  • I studied electrical engineering. Can I work as a developer? [closed]

    - by FailedDev
    A while ago I finished my Msc in Electrical Engineering and started working as an engineering consultant where I mostly do development work. I am good at picking up languages/technologies tools. I have fiddled with C/C++/C#/perl/ant/bash/html/css etc. Although I have never had a complain for my work, rather the contrary, I just feel that some day, someone will ask me a real hard task which would maybe seem rather trivial for a computer scientist but hard for me. Should I read/do something to become a better developer. Should I pick up a book about design patterns or algorithms for example? Is this normal that I have this kind of "fear"? Sorry if this is the wrong place to post this question. Please notify me so I can close it if this is the case.

  • EM CLI, diving in and beyond!

    - by Maureen Byrne
    v\:* {behavior:url(#default#VML);} o\:* {behavior:url(#default#VML);} w\:* {behavior:url(#default#VML);} .shape {behavior:url(#default#VML);} Doing more in less time… Isn’t that what we all strive to do? With this in mind, I put together two screen watches on Oracle Enterprise Manager 12c command line interface, or EM CLI as it is also known. There is a wealth of information on any topic that you choose to read about, from manual pages to coding documents…might I even say blog posts? In our busy lives it is so nice to just sit back with a short video, watch and learn enough to dive in. Doing more in less time, is the essence of EM CLI. It enables you to script fundamental and complex administrative tasks in an elegant way, thanks to the Jython scripting language. Repetitive tasks can be scripted and reused again and again. Sure, a Graphical User Interface provides a more intuitive step by step approach to tasks, and it provides a way of quickly becoming familiar with a product and its many features, and it is definitely the way to go when viewing performance data and historical trending…but for repetitive and complex tasks, scripting is the way to go! Lets us take the everyday task of creating an administrator. Using EM CLI in interactive mode the command could look like this.. emcli>create_user(name='jan.doe', type='EXTERNAL_USER') This command creates an administrator called jan.doe which is an externally authenticated user, possibly LDAP or SSO, defined by the EXTERNAL_USER tag. The create_user procedure takes many arguments; see the documentation for more information. Now, where EM CLI really shines and shows power is in creating multiple users. Regardless of the number, tens or thousands, the effort is the same. With the use of a standard programming construct, a loop, you can place your create_user() procedure within it. Using a loop allows you to iterate through a previously created list, creating new users until the list is complete. Using EM CLI in Script mode, your Jython loop would look something like this… for user in list_of_users:       create_user(name=user, expire=’true’, password=’welcome123’) This Jython code snippet iterates through a previously defined list of names, list_of_users, and iterates through the list, taking each name, user in this case, and creates an administrator sets the password to welcome123, but forces the user to reset it when they first login. This is only one of over four hundred procedures created to expose Oracle Enterprise Manager 12c functionality in a powerful and programmatic way. It is a few months since we released EM CLI with scripting option. We are seeing many users adapt to this fun and powerful way of using Oracle Enterprise Manager 12c. What are the first steps? Watch these screen watches, and dive in. The first screen watch steps you through where and how to download and install and how to run your first few commands. The Second screen watch steps you through a few scripts. Next time, I am going to show you the basic building blocks to writing a Jython script to perform Oracle Enterprise Manager 12c administrative tasks. Join this growing group of EM CLI users…. Dive in!

  • Ubuntu boots to black screen after failed upgrade from 12.04 to 12.10

    - by ywx
    This happened when I tried to upgrade from 12.04 to 12.10. I don't know whether the upgrade process had completed downloading and installing packages or whether it was still in progress, but I got a message The application Compiz has closed unexpectedly. At that point, my mouse stopped working so I switched to tty1 by Ctrl+Alt+F1 and rebooted from there. I then found that I could not boot into Ubuntu any more. My screen stayed first purple then black. I went back to tty1 and it said I was running 12.10. I tried some suggestions in this thread on Ubuntuforums: Wubi blank purple screen than blank black screen and this one: How to set NOMODESET and other kernel boot options in grub2 but nothing seemed to work. I can boot Windows as normal. I am using Wubi on Windows7. My laptop is a Lenovo T410i with NVIDA NVS 3100m

  • Scrambled screen on 12.04 with Radeon HD 7670M/2GB when scrolling the page

    - by Mihkel
    I have Ubuntu 12.04 LTS 64 bit and I have installed proprietary drivers for my Radeon HD 7670M with 2GB memory. But if I scroll page or do anything like move a window then I get blurred screen (more like scrambled maybe) for a second and if I try to take PrtScr of it, it is goes to normal. I have tried other drivers and it does not solve my problem. And I do not want to go over 32 bit Ubuntu because I have 6 GB ram and I would lose so much of it. Also if it helps, my processor is Intel® Core™ i5-3210M CPU @ 2.50GHz × 4.

  • Redirecting non existing post to homepage; is that good for SEO?

    - by BlackEagle
    I am checking my website out on Google Webmasters and I am seeing an astonishing 5000 links that could not be found by Google's Crawlers. That's normal, because my website is built in a manner that users can drop their own things, which also lead to 404 pages. Not a problem at all if I can find a workaround of course... So my question is: what if I made a function or a mod rewrite that will check if the link exists (a post for example) and if not, it will redirect it to the home page. Is this good for SEO? Will Google see this as 'link found'? How do I have to look at this problem?

  • Sanity checks vs file sizes

    - by Richard Fabian
    In your game assets do you make room for explicit sanity checks, or do you have some generally expected bounds which you assert? I've been thinking about how we compress data and thought that it's much better to have the former, and less of the latter. If your data can exceed your normal valid ranges, but if it does it's an error, then surely that implies you're not compressing the data well enough? What do you do to find out if your data is compressed as far as it can be, and what do you use to ensure your data isn't corrupted and ensure it's an official release? EDIT I'm not interested in sanity checking the file size, but instead, how you manage your sanity checks and whether you arrange the excess size caused by the opportunity to do sanity checks by using explicit extra data, or through allowing the data enough file space (data member size) to be out of valid range and thus able to be checked merely by looking at the asset in memory after loading.

  • Why does pasting sometimes not work in gnome-terminal?

    - by Matthew
    Ctrl + Shift + C and Ctrl + Shift + V are supposed to replace the normal Ctrl + C and Ctrl + V in gnome-terminal. Sometimes they work, but usually they have no effect. What are some potential reasons for this? I'm not sure what other information to give. Edit: It seems that manually selecting Paste from the Edit menu does not work either. Right click > Paste works, but Edit > Paste does not. Copying works, but pasting does not. Also, I have vi-mode enabled (set -o vi in my ~/.bashrc). Could this have something to do with it? Edit: Here is a video demonstrating the problem. I used Screenkey (in "raw" mode, to catch "shift") to show what keys I am pressing.

  • Is scanning the ports considered harmful?

    - by Manoj R
    If any application is scanning the ports of other machines, to find out whether any particular service/application is running, will it be considered harmful? Is this treated as hacking? How else can one find out on which port the desired application is running (without the user input)? Let's say I only know the port range in which the other application could be running, but not the exact port. In this case, my application ping each of the port in range to check whether the other application is listening on it, using already defined protocol. Is this a normal design? Or is this considered harmful for the security?

  • Secure Your Wireless Router: 8 Things You Can Do Right Now

    - by Chris Hoffman
    A security researcher recently discovered a backdoor in many D-Link routers, allowing anyone to access the router without knowing the username or password. This isn’t the first router security issue and won’t be the last. To protect yourself, you should ensure that your router is configured securely. This is about more than just enabling Wi-Fi encryption and not hosting an open Wi-Fi network. Disable Remote Access Routers offer a web interface, allowing you to configure them through a browser. The router runs a web server and makes this web page available when you’re on the router’s local network. However, most routers offer a “remote access” feature that allows you to access this web interface from anywhere in the world. Even if you set a username and password, if you have a D-Link router affected by this vulnerability, anyone would be able to log in without any credentials. If you have remote access disabled, you’d be safe from people remotely accessing your router and tampering with it. To do this, open your router’s web interface and look for the “Remote Access,” “Remote Administration,” or “Remote Management” feature. Ensure it’s disabled — it should be disabled by default on most routers, but it’s good to check. Update the Firmware Like our operating systems, web browsers, and every other piece of software we use, router software isn’t perfect. The router’s firmware — essentially the software running on the router — may have security flaws. Router manufacturers may release firmware updates that fix such security holes, although they quickly discontinue support for most routers and move on to the next models. Unfortunately, most routers don’t have an auto-update feature like Windows and our web browsers do — you have to check your router manufacturer’s website for a firmware update and install it manually via the router’s web interface. Check to be sure your router has the latest available firmware installed. Change Default Login Credentials Many routers have default login credentials that are fairly obvious, such as the password “admin”. If someone gained access to your router’s web interface through some sort of vulnerability or just by logging onto your Wi-Fi network, it would be easy to log in and tamper with the router’s settings. To avoid this, change the router’s password to a non-default password that an attacker couldn’t easily guess. Some routers even allow you to change the username you use to log into your router. Lock Down Wi-Fi Access If someone gains access to your Wi-Fi network, they could attempt to tamper with your router — or just do other bad things like snoop on your local file shares or use your connection to downloaded copyrighted content and get you in trouble. Running an open Wi-Fi network can be dangerous. To prevent this, ensure your router’s Wi-Fi is secure. This is pretty simple: Set it to use WPA2 encryption and use a reasonably secure passphrase. Don’t use the weaker WEP encryption or set an obvious passphrase like “password”. Disable UPnP A variety of UPnP flaws have been found in consumer routers. Tens of millions of consumer routers respond to UPnP requests from the Internet, allowing attackers on the Internet to remotely configure your router. Flash applets in your browser could use UPnP to open ports, making your computer more vulnerable. UPnP is fairly insecure for a variety of reasons. To avoid UPnP-based problems, disable UPnP on your router via its web interface. If you use software that needs ports forwarded — such as a BitTorrent client, game server, or communications program — you’ll have to forward ports on your router without relying on UPnP. Log Out of the Router’s Web Interface When You’re Done Configuring It Cross site scripting (XSS) flaws have been found in some routers. A router with such an XSS flaw could be controlled by a malicious web page, allowing the web page to configure settings while you’re logged in. If your router is using its default username and password, it would be easy for the malicious web page to gain access. Even if you changed your router’s password, it would be theoretically possible for a website to use your logged-in session to access your router and modify its settings. To prevent this, just log out of your router when you’re done configuring it — if you can’t do that, you may want to clear your browser cookies. This isn’t something to be too paranoid about, but logging out of your router when you’re done using it is a quick and easy thing to do. Change the Router’s Local IP Address If you’re really paranoid, you may be able to change your router’s local IP address. For example, if its default address is 192.168.0.1, you could change it to 192.168.0.150. If the router itself were vulnerable and some sort of malicious script in your web browser attempted to exploit a cross site scripting vulnerability, accessing known-vulnerable routers at their local IP address and tampering with them, the attack would fail. This step isn’t completely necessary, especially since it wouldn’t protect against local attackers — if someone were on your network or software was running on your PC, they’d be able to determine your router’s IP address and connect to it. Install Third-Party Firmwares If you’re really worried about security, you could also install a third-party firmware such as DD-WRT or OpenWRT. You won’t find obscure back doors added by the router’s manufacturer in these alternative firmwares. Consumer routers are shaping up to be a perfect storm of security problems — they’re not automatically updated with new security patches, they’re connected directly to the Internet, manufacturers quickly stop supporting them, and many consumer routers seem to be full of bad code that leads to UPnP exploits and easy-to-exploit backdoors. It’s smart to take some basic precautions. Image Credit: Nuscreen on Flickr

  • How to adjust TouchPad edge scroll area in Ubuntu?

    - by MikeVB
    I have an Acer Aspire that I have dual booting XP and Ubuntu. On the Windows side, the driver allows you to set how close your finger has to be to the edge of the TouchPad before it goes into scroll mode. In Ubuntu I don't have the option (at least in the GUI) to change the scroll area on the pad. Is there a conf file or other way to change this? I'm constantly getting into the scroll area during normal usage. I would like to leave it on without losing so much pad area to the scroll feature.

  • window borders, menu bar missing over VNC

    - by zacaj
    I'm running Ubuntu 14.04 with Unity and Gnome3, however I don't have a screen hooked up anymore. I have installed x11vnc and run it with "-create" so that it will create a new X11 session, however when I VNC to it, the menu bar, window borders, etc are missing, windows are ordered based on creation time, and cannot be resized. Now, I don't really care if I end up with Ubuntu or Gnome's window manager, as long as this doesn't mess up my normal desktop stuff if I should happen to hook a monitor up again, and I'm not even attached to x11vnc if someone can point me to a good complete tutorial using something else, but I've been trying vino and tightvnc and rdp and x11vnc is the only one I've managed to get this far.

  • Bouncing ball slowing down over time

    - by user46610
    I use the unreal engine 4 to bounce a ball off of walls in a 2D space, but over time the ball gets slower and slower. Movement happens in the tick function of the ball FVector location = GetActorLocation(); location.X += this->Velocity.X * DeltaSeconds; location.Y += this->Velocity.Y * DeltaSeconds; SetActorLocation(location, true); When a wall gets hit I get a Hit Event with the normal of the collision. This is how I calculate the new velocity of the ball: FVector2D V = this->Velocity; FVector2D N = FVector2D(HitNormal.X, HitNormal.Y); FVector2D newVelocity = -2 * (V.X * N.X + V.Y * N.Y) * N + V; this->Velocity = newVelocity; Over time, the more the ball bounced around, the velocity gets smaller and smaller. How do I prevent speed loss when bouncing off walls like that? It's supposed to be a perfect bounce without friction or anything.

  • Instruct Ubuntu to boot TORAM from flash drive using unetbootin

    - by Goyuix
    I have used UNetbootin to create an installable / live bootable flash drive from Ubuntu 12.04. However that didn't preserve the normal Ubuntu boot menu which allows to me to enter advanced options. It has a custom menu that I can pick from predefined choices like "Install Ubuntu" and "Try Ubuntu without installing". What I would like is to be able to boot from the USB flash drive, but then be able to remove it from the computer once the desktop has loaded. The laptop I would like to use this on does not have a CD/DVD drive. What do I need to modify on the flash drive to add an option to "Try Ubuntu (RAM)" that passes the TORAM=yes parameter to the initrd options? Are their other things I need to touch/change as well? Bonus: I would guess the answer would also allow for other options like acpi=off as well, but if it is different I would appreciate having that answer too.

  • What is the best way to become a professional in PHP and Website Building?

    - by Mr.TAMER
    I would like to become a professional in php, I have learned nearly all about the language syntax and concepts and I have a good knowledge in C and C++, which made it easier to become familiar with PHP. (Of course, I learned MySql too.) But I don't feel like being able to build even a little good website of my own! It looks like PHP is all about knowing lots of functions and using them, while in fact I don't think it's like that, is it? How can I become a professional in PHP and Website Building? I would do anything and spend whatever amount of time required for that. EDIT I've also a very good knowledge in HTML and a normal knowledge in CSS and JavaScript. Sorry for not mentioning that, I just thought it was implicitly included.

  • One of my user accounts logs in without desktop environment

    - by Bill Cheatham
    When I log in to my main user account on Ubuntu 11.10 ,the desktop environment (unity bar, clock, volume control, etc.) is not there. All I have is the desktop background with a menu bar across the top which appears to be for nautilus (options like File-New folder). My other accounts log in like normal. I have recently followed these instructions to give my main user account access to an OSX partition, but I think I have logged in successfully since then. I am able to get a terminal by pressing ctrl+alt+t, but when I typed unity the whole thing crashed. Is there anything I can do to fix this? I have a separate administrator account I can use if needed.

  • Inkscape won't open .cdr files

    - by Bora George
    Hello I'm running Kubuntu 12.04 and I've installed Inkscape because I need to edit a .cdr file, Inkscape works like normal but the sole task I need it to do is edit said .cdr file which I understand it should be capable off by default. Whenever I try to open the file though I get the following error: UniConvertor failed: The eror itself is longer but what it seems to be saying that it can't find this application, and I myself haven't found it in the package manager. If someone has experienced something similar or has a simple solution for editing cdr's I'm no artist I just need to change some names, I would be very gratefull. The full error.

  • Problem with deleting table rows using ctrl+a for row selection

    - by Frank Nimphius
    Normal 0 false false false EN-US X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} The following code is commonly shown and documented for how to access the row key of selected table rows in an ADF Faces table configured for multi row selection. public void onRemoveSelectedTableRows(ActionEvent actionEvent) {    RichTable richTable = … get access to your table instance …    CollectionModel cm =(CollectionModel)richTable.getValue();    RowKeySet rowKeySet = (RowKeySet)richTable.getSelectedRowKeys();             for (Object key : rowKeySet) {       richTable.setRowKey(key);       JUCtrlHierNodeBinding rowData = (JUCtrlHierNodeBinding)cm.getRowData();       // do something with rowData e.g.update, print, copy   }    //optional, if you changed data, refresh the table         AdfFacesContext adfFacesContext = AdfFacesContext.getCurrentInstance(); adfFacesContext.addPartialTarget(richTable);   return null; } The code shown above works for 99.5 % of all use cases that deal with multi row selection enabled ADF Faces tables, except for when users use the ctrl+a key to mark all rows for delete. Just to make sure I am clear: if you use ctrl+a to mark rows to perform any other operation on them – like bulk updating all rows for a specific attribute – then this works with the code shown above. Even for bulk row delete, any other mean of row selection (shift+click and multiple ctrl+click) works like a charm and the rows are deleted. So apparently it is the use of ctrl+a that causes the problem when deleting multiple rows of an ADF Faces table. To implement code that works for all table selection use cases, including the one to delete all table rows in one go, you use the code shown below. public void onRemoveSelectedTableRows(ActionEvent actionEvent) {   RichTable richTable = … get access to your table instance …   CollectionModel cm = (CollectionModel)richTable.getValue();   RowKeySet rowKeySet = (RowKeySet)richTable.getSelectedRowKeys();   Object[] rowKeySetArray = rowKeySet.toArray();      for (Object key : rowKeySetArray){               richTable.setRowKey(key);     JUCtrlHierNodeBinding rowData = (JUCtrlHierNodeBinding)cm.getRowData();                              rowData.getRow().remove();   }   AdfFacesContext adfFacesContext = AdfFacesContext.getCurrentInstance();          adfFacesContext.addPartialTarget(richTable); }
