• Free-flow Alternative to Powerpoint?

  - by Nick Klauer

  So I've been digging around the net trying to find a good set of alternatives to Powerpoint. Part of my interest is that I found one, Prezi, that I liked for it's free-form style. Part of the power of it was that I can zoom out and select any part of the presentation to continue from and it feels much like a mind map or association of thoughts. Are there any other tools that offer anything similar in vein to this way of presenting material? I'm looking for something that just pops differently than a death-by-powerpoint-style presentation, so I would be happy to find tools that help present information in more fluid styles. It doesn't have to mirror Prezi, and I wouldn't want that, but after seeing what Prezi does, I have to think there are other ways of presenting information to a group of people than one square slide at a time.

• where are the "ipmi sel" entries parameter descriptions?

  - by Horatiu

  In order to troubleshoot a possible hardware issue I have installed ipmitools on my server and am doing queries for info related to poweron/poweroffs, hardware added/removed/status. I am trying to find some info on how to interpret sel obtained via ipmi sel list and the output looks like this : 72b4 | 10/31/2013 | 10:42:40 | System Event #0x01 | OEM System boot event | Asserted 72c8 | 10/31/2013 | 10:42:48 | System ACPI Power State #0x82 | S0/G0: working | Asserted I really want to know what "Asserted" means in this context, and also, where can I find a reference with all possible "exit status(es)" ? (Because I think that's what this is, right ?)

• MacBook Pro screen goes dark

  - by Mike M

  I've had my MacBook Pro for two years now; no problems so far (it has had 3rd party RAM from the get go). Today, I'm copying a particularly large VM from an External disk drive to local MacBook disk. It has about 3GB to go and I take off to do some other things and when I come back my screen is "dark". The computer is still on but I can't see anything. I forced a reboot by holding down the power button, it starts up with the "chimes", but still no screen. I've done this several times. Any ideas? Do you think the hard disk activity caused it to get too hot?

• Tracking down random BSOD on windows 7

  - by pehrs

  I have gotten a computer running windows 7 handed to me that randomly, several times a day, bsods with a PAGE_FAULT_IN_NONPAGED_AREA (50) or WHEA_UNCORRECTABLE_ERROR (124). Crashes happens regardless of load. I am running out of ideas for how to track this down. Analyzing the minidumps shows the crash to be in ntkrnlmp.exe/WMIADAP.exe System has plenty of power (600w) Ram checks out fine using memtest86+ over a weekend. System is clean inside. No dust build up. Temperatures stay low. As far as I know (and reliability history shows) no new drivers were installed for several months before the problems started. All drivers are now up to date. sfc /scannow reports the system as clean. CHKDSK reports the disks as clean Removing the AV (Avast) has no effect. Any more things that should be tried on windows 7 before I start replacing the hardware?

• Why doesn't my Droid phone charge when connected to a powered USB hub that is not connected to my computer?

  - by pkaeding

  I notice that my new Motorola Droid phone charges perfectly fine when I connect it to my computer via the USB cable, or if I connect it to a car cigarette lighter-USB adapter, or a wall power-USB adapter. It also works fine when I connect it to a powered USB hub that is connected to my computer. However, if that same powered USB hub is not connected to my computer when I connect the phone, it does not charge. If I connect the computer to the hub, and then connect the phone to the hub, it will charge. If I then disconnect the computer from the hub, the phone will continue to charge. Does anyone know why this is happening, or what I can do to be able to charge my phone from a powered hub, without my computer being present?

• SOLR high CPU usage in amazon EC2

  - by user644745

  I installed solr-3.6 in my local windows box and it worked fine. I installed solr-4.0 in amazon ec2 linux large instance and the cpu usage shot upto 100%. It maintained at 80-90% average cpu power. I thought it could be because of 4.0, So I installed 3.6 in EC2 again. But again the CPU usage was 80-90% average. With both the versions, solr works in EC2. dont know why CPU usage is so high. i started the solr server using "sudo nohup java -jar start.jar &" In my local box java 1.7 is installed and in EC2 it is 1.6.0_24. I have mapped solr dir to an EBS volume. /dev/mapper/vg1-solr 8361916 1935928 6342128 24% /home/ec2-user/SOLR/solr/example/solr Is there any known issue ?

• MacBook says to replace battery. Should I?

  - by Palantir

  Hi! My MacBook says that battery is not charging, and the battery is completely empty (in fact, pressing the button on the battery illuminates no LEDs). If I plug the power adapter off the mac shuts off immediately. I tried with a spare adapter, and it won't charge it. System information says it has 380 cycles. The battery is 2.5 years old. System profiler says the battery has 0 mAh of capacity, and that it should be replaced. Should I just buy a new battery, or should I bring it to an apple point, and leave it there? They can take a look at it (it's on AppleCare), they told me that they will repair it is there is anything wrong with the charging circuit, but they won't give me a new battery. They will keep the laptop for 10 working days at least... I hate when this happens :P

• What does "cpuid level" mean?

  For an example, I put just output from 1 core of a 16 core machine. What does the output mean by "cpuid level" of "6"?

• How to identify cause of system lock on debian squeeze?

  - by David Sanders

  I have a desktop system at work with debian squeeze installed. Every couple days or so, when I come in in the morning, the system appears to be asleep and won't wake up. I suspect it goes into power save mode and then doesn't receive the wake up signal when I click the mouse or touch the keyboard. Does anyone know where I should look in order to start tracking this down? Like log files, etc? I doubt it, but maybe the fact that I'm using a mac aluminum usb keyboard and a wireless usb mouse (that has an off switch) has something to do with it? Maybe, when I turn my mouse off at the end of the day, the system loses track of the device somehow? I dunno :P. Thanks in advance.

• Juniper J4350 out of order

  - by Benjamin Baron

  I have got two (2) Juniper routers J4350 that are out of order : All the interfaces are down (leds on the interfaces don't ligthen, ping dosen't respond) No output on the console port (even when booting) I've tried to reset the router (holding the RESET CONFIG button on the front panel during 15 seconds) and nothing happened, even while booting the device I've opened the router to check the fans. I've removed some dust and nothing has changed. I wanted to precise that the leds on the front panel are all on: The POWER led is green The STATUS led is red The ALARM led is on and is orange The HA (High Availablity) is on and orange as well I have found nothing on the Internet to solve this problem... Thank you for helping me :)

• Repair snapped USB flash drive

  - by Richard Slater

  I have a USB Flash Drive that has had the USB connector snapped away from the circuit board. In the past I have had great sucess with soldering the connector back to the circuit board with 4 solid core wires. Unfortunatly this particular device shows up as "Unknown Device" in device manager and displays 0ma power usage. Giving a closer look at the circuit board it appears that the Data + connector has come away from the PCB. Which would explain why it is not recognised. Is there any practicable way of lifting the data from the device? larger version

• Printer Problems: Snow Leopard with Epson CX 4200 - worked and then didn't?

  - by user33521

  We got a new laptop in the office with Snow Leopard. We installed the new driver for the Epson CX 4200 printer we have and it seemed to be working okay. However, after an Apple update, the printer stopped working. A few days later we saw an update for the Epson driver and so we downloaded and installed that. However, the printer still isn't working. We plugged and unplugged the printer power cable and usb cable, and also tried replacing the ink (because the colour ink light was blinking)...however the printer still isn't working?

• Multiple servers acting like a single one with all the hardware?

  - by marc.riera

  Hello, by now I have 10 servers for hpc, power computing oriented. My users need to launch several processes using qmake. The users are used to work with ubuntu 9.10, and the software from the repositories is switable for them. I've deployed ubuntu 9.10 to all 10 servers (pxe rocks). By now we work with parallel-ssh and cluster-ssh, which allows as to launch the same process to all servers. With this tools this tools the servers remain as independent but with the same software and the same launched command. Now we would like to go to next step and see all the servers as a single one with all the resources from the other 9 as if was its resources. The difference would be substantial in time to process and also time to design the command to launch. Any advice on wich software to use will be very useful? Thanks

• Boot camp with Vista crashes on startup

  - by Mark Pim

  I have a 2006 vintage MacBook Pro (Intel Core 2 Duo) and have been using Boot Camp since it was in beta. I had been running XP SP2 on it with Tiger quite happily. I've recently wiped and reinstalled everything to upgrade to Leopard. After installing Leopard, I fired up the Boot camp assistant and used it to install the Windows 7 RC. That worked really nicely, but my HFS+ driver didn't work under Windows 7 yet so I decided to install Vista instead. I didn't repartition the drive, just launched the Vista installation disk from BIOS and told it to overwrite the existing Windows 7 install. It installed fine and I installed the Boot Camp drivers, still all fine. Now, however, every time I boot into Windows and login it hard reboots itself as the desktop is appearing. After this it works fine again. Until the next power off. Has anyone had any similar problems? Or can offer suggestions on how to solve this?

• How to use my computer to control a lamp?

  - by nona urbiz

  I've been researching computer automation systems, but everything I've found has been overkill for what I'm interested in. Can anyone help me control a lamp that is on my desk, plugged in the wall beneath the desk, with my computer (also on the desk, usually). What got me thinking is that I have the lamp plugged into a Belkin extension cord/surge protector that came with a wireless switch that toggles the power going to 6 of the eight sockets. Can I somehow hook my computer into this? I'm not too afraid to get into some wiring type thing, but do have a somewhat limited budget. It'd also be cool to get a dimmer in the loop too. thanks aha. after more research, i have realized what i'm looking for is instructions for a DIY version of this that won't look so ugly, and that i can build a UI for rather than shortcuts.

• Laptop VGA Output Stopped Working

  - by Jack7890

  I regularly use an external monitor with my laptop. Today, when I booted up, the external monitor refused to work--it just keeps going into power save mode. I tried a different external monitor and had the same problem, so it must be a problem with the laptop itself. Things I've tried: Going into the Display Settings via the Control Panel (I'm running Vista) and attaching/unattaching/reattaching the external monitor. Turning the computer off, unplugging, plugging it back in, and rebooting Blowing into the VGA out to get rid of any dust Toggling through the Fn+F7 options I'm thinking maybe this is an issue with my video card? If necessary, I'm comfortable opening up my laptop and playing around with things, but I'm not sure what to look for. Does anyone have any suggestions?

• How to change or remove all traces of original author name in Excel 2010 document

  - by Adam Ryczkowski

  At our company we need to deploy one Excel Workbook in that way that nobody would see it is made by us by looking at the Office metadata. What fields do we need to look for? I know, that the document has track of original writer and the last save author. But is it all? I guess there might be some hidden properties, that might give our company name. Where to look for such fields? Is there any good editor available, or will explorer's property page give enough power? I use Excel 2010

• Laptop turns off after 20 minutes of use

  - by Christoph

  My laptop a sony vaio VGN-NW11S http://www.trustedreviews.com/Sony-VAIO-VGN-NW11S-S---15-5in-Laptop_Laptop_review. Everytime i turn it on, in safe mode or not, if i try to open an application i.e. run a process such as google chrome or event viewer, defrag, virus scan, it completely turns off without warning, nor giving a trace of events the next time I switch it on. Apart from that, I had worries it might be my battery or power supply but I dont think it is that, I took the laptop apart cleaning fans etc. and have ordered some cpu paste as I checked to see the condition of the processor. I will post to see if re-applying the paste works. One more thing, when the heavy processes kick in, the fan starts to make a lot of noise, maybe trying to cool down the CPU? Any ideas on what else it could be and what I could do to test what is wrong?

• Strange noise from my laptop when it is closed

  - by gotqn

  I am fan of powerfull PCs with huge wide screen monitors but I have bought an laptop as gift to my parents. This is the description: "second-handed" lenovo (and there is a sign "ThinkPad" Intel Core Duo CPU T6570 2.10 GHz 64 bits Windows 7 Ultimate and the issue is that when the laptop is turn on and then closed, after a interval of time (I am not sure how much exactly but I believe it is several hours) a strange noise come from the laptop. The noise is something like a "start-up" noise of old computers. I first thought this is some hardware issue but everything seems to work fine. Has anyone an idea what can cause this type of noise or a what can I do in order to track the problem down? I am not sure if this is a important thing, but the laptop is always connected to the power. Note: I have just noticed that the sound is generated again when the laptop is closed and then opened. Note: This is link to the audio - http://yourlisten.com/channel/content/16934332/WindowsStrangeNoise

• Can't boot into Linux partition after installation

  - by Otto

  I just installed Ubuntu. I created a partition in MacOSx using Disk utility, then deleted the partition and installed Ubuntu on the free space created. After the installation, Ubuntu said it would reboot. I hang on shutdown (which is normal, as google told me), so I used the power button to turn the MacBook off. Now I want to boot into Ubuntu. Pressing option/alt on startup only shows me the MacOSx and Windows partition. Also, the Linux partition isn't showing up on my MacOSx desktop. And in Disk Utility, I can see 3 grayed out partitions: "disk0s4", "disk0s5" and "Linux Swap". What can I do to boot into Ubuntu without losing my other partitions? Thank you for your help.

• Computer froze up

  - by Arlen Beiler

  Why would my computer freeze up out of the blue? I have Apache Webserver w/php, and MySQL server installed. I am not sure exactly when it happened, but I was doing something on a wordpress site that I have installed, and it just waited and waited and waited. Then, all the folders on it that were open on my other computer closed, as though I had disconnected it. Then the skype account went offline. The computer was totally froze. I thought maybe it was someone on logmein, but disconnecting it from the network didn't do anything. I had to "crash" it (held in the power button till it shutdown). It started up normally then and the logs showed absolutely nothing wrong. And doing the same thing that I did when it froze didn't repeat the freeze. Any ideas, I never had this happen before.

• iPhone always assigned wrong ip

  - by Ashley Ray

  for some reason most of the time my iPhone connects to the home network the ip address seems wrongly assigned as it 'loses connection' even even with strong reception. If I change the ip address to a static from 168.2.10 to 168.2.15 works fine until it appears to renew back to the prior. I am using a power-plug extender from the modem to router. Then have a laptop Printer playstation tv and another iPhone that always connect fine. The modem also has a crappy wireless which I haven't connected any devices to. I'm sure the forum will have a simple answer!

• How can I launch RemoteApp on Windows Server from server itself at startup

  - by Rusted

  I have Windows Server 2008 R2 with RDS and custom desktop (GUI) application installed on the server. The app is started as RemoteApp on server by user from his desktop computer (or, sometimes, he can work from notebook over VPN). Some details about environment: the server automatically shuts down every evening and automatically power-on every morning (this is a requirement) desktop application do some precalculations/precaching on startup and it can take lot of time mentioned application have some memory leaks, so I can't use hibernate instead of shutdown When user launching this app from his computer, he can't start work with it until this app finishes pre-initialization. Is there any way to start RemoteApp session at the server startup (without actual user logon), so that the user could connect to this session from his computer later? I don't want to involve the user's computer to make it work. I have tried to do it by Windows startup script, but have no luck - starting RDP session requires actual user session.
