN network name, with status connected, and the Unknown network disappears.

• Enable 8th bit as Meta in zsh without a warning

  - by Bostonvaulter

  In my quest to configure my shell to work exactly how I want it with respect to the alt/meta key I am having some trouble. Recently I added "bindkey -m" to my .zshrc and now whenever I start a zsh shell (ie open a terminal window) I get this error "warning: `bindkey -m' disables multibyte support". Now since I don't care much about multibyte support atm, is there a way I can disable just this warning? Even better would be a way to use 8th-bit meta as well as multibyte. Also note that this happens on a clean zsh install on 4.3.9 and 4.3.10 My reasoning for wanting bindkey -m vim: alt mappings (my own personal commands/mappings) zsh: alt mappings (such as Alt-. to recall the last argument of the previous command) emacs: alt mappings (lots of built-ins) So, is there any way to disable this warning or otherwise accomplish what I'm trying to do?

• Can't open Control Panel or IE

  - by Josh

  I have a XP computer where when ever I try to open Control Panel nothing happens, nothing flashes on the screen. Same thing with Internet Explorer. I've scanned the computer with Malwarebytes and Avast, Malwaresbytes found some Adware which it removed without problems. Avast found nothing. I looked at the running processes with Process Explorer, nothing malicious running. And looked at a Process Monitor output when I tried to run IE, nothing obviously wrong. The process just decides to exit. What can I try next? I would suspect corrupt IE install but Control Panel doesn't work either. UPDATE: Nether work in Safe Mode under the user account. (only 1 user on the computer) But in Safe Mode, under the built in Administrator account, they work. So what ever is broken, is only broken in the one account. Anything under the HKCU registry key that could break this?

• nginx: override global ssl directives for specific servers

  - by alkar

  In my configuration I have placed the ssl_* directives inside the http block and have been using a wildcard certificate certified by a custom CA without any problems. However, I now want to use a new certificate for a new subdomain (a server), that has been certified by a recognized CA. Let's say the TLD is blah.org. I want my custom certificate with CN *.blah.org to be used on all domains except for new.blah.org that will use its own certificate/key pair of files with CN new.blah.org. How would one do that? Adding new ssl_* directives inside the server block doesn't seem to override the global settings.

• I installed ubuntu, the installer told me to reboot afterwards. I dd, and now linux wont boot

  - by mandy

  Im trying to dual boot between mac 10.6.8 and ubuntu 11.10. I have a macbook pro 8,1. So i installed from a 10.04 disk because the install window makes more sense to me, and it doesnt give me errors or anything. Also, any versions of ubuntu after that dont boot from disk for whatever reason. (i think its having to do with the efi boot thing. i have to get ubuntu 11.10 to boot from a usb with folders bootefiboot.iso) Then my plan after that was after the ubuntu 10.04 install took care of all the swap and stuff for me without being messy, to upgrade to 11.10. So here i have 10.04 booting successfully back and forth from mac osx no problem. I put in my 11.10 usb and the installer gives me the option to "update 10.04 to 11.10" bingo, jackpot, thats what i want. Everything proceeds as normal, as EVERY OTHER install of ubuntu i have ever done, then the installer finishes and says HEY! im finished! Continue testing or reboot now! So i reboot, and what do i get??? A black screen that says the file system isnt found, to enter a boot disk and press any key. WHAT THE HELL????? so i boot the 11.10 installer again from usb, and select "erase 11.10 and install 11.10", installer proceeds normally, and asks me to reboot. I reboot and get the SAME THING. Please, someone, help me get this right here. This is my first time actually dual booting between mac and linux. Usually i just wipe off osx completely and install ubuntu but i actually need to keep my mac partition this time. I have successfully installed 11.10 on this machine before, but that was when i did a clean install. Help?
