Improved default settings for Linux machines
The reason I set [the kernel limits] high is that the machines I work on are not multi-user in any way. […] There's only one user/application that pretty much never wants or expects to hit the ridiculously low default limits. [… I] have never seen them cause an issue; in fact quite the opposite happens: users are not surprised by silly limits like 1024 file handles or applications going away for non-deterministic amounts of time while the kernel fetches application pages from swap that were only swapped out to make room for VFS. […] These are improved defaults for opening up the Linux network stack. I recommend Googling "Linux C10k" to learn more about what they mean. […]

Environment Variables Considered Harmful for Your Secrets
The environment is implicitly available to the process. It's hard to track access and how its content gets exposed. […] The whole environment is passed down to child processes (if not explicitly filtered) which violates the principle of least privilege. So your secret keys are implicitly made available to any 3rd-party tools you're using (like ImageMagick to resize an image). It's hard to say what those 3rd-party tools will do with the environment, especially in rare occasions like crashes.

Toward Better Master Passwords | Jeff Shiner @ AgileBits
[To] get the most security out of it, you should combine Diceware with your own private system. Create a short random password, including digits and symbols and use that in place of one of the dicewords in your final password. So going back to my dogs, Molly and Patty, I might create a weak password like “2dM&P”, and suppose my rolls of the dice gets me “cleft cam synod lacy”, I could then create a master password like “cleft 2dM&P cam synod lacy”, which would be a very good master password.

Why diversity matters (the meritocracy business) | Eric Ries
And yet, when I suggest this practice to hiring managers and recruiters alike, they rarely do it. Hiring managers say, “the recruiter would never go for it” while recruiters say, “the hiring manager won’t accept it.” What I think we’re really saying is: “I don’t want to know if I am biased.” That’s understandable – it’s embarrassing! Even if our biases are only implicit and not consciously held, the systems we build can still contain bias. When we change a hiring policy, especially if we do it in a visible way, we reap two benefits. We actually improve our hiring process and also signal our commitment to meritocracy.

Racism And Meritocracy | Eric Ries @ TechCrunch
I previously described on my blog one simple change I made to the hiring process at my last company. I asked all of our recruiters to give me all resumes of prospective employees with their name, gender, place of origin, and age blacked out. This simple change shocked me, because I found myself interviewing different-looking candidates – even though I was 100% convinced that I was not being biased in my resume selection process. If you’re screening resumes, or evaluating applicants to a startup school, I challenge you to adopt this procedure immediately, and report on the results.
I asked if they were planning to apply. Their response: “oh, no, it’s a waste of time. Y Combinator doesn’t accept people like me.” Where did they get that idea? Surely not from YC’s partners, who as far as I can tell are scrupulously fair in their dealings with entrepreneurs. Rather, they got that impression by inferring that there is probably implicit bias in YC’s admissions process, and that they’d be better off spending their time doing something else other than applying to YC. […] There are qualified minority applicants who are choosing – rationally – to invest their time and energy elsewhere.

The best answer requires some aggravation | Havoc Pennington
• I thought I had a pretty good approach, or didn’t think anything better was possible, and wasn’t looking to spend more time on the problem.
• Someone had the passion to keep pushing, and we either stayed in the room or kept the email thread going beyond a “reasonable” amount of effort.
• We came up with a much better approach, often reframing the problem to eliminate the tradeoff we were arguing about at first.

[…]

A feeling of harmony or efficiency probably means you’re making a boring, routine decision. Which is fine, for routine stuff. But if you have an important decision to make, work on it until the whole team wants to kill each other. Grinding out a great decision will feel emotional, difficult, and time-consuming.

Editing/Publishing Separation | Martin Fowler
Editing involves small number of people frequently accessing the article, doing both reads and updates. Publishing involves many more people (we hope) accessing the article, but all doing reads. […] With two such different access paths, a few CMSs keep separate copies of the articles, controlled by relatively independent modules. The editing module is geared around the frequent updates, it provides support for editing, tracking changes and monitoring the workflow of the editing process. When an article is published it’s copied over the publishing module. The publishing module treats the article as largely read-only, updated rarely and only by the editing module. Consequently the publishing module is designed around serving that article to a large number of readers. At the least this involves a different configuration of the data storage.

Stuff I said at Kansas City StartupWeekend that sounded smart | Avery Pennarun
There’s already really powerful software that does [graphs of statistical data], but nobody in your market segment uses it for some reason; maybe it’s too hard to use or too expensive. That software is your competitor, right? Wrong! That software is irrelevant. Your customers don’t want it, so even if it’s competing with you, it’s already lost. Your customers are probably using either Microsoft Excel’s horrible chart features, or giving up and just not making charts at all. So your competitors are Microsoft and apathy, respectively. Apathy is probably going to be the tougher one.

Premature Ramp-Up | Martin Fowler
More than once, I’ve come across projects who added too many people too quickly. This manifests itself in a breakdown of the cohesion of the code base itself. Duplication runs rampant, […] because the new people don’t understand how the code base currently works, so they do something at odds with it, like adding a competing framework. […] These problems then reinforce each other because nobody can find a consistent way to do things, the Broken Windows syndrome kicks in and you get a positive feedback loop. […] On top of this an overly rapid ramp up leads to a break down of the human communication mechanisms. It takes time for people to get used to working with each other

Mitigating Dangling Pointer Bugs Using Frame Poisoning | Robert O’Callahan
Exploiting dangling pointers is essentially about exploiting type errors. […] Our approach is to prevent the first phase of the attack by making it impossible to overwrite fields of deallocated objects with values of the wrong type. We do this by ensuring that whenever the memory used by a deallocated frame object is reallocated to a new object, the new object must always be exactly the same type as the old object and at exactly the same address.

LCA: How to destroy your community | LWN.net
If you are a corporate developer, you’re likely to realize early on that free software development communities are a pain. They’ll mess up your marketing schemes by, for example, taking the software into countries where you have no presence and no plans. They’ll interfere with product roadmaps with unexpected innovation, adding features which you had not planned for the next few years - or, worse, features which were planned for a proprietary version. Free software communities are never satisfied; they are always trying to improve things. They tend to redefine partner and customer relationships, confusing your sales people beyond any help. And they bug you all the time: sending email, expecting you to attend conferences, and so on. Fortunately, there are ways to get rid of this community menace.

If you’re looking for miniature cities, glass flowers, books bound in human skin, gigantic flaming holes in the ground, phallological museums, bone churches, balancing pagodas, or homes built entirely out of paper, the Atlas Obscura is where you’ll find them. ¶ The Atlas Obscura depends on our community of far-flung explorers to find and report back about the world’s wonders and curiosities. If you have been to, know of, or have heard about a place that belongs in the Atlas Obscura, we want you to tell us about it. Anyone and everyone is welcome and encouraged to nominate places for inclusion, and to edit content already in the Atlas.

Tracking 2 branches in git-svn | Ka-Hing Cheung
The git-svn man page is less than helpful about how to track 2 subversion branches (actually, trunk and another branch). Typically trunk is the development branch and you have another branch for release that you backport fixes to. You can fetch all branches easily, but many times you don't want to and just want a particular branch. After many tries I've found something that works.

The Zen of Comprehensive Archive Networks
There is no magic. All it takes is a few people that sit down and get first something running, a rough cut. Then iteratively enhance it. Don’t try to create a master plan that will get everything right in one fell swoop. The only one that will get swooped is you.

Good News for People who Hate Bad News | Jason Calacanis
Rafat Ali started PaidContent while working for me during the down market. He asked me if it was OK and I said “yeah, sure… that blogging thing will never go anywhere.” He sold it for $30m earlier this year after six or seven years of hard, hard work. Fortunes are built during the down market and collected in the up market. Now’s the time to build, so turn off CNBC and forget the Dow. It’s meaningless to you now. All that matters is your work and your personal progress. Eyes on your instruments please.

Design Rant | Owen Briggs, 2001
My point is I didn’t view this page as a layout first. I let the content inform the structure. I looked to the message to decide what the enhancement should be for visual layout. That’s the trick: let your message inform each enhancement. And as each enhancement relates back to the core it’s fairly easy to not lock out any browser type, because your message doesn’t end up in an enhancement layer – it stays in the core.

“Reply-To” Munging Still Considered Harmful. Really. | Neale Pickett
People still using [_'Reply-To' Munging Considered Harmful_ by Chip Rosenthal and _Reply-To Munging Considered Useful_ by Simon Hill] to debate the issue are wasting everybody's time. The issue was definitively settled [by the IETF] in 2001, and Chip won.

Re: Tradeoffs of XML encoding by enclosing all content in CDATA blocks | Michael Kay @ xml-dev
If you go down that road [of putting pragmatism first and correctness second], you don’t know when to stop, and you end up shipping garbage.

Cure for the common cold | Danny Ayers
Nobel Prize winning chemist Linus Pauling was a big advocate of vitamin C megadosing for not only the common cold but even for cancer. Although the chemical is accepted as a necessary component of diet, and is known to act as a antioxidant and general cell detoxifier, Pauling lost a lot of credibility due to his claims. But it does seem likely that many of the clinical trials that followed (and allegedly disproved) his claims were suspect […] The vitamin is remarkably non-toxic […] To conclude, while I can only offer one little anecdote and some circumstantial info, if you find yourself with the snuffles coming on (’tis the season), high doses of Vitamin C could be worth a shot.

Git Hooks | Benjamin Meyer
Files in the .git/hooks directory are not part of the repository and so they are not tracked. A workaround is to have a git_hooks directory at the top of your repository and symlink .git/hooks to git_hooks whenever you clone.

Re: HTTP cookies as unconditional violations of REST | Eric J. Bowman @ rest-discuss
Every Web cache I’m familiar with, when encountering `Vary: User-Agent`, will create separate entries for every `User-Agent` string it encounters, for IE alone the possibilities are almost endless. […] By storing the coarse-grained result of content negotiation in a cookie, and responding to requests with this cookie by sending `Vary: Cookie` instead of `Vary: User-Agent`, the cache alias problem is cleaned up

How to say “I don’t know” effectively | Andy Lester
Please don’t use the clichéd answer “No, I don’t, but I’m a quick learner!” It’s good to try to turn a negative into a positive, but “I’m a quick learner” is meaningless because anyone can say it. Use one of the three above.

Losing weight, work, and what I’ve been up to | Scott Walters
It’s a pain, but you eventually memorize the calories for things you eat often, or drink. […] I guess it boils down to a few things: not defining hard success/fail conditions but just working on improving; slowly acclimating to less rich and less sugary foods and not trying to force the matter; learning about the food value (nutrition and calories) not only of the foods you presently eat and like to eat but of alternative foods and strange things you might never have heard of, like hominy; learning about your own habits and mechanisms and how you relate to food and different foods so that you can optimize intelligently.

When’s framework overhead justified | Rafe Colburn
If jQuery is already available, the barrier to writing new features is much lower than it is when writing those features from scratch, and I don’t have to revisit the decision whether or not to add a framework at that point. It becomes a tougher decision when you already have non-framework code in place.
