Why each Google+ comment should get its own Web address – CNET
Posted by jpluimers on 2017/07/10
Sure, I’d like to be able to spotlight a Google+ comment by sharing a specific Web address. But Google’s social search effort would be the real beneficiary of comment permalinks.
After 5+ years, this is still on my wish list too…

Happy #NoEmailDay – The case of the 500-mile email
Posted by jpluimers on 2017/07/07
Good reading on #NoEmailDay 2017: The case of the 500-mile email [WayBack] on how a sysadmin in the mid 1990s found the cause of not being able to send email further than roughly 500 miles.
The exact mile unit doesn’t matter as it was all approximation. Read the FAQ on the 500-mile email [WayBack]

APOD: 2016 January 25 – Where Your Elements Came From
Posted by jpluimers on 2017/07/07
Explanation: The hydrogen in your body, present in every molecule of water, came from the Big Bang. There are no other appreciable sources of hydrogen in the universe. The carbon in your body was made by nuclear fusion in the interior of stars, as was the oxygen. Much of the iron in your body was made during supernovas of stars that occurred long ago and far away. The gold in your jewelry was likely made from neutron stars during collisions that may have been visible as short-duration gamma-ray bursts. Elements like phosphorus and copper are present in our bodies in only small amounts but are essential to the functioning of all known life. The featured periodic table is color coded to indicate humanity‘s best guess as to the nuclear origin of all known elements. The sites of nuclear creation of some elements, such as copper, are not really well known and are continuing topics of observational and computational research.

Mikrotik RouterOS /ip firewall address-list timeout values sort-of documented
Posted by jpluimers on 2017/07/05
Thanks to ZeroByte answering at [Answered] Where are ip firewall address-list timeout values documented – MikroTik RouterOS [WayBack] which I edited a bit here:
I haven’t seen anything specific to the format of these time tokens, but the firewall add-to-address-list timeout is documented here:
http://wiki.mikrotik.com/wiki/Manual:IP … Properties…It seems to take the same format as any other similar duration-related input I’ve encountered:
- a raw number is interpreted as seconds
You can specify a number as another duration with tokens:
- s = seconds (default)
- m = minutes
- h = hours
- d = days
- w = weeks
A few aspects:
- Tokens can combine be in any order
- Whitespace is ignored
So these are all valid:
2s 2h 2w
1w2d3h4m5s
5s4m3h2d1w
- Days and weeks just get added together. If you specify 1w8d, this is the same as 2w1d
- The last value specified may be in h:m:s format or in h:m (omit seconds)
- Interestingly, if you mix and match, they just get added:
- “1d 2h 12:30” -> “1d 14:30:00”
- Values larger than 536870911 seconds are stored and tracked but when displayed show as 0sec.
(248 days, 13:13:55)- The maximum value is 4294967295 seconds (which is the maximum 32-bit value)
This decodes to: 7101w3d6h28m15s as the largest value….
(7101 weeks is ~136 years counting for leap years, by the way)

It’s from a while ago, but they’ve likely updated the supported motherboards and storage by now.

Tunneling over WebSockets
Posted by jpluimers on 2017/07/04
Just found out about these interesting links I had loved to use years ago, but alas, now I know (:
- How HTML5 Web Sockets Interact With Proxy Servers
- Vpn-ws – A VPN system over websockets | Hacker News
It looks similar to SSL VPN sometimes also called WebVPN:
Then there are non-VPN tunnels through WebSockets:
- covertcodes/multitun: Tunnel arbitrary traffic through an innocuous WebSocket. Clients can ‘see’ each other, resulting in a stealth WebSocket VPN.
- mhzed/wstunnel: tunnel over websocket
Since WebSockets can run over a proxy server you could route any kind of binary traffic through them even in places that disallow non-web protocols or layer-7 inspect https traffic.
Although ops might restrict stuff even further:
- firewalls – How does a network admin block the reverse SSH in company? – Information Security Stack Exchange
- SSH across a Layer 7 Filter · System Overlord
