Although written in the same vein as all those articles about Tim Cook where the collective discourse was invariably framed by the comparison to Steve Jobs and his legacy, published for much too long after Tim became Apple’s latest CEO, here such a format actually felt appropriate as the author — taking from Yukari Kane’s upcoming book Haunted Empire, Apple After Steve Jobs — did so to contrast the two very different leadership styles of ..

This is a guest post by my colleague Adam Lelkes. The goal of this primer is to introduce an important and beautiful tool from probability theory, a model of fair betting games called martingales. In this post I will assume that the reader is familiar with the basics of probability theory. For those that need to refresh their knowledge, Jeremy’s excellent primers (1, 2) are a good place to start.

Incredible — I can only imagine what it’s like to drive in this race, at these speeds, on this terrain, and in these vehicles. Definitely adding this one to my bucket list; wow. Permalink.

Fantastic take ostensibly on the problems facing podcasters with regards to discoverability, but in reality a thinly-veiled critique of all those who complain about having the greatest undiscovered app, show, or website rather than focusing their efforts on bringing that undoubtedly exquisite labor of love to a broader audience. I have fallen into this trap in the past, so having a slap-in-the-face reality check like this one to keep me foc..

Very few people actually enjoy Mondays. If you’re in the majority, I’ve got the cure for you: check out Andy Martin on Vimeo , where he posts delightfully weird short animations. My favorite is easily Selfie , and if you enjoy that one The Welsh Egg Choir and his The Plants series are both great ways to spend a few extra minutes blissfully unaware of the drudgery that is the first in a long succession of nine-to-five days. Enjoy. P..

Just as early nineteenth century Americans took Britain’s manufacturing process, improved upon it, and quickly outpaced the nation from which they originally learned from, so too it appears China learned from the early mistakes that befell American internet companies, improved upon their flaws, and now seeks to outpace the country from which they drew those original lessons. So says this article from Digits to Dollars , anyway, and after r....

Is "Fake It 'Til You Make It" The Reason We're So Screwed?

The “fake it ’till you make it” mentality and impostor syndrome are closely linked, in that the former is often cited as a solution to the latter. Especially in the creative professions, where impostor syndrome seems nearly as common as clicky keyboards, many advocate overriding that feeling of inadequacy with a philosophy that accepts it as a given and pushes you past it: you may feel like an impostor — a fake — but that’s okay, because yo....

I have long wanted for a place I could link to great podcasts and point out particularly spectacular episodes, but neither my site nor my now-deceased newsletter seemed like the appropriate venue for such posts. Nevertheless, for especially noteworthy shows, I have broken this unspoken rule and linked to Exponent’s The Garbage Truck Song , for example, and The Weekly Briefly’s A Writing Guide . Yet although I did occasionally point out an..

Figure 1: Docker Docker is an interesting cgroups -based virtualization alternative that uses containers to deploy applications. Docker and solutions like it are useful because: Application deployments occur in identical environments, eliminating per-host quirks Process isolation strategies incur lower overheads than emulating hardware devices Images can be built, shared, and re-used in a repeatable way Lately I've been ....

I’ve also been taking a Karate class for the last two years, and recently it helped me reflect not just on my phisical strength and flexibility but also on my mental strengths and weaknesses. Practice usually consists of three parts. First part “kihon” covers basic movemets such as stances, blocks, punches and kicks. They might look simple to do from the side but require mastering of a lot of details. The second part “kata” - forms, cons....

This week I finally fixed my water code to allow finite bodies of water like this: (It's so dark because I still have a pesky rendering bug) I also realized I accidentally had pre-multiplied alpha turned on for my cloud texture. Here's what it looks like when you use pre-multiplied alpha incorrectly: And here it is fixed (I also made the clouds fade in over distant objects):

Edit 2017: With the change to AzureRM this approach need some tweaking, see this new GIST for how to allow AzureRM to execute commands in Powershell jobs. The script itself is used to remove deployment history for a resource group but can easily be edited to work on VMs. So I’ve got a demo that I’ve put together that uses a LOAD of Azure VM’s to demonstrate scripting against them. To make sure I don’t get charged for them while I’m n..

I have a very light issue for you this month, unfortunately: precious little caught my eye over the past few weeks. In fact, just two articles did, and only one came from Cabin Porn: a third-generation hand-made cabin from Michigan . This structure, to me, defines the genre: built of wood and stone and out in the middle of the woods, not some modern architecture retrofitted into a rustic getaway a few hundred feet from the nearest road, th..

I sat down to catch up on some long-overdue reading with Sid O’Neil’s recent article Earn Your Tools the other day, and before I knew it I had gotten sucked in to the world of every day carry. When I finally resurfaced and finished Sid’s article, after embarking upon more tangents than I could possibly remember along the way, I found myself wholeheartedly agreeing with him: all too often, especially in Boy Scouts, I see kids touting som....

Being in the job market again I been doing quite a few tests. Since I have already put in the effort to a test without result I thought I would post it here. The test involved producing output from a supplied CSV input file which contained insurance claims. Something about taking the input and using it to predict future claims. Please forgive my explanation as I am not a financial expert. Anyway the idea was to take an input such as the f..

Late last year I linked to another, similar post from Huckberry on the Filson 4X4 . Like Filson’s modified Jeep, Starwood Motors made significant modifications to this once-run-of-the-mill vehicle, transforming it into something remarkably cool — perhaps even cooler than its impressive cousin, also linked in Huckberry’s post, the Starwood Full Metal Jacket Jeep . Although at $72,888 and $107,000, respectively, both will remain far outsi..

Worthwhile distinction to be aware of not only for those targeted by tech company announcements, but those writing about them as well. All too often tech writers use these and countless other terms interchangeably when in reality, they are nowhere near synonymous. Permalink.

Interesting examination the of story ranking system Hacker News employs, and much more scientific than my previous attempt . Ken Shirriff’s earlier article on the topic, Inside the news.yc ranking formula — in case you miss the link in his latest post — , also warrants some attention as both try to explain the fickle and near-inscrutable internet fire hose that is Hacker News. I found these two articles especially interesting given a r..

In analyzing a business I commonly look at reports that have two lenses, one is by doing various cohort analysis. The other is that I look for Month over Month or Week over Week or some other X over X growth in terms of a percentage. This second form of looking at data is relevant when you’re in a SaaS business or essentially anythign that does recurring billing. In such a business focusing on your MRR and working on growing your MRR is ho....

So far on this blog we’ve given some introductory notes on a few kinds of algebraic structures in mathematics (most notably groups and rings, but also monoids). Fields are the next natural step in the progression. If the reader is comfortable with rings, then a field is extremely simple to describe: they’re just commutative rings with 0 and 1, where every nonzero element has a multiplicative inverse. We’ll give a list of all of the properti..

Somewhat interesting article explaining the reasons behind the aspects that lead many to consider academic writing so terrible. For the most part, I agree: in my experience, the academic community — or, at the very least, the subset involved in literary pursuits — is incredibly out of touch with not only current trends in their professed field of interest, but averse and close-minded to change in that field as well. This is especially true ..

Try — I say “try” fully aware of the fact that few of you will even try, let alone succeed — to disregard your own personal beliefs when reading this article and it becomes an interesting social commentary on rationality and hypocrisy. I have seen both sides Michael Schulson describes take their beliefs to their respective extremes over the years, to equally ridiculous and ineffective results. If nothing else, read this article, stick it in..

I’m currently running a Tiny Tiny RSS -Server with nginx as a webserver and MySQL as a database-backend. I already wrote about the setup here .

Initially I wanted to migrate the database-contents but it turned out to be more work than expected with little to no benefits. The reason for that is that ....

Theres no doubt that the 9.4 release of PostgreSQL will have some great improvements. However, for all of the improvements it delivering it had the promise of being perhaps the most impactful release of Postgres yet. Several of the features that would have given it my stamp of best release in at least 5 years are now already not making it and a few others are still on the border. Here’s a look at few of the things that were hoped for an....

Apple acquired another company — great, wonderful; the most interesting news I saw after this announcement, however, came from Federico Viticci when he highlighted a recent idea MG Siegler put forth before Christmas in suggesting a Beta App Store.

In the past, most IT admins have put their faith in systems and SANs (Storage Area Networks) that use RAID (Redundant Array of Inexpensive Disks) technology. RAID can be used to combine hard disks together into simple volumes (called RAID-0, or JBOD) that aren’t fault tolerant, but can also be used to create mirrored volumes where both drives are identical in case one fails (called RAID-1), or striped volumes with parity where data is writ..
