i’m ten pages into an ethernet-phy manual and i’m pretty sure the internet is impossible bike

twitter and facebook admit, that at least 10 percent of the user base is likely bots. it’s “official” data, but that article shows, that this estimation may be way undersized. it seems that next dot-com bubble slowly grows and should burst soon. we’ve been discussing this for years now, but it seems the valuation of seemingly worthless, virtual companies producing software is growing year by year. 3 billion dollars for company that builds (poor, by the way) headphones - Apple buys Beats Electronics. but, Beats Electronics at least tries to build something! Facebook just bought WhatsApp for 19.4 billion dollars, that’s about five Nimitz-class aircraft carriers (US has 10 of these), or five and half times more than world health organization spends on food and its distribution in Africa. ...

while looking through recent IETF meeting notes i found interesting idea - splitting OSPF area zero without incurring outage. it’s very interesting idea for flawless, in-service migrations. on the other side, another OSPF concept that I was afraid somebody will bring up is… enabling FlowSpec capabilities. oh my… also, overlay networking effort is gaining grounds, with architectural choices as well as security. it’s interesting how much longer it will take. the I2RS interface is moving forward as well, which is a good sign. problem space is enormous, but progress here means we’re closer to deploying vast number of different SDN architectures. ...

…on the performance of virtualized network stack different cloud providers. plus - couple of slides and some speculations about how AWS is built.

…people using dialup connections. those poor people stay need them to take advantage of restricted Internet services provided by AOL. a year ago at that time, still around 2.6 million of US citizens were connecting to internet that way. …and you think that your 1Mbps upstream link is not enough? ;P

it’s better not to know, how thick the wall is. you may have too short run. anonymous

quite recently i described my own new workstation. it has dual Xeon processors, and today i decided to upgrade memory from 128GB to 256GB (yeah, i use to run a lot of VMs). so below you can see the outcome - 256GB RAM, 2 physical CPUs, 16 cores, 32 threads: great advantage of having such beast at your disposal is that you simply can run everything thrown at it. it’s quiet, it’s effective and it also doubles as great gaming station. on the other side, i’m constantly asking myself a question - “which part of ocean i’m warming up right now?”. ...

don’t start your php upgrade at 2:40 in the morning. as you’ll stay awake until 5am :)

Jennifer Lawrence phenomenon (i can’t quite get Hunger Games popularity, but i love Silver Linings Playbook. how you should do proper conference badges (oh yeah, we’re learning!), Department of Defense outsources to private company management of their own images and movies archive for 10 years, RSA accepted 10M$ of bribe from NSA to promote weaker encryption algorithm and last but not least - DARPA vision of autonomic SkyNet network from eightees. and to sum it up - how to deal with the fact that what you do in your daily job, may not be the thing you love. from my own experience i can attest, that you should strive to find job you’ll love and treat it as a hobby (while this may lead to blurring time between work and private life, and in effect - turning into workaholic). ...

Christmas are coming, and traditionally that means good time of the year to push people to buy things they don’t need. in Poland, companies generally don’t care what Customer wants. and don’t listed in the process of ignoring him/her. why are companies selling services choose not to listen? they don’t care? i was talking about this paradox during Cisco Connect, but in reality i was just repeating what everyone sane enough to think shouts left and right - we want customized offer, not something off the shelf. true value that people appreciate and will be loyal is created by listening to what customer wants - and giving to her/him what they really need (it’s actually pretty complex, but that’s basic intro to subject). ...
