  • what will EcmaScript 6 bring to the table for us

    - by user697296
    Our company ported moderate chunks of business logic to JavaScript. We compile the code with a minifier, which further improves performance. Since the language is dynamically typed, it lends itself well to obfuscation, which occurs as a byproduct of minification. We went to great efforts to ensure it positively screams, performance-wise. We can now do what we did before, faster, better, with less code, on more platforms. In summary, we are very satisfied with the current state of the language. I personally love the language especially for its cross-platform nature. So naturally, I read up a lot about the state of JavaScript compilers, performance and compatibility across as many browsers and platforms as I have time to research. The one theme which has been growing louder and louder these days, is the news about ECMAScript 6. So far, what I have been able to gather is that ES6 promises a better development experience; firstly by enabling new ways to do things, secondly by reporting errors early. This sounds great for those who are still waiting for the language to meet their needs before jumping on board. But we have already jumped on board in a big way. Sure, I expect that we will have to do ongoing maintenance and feature revisions on our code through the years, and that we would obviously make use of best practices at the time. But I don't see us refactoring major portions of it to take advantage of language features that are mostly intended to boost developer productivity. I keep wondering, what impact will the language advances ultimately have on our existing, well-written, well-performing code base? Is there something I am missing? Is there something we ought to look out for? Does anyone have tips or guidance on how we should approach the ecmascript.next finalization? Should we care?

  • How do web servers enforce the same-origin policy?

    - by BBnyc
    I'm diving deeper into developing RESTful APIs and have so far worked with a few different frameworks to achieve this. Of course I've run into the same-origin policy, and now I'm wondering how web servers (rather than web browsers) enforce it. From what I understand, some enforcing seems to happen on the browser's end (e.g., honoring a Access-Control-Allow-Origin header received from a server). But what about the server? For example, let's say a web server is hosting a Javascript web app that accesses an API, also hosted on that server. I assume that server would enforce the same-origin policy --- so that only the javascript that is hosted on that server would be allowed to access the API. This would prevent someone else from writing a javascript client for that API and hosting it on another site, right? So how would a web server be able to stop a malicious client that would try to make AJAX requests to its api endpoints while claiming to be running javascript that originated from that same web server? What's the way most popular servers (Apache, nginx) protect against this kind of attack? Or is my understanding of this somehow off the mark? Or is the cross-origin policy only enforced on the client end?

  • Tunneling through SSH for 1521 port access?

    - by A T
    I am developing locally on my computer, using my own Apache server with PHP configured. My database however is remotely located on an Oracle 11g Database Server. We were also given a separate remote server for hosting our .html and .php files, however only FTP access has been provided there. Development is far too slow waiting for the FTP connection to push. So I decided to develop locally, but still use the remote DB server. Unfortunately that gives me an error. Not sure how—or where—to integrate tunnelling. Do I add something to the oci_connect HOST in my PHP file, or do I encapsulate my whole environment over SSH?

  • Microsoft word 2003 when I am making deletions or changes they show up on the document in a balloon

    - by Cyberdude
    I am writing a novel in microsoft word 2003, and I am pretty far into it, but one time I hit a one of the F keys (I don't know which one) by accident. Now everytime I go on word I have these stupid balloons with writing in them and all my deletions and everything are highlighted shown. I looked up on google how to stop this and I did as it says, and it worked the balloon with the deletions and all the changes dissapeared, but next time I opened up the document they were back, and they always keep coming back, so when I send my document to anyone it shows them all my deletions and changes I made to the document. Can anyone help please. Thanks

  • HDMI & Display Port stopped work on 11.10

    - by dizzy
    After upgraded two laptops to 11.10, HDMI and Display ports stopped to work. Symptoms on each (btw. it used to work with 11.04 on both): laptop Dell Inspiron 1525 (HDMI, Intel GMX 3100): after HDMI cable is plugged in, screen is corrupted (no panel, no icons), system is unresponsive, TV set receives some signal, but only blue screen and some regular ticks can be heard. Unplugging the cable system recovers. No logs were checked. Thinkpad W510 (DisplayPort, NVidia). Simple "Screens" utility does not recognizes TV set, but this is something to do with the differences between Nvidia driver API and the one expected from the utility, as far I could spot on the net. However, using Nvidia-settings, TV is recognized, but cannot be enabled and used. Beside that, touch pad freezes after HDMI2DisplayPort connector is plugged in the laptop (not immediately, but after few seconds - probably after some handshake with the TV set crashes). It is strange that no such bug reports can be found on the net. So, I guess it is something wrong on our laptops only, but would appreciate some hints (i.e. any known changes recently related to HDMI, Display Port, X-Windows, kernel... wherever I should take a look and fix the issue).

  • How to monitor nginx proxy cache?

    - by Isaac
    I would like to see which objects get cached by my nginx reverse proxy (with an apache as a backend). So far I could not find a way, only the info that its not implemented yet. The reason is that I would like to tweak my configuration for best performance without putting too much stress on the server, as the backend is a production system. I know benchmarking would be better, but its not an option right now. So I though an alternative measure would be to monitor the cache. Is that possible, and if yes, how? (despite patching nginx with the patch mentioned in the link above)

  • Software RAID underneath ESXi datastore

    - by carlpett
    I'm building an virtual environment for a small business. It is based around a single ESXi 5.1 host, which will host half a dozen or so VMs. I'm having some doubts regarding how to implement the storage though. I naturally want the datastore to be fault tolerant, but I can't get the funds for a separate storage machine, nor expensive hardware RAID solutions, so I would like to use some software RAID (lvm/mdadm, most likely). How can this be implemented? My only idea so far would be to create a VM which has the storage adapter as passthrough, puts some software RAID on top of the disks and then presents the resulting volumes "back" to the ESXi host which then creates a datastore from which other VMs get their storage presented. This does seem kind of round-about, do I have any better options? From my research, passthrough seems to come with quite a few drawbacks, such as no suspend/resume etc.

  • Is it possible to change User's Home Directorys permission in OSX?

    - by Sosiska
    Most of your staff uses OSX as main operation system. The problem is that recently we were attacked with some odd malware: users are getting zip-file via mail, and when they open this zip file, they execute a binary keylogger malware, that is inside this zipped file. (One click is enough). We have some non-technical limitations and due this limitation we can't configure user's mail servers. But actually we have physical access to their laptops. As far as I know, there is possible to mount user's home directory without "x" (execution) permission in Linux and *BSD. So users can't run some binary file inside home directory. Is it possible to configure OS X so that user can't execute files inside /Users/?

  • Pull/push student assignment files from computer lab computers (Windows 7)

    - by mkstreet
    I have a computer lab with about 35 PC's all running Windows 7. The students do their work and save it on the D-drive in a particular folder such as a folder with the same name as the computer's name (e.g. LABPC001). I'd like a centralized way to pull all these folders in to the teacher's computer in the lab to check the assignments. It would be best if this didn't involve using an external website (e.g. Dropbox). I would also like to be able to distribute (send) files to the students in these same folders. I've seen software applications that do this but they cost about US$1000 which is far beyond our means. Suggestions for free, or almost free, best ways to set this up?

  • What is an effective way to familiarize yourself with a new application in a new language? [closed]

    - by codeninja
    Possible Duplicate: How do I pick up a new language quickly, given I know several others? I started a new job working on an application I'm vaguely familar with, and it's in PERL! I come from a PHP and Java background, so while I understand the basics, there are lot of nuances in PERL that make it troublesome. updated < Im supposed to be a UI developer, but the smallness of the office requires me to learn and do a lot more than just javascript. So that was slightly unexpected in some aspects and I'm just thinking about what approach to take with this /updated So far I've been sifting through the code to understand what each part does, printed out copies of code and try to lookup APIs I'm not familiar with, and so I dunno how effective this process is -- I feel like it's gonna take some time -- and I dont want my new employers to feel like I'm not being productive. Anyone have some ideas or approaches for this kind of situation? I read some of the questions about learning new languages, but I'm curious to see if anyone's had experience with this with PERL.

  • Run a service after networking is ready on Ubuntu?

    - by TK Kocheran
    I'm trying to start a service that depends on networking being started, whenever the computer is rebooted. I have a few questions: Is this easily possible from an /etc/init.d script? I have tried creating a script here (conforming to the standards), but I'm really doubtful that it's even running on boot, let alone working. When I test it manually, it works. I've seen the new Upstart service, but as far as how that actually works, I'm completely in the dark. How can I make a script that runs on boot which runs after networking has been started? If I could run it after connected to wireless network, even better :)

  • Named my RPi 512MB @jerpi_bilbo

    - by hinkmond
    To keep our multiple Raspberry Pi boards apart from each other, I've now named my RPi Model B w/512MB: "jerpi_bilbo", which stands for Java Embedded Raspberry Pi - Bilbo (named after the Hobbit from the J.R.R. Tolkien stories). I also, set up a Twitter account for him. You can follow him at: @jerpi_bilbo He's self-tweeting, manual prompted so far (using Java Embedded 7.0 and twitter4j Java library). Works great! I'm setting him up to be automated self-tweeting soon, so watch for that... Here's a pointer to the open source twitter4j Java library: download here Just unzip and extract out the twitter4j-core-2.2.6.jar and put it on your Java Embedded classpath. Here's how @jerpi_bilbo uses it to Tweet with his Java Embedded runtime: import twitter4j.*; import java.io.* public final class Tweet { public static void main(String[] args) { String statusStr = null; if ((args.length 0) && (args[0] != null)) { statusStr = args[0]; } else { statusStr = new String("Hello World!"); } // Create new instance of the Twitter class Twitter twitter = new TwitterFactory().getInstance(); try { Status status = twitter.updateStatus(statusStr); System.out.println ("Successfully updated the status to: " + status.getText()); } catch (Exception e) { e.printStackTrace(); } } } That's all you need. Java Embedded rocks the RPi! And, @jerpi_bilbo is alive... Hinkmond

  • How to choose NoSQL database engine?

    - by Poma
    We have a database with following specs: 30k records, 7mb in size 20 inserts/second 1000 updates/second 1000 range selects/second, by secondary index, approx 10 rows each needs at least one secondary index needs some mechanism to expire keys if they are not updated for 75 secs (can be done via programmatic garbage collector but will require additional 'last_update' index and will add some load) consistency is not required durability is not required db should be stored in memory For now we use Redis, but it does not have secondary index and it's keys index:foo:* is too slow. Membase also does not have secondary index (as far as I know). MongoDB and MySQL memory engine have table-level locks. What engine will fit our use case?

  • Android: Not able to experiment on own?

    - by user221287
    I have just started learning Android App Development a few days ago, with prior knowledge of C/C++, HTML and CSS. This is the situation I am facing Repeatedly: I am learning from a Video Tutorial Series, after each video, or each few videos, I say myself: Let's use what I have just learnt in the simple (and also "meaningless") app that I have made so far by watching the tutorials. I start implementing it, but then after a few minutes, I realize that I cannot do it because I do not know a few other syntax related to the particular thing, (or) I do not know whether these things can be combined with these other things by the use of . (dot). Whatever I try, I get either an error in eclipse or "Sorry...the app com.example.simple has stopped unexpectedly...." when the app runs. Then I search StackOverflow, Google and learn that what I want to implement requires learning about a few more classes, syntax and creating a few more java classes. I am not able to experiment on my own. Is it normal? Is it the HARD-WAY in which one is supposed to learn? Should I first learn Java and then come back to Android - would that be helpful?

  • btrfs and missing free space

    - by easteregg
    I converted my ext4 partition to btrfs and deleted the save subvolume after doing so. Then I enabled the compression (lzo) of the filessystem in the fstab file and everything is correct so far. Then I forced the compression of all files using the defragmentation command with the parameter -c that the new compression is applied to all files. While doing so, I noticed that my ssd got completly filled up - before I had 6gigs of free space. No I got nothing left. easteregg@x201s:~$ btrfs fi df / Data: total=50.00GB, used=49.17GB System: total=32.00MB, used=4.00KB Metadata: total=24.50GB, used=9.86GB and easteregg@x201s:~$ df -ha Filesystem Size Used Avail Use% Mounted on /dev/sda1 75G 60G 852M 99% / So now. How can I regain my free space. I expected to gain more space because of the lzo compression. And now! The fs is correctly mounted. easteregg@x201s:~$ mount /dev/sda1 on / type btrfs (rw,noatime,ssd,compress=lzo) Any ideas how to fix this issue?

  • Can mod_rewrite Conditions/Rules be executed in random order?

    - by Tom
    I have some mod rewrite rules that test for the presence of a file on various NFS mounts and I would like that the tests occur randomly, as a very rudimentary way to distribute load. For example: RewriteEngine on RewriteCond %{REQUEST_URI} ^/(.+)$ RewriteCond /mnt/mount1/%1 -f RewriteRule ^/(.+)$ /mnt/mount1/$1 [L] RewriteCond %{REQUEST_URI} ^/(.+)$ RewriteCond /mnt/mount2/%1 -f RewriteRule ^/(.+)$ /mount2/$1 [L] RewriteCond %{REQUEST_URI} ^/(.+)$ RewriteCond /mnt/mount3/%1 -f RewriteRule ^/(.+)$ /mnt/mount3/$1 [L] RewriteCond %{REQUEST_URI} ^/(.+)$ RewriteCond /mnt/mount4/%1 -f RewriteRule ^/(.+)$ /mnt/mount4/$1 [L] As far as I understand mod_rewrite Apache will look for the file on /mnt/mount1, then mount2, mount3 and so on. Can I randomize this on each request? I understand this is an odd request but I need a creative solution to some unforeseen downtime. On a side note, do I need to redeclare RewriteCond %{REQUEST_URI} ^/(.+)$ each time like I have done? Thanks

  • Is it preferable to use POP or IMAP to check multiple google mail accounts from one?

    - by Adam Tuttle
    I have email accounts on several domains that use Google Mail, and thus far I've only ever used POP to send and receive mail from a single inbox. This is quite functional, and as long as I remember to select the appropriate FROM address when starting a new thread, mostly works without any additional thought: messages received on account A are replied to via account A, and so on. My only complaint is the lag -- I've seen sometimes as much as a half hour between messages arriving in an inbox before being imported into my primary inbox via POP. My question is this: Google also supports IMAP. Would that be in any way preferable over POP access? Reduced lag would be nice, but not at a general speed cost, if everything I do has to check another mailbox too.

  • How can I get all my itunes files from multiple computers onto my new PC?

    - by jasondavis
    Managing my itunes files (music,video,tv shows, iphone apps) is a really hard task and I have not had much luck yet. If I had a single PC for the rest of my life with the same hard drive, it would work great but infortunately it cannot be that simple. I just build a new PC as my old hard drive crashed with all my itunes purchased songs, video, etc. So is there anyway to get itunes to recognize that I own all them and let me re-download everything? As I see it so far, it knows what I own by my itunes account login (it knows if I purchased a file or not ever) but does not seem to let you just re-download everything to a new PC or new hard drive. I realize I should of had backups but I didn't. My backup plan is a work in process and it is getting much better but that doesnt help with my situation at the moment. So I am asking for any help, ideas of how to retrieve all my previous itunes purchases?

  • Pros and Cons of Facebook's React vs. Web Components (Polymer)

    - by CletusW
    What are the main benefits of Facebook's React over the upcoming Web Components spec and vice versa (or perhaps a more apples-to-apples comparison would be to Google's Polymer library)? According to this JSConf EU talk and the React homepage, the main benefits of React are: Decoupling and increased cohesion using a component model Abstraction, Composition and Expressivity Virtual DOM & Synthetic events (which basically means they completely re-implemented the DOM and its event system) Enables modern HTML5 event stuff on IE 8 Server-side rendering Testability Bindings to SVG, VML, and <canvas> Almost everything mentioned is being integrated into browsers natively through Web Components except this virtual DOM concept (obviously). I can see how the virtual DOM and synthetic events can be beneficial today to support old browsers, but isn't throwing away a huge chunk of native browser code kind of like shooting yourself in the foot in the long term? As far as modern browsers are concerned, isn't that a lot of unnecessary overhead/reinventing of the wheel? Here are some things I think React is missing that Web Components will care of. Correct me if I'm wrong. Native browser support (read "guaranteed to be faster") Write script in a scripting language, write styles in a styling language, write markup in a markup language. Style encapsulation using Shadow DOM React instead has this, which requires writing CSS in JavaScript. Not pretty. Two-way binding

  • What service or software should I use to serve advertising on a site with about 120k monthly page views?

    - by JasonBirch
    I have a site that is generating about 120k monthly page views and is being hosted on a shared FreeBSD server where I have access to PHP and MySQL. I am using some custom PHP server-side scripts that give each of my ad networks (AdSense, Tribal Fusion, etc) an adjustable percentage of impressions in each of the ad positions on my pages. I am looking for a better way of managing and measuring the delivery of these ads, and would also like to be able to take direct placements and provide statistics to the clients. I am looking at options including OpenX self-hosted, OpenX community, and Google DoubleClick for Publishers Small Business (DFP), but am having difficulty determining which one will best meet my needs. They all seem to have pretty steep learning curves compared to my simple scripts. What I have taken away so far as the benefit of self-hosting is that I don't have to pay for the service if I exceed a maximum number of ad impressions, while both OpenX Community and DFP have free impression limits. Of course, if I was doing those kind of numbers I'd need to upgrade my hosting account, but I'm not sure even at that point whether it would be cheaper to serve the ads myself than pay for a premium service. Apart from this, I really need insights into what features differentiate these services, why I might want to choose one over another, and if there are any other competing products or service of the same quality that I should look into. Answers from webmasters who have used both (or all three) services and can talk to usability and ease of ad management would be highly appreciated.

What is the best way to go about this?

  • Kernel compiling with -j2+ parameter ends prematurely with no error message or output bzImage

    - by Minix
    I've noticed quite a while ago that compiling a kernel with the parameter -j set to 1 or more doesn't produce a bzImage. Instead, it ends prematurely without any advice. I have reproduced the same behavior in both my netbook and home server. As far as I'm aware, the point where the compilation stops is random - Compiling twice with the same parameters will probably stop at different files. However, when I run make with no -j* parameter the compilation ends just fine and outputs a working bzImage. Both machines run Intel Atom (N270 on the netbook and 330 on the server) and I've compiled for these processors. If I recall correctly, I've tried compiling both with Atom and with generic x86_64 options. The kernel version I'm building is 2.6.34.1 I've always compiled normally with those options in my Core2Duo and Pentium Dual Core machines. Has anyone experienced this issue? Any ideas why does this happens? Is there a fix or workaround?

  • Ubuntu 11.10 very slow compared to Windows

    - by Patrick
    I'm new to Ubuntu/linux. Since my PC is very old and not very fast with Windows 7, I decided to give Ubuntu a try, so I downloaded and installed Ubuntu 11.10 today. When I first started it, I had bad 800x600 resolution and it was very slow and annoying. So I installed a driver for my graphic card and now everything looks very nice (1280x1024).But I think it's still far slower than Windows 7. I tried to run in Ubuntu like a few people suggested on the forum but if I log in I get a black screen saying something like "this video mode cannot be displayed". I get that same screen when booting Ubuntu btw, but after about 15 seconds it disappears and just starts Ubuntu. I also installed other drivers for my graphic card but everything stayed the same. I noticed that i.e. when I open Firefox or system settings it takes about 5 seconds till it opens (while Windows 7 takes under 1 second to start i.e. Chrome) and when I do this my CPU usage gets to 100% for a short time. Computer specs: Memory: 2GB RAM Processor: Intel Pentium 4 2.8GHz Graphics Card: Nvidia GeForce 6800 400MHz. I read on various forums that 11.04 works flawless on many PCs, where 11.10 is very slow. Should I install 11.04 or could anybody help me with this problem?

  • How to match responses from a server with their corresponding requests? [closed]

    - by Deele
    There is a server that responds to requests on a socket. The client has functions to emit requests and functions to handle responses from the server. The problem is that the request sending function and the response handling function are two unrelated functions. Given a server response X, how can I know whether it's a response to request X or some other request Y? I would like to make a construct that would ensure that response X is definitely the answer to request X and also to make a function requestX() that returns response X and not some other response Y. This question is mostly about the general programming approach and not about any specific language construct. Preferably, though, the answer would involve Ruby, TCP sockets, and PHP. My code so far: require 'socket' class TheConnection def initialize(config) @config = config end def send(s) toConsole("--> #{s}") @conn.send "#{s}\n", 0 end def connect() # Connect to the server begin @conn = TCPSocket.open(@config['server'], @config['port']) rescue Interrupt rescue Exception => detail toConsole('Exception: ' + detail.message()) print detail.backtrace.join('\n') retry end end def getSpecificAnswer(input) send "GET #{input}" end def handle_server_input(s) case s.strip when /^Hello. (.*)$/i toConsole "[ Server says hello ]" send "Hello to you too! #{$1}" else toConsole(s) end end def main_loop() while true ready = select([@conn, $stdin], nil, nil, nil) next if !ready for s in ready[0] if s == $stdin then return if $stdin.eof s = $stdin.gets send s elsif s == @conn then return if @conn.eof s = @conn.gets handle_server_input(s) end end end end def toConsole(msg) t = Time.new puts t.strftime("[%H:%M:%S]") + ' ' + msg end end @config = Hash[ 'server'=>'test.server.com', 'port'=>'2020' ] $conn = TheConnection.new(@config) $conn.connect() $conn.getSpecificAnswer('itemsX') begin $conn.main_loop() rescue Interrupt rescue Exception => detail $conn.toConsole('Exception: ' + detail.message()) print detail.backtrace.join('\n') retry end

  • Nginx HTTPS when only matching admin subfolder

    - by sebastyuiop

It feels like I need to put something in the empty block. server { listen 443; location /admin { } location / { rewrite ^ http://$server_name$request_uri?$args permanent; } } Thanks
