  • FreeNas running on ESXi - sometimes gets very slugish.

    - by Luma
    Hello everyone, I have a ESXi server (dual quad core, 8GB of DDR3 ram, 6x 1TB WD Blacks running in RAid 5 on the PErc 6/i controller. I have a 64bit freenas VM running, on this VM I keep about 200Gigs of stuff that my windows machines access. every now and then the throughput of this VM just dies, for example right now it can't even handle streaming a song and when I tried to transfer a folder the speed goes from 10-400KB/s. Might I add at this point that the ESXi box has dual gigabit network cards plugged into a good solid gigabit switch and other linux and windows VM's are just fine I have seen speeds over 90MB/s (frequently) The server still has ram left over (plenty actually) and cpu is very low (500-1000mhz) any ideas what could cause this? thanks. Luc

  • Dual pane file manager for Mac OS X

    - by Alex Kaushovik
    Is there a good customizable dual-pane file manager for Mac like Total Commander / Far Manager in Windows, or like Krusader / Midnight Commander in Linux? I used to work on Windows for quite a while and mostly used Far Manager and sometimes Total Commander, then I switched to Ubuntu Linux and used Krusader, now I switched to Mac OS (Snow Leopard) and I'm having a hard time trying to find a good file manager... Many of the existing applications are trying to replace the Finder with "multimedia capabilities nobody cares about in file manager - IMHO" (Path Finder, ForkLift), some of them are almost good dual-pane file managers (couldn't remember examples), but none of them worked for me mostly because of one reason: I couldn't integrate my file/folder comparison utility (Araxis Merge for Mac) with them... The way it worked for me in Windows and Linux is that I was setting the cursor on one file in the left pane, then setting the right-pane cursor on another file in right pane, then I pressed a hotkey that launched Araxis Merge with those to files/folders comparison results. It was very easy to set up in Far Manager (Windows) and Krusader (Linux, actually in Linux I used "Meld" instead of Araxis Merge...) The tool I'm looking for doesn't necessarily has to be free... Thank you!

  • SSMS Tools Pack 2.1.0 is out. Added support for SQL Server 2012 RC0.

    - by Mladen Prajdic
    This version adds support for SQL Server 2012 RC0 and fixes a few bugs with SQL History. Because of the support for regions in SSMS 2012 the regions and debug sections feature has been removed from SSMS Tools Pack for SQL Server 2012. The feature is still available for previous SSMS versions. In other news SSMS Tools Pack has won the SQL Magazine bronze award for best free tool of 2011. You can view all the details at the SQL Server Magazine Award page. Thanx to all the people who voted for it. I'm glad you all like it and use it with great success. Also I've added a possibility for you to subscribe to email notifications in case the auto-updater doesn't work for you for some reason like being behind a proxy. Enjoy it!

  • How to handle interruptions in developer work without losing concentration? [closed]

    - by tomaszs
    I work as a developer for some years now. Mainly the issue why it's antisocial work is because you need to spend much time programming. I've been always the kind of developer who likes to cut off from any sources of distraction and spend several hours on project because in this way i (as i hope) do it faster. There are also other kinds of developers, more social that can chat, read, watch movies while development and they are ok with this and don't hesitate to be interrupted in their work in any time and come back to the project without any problem. For me any distraction is source of frustration because i need to spend substantial time to load my mind with all info about the project and to concentrate back on the tasks. I always thought it's better to do this that way because project is completed faster. But it makes some things difficult: it's hard to chat with someone who needs to have some important info: because you are a bit frustrated when you know you loose your Zen. And sometimes its more important to chat with someone than to loose Zen. Well.. mostly in any other kind of work the ability to be "multitask" is very important. But as a developer and as a person it's also very important to stay social. And i see now that the problem of concentration makes it difficult to make the right chose: the cost of maintaining concentration is just sometimes so damn high! So is it only me that i have so little concentration skills so any interruption is for me a big deal? Maybe it's just i have so bad memory so that i dont remember all issues of a project so long? Or maybe i develop the project in a fashion that requires me to store so much info on my mind only to be able to start working with code? Or should i just accept that being more social will make me finish project slower and in the fashion that i personally consider non 100% productive? And it's just normal thing and i should just accept it and start to live like any other person who has many works and don't assume that programming is in any case other than any other work and i just do fuzz about the whole concentration thing? This is question for mid-pro developers. I think you was having the same dillema in your life. I would be glad if you could help me take the right road here because it's just driving me and i suppose people i work with crazy for years.

  • How to switch from developer to dba? [on hold]

    - by lamwaiman1988
    I am working as a developer for 3 years and I am thinking of switch to dba. I do not own any certificate nor received any training regarding the daily job of dba. My company also do not offer any chance of work/training related to a dba. If I want to be a dba ( because of the salary and a much stable job than developer ), should I go to get some oracle certificates? I've also heard that you can't be a good dba if you cannot get a good understanding about the working OS such as windows/unix ( and to do that you also need to get some certificate on windows administration or unix administration ) but they recommend book of Rich Stevens over certificate. I am confused on what should I do to make this happen.

  • What is the increase in developer productivity while using Hibernate?

    - by Tarun Kohli
    I was curious to find out the percentage increase in developer's productivity by using Hibernate. We use both Hibernate and NHibernate extensively and find them to be extremely elegant frameworks but haven't undertaken any study to find out the time savings by using them. IMHO, one could get a good 30 to 40% jump in developer productivity as one doesn't have to write the basic CRUD operations and bother about caching. But, are there are any formal case studies which prove that point? I would really appreciate if someone could direct me to a published white paper about some statistics about the productivity gains.

  • What would the ultimate developer training class look like?

    - by user652273
    I think today's typical/traditional 3-5 days developer training classes aren't so great, as you tend to forget half of it shortly after. It's too much one way communication and not enough interaction. Also brain research has shown that this kind of setup is usually not optimal for efficient learning. For clarification, I am referring to professional, commercial, paid classes. However this could also be applied for any kind of studies. How could the ultimate developer training package be setup to really make sure you learn what you are supposed to learn? Would that be more: Multimedia? Exercises? Homeworks? Spread out over time instead of 3-5 compact days? Group projects?

  • What is a good third-party SMTP software for custom logging?

    - by Lorcan O'Neill
    I am currently using IIS 6 SMTP to send out some of our mail and I unfortunately amn't finding the logging performed by it to be verbose enough - nor am I able to customise it to the level I would find verbose enough. I'm wondering if anyone can recommend a piece of third-party SMTP software which would allow for customisability of the logging down to the point where I can inject in my own columns or perform regular expressions on the outgoing message data or headers.

  • Is there a version of Emacs thats runs exactly the same on OSX, Windows and Linux?

    - by Zubair
    I'm using Emacs on different environments and unsure of which version to use so that they all behave the same as I hear there are differences between XEamcs, Emacs, and some other versions. Which should I use? By the way, I am not looking to start a flame war with this post, I just want a version of emacs that runs the same everywhere which is the whole point of me wanting to switch to emacs.

  • Fast extraction of a time range from syslog logfile?

    - by mike
    I've got a logfile in the standard syslog format. It looks like this, except with hundreds of lines per second: Jan 11 07:48:46 blahblahblah... Jan 11 07:49:00 blahblahblah... Jan 11 07:50:13 blahblahblah... Jan 11 07:51:22 blahblahblah... Jan 11 07:58:04 blahblahblah... It doesn't roll at exactly midnight, but it'll never have more than two days in it. I often have to extract a timeslice from this file. I'd like to write a general-purpose script for this, that I can call like: $ timegrep 22:30-02:00 /logs/something.log ...and have it pull out the lines from 22:30, onward across the midnight boundary, until 2am the next day. There are a few caveats: I don't want to have to bother typing the date(s) on the command line, just the times. The program should be smart enough to figure them out. The log date format doesn't include the year, so it should guess based on the current year, but nonetheless do the right thing around New Year's Day. I want it to be fast -- it should use the fact that the lines are in order to seek around in the file and use a binary search. Before I spend a bunch of time writing this, does it already exist?

  • Third-party Information Screen Opening Blank

    - by Jacob
    I'm working with a client who is trying to use our software, which accesses information (sends & receives) from a third-party website. When this client tries to access these pages, a window opens, as expected, but is completely blank and no error message is received. This is the first time I've seen this with many other clients successfully using this product, which leads me to believe that it has something to do with the settings on the computer somewhere, but cannot figure out what might be happening. Windows Server 2003 R2, Standard Edition, Service Pack 2. Firewall is already off. Tried AVG on & temporarily disabled.

  • Failed to start up after upgrading software in ubuntu 10.10

    - by Landy
    I've been running Ubuntu 10.10 in a physical x86-64 machine. Today Update Manager reminded me that there are some updates to install and I confirmed the action. I should had read the update list but I didn't. I can only remember there is an update about cups. After the upgrading, Update Manager requires a restart and I confirmed too. But after the restart, the computer can't start up. There are errors in the console. Begin: Running /scripts/init-premount ... done. Begin: Mounting root file system ...

  • Command-line tool to deduplicate a single humongous file?

    - by romkyns
    I make regular snapshots of my VM using a nightly script. These backups are compressed using WinRAR and do shrink considerably, but I suspect it's not as efficient as had the file had been deduplicated first (just a hunch which I'm hoping to test). So instead of compressing the VHD itself, I would like to deduplicate the single file first, and then compress the output of the deduplicator. Is anyone aware of such a CLI tool?

  • Copy filename to clipboard

    - by Charles Roper
    I am looking for a Windows utility that can copy the currently selected filename, including the path, to the clipboard, ideally through the right-click menu. Some degree of flexibility would be useful, like the ability to copy just the filename, path+filename, filename minus extension, etc. This isn't essential, though, as long as it can copy the path+filename. Must be compatible with XP, Vista and Win7. Free and/or open source would be ideal. Thanks!

  • Discovering proxy servers on a private network

    - by AIB
    Suppose that I am in a private network of computers (say each having ip addresses 192.168.. ). Some of the machines( we have no information regarding their ip, name and no physical access to the servers) in the network are connected to internet and they run an http proxy at some port say 3128. Is there a program which can be run on Windows or Linux which will give me the list of machines(ip addresses and ports if possible) acting as proxy servers?

  • How to repeat a POST request using Chrome's developer tools?

    - by Luke The Obscure
    Not sure if this is the right stack exchange to ask this, but here goes... I'm trying to wean myself off of Firebug, which has served me very well for a lot of years. One feature that seems to be missing in Chrome's dev tools is the ability to repeat an AJAX POST. In firebug I can right click on the request in the console and hit "Open in new tab" and the request is repeated exactly as it was originally sent. In Chrome, the same action just does a normal GET on the link, without any of the post data. Is there any way to repeat an AJAX POST in Chrome's dev tools?

  • How to see the properties of a DOM element as they change in realtime?

    - by allquixotic
    JavaScript code can update the properties/attributes of DOM elements in real time by responding to events and so on. Here is an example. In the table on that page, move your mouse over the cells. Notice how they change color when the mouse is on them, and the color goes away when you move the mouse to another cell. Now, using Firefox or Chrome (but not IE, Opera, etc.), I want to examine the background color, expressed in RGB or hex or whatever, of the cells updated in real time, as the mouse cursor enters and leaves the region and causes the JS to do its thing. The behavior that I observe, currently, is that the Inspect Element functionality of both Firefox and Chrome does not update the value of the properties as they are updated by JavaScript. So, in order to view the latest value of the property, I have to inspect the element again, and it takes a momentary "snapshot" of the values. But since the values only change while I have the mouse on them, I can't take a snapshot of the value I want while my mouse cursor is over the cell, because I have to remove my mouse from the cell to select the "Inspect Element" item in the right-click list! If it is possible to have the values updated in real time using either Firefox or Chrome, or an extension, on any recent version of the software (up to the latest stable), please provide instructions for doing so.
