We've read so many sad stories about communities that were fatally compromised or destroyed due to security exploits. We took that lesson to heart when we founded the Discourse project; we endeavor to build open source software that is secure and safe for communities by default, even if there are thousands, or millions, of them out there. However, we also value portability, the ability to get your
Of the many, many, many bad things about passwords, you know what the worst is? Password rules. If we don't solve the password problem for users in my lifetime I am gonna haunt you from beyond the grave as a ghost pic.twitter.com/Tf9EnwgoZv — Jeff Atwood (@codinghorror) August 11, 2015 Let this pledge be duly noted on the permanent record of the Internet. I don't know if there's an afterlife, but
Every geek goes through a phase where they discover emulation. It's practically a rite of passage. I think I spent most of my childhood – and a large part of my life as a young adult – desperately wishing I was in a video game arcade. When I finally obtained my driver's license, my first thought wasn't about the girls I would take on dates, or the road trips I'd take with my friends. Sadly, no. I
Eric Raymond, in The Cathedral and the Bazaar, famously wrote: Given enough eyeballs, all bugs are shallow.The idea is that open source software, by virtue of allowing anyone and everyone to view the source code, is inherently less buggy than closed source software. He dubbed this “Linus’s Law.” Insofar as it goes, I believe this is true. When only the 10 programmers who happen to work at your com
I'm a little tired of writing about passwords. But like taxes, email, and pinkeye, they're not going away any time soon. Here's what I know to be true, and backed up by plenty of empirical data: No matter what you tell them, users will always choose simple passwords. No matter what you tell them, users will re-use the same password over and over on multiple devices, apps, and websites. If you are
09 Jan 2015 The God Login I graduated with a Computer Science minor from the University of Virginia in 1992. The reason it's a minor and not a major is because to major in CS at UVa you had to go through the Engineering School, and I was absolutely not cut out for that kind of hardcore math and physics, to put it mildly. The beauty of a minor was that I could cherry pick all the cool CS classes an
In an earlier post on the philosophy of code comments, I noted that the best kind of comments are the ones you don’t need. Allow me to clarify that point. You should first strive to make your code as simple as possible to understand without relying on comments as a crutch. Only at the point where the code cannot be made easier to understand should you begin to add comments. It helps to keep your a
Let me open with an apology to John Gruber for my previous blog post. We’ve been working on the Standard Markdown project for about two years now. We invited John Gruber, the original creator of Markdown, to join the project via email in November 2012, but never heard back. As we got closer to being ready for public feedback, we emailed John on August 19th with a link to the Standard Markdown spec
In 2009 I lamented the state of Markdown: Right now we have the worst of both worlds. Lack of leadership from the top, and a bunch of fragmented, poorly coordinated community efforts to advance Markdown, none of which are officially canon. This isn’t merely incovenient for anyone trying to find accurate information about Markdown; it’s actually harming the project’s future.In late 2012, David Gree
Long-time readers of this blog know that I have an inordinate fondness for GUIDs. Each globally unique ID is like a beautiful snowflake: every one a unique item waiting to be born. Perhaps that’s why I read with great interest recent accounts of people switching their database tables from traditional integer primary keys... ID Value -- ----- 1 Apple 2 Orange 3 Pear 4 Mango ... to GUID keys. ID Val
A little over a year ago, I wrote about the importance of version control for databases. When I ask development teams whether their database is under version control, I usually get blank stares. The database is a critical part of your application. If you deploy version 2.0 of your application against version 1.0 of your database, what do you get? A broken application, that's what. That's why your
In 2007, I was offered $120,000 to buy this blog outright. I was sorely tempted, because that's a lot of money. I had to think about it for a week. Ultimately I decided that my blog was an integral part of who I was, and who I eventually might become. How can you sell yourself, even for $120k? I sometimes imagine how different my life would have been if I had taken that offer. Would Stack Overflow
I had an opportunity to meet Ted Neward at TechEd this year. Ted, among other things, famously coined the phrase “Object-Relational mapping is the Vietnam of our industry” in late 2004. It’s a scary analogy, but an apt one. I’ve seen developers struggle for years with the huge mismatch between relational database models and traditional object models. And all the solutions they come up with seem to
27 Aug 2013 The CODE Keyboard What would you do, if you could do anything? I don't mean in a fantasy superhero way, but in terms of resources. If someone told you that you now had the resources to attempt to make one thing happen in the world, one real thing, what would that be? If you're Elon Musk, the patron saint of Hacker News, then you create an electric car and rocket ships. And then propose
Rich Skrenta writes that code is our enemy. Code is bad. It rots. It requires periodic maintenance. It has bugs that need to be found. New features mean old code has to be adapted. The more code you have, the more places there are for bugs to hide. The longer checkouts or compiles take. The longer it takes a new employee to make sense of your system. If you have to refactor there’s more stuff to m
Tim Berners-Lee on the Principle of Least Power: Computer Science spent the last forty years making languages which were as powerful as possible. Nowadays we have to appreciate the reasons for picking not the most powerful solution but the least powerful. The less powerful the language, the more you can do with the data stored in that language. If you write it in a simple declarative from, anyone
22 Mar 2013 Why Ruby? I've been a Microsoft developer for decades now. I weaned myself on various flavors of home computer Microsoft Basic, and I got my first paid programming gigs in Microsoft FoxPro, Microsoft Access, and Microsoft Visual Basic. I have seen the future of programming, my friends, and it is terrible CRUD apps running on Wintel boxes! Of course, we went on to build Stack Overflow i
Occasionally, startups will ask me for advice. That’s a shame, because I am a terrible person to ask for advice. The conversation usually goes something like this: We’d love to get your expert advice on our thing. I probably don’t use your thing. Even if I tried your thing out and I gave you my so-called Expert advice, how would it matter? Anyway, why are you asking me? Why don’t you ask your comm
13 Dec 2012 Web Discussions: Flat by Design It's been six years since I wrote Discussions: Flat or Threaded? and, despite a bunch of evolution on the web since then, my opinion on this has not fundamentally changed. If anything, my opinion has strengthened based on the observed data: precious few threaded discussion models survive on the web. Putting aside Usenet as a relic and artifact of the pas
Markdown is a simple little humane markup language based on time-tested plain text conventions from the last 40 years of computing. Lightweight Markup Languages ============================ According to **Wikipedia**: > A [lightweight markup language](http://is.gd/gns) is a markup language with a simple syntax, designed to be easy for a human to enter with a simple text editor, and easy to read in
One of the central themes of stackoverflow.com is that software developers no longer learn programming from books, as Joel mentioned: Programmers seem to have stopped reading books. The market for books on programming topics is miniscule compared to the number of working programmers. Joel expressed similar sentiments in 2004's The Shlemiel Way of Software: But the majority of people still don't re
What do you need to do today? Other than read this blog entry, I mean. Have you ever noticed that a huge percentage of Lifehacker-like productivity porn site content is a breathless description of the details of Yet Another To-Do Application? There are dozens upon dozens of the things to choose from, on any platform you can name. Lifehacker's Law: A new To-Do list app will be released every 24 hou
Stack Overflow – like most online communities I've studied – naturally trends toward increased strictness over time. It's primarily a defense mechanism, an immune system of the sort a child develops after first entering school or daycare and being exposed to the wide, wide world of everyday sneezes and coughs with the occasional meningitis outbreak. It isn't always a pleasant process, but it is, u
Look at this incredible thing Ian Baker created. Look at it! What you're seeing is not Photoshopped. This is an actual photo of a real world, honest to God double-clawed hammer. Such a thing exists. Isn't that amazing? And also, perhaps, a little disturbing? That wondrous hammer is a delightful real-world acknowledgement of the epic blog entry PHP: A Fractal of Bad Design. I can’t even say what’s
In A Developer’s Second Most Important Asset, I described how buying a quality chair may be one of the smartest investments you can make as a software developer. 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 whole "everyone should learn programming" meme has gotten so out of control that the mayor of New York City actually vowed to learn to code in 2012. A noble gesture to garner the NYC tech community vote, for sure, but if the mayor of New York City actually needs to sling JavaScript code to do his job, something is deeply, horribly, terribly wrong with politics in the state of New York. Even if
07 May 2012 This Is All Your App Is: a Collection of Tiny Details Fair warning: this is a blog post about automated cat feeders. Sort of. But bear with me, because I'm also trying to make a point about software. If you have a sudden urge to click the back button on your browser now, I don't blame you. I don't often talk about cats, but when I do, I make it count. We've used automated cat feeders s
23 Apr 2012 Will Apps Kill Websites? I've been an eBay user since 1999, and I still frequent eBay as both buyer and seller. In that time, eBay has transformed from a place where geeks sell broken laser pointers to each other, into a global marketplace where businesses sell anything and everything to customers. If you're looking for strange or obscure items, things almost nobody sells new any more,
In the calculus of communication, writing coherent paragraphs that your fellow human beings can comprehend and understand is far more difficult than tapping out a few lines of software code that the interpreter or compiler won't barf on. That's why, when it comes to code, all the documentation probably sucks. And because writing for people is way harder than writing for machines, the documentation
