dmiladinovon How RAID-6 dual parity calculation works

From the article:

> This article is for computer engineers who would like to have a high-level understanding of how the dual parity calculation works, without diving into all of the mathematical details.

I believe that is the value proposition for reading: gaining an understanding of RAID-6 parity calculation while glossing over the math-y bits.

dmiladinovon Is TDD dead?

Oh come now, that's just an extra safety net.

Don't take IDEA local history as a replacement to version control, rather a supplement.

dmiladinovon Inverted Polymorphism With Pattern Matching

Without actually saying the words, this post makes a good introduction to the [expression problem][0], trading the ease of adding types for the ease of adding behaviors.

[TINSTAAFL][1], but what a functional programming paradigm takes away it replaces with brevity, concision, additional type safety, and greater opportunities for the compiler to restate your algorithms in a form more conducive to parallelization and concurrency.

dmiladinovon The new PHP

In order to use variables from the scope that the anonymous function came from, you have to explicitly import them into the anonymous function with the use[1] block:

    public function getTotal($tax)
    {
        $total = 0.00;
        
        $callback =
            function ($quantity, $product) use ($tax, &$total)
            {
                $pricePerItem = constant(__CLASS__ . "::PRICE_" .
                    strtoupper($product));
                $total += ($pricePerItem * $quantity) * ($tax + 1.0);
            };
        
        array_walk($this->products, $callback);
        return round($total, 2);
    }

In other languages that have true closures, the anonymous function "closes over" the lexical scope in which it was declared.

dmiladinovon Statement from Edward Snowden in Moscow

According to Wikipedia:

Exile means to be away from one's home (i.e. city, state or country), while either being explicitly refused permission to return and/or being threatened with imprisonment or death upon return.

So he's probably not so much worried about whether or not he can return to the U.S., but rather what would happen to him when he did.

dmiladinovon Clojure core.async Channels

Oh, I wasn't aware that ClojureCLR was still being maintained. All I knew was the Hickey was no longer maintaining it.

Thanks for clarifying!

dmiladinovon Clojure core.async Channels

> Inference : ClojureCLR seems to be dead :(

For at least a few years now.

I remember watching a Hickey talk where I think I recall him saying it was even before 2011, but the exact name escapes me at the moment. However, I was able to find this snippet from 2011:

Fogus: Clojure was once in parallel development on both the JVM and the CLR, why did you eventually decide to focus in on the former?

Hickey: I got tired of doing everything twice, and wanted instead to do twice as much.

Yes, as for the Balkans, some would argue that Croatian, Serbian and Bosnian are all just dialects of the same basic language.

dmiladinovon 21 Months In: How to Manage a Remote Team

> I'd love to see some statistics on what kind of effect a half hour per employee per month does for overall happiness and employee retention.

I would too, and here's some anecdata for you: one of my old bosses would conduct weekly one on one meetings with all of the developers on his team (anywhere from 4 to 8 of us at different times) and I'd have to say that personally they were some of the best manager-direct experiences I've ever had since.

One on one meetings are one of the most important tools out there for helping organizations build relationships with their people, helping them produce more results, as well as increase retention.

Anybody interested in starting them at their organizations should check out the manager tools website. They produce several weekly free podcasts as well as offer other products and services.

dmiladinovon A command line refactoring tool for PHP

PHPStorm is like the perfect gateway drug. I first became familiar with JetBrains products through PHPStorm, but have since upgraded to IntelliJ IDEA. IntelliJ IDEA is the perfect polyglot IDE, with support for the following either in-built or via plugin (and forgive me if I leave anything out, or add it in a reply):

- Java

- Scala

- Clojure

- Android

- PHP

- html/css/javascript

- Python/Django

- Ruby/Rails

- Groovy/Grails

- Actionscript/Flex

I'm a raving fan!

dmiladinovon Love what you do, not what you earn

This.

I used to work at an organization that paid conspicuously less than local market value for comparably experienced developers.

The work environment, however, was a really pleasant one to work in. There were quarterly and annual company-wide events, such as going to local sporting events, scavenger hunts, Christmas dinners at fancy restaurants, and the like.

My boss was great and took an active interest in developing the skills of his team, and successfully tanked upper management, leaving us free to develop in peace. All the developers ate together in our own break room, usually over board games. There was a sense of camaraderie on our team you don't just find everywhere.

I loved working there; though I didn't want to, I ultimately had to leave when I started a family, got a house, and my expenses outpaced my income.

Perhaps I should have left sooner. Perhaps I was unwittingly underselling myself. However, I prefer to think of all of the above I mentioned as "non-cash" compensation.
