• rsync server side limit bandwidth/connection

  - by c2h2

  In a VOIP application, I have upto 3000 clients rsync audio files from there linux server in a daily, server is placed at a data center (10Mbps in/out bound), the server works as a VOIP sip server running FreeSWITCH (low ping latency should be ensured.) Therefore I would like to have server side control of rsync which controls: Limit total outbound bandwidth. Limit total number of connections. (Reject clients while at max number of connection and let it retry after a specific time frame.) OPTIONAL: list/kill individual connections. Normally I would use ssh + rsync + pem_keys with some extra options, but above requirements are not feasible by simple command lines. Can anyone point me some direction. or show some scripts/tools? I would also probably integrate them and release on github. Thanks!

• Application to handle form approval

  - by ChrisMuench

  Hello, Hopefully this is the right place for this question. I have done a fair amount of research and yet to find anything that matches what I want. What I'm envisioning is the following. Let me know if any of you know of a program that will do what I want. Also it must be web-based anom user - fills out form - email gets sent to admin saying xyz has filled out form abc with links to approve/disapprove request. admin can also login and edit form and resent results to original submitter. Also once the admin approves/disapproves request the original submitter gets an approve/disapprove email. and you can search by date submitted, specific project/form, status of request(submitted, approved, disapproved). any ideas all on where I could find this? I started to look into drupal with workflows and actions but it just doesn't flow right for this

• Win 2008 Server configuration

  - by user123790

  Let me preface my question by saying I'm a novice in regards to server configuration. It's been 12+ years since I've attempted this. What we (our small office) are trying to achieve is to setup a Win 2008 server (located in a home) in a home network configuration (basic wireless router w/DHCP) that we (the office) can VPN to from our office. I have installed the software, installed DHCP, removed DHCP from the router, set the scope for 100 IPs and am now looking for information as to where I go from here? I believe I need to configure DNS and possibly set up static routes on the router for the home devices that need internet? The wireless clients are not receiving IPs is the current issue that I'd like to tackle. Also, would it be feasible to use the router's DHCP to assign IPs rather than having the server do it? If so, what would be the most direct way to accomplish this? I appreciate any help in this matter. Thanks

• Differentiating between user script input formats

  - by KChaloux

  I have a .NET project at work that provides a couple of (Iron)Python scripts to the customers, to allow them to customize the output of the program. The application generates code for certain machines, and supports a couple of different formats. Until recently, we only provided a script for one format. We're expanding upon that to include support for the others. If the user is using a script, they select their input script before generating the output code. A script designed for Format1 output is going to cause errors if they're trying to generate Format2 output. I need to deal with this. One option would just be to let the customers use common sense, and if they load the wrong script it will just fail, or worse, produce inaccurate data. I'm inclined to provide a little more protection than that. At the moment I'm considering putting a shebang-style comment line at the top of the script, ala: # OUTPUT - Format1 If the user tries to run a Format2 process with a Format1 script, it will warn them. Alternatively I could create different file extensions for the input scripts that vary by type. The file-type comment approach helps prevent the script from actually loading improperly, at the cost of failing to warn the user until they've already selected it, via a dialog box. Using different file extensions would allow me to cut down on visual clutter when providing a File Dialog, but doesn't actually stop them from loading the wrong script. So I'm really not sure if the right approach is to just leave it alone, or provide some safeguards.

• What naming pattern can I use for sequential file naming (photos) when only their relative sequence is known?

  - by Juhele

  I got some old scanned photos and I want to put them in correct order. Unfortunately, I have no possibility to find out the exact order, only relative one like: "hm, this photo was surely taken after this one" and organize them step-by-step by manually changing numbering again and again. Is there any program (best free or opensource), where could I interactively put the photo in correct order straightaway (maybe by changing the order by dragging with mouse) and finally apply some file renaming to keep the file order? thank you in advance PS: running Windows (XP and 7), but if you know something for linux, let me kno too, please

• Permission issue when deleting folders

  - by nate

  I can't delete some folders and some actions are being denied because I do not have administrator access. But in my user account it says i am an administrator. I also just upgraded from Windows Vista 64-bit to Windows 7 64-bit, but I had this problem before upgrading, but now I am being denied more things. I also can't reorder the way files are sorted in folders. I can sort them through the default means, but I literally can't drag and drop them if I want to reorder them. I don't know if this is another problem or if it is related. Let me know if you need more information. Thanks!

• how to store and retrieve/generate UI?

  - by thindery

  I'm working on a site that will have hundreds, and eventually thousands, of paper products that users can customize online. Here is a very simple sample of what needs to be generated based on the product id: demo. This is a very simple version. I plan on replacing text fields with prettier elements(like the slider on tab 3). I imagine most of this can be achieved via jquery. So basically a product will have multiple pages(tabs), with multiple form elements on each page. I've never done a large scale project like this before and I am looking for ideas/suggestions for how I can store the info for each product that needs to be generated to create the UI. For each product, I need to store how many pages there are, what form fields are on each page, and the order of the fields on the page. As well as setting default text values and form options(font size, etc). Then with all this info stored somewhere, I can have the web app retrieve it and generate the UI with text fields, sliders, and other jquery-ish form enhancements, for that particular product. Can anyone toss out some suggestions, links, blogs, tutorials? I'm not really sure where to begin with this or what I need to start to investigate. I have experience with php, mysql, javascript, jquery, html, css, and that is really about it. I'm open to learning(and would enjoy exploring) new frameworks, programming, etc that will really get this web app working correctly, efficiently, and effectively. Maybe I should start looking into a mvc framework? like i said, i really have no idea what is the best approach. please let me know your suggestions!

• Battery notification always showing 'xx% remaining' with Windows 7 on an acer Aspire 5590

  - by dindeman

  My battery level always shows up as something like 55% remaining or 63% remaining ...etc despite that it is in fact charging. Additionally it doesn't go any further than 80% remaining even if I keep it in charge forever. This leads me to a side annoying effect which is that I cannot proceed to install Windows 7 Service Pack 1 as its installer requires the laptop to be plugged with a power cord. My laptop is plugged with the power cord but because of the above issue (it doesn't display anything else than the xx% remaining) Windows thinks that the laptop is using its battery and that the power cord is disconnected. I have installed the original acer ePower Management tool that let you configure the power scheme... etc, I was hoping that this would help me circumvent the 80% issue but it doesn't.

• Java EE 7 Survey Results!

  - by reza_rahman

  As you know, the Java EE 7 EG recently posted a survey to gather broad community feedback on a number of critical open issues. For reference, you can find the original survey here. Over 1,100 developers took time out of their busy lives to let their voices be heard! The results were just posted to the Java EE EG. The exact summary sent to the EG is available here. We would like to take this opportunity to thank each and every one the individuals who took the survey. It is very appreciated, encouraging and worth it's weight in gold. In particular, I tried to capture just some of the high-quality, intelligent, thoughtful and professional comments in the summary to the EG. I highly encourage you to continue to stay involved, perhaps through the Adopt-a-JSR program. We would also like to sincerely thank java.net, JavaLobby, TSS and InfoQ for helping spread the word about the survey. In addition, many thanks to independent Java EE 7 expert group member Markus Eisele for blogging the results. You can read more details about the results here.

• How do I implement deceleration for the player character?

  - by tesselode

  Using delta time with addition and subtraction is easy. player.speed += 100 * dt However, multiplication and division complicate things a bit. For example, let's say I want the player to double his speed every second. player.speed = player.speed * 2 * dt I can't do this because it'll slow down the player (unless delta time is really high). Division is the same way, except it'll speed things way up. How can I handle multiplication and division with delta time? Edit: it looks like my question has confused everyone. I really just wanted to be able to implement deceleration without this horrible mass of code: else if speed > 0 then speed = speed - 20 * dt if speed < 0 then speed = 0 end end if speed < 0 then speed = speed + 20 * dt if speed > 0 then speed = 0 end end end Because that's way bigger than it needs to be. So far a better solution seems to be: speed = speed - speed * whatever_number * dt

• Using VMware's ESXi, can I plug in 30 USB Wireless adapters and allow each of 30 VMs one?

  - by 31eee384

  I'm assuming ESXi will act very similarly to VMware Workstation or other products, so answers based on knowledge of those programs might also help. I want to plug in 30 USB Wireless or Ethernet adapters into my server, and let each VM access one and only one of these devices. Unfortunately, I don't have the hardware to just try it out as the purchase of hubs and adapters hinges on the result of this question. The answer could be a resounding "yes, easy!" and that would be great. I couldn't find any answers to this question with google, and it's possible that this is because it's so easy to do. Thanks!

• Boot Camp: is it possible to restart directly to Windows from Mac OS X?

  - by Jonik

  With the Boot Camp tools installed on Windows, there's an option for rebooting directly to Mac OS ("Restart in Mac OS X" from Boot Camp system tray item). But is this possible in the opposite direction? In other words, instead of the procedure 1) "Restart", 2) wait for OS X to shut down, 3) hold Option key (?), and 4) select the Windows partition, can I tell my Mac to restart so that Windows is selected on the next boot? Something like "Restart in Windows" which would let me bypass steps 2-4. NB: I want to keep Mac OS X as the default OS; I'm just looking for a convenient shortcut when normally running OS X and occasionally wanting to boot to Windows.

• SharePoint 2013 Licensing Simplified

  - by Sahil Malik

  SharePoint 2010 Training: more information Before I begin, let me preface this by saying, I don't work for Microsoft, I don't sell SharePoint, this is merely my understanding of the SharePoint 2013 licensing model. As always, before making any money decisions based on the below, talk to your Microsoft rep. The below is just my understanding, you are responsible for any decision you may take. With that aside, here is how I understand SharePoint 2013 licensing. Note that everything below is for on-prem SharePoint only. Also it goes without saying that you need to purchase windows server and SQL server licenses etc. on top of what you read below. The Basics. You need to buy two things - the SharePoint server, and CALs. SharePoint server comes in SharePoint foundation, standard and enterprise. CALs can be either enterprise or standard, and they can be bought as CALs for SharePoint or a CAL suite which includes exchange and lync. CALs can also be purchased and user CAL or device CAL.

• Working as a contractor--questions part II

  - by universe_hacker

  This is a follow-up to this discussion: Working as a contractor--questions I still would like to get more info on the following points, when working as a contractor as opposed to direct employee: Housing: for short-term contracts (let's say 6 months or less) that are not in your home area, where and how do you search for short-term, flexible housing? Especially since an employer would typically want you to start immediately, so you don't have the time to go out and explore. Also, would you typically look for furnished apartments because the cost transporting your own furniture for a few months is not justified? Work hours and pay: are contractors more strictly supervised (as far as getting specified work done) because they get paid by the hour? There are also supposed to get overtime pay (at a higher rate) if they work more than 40 hours per week, does this really happen? Or do they work unpaid extra hours just like many regular employees? Some potential employers have mentioned paying the "per diem", which is essentially a non-taxable daily allowance, which is supposed to be used for living expenses. This money gets subtracted from you per-hour rate, but the advantage is that you pay less tax. However, from the information I have seen, the per diem can only be paid if you maintain a "permanent" residence you intend to return to. Is this checked in practice, and if yes, how?

• Sign out of messenger on Windows 8

  - by jmlumpkin

  I just installed the Windows 8 Consumer Preview. Just going through the default procedure, I let it use my Xbox Live account to create a user. When I then went and turned on my Xbox, it now notified me that I was logged into Messenger in two locations. I went back to Windows 8, and turned my Live account into a local account on that machine. But when I then turned the Xbox again, I got the same message. Is there a way to just 'sign out of messenger' on Windows 8? Or is there a location to even see where I am signed in at?

• Running a webserver behind a firewall, is it secure?

  - by i.am.intern

  Currently we have a Linux-based firewall which NAT-ing our public IP address to give internet access to our staff's PCs and a Windows Server 2003 for internal filesharing. I want to host Redmine/SVN (a bugtracker) internally behind this firewall using a Linux server. This webserver will be accessed by our clients externally so they can post bug reports. This means that I have to open port 80 & 22 at the firewall to give access to the webserver and me to SSH it from home. However, let's say I'm using password-based SSH for the webserver and somebody cracked it. Does that mean the cracker could ping and access other servers and PCs in the network?

• Data loss with roaming profiles on login on two different computers

  - by Jurriaan Pijpers

  We have a Windows server 2003 system with Active Directory and all of our users have roaming profiles. One of the users let someone login with his username and password on a different computer (2) while he was working on his own computer (1). Now when this user logs in on his own computer (1), the profile that is loaded is one that dates back many months (i think from the last time he logged on to computer 2). My suspicion is that the profile that was cached on computer 2 from many months back when this user last logged on on this computer, on logoff, synced over the newer profile on the server. so that now when he logs in, he gets this old profile. Now my questions: Is it possible to retrieve te newer profile? Is it possible to keep this from happening in the future?

• Updating, etc., automatically

  - by Steve D

  Is there a way to set up Ubuntu 12.04 (or earlier versions) so that all recommended updates are done automatically, say once a week? When I say automatically, I mean no password entry or user intervention required. This sounds like a stupid request, so let me tell why I'm asking. My grandfather knows nothing about computers; he uses his solely to read Yahoo! mail. I want to get rid of his clunky, spyware-ridden Windows XP and install Ubuntu. I want to set it up so when he turns the computer on, after a couple minutes, voila!, Yahoo! mail, already signed in, ready to go. The problem is I don't want to have to go over there every week or so and make sure everything is up-to-date, he hasn't accidentally installed any spyware, etc. So can this be done? Is this the best way to set things up for my grandfather? Are there other things I should be worried about when it comes to keeping things hassle-free for him? Please don't post anything like "why not teach him how to... blah blah blah". My grandfather is 80 years old and has made it clear email is the only thing he will ever use a computer for! Thanks!

• Booting Windows off new SSD from grub boots old Windows instead

  - by wuputah

  After a new SSD install, I have: Original Windows 7 on sdc1 (to be retired) Copy of Windows 7 on sdb2 A Windows system partition on sdb1 Ubuntu 12.04 on sda, /boot and ergo grub is on sda1 Grub is MBR on sda and set to boot from BIOS. I prefer to not change this; grub is great! I've run update-grub (the Ubuntu grub scripts are, at present, unaltered) and grub seems to be correctly configured as all options are available: I can boot any of the 3 Windows partitions and Ubuntu. I also ran the repair tool to get Windows to add both installations to BCD. The problem: choosing particular options seem to have no effect; the old version of Windows on sdc1 always boots. I'm stumped! My thought was to only boot Windows off sdb1, and then let BCD do the rest (present a menu to boot between sdb2 and sdc1, but I can't seem to get BCD to boot sdb2), but this has been unsuccessful. Reference: BCDEdit output

• Connecting to iSCSI Target

  - by Joost Verdaasdonk

  I've installed Microsoft iSCSI Software Target 3.3 on a server 2008 R2 machine and created a new iSCSI Target. In the target I created a new Virtual Disk. From another server I started iSCSI Initiator and in Targets | Target I typed the IP of the Target. (Also tried DNS name.) But when I click Refresh I never see the target. Through googling I found this Youtube tut from a French guy doing pretty much what I did (only difference is I'm in a domain). I first though that maybe Port 3260 was closed but its not I can telnet to it. Also disabled all firewalls to see if that was blocking anything... No luck so far. Does anybody know of possible reasons why I can't connect to the iSCSI Target? If I can provide more info please let me know what's needed? Extra info: I've used this tut to set things up.

• Is it safe to operate a laptop without battery?

  - by leladax

  I know it's 'unsafe' in terms of data loss but I noticed motherboards still have some of their circuits on power when they are plugged in [e.g. a circuit that must wait for power-on signals is certainly one of them]. Hence, I wondered if it would increase the life of the laptop if the battery was simply off. Let alone that may also increase battery life, but that's the least of my concerns. Notice the main point is to plug it off on hibernate and have no power source whatsoever for the duration of being off (apart from the clock battery). (i.e. saving having to plug off the battery every time)

• Printing Off Center or Images Offset After Upgrade to 14.04 LTS (Brother HL-2240)

  - by fortitude

  :) I have a very frustrating problem with my Brother HL-2240 under Ubuntu 14.04. Bear in mind this was working perfectly under Ubuntu 13.10. In Firefox, when I print a webpage, all of the images are off center and cut off, this is a big deal for my work. In Google Chrome, when I print a webpage, the page is off center, toward the right margin. In Opera, when I print a webpage, all of the white areas within the margins are black, using a lot of toner. PDF opened in document viewer, prints off center. Steps I have taken to troubleshoot: 1) Playing with the printer settings, resetting to defaults, etc. 2) Un-installing the Brother driver and re-installing (linux-brprinter-installer-2.0.0-1 from the Brother website), which works perfectly in Ubuntu 13.10. I see a similar, un-answered question, here. Hopefully this question provides some additional clarity to the matter. If anyone would like some additional detail because she or he is willing to help, please let me know. I can scan output from the printer to show you. Thank you.
