• Battery management of a Macbook

  - by darthvader

  I bought a Macbook Pro last week. I mostly use (and plan to use) it like a desktop with an external monitor. I use the system at least 15 hours a day. Now using the coconut battery application, I figured out that the capacity has the current capacity has reduced to 98% of the design capacity. I was wondering what is the best way to manage battery. Should it be always either charging or discharging Should it be plugged in all time. I barely get 2 hours and 30 minutes on battery. Is that normal? I run XCode, VMWare Fusion (for Visual Studio), Mail app, Chrome (5-10 tabs) and Itunes (mp3). The brightness is 60% on battery. I already did the calibration.

• Looking for Light Time Management Software Suggestions (for Mac)

  - by tmo256

  I'm looking for a simple project management app that performs task scheduling, along the line of Merlin or MS Project, but no where near as robustly. I don't need to deal with other (human) resources, but I work on anything from 3 to 6 different projects at a time. What I'd like is to be able to input deadlines and tasks, and have a schedule suggested to complete them. I do technical work, but I don't think I need anything specifically for software development, especially considering I do plenty of other kinds of things, like graphic design and social media PR. I'd really like this to be dead simple, as simple as possible. Suggestions? OmniPlan, something web-based? Definitely cannot afford anything too extravagant, really looking for something under $200. Thanks for your input!

• How could I safely fix my walking "dead pixel" bug?

  - by Cawas

  I need suggestions. I've got a live little bug inside my macbook pro screen for 2 days now. I've tried to film it using my iPhone, but it ain't that good. :( Should I try to open it? o_O C'mon, looking for ideas here! :) edit: Here's an alike video. It's not moving anymore for now... I hope it isn't dead! Right when I've found a possible solution along with many ideas on that link: suction cup; monitor off and lamp on to attract it out; scratching the screen (made it move a little); and got to know there's no warranty for this "feature" (also known as bad design in a jargon). edit2: It's been "fixed" on its own. Just check the answer.

• Creating Persistent Drive Labels With UDEV Using /dev/disk/by-path

  - by Matt

  I have a new BackBlaze Pod (BackBlaze Pod 2.0). It has 45 3TB drives and they when I first set it up they were labeled /dev/sda through /dev/sdz and /dev/sdaa through /dev/sdas. I used mdadm to setup three really big 15 drive RAID6 arrays. However, since first setup a few weeks ago I had a couple of the hard drives fail on me. I've replaced them but now the arrays are complaining because they can't find the missing drives. When I list the the disks... ls -l /dev/sd* I see that /dev/sda /dev/sdf /dev/sdk /dev/sdp no longer appear and now there are 4 new ones... /dev/sdau /dev/sdav /dev/sdaw /dev/sdax I also just found that I can do this... ls -l /dev/disk/by-path/ total 0 lrwxrwxrwx 1 root root 10 Sep 19 18:08 pci-0000:02:04.0-scsi-0:0:0:0 -> ../../sdau lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:02:04.0-scsi-0:1:0:0 -> ../../sdb lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:02:04.0-scsi-0:2:0:0 -> ../../sdc lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:02:04.0-scsi-0:3:0:0 -> ../../sdd lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:02:04.0-scsi-0:4:0:0 -> ../../sde lrwxrwxrwx 1 root root 10 Sep 19 18:08 pci-0000:02:04.0-scsi-2:0:0:0 -> ../../sdae lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:02:04.0-scsi-2:1:0:0 -> ../../sdg lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:02:04.0-scsi-2:2:0:0 -> ../../sdh lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:02:04.0-scsi-2:3:0:0 -> ../../sdi lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:02:04.0-scsi-2:4:0:0 -> ../../sdj lrwxrwxrwx 1 root root 10 Sep 19 18:08 pci-0000:02:04.0-scsi-3:0:0:0 -> ../../sdav lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:02:04.0-scsi-3:1:0:0 -> ../../sdl lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:02:04.0-scsi-3:2:0:0 -> ../../sdm lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:02:04.0-scsi-3:3:0:0 -> ../../sdn lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:02:04.0-scsi-3:4:0:0 -> ../../sdo lrwxrwxrwx 1 root root 10 Sep 19 18:08 pci-0000:04:04.0-scsi-0:0:0:0 -> ../../sdax lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:04:04.0-scsi-0:1:0:0 -> ../../sdq lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:04:04.0-scsi-0:2:0:0 -> ../../sdr lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:04:04.0-scsi-0:3:0:0 -> ../../sds lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:04:04.0-scsi-0:4:0:0 -> ../../sdt lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:04:04.0-scsi-2:0:0:0 -> ../../sdu lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:04:04.0-scsi-2:1:0:0 -> ../../sdv lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:04:04.0-scsi-2:2:0:0 -> ../../sdw lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:04:04.0-scsi-2:3:0:0 -> ../../sdx lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:04:04.0-scsi-2:4:0:0 -> ../../sdy lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:04:04.0-scsi-3:0:0:0 -> ../../sdz I didn't list them all....you can see the problem above. They're sorted by scsi id here but sda is missing...replaced by sdau...etc... So obviously the arrays are complaining. Is it possible to get Linux to reread the drive labels in the correct order or am I screwed? My initial design with 15 drive arrays is not ideal. With 3TB drives the rebuild times were taking 3 or 4 days....maybe more. I'm scrapping the whole design and I think I am going to go with 6 x 7 RAID5 disk arrays and 3 hot spares to make the arrays a bit easier to manage and shorten the rebuild times. But I'd like to clean up the drive labels so they aren't out of order. I haven't figured out how to do this yet. Does anyone know how to get this straightened out? Thanks, Matt

• Does the retina MacBook Pro Australian charger duckhead have 3 prongs on it or 2?

  - by frenchglen

  I notice that with my Retina MacBook Pro (bought in UK), its charger uses all three prongs to power the laptop (like this, rather than this). Not surprised, it's a powerful machine. I'm going to Australia now and I want to use an aussie duckhead and make use of the innovative design. I have an existing one from an old iPod (and it used to work with fine with my Macbook Air when in australia), but it's only two prongs (like this). Is that enough to power my rMBP? Or will it damage/strain it and I need to find a 3 prong one (if it even exists - I haven't bought my MBP in Australia) like this? Thanks

• How does a trackball reduce pain caused by RSI? [closed]

  - by gunbuster363

  I developed RSI (Repetitive Strain Injury) in my index fingers due excessive mouse clicking. I might consider a trackball as many people suggested. But how does trackball help? I can see it get 2 buttons and a ball which require some fingers to operate on. Will I RSI while I click on the buttons with other healthy fingers? Logitech TrackMan Wheel: I highly doubt this trackball, I assume we are still using the index and middle finger for clicking. Logitech Marble Mouse: I think we will use the thumb to click the left button, will I develop RSI on my thumb? And the right button, which finger should I use? If you know other trackball which might help, please tell me which is the design that help to avoid the stress.

• Any way to fix alphabetical selection behavior in list widgets in Windows?

  - by KP

  In every version of Windows I've ever used (95 through Vista), the following apparent bug has been present in every list widget, whether drop-down, multi-select, or Explorer folder view: If you use the keyboard to select some item alphabetically, the selection gets "locked" on that item. If I have a list with the contents below, and I press D, then Delta will get selected. At this point, pressing A, B, or G will do nothing unless I first switch focus to another window or control, or remove focus by pressing Esc. If, at the beginning, I press G, then I can keep pressing G to cycle through the Gamma entries, but A, B, or D will do nothing unless I clear the focus. Alpha Beta Beta2 Delta Gamma Gamma2 Gamma3 I don't think I've seen this aggravating behavior on OS X, KDE, or Gnome shells, and I can't imagine why this behavior would be "by design." Does anyone know anything about this bug or how to get around it?

• Distributed file systems

  - by Neeraj

  I need to implement a distributed storage system for a set of nodes(devices) connected in a mesh network. So what basically my design goals are: The storage system should be capable of handling dynamic entry and exit of nodes. Replication (for fault tolerance). For this i am thinking of using a Distributed file system. Every node could access data in the other nodes in a transparent manner. Are there some simple, easily pluggable opensource implementations? Thanks for your thoughts!

• Wall jacks to patch panel?

  - by rj454me

  OK, I'm by no means a seasoned networking pro and I had no say so in the design of our current server room which is in dire need of an extreme makeover. Basically, in our server room we have 12 wall plates with 4 RJ-45 ports on each - 48 total RJ-45 ports. From these 48 ports is a spaghetti bowl of network cables feeding our servers located in a rack - there is no patch panel currently, just straight from the wall jack to each server. What I was wondering is, is it feasible to mount a 48 port patch panel in our server rack and feed into this patch panel from the wall jacks (of course nicely routing this cable through some new cable trays)? We really don't have the funds to mount the patch panel and have it fed directly from the switches in the telcom closet which is several hundred feet away. Current: Switch (Telcom Closet) - Wall Jacks - Servers Proposed: Switch (Telcom Closet) - Wall Jacks - Patch Panel - Servers

• Photoshop CS4 slowing down, need advice to improve speed.

  - by Pennf0lio

  Hi, I just recently experienced problem with my Photoshop, It seem that it is slowing down when I am doing graphics design. Big or small files ( from 20 x 20 inch 300 dpi of resolution to 800x600 72 resolution ) it is really slowing down. Particularly when I am panning to my project It just get stuck for a few seconds then back to normal with slow movement. Can you guess what's wrong? I have an updated antivirus and I don't think virus is causing it. other adobe suite is working fine just my photoshop. I am running in windows 7, using Intel Core2 Duo 2.40 Ghz and has an Installed Ram of 2 GB. My primary scratch disk has 21 Gigabyte left and the secondary has a 13.89 GB. I need a solution urgently. I am planning to reformat my computer just to resolve my problem.

• Is an Intel Atom D525 suitable to run MythTV

  - by Martin Thompson

  I have an oldish netbook with an Atom N450 (1.6GHz, 512KB cache) - I've been using it to experiment with MythTV, but it seems really slow, even just to work through the menus! Seconds, sometimes 10 or 20s, to load a new menu. Admittedly from a remote backend, but my older Core1 based laptop seems to be fine with the same setup. I was hoping to use one of the so-called "nettop" devices which currently seem to be D525-based (1.8GHz, 1MB cache) - is double the cache really going to make that much difference? Or has the internal architecture of the Atom moved on leaps and bounds in between? Given that I design non-Intel embedded computers for a living I was hoping to get lots of hardcore architecture detail from the Intel website, so I could see for myself, but I can't find it! So: will a D525 be fast enough to run a MythTV backend/frontend combined box?

• Forcing Remote machine to serve RDP (or similar) session

  - by sMaN

  Due to a Dell/Nvidia design flaw in the Dell Inspiron 1420 series, my laptop no longer shows a display. I am looking for a solution to view it remotely. I have used it via RDP in the past (not for a year though) however for what ever reason I can no longer RDP, it could have been disabled some how. However, I'm on the same LAN, I can ping it, and know its login creditials. Is there a way I can hack into it remotely to force it to serve a RDP session or an alternative? Please bear in mind my only view I could have to its interface is via a remote session. Its running Windows 7 Pro

• How can I create and add a new slide type to the New Slide menu in PowerPoint?

  - by ObligatoryMoniker

  On the Home ribbon in Power Point 2007 there is a new slide button with an arrow that shows you various types of slides that you can add to your presentation: Title Slide, Title and Content, Comparison, Title Only, etc. I want to design a new type of slide that has 4 content areas instead of two and then be able to add new slides of this type using the new slide menu. I know that I can add new Power Point templates but that would require me to start a new presentation with my custom slide type in it and the copy and paste that slide into the current presentation that I am already working on. How can I create a new slide type and then add it to the menu so that I can quickly create new slides of my new 4 content area slide type?

• Color Calibrate Dual Monitor XP SP2

  - by Laramie

  This topic has been touched on before but not really answered. I have a dual monitor system and the colors differ wildly. I currently live Buenos Aires where color correction hardware costs premium prices. I do some graphic design, but don't require a pro-level calibration. That said, I'd like my monitors to be set as close to "true color" as possible. I've located the useful and free Monitor Calibration Wizard, but it seems to adjust the entire system internally at startup. I could use the Microsoft Color Control Panel Applet to set a different ICC or ICM profile for each monitor, but the Monitor Calibration Wizard outputs its own format for profiles.

• Is there a usable HTML web gallery template for Lightroom 2?

  - by Johannes Rössel

  The built-in HTML gallery unfortunately generates invalid HTML markup so its looks are likely more coincidence than proper design. That aside its JavaScript usage prevents using the middle mouse button to open an image in a new tab. A look at the few free HTML gallery templates out there shows me that there seems to be little interest in building an actual HTML gallery which doesn't use JavaScript. Most of them are using JS to build fancy animations or in-page popup boxes containing the image. This may be nice for some people but at least one person who looks at my images is on dial-up and quickly opening all images in individual tabs to let them load and then close the connection is very nice to have there. Anyone seen such a gallery template; i. e. simple, plain HTML without JS? My HTML/CSS skills aren't that good that I can develop such a thing on my own, unfortunately.

• Control truetype font tracking in fontforge

  - by ??O?????

  Hello. I'm designing a font intended to be used mainly as a subtitle font. It's a sans-serif font not unlike Helvetica. The em size is 2000 (I know it "should" be 2048 for a truetype font), the ascent/descent are 1600/400. Most glyphs don't go higher than 1450 though, with the exception of accented Latin characters. There lies the issue: when my font includes accented Latin characters, the tracking (line -of-text intradistance, but correct me if I got the term "tracking" wrong) skyrockets. I can't seem to find a way to control that. As my intended design goes, I don't mind if I have a descender (e.g. "g") above and an accented capital Latin letter below and they almost touch. It's something that does not happen very often, anyway. How can I control tracking? It seems it's auto-calculated.

• Free Cloud Mind Map Solution

  - by Zekta Chan

  As a Software Engineer we had a lot of discussion on SE design. Although we sync every document on the development process on Google Doc, mind map just didn’t fit in Google doc yet. The best we can do is to store a copy and share it online. To me, Mind map is an ir-replaceable piece of tools (yet) as agile note taking tools. And an eFormat is even greater than a paper one, due to the portability and extensibility. Does anyone have a good solution on “cloud-sharing” mind map? (We are using FreeMind at the moment) Thanks

• How to run a DHCP service on Windows 7 Home

  - by Joshua Lim

  I'm trying to setup a DHCP server on Windows 7 Home, tried using a couple of freeware which I found on the Internet but none seemed to work. What I did: On the Windows 7 machine which I install the DHCP Server with the range 192.168.1.12-192.168.1.256.

• Windows Server 2008 R2 network adapter stops working, requires hard reboot

  - by Geoff Dalgas

  TL;DR version: Turns out this was a Windows Server 2008 R2 kernel networking bug. After siccing Microsoft support on it, we (eventually) got an unpublished kernel hotfix from Microsoft to address it. If you, too, are experiencing mysterious low-level network driver failures requiring a reboot/bluescreen cycle, you might want that hotfix (or maybe Service Pack 1 whenever it is released, too.) We have been using HAProxy along with heartbeat from the Linux-HA project. We are using two linux instances to provide a failover. Each server has with their own public IP and a single IP which is shared between the two using a virtual interface (eth1:1) at IP: 69.59.196.211 The virtual interface (eth1:1) IP 69.59.196.211 is configured as the gateway for the windows servers behind them and we use ip_forwarding to route traffic. We are experiencing an occasional network outage on one of our windows servers behind our linux gateways. HAProxy will detect the server is offline which we can verify by remoting to the failed server and attempting to ping the gateway: Pinging 69.59.196.211 with 32 bytes of data: Reply from 69.59.196.220: Destination host unreachable. Running arp -a on this failed server shows that there is no entry for the gateway address (69.59.196.211): Interface: 69.59.196.220 --- 0xa Internet Address Physical Address Type 69.59.196.161 00-26-88-63-c7-80 dynamic 69.59.196.210 00-15-5d-0a-3e-0e dynamic 69.59.196.212 00-21-5e-4d-45-c9 dynamic 69.59.196.213 00-15-5d-00-b2-0d dynamic 69.59.196.215 00-21-5e-4d-61-1a dynamic 69.59.196.217 00-21-5e-4d-2c-e8 dynamic 69.59.196.219 00-21-5e-4d-38-e5 dynamic 69.59.196.221 00-15-5d-00-b2-0d dynamic 69.59.196.222 00-15-5d-0a-3e-09 dynamic 69.59.196.223 ff-ff-ff-ff-ff-ff static 224.0.0.22 01-00-5e-00-00-16 static 224.0.0.252 01-00-5e-00-00-fc static 225.0.0.1 01-00-5e-00-00-01 static On our linux gateway instances arp -a shows: peak-colo-196-220.peak.org (69.59.196.220) at <incomplete> on eth1 stackoverflow.com (69.59.196.212) at 00:21:5e:4d:45:c9 [ether] on eth1 peak-colo-196-215.peak.org (69.59.196.215) at 00:21:5e:4d:61:1a [ether] on eth1 peak-colo-196-219.peak.org (69.59.196.219) at 00:21:5e:4d:38:e5 [ether] on eth1 peak-colo-196-222.peak.org (69.59.196.222) at 00:15:5d:0a:3e:09 [ether] on eth1 peak-colo-196-209.peak.org (69.59.196.209) at 00:26:88:63:c7:80 [ether] on eth1 peak-colo-196-217.peak.org (69.59.196.217) at 00:21:5e:4d:2c:e8 [ether] on eth1 Why would arp occasionally set the entry for this failed server as <incomplete>? Should we be defining our arp entries statically? I've always left arp alone since it works 99% of the time, but in this one instance it appears to be failing. Are there any additional troubleshooting steps we can take help resolve this issue? THINGS WE HAVE TRIED I added a static arp entry for testing on one of the linux gateways which still didn't help. root@haproxy2:~# arp -a peak-colo-196-215.peak.org (69.59.196.215) at 00:21:5e:4d:61:1a [ether] on eth1 peak-colo-196-221.peak.org (69.59.196.221) at 00:15:5d:00:b2:0d [ether] on eth1 stackoverflow.com (69.59.196.212) at 00:21:5e:4d:45:c9 [ether] on eth1 peak-colo-196-219.peak.org (69.59.196.219) at 00:21:5e:4d:38:e5 [ether] on eth1 peak-colo-196-209.peak.org (69.59.196.209) at 00:26:88:63:c7:80 [ether] on eth1 peak-colo-196-217.peak.org (69.59.196.217) at 00:21:5e:4d:2c:e8 [ether] on eth1 peak-colo-196-220.peak.org (69.59.196.220) at 00:21:5e:4d:30:8d [ether] PERM on eth1 root@haproxy2:~# arp -i eth1 -s 69.59.196.220 00:21:5e:4d:30:8d root@haproxy2:~# ping 69.59.196.220 PING 69.59.196.220 (69.59.196.220) 56(84) bytes of data. --- 69.59.196.220 ping statistics --- 7 packets transmitted, 0 received, 100% packet loss, time 6006ms Rebooting the windows web server solves this issue temporarily with no other changes to the network but our experience shows this issue will come back. Swapping network cards and switches I noticed the link light on the port of the switch for the failed windows server was running at 100Mb instead of 1Gb on the failed interface. I moved the cable to several other open ports and the link indicated 100Mb for each port that I tried. I also swapped the cable with the same result. I tried changing the properties of the network card in windows and the server locked up and required a hard reset after clicking apply. This windows server has two physical network interfaces so I have swapped the cables and network settings on the two interfaces to see if the problem follows the interface. If the public interface goes down again we will know that it is not an issue with the network card. (We also tried another switch we have on hand, no change) Changing network hardware driver versions We've had the same problem with the latest Broadcom driver, as well as the built-in driver that ships in Windows Server 2008 R2. Replacing network cables As a last ditch effort we remembered another change that occurred was the replacement of all of the patch cords between our servers / switch. We had purchased two sets, one green of lengths 1ft - 3ft for the private interfaces and another set of red cables for the public interfaces. We swapped out all of the public interface patch cables with a different brand and ran our servers without issue for a full week ... aaaaaand then the problem recurred. Disable checksum offload, remove TProxy We also tried disabling TCP/IP checksum offload in the driver, no change. We're now pulling out TProxy and moving to a more traditional x-forwarded-for network arrangement without any fancy IP address rewriting. We'll see if that helps. Switch Virtualization providers On the off chance this was related to Hyper-V in some way (we do host Linux VMs on it), we switched to VMWare Server. No change. Switch host model We've reached the end of our troubleshooting rope and are now formally involving Microsoft support. They recommended changing the host model: http://en.wikipedia.org/wiki/Host_model http://technet.microsoft.com/en-us/magazine/2007.09.cableguy.aspx We did that, and.. we'll see.

• Survey for OS/Browsers etc for an external Agency.

  - by ggonsalv

  We need to design an browser application accessed by a fixed set of external entities (providers). I was wondering if there is a pre-existing survey that is 1) Online 2) Determines the browsers being used etc. without the users having to type it in 3) Determine connectivity from IP address. (Like how Speedtest.com does ). It can tell what your ISP is ,etc without having the user fill it in. The ability to add other questions. So basically a recipient of the survey would navigate to the site, the survey questions that can be inferred , are prefilled so as make recipient only answer the non-technical questions of the survey.

• cPanel webmail roundcube direct login

  - by Jinx

  I have a small web hosting that I offer along my web development/design services. I run cent os with cPanel on it and I'd like to have my clients use roundcube by default without ever seeing cpanels page for picking webmail app (squirrel/horde/roundcube). I manage everything on the server so they don't need access to additional features that can be found on that page. So basically, how can I make www.somepage.com/webmail go directly to roundcube for every single account on my server. I know how to do it manually for each account, but that's a pain to do. Thanks!
