  • Adding a 2008 server to a 2003 Domain with DNS devolution?

    - by mvdwege
    I'm running into a problem adding a 2008 server to our existing 2003 domain, and as I am not a Windows admin, I'm not getting the problem here. Some reading around on Technet seems to indicate that DNS devolution is the issue. Here's the setup: DNS for the entire company is hosted on a Unix server running Bind, including the service records for the Windows domain. Our toplevel is company.local, and functional domains are in subdomains, such as mgt.company.local (our management servers). Our Windows servers live mostly in office.company.local, but some of them live in .mgt.company.local and .customers.company.local. The 2003 servers all succesfully authenticate against company.local as the Windows domain. Their position in the infrastructure is set by setting the primary DNS suffix under the network settings and the computer name dialog. Trying to do the same with a brand new 2008 install throws an error though: "Changing the Primary Domain DNS name of this computer to office.company.local failed [...] The specified server cannot perform the requested operation" I tried googling, but the closest I came was the Technet article on DNS Devolution, and I can't make heads nor tails on how to apply that to my case. Addendum 2012-10-23: The problem is not joining the domain, that works, the problem is that it joins with the wrong name, as .company.local, instead of .office.company.local. So far everything works, but I'm rather afraid to run production like this, because sooner or later something is going to complain about the AD name not matching DNS.

  • How to autostart service in ANY linux?

    - by user329115
    I need to install the dumbest possible service (a binary) and have it reliably run as the current user at boot (or login, whatever) at as many platforms as possible (of the aging point-of-sale type). The app monitors another archives generated by another app in the user-session. Startup alternatives considered: init.d @reboot in crontab a .desktop file in ~/.config/autostart a myriad of other solutions including .profile and .bashrc All of the above break down at some point. The problems stem from not wanting to run as root (I want the files generated to be user-accessible), and not having a way to reliably get the current user name in sudo on all platforms. Ideally not even sudo can be assumed available. Hey, I just want to run something on boot and I have "root" power to do so. Windows get the job done easily enough. This isn't rocket science, is it?

  • IE8 page reload hangs

    - by Rod
    When a 7mb HTM file is first opened (by clicking on the file icon or using Open With), both IE8 and Firefox display this browser file quickly. After the file is closed, Firefox will reopen this file quickly, but IE8 appears to hang during the reopen. Clearing the IE cache does not help. However, IE will reopen the file quickly again only if the File/Open/Browse feature of the menu bar is used (clicking on the file icon can be used only once between computer reboots). Testing suggests that the problem relates to the number of HTML hyperlinks pointing to another part of the file. There are many hyperlinks, but they are not a problem during the first load of the document (between computer reboots). What needs to be fixed to avoid use of the workaround? Using Windows XP SP3 Update 6/23/12 - Controlled testing shows that the number of hyperlinks is not the problem. The way this large file is opened is the difference: 1) from the IE menu bar, File/Open/Browse is consistent and fast (but not as fast as FF). 2) clicking on the file name in the folder (even when IE is the default program for this file type) causes a much delayed load of the file. Creating a smaller file demonstrates the delayed load, but verifies that the load eventually occurs.

  • Internet keeps connecting and disconnecting

    - by OmerPT
    I have a PC running 32bit Windows 7 Professional. My wireless internet card is Edimax EW-7128G, it is inside my computer case and it is connected to an antenna. My problem is: I have a wireless connection to my router, the signal is fine and it's not slow or anything, but it just keeps disconnecting every 30 seconds or so, then connects back, then it disconnects, then connects back and so on. This is new - it only started about a week ago, everything worked just fine until then. I know it's not a problem with the router because: Other computers can connect to it easily and they work just fine, no disconnections (My phone too). I know it's not a problem with the computer or the wireless card itself because: I have Ubuntu installed side-by-side with my Windows, and when I switch to Ubuntu the internet works great. This caused me to think it's probably a problem with the wireless card drivers installed on windows (Ubuntu auto-installed them, I installed them manually on windows): I tried uninstalling them, and then installing them back again, sadly that didn't help. I'm kind of lost here - can anyone think of anything else I should try? Thanks :)

  • Restore only one partition of Windows Backup

    - by VitoShadow
    I have a MacBook Pro with an HD partitioned. This HD was divided in two partitions: the first was about 650 GB, with OS X installed, and the second one (created with BootCamp Assistant) was about 100 GB, with Windows 7 installed. I needed more space for Windows, so I decided to backup the Windows partition using the Windows backup tool, from Control Panel. I created an image of my partition, stored it in an external HD, and now I'm trying to use it. In order to give more space to Windows, I formatted the HD, and recreate a new partition table, with the first partition of about 250 GB (with OS X) and the second of the exactly size of the previous partition in which was installed Windows (about 100 GB); thre rest was empty space. In the second, I tried to restore the Windows backup. I plugged in the Windows Installation CD (with the HD with the backup connected to the computer), and select the option "Repair your computer". Then, I choose the image of the backup (automatically recognized), and I try to restore it. The problem is that now the System Recovery Tool wants to format all the HD, in order to install only Windows! In this way, I should lose everything, also the MacOS partition! Is there a way to install the backup only in the Windows partition?

  • How to Find Out Who Made an ISO Disk?

    - by Qwertyfshag
    If a file is saved using Microsoft word or some other type of program, you can right click on the file to find the properties, which will indicate the computer that created the file. Is there anyway to find out who created an ISO disk image on a CD or DVD? I assume that there should be no meta data on the disk because an ISO disk image should be an exact duplicate of the original. Is my assumption correct? To illustrate with an example, let's say you found a CD at a cafe or something. You decide to look at the CD with your computer. You find out that it is an "Ubuntu live CD" that was obviously created from an ISO file. Is there any way to find out who burned the CD? Or, on the flip side, let's say you were the one that burned the "Ubuntu live CD" and you lost it. Would somebody be able to know that it was you who made the CD? Can they get any info about the maker?

  • What could be causing windows to fail to sleep or hibernate, and revert system settings?

    - by xdumaine
    I am running Windows 8.1 on my system (Dell e6520) and the symptoms are this: My PC won't sleep or hibernate. It the screen turns off, but the fans just run and run, and after a little while, it completely shuts down, and when I start it back up, everything is closed, like it was a fresh boot/restart. I'm have a weird issue with outlook described here and the fix works fine - modifying a registry value. The weirder part is that after my computer fails to sleep or hibernate, and it starts back up, the registry value is GONE, like I never modified it, and thus the outlook error message is back. I thought maybe a graphics driver was preventing the sleep/hibernate, so I attempted to uninstall the NVIDIA graphics driver and control panel. HOWEVER, once the computer fails to sleep/hibernate, the NVIDIA graphics driver and control panel appear BACK on my system, like I didn't uninstall them. What could be happening here? I really need to be able to sleep/hibernate so I don't lose work or my work state, and these issues are really concerning. What I've tried, without success: Uninstalling graphics driver mentioned above Disabling hibernate and using sleep disabling/re-enabling hibernate Disabling startup items Sleeping as local system admin account disconnecting all USB, network, and bluetooth devices

  • Copy past speed very slow for a large number of files on Windows [closed]

    - by Arno2501
    I've run the following test I've created a folder containing 15'000 files of 400 bytes using this batch : @ECHO off SET times=15000 FOR /L %%i IN (1,1,%times%) DO ( fsutil file createnew filename%%i.txt 400 ) then I copy past it on my Windows Computer using this command : robocopy LargeNumberOfFiles\ LargeNumberOfFiles2\ After it has completed I can see that the transfer rate was 915810 Bytes/sec this is less than 1 MB/s. It took me several seconds to copy 7 MBytes Please note that this is very slow. I've tried the same with a folder with a single file of 50 Mbytes and the transfer rate is 1219512195 Bytes/sec. (yeah GB/s) instantaneous. Why copying large number of files take so much time - ressources on a windows filesystem ? Please note that I've tried to do the same on a linux system which runs on the same computer in a virtual machine (vmware player) with ext3 filesystem. I use the cp command and the copy is instantaneous ! Please also note the following : no antivirus I've tested that behaviour on multiple windows computers (always ntfs) i always get comparable results (transfer rate under 1MB/s avg 7-8 seconds to copy 7 MBytes) I've tested on multiple linux ext3 system the copy is always instantaneous for that amount (15000 files of 400 bytes) The question is about understanding what makes windows filesystem so slow to copy large number of files compared to a linux one for instance.

  • Strange focus bug in Firefox (chrome vs content)

    - by Marius
    Here is a strange bug I'm experiencing in Firefox: I can only use either the chrome, or the content, not both at the same time! For example, I can click on tabs and the toolbar icons, focus the search bar and write in it as well as the address bar, but if I try to click on anything in the content (eg a link or a textfield to write something), then nothing happens. The mouse pointer doesn't change either, it just stays a pointer when I hover over things, and the links I hover don't react either. But if I alt-tab to another program (or click on it in the taskbar), then back to Firefox, then I can use the area that I click on. So if I click somewhere on the webpage to get focus back to Firefox, then I can click on links and write things (like this text), but I cannot click on tabs or refresh or anything else in the chrome. I can't even click on the minimize, restore and close icons! To get focus back on the chrome I have to alt-tab to another program, and then click on the chrome to get back to Firefox to be able to use the chrome again. I've tried closing and starting it again, but the bug is still there. I have experienced this before, but I don't remember what I did to fix it. This bug seems to occur sometimes when I wake up the computer from standby, but I leave by computer in standby all the time, so that is not the only factor.

  • Folder doesn't show up in explorer, cmd, and python even though I can access it, how can I fix this?

    - by Miebster
    I am accessing another computer on the network using a mapped network drive. The path looks like \\192.168.0.100\d$ which is mapped to my computer's "m" drive. I can access, view, create, delete, move, etc folders on this drive. However, some folders don't show up in windows explorer, even tho I can access them. Example: Lets say that M:\stuff\more_stuff is a directory. What I can't do: When windows explorer is pointed at M:\stuff I can't see more_stuff In cmd prompt pointed at M:\stuff "dir" doesn't find more_stuff In cmd prompt pointed at M:\stuff "dir /a" doens't find more_stuff In python, os.listdir at M:\stuff doens't find more_stuff What I can do: Typing M:\stuff\more_stuff into the address bar lets me access the folder like normal. Because there is no indication that this folder even exists, there could be more like them. I have no way of knowing how many folders are magically hidden on this mapped drive. What are some steps I can do to figure out why this folder is hidden? (With the end goal of making it no longer hidden).

  • How to merge Windows registry hives directly without converting them to an intermediate text based file?

    - by Registrar
    Help! I'm going to get fired if I can't figure out how to do this by tomorrow. Microsoft Windows stores its registry databases (known as "registry hives" - there's actually a backstory to the origin of this name, but I digress) in a proprietary binary format. Answer this correctly or you lose your job: Let H-sub-A be the registry hive of Computer A, and let H-sub-B be the registry hive of Computer B. Create a registry hive H-sub-A-prime (in the native binary format) that contains all of the registry keys and values in both H-sub-A and H-sub-B. If there is overlap, let the value from H-sub-B overwrite the value in H-sub-A. Sure, you can import a text-based patch file (e.g., "FOO.REG") to modify the registry, but can you merge two registry hives in their native binary format? Answers that involve exporting the registry to a text file (e.g., "FOO.REG") will receive no credit. You may only use software included with Microsoft Windows (any version) and / or third-party tools that are free of charge.

  • Would a USB hub work in reverse?

    - by Tim
    Imagine for a moment with a 4 port USB hub. Normally how this would work is the hub has one plug that goes to the computer, then 4 ports that you can plug in other things to (thumb drive, keyboard, mouse etc). I am wondering if I can use it in reverse. So I would have 1 keyboard going in to the hub, and then plug in male to male usb cables from the 4 ports to 4 different PCs, my aim is that when a key is pressed on the keyboard all 4 PCs will receive it as if the keyboard were plugged in to them. Does anyone know if this would work? And if not does anyone have any ideas how I could get the same effect? EDIT: So I am looking for more of a KVM switch type device rather than a USB hub. However all of the KVM switches I've found use some sort of mechanism to select which computer you'll be using. (some are physical switches / buttons, others do it via software "automatically" some how) However I need to have 1 keyboard hooked up to 2 computers and when I press a key on the keyboard I want the keypress to be sent to both computers simultaneously, not to one or the other. Does anyone know if KVMs with this feature exist?

  • Most simple way to do holiday calculation?

    - by brainfrog
    I want to make a little free calendar program to help me and others calculate how much time we have got left in a project. I mean real working time, not just time. Time in a raw form is not saying much. Typically when my boss tells me that I have time until 05-05-2011 it doesn't tell me really how much time I have to do my job. You know...so many things stop me from work: A) beeing at home, not at work (so called "free time" or "spare time"). That is in my case I work exactly 8 hours a day and then the cleaning ladies throw me out of the office with their incredible loud industrial vacuum cleaners every evening (my boss accepts that as an excuse to go home in time, regularly). B) weekends, or more precisely saturdays and sundays C) official holiday rescuing me from having to go to work. what I want to do is make a little utility which tells me how many working hours I really have in a given time period. The first two things A and B are pretty easy to implement. But the last thing C scares my pants off. Holidays. OOOHHH man. You know what that means. Chaos. Pure chaos. The huge question is: HOW TO CALCULATE HOLIDAYS?! Since I want my program to be useful for anyone anywhere in the world, I can't just hardcode all holidays for my little town. So which options do I have? I) I could hand-craft downloadable lists of holidays. Users search them within the application and download them from an webserver. Or I ship all of them in the package. But I would get very, very old if I tried that by myself for every country, state and town. II) I make an initial data sheet with holidays for my town, and don't care about the rest. However, I make that sheet with an how-to public, so that everyone who feels like beeing very nice can provide holiday data for his country / region / whatever. Those are made public on a webserver and everyone can get the data packages he/she needs for the app. III) ? I care a lot about usability. I don't want to make an ugly linux hack style hard to use app that only computer freaks can use. So you need to tell me more about holiday science. I was never really clever at this. I assume every single country in the world has it's own set of holidays. In every country there may be several states. For example the US has some, and Germany has also some states. Holidays vary from state to state. But I know from an good programmer he told me never assume anything. So the questions about holiday science are: Which categories do I need to make holiday-data-packs searchable? A guy from India should find quickly his holiday data pack, and a guy from Sillicon Valley should find his pack as equally fast. It makes most sense to me to filter for COUNTRY STATE WHATEVER. Like a drill-down-search. Did I miss something? What would be the best data format to hold holiday information? A holiday has a start and end date and a name. That should be enough. Would I put all this stuff in thousands of XML files? How would you go about this? Any hint / help is highly welcome! Thanks to everyone!

  • Generate JFreeChart in servlet

    I'm trying to generate graphs using JFreeChart. I added record in web.xml, installed jfreechart library. Compiled servlet.

  • SQLAuthority News – Author Visit to Nepal TechMela – 2 Technical Sessions

    - by pinaldave
    Microsoft MDP Nepal is going to organize a Tech Mela for the IT community of Nepal on March 29 & 30, 2010 (2066 Chaitra 16 & 17), Monday and Tuesday,  at the Russian Center for Science & Culture, Kamalpokhari, Kathmandu. The objective of the event is to enhance and exchange knowledge about Information Technology, as well as Microsoft products and technologies, with the IT community. I am very excited to attend this one-of-a-kind event in Nepal. I will be giving two presentations in the said event, which includes: 1) Become An Efficient Developer – Learn The Tricks of SQL Server Management Studio (SSMS) There are so many features in SQL Server Management Studio that we may not know or use all of them. This presentation will impart tricks and tips of SQL Server Management Studio to the event goers. This aims to make you an efficient developer by having an edge over the other developers. 2) Good, Bad and Ugly: The Story of Index Index is often considered as the sure shot tool of improving the performance of any query. Learn the basics with examples and discover the good, bad and ugly sides of Index. This session will help you efficiently write queries in future. I am very excited to attend this special event as this is the very first time I will be presenting in technical sessions in Nepal. If you are in Nepal, I strongly suggest that you go to this once-in a lifetime IT fair.

  • Option Trading: Getting the most out of the event session options

    - by extended_events
    You can control different aspects of how an event session behaves by setting the event session options as part of the CREATE EVENT SESSION DDL. The default settings for the event session options are designed to handle most of the common event collection situations so I generally recommend that you just use the defaults. Like everything in the real world though, there are going to be a handful of “special cases” that require something different. This post focuses on identifying the special cases and the correct use of the options to accommodate those cases. There is a reason it’s called Default The default session options specify a total event buffer size of 4 MB with a 30 second latency. Translating this into human terms; this means that our default behavior is that the system will start processing events from the event buffer when we reach about 1.3 MB of events or after 30 seconds, which ever comes first. Aside: What’s up with the 1.3 MB, I thought you said the buffer was 4 MB?The Extended Events engine takes the total buffer size specified by MAX_MEMORY (4MB by default) and divides it into 3 equally sized buffers. This is done so that a session can be publishing events to one buffer while other buffers are being processed. There are always at least three buffers; how to get more than three is covered later. Using this configuration, the Extended Events engine can “keep up” with most event sessions on standard workloads. Why is this? The fact is that most events are small, really small; on the order of a couple hundred bytes. Even when you start considering events that carry dynamically sized data (eg. binary, text, etc.) or adding actions that collect additional data, the total size of the event is still likely to be pretty small. This means that each buffer can likely hold thousands of events before it has to be processed. When the event buffers are finally processed there is an economy of scale achieved since most targets support bulk processing of the events so they are processed at the buffer level rather than the individual event level. When all this is working together it’s more likely that a full buffer will be processed and put back into the ready queue before the remaining buffers (remember, there are at least three) are full. I know what you’re going to say: “My server is exceptional! My workload is so massive it defies categorization!” OK, maybe you weren’t going to say that exactly, but you were probably thinking it. The point is that there are situations that won’t be covered by the Default, but that’s a good place to start and this post assumes you’ve started there so that you have something to look at in order to determine if you do have a special case that needs different settings. So let’s get to the special cases… What event just fired?! How about now?! Now?! If you believe the commercial adage from Heinz Ketchup (Heinz Slow Good Ketchup ad on You Tube), some things are worth the wait. This is not a belief held by most DBAs, particularly DBAs who are looking for an answer to a troubleshooting question fast. If you’re one of these anxious DBAs, or maybe just a Program Manager doing a demo, then 30 seconds might be longer than you’re comfortable waiting. If you find yourself in this situation then consider changing the MAX_DISPATCH_LATENCY option for your event session. This option will force the event buffers to be processed based on your time schedule. This option only makes sense for the asynchronous targets since those are the ones where we allow events to build up in the event buffer – if you’re using one of the synchronous targets this option isn’t relevant. Avoid forgotten events by increasing your memory Have you ever had one of those days where you keep forgetting things? That can happen in Extended Events too; we call it dropped events. In order to optimizes for server performance and help ensure that the Extended Events doesn’t block the server if to drop events that can’t be published to a buffer because the buffer is full. You can determine if events are being dropped from a session by querying the dm_xe_sessions DMV and looking at the dropped_event_count field. Aside: Should you care if you’re dropping events?Maybe not – think about why you’re collecting data in the first place and whether you’re really going to miss a few dropped events. For example, if you’re collecting query duration stats over thousands of executions of a query it won’t make a huge difference to miss a couple executions. Use your best judgment. If you find that your session is dropping events it means that the event buffer is not large enough to handle the volume of events that are being published. There are two ways to address this problem. First, you could collect fewer events – examine you session to see if you are over collecting. Do you need all the actions you’ve specified? Could you apply a predicate to be more specific about when you fire the event? Assuming the session is defined correctly, the next option is to change the MAX_MEMORY option to a larger number. Picking the right event buffer size might take some trial and error, but a good place to start is with the number of dropped events compared to the number you’ve collected. Aside: There are three different behaviors for dropping events that you specify using the EVENT_RETENTION_MODE option. The default is to allow single event loss and you should stick with this setting since it is the best choice for keeping the impact on server performance low.You’ll be tempted to use the setting to not lose any events (NO_EVENT_LOSS) – resist this urge since it can result in blocking on the server. If you’re worried that you’re losing events you should be increasing your event buffer memory as described in this section. Some events are too big to fail A less common reason for dropping an event is when an event is so large that it can’t fit into the event buffer. Even though most events are going to be small, you might find a condition that occasionally generates a very large event. You can determine if your session is dropping large events by looking at the dm_xe_sessions DMV once again, this time check the largest_event_dropped_size. If this value is larger than the size of your event buffer [remember, the size of your event buffer, by default, is max_memory / 3] then you need a large event buffer. To specify a large event buffer you set the MAX_EVENT_SIZE option to a value large enough to fit the largest event dropped based on data from the DMV. When you set this option the Extended Events engine will create two buffers of this size to accommodate these large events. As an added bonus (no extra charge) the large event buffer will also be used to store normal events in the cases where the normal event buffers are all full and waiting to be processed. (Note: This is just a side-effect, not the intended use. If you’re dropping many normal events then you should increase your normal event buffer size.) Partitioning: moving your events to a sub-division Earlier I alluded to the fact that you can configure your event session to use more than the standard three event buffers – this is called partitioning and is controlled by the MEMORY_PARTITION_MODE option. The result of setting this option is fairly easy to explain, but knowing when to use it is a bit more art than science. First the science… You can configure partitioning in three ways: None, Per NUMA Node & Per CPU. This specifies the location where sets of event buffers are created with fairly obvious implication. There are rules we follow for sub-dividing the total memory (specified by MAX_MEMORY) between all the event buffers that are specific to the mode used: None: 3 buffers (fixed)Node: 3 * number_of_nodesCPU: 2.5 * number_of_cpus Here are some examples of what this means for different Node/CPU counts: Configuration None Node CPU 2 CPUs, 1 Node 3 buffers 3 buffers 5 buffers 6 CPUs, 2 Node 3 buffers 6 buffers 15 buffers 40 CPUs, 5 Nodes 3 buffers 15 buffers 100 buffers   Aside: Buffer size on multi-processor computersAs the number of Nodes or CPUs increases, the size of the event buffer gets smaller because the total memory is sub-divided into more pieces. The defaults will hold up to this for a while since each buffer set is holding events only from the Node or CPU that it is associated with, but at some point the buffers will get too small and you’ll either see events being dropped or you’ll get an error when you create your session because you’re below the minimum buffer size. Increase the MAX_MEMORY setting to an appropriate number for the configuration. The most likely reason to start partitioning is going to be related to performance. If you notice that running an event session is impacting the performance of your server beyond a reasonably expected level [Yes, there is a reasonably expected level of work required to collect events.] then partitioning might be an answer. Before you partition you might want to check a few other things: Is your event retention set to NO_EVENT_LOSS and causing blocking? (I told you not to do this.) Consider changing your event loss mode or increasing memory. Are you over collecting and causing more work than necessary? Consider adding predicates to events or removing unnecessary events and actions from your session. Are you writing the file target to the same slow disk that you use for TempDB and your other high activity databases? <kidding> <not really> It’s always worth considering the end to end picture – if you’re writing events to a file you can be impacted by I/O, network; all the usual stuff. Assuming you’ve ruled out the obvious (and not so obvious) issues, there are performance conditions that will be addressed by partitioning. For example, it’s possible to have a successful event session (eg. no dropped events) but still see a performance impact because you have many CPUs all attempting to write to the same free buffer and having to wait in line to finish their work. This is a case where partitioning would relieve the contention between the different CPUs and likely reduce the performance impact cause by the event session. There is no DMV you can check to find these conditions – sorry – that’s where the art comes in. This is  largely a matter of experimentation. On the bright side you probably won’t need to to worry about this level of detail all that often. The performance impact of Extended Events is significantly lower than what you may be used to with SQL Trace. You will likely only care about the impact if you are trying to set up a long running event session that will be part of your everyday workload – sessions used for short term troubleshooting will likely fall into the “reasonably expected impact” category. Hey buddy – I think you forgot something OK, there are two options I didn’t cover: STARTUP_STATE & TRACK_CAUSALITY. If you want your event sessions to start automatically when the server starts, set the STARTUP_STATE option to ON. (Now there is only one option I didn’t cover.) I’m going to leave causality for another post since it’s not really related to session behavior, it’s more about event analysis. - Mike Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • Advise on how to move from a .net developer role to a web developer role

    - by dermd
    I've been working primarily as a .net developer for the past 4 years for a financial services company. I've worked on .net 1.1, 2.0, 3.5 and have done the 3.5 enterprise app developer cert (not that that's worth a whole lot!). Before that I worked as a java developer with a bit of Flex thrown in for just over a year. My educational background is an Electronic and computer engineering degree, a higher diploma in systems analysis as well as one in web development (this was mainly java - JSP, Spring, etc) and a science masters in software design and development. I really feel like a change and would like to move to a different field to experience something different. I've done some courses in RoR and played around with it a bit in my spare time. Similarly I've done various web and mobile courses and done up some mobile webapps along with android and ios equivalents (haven't tried pushing them up to the app stores yet but may be worth tidying them up and doing that). I currently work long enough hours so find it hard to find time to work on too many side projects to get a decent portfolio together. But when I do work on the web stuff I do find it really enjoyable so think it's something I'd like to do full time. However, since my experience is pretty much all .net and financial services I find it very hard to get my foot in the door anywhere or get past a phone screen unless their specifically looking for someone with .net knowledge. What is the best way to move into a web development role without starting from scratch again. I do think a lot of the skills I have translate over but I seem to just get paired with .net jobs whenever I look around? Apart from js, jquery, html5, objective C are there any other technologies I should be looking into?

  • Geek it Up

    - by BuckWoody
    I’ve run into a couple of kinds of folks in IT. Some really like technology a lot – a whole lot –and others treat it more as a job. For those of you in the second camp, you can go back to your drab, meaningless jobs – this post is for the first group. I’m a geek. Not a little bit of a geek, a really big one. I love technology, I get excited about science and electronics in general, and I read math books when I don’t have to. Yes, I have a Star Trek item or two around the house. My daughter is fluent in both Monty Python AND Serenity. I totally admit it. So if you’re like me (OK, maybe a little less geeky than that), then go for it. Put those toys in your cubicle, wear your fan shirt, but most of all, geek up your tools. No, this isn’t an April Fool’s post – I really mean it. I’ve noticed that when I get the larger monitor, better mouse, cooler keyboard, I LIKE coming to work. It’s a way to reward yourself – I’ve even found that it makes work easier if I have the kind of things I enjoy around to work with. So buy that old “clicky” IBM keyboard, get three monitors, and buy a nice headset so that you can set all of your sounds to Monty Python WAV’s. And get to work.

Avoid forgotten events by increasing your memory Have you ever had one of those days where you keep forgetting things? That can happen in Extended Events too; we call it dropped events. In order to optimizes for server performance and help ensure that the Extended Events doesn’t block the server if to drop events that can’t be published to a buffer because the buffer is full. You can determine if events are being dropped from a session by querying the dm_xe_sessions DMV and looking at the dropped_event_count field. Aside: Should you care if you’re dropping events?Maybe not – think about why you’re collecting data in the first place and whether you’re really going to miss a few dropped events. For example, if you’re collecting query duration stats over thousands of executions of a query it won’t make a huge difference to miss a couple executions. Use your best judgment. If you find that your session is dropping events it means that the event buffer is not large enough to handle the volume of events that are being published. There are two ways to address this problem. First, you could collect fewer events – examine you session to see if you are over collecting. Do you need all the actions you’ve specified? Could you apply a predicate to be more specific about when you fire the event? Assuming the session is defined correctly, the next option is to change the MAX_MEMORY option to a larger number. Picking the right event buffer size might take some trial and error, but a good place to start is with the number of dropped events compared to the number you’ve collected. Aside: There are three different behaviors for dropping events that you specify using the EVENT_RETENTION_MODE option. The default is to allow single event loss and you should stick with this setting since it is the best choice for keeping the impact on server performance low.You’ll be tempted to use the setting to not lose any events (NO_EVENT_LOSS) – resist this urge since it can result in blocking on the server. If you’re worried that you’re losing events you should be increasing your event buffer memory as described in this section. Some events are too big to fail A less common reason for dropping an event is when an event is so large that it can’t fit into the event buffer. Even though most events are going to be small, you might find a condition that occasionally generates a very large event. You can determine if your session is dropping large events by looking at the dm_xe_sessions DMV once again, this time check the largest_event_dropped_size. If this value is larger than the size of your event buffer [remember, the size of your event buffer, by default, is max_memory / 3] then you need a large event buffer. To specify a large event buffer you set the MAX_EVENT_SIZE option to a value large enough to fit the largest event dropped based on data from the DMV. When you set this option the Extended Events engine will create two buffers of this size to accommodate these large events. As an added bonus (no extra charge) the large event buffer will also be used to store normal events in the cases where the normal event buffers are all full and waiting to be processed. (Note: This is just a side-effect, not the intended use. If you’re dropping many normal events then you should increase your normal event buffer size.) Partitioning: moving your events to a sub-division Earlier I alluded to the fact that you can configure your event session to use more than the standard three event buffers – this is called partitioning and is controlled by the MEMORY_PARTITION_MODE option. The result of setting this option is fairly easy to explain, but knowing when to use it is a bit more art than science. First the science… You can configure partitioning in three ways: None, Per NUMA Node & Per CPU. This specifies the location where sets of event buffers are created with fairly obvious implication. There are rules we follow for sub-dividing the total memory (specified by MAX_MEMORY) between all the event buffers that are specific to the mode used: None: 3 buffers (fixed)Node: 3 * number_of_nodesCPU: 2.5 * number_of_cpus Here are some examples of what this means for different Node/CPU counts: Configuration None Node CPU 2 CPUs, 1 Node 3 buffers 3 buffers 5 buffers 6 CPUs, 2 Node 3 buffers 6 buffers 15 buffers 40 CPUs, 5 Nodes 3 buffers 15 buffers 100 buffers   Aside: Buffer size on multi-processor computersAs the number of Nodes or CPUs increases, the size of the event buffer gets smaller because the total memory is sub-divided into more pieces. The defaults will hold up to this for a while since each buffer set is holding events only from the Node or CPU that it is associated with, but at some point the buffers will get too small and you’ll either see events being dropped or you’ll get an error when you create your session because you’re below the minimum buffer size. Increase the MAX_MEMORY setting to an appropriate number for the configuration. The most likely reason to start partitioning is going to be related to performance. If you notice that running an event session is impacting the performance of your server beyond a reasonably expected level [Yes, there is a reasonably expected level of work required to collect events.] then partitioning might be an answer. Before you partition you might want to check a few other things: Is your event retention set to NO_EVENT_LOSS and causing blocking? (I told you not to do this.) Consider changing your event loss mode or increasing memory. Are you over collecting and causing more work than necessary? Consider adding predicates to events or removing unnecessary events and actions from your session. Are you writing the file target to the same slow disk that you use for TempDB and your other high activity databases? <kidding> <not really> It’s always worth considering the end to end picture – if you’re writing events to a file you can be impacted by I/O, network; all the usual stuff. Assuming you’ve ruled out the obvious (and not so obvious) issues, there are performance conditions that will be addressed by partitioning. For example, it’s possible to have a successful event session (eg. no dropped events) but still see a performance impact because you have many CPUs all attempting to write to the same free buffer and having to wait in line to finish their work. This is a case where partitioning would relieve the contention between the different CPUs and likely reduce the performance impact cause by the event session. There is no DMV you can check to find these conditions – sorry – that’s where the art comes in. This is  largely a matter of experimentation. On the bright side you probably won’t need to to worry about this level of detail all that often. The performance impact of Extended Events is significantly lower than what you may be used to with SQL Trace. You will likely only care about the impact if you are trying to set up a long running event session that will be part of your everyday workload – sessions used for short term troubleshooting will likely fall into the “reasonably expected impact” category. Hey buddy – I think you forgot something OK, there are two options I didn’t cover: STARTUP_STATE & TRACK_CAUSALITY. If you want your event sessions to start automatically when the server starts, set the STARTUP_STATE option to ON. (Now there is only one option I didn’t cover.) I’m going to leave causality for another post since it’s not really related to session behavior, it’s more about event analysis. - Mike Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!
