jkat··on Updating Your Utility Belt
"every self-respecting geek has one"

I realize Jeff's just being...poetic, but really it's just an excuse to buy toys. Spend your money on what makes you happy. If more gadgets, or that 6th purse, or 20th pair of shoes does that, great. If you want to define [part of] yourself by your possessions, do that. But don't judge others by the lack of theirs.

jkat··on How do Nobel laureates spend their prize money?
Heard many similar stories about extreme home makeover where property taxes would climb by 3-5x after the renovation, forcing people to foreclose.

I'm under the impression that there was eventually a successful reform effort to have renovations made in the name of accessibility tax-free.

jkat··on Smoothies and fruit juices are a new risk to health
"feeling great" != healthy; "not fat" != healthy

A calorie isn't a calorie. The impact that 100 calories of vodka has on your body vs, say, 100 calories of Kale is significant. The body uses different strategies to break down different types of molecules. There can be toxins. There can be impact on the gut flora. Not to mention the impact that these all have on the feeling of "fullness" (which the article mentions).

jkat··on Xiaomi Makes Another Big Move in Consumer Electronics
With their supposed interest in expanded outside of China, does anyone know if they are hiring? To me it is, by far, the most interesting startup right now.
jkat··on 22k more signatures needed on the Snowden pardon petition
I strongly disagree with it, but it's been stated a few times that it's ok to use downvote if you disagree (1). This is certainly not a new thing around here...

jkat··on OVH acknowledges back office security issue
21 character reset was generated via 3 separate functions each generating 7 characters each. 2 of these were old and weak, resulting in a URL that could be brute forced.

Once discovered, they analyzed 3 years worth of logs to see who was exploited (not clear how they matched it..maybe scanning for brute forces?) and found 3 sites all related to bitcoin.

The weakness in the algo has been resolved by using a 2 real random functions to generate 64 random characters

jkat··on How to eat healthily on £1 a day
As a bad but persistent cook, I'm convinced eating healthy is generally cheaper. A lot of the healthier food I eat is cheap: legumes, [sweet] potatoes and other root vegetables, broccoli, bananas, oranges, water, eggs, oats, frozen vegetables (spinach!), brown rice, tomatoes (canned if not locally cheap). I think people intentionally mix up expensive with more work...
jkat··on Windows Blue under the hood: MinKernel and BaseFS
Possibly pedantic, but this can't be described as reverse-engineered.
jkat··on Who Has the Guts for Gluten?
Let's just say I wouldn't have wanted to be a tonsil in the 80s living in Canada. I assume it wasn't Canada-specific though, anyone confirm?
jkat··on Who Has the Guts for Gluten?
A nice piece which stands in stark contrast to the alarmist and shallow FUD that so often accompanies this topic.

It's amazing how little we know about nutrition and biology. A lot seems to come down to common sense: breast feeding is good, exposure to microbes is good, being overweight is bad.

Hopefully the era of tonsil-removing and antibiotics overdosing is behind us

jkat··on Chinese Army Unit Is Seen as Tied to Hacking Against U.S.
Thanks for the explanation. Hopefully we can agree that it still puts the US in a precarious public spotlight...not sure that the public will make as detailed a distinction as appears to be required.
jkat··on Chinese Army Unit Is Seen as Tied to Hacking Against U.S.
Does the US risk being seen as a dog with a loud bark but no bite here? If you're going to make pronouncements that hacking will be considered an act of war (1), don't you kinda paint yourself into a corner when you get hacked?

jkat··on Heroku Blog: Routing Performance Update
Depending on what side of Hanlon's razor you fall, the only conclusion I get from this is that they are either incompetent or dishonest. I have a very hard time believing that this issue remained unknown to them for years.

As for the post, it's pretty much just documentation. I didn't see any apology. And the only promise of a better tomorrow is a vague "Working to better support concurrent-request Rails apps on Cedar".

jkat··on Amazon Route 53 Introduces DNS failover
Would be nice to have the ability to set up some type of alert/notification.
jkat··on Why I Like Go
I didn't realize NuGet let you do remote path import. Nor that it was around in 2004. Nor that it's part of the C# language spec.

Goroutine + Channels are vastly different than the TPL. The comparison is so far off that I can't even come up with a clever analogy. There's more to concurrency than threads, and more to communication than locks.

jkat··on Why I Like Go
it's pretty common..it leverages github pages (1) which itself is powered by jekyll (2)

jkat··on Why I Like Go
Except for the goroutine and channel, and the type system, and the package system.
jkat··on Next Time Your Mom Says Don't Go Out in The Rain, Spray Yourself With This
Was curious what happened if you inhaled it. Nothing specific on their site, but it does say:

    The coating has been found to be safe for use in nonfood contact areas 
    of food processing plants. The coating meets FDA and USDA regulations for those 
    types of applications.
Still curious.
jkat··on Alarm Clock Myth - How to wake up early
My advice: sleep in a room that faces sunrise and don't use blinds.

I've noticed a world of difference between waking up naturally at 7:00 and waking up via alarm clock at 7:00.]

jkat··on Delusions that companies have about the cloud
The cost can be so out of whack that it can become cheaper to hire talent. Two things make this truer: the person might have spare time to do other things, and sensitivity to things that PaaS are poor at: raw processing speed, memory or SSDs.

I've seen it over and over again with SaaS: server monitoring, logs, statistics, ...

We had an internal fight recently about how to manage our logs. Group A wanted to spend thousands a month on Splunk. Group B spent a weekend setting up logstash + kibana and deploying it in production.

Server monitoring? Nagios. Stats? statsd+graphite. Even if you have to outsource setting it up, it'll probably be cheaper from the very first month.

jkat··on Delusions that companies have about the cloud
The delusion I have, which he didn't address, is that the price/performance ratio is atrocious. Sticking with Heroku, the $3200/m Ronin DB could essentially be a 1-time purchase if you are collocating, or 1/10th the monthly price if you go dedicated.

jkat··on Nginx Requests/Second – RaspberryPi vs Amazon EC2
We got a 3930K, 32GB ram with 2xSSDs in software Raid 1 for $169/month.
jkat··on Nginx Requests/Second – RaspberryPi vs Amazon EC2
We just finished doing some video encoding testing on a few different platform and EC2 (along with EC2-based offerings) are considerably slower and more expensive. Although 10x more expensive than a 3930K, a cc2.8xlarge instance was only 1.75x faster.

jkat··on Nokia sold 4.4 million Lumia smartphones in 'solid' Q4 2012
I've never even seen a windows phone (maybe they aren't popular in Asia?)...I remember when they first came out, most reviews seemed to agree it was very superficial and in need of a lot of polish. Has to story changed?
jkat··on Windows Server 2012 features
Hard to take it seriously when they start off by suggesting that the web server, by itself, makes it a good investment. I have nothing against IIS (I think handlers written in C# is a solid feature compared to the alternatives for other servers)...but at best IIS is as good as many free alternatives. Maybe they mean within the context of ASP.NET hosting, but they really should make that clear (and if so, say how, exactly, it's better for ASP.NET).
jkat··on Young People Are Screwed: Here's How To Survive
True, but fields around math, science and engineering have (as far as I'm aware) been rather reliable.
jkat··on Young People Are Screwed: Here's How To Survive
There's plenty of money to be made, it's a question of hard work. Luck? You were already lucky to be born in the western world.

I think education is the answer, but not the type people seem focused on. I'm talking about life skills children can learn from good teachers and, much more importantly, good parents. Work hard, it's important. Learn life lessons, like cooking...all the basics that are more basic than the 3 Rs.

jkat··on Google Withdraws Patent Claims Against Microsoft
I guess I've been living under a filtered bubble...I've used Google as my go-to example as the only big company not using patents offensively (http://cultofmac.cultofmaccom.netdna-cdn.com/wp-content/uplo...)
