Bring back error correction, say Danish 'net boffins

eldakka

Re: Oh noes, please don't do that

warning: IANANE (I Am Not A Network Engineer)

But do we have to rely on the loss of TCP packets to tell us this at the end-to-end level? Couldn't a router send back to everyone who's swamping it a 'back-off' message from the router? I thought there was already provision for this, but it's rarely, if ever, used?

In the early days of of the internet when router processor capability was low, and bridging was more common than routing due to not being able to produce sufficiently intelligent silicon for routers at appropriate cost points, TCP-retransmission may have made sense as a congestion management mechanism. For the TCP layer at the receiver end to keep sending re-transmits, thus implicitly telling the sender to back-off due to the number of lost packets.

However these days where routers have, compared to their early predecessors, massive processing capability, either what was not so long ago server grade CPUs or efficient lightning fast ASICs, can't the router's tell senders to back-the-FEC-off rather than relying on the receiver losing packets and telling the sender? In this case (where routers actually tell senders to shut-the-FEC-up) FEC may make more sense.

I could see a case for adaptive choosing also. Low error-rates, TCP might make sense as retransmission packets are rare, and the FEC overhead (more data to contain the ECC) might perform worse. If there are slightly higher error-rates, and routers are smart enough to tell a sender swamping them to back off, FEC may make more sense, a little bit more data for the ECC, but less than the extra data TCP retransmissions would cause.

If there are high error rates, then maybe another change? Maybe neither TCP or FEC?

Chrome browser has been DRAINING PC batteries for YEARS

eldakka

Err, because some apps that you install might NEED to check state more often than the default? near-real time systems might want to wake every 4 or 5 ms, or even as google chrome thinks it needs to, every 1ms.

Unless you've loaded a plugin into chrome that for some reason needs frequent wake-ups, then there's no reason for a browser to want to wake up more frequently than the defauly.

Re: Regarding the terminology problems...

Even worse, when I'm researching a new phone or tablet and ask questions like "How much menory does it have?" I get answers like:"32GB of memory", "64GB of memory", "128GB of memory".

No, if I wanted to know how much STORAGE or NAND or SSD or eMMC it had, that would be the correct answer. I want to know whether it has 1GB, 1.5GB, 2GB, 3GB etc of MEMORY.

Actually, 3.5" disks ARE floppy.

It's the external casing of the disk that isn't floppy.

Break the rigid external casing of the 3.5" disk, and inside is the component that actually stores the data and it is, well, a disk that is floppy.

If you break the rigid external casing of a Hard Disk Drive, inside is the component that actually stores the data, and it is, well, a disk that is RIGID, non-floppy, i.e. HARD.

You are ALL Americans now: Europeans offered same rights as US folks in data slurp leaks

eldakka

"Such a deal would at least provide Europeans a forum for addressing their grievances in the courts when they feel personal information has been mishandled or abused by authorities."

Ahh, so Europeans will have the same standing as US citizens in addressing their grievances before US courts? i.e. go to court, US gov says all discovery/information is top secret because terrorism, therefore can't be used in the case, judge dismisses due to lack of evidence of wrongdoing.

So awesome news!

SHOCK HORROR: Oz's biggest govt agencies to miss infosec deadline

eldakka
WTF?

2 days? Tell them they're dreaming.

"mandate application and operating system patching

within two days of an update release"

2 days?

How are you expected to do the following in 2 days:

1) Download patch(es);

2) Deploy the patches to an RnD environment to see how the patch process runs, whether it can be automated or requires a GUI and clicking on 'next' buttons;

3) Package/otherwise automate the patch for easy deployment to 100's of servers;

4) arrange downtime for the dev environment to deploy the patch and any restarts that are required;

5) install patch, perform any necessary restarts;

6) Get signoff that the patch hasn't broken anything in dev and can proceed to the next environment;

7) arrange downtime for the integration environment to apply the patch;

8) install patch, perform any necessary restarts;

9) get integration testing team signoff that the patch hasn't broken anything;

10) arrange downtime in the system/performace testing environment to apply patches;

11) apply patches in the system/performance testing environment and perform any necessary restarts;

12) get signoff from testing team that patch doesn't break anything/cause performance issues;

13) arrange downtime for production, including notifying external agencies that depend on your systems, informing other national governments that you have MOUs with stating 10-day notification of any outages to critical systems that they interface with;

14) apply patch and perform any restarts that are necessary;

15) cross fingers and hope no backout is required of the patch thats just been rushed through with limited verification testing.

16) retrofit patch to other non-critical path environemnts - training, other dev/integration environments that are being used for future releases (can have up to 3 streams running simultaneously, current prod, next release, release after next release...)

Multiply this by 100's of servers that an O/S patch may have to be applied to, and fight for outage windows and testing resources in environments that are fully booked for testing of the next LEGISLATIVE release that has to BY LAW go in in anywhere from 24 hours to 3 months away who (as usual) is running behind schedule..

Sounds like they need to be hit with the reality stick.

Judge could bin $325m wage-fixing settlement in Silicon Valley

eldakka

How big is the class?

Whats the potential size of the class here?

Assuming attorneys fees are 33%, that brings the settlement dow to about $213m.

If the class was only 1k people, thats an impressive $213k each they'd get.

But isn't the potential class ALL the IT employess of those companies in Silicon valley? If that was only 10k affected workers, its a lot less but still respectable $21.3k each.

But are there only 10k workers? Whats a more reasonable number for IT employess of Google, Apple, Intel and Adobe in California (or is it just Silicon Valley?) 100k? more ? less? if we take the 100k figure, thats only $2130 each for several years of wage fixing ...

Pozible a bit dodgy?

I just pledged through poizable, however that site seems to have some privacy issues that make me a bit wary of using them:

1) When paying, a message on the payment page states "Pozible does not store your payment information.", yet my pyament details from the only previous transaction I had using Pozible showed up, Payment Name, Country, Phone number, CC number (masked), expiry date. I had the option to edit those details, but I can find nowhere to delete them from the site. So SOMEONE is storing my payment details... I'd like to delete the stored payment information and have it require me to provide those details each time I make a pledge. What do they think it is, eBay where I might make many payments a week rather than once in a blue moon?

2) I didn't initially notice, but Pozible automatically provides my telephone number to the supported project. It is an OPT OUT box on the payment page, whereas providing my email address is a setting I can turn off in my profile, but not for telephone number. I'd much rather give my email than my number to the project. I should be able to disable providing my number as a default setting.

Re: You've done my brain in

"providing any kind of rationisation of why we're here and what the point of us is."

Why do you care? You exist because you do. "I think, therefore I am".

Its up to you to choose what you do with your existence. It's up to you to define the why of your own existance. To party and have fun? To better the world? To better humankind? To save the world from humankind? To kill as many people as you can? To leave a legacy to the world? To spread your genetic makeup (i.e. have kids)? To drift through life aimlessly? To hear voices from a god? Only you can define that for yourself. And only you care, noone else cares why YOU exist.

" Earth as a piece of hardened mucus flying out from some 13 billion year old sneeze, isn't a concept I find very motivating."

If you need science or philosophy to motivate you as to your existance, you don't need a scientist or a philosopher, you need a mirror and a psychologist to find out why you need that.

Burglary and Robbery are 2 different offences.

Burglary is the intent to break into a building without consent with the intent of committing a crime inside (including theft).

Robbery requires both theft and a form of violence or threat of violence used to deprive someone of their property.

4K-ing hell! Will your shiny new Ultra HD TV actually display HD telly?

eldakka

15Mbps streaming over the internet?

Hmm, I pay $60/month for 150GB month quota.

hours/month = (quota (MB) / rate (MB/s))/ seconds in an hour

= (150GB*1000) / (15Mbps/8) / 3600

= 22.22 hours

So I can get 22.22 hours of 4K TV for my $60/month.

Of course, I ALREADY use up all my quota each month on SD TV shows and the odd 720p/1080p movie plus game downloads/patches.

Yeah not gonna happen.

Bay Area plots Googlebus tax after local residents riot

eldakka

So they make a profit...

Quote: "If the city was charging prices equivalent to local Bay Area Rapid Transportation system then that would yield a revenue of around $18.2m per year, compared with the $1.5m or so the City is claiming it will make out of this scheme."

Why yes, they would make $18.2m in revenue, but how much would it cost the city to provide those services for 9.1m rides? $20m? More? So in effect they are making $1.5m profit rather than the loss they'd be making if they ran it themselves.

HTC: Shipping Android updates is harder than you think – here's why

eldakka

at least 2 steps are problems of their own making

1) They don't need to provide their own customized (Sense) UI. They could use the stock android UI and hence skip this step entirely. If they really have a hardon for their (unnecessary) customized UI, make it an optional component and provide it as a separate package. That way they can release a stock version sooner with a Sense UI update later and give customers the choice of stock android or waiting for the Sense UI version to be available.

2) Carrier requirements? huh? This sounds like a chipset provider problem, i.e. provide the correct drivers/firmware for that android version that corresponds to the appropriate GSM/UMTS standards etc for the included chipsets. Any 'carrier specific' customizations like specific software should be the carriers problem and just like with the Sense UI just provide stock android ASAP and provide carrier/UI customizations later.

How about hosting your own website?

And using Facebook et al as a launch page to redirect to your own website?

You can host it yourself. Most NAS boxes from Thecus or QNAP allow you to host a webserver/site on the NAS. Keep it on 24x7 with a xDSL line.

Or use a webhosting service that allows you shell access and the ability to create your own website from top to bottom and just copy the entire website when you move hosting providers.

Using pre-canned web templates or a site builder it's no harder creating your own website than writing a document in word or office.
