How can we make sure we wind up behind the right door when the going gets tough? The answer is: craftsmanship.

How you look at it is pretty much how you'll see it

If the input string is not in the format, change the program, not the character

If someone can change your mind, he has won you over without raising his hand against you. This is the future of warfare.

I later became more interested in equal rights for women in the work place because of what was happening at IBM. One of the women at Remington Rand had previously been a system service girl for IBM during the war. After a system was installed, a system service girl would go out and show the users how it worked. She was the liaison between the users and the computer company. She was married and had been fired to make room for a returning veteran. When the war ended, IBM rehired all of its former employees who had left to join the military, then fired all of the married women with jobs that could be filled by men.

If you aren't destroying your enemies, it's because you have been conquered and assimilated, you do not even have an idea of who your enemies are. You have been brainwashed into believing you are your own enemy, and you are set against yourself. The enemy is laughing at you as you tear yourself to pieces. That is the most effective warfare an enemy can launch on his foes: confounding them.

if you can write "hello world" you can change the world

Inheritance has recently fallen out of favor as a programming design solution in many programming languages because it’s often at risk of sharing more code than necessary. Subclasses shouldn’t always share all characteristics of their parent class but will do so with inheritance. This can make a program’s design less flexible. It also introduces the possibility of calling methods on subclasses that don’t make sense or that cause errors because the methods don’t apply to the subclass. In addition, some languages will only allow a subclass to inherit from one class, further restricting the flexibility of a program’s design. For these reasons, Rust takes a different approach, using trait objects instead of inheritance.

I'm a programmer. I like programming. And the best way I've found to have a positive impact on code is to write it.

...I’m not saying simple code takes less time to write. You’d think it would since you end up with less total code, but a good solution isn’t an accretion of code, it’s a distillation of it.

In languages with a garbage collector (GC), the GC keeps track and cleans up memory that isn’t being used anymore, and we don’t need to think about it. Without a GC, it’s our responsibility to identify when memory is no longer being used and call code to explicitly return it, just as we did to request it. Doing this correctly has historically been a difficult programming problem. If we forget, we’ll waste memory. If we do it too early, we’ll have an invalid variable. If we do it twice, that’s a bug too. We need to pair exactly one allocate with exactly one free. Rust takes a different path: the memory is automatically returned once the variable that owns it goes out of scope.

It has all the right ingredients: rich contents, friendly, personal language, subtle humor, the right references, and a plethora of pointers to resources.

In the last 10 years, we have seen a rise in selfishness: selfies, self-absorbed people, superficiality, self-degradation, apathy, and self-destruction. So I challenge all of you to take initiative to change this programming. Instead of celebrating the ego, let's flip the script and celebrate the heart. Let's put the ego and celebrity culture to sleep, and awaken the conscience. This is the battle we must all fight together to win back our humanity. To save our future and our children.

Is your life story the truth? Yes, the chronological events are true. Is it the whole truth? No, you see and judge it through your conditioned eyes and mind - not of all involved - nor do you see the entire overview. Is it nothing but the truth? No, you select, share, delete, distort, subtract, assume and add what you want, need and choose to.

I think that it’s extraordinarily important that we in computer science keep fun in computing. When it started out it was an awful lot of fun. Of course the paying customers got shafted every now and then and after a while we began to take their complaints seriously. We began to feel as if we really were responsible for the successful error-free perfect use of these machines. I don’t think we are. I think we’re responsible for stretching them setting them off in new directions and keeping fun in the house. I hope the field of computer science never loses its sense of fun. Above all I hope we don’t become missionaries. Don’t feel as if you’re Bible sales-men. The world has too many of those already. What you know about computing other people will learn. Don’t feel as if the key to successful computing is only in your hands. What’s in your hands I think and hope is intelligence: the ability to see the machine as more than when you were first led up to it that you can make it more.

[On identifying talented programmers] It’s just enthusiasm. You ask them what’s the most interesting program they worked on. And then you get them to describe it and its algorithms and what’s going on. If they can’t withstand my questioning on their program, then they’re not good. I’m asking them to describe something they’ve done that they’ve spent blood on. I’ve never met anybody who really did spend blood on something who wasn’t eager to describe what they’ve done and how they did it and why. I let them pick the subject. I don’t pick the subject, so I’m the amateur and they’re the professional in this subject. If they can’t stand an amateur asking them questions about their profession, then they don’t belong. - Ken Thompson

Most improved things can be improved.

One of her secret fantasies had been that, as a girl who could code, she would work in the one place where a geeky fat girl could get dates. It had not been entirely untrue. But as someone had pointed out to her in school, although the odds are good, the goods are odd.

It is what it is because you let it be so.

linux is my kernel programming is my bus

Managers of programming projects aren’t always aware that certain programming issues are matters of religion. If you’re a manager and you try to require compliance with certain programming practices, you’re inviting your programmers’ ire. Here’s a list of religious issues: ■ Programming language ■ Indentation style ■ Placing of braces ■ Choice of IDE ■ Commenting style ■ Efficiency vs. readability tradeoffs ■ Choice of methodology—for example, Scrum vs. Extreme Programming vs. evolutionary delivery ■ Programming utilities ■ Naming conventions ■ Use of gotos ■ Use of global variables ■ Measurements, especially productivity measures such as lines of code per day

More proof that Lynn is still meant to continue with the government programme occurred during the winter of 2000, when she was sitting at a cafeteria table at the area college. It was later in the afternoon when a few people congregated there with books spread out so they could study while drinking coffee or snacking. Many tables were empty, yet after Lynn had been sitting for a few moments, an elderly man sat down across from her. The old man seemed familiar to Lynn, though, at first, she pretended to ignore him. He said nothing, just sat there as someone might when all the tables are filled and it is necessary to share space with a stranger. His presence made her uncomfortable, yet there was nothing specific that alerted her. A short while later, Mac, the man who had been Lynn's handler in Mexico, came out of the shadows and stopped at the table. He was younger than the old man. His clothes were military casual, the type of garments that veteran students who have military experience might recognise, but not think unusual. He leaned over Lynn and kissed her gently on the forehead, spoke quietly to her, and then said 'Wake up, Sleeping Beauty.' Those were the code words that would start the cover programme of which she was still part. The words led to her being switched from the control of the old man, a researcher she now believes may have been part of Dr Ewen Cameron's staff before coming to the United States for the latter part of his career, to the younger man. The change is like a re-enlistment in an army she never willingly joined. In a very real way, she is a career soldier who has never been paid, never allowed to retire and never given a chance to lead a life free from the fear of what she might do without conscious awareness.

Most of the time, we see only what we want to see, or what others tell us to see, instead of really investigate to see what is really there. We embrace illusions only because we are presented with the illusion that they are embraced by the majority. When in truth, they only become popular because they are pounded at us by the media with such an intensity and high level of repetition that its mere force disguises lies and truths. And like obedient schoolchildren, we do not question their validity and swallow everything up like medicine. Why? Because since the earliest days of our youth, we have been conditioned to accept that the direction of the herd, and authority anywhere — is always right.

On est comme des ordinateurs qu'on programme et déprogramme à volonté. Nous nous conditionnons même à nos réussites et à nos échecs futurs.

On two occasions, I have been asked [by members of Parliament], 'Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?' I am not able to rightly apprehend the kind of confusion of ideas that could provoke such a question.

Plans should program proceeding events and not the other way around.

Programming is not easy like Sunday morning, it is silent poetry.

Programmers are not mathematicians, no matter how much we wish and wish for it.

Programming is the act of installing internal, pre-established reactions to external stimuli so that a person will automatically react in a predetermined manner to things like an auditory, visual or tactile signal or perform a specific set of actions according to a date and/or time.

Programming is quite difficult – if you make a mistake, a bug will bother you for the rest of the day.

Programmers are isolated. They sit in their cubicle; they don't think about the larger picture. To my mind, a programmer is not an engineer, because an engineer is somebody who starts with a social problem that an organization or a society has and says, "OK, here's this problem that we have- how can we solve it?" The engineer comes up with a clever, cost-effective solution to address that problem, builds it, tests it to make sure it solves the problem. That's engineering.

Programming is about managing complexity: the complexity of the problem, laid upon the complexity of the machine. Because of this complexity, most of our programming projects fail.

Programming went back to the beginning of time. It was a little like the midden out back of his father's castle.

Programming your mind with positive thoughts each day will go a long way to keep you from allowing external criticism to derail your dreams.

Rust’s central feature is ownership. Although the feature is straightforward to explain, it has deep implications for the rest of the language. All programs have to manage the way they use a computer’s memory while running. Some languages have garbage collection that constantly looks for no longer used memory as the program runs; in other languages, the programmer must explicitly allocate and free the memory. Rust uses a third approach: memory is managed through a system of ownership with a set of rules that the compiler checks at compile time. None of the ownership features slow down your program while it’s running.

Reality really relies on authoritatively regulating Your absolute attention

Second-guessing a decision made by a programming-language designer is the first step on the road to becoming one.

She had a theory that the fear of getting in trouble was what made her not as good a programmer and that, in fact, it was all linked to testosterone, and that was why there were more guy programmers than women. It was a very hazy theory, and she didn't like it, but she had pretty much convinced herself it was true, although she couldn't bear to think of sharing it with anybody, because it was a lot better to think that there were social reasons why girls didn't usually become code monkeys than to think there were biological reasons.

Simple things should be simple, complex things should be possible.

Software testing is a sport like hunting, it's bughunting.

Software development is the process of creating a computer software. It includes preparing a design, coding the program, and fixing the bugs. The final goal of software development is to translate user needs to software product, while continuously improving the team and the process.

Tests are stories we tell the next generation of programmers on a project.

The big optimizations come from refining the high-level design, not the individual routines.

That doesn't upset too many people, but the fact that accessibility restrictions don't enter into the picture has caused more than one otherwise pacifistic soul to contemplate distinctly unpacifistic actions.

The approach shown... is a common pattern for testing exception-throwing behavior with JUnit. @Test public void missingValueRaisesException() throws Exception { try { new Template("${foo}").evaluate(); fail("evaluate() should throw an exception if " + "a variable was left without a value!"); } catch (MissingValueException expected) { } }

The Stack terraforms the host planet by drinking and vomiting its elemental juices and spitting up mobile phones.

The programming of the consciousness is based upon what is accepted or believed.

The real nightmare, worse than the one in which the Big Machine wants to kill you, is the one in which it sees you as irrelevant, or not even as a discrete thing to know.

The most important property of a program is whether it accomplishes the intention of its user.

The only way to go fast, is to go well.
