• Is there a way to combine multiple TextMate windows?

  - by yahelc

  After files have already been opened in separate windows, is there a way to combine them in TextMate 1.5.9? Or, is there a way to get CyberDuck to open group files edited at the same time as TextMate projects? If you open a folder of files in TextMate, it groups them all in one window like such: But, if I open multiple files separately (as my FTP forces), they appear in multiple windows. Is there any way to combine multiple TextMate windows into one, so they appear grouped like in the screenshot above?

• How to map a user to a domain, with Usermin and Postfix?

  - by HappyDeveloper

  What I need is to create a couple of websites, each one with only one user, which is allowed to send mails from any address @ his own domain. Example: Site foo.com would have an user foo, which can send mails from [email protected]. Currently, when the user logins to Usermin, the default 'from' field is example-dns.net (editable) I want it to show an editable field for the user part, and @foo.com (non editable) So how can I do this? Is there some way to automate this?

• lightweight access point?

  - by Joelio

  Im moving from an all in one to a router + access point. In doing googling and reasearch and talking to friends I ended up with router - cisco rv016 wifi access point - airnet 1142 lightweight access point. (lap1142n) In trying to set all this up and reading I think I bought the wrong access point. It seems I need a wireless controller? Can someone confirm that I should not have bought the lightweight one?

• How much did it cost our competitor to DDoS us at 50 Gbps for two weeks?

  - by MiniQuark

  I know that this question may sound like an invalid serverfault question, but I believe that it's quite valid: the amount of time and effort that a sysadmin should spend on DDoS protection is a direct function of typical DDoS prices. Let me rephrase this: protecting a web site against small attacks is one thing, but resisting 50 Gbps of UDP flood is another and requires time & money. Deciding whether or not to spend that time & money depends on whether such an attack is likely or not, and this in turn depends on how cheap and simple such an attack is for the attacker. So here's the full story: our company has been victim to a massive DDoS attack (over 50 Gbps of UDP traffic, full-time during 2 weeks). We are pretty sure that it's one of our competitors, and we actually know which one, because we were the only two remaining competitors on a very big request for proposal, and the DDoS attack magically stopped the day we won (double hurray, by the way)! These people have proved in the past that they are very dishonest, but we know that they are not technical at all, so we believe that they simply paid for some botnet DDoS service. I would like to know how much these services typically cost, for such a large scale attack. Please do not give any link to such services, I would really hate to give these people any publicity. I understand that a hacker could very well do this for free, but what's a typical price for such an attack if our competitors paid for it through some kind of botnet service? It is really starting to scare me (if we're talking thousands of dollars here, then I am really going to freak off: who knows, they might just hire a hit-man one day?). Of course we filed a complaint, but the police says that they cannot do much about it (DDoS attacks are virtually untraceable, so they say), and our suspicions are not enough to justify them raiding our competitor's offices to search for proofs. For your information, we now changed our infrastructure to be able to sustain such attacks: we now use a major CDN service so that our servers are not directly affected by DDoS attacks. Requests for dynamic pages do get proxied to our servers, but for low level attacks (UDP flood, or Syn floods, for example) we only receive legitimate trafic, so we're fine. If they decide to launch higher level attacks (HTTP flood or slowloris attacks for example), most of the load should be handled by the CDN... at least I hope so! Thank you very much for your help.

• What technologies allow bidirectional streaming of video?

  - by Roman

  Wikipedia says that Flash allows "bidirectional streaming of audio and video". Is it possible to do that with other technologies (for example with JavaScript)? In other words, I want to transfer video from one user of web-site to another one in real time. I want to have something that is already installed by many users or easy to install (Flash fulfills this requirements). And I want to have something free.

• Windows 7 Remote Desktop Connection Rendering Each Frame?

  - by TheDarkIn1978

  When connecting to my work computer over VPN and Remote Desktop Connection, images and videos are sent back one frame at a time, which really slows things down. I'm familiar with the "Experience" tab while connecting and the only options I have checked are "Visual styles" and "Persistent bitmap caching". Isn't it possible to work remotely that is more similar to screen sharing over Skype, where there is a lag but not every single frame has to be rendered and passed back to me one at a time? Both computers are running Windows 7 Professional.

• Creating zoom-pan video from a picture in Linux

  - by Pavel

  I would like to make a six second video using six images. Each second is sliding over one image from its top to its botom. Or some other motion effect – I would like to try several. I tried kdenlive Imagination Videoporama PhotoFilmStrip The first one has not enough settings (don't remember what exactly) and all those have rather poor quality – the resized picture is very "aliased" (like no quadratic filter was applied during resizing).

• Intermediate certificates on NLB load balanced servers

  - by MrVimes

  I am fairly sure I know how to install the 'main' certificate on load balanced servers (install on one, export, import to the others) but I'm not quite sure what to do about the intermediate certificate (the one you install using the certificates snap in in mmc) Do I manually install it using mmc on each server? or is there a similar process involved to the main cert (install, then export, then import on the others?)

• Duplicate mails in unread mail view of Windows Live Mail

  - by EpsilonVector

  When I get new mail and go to the "unread email" quick view I always see two version of the email, even though I definitely have only one such version in the inbox itself. Further, viewing the message via inbox usually marks only one of these copies as read, or sometimes none at all. I have no custom filters defined that could cause duplication. Any idea what's going on? PS This is the new version (2011).

• Preparing laptops for theft

  - by ccook

  With a number of laptops out there the likelihood of one being stolen is high. What methods, preferably free, can be used to secure the data on the computers? The laptops do not have any special hardware on them, and generally keep their user data in a dropbox folder. One small step taken is to have the the dropbox folder encrypted by Windows 7. Any additional suggestions are greatly appreciated. The data in the dropbox folder is sensitive.

• Insertion of rows without changing formulas on anohter sheets

  - by julie

  I have two separate spreadsheets which feed each other (one person completes the main one so all others autofill). I have set up formulas so it autofills but when I insert new lines into the main spreadsheet the other spreadsheet takes information from the wrong line, even though the new data was put in the place of the old data. (The new inserted lines were put in where the data was before). can anyone help me to "protect" the formulas from movement? I will appreciate any help.

  We have a CISCO hardware load balancer with two web servers behind it. We'd like to force some URLs to only be served by one of the machines. Firstly, is the job of the load balancer? or would a better approach be create a subdomain such as http://assets.example.com which would be automatically be routed to one of the servers?

• Why should I choose either PCL or PS when both are supported

  - by Goyuix

  Obviously the answer depends to some degree on the various versions supported, but in general terms - is there any reason I should pick one over the other? PCL for art and PS for text? Does one typically require less RAM on the printer? Speed differences? For home use it doesn't matter and only professional print people will notice and care?
