  • Understanding Authorized Access to your Google Account

    - by firebush
    I'm having trouble understanding what I'm am granting to sites when they have "Authorized Access to my Google Account." This is how I see what has authorized access: Log into gmail. Click on the link that is my name in the upper-right corner, and from the drop-down select Account. From the list of links to the left, select Security. Click on Edit next to Authorized applications and sites. Authenticate again. At the top of the page, I see a set of sites that have authorized access to my account in various ways. I'm having trouble finding out information about what is being told to me here. There's no "help" link anywhere on the page and my Google searches are coming up unproductive. From the looks of what I see there, Google has access to my Google calendar. I feel comfortable about that, I think. But other sites have authorization to "Sign in using your Google account". My question is, what exactly does that authorization mean? What do the sites that have authorization to "Sign in using my Google account" have the power to do? I hope that this simply means that they authorize using the same criterion that gmail does. I assume that this doesn't grant them the ability to access my email. Can someone please calm my paranoia by describing (or simply pointing me to a site that describes) what these terms mean exactly? Also, if you have any thoughts about the safety of this feature, please share. Thanks!

  • Asus K50I sound issues

    - by MrStatic
    I have an Asus K50IJ (Bestbuy) laptop and have issues with my sound. Speakers themselves work fine but when I plug into the headphone jack it auto mutes the front channel and no sounds comes out of either the speakers or the headphones. If I then unmute the channel I get sound from both the speakers and the headphones. alsamixer shows the Headphone channel as all grayed out. /etc/modprobe.d/alsa-base.conf I have tried snd-hda-intel model="asus-laptop" and snd-hda-intel model="asus" In Sound Preferences I have gone to output and changed the Connector to 'Analog Headphones' that results in no sound from either speakers or headphones. As one forum suggested I tried to comment out blacklist snd_pcsp in the blacklist.conf which resulted in no change. lspci -v shows: 00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03) Subsystem: Santa Cruz Operation Device 1043 Flags: bus master, fast devsel, latency 0, IRQ 45 Memory at fe9f4000 (64-bit, non-prefetchable) [size=16K] Capabilities: [50] Power Management version 2 Capabilities: [60] MSI: Enable+ Count=1/1 Maskable- 64bit+ Capabilities: [70] Express Root Complex Integrated Endpoint, MSI 00 Capabilities: [100] Virtual Channel Capabilities: [130] Root Complex Link Kernel driver in use: HDA Intel Kernel modules: snd-hda-intel

  • DDoS nulling to some ips and other options?

    - by Prix
    I am looking for some information in regards DDoS in the follow scenario: I have a server that is behind a Cisco Guard and it will be DDoS'ed, I only care about a set list of IPS that by not means are the attackers. Is it possible to null all other ips but this list to actually get any response to my server or in the long run no matter what I do if they have enough DDoS power I will just go down like a flie ? Is there any recommended company out there that can actually cope with a DDoS ? My server will mainly run several clients that will get connected to a external server and all it needs access to is my local MySQL the the private network so I can access it. There will be no other services runnings such as web or ftp etc at least not to the external ips of the server if i ever have to have any of these service they will be on the private network. The MySQL will be available externally only to 1 safe ip not known by anyone but me and internally at localhost + private network. Are there any solutions ?

  • Weirdly high ping on direct ethernet connection?

    - by Antriel
    I bought new Lenovo IdeaCentre H430 pc and I'm having problem with high pings. Windows 7 with on-board realtek NIC. Fresh install, fully updated, drivers installed from included CD. When I start pinging router (direct 1Gb ethernet connection, 1 hop), pings start at <1ms (which is fine) and after a while they jump to 300-1000ms. I loaded up live ubuntu to test if the problem might be in HW. It's not, in ubuntu pings were always <1ms. I also noticed that when I start using connection somehow, pings go down to 1ms, but go back up when I stop using it (tested by accessing live camera feed on LAN). Power Options set to max performance. I disabled Interrupt Moderation on the NIC, didn't help. I tested it in the safe mode with networking, same problem there. It slows down our client-server based programs and I have no idea what's causing it. All I could google up was that disabling Interrupt Moderation would help, it didn't though. Anyone had similar problems? tl;nr: Computer is giving high pings to router when idle and normal pings when network is under load, it slows down our software significantly.

  • What was your biggest waste of money, and what should you have bought instead? [closed]

    - by rob
    I waste a lot of money on computer equipment and other electronics that I don't really need. I've also bought software that I've never really used, or which as been replaced by better free software. As I'm buying things, it doesn't seem like much--fifty bucks here, a hundred dollars there. But when I go back and look at how much I've spent over my past few electronics purchases, I usually start to think of the other things I could have bought with that money instead. Most of the computer hardware and electronics don't usually improve my life by much, if at all. Case in point: back when I was in college, I prided myself on getting the best deals for computer hardware, but when I went back and added up all the money I had spent, I had probably wasted close to a thousand dollars on "cheap" $100 hard drives that eventually all went bad (including the warranty replacements). Even if they did still work, it would not be worth the effort to use them, because they're too small and too noisy by today's standards. I've also spent thousands more on other junk, such as RAM and CPU upgrades that only gave modest performance jumps, and wireless audio transmitters that I used for a short time to stream music from the now-defunct Yahoo! Music service. Every time I see a really great deal on RAM or video cards, I come one click away from buying them, but these days I'm usually able to resist. I've been wanting to get into woodworking ever since I moved into my house, and five years later I'm finally saving up for a $600 table saw. Sure, I've already got a toolbox and a couple of the essential power tools like a drill and a jigsaw, but I can't help but think that I'd have an entire shop full of woodworking tools and a lot of nice wood furniture if I hadn't wasted all that money back in college. What has been your biggest waste of money on computer stuff and technology? If you had all that money back, would you make the same mistake again and buy the same types of things, or would you spend it on something else?

  • Wake on LAN Problem

    - by Caley Woods
    I'm working to get wake on lan (wol) working so that we can do some power management at my workplace. I've enabled WOL on a test laptop running Win 7 x64 and put it to sleep and hibernate both with no luck. I'm using a 3rd party utility and I've ran wireshark on the test laptop with it booted up and I can see the WOL packets coming in and the machine refuses to wake from sleep or hibernate. I thought maybe it was the computer I was using so I had another Win 7 x64 laptop nearby and I tried it, same scenario. We're in a cisco environment and I believe I gotten all the pieces in place since I'm seeing the WOL packets come through. I've tested two machines on the same subnet to eliminate the possibility of a misconfiguration on the switch, this also has the same behavior. The laptop models are a Compaq 6510b and 6730b. Is there something I'm missing? I'm trying this across UDP port 50200 since that's the port the actual management system will use after I get it working.

  • XP/Intel wirelss only showing 'hpsetup' ad-hoc network that isn't there

    - by ewall
    Trying to help my friend with her work XP laptop, which recently stopped seeing any wireless SSIDs except the SSID 'hpsetup' (presumably from a wireless-enabled HP printer). Relevant information: The laptop is a Lenovo T500 (Centrino 2 chipset) with XP SP3. The network adapter is Intel WiFi Link 5300 AGN (built-in). The latest version (13.5) of the Intel drivers only are installed, not the Intel config software, so XP is using the Wireless Zero-Config manager. The wireless router is a NetGear WGR614 v7 with 802.11b/g. The SSID is broadcasting, and all the other laptops in the house can see and connect to it. On the laptop, I have tried repairing the network connection, disabling power management, turning off 802.11a & n radio, and more... but it didn't help. Some of the wireless settings are managed by Group Policy from her office (I get the "At least one of your changes was not applied successfully to your wireless configuration" message). It is enforced to connect to "Access point (infrastructure) networks only". The real kicker is that my laptop does not an SSID named 'hpsetup' here, but it can see several broadcasted SSIDs including the one we want, while my friend's laptop doesn't see any SSID except 'hpsetup'. Any suggestions?

  • Best way to troubleshoot intermittent network outages?

    - by Ben Scheirman
    We have a Comcast 50/10 line into our office. We keep seeing very short but sometimes frequent drops in our internet service. It's enough to kick you off of skype and stop any websites from loading, which is obviously affecting our productivity. We've tried 4 different routers, we've tried moving everyone off of wireless and onto wired via a switch and so far nothing has helped. Right now we're on a Cisco SB WRP400-G1 router. Attached to the router is a 16 port switch going to the ports in all of the offices. We've moved to OpenDNS in the case that it was the comcast DNS servers going down. Today we tried putting the modem, router, and switch on a UPS to make sure it wasn't power fluctuations that was causing it. Every time we call Comcast, by the time they are here the internet is working fine. I'd like to somehow prove that the problem is with Comcast, so if that means plugging in a machine directly into their router and collecting data all day, I'm up for that. I just want to hear ideas on what tools to run and how to collect this data. I could just continuously ping google.com all day long but I'm not sure how valuable that data would be. Thoughts?

  • WOL doesn't work if set to anything other than `a` but this setting makes it boot all the time

    - by Elton Carvalho
    I manage a small "cluster" of 4 Xeon machines with Intel boards in my lab. They are all plugged to a 5-port 3-Com switch with static IP addresses like 10.0.0.x. They are all running OpenSuse 11.4 and their /home/ is served by one of the machines (node00) via NFS. They are plugged to an UPS that can keep them on for ca. 15 minutes, but there are lots of electric shortages due to "unscheduled maintenace" that are longer than this. So they end up being powered down without notice. If I set the BIOS to turn them on after power shortages, the issue is that they all boot at the same time and, if node00 decides to run fsck in the /home/ partition, it does not finish booting before the others try to NFS mount their /home/. I am trying to make wake on lan work, so I can choose to boot the NFS clients only after the server has successfully booted. The problem is that when I run ethtool I get an output like this: Supports Wake-on: pumbag Wake-on: g Theoretically, it is set to wake on MagicPacket(tm), according to the manual. But sending the WOL packet using wol -i 10.0.0.255 $MACADDR does not wake up the box after I shut it down with halt. The ethernet link led blinks after I send the packet, so it appears to be getting to the machine. However, if I set it up with ethtool -s eth1 wol bag, the machine always wakes up right after halting, even if I don't send the Magic packet. This means that the device can wake up with LAN activity, but seems to be ignoring the magic packet. Setting wol ag does not wake the box with the MagicPacket. Does setting wol a mean that it should boot with any broadcast message? How can I diagnose the issue of the machine not waking up with the MagicPacket even though I am sending it and it's set up to wake up with it? Thanks in advance!

  • "Can't find root filesystem / error mounting /dev/root" when booting to new kernel

    - by salparadise
    I am trying to upgrade my kernel from 2.6.18-274 to 2.6.39 for some wireless card drivers. When I boot into the new kernel I get the "Can't find root filesystem / error mounting /dev/root" googling led me to this page http://fedoraproject.org/wiki/Common_kernel_problems#Can.27t_find_root_filesystem_.2F_error_mounting_.2Fdev.2Froot From what I am reading seems to be an issue with a driver for my SATA controller or HD, but I can't find what option I need to add to the kernel. Doing a diff from the old initrd to the new one gives me the following: root-> diff /tmp/kafter /tmp/kbefore 6a7,8 > lib/dm-message.ko > lib/dm-region_hash.ko 8a11 > lib/dm-raid45.ko 13d15 < lib/dm-region-hash.ko 16a19 > lib/dm-mem-cache.ko Do I need any of those? not sure if I would need dm-raid45.ko as I am not running a raid.

  • HTTP request hangs for for exactly 150 seconds, then gives incomplete response. How do I find out wh

    - by Nathan
    I am hosting a Wordpress blog, and having a strange problem. When I connect to the server (http://71.65.199.125/ at the time of this writing) it displays the Title correctly, and half of a download bar, indicating it has received some of the page, then it hangs for exactly 150 seconds (timed it twice), then it sends the rest of the page, but without the stylesheet. after that it hangs indefinitely, continuing to say "connecting..." without making any progress. If you have any clues as to what might be happening, or how I could print debug logs of PHP or something to see what it is looking for during that hang time that would probably help. recent changed I have made: switched wordpress themes, however I did see it work once with the new theme. moved the server to another building, with an identical ISP, and linksys router forwarding setup. I have also added a favicon.gif file to /var/www but without linking to it from any of the wordpress pages. I have also had a unanticipated power interruption. System info: Ubuntu debian 9.04 Apache2 PHP 5 Wordpress 2.9.2 Thank you

  • Alternative Bluetooth Stacks for Windows 7 64bit

    - by Martin
    I have a notebook with an inbuilt Broadcom BCM2046 bluetooth adapter and several bluetooth HID-devices (mice, keyboards etc.) The operating system is Windows 7 64 bit Professional. The HID-devices all work perfectly with other computers, but on the system mentionend above, problems with some power-saving features inside the HID-devices occur (see eg. Amazon reviews for Microsoft Mobile Keyboard 6000 not waking up). I have tried the bluetooth drivers supplied by Windows update and the latest Broadcom drivers directly from the Broadcom updater software. The problems persist (I can rule out any further configuration issues or alternative device drivers, I have tried every possibility). I have tried a trial version of the BlueSoleil Bluetooth stack and it solved the wake-up problem. However the BlueSoleil stack causes some other problems, is relatively expensive and I would prefer not to use it. My question: are there any other alternative bluetooth stacks availible for Windows 7 64bit? To my knowledge there used to be Toshiba Bluetooth stack for non-Toshiba hardware, but the older versions I have found on the internet do not install, they do not seem to recognize the bluetooth hardware when installing the driver.

  • Compaq Motherboard gives "CPU Fan Error"

    - by John
    I have a motherboard for a HP business desktop dx5150 PC. The model written on the board is "MS-7050" and it is for an AMD socket 939 processor. I got everything installed in it, and when I turned it on, it showed a message stating that there was a "CPU Fan Error" (or some similar language) and then turned off. It never stays on for more than about 30 seconds, probably less. The fan had previously been working great, but I replaced it anyway with a brand new Cooler Master fan. This did not work. I then reset the BIOS with the jumpers on the board, no dice. I replaced the CMOS battery. Same error. I then replaced the entire computer power supply with a brand new Antec, same error. The fan header is keyed, and has room for 3 pins. The CPU fan is designed the same way, so its not that I'm missing a temperature sensor or anything. Can anyone give some suggestions? Especially maybe some secret keystrokes to bypass this error?

  • How can something relevant to graphics completely kill a motherboard?

    - by leladax
    I was coding something in OpenGL and after a bug there was an 'OS slowed down' situation. After a few seconds the screen went blank and the laptop shutdown. Now not even a led turns on battery or not. It doesn't appear to be the AC or the battery since there was some battery when it died and when it's connected to the AC the laptop produces near the AC connection a very slight 'clicking' noise (very faint, one has to be very careful to notice it, I don't know if it was there forever tbh). I suspect the motherboard died, as in something from the point it gets AC or battery power and the point it actually feeds itself. But I can't figure out how that effect was produced by the OpenGL bug or graphics overheating. If the graphics died alone, it should at least give some indication that the laptop is barely alive, at least a led, a sound, anything, the laptop is instead completely dead (other than faint 'clicking' I mentioned). Does anyone have expert advice on this? I'm especially interested in any ideas connected to "graphics overheated/bugged ---- they killed motherboard". I have a very lengthy experience in that stuff as a hobbyist and it really puzzles me. It's not just a "AC died" situation I can easily google.

  • Adding Windows 7 32 bit as dual boot option

    - by djerry
    A relative of mine has bought a new laptop this year on which windows 7 (64 bit) is installed. Aside some standard programs he uses on that laptop, he also has some software for his bike that needs to run. The developers of that program still don't support 64-bit systems and therefor I thought about making it dual boot, so he can still use the power of the 64-bit, and just for the bike program, he can initiate the 32-bit version. My questions now are: What are the risks involved in this operation? What steps need to be taken to make this dual boot succesful? Any other ideas besides dual booting? Thanks in advance. Edit I might have forgotten/misphrased something. The software does run on 64-bit, but it cannot find the bike connected to the computer. So I think it's a matter drivers which aren't compatible with the 64-bit system. That's why I wanted to install the 32-bit windows so the drivers would work.

  • Windows 7 ignores F6/F8 and will not boot

    - by P.Brian.Mackey
    I have a work PC with sophos safeguard encryption on it. Windows failed to start. When I bootup I receive an error saying a recent hardware or software change might be the cause. File: \Boot\BCD Status: 0xc0000098 Info: The windows boot configuration data file does not contain a valid OS entry. This began after the PC forced me to run a system recovery. My machine had powered down improperly (power outage?) and simply would not respond to my keyboard input to cancel the option to scan my system. After the scan "repaired" a boot file, my system crashed. Now it tells me I can insert my windows 7 disk and run recovery. I can't simply do this because of Safeguard. The system recovery can't see my encrypted drive. I tried hitting F2 to manually login to Safeguard and then selected the option to boot from media. The computer prompts me to hit any key to boot from disk...which I do, but once again it is not reading my keyboard input. I can't get F8/F6 to bypass startup files and get me to a command prompt like the old days. If I could get to a command prompt I might could recover the file windows jacked up from its backup location...though I may need to use the windows recovery disk UI to do this..??? In the past I've been able to slap in a PS/2 keyboard when the USB keyboards stop responding like this. I have no PS/2 keyboard available. Anyone have any idea how I can undo the damage windows system recovery has done with safeguard installed?

  • Why isn't my phone charging with some micro usb cables?

    - by Jacxel
    I ordered 3 microUSB cables over ebay. My phone was at about 50% battery and I wanted to use it as a hot spot for some browsing on my laptop, so I plugged it in, a charging icon appeared on the phone, my laptop showed it as a connected usb device and so I went about my business. About 30 minutes later I checked the phone and to my dismay saw 45% battery. But ahh, I thought, I have been putting the poor little thing under too much pressure, acting as a WiFi hotspot must drain the battery quicker than it can charge via usb, perhaps even using my laptops usb port wouldn't output enough power. Unscathed I continued on and when I was going to bed I plugged the usb cable into a mains adapter and switched everything battery consuming off and content, went to sleep. The next morning I was awoken by my phones alarm which got cut off unexpectedly. I attempted to unlock my phone which showed no more signs of life. Why isn't my phone charging with these new USB cables? For clarity: They transfer data with no problems The phone appears to be charging, showing all the signs and lights it normally would, the cable that came with the phone works as you would expect, so its not a fault with the phone, I think they slow the discharging of the phone, but I could be wrong. Are these just bad quality cables? Is there a way to fix this issue?

  • All network devices freezing when Airport Extreme Base Station is connected. Any ideas?

    - by Jon
    I've been troubleshooting this issue for a while, and through a series of events have it narrowed down to my airport extreme base station. I like this router, since I'm able to connect to IPV6 sites without any insane configuration (my alternate router is too old and doesn't support v6). My question is: Has anyone else had this issue, if so how is it resolved? If not, can you recommend a good IPv6 router? Here is how I came to the conclusion that it is the router: Devices: XBOX 360, HTC Incredible, Home-Built machine running FreeBSD, Home-Built machine running Ubuntu 10.04. 1.) Noticed freezing on Ubuntu Box. 2.) Noticed freezing on XBOX360 3.) Noticed freezing on HTC Incredible (only when connected to my network wirelessly). The above all happened at random times throughout the past few weeks. Over the last few days, I was playing XBOX and noticed that the XBOX and Ubuntu machines both froze. I picked up my phone, and it was also frozen. I reset all devices, power-cycled my router, and all was fine again. About two hours later, it happened again (I was playing Forza III, the XBOX froze; I went to the Ubuntu box and it was frozen; unfortunately, the HTC phone was not connected wirelessly, and the FreeBSD box was turned off). I can't even begin to imaging what a router could be doing to freeze devices with such differing hardware/software/OS, and I feel absurd for coming to this conclusion, but I have nothing else. I hooked up my archaic Netgear router, and have had no problems since. :(

  • Improve wireless performance

    - by djechelon
    Hello, I have a Trust Speedshare Turbo Pro router, which is running on channel 6. I found that the wireless signal (and network performance) dramatically drops from my PDA (I can barely attach to the network, even if I set the PDA's energy settings to maximum wireless performance) when I even exit my room, and I don't have shielded walls or something like that. I can't even stream a SD video from my desktop (connected via LAN) to my laptop using WiFi, while via LAN it works fine. I read that changing router's channel could improve performance due to interference reducing. I found that almost all wireless networks around here run on channels 6 and 11. I tried to go to my router's settings page to change channel, but I found that the combo box only allows me to select 6!! I'm not sure, but I may have been able in the past to change channel, though not to all of the available channels. A few minutes ago I tried a firmware upgrade, but it didn't solve my problem. My question is Is it possible that my router is someway locked to its channel? I bought it on my own, I didn't receive it from my ISP Apart from boosting the antenna power to the maximum (which, by the way, increases the EM radiation my and my family's bodies absorb 24/7 and is little more environment-unfriendly), do you have any tips on getting high quality transmission up to 5 metres from the antenna? Thank you

  • Mac mini simple customized, Mac mini server or other?

    - by microspino
    I'm in front of a big IT choice for my little office and I need some advice. We have 5 users, 1 super user, 1 HP500 DesignJet Plotter, other 4 laser printers, 1 HP Fax/Print/Scan/Copy machine. All the clients are XP Sp3 boxes. We would like to: centralize and share 90Gb of files using a Dropbox (this way we will have LAN sync of local working directories + internet backup + access our files wherever we are). centralize our plotter, printers and fax machine backup all the workstations share outlook calendar and tasks run 24x7 saving some energy Of course this setup It's just the first step to a more serious and creative network management of our office, so we are open to new ideas. The budget vary from 400€ to 900€, we are not tech gurus but at least one of us is a power user close to become a geek. I've read some articles on macminicolo about a mac mini either normal or with snow leopard server. I heard about Windows Home Server too on the lifehacker website but I'm in a sort of analysis - paralysis can You help me?

  • Rebuilding LVM after RAID recovery

    - by Xiong Chiamiov
    I have 4 disks RAID-5ed to create md0, and another 4 disks RAID-5ed to create md1. These are then combined via LVM to create one partition. There was a power outage while I was gone, and when I got back, it looked like one of the disks in md1 was out of sync - mdadm kept claiming that it only could find 3 of the 4 drives. The only thing I could do to get anything to happen was to use mdadm --create on those four disks, then let it rebuild the array. This seemed like a bad idea to me, but none of the stuff I had was critical (although it'd take a while to get it all back), and a thread somewhere claimed that this would fix things. If this trashed all of my data, then I suppose you can stop reading and just tell me that. After waiting four hours for the array to rebuild, md1 looked fine (I guess), but the lvm was complaining about not being able to find a device with the correct UUID, presumably because md1 changed UUIDs. I used the pvcreate and vgcfgrestore commands as documented here. Attempting to run an lvchange -a y on it, however, gives me a resume ioctl failed message. Is there any hope for me to recover my data, or have I completely mucked it up?

  • Looking to get a small server – need web, PHP, PostgreSQL.

    - by Javawag
    Hi all! I'm looking to get a cheap (low end) server to serve web pages (xHTML/PHP), but I also need to be able to set up PostGreSQL on the system too. Ideally the server would have low power consumption, run Linux (I prefer Mac OS X but a Mac Mini, although the size I'm looking for, is too much money!) and be around £100 (~$160US). EDIT: Just to make it clearer, I'm looking to purchase the server hardware myself – but I want something about Mac Mini sized. I don't want to pay for hosting! Also, quick question – if it's to serve web pages from my home (standard ISP connection, no static IP!), what do I need in place to get this working. I'm guessing I would sign up with some service like no-ip, and register a domain to point to my no-ip address (then install the no-ip software on the server to update that with the current IP). I know the idea of running a server behind a normal ISP connection isn't very elegant, but I'd prefer to have the server where I can see it then pay over the odds for a hosting service where I have little to no control over what happens. Also, I could write my own server software for apps/etc to connect to as well. Anyways I'm rambling! What do you guys think?! Javawag

  • Pivot Table grand total across columns

    - by Jon
    I'm using Excel 2010 and Power Pivot. I'm trying to calculate confidence and velocity for a development team. I'm extracting some information from our time and defect system each day and building a data set. What I need to do with Excel is do the calculations. So each day I add to my data set 1 row per task in the current project, estimate for that task and the time spent on that task. What I want to calculate is the estimate/actual for each task but also for each person. The trouble is that each day the actual is cumulative so I need to pick out the maximum value for each task. The estimate should remain unchanged. I can make this work at the task level with a calculated measure (=MAX(worked)/MAX(estimate)) but I don't know how to total this up for a person. I need the sum of the max worked for each task. So a dataset might look like: Name Task Estimate Worked N1 T1 3 1 N2 T2 3 1 N3 T3 4 1 N1 T1 3 2 N2 T4 5 1 N3 T3 4 2 N1 T5 1 2 N2 T6 2 3 N3 T7 3 2 What I want to see is for task T1 2 days were worked against an estimate of 3 days - so 2/3. For person N1 I want to see that they worked a total of 4 days against an estimate of 4 days so 4/4. For person N2 they worked 5 days for an estimate of 10 days. Any ideas on how I can achieve this?

  • why is Mac OSX Lion losing login/network credentials?

    - by Larry Kyrala
    (moved from stackoverflow...) Symptoms So at work we have OSX 10.7.3 installed and every once in a while I will see the following behaviors: 1) if the screen is locked, then multiple tries of the same user/pass are not accepted. 2) if the screen is unlocked, then opening a new bash term may yield prompts such as: `I have no name$` or lkyrala$ ssh lkyrala@ah-lkyrala2u You don't exist, go away! Even when our macs are working normally, everyone here has to login twice. The first time after boot always fails, but the second time (with the same password, not changing anything, just pressing enter again) succeeds. Weird? Workarounds There are some workarounds that resolve the immediate problem, but don't prevent it from happening again: a) wait (maybe an hour or two) and the problems sometimes go away by themselves. b) kill 'opendirectoryd' and let it restart. (from https://discussions.apple.com/thread/3663559) c) hold the power button to reset the computer Discussion Now, the evidence above points me to something screwy with opendirectory and login credentials. Some other people report having these login problems, but it's hard to determine where the actual problem is (Mac, or network environment?). I should add that most of the network are Windows machines, but we have quite a few Macs and Linux machines as well, but I'm not sure of the details of how the network auth is mapped from various domains to others... all I know is that our network credentials work in Windows domains as well as mac and linux logins -- so something is connecting separate systems, or using the same global auth system.
