   When you pay the company for some service and the only way to reach their support is via Twitter, hoping for the best, I'd run away from that company fast as possible. Someone once said, "you are never big enough for Google to not

   Instead of using "this auto&&" trick to get recursive lambdas, I wonder why they didn't go with named lambdas (Clojure made it really nice). E.g. auto factorial23 = [] fact_recur (int n) { if (n <= 1)

   Frink looks great! I usually use Emacs calc [1] for things like this, and since I have Emacs always open, calc can be up in a few keystrokes. But I'll add Frink to my bookmarks for all those friends that are not using Emacs but wants s

   In Chinese culture, copying (I would not use the word "stealing") symbolizes respect for a product and has roots in Confucianism (however, let's avoid potential exploitation of this). But don't forget that Americans beha

    I don't find your examples convincing. Like in banking and finance, everyone is fair until they are proven to be not. For example, Knight Capital, Bernie Madoff, SAC, The Galleon Group, or banks like Merrill, HSBC, Standard Chartered,

    My tool of choice is usually Ansible, so, from the Ansible point of view, deploying to a container, VPS, bare server, or a cluster, looks pretty much the same. I haven't mentioned Swarm intentionally, which IMHO I consider "the ne

    IMHO crypto space is good because the banking sector finally sees they have some competition. And crypto space is global, not tied to country banking sector lobbying (pardon, regulation :P). So, for example, in my country (and I believe man

    My 2c: you don't need K8s unless you are google-scale. Even if you think you are google-scale, you are not. Maintenance-wise and $$-wise, two VPS boxes with Cloudflare (even with an enterprise account) setup is usually cheaper than an

    I'm not a crypto/finance expert, but the current crypto space reminds me of the early US "Free Banking" era. Too many players, wild west, many earners, and many losers. There is a tech & concept value in crypto space

    I've noticed that many startup-like companies are on the margins, living from month to month. Hiring is for inflating value and showing numbers to VCs. If the company is susceptible to even small inflation moves or cannot sustain 6-7 m

    On Linux, you want to check D-Bus [1] if you need IPC (but that is primarily used for message exchange between different desktop apps). Everything else you mentioned sounds like a recipe for bloat. Desktop GUI libraries (like Qt or Gtk) shi

    I'd say "yes and no" from what I could see. If you are looking for a DBA job only in a big/small company, that will be very hard to find. Sadly, most companies will expect you to do DBA work as a "side job" (th

    I'm not sure this is precisely the case. Any platform, except Windows, was pretty much alien for Adobe and Flash - I recall all the pains of running Flash on Linux, even when support on Firefox/Mozilla side was decent. IMHO, Flash

    I'll probably be a minority here, but I'd say: java + Vaadin [1] + raw jdbc (no ORM nonsense). On Vaadin site, you can use starter [2] to create an app template. There is no need to write javascript; most Vaadin code looks like go

    Regarding bootstrap time, have you tried cold PHP, like a cgi script or a PHP script run from shell? Not fast at all. I guess you are comparing PHP with mod_php (or something similar that already has a running interpreter in memory). In tha
