• General purpose ticketing/tech support system [closed]

  - by crazybyte

  Possible Duplicate: What’s your favorite ticketing system? I was wondering if somebody could recommend me a very user friendly or simple general purpose ticketing/tech support system. I need something that is web based, preferably open-sourced/free software implemented using PHP, Ruby, Ruby on Rails or Java (as back end) with MySQL or PostgreSQL as database engine. I need something that is not development management oriented or project management oriented like Eventum or similar (random example), something to which the user can connect open a tech support request and be able to follow it until is solved or dropped.I need it to be open-sourced to be able to modify it if there is a need or extend it. I tried a number of such systems available and I found that osTicket or eTicket is something that it's close to what I need, but the code is somewhat flaky and some of the features are working badly or behaving strangely. Any thoughts/advice where to find something similar? Thanks!

• Build Advise for Home Web/NAS Server with Ubuntu Server 12.04 [closed]

  - by razor7

  I need to have a personal Webserver with NAS capabilities. The Webserver to test some LAMP projects I develop for clients, and also NAS to be able to stream media to local network. I want to have full control of the box, so I'm planning to build it with some spare parts and Ubuntu Server. The services/software that will run are (remember, is for personal and testing use only): SAMBA/CIFS SSH Server Apache 2 MySQL 5 Mercurial Repo PHP 5.3 Ruby on Rails OwnCloud Dovecot Webmin Postfix PureFTPd ClamAV The Hardware: Intel Dual Core E2180 2.0 GHz MSI P35 Neo Kinkston 1GB DDR2, 667 MSI Nvidia 7300le PCIe x16 256mb RAM HDD SATA WD Green 2TB x2 (RAID-1 with MDADM RAID Controller) 16 GB USB Pendrive (For server system installation) My idea is to build this system, using the pendrive for the Ubuntu Server software, and packages, and the RAID-1 for gross data storage. What do you think? Thanks a lot!

• Modular Inverse and BigInteger division

  - by dano82

  I've been working on the problem of calculating the modular inverse of an large integer i.e. a^-1 mod n. and have been using BigInteger's built in function modInverse to check my work. I've coded the algorithm as shown in The Handbook of Applied Cryptography by Menezes, et al. Unfortunately for me, I do not get the correct outcome for all integers. My thinking is that the line q = a.divide(b) is my problem as the divide function is not well documented (IMO)(my code suffers similarly). Does BigInteger.divide(val) round or truncate? My assumption is truncation since the docs say that it mimics int's behavior. Any other insights are appreciated. This is the code that I have been working with: private static BigInteger modInverse(BigInteger a, BigInteger b) throws ArithmeticException { //make sure a >= b if (a.compareTo(b) < 0) { BigInteger temp = a; a = b; b = temp; } //trivial case: b = 0 => a^-1 = 1 if (b.equals(BigInteger.ZERO)) { return BigInteger.ONE; } //all other cases BigInteger x2 = BigInteger.ONE; BigInteger x1 = BigInteger.ZERO; BigInteger y2 = BigInteger.ZERO; BigInteger y1 = BigInteger.ONE; BigInteger x, y, q, r; while (b.compareTo(BigInteger.ZERO) == 1) { q = a.divide(b); r = a.subtract(q.multiply(b)); x = x2.subtract(q.multiply(x1)); y = y2.subtract(q.multiply(y1)); a = b; b = r; x2 = x1; x1 = x; y2 = y1; y1 = y; } if (!a.equals(BigInteger.ONE)) throw new ArithmeticException("a and n are not coprime"); return x2; }

• mysql query not running correctly from inside the application

  - by Mala

  I am completely stumped. Here is my php (CodeIgniter) code: function mod() { $uid = $this->session->userdata('uid'); $pid = $this->input->post('pid'); if ($this->_verify($uid,$pid)) { $name = $this->input->post('name'); $price = $this->input->post('price'); $curr = $this->input->post('curr'); $url = $this->input->post('url'); $query = $this->db->query("UPDATE items SET name=".$this->db->escape($name).", price=".$this->db->escape($price).", currency=".$this->db->escape($curr),", url=".$this->db->escape($url)." WHERE pid=".$this->db->escape($pid)." LIMIT 1"); } header('location: '.$this->session->userdata('current')); } The purpose of this code is to modify the properties (name, price, currency, url) of a row in the 'items' table (priary key is pid). However, for some reason, allowing this function to run once modifies the name, price, currency and url of ALL entries in the table, regardless of their pid and of the LIMIT 1 thing I tacked on the end of the query. It's as if the last line of the query is being completely ignored. As if this wasn't strance enough, I replaced "$query = $this->db->query(" with an "echo" to see the SQL query being run, and it outputs a query much like I would expect: UPDATE items SET name='newname', price='newprice', currency='newcurrency', url='newurl' WHERE pid='10' LIMIT 1 Copy-pasting this into a MySQL window acts exactly as I want: it modifies the row with the selected pid. What is going on here???

• How to break out from nested doseqs

  - by fizbin

  Hi, I have a question regarding nested doseq loops. In the start function, once I find an answer I set the atom to true, so that the outer loop validation with :while fails. However it seems that it doesn't break it, and the loops keep on going. What's wrong with it? I am also quite confused with the usage of atoms, refs, agents (Why do they have different names for the update functions when then the mechanism is almost the same?) etc. Is it okay to use an atom in this situation as a flag? Obviously I need a a variable like object to store a state. (def pentagonal-list (map (fn [a] (/ (* a (dec (* 3 a))) 2)) (iterate inc 1))) (def found (atom false)) (defn pentagonal? [a] (let [y (/ (inc (Math/sqrt (inc (* 24 a)))) 6) x (mod (* 10 y) 10)] (if (zero? x) true false))) (defn both-pent? [a b] (let [sum (+ b a) diff (- a b)] (if (and (pentagonal? sum) (pentagonal? diff)) true false))) (defn start [] (doseq [x pentagonal-list :while (false? @found)] (doseq [y pentagonal-list :while (<= y x)] (if (both-pent? x y) (do (reset! found true) (println (- x y)))))))

• Why is DivMod Limited to Words (<=65535)?

  - by Andreas Rejbrand

  In Delphi, the declaration of the DivMod function is procedure DivMod(Dividend: Cardinal; Divisor: Word; var Result, Remainder: Word); Thus, the divisor, result, and remainder cannot be grater than 65535, a rather severe limitation. Why is this? Why couldn't the delcaration be procedure DivMod(Dividend: Cardinal; Divisor: Cardinal; var Result, Remainder: Cardinal); The procedure is implemented using assembly, and is therefore probably extremely fast. Would it not be possible for the code PUSH EBX MOV EBX,EDX MOV EDX,EAX SHR EDX,16 DIV BX MOV EBX,Remainder MOV [ECX],AX MOV [EBX],DX POP EBX to be adapted to cardinals? How much slower is the naïve attempt procedure DivModInt(const Dividend: integer; const Divisor: integer; out result: integer; out remainder: integer); begin result := Dividend div Divisor; remainder := Dividend mod Divisor; end; that is not (?) limited to 16-bit integers?

• How to analyze evenness/oddness of numbers in Java

  - by appreciation

  I have to write a program which reads in 3 numbers (using input boxes), and depending on their values it should write one of these messages: All 3 numbers are odd OR All 3 numbers are even OR 2 numbers are odd and 1 is even OR 1 number is odd and 2 are even This is what I have so far: import javax.swing.JOptionPane; class program3 { public static void main(String[] args) { String num1 = JOptionPane.showInputDialog("Enter first number."); String num2 = JOptionPane.showInputDialog("Enter second number."); String num3 = JOptionPane.showInputDialog("Enter third number."); boolean newnum1 = Integer.parseInt(num1); boolean newnum2 = Integer.parseInt(num2); boolean newnum3 = Integer.parseInt(num3); } } This is where I am stuck. I am not sure how to use the MOD to display the messages. I think I have to also use an IF Statement too...But I'm not too sure. Please help! :D

• Making A Dynaically Created Excel Report Downloadable

  - by Nick LaMarca

  I have 2 blocks of code, if someone could help me put them together I would get the functionality I am looking for. The first block of code downloads a gridview to excel using the download dialog I am looking for: Public Overloads Overrides Sub VerifyRenderingInServerForm(ByVal control As Control) ' Verifies that the control is rendered End Sub Private Sub ExportToExcel(ByVal filename As String, ByVal gv As GridView, ByVal numOfCol As Integer) Response.Clear() Response.Buffer = True Response.AddHeader("content-disposition", String.Format("attachment; filename={0}", filename)) Response.Charset = "" Response.ContentType = "application/vnd.ms-excel" Dim sw As New StringWriter() Dim hw As New HtmlTextWriter(sw) gv.AllowPaging = False gv.DataBind() 'Change the Header Row back to white color gv.HeaderRow.Style.Add("background-color", "#FFFFFF") For i As Integer = 0 To numOfCol - 1 gv.HeaderRow.Cells(i).Style.Add("background-color", "blue") gv.HeaderRow.Cells(i).Style.Add("color", "#FFFFFF") Next For i As Integer = 0 To gv.Rows.Count - 1 Dim row As GridViewRow = gv.Rows(i) 'Change Color back to white row.BackColor = System.Drawing.Color.White For j As Integer = 0 To numOfCol - 1 row.Cells(j).Style.Add("text-align", "center") Next 'Apply text style to each Row row.Attributes.Add("class", "textmode") 'Apply style to Individual Cells of Alternating Row If i Mod 2 <> 0 Then For j As Integer = 0 To numOfCol - 1 row.Cells(j).Style.Add("background-color", "#CCFFFF") row.Cells(j).Style.Add("text-align", "center") '#C2D69B 'row.Cells(j).Style.Add("font-size", "12pt") Next End If Next gv.RenderControl(hw) 'style to format numbers to string Dim style As String = "<style> .textmode { mso-number-format:\@; } </style>" Response.Write(style) Response.Output.Write(sw.ToString()) Response.Flush() Response.End() End Sub The second block of code is a sample report I am wish to be downloaded. So instead of downloading a gridview I want this function to accept a worksheet object.

• Web scrapping from a Google Chrome extension

  - by limoragni

  I've started to develop a Chrome extension to navigate and prform actions on a website. Until now the extension is able to receive a couple of parameters and check a set of radio-buttons, fill in a few inputs of a form and then submit it. What I want to do now is to repeat the process, but I'm stuck when the page is reloaded. And I don't know how can I do to make the script reacts to the finish of the request. The workflow I want to achieve is the following (is for automaticly copying a certain object): Popup side Enter the number of the Master object to copy Enter the base name of the copies (example Mod, so the I can iterate and add mod1, mod2, modn) Enter the number of copies Background side Select master Select standard options Fill in inputs Submit form Wait for the page to complete the request and continue to the next copy. (here I need help) The problem is on the repetition, the rest is taking care of. I assume that must be a way of dealing with requests. Any ideas? By the way I'm doing it all with the extension and tabs methods of google chrome plus javascript and jquery.

• Complexity of subset product

  - by threenplusone

  I have a set of numbers produced using the following formula with integers 0 < x < a. f(x) = f(x-1)^2 % a For example starting at 2 with a = 649. {2, 4, 16, 256, 636, 169, 5, 25, 649, 576, 137, ...} I am after a subset of these numbers that when multiplied together equals 1 mod N. I believe this problem by itself to be NP-complete (based on similaries to Subset-Sum problem). However starting with any integer (x) gives the same solution pattern. Eg. a = 649 {2, 4, 16, 256, 636, 169, 5, 25, 649, 576, 137, ...} = 16 * 5 * 576 = 1 % 649 {3, 9, 81, 71, 498, 86, 257, 500, 135, 53, 213, ...} = 81 * 257 * 53 = 1 % 649 {4, 16, 256, 636, 169, 5, 25, 649, 576, 137, 597, ...} = 256 * 25 * 137 = 1 % 649 I am wondering if this additional fact makes this problem solvable faster? Or if anyone has run into this problem previously or has any advice?

• Emacs equivalent of this Vim command to run my tests?

  - by eightbitraptor

  I'm using Emacs at the moment and experimenting with it for my Rails development and there is one thing that I do quite regularly in Vim and I'd like to know if an equivalent exists in Emacs, or an alternative workflow to achieve the behavior that I need. The command in Vim is :map ;t :!rspec --no-color %<cr> Essentially this maps a key combination to run a bash/shell command on the file represented by the current buffer (% expands to the filename at runtime, the <cr> is just a carriage return at the end to execute the command). I map all sorts of random little commands as and when I need them and I really miss the immediacy of this approach. How can I achieve something similar?

• Need some help setting up subdomains for my site

  - by KarimSaNet

  I'm setting up my website and want to have it so all subdomain requests are rewritten to the appropriate subdirectory. For example http://projects.karimsa.net/ -> http://karimsa.net/projects/ But I want to use the Apache rewrite mod to do this so that the URL in the browser stays the same. Here is what my config looks like at the moment: ## rewrite subdomains RewriteEngine On RewriteCond %{HTTP_HOST} ^(.*).karimsa.net RewriteCond %{HTTP_HOST} !^www.karimsa.net [NC] RewriteRule ^(.*)$ http://karimsa.net/%1/$1 [R=301,L] And my CNAME records on 'projects.karimsa.net': Domain TTL Data Type projects.karimsa.net 14400 karimsa.net CNAME Theoretically, I feel this should work. But when I go to the URL, it gives me a server misconfiguration error, my provider's default webpage. What I should see is the index.php under /projects/. What am I doing wrong? Any help would be appreciated, thanks for reading. Addition: I realized I forgot to mention some of the problem. The domain 'karimsa.net' is parked at 'karimsa.x10.mx'. If I set up the same configuration on 'projects.karimsa.x10.mx', the rewrite and CNAME work. But on the parked domain I still get the default webpage.

• Drupal 7 - I can't pass post data in module function

  I can't pass post data in my custom module. filenames: mymodule.info mymodule.mod .info name = My Module description = My custom module. package = DEV version = 1.0 core = 7.x .module <?php function mymodule_menu() { $items = array(); $items['getcountries'] = array( 'title' => 'Get Countries', 'page callback' => 'getcountries', 'access arguments' => array('access content'), 'type' => MENU_CALLBACK, ); $items['getstates'] = array( 'title' => 'Get States', 'page callback' => 'getstates', 'access arguments' => array('access content'), 'type' => MENU_CALLBACK, ); return $items; } function getcountries() { $result = db_query("select distinct(country) from region"); $jsonarray = Array(); foreach ($result as $record) { $jsonarray[] = array( 'item' => $record->country, 'value' => $record->country ); } $json = json_encode($jsonarray); echo $json; } function getstates() { echo $_POST["test"]; } Ajax call $(document).ready(function(){ $.ajax({ url: '/getstates', type: 'POST', data: '{"test":"1"}', success : function () { alert('ok'); }, error : function (jqXHR, textStatus, errorThrown) { alert('error'); } }); }); The first item "getcountries" is working fine however the second one is not. I can browse to http://mysite.com/getstates ok but when I call this function using ajax it is not passing the value of "test" which is "1" to $_POST["test"]. I am new to Drupal so I am positive that I miss something here. I thought I need a new set of eyes.

• LocationMatch Regex for versioning

  - by Aventus

  I've tried using the docs but I'm quite new to regex. I've had success with others but the same method is not working for what I'm actually after. I'm trying to send users to different servers based on the version number in the URL. This this case, older versions are to be sent to the new server for a particular service. <LocationMatch "/(1.0|2.0|3.0)/appname"> ... </LocationMatch> The following is working - <LocationMatch "/1/appname"> ... </LocationMatch> <LocationMatch "/2/appname"> ... </LocationMatch> What I would love to achieve is sending all those major releases with a single tag - <LocationMatch "/(1*|2*|3*)/appname"> ... </LocationMatch> I've already referred the documentation at http://httpd.apache.org/docs/2.2/mod/core.html#locationmatch but unfortunately it doesn't cover my case with enough detail to help me.

• Failling install Ralink RT5592 driver on Ubuntu 14.04 LTS

  - by atisou

  My problem concerns the installation of a wi-fi driver (RT5592) for my new wi-fi adapter (PCE-N53) on my newly built computer. Basically, I don't manage to get the driver installed and therefore I cannot get the wifi to work. I know I am not the only one having this issue this year, between RT5592 driver and Ubuntu 14.04 LTS, in one way or the other. Is there anybody who has ever been able to fix this problem? It does not look like on all the posts I have been through... Following an answer to a same problem as mine (I was getting the same error message as Christopher Kyle Horton of "incompatible types" etc), I have applied the instructions and done the editings in a script as suggested by Paul B. Unfortunately I still do get error/warnings message (a different one this time) at the end of the make and the wi-fi still does not work. Below is a snapshot of the end of the message: In file included from /home/username/Downloads/PCE-N53/Linux/DPO_GPL_RT5592STA_LinuxSTA_v2.6.0.0_20120326/include/os/rt_linux.h:31:0, from /home/username/Downloads/PCE-N53/Linux/DPO_GPL_RT5592STA_LinuxSTA_v2.6.0.0_20120326/include/rtmp_os.h:44, from /home/username/Downloads/PCE-N53/Linux/DPO_GPL_RT5592STA_LinuxSTA_v2.6.0.0_20120326/include/rtmp_comm.h:69, from /home/username/Downloads/PCE-N53/Linux/DPO_GPL_RT5592STA_LinuxSTA_v2.6.0.0_20120326/os/linux/../../os/linux/pci_main_dev.c:31: include/linux/module.h:88:32: error: ‘__mod_pci_device_table’ aliased to undefined symbol ‘rt2860_pci_tbl’ extern const struct gtype##_id __mod_##gtype##_table \ ^ include/linux/module.h:146:3: note: in expansion of macro ‘MODULE_GENERIC_TABLE’ MODULE_GENERIC_TABLE(type##_device,name) ^ /home/username/Downloads/PCE-N53/Linux/DPO_GPL_RT5592STA_LinuxSTA_v2.6.0.0_20120326/os/linux/../../os/linux/pci_main_dev.c:73:1: note: in expansion of macro ‘MODULE_DEVICE_TABLE’ MODULE_DEVICE_TABLE(pci, rt2860_pci_tbl); ^ cc1: some warnings being treated as errors make[2]: *** [/home/username/Downloads/PCE-N53/Linux/DPO_GPL_RT5592STA_LinuxSTA_v2.6.0.0_20120326/os/linux/../../os/linux/pci_main_dev.o] Error 1 make[1]: *** [_module_/home/username/Downloads/PCE-N53/Linux/DPO_GPL_RT5592STA_LinuxSTA_v2.6.0.0_20120326/os/linux] Error 2 make[1]: Leaving directory `/usr/src/linux-headers-3.13.0-32-generic' make: *** [LINUX] Error 2 The full pastebin data: paste.ubuntu.com/8088834/ It looks from the message that one would need to edit manually some of/other scripts in the driver package, as did Paul B suggest in one case.

If this is a kernel version (I have 3.13.0-32-generic) incompatibility issue with the driver as chilli555 suggests (the README file in the driver package says indeed it is compatible with kernel 2.6), how could one trick this around to make it work? that should be possible right? On ubuntu forums, the patches proposed dont work (leads the computer to freeze). Basically: is there anybody out there who has ever been able to make a PCE-N53 work on Ubuntu 14.04 LTS (kernel 3.13)? how shall I edit the driver package to make it work for my kernel?

• Social Network Stalking

  - by David Dorf

  Think about this: By reading this blog, you and I are connected. We have this blog and its topics in common, so there's a chance we have other things in common as well. In any relationship there is a degree of trust and influence. If you trust me, at least in terms of particular subjects, then I have some influence over you. If I buy an iPad, then there's an opportunity for me to influence your possible purchase of an over-hyped tablet that you don't really need. So what could a retailer do with this? Retailers that have fans and followers should assume that the friends of those fans and followers are more susceptible to their marketing efforts. If I'm a fan of Apple, then Apple will be more successful marketing to my friends than marketing to random people. Intuitively that makes sense, at least to me. Companies like 33Across and Pursway are already putting this theory into practice, and achieving some interesting results. Jeff Jarvis, who by-the-way is speaking at CrossTalk this year, has been discussing the power of influencers in social networks. In his blog he rails against marketers and says "messages and influence aren't the future of marketing; conversations and relationships are." Valuable messages will be passed on because they are valuable, not because someone has the power to exert influence. True enough, but that won't stop the efforts underway to leverage social networks for more targeted advertising. From a business perspective, this sounds like a goldmine to me; on a personal level, it's a bit creepy.

• Would Java programmers hire C# programmers?

  - by Linx

  I learned and used Java in college. After graduating, I got a job in C#. Two years after, there are a lot more positions in Java. Would I have a good chance to be hired as a Java programmer? What interview questions would I be asked? Update (07/10/2012): Thank you for all your answers and comments. I really appreciate it. I had a chance to work on a Java project for 9 months. It was with a mix of Perl because we were trying to migrate from Perl to Java. Eclipse has definitely improved a lot. I used Maven and Spring MVC. Pretty fun. So, after the project ended, I did Ruby on Rails. That was a year-long fun project also. Two years later, I am back to .NET. Overall, being a programmer has been very sweet. Wouldn't trade it for anything else!

• Want to learn/dive into Java Web Development—where to start?

  - by ernesto che

  Hi folks, I want to dive into Java Web Development, but I don’t know where to start because I am overwhelmed with Frameworks, JSRs, modules and the like. Coming from a PHP and Ruby (on Rails) background, it may seem awkward to go the other way ’round—still there are a lot of places where Java is (and probably will be) prevalent. I know basic Java concepts, syntax and OOP, and I have done (too much) nonsense in existing projects in JSP. I am already using SVN and GIT, but like coding PHP and Ruby mostly via VIM, i’ve also done versioning from the command line. But this time I want to learn to build a new project from the ground up, in a more, let’s say, academic way (instead of the hackery to date). Looking at e. g. Eclipse frightens me. Then there is Struts, Spring, JPA, Hibernate, Seam, just to throw in some buzzwords, that I cannot put into clear relation to each other. Can you point me to some tutorials or books that could help me? What are the technologies you absolutely have to know, the JSRs that are widely implemented in the industry? Or, if you are an employer: What does a “Junior Java Web developer” have to know? Thanks for your suggestions!

• puppet rspec no such file to load -- rspec-puppet (LoadError)

  - by Vorsprung

  I have no prior experience at all of ruby. I am not interested in ruby (and so have no knowledge of rails etc) as such but am using puppet to manage a group of servers. I have written some modules and the rspec-puppet system looks like it would be very useful. However, I cannot get rspec-puppet to work I am using Ubuntu LTS 10.04 I have installed puppet rspec using the directions on their web page What I actually did apt-get install rubygems # (installs 1.8) gem install rspec-expectations gem install rspec-puppet I also installed librspec-ruby1.8 Then I ran rspec-puppet-init in a puppet module directory I'd already made (it's a working puppet module) I made a file as defined in the tutorial $ more spec/defines/rule_spec.rb require 'spec_helper' describe 'vanusers::rule' do let(:title) { 't1' } it { should contain_class('vanusers::JamieA') } end but when I try and run it there is a mysterious dependancy issue $ spec spec/defines/rule_spec.rb /home/jamie/git/puppet/modules/vanusers/spec/spec_helper.rb:1:in `require': no such file to load -- rspec-puppet (LoadError) from /home/jamie/git/puppet/modules/vanusers/spec/spec_helper.rb:1 from ./spec/defines/rule_spec.rb:1:in `require' from ./spec/defines/rule_spec.rb:1 from /usr/lib/ruby/1.8/spec/runner/example_group_runner.rb:15:in `load' from /usr/lib/ruby/1.8/spec/runner/example_group_runner.rb:15:in `load_files' from /usr/lib/ruby/1.8/spec/runner/example_group_runner.rb:14:in `each' from /usr/lib/ruby/1.8/spec/runner/example_group_runner.rb:14:in `load_files' from /usr/lib/ruby/1.8/spec/runner/options.rb:132:in `run_examples' from /usr/lib/ruby/1.8/spec/runner/command_line.rb:9:in `run' from /usr/bin/spec:3 Here is the solution I came up with in the end:: apt-get install rubygems gem install rspec-expectations rspec-puppet puppet-lint puppetlabs_spec_helper so your path picks up the gem stuff export PATH=/var/lib/gems/1.8/bin:$PATH cd into module and rm spec/spec_helper.rb rspec-puppet-init replace Rakefile with require 'rake' require 'rspec/core/rake_task' require 'puppetlabs_spec_helper/rake_tasks' Then "rake spec" to run tests or "rake lint" to check files http://sysadvent.blogspot.co.uk/2013/12/day-22-getting-started-testing-your.html was an excellent source of info

• Advice for a computer science sophomore in college?

  - by RDas

  Hi Everyone! I'm a sophomore in college majoring in Computer Science and Math. I have always loved programming. I started programming in C when I was nine years old and over the years I've picked up Visual Basic, C#, Java, C++, JavaScript, Objective-C, Python, Ruby, elementary Haskell and elementary Erlang, and I learned Perl back in the day which I've mostly forgotten. I have not done much network programming. I have done CGI programming, but that was about six/seven years ago. I've done some socket programming and written (school) programs to do interprocess communication, which I understood and liked. I'm taking a course on client/server programming and another one on network security next semester, which I am really looking forward to. I'm seeking advice on how to proceed with future learning. I've mostly done application (mobile and desktop) development, not much of web development. I'd like to pick up some web development this coming semester. Since I know Ruby and Python, should I start by learning Django and/or Rails? Any other suggestions on starting web development? I have a good understanding of HTML and CSS. Also, I'd also like to know how hard it is to pick up and be good (read: productive) in functional programming languages coming from a purely structured/object oriented background? I've been reading up on Erlang and Haskell, and I'd like to know your opinions on whether it's worth my time trying to learn them. What about Lisp, Scheme and other functional languages? Any help/ideas would be really appreciated.

• How To Delete Built-in Windows 7 Power Plans (and Why You Probably Shouldn’t)

  - by The Geek

  Do you actually use the Windows 7 power management features? If so, have you ever wanted to just delete one of the built-in power plans? Here’s how you can do so, and why you probably should leave it alone. Just in case you’re new to the party, we’re talking about the power plans that you see when you click on the battery/plug icon in the system tray. The problem is that one of the built-in plans always shows up there, even if you only use custom plans. When you go to “More power options” on the menu there, you’ll be taken to a list of them, but you’ll be unable to get rid of any of the built-in ones, even if you have your own. You can actually delete the power plans, but it will probably cause problems, so we highly recommend against it. If you still want to proceed, keep reading. Delete Built-in Power Plans in Windows 7 Open up an Administrator mod command prompt by right-clicking on the command prompt and choosing “Run as Administrator”, then type in the following command, which will show you a whole list of the plans. powercfg list Do you see that really long GUID code in the middle of each listing? That’s what we’re going to need for the next step. To make it easier, we’ll provide the codes here, just in case you don’t know how to copy to the clipboard from the command prompt. Power Scheme GUID: 381b4222-f694-41f0-9685-ff5bb260df2e  (Balanced) Power Scheme GUID: 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c  (High performance)Power Scheme GUID: a1841308-3541-4fab-bc81-f71556f20b4a  (Power saver) Before you do any deleting, what you’re going to want to do is export the plan to a file using the –export parameter. For some unknown reason, I used the .xml extension when I did this, though the file isn’t in XML format. Moving on… here’s the syntax of the command: powercfg –export balanced.xml 381b4222-f694-41f0-9685-ff5bb260df2e This will export the Balanced plan to the file balanced.xml. And now, we can delete the plan by using the –delete parameter, and the same GUID.  powercfg –delete 381b4222-f694-41f0-9685-ff5bb260df2e If you want to import the plan again, you can use the -import parameter, though it has one weirdness—you have to specify the full path to the file, like this: powercfg –import c:\balanced.xml Using what you’ve learned, you can export each of the plans to a file, and then delete the ones you want to delete. Why Shouldn’t You Do This? Very simple. Stuff will break. On my test machine, for example, I removed all of the built-in plans, and then imported them all back in, but I’m still getting this error anytime I try to access the panel to choose what the power buttons do: There’s a lot more error messages, but I’m not going to waste your time with all of them. So if you want to delete the plans, do so at your own peril. At least you’ve been warned!
