PKE in a Browser
Filing away for future use: about the Web Crypto API from 2014 (making the info likely too far out of date) and from 2017, a demo encrypted web chat. Apparently the library implements RSA, and is available on Github.
Of course, the worry is that the browsers' implementations are compromised, but in the event someone needs to decrypt an encrypted email, it'd be better done locally. Presuming common PKE methods are supported, that is.
According to a post on StackOverflow, DH was excluded from the Web Crypto API, but ECDH is included. There's a DH implementation in JavaScript available on GitHub, however.

Anonymity
PIA is cool. So is Mailinator.
BitTorrent over Tor is a bad idea because most BT clients insert the IP address into tracker info, and web traffic is bundled with the BT traffic, resulting in piercing the veil of anonymity.
Get a gift card and sign up for PIA using Mailinator. At the very least, one can skirt the DMCA! ;-)

Net Neutrality Noise
Well, this has been open in my browser since...February. Time to dump it into here.
The Daily Caller had an article against NN that linked to Ajit Pai's dissenting statement and has a video with some remarks. The FCC's "Open Internet" (a misnomer if I ever saw one, considering government regulation) page has some of the other remarks as well.
Of course I don't agree with the co-opted version of network neutrality (distinguished in uppercase) because it inserts government into something that's supposed to be open. That ought to cause cognitive dissonance in anyone with a brain. The prior net neutrality was to avoid such interference, and then the FCC picked up the name and changed what it meant. Brilliant. And people are stupid, so they fell for it. Ah well.

The Internet Doesn't Need to Be Saved
Libertarianism.org, the Cato Institute's broad blog on libertarianism, had a piece on "Net Neutrality" earlier this month.

MaidSafe
So I've been remiss in posting lately....
Here's one that's been sitting in my browser for a while: MaidSafe, which I found out about through Bitcointalk. Silly name, interesting concept. Sounds more like what the Internet was supposed to be.

Bitcoin
Of course I'd heard of Bitcoin, but Joe B. at work pointed out that there were ASICs coming out that are supposed to crank the mining hash rate. Butterfly Labs is one of the companies producing specialized machines. (The FPGAs are more interesting since you could repurpose them later, but they have higher power consumption and lower hash rate.)
Seems pretty risky, though, since a bunch of ASICs will probably be coming online at the same time. BFL's FAQ has an entry on this that seems to imply that one could break even in about 6 mo, but that calculation may lowball the impact of the additional computational power; then again, the exchange rate has also risen about 60% since that calculation. In other words, it's a total crapshoot. Another site has a profitability calculator.
There's also a mining hardware chart on the bitcoin wiki. Some people build custom mining rigs using multiple graphics cards, but the hash rate doesn't even come close to the theoretical rate of the ASICs. In that regard, investing in one of those might be more sound. Or it could be better to have the lower rate now before the ASICs come online....

Online Tools
GinzaMetrics' "lessons learned" for 2012 has a list of online tools that they use that's quite intriguing. To wit:
- git / Github (repository & wikis, nothing else)
- WordPress (migrated from Jekyll in order to allow guest blogging / contributors)
- Dropbox
- Skype
- Google Apps
- DynDNS
- Stripe (payments)
- Tumblr (system status)
- HelloBar (system status)
- Wufoo (landing page management system)
- Trello (issue management)
- Google Doc
- Intercom (analytics)
- Mixpanel and KISSmetrics (analytics)
- Exceptional (bug reporting)

PPPoE
When putting an integrated DSL modem into bridge mode (RFC 1483), one loses the capability to access the web configuration of the modem, because the router doesn't pass LAN packets out onto its WAN port. The usual option is to take down the Net connection by unplugging the modem from the router's WAN port and plugging it into a LAN port. Apparently there are a few other options, but none of them are really satisfactory in that they either cause additional latency (through use of a switch between the modem and the router) or route instability (via wacky topology). If using a Linux-based router, there appears to be a way to force the system to pass the reserved address out on the WAN port:
#!/bin/sh #IP Address of the modem, must be a different network from your local LAN. #If you use 192.168.x.x for LAN then use 10.0.0.x for modem, etc (basically, pick a free IANA reserved range) #Obviously you need to configure the actual DSL modem to use the address you select in MODEM_IP. MODEM_IP="10.0.0.1" #IP address that will be bound to vlan1, usually safe to just increment MODEM_IP by 1. VLAN_IP="10.0.0.2" #Setup network interface and firewall rules. ifconfig vlan1 $VLAN_IP netmask 255.255.255.0 iptables -A forwarding_rule -d $MODEM_IP -j ACCEPT iptables -t nat -A POSTROUTING -d $MODEM_IP -j MASQUERADE

Netwealth-e Int'l
So I met the owner of this online business, Netwealth-e International, over at Ikea a few weeks back. I finally checked out his website, but still don't have a good idea of what they do. Weird, I would've thought it should be clear from the pitch, I mean if one wants to line up capital as well as talent.

NSF funds "connect-the-dots"
This is pretty freaky, although not unexpected. I guess I'd better watch out what I post on here. Not! If I don't call things out, that's one less person perceived to be in the opposition.
Democrats are the root of all that's gone wrong in America! "Expel the socialist liberals, revere the Constitution!"

Feedkiller
I was trying to merge RSS feeds for a couple blogs into a single feed that I could import into Facebook. This site Feedkiller supposedly will do that, so I tried it. Not sure yet if it works. My feed is #1509.

Name Tools
My cnet RSS feed pointed me to an article on Usernamecheck, which tipped me off to a service called BustAName. The latter takes several keywords, generates various combinations of the words, and looks up domain name availability. Could be useful.
