• Why is my new PC so slow at startup?

  - by rumtscho

  Bought a new PC this weekend, and it works really good. Only I have one big problem: startup time. Its BIOS needs 62 sec to load, then from Grub start to pw entering screen it's another 26 sec. I think this is a lot, because my old PC needs 34 sec for BIOS and another 8 sec to pw screen. After I enter the pw, the desktop is usable with practically no delay on both. The new PC is a core i7-930, running a Lucid Lynx 64 bit from a Intel Postville SSD (no internal HDs). The old PC is a Pentium 4 celeron (forgot the clock speed) running a Lucid Lynx 32 bit from an ATA 100 hard drive. Neither PC is overclocked. The new one has boot sequence 1.DVD ROM, 2.SSD (connected over SATA in AHCI mode), 3. removable drive. The old one boots from 1. DVD ROM, 2. HDD, 3. Floppy. Neither has a second OS installed. The new one has less software installed than the old one (I think), but the boot time difference was noticeable even before I made any installs. As far as I know, just the SSD should be enough to make a noticeable difference in boot time. I thought that having a good mainboard on the new PC as opposed to the basic office model on the old one would also mean a faster loading BIOS. If these assumptions are right, I guess I must have misconfigured something in the BIOS of the new PC. How should I configure it for a fast boot? It has an ASUS P6X58D board with an AMI BIOS, if you need the BIOS revision number I could post that too.

• Nearest color algorithm using Hex Triplet

  - by Lijo

  Following page list colors with names http://en.wikipedia.org/wiki/List_of_colors. For example #5D8AA8 Hex Triplet is "Air Force Blue". This information will be stored in a databse table (tbl_Color (HexTriplet,ColorName)) in my system Suppose I created a color with #5D8AA7 Hex Triplet. I need to get the nearest color available in the tbl_Color table. The expected anaser is "#5D8AA8 - Air Force Blue". This is because #5D8AA8 is the nearest color for #5D8AA7. Do we have any algorithm for finding the nearest color? How to write it using C# / Java?

• Apache /server-status/ gives a 404 not found

  - by user57069

  I am trying to solve a problem where Apache stats aren't displaying correctly in Munin. I've ran through quite a bit of checks and tests regarding Munin setup, but I think my issue is related to Apache, but my skill set there is lacking. first, system info: monitored server CentOS 5.3 kernel 2.6.18-128.1.1.el5 Apache/2.2.3 "server-status" directive in httpd.conf (i've cross-compared this with another system that i did a successful parallel install of Munin on, correctly showing Apache stats, and the directive below is the same for both) ExtendedStatus On <Location /server-status> SetHandler server-status Order deny,allow Deny from all Allow from 127.0.0.1 </Location> ran lynx http://localhost/server-status got HTTP/1.1 404 taking a look at Apache access_log: 127.0.0.1 - - [13/Oct/2010:07:00:47 -0700] "GET /server-status HTTP/1.0" 404 11237 "-" "Lynx/2.8.5rel.1 libwww-FM/2.14 SSL-MM/1.4.1 OpenSSL/0.9.8e-fips-rhel5" mod_status is also loaded: % grep "mod_status" /etc/httpd/conf/httpd.conf LoadModule status_module modules/mod_status.so iptables is turned off also i did notice that the ownership status on httpd.conf on this system is root.root.. whereas the system that is displaying correctly is apache.www -- not certain that this matters?? its got to be permission issue, but i'm not certain where the permissions are messed up. any thoughts on why the test of server-status is giving me a 404?

• Can Layer Masks Achieve This Effect

  - by Julian

  If you look at the image below you will see the player surrounded by a dotted yellow box. The dotted yellow box is also part of the player and represented a portion of the player being masked from both rendering and affected by physics. My question is if layer masks in Unity can achieve the following effect. -In Area 1, the red box/animations of the player are visible and the rigidbody of this shape is affected by all Physics. -Any portion of the player that enters Area 2 makes the larger yellow box within the area become visible (and affected by physics) and vice versa for any portion of the smaller red box that enters. -This can persist when both entering and leaving either area from any direction. Thank you for any help!

• Libgdx change color of Texture at runtime [on hold]

  - by Springrbua

  i allready asked this on Stackoverflow, but i think this question may belong here. In a Libgdx game i have some Animations for my Player. All the Frames for this Animation are inside a TextureAtlas. The Player Textures show a human, with a white T-Shirt. The T-Shirt is the only white part of the Player. Now i want to be able to replace the white color with red for Player1, with green for Player2 and so on. How can i do that, without loosing the advantage of the TextureAtlas (Texture switching)? Ofc 1 way would be to store 4 versions of every Frame, for 4 different Players (colors). But there are games out there, where you can fully customize the Player, give him a blue hat, red pants and pink shirts and so on. How can this be done? Thanks a lot! EDIT: The question on Stackoverflow

• installing 12.04 failing

  - by Steve

  I just downloaded 12.04 burned it to a cd, and booted to into it on my last built computer. It loads a purple screen, then goes to a dos looking screen with a blinking cursor then loads the ubuntu loader. The lights go from red to white and finally they all turn red. This is when the entire screen goes to noise and just hangs. Seems like a hardware issue but I can successfully boot into a non genuine windows7 that I'm looking to replace. I'm not sure what to try, so any help would be appreciated. Thanks.

• Changing a Sprite When Hit in GameMaker

  - by Pixels_

  I am making a simple little Galaga style game. I want the objects sprite to change whenever it is hit. For example if a laser hits an alien then the sprite takes 1 out of 4 damage to its health points (HP). However I want the sprite to change from green to yellow after 1 hit, yellow to orange after 2 hits, orange to red after 3 hits, and red to pixel explosion after all 4 HPs are lost. That way you can easily distinguish the amount of health each alien has left. How can I do this? Preferably explain it in code.

• Wires from fan on side panel - where do they connect?

  - by Mick

  The side panel of my desktop PC has a small fan built in. There were two wires, one red one black that connected inside the PC. Unfortunately I had the bolts removed and the side door fell off ripping the cables such that the main length of cable remains attached to the fan. So there must be two short stubs of broken cable somewhere - but I can't find them! Any ideas where I should look? I can't see anything on the motherboard. the PC is running perfectly well - but I now have the side open to make sure the air can circulate. EDIT: The motherboard appears to be an "Asus P6T SE" EDIT: The manual shows the location of two "chassis fan" connectors. One is being used by a big chassis fan on the back face of the PC (underneath the pwer supply). The other appears to be unused - there is no stub of a connector with wires - its just the bare pins sticking directly out of the motherboard. There is also an unused "pwr_fan" connector. Would it be ok to simply connect the black and red wires from the fan to the black and red parts of a molex adapter?

• How does this ajax call persist DOM changes in the browser cache?

  - by Greg

  For the purpose of the question I need to create a simple fictitious scenario. I have the following trivial page with one link, call it page A: <a class="red-anchor" onclick="change_color(event);" href="http://mysite.com/b/">B</a> With the associated Javascript function: function change_color(e) { var event = e || window.event; var link = event.target; link.className = "green-anchor"; } And I have the appropriate CSS to make the anchor red or green based on the classname. This is working. That is, when I click the anchor it changes color from red to green, which is briefly visible before the browser loads page B. But if I then use the BACK button to return to page A I get different behavior in different browsers. In Safari, the anchor is still green (desired behavior) In Firefox it reverts to red I imagine that Safari is somehow updating its cached version of the page, whereas Firefox isn't. So my first question is: is there any way to get FF to update the cached page, or is something else happening here? Secondly: I have a different implementation where I use an ajax call. In this I set the class of the anchor using a session variable, something like... <a class="<?php echo $_SESSION["color"]; ?>" ...[snip]... >B</a> And the javascript function makes an additional ajax call that changes the "color" session variable. In this case both Safari and Firefox work as expected. When going back from B to A the color is still green. But I can't for the life of me figure out why it should be different to the non-ajax case. I have tried many different permutations and for it to work on FF the "color" session variable MUST change (i.e. the ajax call itself is not somehow reloading the cache). But on coming BACK, the page is being reloaded from the cache (verified in Firebug), so how is the page even accessing this session variable if it isn't reprocessing the page and running that fragment of php in the anchor? I figure there must be something fundamental here that I am not understanding. Any insight would be much appreciated.

• Manually parse string as XAML Attribute

  - by bitbonk

  How does the XAML Parser convert the string "Red" in Foreground="Red" to a SolidColorBrush? Allthough I know the Types have System.ComponentModel.TypeConverter defined, I doupt that the WPF XAML parser acutally always uses those to convert the string to the brush. Are there any XAML APIs apart from XamlReader.Load (wich wants a valid xml string) that I could use to parse a single string as if it where an attibute for a certain property?

• Color Theory: How to convert Munsell HVC to RGB/HSB/HSL

  - by Ian Boyd

  I'm looking at at document that describes the standard colors used in dentistry to describe the color of a tooth. They quote hue, value, chroma values, and indicate they are from the 1905 Munsell description of color: The system of colour notation developed by A. H. Munsell in 1905 identifies colour in terms of three attributes: HUE, VALUE (Brightness) and CHROMA (saturation) [15] HUE (H): Munsell defined hue as the quality by which we distinguish one colour from another. He selected five principle colours: red, yellow, green, blue, and purple; and five intermediate colours: yellow-red, green-yellow, blue-green, purple-blue, and red-purple. These were placed around a colour circle at equal points and the colours in between these points are a mixture of the two, in favour of the nearer point/colour (see Fig 1.). VALUE (V): This notation indicates the lightness or darkness of a colour in relation to a neutral grey scale, which extends from absolute black (value symbol 0) to absolute white (value symbol 10). This is essentially how ‘bright’ the colour is. CHROMA (C): This indicates the degree of divergence of a given hue from a neutral grey of the same value. The scale of chroma extends from 0 for a neutral grey to 10, 12, 14 or farther, depending upon the strength (saturation) of the sample to be evaluated. There are various systems for categorising colour, the Vita system is most commonly used in Dentistry. This uses the letters A, B, C and D to notate the hue (colour) of the tooth. The chroma and value are both indicated by a value from 1 to 4. A1 being lighter than A4, but A4 being more saturated than A1. If placed in order of value, i.e. brightness, the order from brightest to darkest would be: A1, B1, B2, A2, A3, D2, C1, B3, D3, D4, A3.5, B4, C2, A4, C3, C4 The exact values of Hue, Value and Chroma for each of the shades is shown below (16) So my question is, can anyone convert Munsell HVC into RGB, HSB or HSL? Hue Value (Brightness) Chroma(Saturation) === ================== ================== 4.5 7.80 1.7 2.4 7.45 2.6 1.3 7.40 2.9 1.6 7.05 3.2 1.6 6.70 3.1 5.1 7.75 1.6 4.3 7.50 2.2 2.3 7.25 3.2 2.4 7.00 3.2 4.3 7.30 1.6 2.8 6.90 2.3 2.6 6.70 2.3 1.6 6.30 2.9 3.0 7.35 1.8 1.8 7.10 2.3 3.7 7.05 2.4 They say that Value(Brightness) varies from 0..10, which is fine. So i take 7.05 to mean 70.5%. But what is Hue measured in? i'm used to hue being measured in degrees (0..360). But the values i see would all be red - when they should be more yellow, or brown. Finally, it says that Choma/Saturation can range from 0..10 ...or even higher - which makes it sound like an arbitrary scale. So can anyone convert Munsell HVC to HSB or HSL, or better yet, RGB?

• Ruby concatenate strings and add spaces

  - by David Oneill

  I have 4 string variables name, quest, favorite_color, speed that might be empty. I want to concatenate them all together, putting spaces between those that aren't empty. So: name = 'Tim' quest = 'destroy' favorite_color = 'red' speed = 'fast' becomes 'Tim destroy red fast' and name = 'Steve' quest = '' favorite_color = '' speed = 'slow' becomes: 'Steve slow' (Notice: there is only 1 space between 'Steve' and 'slow') How do I do that (preferably in 1 line).

• place and show pixel in the Cartesian plane graph in JavaFX

• Android - incremental status bar notification icon

  - by DroidIn.net

  You know what I'm talking about: for example when you get multiple new emails the notification icon in the status bar is augmented with a little red circle that contains number of unread mails. Twitroid has the same icon. Any idea how it's done? I don't think (or so I hope) there are 10000 similar icons. Is this red circle generated and overlaid the notification icon? If so - any code snippets will be much appreciated.

• Rush Hour - Solving the game

  - by Rubys

  Rush Hour if you're not familiar with it, the game consists of a collection of cars of varying sizes, set either horizontally or vertically, on a NxM grid that has a single exit. Each car can move forward/backward in the directions it's set in, as long as another car is not blocking it. You can never change the direction of a car. There is one special car, usually it's the red one. It's set in the same row that the exit is in, and the objective of the game is to find a series of moves (a move - moving a car N steps back or forward) that will allow the red car to drive out of the maze. I've been trying to think how to solve this problem computationally, and I can really not think of any good solution. I came up with a few: Backtracking. This is pretty simple - Recursion and some more recursion until you find the answer. However, each car can be moved a few different ways, and in each game state a few cars can be moved, and the resulting game tree will be HUGE. Some sort of constraint algorithm that will take into account what needs to be moved, and work recursively somehow. This is a very rough idea, but it is an idea. Graphs? Model the game states as a graph and apply some sort of variation on a coloring algorithm, to resolve dependencies? Again, this is a very rough idea. A friend suggested genetic algorithms. This is sort of possible but not easily. I can't think of a good way to make an evaluation function, and without that we've got nothing. So the question is - How to create a program that takes a grid and the vehicle layout, and outputs a series of steps needed to get the red car out? Sub-issues: Finding some solution. Finding an optimal solution (minimal number of moves) Evaluating how good a current state is Example: How can you move the cars in this setting, so that the red car can "exit" the maze through the exit on the right?
