Some cool tricks for Linux
than your GUI started up in.
Ctrl+Alt+'-': Using this command switched the screen resolution lower.
Ctrl+Alt+Backspace': It kills the X server. Use it if your normal
logout option does not work.
Shift+PageUp: Scrolls up through the terminal output. Use this and the
one below to move through screenfuls of information.
Shift+PageDown: Scrolls down through the terminal output.
Ctrl+Alt+F1: Linux gives you the capability of working on more than
one virtual terminal at a time. You can have any number of virtual
terminals but most Linux system are setup for six that are accessible
through 'ctrl + alt + f1' to 'ctrl + alt + f6'. So, basically f1-fn
tells your system to switch to the virtual terminal corresponding to
the function key number. You will be using this most often to jump
from one terminal to another.
Ctrl+Alt+F7: While working in the Unix command line interface, if you
want to get back into the GUI mode, all you have to do is issue this
command.
Ctrl+C: This command halts a running process. Use this to quickly exit
from any program that you are running.
Ctrl+D: This command is used to log you out of a particular terminal.
It also issues an EOF (End Of File) to the program that you are
working in.
Ctrl+Z: Sends a current process into the background. Also if your
terminal is messed up because you 'cat' a binary file 'ctrl + z' will
clear up the screen for you and give you a clean prompt.
Ctrl+S: Scroll lock. Your screen will not be updated.
Ctrl+Q: Remove the scroll lock set above. You will now be able to
interact properly with your terminal.
Tab: One of the most used keys. Pressing the 'tab' key while typing
the path to any directory or a filename is very helpful. Write the
first few characters of the file or directory and press the tab key to
complete the name or give you a list of possibilities. When pressed
during an incomplete command, the 'tab' key completes the command for
you.
Ctrl+Alt+Del: When used at the console it reboots the machine.
Remember it causes a soft boot and not a cold boot. The system will
shutdown all services before rebooting.
UP Arrow: In the terminal, it cycles through the list of commands that
you have executed.
GPM: Let's look at copying data from one virtual terminal to another.
This requires your mouse to be setup for GPM. Use mouseconfig under
Red Hat and Yast under SuSE to set up your mouse correctly. Also make
sure the package GPM is installed beforehand.
MiddleMouseButton: Just select the text you would want to copy using
your mouse. Do as you would under Windows. Press and hold the right
mouse button and then drag to select the text. Then switch to the
terminal you want to copy to and click the middle mouse button. This
will paste the text at the current cursor location.
~: This represents your home directory. Use this in a command and the
`~` will get replaced by your home directory. cd ~/freeos . This
command gets you to the 'freeos' directory, which is a sub-directory
under your home directory.
Setting the speed of your mouse in X: Do a "man xset" and look at the
option 'm'.
'Very Fast' xset m 7 10
'Normal(Fast)" xset m 3 10
"System Default" xset m default
"Glacial" xset m 0 10
The xset -m option takes two parameters: the first is the speed and
the second is the threshold value. But these values will be reset as
soon as you log out. To make this setting permanent, just add it to
the ".xsession" file in your home directory.
Ctrl+Right-Mouse-button: Setting your Font Size in xterm. To set your
font size in an Xterm you can make use of the command 'setfont' or
simply just do the following. If you are in an xterm use 'ctrl + right
mouse button. This will popup a menu where you can choose some
(standard) font-sizes.
How to kill Netscape but have it save your bookmarks and history:
'kill -12" (USR2) is more gracious, when used to terminate Netscape.
Netscape will save the bookmarks and history files of the current
session.
Disable Blanking in Text consoles:
setterm -blank 0. To make this setting permanent, just add it to
your .xsession file in your home directory.
To disable X-Server screen blanking:
xset s off
To make this setting permanent, just add it to your .xsession file in
your home directory.
Turning off PING reply:
PING ( Packet Internet Groper ) is a service used most commonly to
figure out the network status of your machine. Many a time the useful
service provided by it could be used for a D.O.S. (Denial Of Service)
attack against you.
A simple 'echo 1 > /proc/sys/net/ipv4/icmp_echo_ignore_all' will do
the trick. To turn it back on, simply 'echo 0 > /proc/sys/net/ipv4/
icmp_echo_ignore_all' to turn off the service.
Killing a Virtual Console without rebooting:
Log in as root, type 'lsof /dev/ttyx' where the 'x' in /dev/ttyx is
the terminal number of the hung virtual console. This will show you
the process that occupies this tty. Kill it and the getty process for
that virtual console should respawn.
32 Cool Tips for Windows XP
2. Press Win+L to lock your workstation.
3. You can switch users without going through the Welcome screen:
From Task Manager, go to the Users tab, right-click a user, and select
Connect.
4. Hold down the shift key in the shutdown dialog to change "Stand By"
to "Hibernate". Or just press H to hibernate instantly. You can even
use the Power Control Panel to configure your power button to
hibernate.
5. To disable the password when resuming from standby or hibernation,
open the Power Control Panel and uncheck "Prompt for password after
returning from standby" on the Advanced tab.
6. You can rename multiple files all at once: Select a group of files,
right-click the first file, and select "Rename". Type in a name for
the first file, and the rest will follow.
7. Hold down the shift key when switching to thumbnail view to hide
the file names. Do it again to bring them back.
8. When dragging a file in Explorer, you can control the operation
that will be performed when you release the mouse button:
- Hold the Control key to force a Copy.
- Hold the Shift key to force a Move.
- Hold the Alt key to force a Create Shortcut.
9. If you create a file called Folder.jpg, that image will be used as
the thumbnail for the folder. What's more, that image will also be
used as the album art in Windows Media Player for all media files in
that folder.
10. From the View Menu, select "Choose Details" to select which file
properties should be shown in the Explorer window. To sort by a file
property, check its name in the "Choose Details" in order to make that
property available in the "Arrange Icons by" menu.
11. To display the volume control icon in the taskbar, go to the
Sounds and Audio Devices Control Panel and select "Place volume icon
in the taskbar".
12. Hold down the shift key when deleting a file to delete it
immediately instead of placing it in the Recycle Bin. Files deleted in
this way cannot be restored.
13. If you hold down the shift key while clicking "No" in a Confirm
File Operation dialog, the response will be interpreted as "No to
All".
14. To save a document with an extension other than the one a program
wants to use, enclose the entire name in quotation marks.
For example, if you run Notepad and save a file under the name
Dr.Z
it will actually be saved under the name Dr.Z.txt. But if you type
"Dr.Z"
then the document will be saved under the name Dr.Z. Note that a
document so-named cannot be opened via double-clicking since the
extension is no longer ".txt".
15. Put a shortcut to your favorite editor in your Send To folder and
it will appear in your "Send To" menu. You can then right-click any
file and send it to your editor.
16. Ctrl+Shift+Escape will launch Task Manager. 17. To arrange two
windows side-by-side, switch to the first window, then hold the
Control key while right-clicking the taskbar button of the second
window. Select "Tile Vertically".
18. To close several windows at once, hold down the Control key while
clicking on the taskbar buttons of each window. Once you have selected
all the windows you want to close, right-click the last button you
selected and pick "Close Group".
19. You can turn a folder into a desktop toolbar by dragging the icon
of the desired folder to the edge of the screen. You can then turn it
into a floating toolbar by dragging it from the edge of the screen
into the middle of the screen. (It helps if you minimize all
application windows first.)
20. You can turn a folder into a taskbar toolbar.
- First, unlock your taskbar.
- Next, drag the icon of the desired folder to the space between
the taskbar buttons and the clock. (Wait for the no-entry cursor to
change to an arrow. It's a very tiny space; you will have to hunt for
it.)
- You can rearrange and resize the taskbar toolbar you just
created.
- You can even turn the taskbar toolbar into a menu by resizing it
until only its name is visible.
21. In the Address Bar, type "microsoft" and hit Ctrl+Enter. Internet
Explorer automatically inserts the "http://www." and ".com" for you.
22. To remove an AutoComplete entry from a Web form, highlight the
item in the AutoComplete dropdown and press the Delete key. To remove
all Web form AutoComplete entries, go to the Internet Explorer Tools
menu, select Internet Options, Content, AutoComplete, then press the
"Clear Forms" button.
23. To organize your Favorites in Explorer instead of using the
Organize Favorites dialog, hold the shift key while selecting

"The older I get, the more I believe that the only way to become a better programmer is by not programming. You have to come up for air, put down the compiler for a moment, and take stock of what you're really doing. Code is important, but it's a small part of the overall process."
"To truly become a better programmer, you have to to cultivate passion for everything else that goes on around the programming."
"The nature of these jobs is not just closing your door and doing coding, and it's easy to get that fact out. The greatest missing skill is somebody who's both good at understanding the engineering and who has good relationships with the hard-core engineers, and bridges that to working with the customers and the marketing and things like that."

Master the use of routines to:
- reduce complexity
- avoid duplicate code
- reduce the effect of changes
- hide sequences
- improve performance
- hide data structure
- hide global data
- promote code reuse
- plan for a family of programs
- improve readability
- improve portability
- isolat the use of nonstandard language functions
- isolate complex operations
"Aside from the invention of the computer, the routine is arguably the single greatest invention in computer science. It makes programs easier to read and understand. It makes them smaller (imagine how much larger your code would be if you had to repeat the code for every call to a routine instead of invoking the routine). And it makes them faster (imagine how hard it would be to make performance improvements in similar code used in a dozen places rather than making all the performance improvements in one routine). In large part, routines are what make modern programming possible."
Read more: Why You Should Use Routines, Routinely.
"Good programmers -- regardless of whatever language they happen to be working in -- understand the importance of crafting each routine with the utmost care. The routines in your code should be treated like tiny, highly polished diamonds, each one more exquisitely polished and finely cut than the last."

- Learn to estimate software projects precisely
"We tend to look at software estimates as successive hundred yard dashes instead of a long distance race. It allows a client to pick out just what they want built, while using their line item veto on tasks they don't want to do. But this assumes that you can break a software system down into features that have no interactions. A series of silos, though, isn't an accurate description of software. There's interactions between features, and rarely do you see estimates take that into account."
- Learn to see, when you are overengineering things
"The problem with patterns, best practices and idioms is the overuse of a single principle. Regardless what you are considering: overuse of DRY can lead to "fat" layers and classes, overuse of Separation Of Concerns to many fine grained units, overuse of modularization to jar, plugin or just governance hell. Common sense and the balance between concepts and idioms are the solution- but it's hard to find in real world :-)."

- Test your app performance in conditions, similar to the live environment
"Your application is useful and popular. Your users love it. Your users love you. But over the next week, something curious happens. As people use the application, it gets progressively slower and slower. Soon, the complaints start filtering in. Within a few weeks, the app is well-neigh unusable due to all the insufferable delays it subjects users to-- and your users turn on you."

Find out the signs you are a bad programmer, symptoms and remedies to them:
- Inability to reason about code
- Poor understanding of the language's programming model
- Deficient research skills / Chronically poor knowledge of the platform's features
- Inability to comprehend pointers
- Difficulty seeing through recursion
Also the article covers signs that you are a mediocre programmer and that you shouldn't be a programmer.
Read more: Signs that you are a bad programmer (Bad Programmers)
- Choose your platform wisely.
"When we build our applications, we have to decide what foundation (or platform) to use, and those decisions are not at all simple. In fact, these technology choices can be so difficult that you don't have to be "foolish" to earn bad results. Many a wise man has watched his software product floating away in the floodwaters after a big rain."

Learn a framework, because
There are several reasons to work with a framework for a business:
- better application security
- improved time to market
- easier to find someone, who knows the framework
There are 3 reasons why developers benefit from frameworks, too:
- community support
- frameworks give you tools to do more work and earn more money
- it is easier to get a job, if you know any framework
Read more: should you learn a framework? Yes!
- There isn't one language that can solve all problems

- Learn about modelling.
"Modeling is frequently used in certain software development domains to help verify the design of software, both formally and informally, before implementation starts.
One of the reasons that this approach hasn't caught on in the programming community at large is that it slows down development and increases the overall cost significantly. You have to maintain separate artifacts that contain largely the same information: the source code and the model. Finally models are often ignored after implementation starts.
This is well-known in the modelling community as the Achilles heal of modeling. Nonetheless modeling is still important enough for creating correct and robust software that it is widely used in many software projects where robustness is important."

Learn to ask why
If a non-developer gives you a technical task for you to programm, ask "Why?". It might happen that the result that the client/manager wants to get can be achieved with much less effort.
Trying to understand how things work and asking people for more information definitely helps, too. (Thanks to Wade Wilson via DZone for the tip.)

Code as if comments don't exist
"While comments are neither inherently good or bad, they are frequently used as a crutch. You should always write your code as if comments didn't exist. This forces you to write your code in the simplest, plainest, most self-documenting way you can humanly come up with."
"When you've rewritten, refactored, and rearchitected your code a dozen times to make it easy for your fellow developers to read and understand -- when you can't possibly imagine any conceivable way your code could be changed to become more straightforward and obvious -- then, and only then, should you feel compelled to add a comment explaining what your code does."

- Don't Comment Your Code (an example of understandable code)
- Remember the rules of good commenting:
- The value of a comment is directly proportional to the distance between the comment and the code.
- Comments with complex formatting cannot be trusted.
- Don't include redundant information in the comments.
- The best kind of comments are the ones you don't need.
"The only "comments" guaranteed to be accurate 100% of the time-- and even that is debatable-- is the body of the code itself. Endeavor to write self-documenting code whenever possible."
Read more: Coding Horror: When Good Comments Go Bad
- Cope with the excuses to document everything:
- The code is not readable without comments
- We want to keep track of who changed what and when it was changed
- I wanted to keep a commented-out section of code there in case I need it again
- The code too complex to understand without comments
- Markers to easily find sections of code
- Natural language is easier to read than code

- Include business logic in your comments
"I often find that code I'm maintaining is missing comments regarding the business logic. Rather than "Why is the code designed like this?", something like "Why is the business process designed like this?"
This becomes most useful when you look at unfamiliar code (your own, probably) and decide that the easily-digestible code is nevertheless doing something you are sure is silly, and you change it. Big mistake."

- Master your soft skills to be a better person:
- Humanity
- Temperament
- Speech
"I have found that programmers who are willing to crack this social code with their soft skills, are often the very same geeks who end up in leadership positions, or who start their own company. I can say without question that it is not my ability to decipher collaborative filtering algorithms that has brought me the most success, but it is the soft skills that continue to generate interest with employers. This was a difficult realization, but one that I have come to accept and embrace."

- Create a list of things you need to do
"This software developer does not have a detailed list of all the things he needs to do. Which means, despite adamantly claiming that he is 99 percent done -- he has no idea how long development will take! There's simply no factual basis for any of his schedule claims."

- Not only be smart, but be willing to learn to become a good developer.
"The huge demand for developers, coupled with the relative youth of our industry, has created hordes of developers who simply don't understand what they are doing. They do not understand how computers work, or how a compiler works. They use dictionaries and stacks all the time, but they don't understand that these are classic data structures, and not something that Microsoft just made up. And the problem isn't that they don't know these things, it is that they don't want to know these things."

- Get a great, comfortable chair.
"In fact, after browsing chairs for the last few years of my career, I've come to one conclusion: you can't expect to get a decent chair for less than $500. If you are spending less than that on seating -- unless you are getting the deal of the century on dot-bomb bankruptcy auctions -- you're probably making a mistake."
"Choice of seating is as fundamental and constant as it gets in a programming career otherwise marked by relentless change. They are long term investments. Why not take the same care and consideration in selecting a chair as you would with the other strategic directions that you'll carry with you for the rest of your career? Skimping yourself on a chair just doesn't make sense. "

- Address negative attitudes in your team
"To Mr./Ms. Pessimism new ideas and new thinking are "yet another thing I have to learn", rather than a chance to improve one's self and challenge one's own assumptions. If left unchecked, such negative attitudes can result in the team member sticking their head in the sand in hopes they can avoid learning anything at all."

Scale your services to provide a better service to your clients, which they will appreciate. It'll come at a cost, but it's worth it.
"In the long run, what do great clients need? Do they need simple implementers that can get menial tasks done quickly and cheaply, or do they need long term, stable and reliable web development experts that can get the job, however great or small, done right the first time? Well, there are plenty of clients out there of either kind, but we aim to serve the latter group."

"To me, one of the most important parts of a job is the fact that you should enjoy doing it. If you do the math, you’ll quickly realize that you’ll spend somewhere around half of your active adult life at your job, so you might as well try to make the most of it. If you’re unhappy or frustrated at your job, you’re essentially wasting a large part of your life so you’re better off trying to find something that you actually enjoy doing."

Know available salary data, but don't worry about it.
Since you have your own unique set of abilities and skills and the company you want to work for has its situation, you'll be able to get a fairer salary, than, if you had one in mind.
Nick Corcodilos, the IT hiring expert and the owner of AskTheHeadHunter, advises IT jobseekers:
"You should never, ever, ever divulge your prior salary to any employer. Because as soon as you do, you destroy your ability to negotiate. It's the equivalent of inviting your prospective employer to judge you by the standards of your last job. Which is utterly insane."

"Wouldn't it be great to employ the master/apprentice model known since the middle ages? Why do we allow inexperienced people to mess around with the most important thing in software, which is the code? I think a well motivated apprentice working alongside with a good master will evolve into a true master himself over the years."

"Technology tends to separate normal from natural. Our bodies weren't designed to eat the foods that people in rich countries eat, or to get so little exercise. There may be a similar problem with the way we work: a normal job may be as bad for us intellectually as white flour or sugar is for us physically."
