• Is .Net Going to Die As far as Server Apps and Desktop Apps are concerned? [closed]

  - by Graviton

  Possible Duplicate: What does Windows 8 mean for the future of .NET? The Windows 8 preview doesn't mention .Net, and the demo seems to showcase what HTML, CSS and Javascript can do on Windows 8 OS. The impression I get from watching it is that HTML , Javascript is going to figure prominently in Windows 8, even for the traditional windows desktop applications. That, couple with the fact that there is no mentioning of .Net 5 and Visual Studio 2012 or 2013( MS is pretty quick to announce the next generation VS tools) yet, makes me worry that sooner or later, Microsoft will abandon the .Net platform completely. Yes, not just abandoning Silverlight, but the .Net platform in general. Which means that all the desktop apps, server apps you wrote in .Net is going to be obsolete, much like how VB6 apps are now obsolete. Is .Net going to die? Of course you won't find that all .Net apps stop running tomorrow. But will there be a day-- even when at that time Microsoft is alive and kicking-- when .Net apps are looked upon as legacy apps in the way we perceive VB6 apps? Edit: I've changed the wording of the title, so it's not a dupe of existing question. Please take note.

• Grading an algorithm: Readability vs. Compactness

  - by amiregelz

  Consider the following question in a test \ interview: Implement the strcpy() function in C: void strcpy(char *destination, char *source); The strcpy function copies the C string pointed by source into the array pointed by destination, including the terminating null character. Assume that the size of the array pointed by destination is long enough to contain the same C string as source, and does not overlap in memory with source. Say you were the tester, how would you grade the following answers to this question? 1) void strcpy(char *destination, char *source) { while (*source != '\0') { *destination = *source; source++; destionation++; } *destionation = *source; } 2) void strcpy(char *destination, char *source) { while (*(destination++) = *(source++)) ; } The first implementation is straightforward - it is readable and programmer-friendly. The second implementation is shorter (one line of code) but less programmer-friendly; it's not so easy to understand the way this code is working, and if you're not familiar with the priorities in this code then it's a problem. I'm wondering if the first answer would show more complexity and more advanced thinking, in the tester's eyes, even though both algorithms behave the same, and although code readability is considered to be more important than code compactness. It seems to me that since making an algorithm this compact is more difficult to implement, it will show a higher level of thinking as an answer in a test. However, it is also possible that a tester would consider the first answer not good because it's not readable. I would also like to mention that this is not specific to this example, but general for code readability vs. compactness when implementing an algorithm, specifically in tests \ interviews.

• How can I save state from script in a multithreaded engine?

  - by Peter Ren

  We are building a multithreaded game engine and we've encountered some problems as described below. The engine have 3 threads in total: script, render, and audio. Each frame, we update these 3 threads simultaneously. As these threads updating themselves, they produce some tasks and put them into a public storage area. As all the threads finish their update, each thread go and copy the tasks for themselves one by one. After all the threads finish their task copying, we make the threads process those tasks and update these threads simultaneously as described before. So this is the general idea of the task schedule part of our engine. Ok, well, all the task schedule part work well, but here's the problem: For the simplest, I'll take Camera as an example: local oldPos = camera:getPosition() -- ( 0, 0, 0 ) camera:setPosition( 1, 1, 1 ) -- Won't work now, cuz the render thread will process the task at the beginning of the next frame local newPos = camera:getPosition() -- Still ( 0, 0, 0 ) So that's the problem: If you intend to change a property of an object in another thread, you have to wait until that thread process this property-changing message. As a result, what you get from the object is still the information in the last frame. So, is there a way to solve this problem? Or are we build the task schedule part in a wrong way? Thanks for your answers :)

• Chrome window controls in xubuntu 12.04

  - by Norbert

  I'm a long time ubuntu 10.04 LTS user, very used to having window controls on top left borders. New computer with new video card requires newer kernel. Unity doesn't suit and much googling turned up recommendations for xubuntu. Installed 12.04 and first aggravation is window controls at upper right a la Windows. No problem ... Settings Manager - Windows Manager - rearrange button layout Fixes everything until ... I abandoned firefox long ago because of memory leak issues and general fat. I fetch a current version of chrome (19.0.1084.52) and install. Once adblock is added and it's the default browser, everything's great. Except ... Alone among all applications, chrome will not honour the window manager's preferred button layout. Buttons are at upper right no matter what I try. Uninstall and then reinstall: nope. Trawl through /home/user/.config/google-chrome/* looking for a likely setting: nope. Search the web: nothing useful. How do I get chrome's window decoration in sync? Thanks very much for any and all help.

• Bomberman clone, how to do bombs?

  - by hustlerinc

  I'm playing around with a bomberman clone to learn game-developement. So far I've done tiles, movement, collision detection, and item pickup. I also have pseudo bombplacing (just graphics and collision, no real functionality). I've made a jsFiddle of the game with the functionality I currently have. The code in the fiddle is very ugly though. Scroll past the map and you find how I place bombs. Anyway, what I would like to do is an object, that has the general information about bombs like: function Bomb(){ this.radius = player.bombRadius; this.placeBomb = function (){ if(player.bombs != 0){ // place bomb } } this.explosion = function (){ // Explosion } } I don't really know how to fit it into the code though. Everytime I place a bomb, do I do var bomb = new Bomb(); or do i need to constantly have that in the script to be able to access it. How does the bomb do damage? Is it as simple as doing X,Y in all directions until radius runs out or object stops it? Can I use something like setTimeout(bomb.explosion, 3000) as timer? Any help is appreciated, be it a simple explanation of the theory or code examples based on the fiddle. When I tried the object way it breaks the code.

• https:// search results appearing on Google for purely http:// site

  - by hydrurga

  I started weeding through my site's search results from Google today, using a site: search, to determine if there are any links that cause 404s and thus need redirecting. To my amazement I noticed numerous https:// results relating to various pages. My site doesn't have a SSL certificate, doesn't serve such pages, doesn't internally link to https:// pages, doesn't include any such files in its sitemap.xml and, for all of these, never has. I decided to do a Google search for https://<my site> and found one site that incorrectly refers to the root of my site with a https:// prefix - I will try to contact them to get them to correct this. I'm not sure however how Googlebot managed to index the non-root files as https://. I can't find any external links to them and surely, without certification, Googlebot should have stalled at the first request? I've just added the following lines to the site's .htaccess (although the surfer still has to navigate through the browser's "This site is a security risk. Abandon hope all ye who enter here!" message(s) first to get there): RewriteEngine On RewriteCond %{HTTPS} on RewriteRule ^(.*)$ http://www.<my site>.org/$1 [R=301,L] replacing <my site> with my domain name. My big question is this though - I would like to use the Google Webmaster Tools Remove URLs feature to remove the https:// pages from the index. Can I be guaranteed that this will only remove the https:// versions of each relevant page and not the valid http:// versions? My thanks to anyone who can help me out with this particular question and the issue in general.

• Script language native extensions - avoiding name collisions and cluttering others' namespace

  - by H2CO3

  I have developed a small scripting language and I've just started writing the very first native library bindings. This is practically the first time I'm writing a native extension to a script language, so I've run into a conceptual issue. I'd like to write glue code for popular libraries so that they can be used from this language, and because of the design of the engine I've written, this is achieved using an array of C structs describing the function name visible by the virtual machine, along with a function pointer. Thus, a native binding is really just a global array variable, and now I must obviously give it a (preferably good) name. In C, it's idiomatic to put one's own functions in a "namespace" by prepending a custom prefix to function names, as in myscript_parse_source() or myscript_run_bytecode(). The custom name shall ideally describe the name of the library which it is part of. Here arises the confusion. Let's say I'm writing a binding for libcURL. In this case, it seems reasonable to call my extension library curl_myscript_binding, like this: MYSCRIPT_API const MyScriptExtFunc curl_myscript_lib[10]; But now this collides with the curl namespace. (I have even thought about calling it curlmyscript_lib but unfortunately, libcURL does not exclusively use the curl_ prefix -- the public APIs contain macros like CURLCODE_* and CURLOPT_*, so I assume this would clutter the namespace as well.) Another option would be to declare it as myscript_curl_lib, but that's good only as long as I'm the only one who writes bindings (since I know what I am doing with my namespace). As soon as other contributors start to add their own native bindings, they now clutter the myscript namespace. (I've done some research, and it seems that for example the Perl cURL binding follows this pattern. Not sure what I should think about that...) So how do you suggest I name my variables? Are there any general guidelines that should be followed?

• How to integrate technical line/functional manager into Scrum team?

  - by thegreendroid

  We have recently had a new line manager start who is managing our Scrum team. He is immensely experienced in our field but is relatively inexperienced at Agile/Scrum. He has extensive technical expertise in embedded software (the team's domain) that would go to waste if not utilised properly. However, the team is wary of making a line manager part of the Scrum team. The general consensus is that the line manager should not be part of the Scrum team at all. There are a number of issues that may crop up, e.g. the team may start "reporting" to the manager (i.e. a daily status update!), the manager may start to micro-manage team members etc etc. As it currently stands, he has already said that he feels like an outsider within the team. We really want to make use of his technical skills, we'd be foolish if we didn't because we are a relatively inexperienced and young team of twenty somethings. What would be the best approach to integrate a senior "technical" line manager in a Scrum team and make him feel like he is part of the team?

• Introducing a (new) test method to a team

  - by Jon List

  A couple of months ago i was hired in a new job. (I'm fresh out of my Masters in software engineering) The company mainly consists of ERP consultants, but I was hired in their fairly small web department (6 developers), our main task is ERP/ecom integration (ERP-integrated web shops). The department is growing, and recently my manager asked me to start thinking about introducing tests to the team, i love a challenge, but frankly I'm a bit scared (I'm the least experience member of the team). Currently the method of testing is clicking around in the web shop and asking the customer if the products are there, if they look okay, and if orders are posted correctly to the ERP. We are getting a lot of support cases on previous projects, where a customer or a customer's customer have run into errors, which - i suppose - is why my manager wants more structured testing. Off the top of my head, I though of some (obvious?) improvements, like looking at the requirement specification, having an issue tracker, enabling team members to register their time on a "tests"-line on the budget, and to circulate tasks amongst members of the team. But as i see it we have three main challenges: general website testing. (javascript, C#, ASP.NET and CMS integration tests) (live) ERP integration testing (customers rarely want to pay for test environments). adopting a method in the team I like the responsibility, but I am afraid that I'm in a little bit over my head. I expect that my manager expects me to set up some kind of workshop for the team where I present some techniques and ideas and where we(the team) can find some solutions together. What I learned in school was mostly unit testing and program verification, not so much testing across multiple systems and applications. What I'm looking for here, is references/advice/pointers/anecdotes; anything that might help me to get smarter and to improve the current method of my team. Thanks!! (TL;DR: read the bold parts)

• Benefits of Masters of Engineering Professional Practice for the lowly (yet aspiring) programmer

  - by Peter Turner

  I've been looking into in state online degree programs 'to fit my busy lifestyle' (i.e. three children, wife and hour and a half commute). One interesting one I've found is that Master of Engineering in Professional Practice. It looks more useful and practical than a MBA in project management. I'll contact the admission dept there about the specifics. But here I'm just asking in general. Do the courses in this degree apply to software engineering/development in even an abstract sense. The university I'm looking at does not have a Software Engineering major in the school of engineering. I'm not interested in architecture astronomy, but I am interested in helping my company succeed and being able to communicate technical information at a high and effective level as well as being able to lead my co-programmers toward a more robust end product. So my multipart question is: What might be the real benefit to me and my brain and How do I convince my boss (the owner of the company, who does do some tuition reimbursement) that just because it doesn't say anything about software that it might still do us some good? Oh, and how do I get past the fact that a masters degree would make me more qualified to be the project manager than... the project manager? (who is my supervisor)

• Is there an application that converts a PC into a video game kiosk/arcade machine?

  - by Rahil627

  Sorry to make the question so vague. What I ultimately want is software that allows people to play independent video games on a PC and not have to worry about maintaining it. Imagine a game that was made in a few hours that does not have a restart button and crashes often. It should be able to handle these kinds of things and do more! The software should: allow the game to be restarted manually handle game crashes (likely by restarting the game) restrict the user from doing anything crazy later... offer a UI to select the game from a list handle pre-configured key bindings cross-platform (start with windows) I just want to know if this exists already before I start creating one. As of now AutoHotKey is being used to do this sloppily. If such software does not exist then perhaps someone could recommend a general open source Kiosk software? Open Kiosk? I'll take anything. (I also could not find a related tag. Not even sure if this question should be here rather than stackoverflow)

• School vs Self-Taught [duplicate]

  - by Joan Venge

  This question already has an answer here: Do I need a degree in Computer Science to get a junior Programming job? [closed] 8 answers Do you think university is a good learning environment or is it better to be autodidact? [closed] 3 answers Do you think formal education is necessary to gain strong programming skills? There are a lot of jobs that aren't programming but involves programming, such as tech artists in games, fx tds in film for example. I see similar patterns in the people I work where the best ones I have seen were self-taught, because of being artists primarily. But I also see that while the software, programming knowledge is varied and deep, hardware knowledge is very basic, including me, again due to lack of formal education. But I also work with a lot of programmers who possess both skills in general (software and hardware). Do you think it's necessary to have a formal education to have great programming skills? Would you think less of someone if he didn't have a degree in computer science, or software engineering, etc in terms of job opportunities? Would you trust him to do a software engineering job, i.e. writing a complex tool? Basically I feel the self-taught programmer doesn't know a lot of things, i.e. not knowing a particular pattern or a particular language, etc. But I find that the ability to think outside the box much more powerful. As "pure" programmers what's your take on it?

• Dealing with 2D pixel shaders and SpriteBatches in XNA 4.0 component-object game engine?

  - by DaveStance

  I've got a bit of experience with shaders in general, having implemented a couple, very simple, 3D fragment and vertex shaders in OpenGL/WebGL in the past. Currently, I'm working on a 2D game engine in XNA 4.0 and I'm struggling with the process of integrating per-object and full-scene shaders in my current architecture. I'm using a component-entity design, wherein my "Entities" are merely collections of components that are acted upon by discreet system managers (SpatialProvider, SceneProvider, etc). In the context of this question, my draw call looks something like this: SceneProvider::Draw(GameTime) calls... ComponentManager::Draw(GameTime, SpriteBatch) which calls (on each drawable component) DrawnComponent::Draw(GameTime, SpriteBatch) The SpriteBatch is set up, with the default SpriteBatch shader, in the SceneProvider class just before it tells the ComponentManager to start rendering the scene. From my understanding, if a component needs to use a special shader to draw itself, it must do the following when it's Draw(GameTime, SpriteBatch) method is invoked: public void Draw(GameTime gameTime, SpriteBatch spriteBatch) { spriteBatch.End(); spriteBatch.Begin(SpriteSortMode.Immediate, BlendState.AlphaBlend, null, null, null, EffectShader, ViewMatrix); // Draw things here that are shaded by the "EffectShader." spriteBatch.End(); spriteBatch.Begin(/* same settings that were set by SceneProvider to ensure the rest of the scene is rendered normally */); } My question is, having been told that numerous calls to SpriteBatch.Begin() and SpriteBatch.End() within a single frame was terrible for performance, is there a better way to do this? Is there a way to instruct the currently running SpriteBatch to simply change the Effect shader it is using for this particular draw call and then switch it back before the function ends?

• Was API hooking done as needed for Stuxnet to work? I don't think so

  - by The Kaykay

  Caveat: I am a political science student and I have tried my level best to understand the technicalities; if I still sound naive please overlook that. In the Symantec report on Stuxnet, the authors say that once the worm infects the 32-bit Windows computer which has a WINCC setup on it, Stuxnet does many things and that it specifically hooks the function CreateFileA(). This function is the route which the worm uses to actually infect the .s7p project files that are used to program the PLCs. ie when the PLC programmer opens a file with .s7p the control transfers to the hooked function CreateFileA_hook() instead of CreateFileA(). Once Stuxnet gains the control it covertly inserts code blocks into the PLC without the programmers knowledge and hides it from his view. However, it should be noted that there is also one more function called CreateFileW() which does the same task as CreateFileA() but both work on different character sets. CreateFileA works with ASCII character set and CreateFileW works with wide characters or Unicode character set. Farsi (the language of the Iranians) is a language that needs unicode character set and not ASCII Characters. I'm assuming that the developers of any famous commercial software (for ex. WinCC) that will be sold in many countries will take 'Localization' and/or 'Internationalization' into consideration while it is being developed in order to make the product fail-safe ie. the software developers would use UNICODE while compiling their code and not just 'ASCII'. Thus, I think that CreateFileW() would have been invoked on a WINCC system in Iran instead of CreateFileA(). Do you agree? My question is: If Stuxnet has hooked only the function CreateFileA() then based on the above assumption there is a significant chance that it did not work at all? I think my doubt will get clarified if: my assumption is proved wrong, or the Symantec report is proved incorrect. Please help me clarify this doubt. Note: I had posted this question on the general stackexchange website and did not get appropriate responses that I was looking for so I'm posting it here.

  Oracle Enterprise Manager continues to expand its Eco-system with the NEW Extensibility Exchange! The Exchange offers a searchable listing of Enterprise Manager entities. Today it’s stocked with plug-ins and connectors for Enterprise Manager 12c and 11g. Anyone - partners, customers, ACE community members, anyone - can post an entity subject to approval of course. So in addition to plug-ins and connectors, the Exchange will have best practices, deployment procedures, templates, and essentially any Enterprise Manager entity that’s relevant. The Exchange provides Development Resources to guide contributors in the creation of plug-ins and connectors. A Community Resources page features plug-ins validated through the Oracle Validate Integration program as well as some other contributions important to customers.  You can also discover ways to get more involved with Enterprise Manager through the user and partner communities. The Exchange was announced in the October 2nd Enterprise Manager Partner Press Release  and is being presented at Oracle OpenWorld 2012 during the following sessions:    •    “Using Oracle Enterprise Manager to Manage Your Own Private Cloud” General Session – Tuesday Oct 2nd    •    “Managing Heterogeneous Environments with Oracle Enterprise Manager” Conference Session – Tuesday Oct 2nd    •    “Using Management Already Built into Oracle Products: Oracle Enterprise Manager” Oracle Partner Network Exchange Session – Wednesday Oct 3rd Check it out at http://www.oracle.com/goto/emextensibility, and let us know what you think by posting a comment below or clicking the "Forum" button at the Exchange itself.

• Clustering and custom applications

  - by Ahmed ilyas

  I was not entirely sure what tags to put but hope this is ok. This is just a general question in regards to clustering and applications: so lets say we have a clustered environment setup. We cluster SQL Server (I dont know exactly how its done but lets just say its been done for the sake of argument). Now if a website or application is trying to access that database for read/write (say an ASP.NET app or a C# Winforms app) and during that time SQL goes down - it takes a couple of minutes for the clustering failover to take affect to switch to another node. What happens during this time? I think it will time out/unable to connect. BUT is there a way for it to place the request in some pipeline so when the cluster node is back up/switched over it will continue as normal? as you can see, I know nothing much about clustering! what about your own custom .NET apps? Would there be a special way to develop them? I know that you can say create a simple Hello world app, and cluster that but they wouldnt be something you could see interms of the UI or anything, so they would effectively need to be developed as a Windows Service perhaps or even as a standard Console app which runs and not wait for user input but you wouldnt see any output from it (unless you redirect output to somewhere else) What im getting at here is... for those who have experience or developed a cluster application in .NET, how did you do it and what are the things to be aware of? For example we have the cloud service - fundamentally its built on clustering - if there is an outage, another node takes place and service is resumed as normal but we dont really see much of that downtime.

• What exactly do I have to pay attention for when choosing Windows Hosting Provider?

  - by user850010

  This is my first time choosing a hosting company. It is for a web site made in asp.net mvc3. So I was thinking choosing a provider would be easy since I found this page http://www.microsoft.com/web/Hosting/Home which contains hosting offers. Now hours later, I am still searching. The reason is that as soon as I start investigating about particular company, something stands out that I do not like. Here are some examples what I noticed when checking various companies in more detail: Company "about us" page is lacking in information about their company. Few of them had just general description what they do and nothing else, while some others had information like company name but had no address. Checking company name in Business Registry Searches gave no results. Two of the companies I checked had both company name and address but I was unable to find them in the registry. Putting company domain into Google gave mostly results from that domain or web hosting review sites but not much else. I am assuming that good companies should have search results from other sites too. Low Alexa Traffic Rank. There was one company which had a site that looked very professional but their alexa traffic ranking was like 2 million. Are there any other factors I should pay attention to when choosing a hosting company? Do I have legitimate concerns or am I just too paranoid?

• Precautions during SSH

  - by Shagun

  I recently had to give away my Ubuntu 12.10 root password to one of my friends so that he could SSH into my system and send some files to me. Now he is my friend and I trust him so I was not reluctant in sharing my password. And I did change it afterwards. But it just struck me how can I view all the commands that were executed by some other user remote logging into my system (obviously not my friend. I mean in general).To what extent can they access my data (especially my passwords eg I use Last Pass so can they access my account passwords as well??) And if they open any browser after logging into my system do they have access to all my passwords provided I have saved them using the "remember password" option given by chrome Also what precautions I should take when I am allowing some one to remote login in my system and how can I track the various commands used by them or the changes they made in my system. Also is there some simple way to get notified whenever some one logs into my system apart from checking the /var/log/auth.log file??

• Regulating how much to draw based on how much was drawn last frame.

  - by Mike Howard

  I have a 3D game world on an iPhone (limited graphics speed), and I'm already regulating whether I draw each shape on the screen based on it's size and distance from the camera. Something like... if (how_big_it_looks_from_the_camera > constant) then draw What I want to do now is also take into account how many shapes are being drawn, so that in busier areas of the game world I can draw less than I otherwise would. I tried to do this by dividing how_big_it_looks by the number of shapes that were drawn last frame (well, the square root of this but I'm simplifying - the problem is the same). if (how_big_it_looks / shapes_drawn > constant2) then draw But the check happens at the level of objects which represent many drawn shapes, and if an object containing many shapes is switched on, it increases shapes_drawn lots and switches itself back off the next frame. It flickers on and off. I tried keeping a kind of weighted average of previous values, by each frame doing something like shapes_drawn_recently = 0.9 * shapes_drawn_recently + 0.1 * shapes_just_drawn, but of course it only slows the flickering down because of the nature of the feedback loop. Is there a good way of solving this? My project is in Objective-C, but a general algorithm or pseudo-code is good too. Thanks.

• Can I remove the systems from a component entity system?

  - by nathan

  After reading a lot about entity/component based engines. I feel like there is no real definition for this kind of engine. Reading this thread: Implementing features in an Entity System and the linked article made me think a lot. I did not feel that comfortable using System concept so I'll write something else, inspired by this pattern. I'd like to know if you think it's a good way to organize game code and what improvements can be made. Regarding a more strict implementation of entity/component based engine, is my solution viable? Do I risk getting stuck at any point due to the lack of flexibility of this implementation (or anything else)? My engine, as for entity/component patterns has entities and components, no systems since the game logic is handled by components. Also, I think the main difference is the fact that my engine will use inherence and OOP concepts in general, I mean, I don't try to minimize them. Entity: an entity is an abstract class. It holds his position, width and height, scale and a list of linked components. The current implementation can be found here (java). Every frame, the entity will be updated (i.e all the components linked to this entity will be updated), and rendered, if a render component is specified. Component: like for entity, a component is an abstract class that must be extended to create new components. The behavior of an entity is created through his components collection. The component implementation can be found here. Components are updated when the owning entity is updated or for only one specific component (render component), rendered. Here is an example of a logic component (i.e not a renderable component, a component that's updated each frame) in charge of listening for keyboard events and a render component in charge of display a plain sprite (i.e not animated).

• Why nautilus quicklist is not working?

  None of my bookmarks (Documents, Pictures, Download, Dropbox, Ubuntu One, Music, Public) are correctly shown but they won't open if I right click on the Home icon and select them.

I've read similar questions (http://askubuntu.com/questions/184504/unity-home-quicklist-not-working-when-nautilus-is-closed and unity home quicklist not working) but my problem seems different...

• How do I re-enable the backlight?

  - by Scott Severance

  Since Oneiric, if I leave my machine (HP Mini 110 netbook) unattended and it goes into power-save mode, the backlight gets disabled. How can I turn it back on? Note that the keyboard backlight controls (Fn+F4 and Fn+F3) don't have any effect in this situation. I've already filed a bug, but filing a bug doesn't fix my problem. I tried this workaround posted in this bug report dealing with Acer laptops: sudo setpci -s 00:02.0 F4.B=0 However, if anything, that command makes things worse. In the general case, I can see a little bit if I'm in a dark room with a flashlight aimed just so. But after running setpci I can't see anything. And I find the setpci documentation to be utterly incomprehensible, so I don't know whether I need to tweak my command somehow or whether I'm completely barking up the wrong tree. Update: I've found a workaround: I'm now booting with the kernel parameter acpi=off. This disables power management, which prevents the machine from going into power saving mode and thus failing to come back up correctly. Of course, not having power management means that I can't use suspend or do anything to manage power other than powering it off (even then, I have to manually use the power switch). Also, it prevents me from using Unity 3D or Gnome Shell, forcing me into Unity 2C or Gnome Classic. So, I'd really like to be able to stop using this hack.
