John Siracusa in an article from 2010, in which he briefly discusses the problem faced by those wishing to enter into blogging. “Of course, now I just spent 20 minutes futzing with Tumblr themes (before giving up when I realized that I won’t be happy with the results without investing many, many more hours) instead of writing the the post that motivated this little excursion in the first place.” For non-technical people, the problem..

The graph is among the most common data structures in computer science, and it’s unsurprising that a staggeringly large amount of time has been dedicated to developing algorithms on graphs. Indeed, many problems in areas ranging from sociology, linguistics, to chemistry and artificial intelligence can be translated into questions about graphs. It’s no stretch to say that graphs are truly ubiquitous. Even more, common problems often concern ..

Release includes, by popular demand: Improved the visuals - header space shrunk, overlaps fixed and nicer pics. The return of the small live tile - too small for me but people wanted it! Offline access - In testing at the moment. Swiping to move to next story. Minor Bug fixes. Clearer disclaimer .

The following question was asked on Stack Overflow: I have heard some strong developers say that “inline SQL in and of itself is not evil”. I do not understand how inline SQL is acceptable. To me its just like hard coding. Many a developer would scoff in my face for putting a connection string in the code vs a config file. So why is it that “SELECT value1,value2 FROM TABLE” is perfectly acceptable in compiled code?

Another article I glossed by a few weeks ago only to come back to it as the clock strikes midnight. “The changes to my working (and sleeping) routine have forced me to write when it’s time to write, not when I feel inspired.” At the time I didn’t understand the concept of writing when it was time to write rather than when I felt inspired, which is why I didn’t pay a great deal of attention to this article when Shawn Blanc first rele..

When I first saw this tweet roll by in my feeds either earlier this week I didn’t pay much attention to it. As I sit here and it’s nearly midnight, however, John Gruber’s excerpt came to mind: “Midnight: Hunter ready to write.” These days I have very small windows in which to write in: between homework and class during the day, and after I return home from FRC practice at 9:30 (at the earliest) each night. Outside of those small windows, wh..

Certainly one of the most interesting comparison I have seen to a closed nation like Korea scrolled into view in my news feed as an article from The Verge titled Eric Schmidt’s daughter reports on creepy North Korea trip, says the country is like ‘The Truman Show’ . Permalink.

A few days ago in preparation for posting We Have Lost One of Our Own , a short article I wrote eulogizing Aaron Swartz in response to the news that he had committed suicide, I spent some time perusing his work. This article, Take a Step Back, is one of the many I saved to Instapaper, and the one in which I found this interesting tidbit: “There are the blogs on ‘life hacks,’ which are full of gadgets and gizmos that seem to cause mor..

The title reworked for this article, Reginald Braithwaite’s article Why the Fuck? posted earlier today not only made it to the Hacker News front page, but to the top spot. He makes an interesting point to begin with, and then anticlimactically ended the piece with a call to arms in the fight against diabetes and obesity. But that’s his point: today the glamorous projects aren’t the ones helping people. The greatest technical minds of th..

I saw a similar post to this one a few days ago about Microsoft called Fail Fail Fail iPad on Gravitational Pull, using preductions from years long past that coincidentally fit current events to predict the eventual demise of Microsoft. Both articles were wrong. Permalink.

They say that today all companies are software companies. In less than 5 years all companies will be mobile companies. So why isn’t Oracle “getting it”, why aren’t they on the iPhone, on Android and even Windows Phone? This OTN thread has been going on for some time now with people constantly chiming in with various uninformed opinions regarding their desire for an official Java for all platforms from Oracle.

Tea Club was cancelled on Wednesday, so an impromptu belated meeting was held today instead, as all members were conveniently present thanks to a film night. This gave us the perfect opportunity for subjecting unaware participants to a very (un)scientific study.

Earlier this morning Dan Ryan posted The Problem with Kickstarter over on Xconomy. Joshua Beckman of SthgNw commented on the piece, saying, “The problem really is that people sell ideas and are expected to deliver hard products.” I would take Josh’s opinion one step further: the problem is that people sell hard ideas and are expected to deliver hard products.

So hiera wasn’t working when used through my puppetmaster. It worked perfectly when I was running my scripts manually with: puppet apply site.pp but the moment I switched over to regular puppetmasterd usage, everything went dead. I realized a while back, that I could always expect some hiera failures from time to time. Whether this is hiera’s fault or not is irrelevant, the relevant part is that I quickly added:

Speaking of talking about other writers’ tools and processes, here’s Shawn Blanc searching for a replacement to an integral part of his workflow as a writer, Simplenote. Not a day goes by that I don’t use Simplenote, and unfortunately I’ve noticed some of the synching problems he has. Nevertheless Simplenote remains the best on the market, and for that single reason I will continue to keep all my notes, to write all my articles, and to stor..

Always interesting to read about another writer’s tools and setup, and Matt Gemmell’s style makes this piece all the more pleasurable to read. “What you’re seeing through the window is Outside. Now, I’m not a massive fan of Outside, generally speaking - I’m of the belief that we coped with Outside for a long time, until we finally invented Inside, and then breathed a huge sigh of relief - but it can really clear your head and restore so..

Kas Thomas on how to write an opening sentence, drawing on his extensive writing career as well as a number of books on the subject. I particularly liked how he pointed out the openers prominent writers use over and over again. Definitely something to keep in mind when writing. “These aren’t all the possible ways to start a piece, but if you’re completely stuck, one of them should work. If not? Surprise the world with something outlandi..

After the petition to build a Death Star and the petition to remove Ortiz from her position at the Department of Injustice (oops, a typo) all garnered the required 25,000 signatures, I suppose it’s not surprising. Sam Byford has more on this in his post After Death Star and deportation petitions, White House raises signature threshold to 100,000 on The Verge. Permalink.

Thirty-eight minutes and eleven seconds in to the eighteenth episode of The B&B Podcast , Shawn Blanc, in response to Ben Brooks talking about the salient point of his Lion review, said, “If you can’t boil down your whole article into a tweet, what are you doing writing the article in the first place?” Amidst a discussion regarding Ben and Shanw’s recent Lion and Web OS reviews, respectively, this humble observation is easy to miss as it..

An article from Ben Brooks posted in November of last year I had near the middle of my Simplenote list, burried beneath a slew of notes, ideas, and half-baked articles. I’m not interested in writing when it’s not about the writing. iBooks Author is neat, but I don’t want to learn it - instead I’ll just “publish” the book here as a series of posts, where I know what I am doing (somewhat) and where writing is about writing and not layout,..

While many security practitioners use Nmap, few understand its full power. Nmap deserves part of the blame for being too helpful. A simple command such as "nmap scanme.insecure.org" leaves Nmap to choose the scan type, timing details, target ports, output format, source ports and addresses, and more. You can even specify -iR (random input) and let Nmap choose the targets! Hiding all of these details makes Nmap easy to use, but also easy to ....
