• price patterns drops

  - by doug

  I'm looking to buy a new laptop, and i don't need the top hi-tech because I'll use it for office type applications. In this case, the CPU and RAM are those who are mostly used. For example Intel i3 CPU was launched in Jan 2010 and in this case, the prices for Core Duo technology will drop. Do you know when or which are the signs? Can we talk about such a pattern?

• Differences between "apache"'s installations

  - by JustTrying

  Using Ubuntu 12.04, are there any differences between installing Apache httpd using sudo apt-get install apache2 (as the guide of Ubuntu says - https://help.ubuntu.com/12.04/serverguide/httpd.html ) or following the steps on the Apache documentation (http://httpd.apache.org/docs/2.4/install.html#overview)? I tried both ways; in the first case (using apt-get) the server seems to work - I open a browser page and I got it. In the second case I need other packages (apr, apr-util and pcre) and so I abandoned the attempt.

• Passive cooling a Pentium III

  - by gravyface

  Looking at running pfSense on an old P3 866Mhz. It's noisy, I'd like to passively-cool it, downclocking is ok as this is more than enough horsepower for my needs at home. Obviously I'm cheaping out here: wonder if I bigger heatsink will do and how much case flow I need (it's in a standard mid-tower ATX case).

• Capturing same interface with tshark with same or different capture filters

  - by Pankaj Goyal

  I am in stuck in a situation where an interface will be captured more than one time. Like :- $ tshark -i rpcap://1.1.1.1/lo -f "ip proto 1" -i rpcap://1.1.1.1/lo -f "ip proto 132" or (same filter) $ tshark -i rpcap://1.1.1.1/lo -f "ip proto 1" -i rpcap://1.1.1.1/lo -f "ip proto 1" what will happen in both the cases ? In first case, will the capture filter gets OR'ed or AND'ed ?? In second case, will the same packets be captured two times ?

• Experiences with Autonomy IDOL

  - by Joe Doyle

  We're currently looking at implementing Autonomy IDOL in our environment. Does anyone have any recommendations or gotchas that we should be aware of? Are other companies using IDOL successfully? I'm curious to get some real-world impressions beyond the case studies we've been provided with.

• How best to copy an SD card with corrupt filesystem to attempt recovery?

  - by pdbartlett

  I have an SD card with a corrupt filesystem, so wanted to clone it and attempt recovery on the copy (just in case of problems). I was thinking that dd-ing it Linux would be a sensible way to go, but don't really want to experiment in this situation. So if anyone has done this before then it would be good to know the exact approach that works. In case it helps, I have Ubuntu, OSX and Windows machines available. TIA, Paul.

• Having Textmate warn me when writing to a file that was modified since Textmate last read it

  - by emm

  Scenario: I open a file, I edit it. After I began editing, the file is modified by another program. Finally, I save the file. In that case, Vim would provide that helpful warning: WARNING: The file has been changed since reading it Do you really want to write to it (y/n)? But Textmate will overwrite the file silently, which can result in unpleasant data loss (in my case, a de facto revert on Git). How can I prevent that?

• how to convert all to lowercase user names in Active directory

  - by Albert Widjaja

  I am trying to get our subversion configuration management repository to work with active directory. At the moment I am having a problem with some users having mixed case user names in active directory. Would it be possible to change all users with mixed case user names to be all lowercase instead? I'm using Windows Server 2003 Active Directory with 64 bit domain controller running on Windows 2000 mixed functionality.

• Does putting the XFS log on an SSD significantly improve performance?

  - by Paul Wagland

  I have a five disk array running XFS in RAID5, and I would like to improve it's performance. I have seen some hints that putting the log onto a separate device can help, does putting the log onto an SSD help dramtically? In theory, it should, but I have not been able to find any case studies where someone has actually done this, and buying an SSD and then having it not work well would be inconvenient at best…

• Why does hardware get slower with time?

  - by Alexey Kulikov

  Why does hardware get slower with time? I have been a PC owner since 1990 and every computer I have had in my life became really, really slow after 3-4 years (even with a full system-reinstall). It is the case with Windows PCs. It is also the case with Apple Hardware. Why is this happening? Can this be avoided?

• How do I get Outlook to auto fill information

  - by Mykroft

  I repeatedly have to send emails that are nearly identical except they have a different case number. I'd like to setup outlook to just ask me for the case number, fill it in the appropriate place in the body and subject of the email and then send it to a preset list of recipients (it's a static list of people). I think some combination of Forms and Templates should be able to do this but I'm unsure how.

• Sendmail is not ignoring MX lookups

  - by daniel

  Hello, I recently learned of the joys of square brackets with SMART_HOST to have sendmail ignore MX lookups. I need this functionality, however, I can't seem to make it persistant. Sending mail with -Am works, however, -bm does not. In the -Am case, the correct mail server is used. In the -bm case, an MX lookup is still being performed. Is there a way to disable MX lookups (or some working alternative)? Thanks

  Is there some kind of software/driver that would enable me to create one big volume out of several hard disks but retain the file structure on each HD? This would be in case where one hard disk crashes and only data on that HD will be lost. Windows 7 enables me to do that but in case one HD breaks all data will be lost.

• Zenoss: Getting SNMP stats over SSH

  - by normalocity

  I have the SSH connection working. I have it successfully modeling the device (Ubuntu Server, in this case). What I can't get to work is the SNMP portion. It sounds like I have to custom add the snmpwalk command when doing monitoring over SSH - in other words, have Zenoss connect via SSH, and then run an arbitrary command agains the client (in this case, an snmpwalk), and then parse the results. What I need help doing is: Add the snmpwalk command to the SSH monitoring Parsing the output and getting the data back into the charts

• What might cause the Save and Open dialog windows to just not work?

  - by Nick Bolton

  In several applications, the Save and Load dialog windows are just not showing. And in notepad (which obviously handles the return code) is reporting an out of memory issue, which I'm sure is not the case; I think it's assuming it's out of memory as it can't get the window handle. In any case, there's something definitely wrong with Windows, but there's nothing in the event log. Any idea why this might happen?

• Moving Temp folder location

  - by Chadworthington

  My C drive is a small SSD that I don't want to wear out or fill with unnecessary stuff. Is there any harm in moving the temp folder to another drive? I am under the impression that Windows will not need to look for files here, for example, in the case of uninstalls... Is this the case?

• Can I extend my monitors, mouse, keyboard accross a room?

  - by jasondavis

  I am considering building my next PC into a server rack case, the reason is I am getting a server cabinet and will be putting in a few servers in it. It will be in my room where I use my main PC as well and in my case it just makes sense to build my next PC into this cabinet/rack. So my main concern, will I be able to extend my mouse, keyboard, and 2-3 monitors10-15 feet accross a room from my server rack to my desk?

• Trunking at Router Port

  - by singh

  After reading a bit about interVLAN routing got a doubt regarding how trunking takes place at router and at switch.In case of switch we configure a port interface as trunk port and say all vlan's are allowed here but in case of router we configure sub interface as trunk saying particular vlan belongs to particular subinterface .Can't we configure only a single port interface on router just like Switch and say all vlan's are allowed here on this interface ,why to go for sub interfaces? Hope I'm able to put my question in right way.

• Secure Standalone Server Plus Firewall Unit [closed]

  - by orbitron

  We need to send a 2U server, 1U UPS and 1U firewall to a third-party. The thing is, it needs to be a secured case (locked unit) that has proper airflow and we can have power and networking cables coming out of the back. We've googled far and wide and have only been able to find 'hard case' units that offer some level of security but they are extremely bulky and require freight delivery. Thank you for any insight or solutions.

• IE8 Jquery Javascript "Error: Object required" Bug

  - by thechrisvoth

  IE8 throws an "Error: Object required" message (error in the actual jquery library script, not my javascript file) when the switch statement in this function runs. This code works in IE6, IE7, FF3, and Safari... Any ideas? Does it have something to do with the '$(this)' selector in the switch? Thanks! function totshirts(){ $('.shirt-totals input').val('0'); var cxs = 0; var cs = 0; var cm = 0; $.each($('select.size'), function() { switch($(this).val()){ case "cxs": cxs ++; $('input[name="cxs"]').val(cxs); break; case "cs": cs ++; $('input[name="cs"]').val(cs); break; case "cm": cm ++; $('input[name="cm"]').val(cm); break; } }); }

• Exclude a directory from a rewriterule using ISAPI rewrite 3

  - by mludd

  Basically I've recently added the below rule in my httpd.conf for ISAPI rewrite on an IIS server to make sure that it always defaults to lower-case file and directory names. RewriteRule ^(.*[A-Z].*)$ $1 [CL,R=301,L] This is all fine and dandy for every part of the site except for one directory which we can call /MisbehavingDir, the code in this particular directory is filled with mixed-case filenames and lots of server- and client-side scripting that would have to be rewritten to use all lower-case in order to work properly (with the RewriteRule above it seems to hit a couple of 301s in the wrong places which causes that part of the site to function poorly to say the least). Since I'm not in the mood for rewriting that part of the site I'd love to find a good way to modify the above regex so that it matches everything except paths starting with MisbehavingDir and since my regex-fu isn't really good enough I figured I'd ask here. Is there a simple "beautiful" solution to this that anyone wants to share or should I just set aside several days to rewrite the app, then test it and go through that whole dance?

• DBD::CSV: How can I generate different behavior with the two f_ext-options ".csv" and ".csv/r"?

  - by sid_com

  This is from the DBD::File-documentation: f_ext This attribute is used for setting the file extension where (CSV) files are opened. There are several possibilities. DBI:CSV:f_dir=data;f_ext=.csv In this case, DBD::File will open only table.csv if both table.csv and table exist in the datadir. The table will still be named table. If your datadir has files with extensions, and you do not pass this attribute, your table is named table.csv, which is probably not what you wanted. The extension is always case-insensitive. The table names are not. DBI:CSV:f_dir=data;f_ext=.csv/r In this case the extension is required, and all filenames that do not match are ignored. It was not possible for me to generate different behavior with the two options ".csv/r" and ".csv". Could someone show me an example, where I can see the difference between ".csv/r" and ".csv"?

• Linq to Entities : using ToLower() on NText fields

  - by Julien N

  I'm using SQL Server 2005, with a case sensitive database.. In a search function, I need to create a Linq To Entities (L2E) query with a "where" clause that compare several strings with the data in the database with these rules : The comparison is a "Contains" mode, not strict compare : easy as the string's Contains() method is allowed in L2E The comparison must be case insensitive : I use ToLower() on both elements to perform an insensitive comparison. All of this performs really well but I ran into the following Exception : "Argument data type ntext is invalid for argument 1 of lower function" on one of my fields. It seems that the field is a NText field and I can't perform a ToLower() on that. What could I do to be able to perform a case insensitive Contains() on that NText field ?
