PEAK IPV4? Global IPv6 traffic is growing, DDoS dying, says Akamai

Colin Miller

Re: Dummy

I'm a total dummy when it comes to this stuff. Can someone succinctly state how 4 and 6 can get along?

The underlying transport protocol (normally Ethernet) has a byte to indicate that it's carrying an ARP, rARP, IPv4, IPv6 packet, etc.

Can your code survive crappy 2G? This open-source traffic controller will test it

Colin Miller

Already done?

There are already programs that will simulate slow or unreliable connections. See http://stackoverflow.com/questions/1094760/network-tools-that-simulate-slow-network-connection for a discussion.

Netem on a linux bridge can add latency, re-order, duplicate and drop packets. It can do this either at a constant rate or in burst mode, which may be useful to simulate dodgy WiFi or GPRS connections. It can also do it to a different extent depending on which way the traffic is going.

RTFA

It uses the deceleration sensors that trigger the air-bag. If the airbag(s) are triggered, it phones 112 for you. If you are just driving with gusto, it doesn't. Simples.

LEDs turn of-and-on-able?

Can you turn off those LEDs? I can see them getting very annoying, very quickly. I normally put stickers over the power-on LED if they are too bright.

Leaked Windows 10 build hints at peer-to-peer patching

Re: Could be useful... if under control

Even better for enterprises with dozens or hundreds of computers all trying to update at the same time every Patch Tuesday.

Enterprises are likely to be running WSUS which caches the patches.

Hated smart meters likely to be 'a costly failure' – MPs

Colin Miller

Over what time scale?

Over what timescale will the £17 billion level of saving be realised?

There are 26 million households in the UK, according to the 2011 census. If the saving is per household, per year, then that's £654 per household, which is clearly bollocks.

The UK's total annual electricity consumption is 330 billion kWh (in 2010). Electricity generators get paid £0.09 per kWh on average, households pay around £0.13 per kWh. At £0.09 per kWh, the UK's total electricity bill is £29.7 billion. The £17 billion saving is 57% of that. Again the stated amount of money saved is bollocks.

I have ignored gas costs, because (1) I don't have the price or consumption values, and (2) a good chunk of the the gas consumed in the UK is used to generate electricity, which leads to double-counting.

90% of mobile data eaten by TINY, GREEDY super-user HOTSPOTS

Re: "Given that a 4k film can be 300Gb"...

I assume that's studio-edit quality, before being compressed to Blu-Ray quality, at 50 GB for a two layer disk, so around 20-30GB for the film itself.

Downloading 300GB at 10Mb/sec will take the best part of three days.

Random musings

A few random musings.

* It slightly odd that the I²C buses and Analogue ports are numbered from 0, but the digital ports are numbered from 1.

* I hope the power pin-outs on each port are the same, across the port types, so that if you connect a device to the wrong type of port, it doesn't work, but isn't damaged.

* I²C is a bus system, each device has (from memory) a 8 bit address, which is 5 bit class and 3 bit device. Therefore there can be 4 digital ports, with 8 bit output each. Thus, if the LEDs had HEX dip selectors on them, there could be upto 32 LEDs.

* The I²C ports should allow daisy-chaining, or star-topology, subject to power constraints.

All-in-all an useful interesting module. As for it not teaching people how to access a device, why run before you can walk? Adding a UART directly to the data/address bus is the classic way to do it, but is easy to destroy both the CPU, the UART, and anything else on the buses if things go wrong. Anyway, don't modern peripherals for embedded systems come with a SDK, or at least sample code, rather than just a data sheet?

Peppercorn fees?

Surely the publishers are allowed to set what fee they want. If they want to, they can decide to set it a €0.01 per excerpt-view, or €1.00 per annum for unlimited excerpt-views.

Re: To catch this malware ...

You can also use fail2ban.

This is a small script that monitors your logs, for N occurrences of regexp X in Y seconds, from the same IP number.. If this is reached, then it carries out an action, and a second action after Z seconds.

By default it monitors /var/log/auth.log, looking for ssh login failures (either wrong password, or non-existent/no-login user). If this occurs 5 times in 10 minutes, then it will invoke iptables to block all incoming traffic from that IP number to your ssh server, and then automatically unban it 10 minutes later. It can also be set to email you an alert.

It is possible to have it monitor itself, so if the same IP address gets banned 5 times in a day, they get a week's ban (tweak to your inner BOFH's content).

Alabama tops US teacher-pupil sex league

Colin Miller

How to lie with statistics

I notice the stats are given as school-employee-pervs per general-population, rather than school-employee-pers per school-employee.

If a state has more school-employees per general population (wherever because it has more pupils, or more school-employees-per-pupil), this will bias the stats towards that state.

Microsoft wants LAMP for wireless mobe charger

Colin Miller

Re: Fantastic

There's a reason why UV-blocking glass is used for fluorescent lamps, it is harmful to our retinas.

As for solar charging, the Sun gives, on Earth, approx 1kW/m2 of sunlight across all frequencies, when the surface is perpendicular to the Sun. This is largely independent of latitude. A 5.5" 16:9 display is 13cm by 7 cm or about 1/100 of a square metre. If the solar panel can use about 10% of the sunlight (inc non-visible), then it would collect about 1W, which is less than most smart phones phones use when idle.

No cellphones in cells, you slag! UK.gov moots prison mobe zap law

Colin Miller

phone tracing

They could use a dummy base-station, which in turn, impersonates each network. In the GSM and LTE standards, there is no mechanism for the network to securely identify itself to the phone. This will give them the phone's IMEI, and the SIM's IMSI. From there, they can ask the networks to nuke both.

If they are feeling vindictive, they could (ask the network to) check if the SIM has been topped-up via credit-card, or by calling a centre on another phone, and chase after whoever owns them.

Does G.fast allow the modem and DSLAM to change the up/down ratio? I.e. most of the time a home user will have 90% down, but if they start uploading a huge file the modem will notice that it its window is increasing, and then ask the DSLAM to swap to 10% down, 90% up?

Bitcoin laid bare: Boffins beat anonymity

Colin Miller

Re: Does anyone really care

"Anonymous cash also does not attract transaction fees which the Banks thrive on, which is another reason why we must preserve it."

In the UK personal banking is (mainly) free. Companies, however, are charged when they deposit £10/£20 notes, and also when they withdraw £5 and coins. This is why shops offer cash-back on debit-card withdrawals - there is a fixed fee for each card transaction, so cashback costs the shop nothing, and it saves them on the percentage fee on depositing cash at day's end.

In most other countries, there are transaction charges for personal banking.

IEEE turns crank on new wired Ethernet standards

Colin Miller

Re: Why?

10GBASE-CX4 is limited to 15metres, most places that would uses multi-gigabit WiFi (airport terminals etc), will have more than 15metres between the AP and their upstream connection.

The point of the new standard is so that the old cabling won't have to be replaced with new for > 1Gbit/sec wired.

However, biting the bullet and putting in the best fibre-optic links might be more sensible, if any APs can talk directly to fibre ethernet.
