pyvpx··on Twitter suspends alt-right figureheads
alt-right by definition is racist and sexist. that is the definition of the alt-right platform.
pyvpx··on Machine learning algorithms
it's not a homework assignment :) thanks for the link. I'm looking to parse a simple but unknown configuration file format deduced only from known good examples.
pyvpx··on Machine learning algorithms
let's say I wanted to learn the grammar of/how to parse a context-sensitive grammar from a 100 or thousands of valid examples -- what's the best approach?
pyvpx··on VodafoneUK says it carries ~10,000TB of 4G traffic a month
I'm curious what is the average revenue per GB of 4G (or mobile data in general). That the entirety of their 4G network bandwidth usage is about 30Gbps (averaged over the month) is slightly surprising to a not-mobile network engineer such as myself.

drug use is highly, highly frowned upon and performers are tested very, very regularly. porn stars are a safer bet than Tinder.

pyvpx··on Tesla reports first quarterly profit in more than three years
the US can't let that happen because the hegemony the dollar has over the world economy would be at a very high risk. Oil is traded in Dollars exclusively. This gives the Dollar some very powerful and unique powers. Saudi Arabia has a strong hold on the OPEC cartel.
pyvpx··on Mirai Botnet Linked to Dyn DNS DDoS Attacks
I thought we wanted ISPs to be "dumb" pipes? or did I not get the new position paper memo...

Putting the burden on ISPs is never going to happen. They are in the business of moving bits. While some, unfortunately, do things like traffic shaping, deep packet inspection, and all other sorts of middleboxes -- that is all for economic purposes. There is not nor will ever be an economic incentive for an ISP to filter traffic traversing their network unless it is directly impacting their operations. and when that happens, they take the most direct and effective route: bit bucket it and notify the offender to clean up their house :)

pyvpx··on Mirai Botnet Linked to Dyn DNS DDoS Attacks
they are shipping criminally negligent software with their products. A future standard should simply require a known, open, secure method for updating firmware to their devices. demanding it be secure from the start is...dangerously naive.
pyvpx··on A Cloud-Scale Acceleration Architecture: FPGAs in Microsoft’s Datacenters
you can get a nice "SmartNIC" from Silicom that has a Tile Gx-72 and a Virtex FPGA on-board. I have no idea how much they cost; only that you can't buy just one :(

pyvpx··on Update Regarding DDoS Event Against Dyn Managed DNS on Oct 21
because a number of high profile sites decided to put all their DNS eggs in a single, vulnerable basket does not make Dyn "critical internet infrastructure" nor this volumetric DDoS attack a "probe"

if you utilize geoip routing features of one provider, it can be difficult to impossible to then ensure repeatable/deterministic behavior on a second provider.

I had a NS1 demo account. And then they stopped doing that, but it still worked. And then I lost the credentials, and now my account is invalid for a password reset :(

well, first thing one does to use CloudFlare is migrate to their DNS. A CF-hosted site isn't going to be using Dyn...

they are cheap compared to Neustar. And Neustar is priced like a Bugatti. Dyn is more Porsche pricing.

more accurately, they don't support the common standard methodologies for transferring zone data between primary and secondary name servers (like NOTIFY, AXFR, etc).

there is nothing stopping you from having Route53 and $others as NS records for your domains. You just have to make sure they stay consistent. Apparently from the linked discussion, there are people offering scripts and services to do just that.

pyvpx··on I Won $104M for Blowing the Whistle But Was the Only One Who Went to Jail
if you assume a 4-5% return on the money, only want to live off the returns (not the principal) and "six figures" (say, $250,000) is enough as yearly, net income...the lowest a person would go is about USD$6.7MM (after tax, of course)
pyvpx··on A tiny PC as a router
it's efficient because the fast path is a very closed-source binary blob running on the hardware. anything the binary blob doesn't support, is going to be "software switched" as it is commonly called.

their shared hosting product is very, very different from their DreamCompute offering. completely different everything, aside from the datacenter space.
pyvpx··on European Court Allows Copyright Owners to Demand Open Wifi Networks be Secured
intelligence agencies have their fingers all over landing stations and internet exchange points (IXPs)

frankly, they don't need an "open" wifi network to get whatever data they might be interested in.

pyvpx··on New DDoS Attack record 1.5+ Tbps
because none of them can and none of them have a financial interest to do so.

Default free providers such at NTT, GTT, Zayo/AboveNet, Level3/Global Crossing, ATT, CenturyLink/Qwest, Deutsche Telekom, Vodafone/Cable & Wireless, and others commonly (but incorrectly) known as Tier 1/"backbone" providers peer with other networks in a settlement free (no money is exchanged, or, on an accounting basis, everything zeros out) fashion because they are "peers" in the strictest sense: same size, same reach, same markets (mostly...)

there is no danger for them in passing bits

pyvpx··on New DDoS Attack record 1.5+ Tbps
ISPs should implement BCP38 (prevention of spoofed traffic originating from their networks, in short) but when a device is compromised, it doesn't necessarily have to spoof traffic at all.

ISPs have thin margins, and get paid to push bits. DDoS mitigation services are extremely expensive not because they are complex or novel but because they require significant resources (both in hardware and in software expertise).

If manufacturers are going to sling "shit" and we can't hold them accountable; consumers are going to buy the polished turds and we can't prevent them plugging it into their networks; and ISPs have little to zero incentive or ability to "filter out the bad traffic" then we're basically looking at a 5-10 year span of increasingly detrimental, expensive, and effective denial of service attacks.

NAT is not a firewall. Full stop.

Many home routers are horrifically insecure with numerous remote vulnerabilities. Many IoT devices have vulnerable and accessible interfaces locally and externally.

pyvpx··on Sweden Wants to Fight Disposable Culture with Tax Breaks for Repairing Old Stuff
are they, though? I have an older (less than 10 year old) Panasonic washing machine and if the ratings of newer machines are to be believed, when comparing with the dedicated water meter I have connected to the current one, a new one might pay for itself in water savings in about 4 years.

I'm just not sure I believe the newer models ratings. mine is much more efficient in water use on paper than what the water meter clearly states.
