  • Using Clojure instead of Python for scalability (multi core) reasons, good idea?

    - by Vandell
    After reading http://clojure.org/rationale and other performance comparisons between Clojure and many languages, I started to think that apart from ease of use, I shouldn't be coding in Python anymore, but in Clojure instead. Actually, I began to fill irresponsisble for not learning clojure seeing it's benefits. Does it make sense? Can't I make really efficient use of all cores using a more imperative language like Python, than a lisp dialect or other functional language? It seems that all the benefits of it come from using immutable data, can't I do just that in Python and have all the benefits? I once started to learn some Common Lisp, read and done almost all exercices from a book I borrowod from my university library (I found it to be pretty good, despite it's low popularity on Amazon). But, after a while, I got myself struggling to much to do some simple things. I think there's somethings that are more imperative in their nature, that makes it difficult to model those thins in a functional way, I guess. The thing is, is Python as powerful as Clojure for building applications that takes advantages of this new multi core future? Note that I don't think that using semaphores, lock mechanisms or other similar concurrency mechanism are good alternatives to Clojure 'automatic' parallelization.

  • Ubuntu 10.04 hung on unattended apt-get upgrade?

    - by hafichuk
    I'm looking into why our ubuntu web server hung this morning and see that there was some package upgrades a few hours prior to the problem. I was able to ssh into the system and get a snapshot from top: top - 08:13:54 up 210 days, 8:25, 2 users, load average: 433.30, 422.40, 375.70 Tasks: 1192 total, 381 running, 810 sleeping, 0 stopped, 1 zombie Cpu(s): 0.5%us, 6.1%sy, 0.0%ni, 93.4%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 49549772k total, 48518392k used, 1031380k free, 960152k buffers Swap: 11595768k total, 279368k used, 11316400k free, 39355664k cached This is a 16 processor system, so I would typically expect a load in the low teens. I tried to restart apache, which didn't work, and subsequently had to do a hard reboot to get it working again (which it is). One thing I found was that the server did an unattended package update. Is it possible that upgrading php or curl (which our web sites use) might have caused apache to stop responding? Here is the snip from the unattended-upgrades.log from this morning: 2012-09-18 06:48:30,076 INFO Initial blacklisted packages: 2012-09-18 06:48:30,076 INFO Starting unattended upgrades script 2012-09-18 06:48:30,077 INFO Allowed origins are: ["['Ubuntu', 'lucid-security']"] 2012-09-18 06:49:37,017 INFO Packages that are upgraded: gnupg-curl php5-dev linux-server dhcp3-common linux-libc-dev php5-curl gpgv gnupg linux-headers-server linux-image-server php5 php5-mysql php-pear php5-cli php5-common libapache2-mod-php5 dhcp3-client 2012-09-18 06:49:37,018 INFO Writing dpkg log to '/var/log/unattended-upgrades/unattended-upgrades-dpkg_2012-09-18_06:49:37.017909.log'

  • How to determine the amount to spend per phrase on Adwords research?

    - by Anonymous -
    My company would like to start a PPC advertising campaign. Whilst I understand the concept and how to set everything up from a technical point of view, this is something I've never done before. Logically, we'd like to test out a wide range of keywords that we think would lead to conversions, which we've put together through brainstorming and with some help from Google's External Keyword Tool. Sub-question whilst I remember - am I correct in thinking that in Google's keyword tool, keywords that we think will perform well that have a low competition yet high monthly searches are good since there will be less advertisers, meaning our bid per click will be less? Is there a common benchmark or process of doing a round of tests with keywords? Should we wait for 100 clicks on each keyword, see which ones have lead to the most sales (or rather, sales that are sustainable with the cost per click of that keyword), then drop the ones which aren't converting and put that budget onto the converting keywords? We realistically have a few hundred keywords/phrases we would like to test, but spending $100 per keyword/phrase is going to work out as quite an expensive test. It would be nice to be able to spend $5-10 per phrase, but I don't think the sample size would be great enough to determine anything usefully reliable. Another approach might be to setup all the keywords, and those that bring the most sales within x hours/days would be the ones we use. What is the common procedure with things like this? I know there are a plethora of companies that specialize in exactly this, but this is something we anticipate doing a lot in the future, so it would make sense to do it in house if at all possible.

  • Poor backlink profile - search rankings not updated for 2+ months

    - by fistameeny
    I am carrying out some work on a website that is a PR2 with a few good quality, relevant backlinks (PR4-6). It has a presence on Twitter that is updated regularly, a Google Places listing, and listings on some decent directories (Qype etc). The site was rebuilt into Drupal 7 two months ago, with all the basics done - URL rewriting, XML Sitemap submitted to Google, and most importantly, good quality, structured content. I've noticed that Google is still showing "old" URL's from the previous version of the site that was ditched 8 weeks ago. I think the site may be penalised under the Penguin update, as a previous SEO company created many low quality links from link farms/directories. My question is what the correct way to deal with this is. Bing Webmaster Tools can "disavow" links, and I guess I can attempt to contact the link farms to have them removed. I've already submitted a request to Google to request that we have the penalty removed as we're trying to tidy up a bad history. We submit updated sitemaps to Google and Bing daily, and have built some further decent quality, relevant links. Is there anything further I can do?

  • Ubuntu does not recognize my built-in monitor.

    - by B3tturTh3nU
    I've recently discovered of a boot problem Ubuntu has with my laptop. I have successfully installed Ubuntu on two other computers, and I've never experienced this problem. What happens is, after the live boot CD loads, the screen goes completely blank. Although, I suspected that there was no problem booting, so I loaded with BIOS only, which worked perfectly fine. Of course, not being very proficient with this, I have no idea what needs to be done to fix the problem. I have switchable graphics cards(the ATI Mobility Radeon HD 5650, and some low-end Intel card), and an Intel i5 quad core processor. I was booting with the Ubuntu 10.10 64 bit desktop distribution. If there's any more information you need from me, please let me know. EDIT: I was able to look into this a bit more, thanks to one of the comments provided, and I have some new information. Ubuntu does seem to be able to recognize both of my graphics cards. The problem I found was that, in the Xorg.0 log, it mentions that there were "no screens found." I'm using a notebook, so the screen is built in. Does anyone know of a way to get Ubuntu to recognize the monitor?

  • Can't connect to Wireless Network - Ubuntu 12.04 LTS & Sabrent A111N USB Dongle

    - by Ohgodwhy
    I've been trying to connect to this network for quite some time. I can't directly connect to the router with a Wire, but can access the Router with other wireless devices without any issues. I had previously tried several other Wifi nic's but none of them would load properly. Today, i went and bought a new (supported) Sabrent A111N USB Dongle, which said explicitly that it works with Linux 2.4 +. I popped the Dongle in, and low-and-behold it immediately said that there were Available Wireless Connections. I selected my connection and tried to connect, but it just loops constantly while saying Wireless Disconnected then attempts to connect again over and over. ifconfig and iwconfig both show my device in a ready and working state. However, iwlist wlan0 scan says that there are no results found. I don't get it... At one point, I could see the CPU in the DHCP client list under the router, but it doesn't fully make the connection (something about a timeout?). Any help would be appreciated.

  • Ubuntu 12.04 Freezes w/ Ethernet Unplugged + Wireless Drops (Acer Aspire 5516)

    - by Grand Master T
    Ubuntu 12.04-12.10 32/64 freezes or won't boot if the Ethernet cable is unplugged and will not hold a wireless connection. Here is my scenario... Laptop: Acer Aspire 5516 Wireless card: Broadcom BCM4312 Ubuntu 12.04 32/64 Issues Unity 3d won't load without the Ethernet cable plugged in. If I let it load with Ethernet plugged in, it will freeze once I disconnect the cable. Unity 2d will load without the Ethernet cable plugged. In Unity 2d, wireless cannot hold a connection. I can connect to a Wireless network, but when I try to use it (i.e. open a browser), it disconnects. I can reconnect by disabling wireless (uncheck Enable Wireless), re-enable wireless, and reconnect. But, it will disconnect again once I start using it. Ubuntu 12.10 Issues Since 12.10 only gives me the option to load 3d (I assume), I experience the same thing as the first issue in 12.04. Attempted Solutions Enable networking/LAN in BIOS Set LAN first in boot priority in BIOS Remove STA wireless driver (bcmwl-kernel-source) and install b43 low power driver (firmware-b43-lpphy-installer). Remove default Network Manager and install Wicd. So far, I have had no luck with fixing this issue. Does anyone have any further suggestions?

  • Any mobile-friendly Credit Card billing solutions for mobile sites similar to Bango?

    - by Programmer
    Are there any mobile-friendly Credit Card billing solutions for mobile sites similar to Bango? The advantages of Bango I have seen compared to regular Credit Card solutions that make it considerably "mobile-friendly" are: 1) It does not require the user to enter their full name and billing address to make a payment. The user is only required to enter their Credit Card number, expiration date, and CVC code (if they are in the U.S., they will also have to enter their Zip Code). That is significantly less input than is normally required for Credit Card payments, which is a big plus on small mobile key pads. After a user makes an initial Credit Card payment, their details are stored by Bango, and the next time the user needs to make a payment with the same Credit Card, they just have to click a single link and it processes the payment on their stored Credit Card. Needless to say, this is very convenient for mobile users as it is analogous to Direct Carrier Billing as far as the user is concerned since they won't need to input any details. The downside with Bango is that their fees are higher than others, all payments must be processed via their site and branding, there is a high minimum ($1.99) and a low maximum ($30) on how much you can charge users, and you need to pay a monthly fee on top of the high transaction costs. It is due to the downsides mentioned above that I am looking for an alternative solution that also does the advantages 1) and 2) above. Is there anything like that? I looked at JunglePay and they do neither 1) nor 2).

  • Will an online degree get you a job that requires "CS or equivalent 4-year degree"? [on hold]

    - by qel
    I'm a nerdy slacker type who didn't get my life together till I was 30. I've had a real job for a couple years doing C#/SQL. I've gotten several raises, but I'm making less than most developers, and the atmosphere is ... not positive. Looking for a new job, I think my applications get thrown out because I don't have a degree. And I want to finish a Bachelor's just to feel like less of a loser. I have a lot of college credits from 1996-2003 and a low GPA, so I don't know if that's worth much. An online degree looks like a good option, but I just don't know what I should be looking at for online schools because they all look like fake degrees. If they had programs equivalent to a real Comp Sci degree, I don't think they would have weird sounding names like they do. University of Phoenix has a B.S./Information Technology-Software Engineering. DeVry has a B.S./Computer Engineering Technology program. But that's not CS, and most other things I see have even more fake-sounding names. Are these useless degrees? Some people say DeVry and UoP are acceptable, some people say they're a joke. I have enough experience now, though, that maybe all I'm missing is being able to check the box that I have a 4-year degree. Harvard Extension seems like a real degree, even if it isn't a real Harvard degree, but I'd have to live there at least 3 months, which kinda defeats the purpose of an online degree fitting around work.

  • 12.10 no audio via hdmi and video speeds up

    - by jackson
    I have a laptop with an ati radeon 4200, on 12.04 everything worked fine, since upgrading to 12.10 I cannot get sound over the hdmi. When I switch to hdmi audio the video speeds up to about 2x. I can use the speakers in my laptop and watch video via hdmi with no problems. Things I have tried: Various tutorials to install the AMD/ATI drivers, all of which resulted in low graphics mode. Checked that everything is properly set in alsamixer, the sound utility and - installed pavucontrol and checked everything in there. Verified the output from cat /proc/asound/cards looks normal When I initially upgraded there was a plethora of problems which I believe were due to the old proprietary driver still being used but not compatible, after a few hours trying to fix that I decided just to back up and do a fresh install which works great except for the above stated problem. Any help would be greatly appreciated!! Finally hopefully this hasn't already been answered, I have tried a few different searches on the boards and haven't come up with anything. $ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: SB [HDA ATI SB], device 0: ALC269VB Analog [ALC269VB Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: HDMI [HDA ATI HDMI], device 3: HDMI 0 [HDMI 0] Subdevices: 0/1 Subdevice #0: subdevice #0

  • My game seems to be incompatible with recording software. What could be causing this?

    - by Lewis Wakeford
    I've just finished a little Game-Dev project for university and I need to record a video to accompany my submission (just in case they can't get my source to work). Basically my game doesn't work at all when FRAPS or Bandicam attempts to attach to it, I get a black screen and a stream of GL INVALID OPERATION messages from my error reporting code. Dxtory can't seem to hook into it correctly at all, it doesn't display it's FPS counter or anything. My game logic appears to be running correctly from the debug traces, it just seems like all the gl library calls break. I don't know a huge amount about how these programs operate so I don't really know what I could be doing to cause this. I've heard they read from the OpenGL frame buffers so maybe I'm doing something wrong there? I'm letting GLFW and GLEW do all the low level initialization, but I have successfully recorded projects with the same setup and recording software. Essentially, has anyone ever run into something like this before or do you know anything about how these programs work that could give a clue as to the cause of the issue?

  • Adding files and folders to a Root Folder (inode/directory)

    - by xBaldwin
    Ok so I'm fairly new to Ubuntu and wasn't even the one who put it one this computer(my friend did while I was storing it at his house because I was in the middle of transitioning between houses), but It's on here so I need to learn what I can so I can use it more effectively. My question at the moment is "Would it be safe to add files/folders to a folder (inode/directory) that requires Root access?" I continue to be informed by the system that the directory I am using is running low on space which I found odd seeing how I should have a lot more room on this computer. That's when I started looking at the directories and found that there are two with a bunch of un-used space on them. One says it has 46.9 GB of free space and the other has 24.9 GB of free space. Seems like a complete waste to not use that space and yet they both say they require Root access to add to them. I know that Root folders and files are normally all system folders and files. I also know that changing or deleting them can mess up the computer which right now I cant afford to do. I just don't know if it would mess anything up to add something to those folders. Thank you in advance to anyone who takes the time to reply and try to teach me about how all that works. I really do appreciate it and will do the same if by some crazy (completely unlikely) reason I have an answer to your question. :-)`

  • Software development company business plan

    - by Navi
    I apologize in advance if this is the wrong forum for this question, so please forward me to the right place. I have about 10 years professional experience as software developer. Mostly on the Java platform doing server side programs. I have picked up a bit of Linux skills on the way as well. I know HTML and Javascript, so I can make a website that would not be too ugly, but I am not going to win any prizes with it. In fact I think I am pretty terrible in the user interface department. My initial plan is to do Android development. I read a few Android books and tried making a few apps. Since it is Java based I think I got the technical side down. Lately I have been thinking about iphone and Mac development, because of the relevant app store/development programs. The trouble is I don't know Objective C. As a side question, how long would it take me to become proficient in Objective C? Considering that I am working on my own and could hire somebody to help me for a short time for low wages if necessary what are my options? What are the pro and cons of the development programs app stores of Android and Apple? Which development/app stores are out there beside the ones I mentioned? Do you think it is necessary to find funds to get me started or should I just use my savings? If you have positive/negative experiences in a similar situations can you please share them? Thanks for your help.

  • Software Manager who makes developers do Project Management

    - by hdman
    I'm a software developer working in an embedded systems company. We have a Project Manager, who takes care of the overall project schedule (including electrical, quality, software and manufacturing) hence his software schedule is very brief. We also have a Software Manager, who's my boss. He makes me write and maintain the software schedule, design documents (high and low level design), SRS, change management, verification plans and reports, release management, reviews, and ofcourse the software. We only have one Test Engineer for the whole software team (10 members), and at any given time, there are a couple of projects going on. I'm spending 80% of my time making these documents. My boss comes from a Process background, and believes what we need is better documentation to improve software: (1) He considers the design to be paramount, coding is "just writing the design down", it shouldn't take too long, and "all the code should be written before the hardware is ready". (2) Doesn't understand the difference between a Central & Distributed Version control, even after we told him its easier to collaborate with a distributed model. (3) Doesn't understand code, and wants to understand every bug and its proposed solution. (4) Believes verification should be done by developer, and validation by the Tester. Thing is though, our verification only checks if implementation is correct (we don't write unit tests, its never considered in the schedule), and validation is black box testing, so the units tests are missing. I'm really confused. (1) Am I responsible for maintaining all these documents? It makes me feel like I'm doing the Software Project Management, in essence. (2) I don't really like creating documents, I want to solve problems and write code. In my experience, creating design documents only helps to an extent, its never the solution to better or faster code. (3) I feel the boss doesn't really care about making better products, but only about being a good manager in the eyes of the management. What can I do?

  • How to uninstall Ubuntu 12.04 LTS dual booting with Windows 7?

    - by user103799
    I need to uninstall Ubuntu 12.04 LTS from my laptop. It's currently dual booting with windows 7. I've searched and found some ways to do this, but all use some kind of a CD to complete the deletion. I have neither the Ubuntu Live CD nor Windows Install CD/Recovery CD. This laptop did not come with one, and I unfortunately have no available storage device to make a recovery CD. Is there a way to completely uninstall Ubuntu 12.04 LTS dual booting without using any hardware? If there's no way, then how to uninstall using the least hardware possible? Or easy to find hardware? I've nothing against Ubuntu. I installed this as a backup/alternative to error-prone Windows 7. However, after a hardware upgrade, including extra RAMs and a new, better CPU, Windows 7 runs smoothly again. Now I'm running low on hard drive space and need the 40 gig or so of space I partitioned for Ubuntu back. Any help is appreciated, and thanks in advance!

  • PHP Image gallery that integrates well into custom CMS

    - by Thorarin
    I've been trying to find an image gallery that plays nice with our custom CMS. I've evaluated a number of them, but none of them seems to have the feature list that I would like: Run on LAMP environment Free software or low license costs (the website belongs to a non-profit organisation) Multi-user support Multiple albums. We're posting concert pictures, and would like an album per event. Pluggable authentication system. I want to reuse the accounts we have for our CMS. Permissions can be done inside the gallery itself, but I want to have a single sign on solution in a maintainable manner, by writing my own plugin/add-on for the software. Upload support (multiple images at the same time) And preferrably also: Can be integrated into a PHP page layout without IFRAMEs Automatic resizing of uploaded images to a maximum size Ability for visitors to place comments This combination is proving hard to find, especially the authentication requirement. I don't want to mess around all over the place in the source code to make it use the existing authentication. A plugin would be ideal, but alternatively a well thought out software design that allows for maintainable surgical changes would be acceptable. Any suggestions on which software I should take a closer look into?

  • How can I configure the embedded wireless card in a Toshiba Satellite Pro 4600 to work under Lubuntu 10.10?

    - by MoLE
    I'm struggling to get the embedded wireless card in this laptop to work. In 7.10 (gutsy) it worked fine. Now I'm trying to get 10.10 (maverick) working on it, and am using the Lubuntu flavour due to the low resources of this laptop. The hardware: Appears to be an embedded pcmcia card. pccardctl ident gives: Socket 0: product info: "TOSHIBA", "Wireless LAN Card", "Version 01.01", "" manfid: 0x0156, 0x0002 function: 6 (network) The default kernel recognises the card and loads the orinoco_cs driver. orinoco_cs 0.0: Hardware identity 0005:0002:0001:0002 orinoco_cs 0.0: Station identity 001f:0001:0006:000e orinoco_cs 0.0: Firmware determined as Lucent/Agere 6.14 Then for some reason, the driver isn't happy with this and gives: orinoco_cs 0.0: Hardware identity 0005:0002:0001:0002 orinoco_cs 0.0: Station identity 001f:0002:0009:0030 orinoco_cs 0.0: Firmware determined as Lucent/Agere 9.48 All seems ok until I try to associate with my access point using Network Manager. eth1: Lucent/Agere firmware doesn't support manual roaming repeated about 10 times then NM gives up. According to the linuxwireless.org wiki page on this driver, this is a known issue, and I quote: Known issues Roaming and WPA_supplicant Lucent/Agere firmware doesn't support manual roaming On the Agere cards, roaming is controlled by the firmware instead of userspace. You will get the above message if userspace attempts to associate with a specific AP rather than by SSID. If you are using wpa_supplicant use ap_scan=2 mode. NetworkManager uses wpa_supplicant, so the above also applies. At this point my google-fu has failed me, and I can't find how to configure network manager to use the mystical "ap_scan=2" mode via wpa_supplicant. I have tried the following suggested solutions (from launchpad or the forums) deleting the agere* files from /lib/firmware using wicd instead of network manager combining both blacklisting the orinoco_cs driver in an attempt to force use of the hostap_cs driver instead (in case it is a prism2 card). Obviously none of them have worked for me. Any hints on how to perform the suggested workaround above? Edit: I have also confirmed working on 8.10 (intrepid) live CD.

  • X won't start, root filesystem mounted read only

    - by TK Kocheran
    I just experienced a very strange and puzzling problem on my machine that I can't seem to get sorted out. I was running Windows on a second partition, and everything was working great. I then went to restart into Linux, and noticed that X wouldn't start. Everything was displayed in super-low resolution, so I tried reinstalling my NVIDIA driver. I started seeing all of these I/O error problems, so I figured that my SSD was bad. After a bit more playing around, I ran fsck on the drive when mounted from a startup disk as well as badsectors and everything looked great. The SMART drive tests all passed and again, everything was looking good, so I rebooted again and still, no joy. I started then getting some weird USB errors, so I followed someone's advice and unplugged my computer's power supply, then started back up again and my graphics looked a lot better in the BIOS and in the boot logo, but X still wouldn't start. I then found out that my main boot drive was being mounted read-only for some reason. What's going wrong? I've done some pretty extensive tests on the SSD from a startup disk such as writing massive files, reading big files, running filesystem checks on the entire disk, and everything is looking great, until I try to boot. Whenever I try installing the drivers with apt-get, I get a ton of ata error messages looking like this: How can I diagnose what's going wrong and fix it so I can get back to work?

  • Model a chain with different elements in Unity 3D

    - by Alex
    I have to model, in unity 3D, a chain that is composed of various elements. some flexible, some rigid. The idea is to realize a human-chain where each person is linked to the other by their hands. I've not tried to implement it yet as i've no idea on what could be a good way to do it. In the game i've to manage a lot of chains of people... maybe also 100 chains composed of 11-15 people. The chain will be pretty simple and there won't be much interaction... Probabily some animation of the people one at time for each chain and some physic reaction (for example pushing a people in a chain should slightle flex the chain) the very problem of this work is that in the chain each object is composed by flexible parts (arms) and rigid parts (the body) and that the connection should remain firm... just like when people handshake... hands are firm and are the wrists to move. i can use C4D to model the meshes. i know this number may cause performance problems, but it's also true i will use low-poly versions of human. (for the real it won't be human, but very simple toonish characters that have harms and legs). So actually i'm trying to find a way to manage this in a way it can work, the performance will be a later problem that i can solve. If there is not a fast 'best-practiced' solution and you have any link/guide/doc that could help me in finding a way to realize this is, it would be very appreciated anyway if you post it. thanks

  • UFW blocking random packets on 443

    - by s2jcpete
    All, I have UFW setup to allow traffic on port 443. It works as expected, though I have a large amount of UFW Block log entries. To Action From -- ------ ---- 80 ALLOW Anywhere 443 ALLOW Anywhere 22222 ALLOW Anywhere 80 ALLOW Anywhere (v6) 443 ALLOW Anywhere (v6) 22222 ALLOW Anywhere (v6) However in my syslog file I see this: [UFW BLOCK] IN=eth0 OUT= MAC=XXX SRC=<foreignip> DST=<serverip> LEN=40 TOS=0x00 PREC=0x00 TTL=116 ID=22025 DF PROTO=TCP SPT=49622 DPT=443 WINDOW=0 RES=0x00 ACK RST URGP=0 About 30 or so seconds later pound (which I'm using for SSL decryption and port redirection) throws a connection timed out messsage. I'm assuming this is because UFW is blocking the packet. I'm at a loss as to an explination. Could the packet be malformed or something, is this normal? Edit - I have since changed the /etc/defaults/ufw and set ipv6=no, so the v6 rules are no longer in the mix. The server is still showing the block / connection timed out behavior though. The new ufw status output is: Status: active Logging: on (low) Default: deny (incoming), allow (outgoing) New profiles: skip To Action From -- ------ ---- 80 ALLOW IN Anywhere 443 ALLOW IN Anywhere 22222 ALLOW IN Anywhere

  • How do I fix broken installation?

    - by Daniel
    Let me start off by saying I'm dual booting 11.04 and Windows 7 on a Thinkpad T61p. The problem may have arisen when I hit the power button during normal startup. I'm fully aware how stupid this is. I don't know why I did it. I did it. Now, I can't get in to Ubuntu. Windows works fine. But when I try to start Ubuntu normally, it seems to run some checks, and does not start up. Sometimes, I see a black screen, and it tells me that it's running certain checks, and then, [ok]. Like... Battery Check Somethingorother [ok] It'll give me 1-5 of these. And then it just does nothing, and I have to turn it off. When I try to start in safe mode... I tried low graphics mode, and after going through a couple of dialogue boxes, I'm brought right back to the safe mode dialogue box. And if I hit 'resume,' a shell pushes up (still that grey on black "your computer is broken" type shell) and asks me to log in. I do, and try to run unity. It tells me something along the lines of: WARNING no DISPLAY variable set and then sets it to " :0" , which doesn't work. And then I can't do anything, really, and I have to restart. (I don't know how to do this from the command line, so I just hard reset. That command would be helpful). Does anybody have any idea how I can get Ubuntu working right again? FTP is less pleasant in Explorer than it is in Nautilus or w/e it is now.
