Smart TV's as well

Sony is quiet happy to drop support fro BBC iPlayer off its TV's after a few years

Sysadmin paid a month's salary for one day of nothing

a_mu

I took the other way

Having spent the past few years sorting out the &* *& mess on a few projects,

( COBOL and Fortran 4 on my CV was suddenly of use )

and having done to much OT,

On basis that if things did go &*&*& at midnight 1999 / 2000,

it was going to be a monumental &*&*&

Me and some friends took the other option.

We found a small island in the Maldives,

with no internet, very little technology, analog phones to main land,

a small bar, lots of stock, its own diesel generator, and Great diving ,

On basis it would be a great place to be 'stuck' for a month or two.

When we recovered first week in January, we had mixed feelings about how millennium it had all gone so well. ....

Super-slow RAID rebuilds: Gone in a flash?

a_mu

raid on chip ?

It does get one thinking.

Assuming the reliability limit is the flash read /write, then if a raid like controler was on the nvme we could have bigger / ceaper but less reliable flash chips on the drivers .

Cabling horrors unplugged: Reg readers reveal worst nightmares

Co ax cable network and tv studios

I doubt this will be read,

But I'll put it here for posterity.

Oh Yes, used to love the 75 ohm / 50 ohm coax days of Ethernet,

And the great big 25mm diameter yellow cable with the self punching taps to fit ..

But funniest I had was with a TV studio,

yes they had decide to keep costs down and also use what they knew, they would use a coax Ethernet network.

Give them their due, they did start off with colored sleeves on every cable, to distinguish 50 ohm and 75 ohm, ( did not last long ..)

And I disagree with a comment above, 75 ohm and 50 ohm do have different size pins, especially on the big N type connectors. Yes its the plastic that gives the impedance, but they decided to use different pins for some crazy reason...

Then , one night had the dreaded call, time critical, program MUST go out, network un reliable,,,,

Stop gap managed to move the info over on mag tape, to the production machine, that yes , was having un reliable network.

In the light of day, went to look at the problem, all worked well.

that night ,

it went very un reliable again.

So did an all nighter, working through the problem.

changed cables, connectors, cable testers, re configured software, all seemed ok.

then , about 2 in the morning, it all started to work fantastical....

Ah must have been that cable I changed, but it did not feel right..

Next evening, down again... NOT best pleased studio manager...

DONT get on the wrong side of them, ever .....

This time I was ready,

I'd managed to not only borrow / steal a few more bits of kit, TDR , and a big scope, second computer, a test computer, and was all hooked up ready .

Oh yes, it was easy once I looked at the scope and saw the Video waveform on top of the Ethernet signals !!!!

Yes in those days, TV went off around mid night, and was not back on till Tea time,

When studio 5 turned its output to transmission, then hay presto, it injected video on to the Ethernet.

Traced it back to a miss placed video patch into the patch panel above of the ethernet.

Managed to get a nice job out of that, a re wiring so separate cabinets for video and Ethernet

which all had to be done in the day time, luxury.

Knackered Euro server turns Panasonic smart TVs into dumb TVs

a_mu

you only have the TV till 2020 anyway

From 5 years after purchase,

do you think they will still be running the servers ?

do yo think your box will be compatible still ?

think again,

Sony box's, after 5 years can not receive iPlayer et all because Sony do not support them after then.

Will Panasonic be any different ?

welcome to the world of disposable TV's ..

Flash is too fat. A glut of supply means growth is slower and slower

a_mu

cost

We were happy to have a flash drive and a spinning rust drive,

My next step would be to look at getting rid of the rotating rust drive,

and just having flash, but that price is still way to much,

if I have to have two drives, the flash of 250 G is perfectly fine,

any bigger is too much to be worth while, till it gets to at least 1 TB , preferably 3..

Come in Internet Explorers, your time is up. Or not. Up to you

a_mu

microsoft being popular

Were our own worst enemies.

IE has been so none standard, but popular that we have all written lots of get arounds for its problems.

But those get arounds just don't work on standard complaint browsers.

But were lazy, under time pressure, and only coded for the most likely browser.

now we all have code that only runs in versions of IE ,

and no money to change code base / big risk.

As for using other browsers,

well , I don't know about your company, but the big ones I see fix the code set, don't allow people to update software or run what they want to, so users can't change.

greatest thought I heard from a manager was "why can't we 'JUST' run the version of IE we want inside a new version of IE", sort of virtual mode ! !!!!

Hapless Virgin Media customers face ongoing email block woes

The hassle as a end user of virgin is

now all gone ,

so I moved email providers and all happy again, but come on virgin,

And so far only a few percent of emails moved

So far, its only the blueyonder and ntlworld accounts that have been moved to the new virgin server.

Just think whats going to happen when the much larger number of virginmedia accounts are moved,

Dont forward to ntlworld.com

DO NOT forward to NTLWORD.com email address's

The virgin system now filters most forwarded mails , and just blocks them .

no spam no warning, just bounced.

Now once upon a time the ntlworld mail just worked, then came virgin with google, and it was OK, now google have dropped virgin, and virgin managment just seem not to have this under control.

My daughters phone suffered a few problems, so it was taken back to the shop, who lent her a unit whilst hers was being repaired.

she used the phone for a few days, then returned it to shop when her phone returned.

Virgin Media's SPAM-AGEDDON 'fix' silences mailboxes

a_mu

Virgin email

Yes, the virgin change over seems to have been an on going disaster for many weeks.

The forums now have almost as many complaints about SPF , forwarding and emails going missing than complaints about speed and throttling, and thats saying something.

For a week or so, there was a valiant effort by support on the forums to provide a patch, but for the last week, the admins have been silent.

Many of us have been with NTL world for a long time. in my case almost 20 years, and the used to provided unlimited email accounts.

OK, yes I have my own domain, but that all gets forwarded to my ISP, well it used to till virgin changed and now bounce most mails that come in from a forwarding service.

and the trouble is, unlike spam that gets put to one side, so you can at least find a missing email, ones that Virgin bounce are lost with out trace, nor notice to the user that they have gone !

Personally I think Virgin just want to dump email and become a pure ISP, much less support needed so cheaper.

wonder what happened to all those that used to run ntlworlds email before virgin out sourced them to gmail,

come on back please.

Scrapheap challenge: How Amazon and Google are dumbing down the gogglebox

Yes ,

We have a bunch of sony TV's,

as you say no updates for a few years,

provided they still get iPlayer then we will be ok for a while,

Yes,

if you purchase a device to receive a service, then one would expect to receive a service for the life of that device.

TV's are not computers,

may be we should all look at TV's as being individual units.

The monitor part, a sound bar and a box to receive the TV !

thats what my TV's are turning into

White Stork mates with ISS, delivers bundles of resupply joy

Just a thought,

Why take up dehydrated food when you then have to take up water to re hydrate it.

As the ISS recycles most of its water, take up some nice food, with water in it.

food A mass = mass water in food A plus dry mass of food A.

that was your conclusion wasn't it.

Why the BBC is stuffing free Micro:bit computers into schoolkids' satchels

a_mu

October ?

sounds like its too late for this year to me.

Out in October,

The schools are already planning / planed what computing they are offering next year.

I would hope the teachers were familiar with the thing before teaching it,

Say a week of practice before they can teach with it.

and the material, another week or two to plan it into the curriculum,

I dont know about your teachers, but at the start of the year ours are quite busy,with the new class.

they can't take a week or so out to learn a completely new product.

The BBC should have the teaching material with the teachers now,along with a unit to try out

Remember the BBC micro, all those great TV programs,

I seem to remember the programs came out before the schools had micros

Your servers are underwater? Chill OUT, baby – liquid's cool

a_mu

capacitors et all

Well

I've designed boards that are liquid cooled,

all the boards are in a big box which is filled with a pink silicon type liquid, and the box closed.

Yes there is room for expansion, and the walls of the box have water flowing through them to conduct the heat away.

Biggest problems,

any oscillators / crystals need special attention

the impedance of the tracks on the surface of the board are different to being in air.

( but as there is no dust / skin cell build up over time, at least its possible to calculate )

Capacitors not a problem, if you use the right ones.

The most common capacitor is a ceramic, and most of them are fine,

just check.

When it comes to analog / rf, then things are a little more difficult, the fluid does tend to kill them,

but digital is just fine.

But

it does make the thing REAL heavy

and once a board has been in the fluid for long, its impossible to solder to it ever again,

the fluid just can't be cleaned off sufficiently well to make a good joint,

For 'fun' one time, we ran one of the boards in liquid nitrogen,

now that was cool, but we dare not seal the box !!!

Will it catch on at home, I don't think so, but some of these real small PC's that fit in the hand might be interesting in a sealed box full of liquid.

Elon Musk's Tesla set to unveil home storage battery

a_mu

FIT

Ok,

I've been looking at these from a few suppliers ,

I have a PV system,

and what do I do with extra energy, export it , or use it to heat .

the house base load is around 300 watts ,

so a battery of 'only' 14 KWh would be fine to cover my background needs assuming 50 % efficiency in the DC:AC,

And I generate that each day or more 9 months of the year.

For reference a standard 200 Amp H car battery is around 2 KWh though I'd not use them,

The batteries in the Teslar are 60KWh if I remember, so more then enough to get me off grid most of the

Listen up, AT&T, this could be YOU NEXT: $40m sting for throttling 'unlimited' mobile data

a_mu

Re: and in the UK ?

whats the difference to the user in 'variable contention' and variable data rate / throttling ?

So I pay for 60 , but I get 30 , due to contention,

or I pay for 60 and get 60, and after a time, the data is throttled .

As far as I see, both limit the amount of data in any 24 hour period !

Ok one might be more severe in practice in its implementation than the other,

but to the user they are both the same.

so we 'save' 2% by having smart meters.

i.e. we use less electricity and gas.

The companies who supply have a fixed infer structure and overhead costs,

so if they sell less they make less.

it was possible in 1970,

tap at the repeater, where things have to go back to electrical, not optical.

To tap a fiber is also easy, just bend it and put another fiber along side it,

you only need a few photons, but more difficult underwater !

A modified repeater would also be nice. use the dark fibers in the bundle to take a copy of another ,

its all too easy , and the gains too high for it not to happen.

Boffin fights fire with EXPLOSIVES instead of water

Re: Hang on...

dont think so.

They spent a long time using cat crawlers to pull out as much loose metal work as possible,

then they used the explosives to stave the fire of the air, and blow it out.

they did not want loose metal flying around and re starting the fire, let alone hitting some one.

worry was , at the end of the vid, one could see the flame from the det cord.

that red stuff they use on forest fires,

then yo have the combined effect of flame retardant, cooling of the water, and speed of the shoot blowing the flame out ?

Sad the reason we HAVE to go for the fraking is because we have not invested over the decades in new generation capacity, and the only thing that can now be built in time is gas fired turbines !

now its happened, whats the answer !

basic for today

once upon a time,

no mater what computer I was on, I could knock up a basic bit of basic to do something I wanted done,

then the 80's came along, and basic was BAD

so now I have to know and use, TCL, Python, VBasic, C in all its forms, Jscript, and a few more,

and I'm a hardware developer just trying to use the computer..

Yes I have a fond heart for Basic, like all languages , it can be used worng,

one place I worked at, used a fortran 77 program they had written to word process !

and another has a cobol based spread sheet like program,

but basic, its still in my heart and soul,

youngsters today just don't learn to program, but then, neither did we, we just had fun making things bleep and pixels flash, that doesn't do it for the kids now days.

multi level storage optoins

So

what we need is an automatic multi level storage system, lets call it a cache.

A lot of the stuff on my discs, is write once , read many,

very little is write multiple / read multiple,

so 'just' need some gear that can move data around as needed !

Comprehensive security in the home

a_mu

why one solution

Out of interest,

the 'problem' I found one time was that one particular security package had a hole, and all the kids pc's got infected at once. Try to fix that one,

so I now put different anti systems on different machines,

for instance I currently use avast and avg for anti virus at home,

it was surprising what one will find that the other won't ,

same with anti male ware,

Add to that the android tablets, the Nintendo's and tv;s with web access et all, and security is interesting.

as for parent control,

impossible,

if my kids are anything like I was at 12, then I will not be able to control what they do

so I 'just' have a snooper on the gateway, makes log of all sites visited,

lets hope they don't find vpn too soon,
