  • Shared folder on mac: mounted on ubuntu but not writable

    - by Max Williams
    I've got a mac (called 'maxw-hackbook') with a folder (called 'work') which i've shared, making it "read & write" by me, "staff" and everyone. I've then mounted it to a folder on my ubuntu laptop, as follows: #on ubuntu laptop $ smbtree -s WORKGROUP \\MAXW-HACKBOOK maxw-hackbook \\MAXW-HACKBOOK\IPC$ IPC Service (maxw-hackbook) \\MAXW-HACKBOOK\work work $ sudo smbmount //MAX-HACKBOOK/work/ /mnt/hackbook-work -o ip=192.168.1.228,username=Max,password=passwordonmacbook,w This has successfully mounted the "work" folder on the macbook to the /mnt/hackbook-work folder in ubuntu. But, it's read-only, even though i've set the shared folder (on the mac) to be "read and write" by everybody. I need to have write access to that folder on the mac. Can anybody see what i've done wrong? thanks, max

  • How to avoid overflow in expr. A * B - C * D

    - by Ir0nm
    I need to compute an expression which looks like: A*B - C*D, where their types are: signed long long int A, B, C, D; Each number can be really big (not overflowing its type). While A*B could cause overflow, at same time expression A*B - C*D can be really small. How can I compute it correctly? For example: MAX * MAX - (MAX - 1) * (MAX + 1) == 1, where MAX = LLONG_MAX - n and n - some natural number.

  • Windows virtual wifi hostednetwork - set max number of clients?

    - by user1327408
    I'm building an app that has functionality that creates on the fly a new virtual wifi utilizing the Windows 7 / 2008 features. I can create it just fine, but am looking how to limit the maximum number of connections. By running a "netsh wlan show hostednetwork" command to view my settings - it shows (by default 100), but it HAS to be somewhere in the registry right? - I can't see any settings available for this either at the command line or using the api - so I have to assume it's stored in the reg. I see vwifi and hostednetwork registry keys in HKLM\System\CurrentControlSet\ - Wlansvc\parameters\hostednetworksettings, etc... but can't find any reference to add a "MaxClients" value (or similar) - would like to limit it to only one connection. Has anyone seen any references to this, or know how to do it?

  • kvm and qemu host: Is there a limit for max CPUs (Ubuntu 10.04)?

    - by Valentin
    Today we encountered a really strange behaviour on two identical kvm and qemu hosts. The host systems each have 4 x 10 Cores, which means that 40 physical cores are displayed as 80 within the operating system (Ubuntu Linux 10.04 64 Bit). We started a Windows 2003 32 Bit VM (1 CPU, 1 GB RAM, we changed those values multiple times) on one of the nodes and noticed that it took 15 minutes until the boot process began. During those 15 minutes, a black screen is shown and nothing happens. libvirt and the host system show that the qemu-kvm process for the guest is almost idling. stracing this process only shows some FUTEX entries, but nothing special. After those 15 minutes, the Windows VM suddenly starts booting and the Windows logo occurs. After a few seconds, the VM is ready to be used. The VM itself is very performant, so this is no performance issue. We tried to pin the CPUs with the virsh and taskset tools, but this only made things worse. When we boot the Windows VM with a Linux Live CD there is also a black screen for several minutes, but not as long as 15. When booting another VM on this host (Ubuntu 10.04) it also has the black screen problem, and also here the black screen is only shown for 2-3 minutes (instead of 15). So, summerinzing this: Each guest on each of those identical nodes suffers from idling a few minutes after being started. After a few minutes, the boot process suddenly starts. We have observed that the idling time happens right after the bios of the guest was initialized. One of our employees had the idea to limit the amount of CPUs with maxcpus=40 (because of 40 physical cores existing) within Grub (kernel parameter) and suddenly the "black-screen-idling"-behaviour disappeared. Searching the KVM and Qemu mailing lists, the internet, forums, serverfault and other various sites for known bugs etc. showed no useful results. Even asking in the dev IRC channels brought no new ideas. The people there recommend us to use CPU pinning, but as stated before it didn't help. My question is now: Is there a sort of limit of CPUs for a qemu or kvm host system? Browsing the source code of those two tools showed that KVM would send a warning if your host has more than 255 CPUs. But we are not even scratching on that limit. Some stuff about the host system: 3.0.0-20-server kvm 1:84+dfsg-0ubuntu16+0.14.0+noroms+0ubuntu4 kvm-pxe 5.4.4-7ubuntu2 qemu-kvm 0.14.0+noroms-0ubuntu4 qemu-common 0.14.0+noroms-0ubuntu4 libvirt 0.8.8-1ubuntu6 4 x Intel(R) Xeon(R) CPU E7-4870 @ 2.40GHz, 10 Cores

  • iperf max udp multicast performance peaking at 10Mbit/s?

  • Driver Max - Updating drivers that are not digitally signed - good or bad?

    - by Paul
    Win7 Home Prem 32-bit I am currently using DriverMax to keep my drivers up to date. Sometimes it suggests that a newer driver is available for download but the driver is not digitally signed. Is it safe to update to an unsigned driver or not? What are the implications of signed vs unsigned drivers? I always create a system restore point before updating any drivers anyway and i know i can rollback a driver.

  • We are moving an Access based corporate front-end into a Web-based App

    - by Max Vernon
    We have an enterprise application with a front end written in Microsoft Access 2003 that has evolved over the past 6 years. The back end data, and a fair amount of back-end logic is contained within several Microsoft SQL Server databases. This front end app consists of around 180 forms, and over 120,000 lines of code, and interacts with VB.Net DLLs that support various critical functions used by our sales force. The current system makes use of 3 monitors to display various information; the Access app uses COM+ to control Microsoft Outlook and Internet Explorer for various purposes. The Access front end sometimes occupies 2 screens, automatically resizing itself based on Windows API-reported screen dimensions. The app also uses a Google map to present data to our agents, and allows two-way interactivity with the map through COM+ connectivity to JavaScript contained in the Google map. At the urging of senior management, we are looking to completely rewrite this application using some web-based technology, such as ASP.Net or perhaps a LAMP stack (the thinking with the LAMP stack thing is "free" is pretty cheap). We want to move to a web-based app so we can eliminate the dependency on our physical location for hiring new sales force members. Currently, our main office is full to capacity, and we need to continue growing the company. Does anyone have any thoughts on what would be the best technology to use for a web-based app of this magnitude? Keeping in mind the app is dependent on back-end services on our existing infrastructure. The app handles financial data and personal customer data, among other things. [I've looked at Best practices for moving large MS Access application towards .Net? and read the answers, and most of the comments. Interesting reading, and has some valid points, but our C.O.O. and contracted Software Architect are pushing for a full web-based app, not a .Net Windows App]

  • How can I view localized versions of my site?

    - by Max Vernon
    We are adding internationalization to our site. We are getting the client's IP address from the headers and looking it up against the IP2location database to get the client's country. Several of our clients reported seeing a blank page over the weekend. We'd like to be able to get screenshots or use a browser from many different countries on an ongoing basis for testing code changes. I need to know what the site looks like when accessed from various countries since there are several elements that vary by country. I've used Tor and Vidalia, along with the Tor customized Firefox browser however it appears the CSS is getting mangled. I have also used http://webpagetest.org to check the site, however the screenshot it gives is too small to be really useful. Is there a site or a service I can use to get screenshots or interact with my website from various countries?

  • Should I be worry about max number of files in a folder in *NIX filesystems?

    - by ??????
    In a social networking project we want to store user's avatars in a folder. I think in one year or two it'll reach to 140K (I've seen this issue before and it will be around this number). I want to spread files in folders. If a folder contains 1000 files then create another folder and do store files from 1001 to 2000. Is this a good approach or I'm just very cautious about the issue? (File system : EXT3)

  • Max. Temp. on Intel Burn Test for Stock Dell Precision T3500

    - by HK1
    I'm troubleshooting an issue on a Dell Precision T3500. As part of my troubleshooting I've decided to try running a stress test using Intel Burn Test software. This machine is a stock configuration with 12GB of RAM and a Xeon W3670 processor (nothing overclocked). When I run IBT using the standard mode, SpeedFan reports a processor temperature in excess of 80C. I've seen numbers as high as 90C but even at that temperature the machine does not become unstable or crash. However, it seems way too high. This processor has a TCase of 67.9C according to Intel's website. I'm guessing that means I'm in the danger zone any time I go over that temperature. I've checked the cooling system and everything looks fine. I've even took out the heat sink and reinstalled it with new thermal compound. This did not appear to make the problem better or worse. Is there a discrepancy somewhere here in the way temperatures are measured or displayed? I've also tried using HWMonitor from CPUID and it reports the same temperatures. Should I just let the Standard Test go and disregard the temperature outputs?

  • What's the max Windows 7 access possible to restrict tampering with single service?

    - by Crawford Comeaux
    I'm developing an ADHD management system for myself. Without going into detail (and as silly as it may sound for a grown man to need something like this), I need to build a me-proof service to run on my Windows 7 Ultra laptop. I still need fairly complete access to the system, though. How can I set things up so that I'm unable to "easily" (ie. within 3-5 mins without rebooting) stop the service or prevent it from running?

  • How to change x-axis min/max of Column chart in Excel?

    - by Ian Boyd
    Here i have a column chart of binomial distribution, showing how many times you can expect to roll a six in 235 dice rolls: Note: You could also call it a binomial mass distribution for p=1/6, n=235 Now that graph is kinda squooshed. i'd like to change the Minimum and Maximum on the horizontal axis. i'd like to change them to: Minimum: 22 Maximum: 57 Meaning i want to zoom in on this section of the graph: Bonus points to the reader who can say how the numbers 22 and 57 were arrived at If this were a Scatter graph in Excel, i could adjust the horizintal axis minimum and maximum as i desired: Unfortunately, this is a Column chart, where there are no options to adjust the minimum and maximum limits of the ordinate axis: i can do a pretty horrible thing to the graph in Photoshop, but it's not very useful afterwards: Question: how to a change the x-axis minimum and maximum of a Column chart in Excel (2007)?

  • What is the max connections via remote desktop for a small server?

    - by Jay Wen
    I have a small server running MS Server 2012. The CPU is a Xeon E3-1230 V2 @ 3.30GHz, 4 Cores, 8 Logical Processors, 8 GB RAM. Main HD is a Samsung 840, and the big storage is a 4 disk WD Black Raid 10 Array in a Synology NAS enclusure. My question is: given this hardware, approximately how many users can the system support via "Remote Desktop Connection"? Assume there are no licensing limits. These are not admin users. I know there is a two admin limit. This boils down to: What resources does one remote connection require? RAM? % of the CPU? Networking bandwidth? I guess the base case would be for a conection where the user is inactive or simply browsing cnn. Once you know this, you know how many you could fit on the machine before something is maxed-out. In reality, users would be mostly on Excel (multi-MB spreadsheets). I know the approx. resources currently required by each copy of Excel.

  • Do memory cards have any max file size limitation?

    - by Dmitriy R
    I am not sure where to ask this question, so perhaps it is physical limitation. I have a 8 GB flash micro SD memory card. When I copy any file size of up to few gigabytes, copying happens normally. But if I am trying to copy file over 4 GB file, then the system tells me like insufficient memory on card, although 8 GB is available. So perhaps only 32 bit address is used for keeping size of file in micro SD card, or is my micro SD defective?

  • Is there a limit of max. number of files in external hard drive folder?

    - by tfs
    I have a FAT32 external hard drive where I keep backups downloaded from webserver. I have a directory with 30 subdirectories. One of the subdirectories contains 21381 files and when I try to copy more files into this directory I get 0x80070052 error. However,it's possible to copy one more file in this directory (only one) if I make it's name shorter (8 characters instead of 22 as it's original name). How do I solve this problem? Now I can not synchronize external hard disk files with server files which is very important for me.

  • How can I set `less` or `more` max lines (scrollable height) limit/boundary in linux?

    - by Rudie
    (Sorry for the title. Any suggestions?) I've set my commandline PS1 to cover 3 lines: white space user, server and pwd $ or # to input I think less (or more?) is configured to break after window's height - 1, because when I do a $ git log, the first two lines are invisible at the top of the window and the rest is scrollable. I'm not sure who handles this scrolling and its configuration, but I assume GIT uses less/more. Where can I configure that my scrollable window is window height - 3 lines and not window height - 1? More info: If I cat lines.txt | less with a 23 line file, it shows the entire file and no scrolling. If I do the same with a 24 line file, it doesn't show line 1 (and no scrolling). With 25 lines: doesn't show lines 1 and 2 (and no scrolling). With 26 lines: shows line 1 and scrolling! The less breakpoint is at the wrong height...

  • What is the performance penalty of XML data type in SQL Server when compared to NVARCHAR(MAX)?

    - by Piotr Owsiak
    I have a DB that is going to keep log entries. One of the columns in the log table contains serialized (to XML) objects and a guy on my team proposed to go with XML data type rather than NVARCHAR(MAX). This table will have logs kept "forever" (archiving some very old entries may be considered in the future). I'm a little worried about the CPU overhead, but I'm even more worried that DB can grow faster (FoxyBOA from the referenced question got 70% bigger DB when using XML). I have read this question http://stackoverflow.com/questions/514827/microsoft-sql-server-2005-2008-xml-vs-text-varchar-data-type and it gave me some ideas but I am particulairly interrested in clarification on whether the DB size increases or decreases. Can you please share your insight/experiences in that matter. BTW. I don't currently have any need to depend on XML features within SQL Server (there's nearly zero advantage to me in the specific case). Ocasionally log entries will be extracted, but I prefer to handle the XML using .NET (either by writing a small client or using a function defined in a .NET assembly).

  • Is there a max recommended size on bundling js/css files due to chunking or packet loss?

    - by George Mauer
    So we all have heard that its good to bundle your javascript. Of course it is, but it seems to me that the story is too simple. See if my logic makes sense here. Obviously fewer HTTP requests is fewer round trips and hence better. However - and I don't know much about bare http - aren't http responses sent in chunks? And if a file is larger than one of those chunks doesn't it have to be downloaded as multiple (possibly synchronous?) round trips? As opposed to this, several requests for files just under the chunking size would arrive much quicker since modern web browsers download resources like javascripts in parallel. Even if chunking is not an issue, it seems like there would be some max recommended size just due to likelyhood of packet loss alone since a bundled file must wait till it is entirely downloaded to execute, versus the more lenient native rule that scripts must execute in order. Obviously there's also matters of browser caching and code volatility to consider but can someone confirm this or explain why I'm off base? Does anyone have any numbers to put to it?

  • Properly changing Ajax MultiHandle Slider parameters on postbacks

    - by Matthew PK
    Hi all, In VS2010 I have VB.NET codebehind aspx pages and I'm using Ajax multihandleslider extensions to filter search results on numerical values. Fistly, the multihandle sliders don't display in the designer... I have to remove the slider targets tag: In order to make it display in the designer... this isn't so much a big issue but an annoyance. I am displaying items in a given category. So I get the max and min prices for all items in that category and assign the sliderextension max/min values appropriately. This works fine until... I change the item category and go get a new max/min value for the slider control. I set the max/min values, then I set the target textbox values each to the corresponding max/min values. The slider handles don't repaint (or init?) properly Like say for example my initial min/max is 1/100 if I do a full postback and change the max value to 1000 then the slider bar (correctly) stays the same size but the handle appears WAYYYY to the right off the page and I have to scroll to it. When I click it, it shoots back onto the slider bar. I'm pulling my hair out... why do the slider handles only appear properly when I first set the min/max values?
