pyvpx··on Germany Tries to Catch Up with Startup World
telephone lines owned by the Government (Telekom, private in theory, owned by the Government on paper), no less!

there is some DOCSIS (cable) service, mostly from Vodafone but also a smaller provider named telecolumbus.

There was versatel, but 1&1 smartly purchased it at what I believe to be an absolute steal. They have what is clearly the widest fiber network reach outside of Telekom, and 1&1 is actually going out there and selling it.

I could, if I really wanted to, get 1Gbps symmetrical for only 500EUR/month. The catch is the ~3000EUR install and minimum 3 year commitment. but, at least the option is there. Telekom, if they have fiber "available" at your address, will offer you 20Mbps for around 700EUR a month, then do this really weird delivery of an STM-1 (155Mbps) circuit, broken out into E3s (45Mbps) to a Cisco ASR1002 (a 5000EUR device, easily), that is converted to a rate limited GigE interface. Oh, and the install fee is about 1200EUR and takes a solid six weeks...but only if you call every day to remind them.

Berlin internet connectivity is a sick and twisted joke.

pyvpx··on Why is this little construction crane illegal in New York City? (2016)
I tried this on my first trip to 60 Hudson (a "famous" carrier hotel in Manhattan). We needed to remove a Cisco 2600 router. It's smaller than a pizza box. It fits in a backpack. I carried it under my arm.

As I step out of the elevator and into the lobby, the front desk person goes "you can't remove that equipment".

No worries, I anticipated this and have all the relevant removal paperwork. He is uninterested.

"you can't remove equipment using the passenger elevators"

But, I am in the lobby. The door is less than 20 steps. I already rode the elevator down.

"you must use the freight elevator. that is the law."

OK, I'll go back upstairs and use the freight elevator. Where is it?

"you can't operate it. you need an elevator operator"

OK, where should I wait for them? can you call one for me?

At this point, let me tell you it is Easter weekend.

"they do not work weekends, and it is a holiday weekend. they are $160/hr, minimum 4 hours, and it is double time on the weekend, plus time and a half for holidays"

OK, I'll just put it back. This piece of equipment is barely worth $400. Then I proceeded to go up the elevator, back to the datacenter, go inside, put the router in my backpack, and go back out.

And at the lobby was one of NYC finest, with one of the security people, who kindly asked me what was in my backpack. Then asked to search it. Do you have a warrant?

"I don't need a warrant. I'll just take you down to the precinct and open it there. You sure you don't have any weed in there, Mr. California?"

I went back up, put the router in the cage, went back downstairs, and used every ounce in my body not to flip the building security and his cop buddy the bird, akimbo style.

pyvpx··on Tunnel TCP Through WebSockets (CLI Tool)
you'd be surprised what a "deep packet inspection" (better known as DPI or L7-aware) firewall can tell. some are quite sophisticated, and there are a surprising number of techniques to identify even encrypted traffic (not the precise payload, per se)
pyvpx··on Comprehensive and biased comparison of OpenBSD and FreeBSD [pdf]
FreeBSD appreciates, but doesn't need donations like the OpenBSD foundation does. many FreeBSD committers are FTE for a number of commercial outfits and work on FreeBSD full time. OpenBSD has hackathons, that are funded by donations.

if you use both, consider donating to OpenBSD first.

if you use OpenSSH, consider donating more to OpenBSD :-)

pyvpx··on Two Executives to Leave Uber, Adding to Departures
because they subsidize every ride. significantly. traditional taxis are actually profitable with what they charge. uber is not.
pyvpx··on Cloudflare Reverse Proxies Are Dumping Uninitialized Memory
as someone who has been involved in a number of moronic ISP designs, operations, and build outs --- asymmetric access networks are designed that way due to actual traffic patterns and physical medium constraints.

you can argue "if everything was symmetric, then traffic patterns would be different" and you might be right, but that's not how the market went or how the "internet" started.

the client-server paradigm drove traffic patterns, and there was never any market demand or advantage by ignoring it.

pyvpx··on The Real Reason Women Quit Tech (and How to Address It) (2016)
Interesting. Now that I think about it, every single one of my networking and/or sysadmin friends have realized significant upward mobility in the past decade. any of my programming friends have either gone freelance or simply changed employers for pay increases.

Are there any public statistics on this?

pyvpx··on pfSense 2.3.3 released
and if you don't need a GUI, you can always install OpenBSD -- no extras required. it includes a useful OSPF and BGP daemon, BFD in the next release (I believe), and a version of pf that isn't a few years old :)

pyvpx··on pfSense: Open source network firewall distribution
what developers have they hired? besides Neville as a consultant for FreeBSD netstack performance improvements.
pyvpx··on pfSense: Open source network firewall distribution
the bespoke part is "what is your definition of down?". is it 10% packet loss? is it physical loss of link? is it something else? is it a combination? is it 15 seconds of $X or a full minute?
pyvpx··on pfSense: Open source network firewall distribution
it doesn't work very well, even for the little OPN/pfSense do.
pyvpx··on pfSense: Open source network firewall distribution
you also dislike many OpenBSD policies, and developers.

P4 language. Truly defining networks via software is currently and will continue to be amazing.
pyvpx··on IPv6 Support for AWS Extended to 15 Regions
well, no. now the excuse will shift from AWS doesn't support IPv6 to Kubernetes doesn't support IPv6 :p

pyvpx··on A Visa for founders, engineers and investors willing to join France
I moved to Berlin almost three years ago, and extended/expanded my company here. I am not a start-up, though I am developing a product, but more of a one-man consulting shop.

Getting a self-employed VISA is not easy unless you have some serious credentials. My partner has three degrees, two post-graduate, from highly regarded US universities; an extensive profile of speaking engagements; a very, very solid financial standing; and a solid business plan. The IHK (who reviews all business plans for self-employed applications) still said "No" but begrudgingly gave the green-light when presented with a book contract from a well known technical publisher.

I have no degrees, but a financially viable consulting business of some years, and a lengthy professional background. Three years later, over 12 foreigners office appointments, a UG (affectionately known as the mini-GmbH) with over 12K founding capital, a high-priced lawyer, over a 120K in USDEUR transfers, and a visit from the police to confiscate my passport over Christmas, my self-employment visa is no further along than the day I first submitted it.

Still, incomparably better than US immigrations. I'm certainly stuck in some weird, exceptional state that has confused even my lawyer.

Consider Berlin. It is wonderful here, definitely. Rents are rising, however, and (sadly, in my opinion) you do not need to learn German. I know of far too many people who have spent numerous years here without speaking more than a phrase or two of deutsche.

If you want to start a company/be self-employed DO NOT follow the (typische amerikanische) DIY process. Factor in costs for tax advisers and lawyers.

pyvpx··on Kubernetes 1.5.0 Released
you'd think such a project so heavily supported by Google would have IPv6 support. Hell, you'd think it'd be native/first-class.

pyvpx··on A “nation-state” used Wikileaks to influence US election, the head of NSA says
baseless? a current, active Russian politician (whose name and position escape me) publicly said 'we might have helped with Wikileaks'

it's far from baseless -- no matter how (correctly) suspicious one is of anything the NSA says.
