a) Majority of XP systems not regularly patched anyway, so makes not much difference.
b) Many vulnerabilities are blocked by firewall/router
c) Most bad stuff is now from Internet, not shared disks, people click and install it. Or it can be mitigated by NoScript etc (Which I run on Linux as malware isn't the only issue it solves).
d) People with Win10 and 3rd party AV can be as easily infected if clueless and keep clicking on OK, installing toolbars, fake codecs, opening attachments, etc.
ActiveX in a browser. A stupid idea, in an ideal world who ever signed off that in MS should be in prison. Might as well send all kids past puberty to a brothel for every birthday party.
Probably more stuff runs XP than Win 10 as nearly all Win10 is on the Internet (it's broken otherwise) and some computer users and applications can't get, or don't want or must not have Internet. Meanwhile some people telling their XP Workstation and Win 2003 server that it's a POS terminal and getting Server 2003 and XP patches for free.
Relying on the IP address to validate anything is nuts.
Paying bogus invoices is incompetence.
No native voice on 4G. 3G and 2G voice is native, early data modems simply used the voice modulation, hence 245kbps on 3G and 14.4kbps on GSM. HSPA on 3G adds non-voice modulation modes to the CDMA hopping carrier to increase data rate, depending on link S/N. GSM EDGE is also a trick using different modulation to original GSM to get 200Kbps + There is a version of GSM (not used) for data only called ERMES+ that can do 2.4Mbps and native IP only (no voice). Superior to 3G HSPA as there is no cell breathing and speed is consistent. But bad for marketing as can't compete on peak speed.
3G has no native IP, IP is native on 4G
3G is a wider band version of CDMA-1, typically 5MHz CDMA coded channels. 4G (on downlink at least) uses COFDM or even COFDMA (loads of separate carriers, in 1MHz, 2MMHz, 5MHz, 10MHz or 20MHz channels. GSM uses a 0.2MHz carrier. CDMA 1.25MHz, or 3G 5MHz, is a single carrier frequency hopping in a known pseudo random fashion. Each link is different key. If all keys are used up, then the data is multiplexed, voice and data are different for 3G and HSPA version of 3G.)
Flash-OFDM, Wimax and LTE are 4G systems.
WiFi can be CDMA or COFDM depending on version.
There are real 4G specs, though the important ones for 4G mobile are all LTE, which is certainly NOT at tweaked 3G, it's as different as 3G is from GSM (2G). The 3G is however based on USA 2G (CDMA-1), I guess Qualcomm wanted more money.
" IPv6 was designed from the ground up to cope with mobile devices."
I've never ever seen that claimed before. Other than the addressing size and giving the same IMEI the same v6 IP every time. (Which might be a bad idea for privacy!)
"the need to maintain a static IP address while moving from mast to mast and (potentially) roaming between different subnets."
That's a completely separate issue. It's still not very reliable. Switching between 3G,4G and WiFi without losing a session is really hard. It's possible and IPv6 is nothing to do with it. Switching between mobile 4G sites with IPv4 works fine, was testing it in 2007.
3G has "voice HD". It has a choice of codecs. 4G can't use some of the 3G and 2G codecs as they are less than optimal for TCP/IP UDP type networks. VOIP needs codecs optimised for TCP/IP unless you know the latency and packet loss is very low, even then the native "wireless" codecs have wasteful frame sizes for IP traffic
You'd care if other people's voice calls was only carried on 4G. The data speeds might be 1/4 for you.
No-one is "going for 5G" already. It's still an ill defined concept, possibly more about integrating infrastructure. There is no 5G standard yet, nor any 5G base stations or software or hardware.
No, IPv6 mainly addresses the addressing issues. It does have some other "fixes", but still inherently not good for Wireless. If it was, then Satellite systems would use it natively on the links (nearly 90,000km each way, ground station to user.), they don't.
Mobile / Wireless needs a protocol designed for massively variable speed, packet loss and latency, which can vary from excellent to really bad in minutes for a given link. Also the number of user connections per sector can vary from 1 (20Mbps) to 20+ (0.12Mbps) during a transaction without the addition of weather, movement, interference (even from other cells) or whatever affecting the speed, latency and packet loss. IPv6 doesn't make a huge improvement over IPv4 for that scenario. Also Mobile has the philosophy that individual users get all of the bandwidth available, rather than throttling back power (reducing inter cell interference and increasing battery life) when 1 or 2 users compared to 5 users in a sector. It's pretty garbage anyway for more than 10+ serious users of data (c.f. 3G where about 100 native voice calls are possible).
4G is really really inefficient for voice calls compared to 2G and 3G native voice frames as it's carried as VOIP using TCP/IP to setup and control, then UDP streams. Hence most operators with 4G & 3G make your voice calls use 3G or even 2G!
" optimized for the massively varied use cases of the next mobile generation, for cloud services, and for virtualization and software-defined networking (SDN)."
Only wireless is different from point of view of TCP/IP stack and protocol compared to the others.
"Cloud Services" = Remotely connected servers, nothing new here.
"Virtualization" is irrelevant.
" software-defined networking (SDN)" isn't really about TCP/IP at all. It's infrastructure management.
Radio unlike cable*, fibre and in house networking suffers from variable packet loss (other fixed cable/optical links have almost none to zero) which can be high. Wireless has unpredictable variable latency and speed too. The other technologies at the link level are pretty much fixed latency and speed. So TCP/IP is really poor for wireless, especially outdoor wireless like mobile. The ultimate "wireless" is satellite. It doesn't bother with TCP/IP at all. Best to imagine each end of two way link is a pair of proxy servers with a special protocol between them. That's why a VPN is garbage performance on Satellite unless the satellite ISP has your VPN endpoint in your modem and recreating the VPN at their Groundstation.
This is why 4G stuck with TCP/IP, though really a poor solution for mobile, as without being more clever than the Satellite modem folks, lots would be broken.
So this is really ONLY about mobile and how to have not TCP/IP over the wireless transparently to all existing traffic. Look at IP V6. Is the end user or average business going to change to an alternative to TCP/IP?
Anyone today can do their own design of TCP/IP implementation on their OS (virtualised, cloudy or not) as long as to the external network port that it meets the spec!
[* DSL, VDSL etc and other schemes over Cat 3 (phone wires) is more like Radio than cable or fibre. Unlike actual outdoor Mobile, the latency and link speed is constant for a given pair of wires, but the packet loss / interference issues can be like WiFi or Mobile. A powerline Ethernet adaptor or electric fence can disrupt DSL]
Future Alternatives: Paint Shop pro had promise at Ver 7.
Corel bought it and messed it up.
Gimp isn't as bad as it used to be, but I'm going to see can I install PSP7 on WINE!
There does seem to be some alternative to Adobe Ransomeware for some people.
Daft ejits if they think a mobile connection can ever replace local apps and local music and local photo taking and local note writing. Even Chromebook backtracked on that.
I don't want a cloudy phone. I don't want to rent services, experience out of coverage errors and have a data bill. Actually I'd like all the Google "cloudy" services such as Playstore and Location to be able to be disabled, manual or automatic/startup like on Windows or Linux.
I'm quite happy with USB storage mode too, to put stuff on/off from laptop.
Why is Facebook such a piece of uselessness?
People tend to only consume more of the same. People will be aided in being narrow in taste and outlook, prejudices reinforced.
The exact opposite of BBC Charter.
Internet connected toilets? IoT
Vacuum cleaners, wood burning stoves, coal bunkers, mirrors, beds, floors ...
The UK is 20x bigger market. So FTA Irish TV over UK would make TV for IRISH viewer prohibitively expensive for bought in content OR locally made. Any content that UK broadcasters have rights for would them be unavailable at ANY price to Irish broadcasters
Also Ka-Sat has no crippling EPG costs.
Sky ought to be paying RTE etc for the 28.2 Encrypted content. They get it free which makes Sky Ireland competitive.
Sky Encryption, Sky EPG, Freesat EPG, 28.2 Carriage. EACH of those alone is more expensive than Ka-Sat, which RTE uses as a transmitter site backup feed. Sky was charging RTE a fortune for the viewing cards for transmitter sites! So Ka-Sat, which is fill in for people pay TV licence in IRELAND, is essentially free.
The shame is that carriage on Ka-Sat is optional. So TV3 and I think UTV Ireland are not on it as the small cost is more than any additional revenue for 1% to 2% of viewers.
There was originally the Solas Card. The money paid to sky was enormous. Then when BBC, ITV and C4 closed the scheme, Sky had "Freesat from Sky" card for small charge. Puppy dog trojan advertising to get full sub.
Tara went bust on Sky because of the costs of Sky EPG and Encryption. Sky provides this free in Ireland for RTE etc as otherwise Sky PayTv can't compete with Cable (UPC/Virgin and now Eir as well as Crossey). Sky would charge RTE more per channel for UK EPG and Encryption so much that TV licence cost would double!
a) Know they can't get a sub.
b) in UK your dish only gets UK content unless it's multifeed or you have a 2nd one, Sky almost satellite Pay TV monopoly.
c) Newer satellites have narrower spots so pan Western Europe is now needing a very big multifeed or motor dish, or in case of Ka Sat tiny spots and frequency re-use, out of area is impossible even if you have a 4.8m dish.
Visa are nuts if they are serious about bitcoin.
IBAN will be the basis of a sensible Universal Electronic Currency, not PayPal or Bitcoin. The only current obstacle is the USA.
One does wonder if BitCoin is a clever ponzi scheme and if someone "engineered" the mad Tulip "investment" bubble ... The name surely is a deliberate joke?
At the peak of tulip mania, in March 1637, some single tulip bulbs sold for more than 10 times the annual income of a skilled craftsman. It is generally considered the first recorded speculative bubble (or economic bubble), although some researchers have noted that the Kipper- und Wipperzeit episode in 1619–22, a Europe-wide chain of debasement of the metal content of coins to fund warfare, featured mania-like similarities to a bubble. The term "tulip mania" is now often used metaphorically to refer to any large economic bubble (when asset prices deviate from intrinsic values).
The 1637 event was popularized in 1841 by the book Extraordinary Popular Delusions and the Madness of Crowds, written by British journalist Charles Mackay. According to Mackay, at one point 12 acres (5 ha) of land were offered for a Semper augustus bulb. Mackay claims that many such investors were ruined by the fall in prices, and Dutch commerce suffered a severe shock. Although Mackay's book is a classic, his account is contested. Many modern scholars feel that the mania was not as extraordinary as Mackay described and argue that not enough price data are available to prove that a tulip bulb bubble actually occurred.
Wikipedia, may contain nuts.
" Google Glass got the same treatment, and you know what? That's still not dead, either."
They lost sight of their mission.
It's only fast for a very limited class of problem. We still are not sure what is in the box. It's not an actual quantum computer, but obviously different to a conventional CPU, GPU or possibly different to a FPGA implemented specialist processor.
Hence Google calling it "Quantum Annealing"
The 5m is optimistic, with RF quiet environment and large direction receiver, unless this is a perpetual motion machine breaking the laws of physics.
A 2.5cm to 20cm range is more realistic. It doesn't matter how little power the chip uses. Even if it has a BIG capacitor and only transmits in 1:100 duty cycle low data rate bursts.
You can't fit any kind of sensible WiFi aerial on a 2mm x 2mm chip either.
This is no different to an RFID chip, simply sending temperature rather than an ID Tiny range unless less specialist kit to power and talk to it and listen to it. "Smart Building" uses are fantasy.
Reminds me of some of the old PRE Victorian dreadnaughts and ironclads.
I'd not like to be in it if it's hit broadsides by a wave!
Unless there are cats.
You know cats are NUDE under the fur?
"I think you'll find that the reason everyone moved their embassies to Tel Aviv is, officially at least, that they consider Tel Aviv"
That would be IDENTICAL to people outside USA deciding New York is USA Capital not Washington.
You may hate it, but UN has ruled Israel has a right to exist, and the Newer part of Jerusalem has never been part of any State than Israel. Only Britain and Pakistan recognised the illegal Jordanian annexation of East Jerusalem / Old City and the "West Bank" (Occupation 1948 to 1967).
Syria doesn't recognise Jerusalem as anyone's capital as they regard Israel, Lebanon, West Bank, part of Gaza and Jordan as "missing" Syrian territory.
Before 1948 there was the British Palestine Mandate, most of which today is Jordan.
Before that the area was a part of the Syrian provence of Ottoman Empire.
Nations can pick ANYWHERE in their Territory as Capital. Only the Old City is disputed and claimed by the Palestinians. That isn't recognised by UN.
It would have been interesting if it claimed Jerusalem is capital of Jordan or Palestine. It's never been the actual capital of anywhere other than Israel, though Jordan illegally occupied the "old city" part from 1948 to 1967.
It's true that due to Arab and Moslem threats everyone moved their Embassies to Tel Aviv, but it's not the capital.
However Wikidata sounds bonkers.
People do business with Qualcomm because there sometimes is no alternative. Though they make stuff, they annoy everyone in the industry with their lack of commitment to products. They want to make all their income from licensing, IP etc.
SQL wasn't a Microsoft product. They bought in Sybase.
They DID write GUI Word and GUI Excel -- Ironically first of all for Mac
Visio, Powerpoint bought in. Access was and is pointless.
MS DOS bought in
Win NT piggybacked on OS/2 and VMS with the Win 3.x shell (copied like Mac from Xerox).
CE was a cut down NT.
Like Google and Apple, there are very few successful from scratch MS products. Or much real innovation.
Or IDC would be saying there will be ZERO new Windows Mobile phones in 2019.
It's a MYTH.
There ARE brilliant women.
Hedy Lamarr's name was added to a US patent for frequency hopping as a joke. It wasn't even a real US invention but a "stolen" idea.
Possibly the only slight change was using a piano roll type card to program the frequencies at a very low chip rate
The idea was from a German demo. It's not much related to the first commercially viable spread spectrum systems (military in around 1970s) or any since.
The US Navy was uninterested as it wasn't practical and at most Hedy Lamarr's input was telling the real writer of the US patent about the German demo.
Lead free solder dramatically has increased failure rate. Thus INCREASING landfill. The health and environment impact, if electronics is built to last and then recycled is negligible. The prohibition doesn't apply to Aerospace/Military and some watches.
Also gold is unsuitable for consumer connections. Any damp and nearby tin is attacked. Gold should only be used with gold, and if not regularly unplugged. It's not even the best conductor, just corrosion free and pretty, though causes electro-galvanic corrosion in many other metals.
Fan failures over the last 20 years have been a massive source of PSU, CPU and Graphics card failures.
While ceramic and plastic dielectric capacitors are hugely better than 1950s paper capacitors, the Electrolytics are a disaster, modern ones seem to be too small and in places with more heat than a valve radio (they put the caps away from hot bits). I think modern electrolytics are 1000s of times less reliable than 1950s ones.
I think it's too flat?
Certainly no very high mountains, so too much atmosphere.
Could be worse. Vtech might bring out a doll. Maybe Facebook (Daddy loves Max?) or even Google. I can't quite imagine Apple (too cheap a market*) or Microsoft (Windows monicker seems hard to apply).
Is the Sindy name available to buy?
[*I think these sell for US$75, they aren't listed here yet]
Wrong, it's BOTH.
As I have banged on in these pages many times:
1) We see the same old stupid flaws
2) We see a huge proliferation in poor languages, though good programmers can write good programs in them.
3) We see learning a language confused with learning programming (see points 1 & 2)/
"Next up, Steve Balmer praises Linux"
He sorta did, except Android apps only run on Linux on an Android phone, but not when on a windows phone or Blackberry (excluding recent one).
I think standard Pascal was always pretty useless as real world language. Borland Turbo Pascal was almost Modula-2. It was good at the time (1970s to 1980s) as an introduction. FAR better than BASIC, which was cut down ForTran intended to be a stepping stone to Fortran.
BASIC was stupid by 1980. I didn't use it again until VB6, which allowed a totally different style of Programming. Other than teaching and derivatives like Turbo Pascal, Pascal was never a very viable real world implementation language. Modula-2, Ada widely available from 1983 and C++ from 1986 all superior to pascal. I started C++ programming in 1987.
Most modern programmers TOTALLY fail on the difference between learning a programming language and learning to program. Or the difference between a language like Scratch (only intended for teaching concepts) and Python, which assumes you already are an expert programmer.
A language that might be brilliant for a particular real world class of implementations might be useless for teaching programming. Unfortunately only a small percentage of programmers concentrate on design rather than debugging, I BLAME MANAGERS! WHY ARE YOU NOT WRITING CODE!!!!. Most people have concentrated on learning the language and libraries, but NEVER EVER have learnt programming and design properly. Otherwise why to we STILL see the same old bugs and vulnerabilities that are totally avoidable? (Bad management is a lot of it). Cross Site Scripting, Array Bound Violations and SQL injection. A lack of defensive programming. Looking a GNU / LInux source, Web site source etc we are going backwards in quality from the late 1980s in Web and PC software compared to some Telecomms and Industrial then.
An FPGA based board for Oberon, though expensive at $170 is to be welcomed as at least a fresh approach rather than "yet another linux" board. I have Pi, I am typing this on Linux Mint. I have two Linux servers and I supported MS Oses for 20 years. In contrast there seems to be a load of script kiddie fan boys knocking this because it's more expensive than a Pi and only does Oberon, who really don't see the big picture!
Python is FINE for anyone that has learnt to program.
It's total rubbish for TEACHING programming. Scratch is HUGELY better for that.
If the aim is to learn, then Pi + Scratch is a good start for kids 10+ years
If you are 15+ and want to really learn to program AND write real programs instead of hacked scripts, then Oberon board is great. Previously you had to dedicate (or dual boot) a laptop to it.
Modula-2 + Lilith is the early ancestor of this.
(I used Modula-2 from 1983 to 1996 and wrote an entire platform game which ran from DOS and no assembler in 520K. Virtual device drivers for different graphics cards automatically loaded.)
PASCAL to Modula-2 is like 1978 MS Basic and VB6.
Oberon much more advanced
Pascal was only meant to be a language to learn Programming, not to learn Pascal.
Colleges destroyed the development and deploying of Modula-2 in the 1980s to 1990s by simply teaching Modula-2 as if it was pascal. Modula-2 didn't explicitly have C++ class syntax, you could use opaque modules, separate compilation, typed procedures passed as parameters.
It had parallelism and multicore support as part of the language via co-routines and mutexes.
Compilers in 1990s could do much compile time array bound checking foreign to C or C++
Types even STRONGER than Pascal, so anonymous Array types are not compatible.
But MAGIC types for device drivers (Array of Byte) with ability within a procedure to call to find array bounds!
Oberon is MUCH better.
Sadly the rest of the world is mostly stuck at 1976 levels of programming and I've lost count of how many C++ projects that simply "reused objects" (or even no objects) and otherwise no lessons from Strustrupp and C++, practically compilable with a C compiler.
It's a pity it doesn't have HDMI as well as VGA and isn't half the price. It's a brilliant idea.
Scratch on Rasberry Pi allows teaching programming. Python on Pi to turn LEDS on / off is worse than JAL, BASIC or C on a bare metal 18Fxxx family PIC with a USB port to connect to PC or Tablet.
VV06 countdown resumed for launch scheduled on 3 December 2015
Checks carried out for ESA’s LISA Pathfinder mission have provided satisfactory results.
Arianespace and ESA have therefore decided to resume preparation operations for VV06 for a launch scheduled on 3 December 2015 at exactly:
01:04:00 a.m. (local time in French Guiana),
11:04:00 p.m. (Washington DC time), on 2 December,
04:04:00 a.m. (UTC),
05:04:00 a.m. (Paris time).
video on arianespace.tv
Phase differences vs distance if it's a wave will give a frequency signal. So if the two detectors are at a suitable distance apart compared to wavelength.
Maybe delayed ...
"During the final step of VV06 launch campaign, a technical issue on the Vega launch vehicle required additional analysis. The launch initially scheduled for December 2, 2015 is postponed.
ESA’s LISA Pathfinder spacecraft is in stable and safe conditions and the launcher teams are currently working on this technical issue.
A review of the results will take place tomorrow [2nd], leading to a decision for a possible launch on December 3."
I want Thunderbird to be supported. OTH, I wish there was a decent fork of Firefox, because Mozilla big time have lost the plot. Totally annoying & pointless GUI changes that make it HARDER to use. Stupidity like built in PDF viewing. They aren't even properly maintaining, never mind developing Firefox properly. They have made GUI on Thunderbird worse and not added calendar/meetings widget in a way to kill horrid evil outlook.
They put a nasty wizard for new email accounts which makes it HARDER to add extra POP mailboxes.
Both products are going backwards.
I used Eudora before I moved to Thunderbird very many years ago.
Who is likely to take on Thunderbird and actually improve the GUI and add meetings/calendar and fix the horrid new account wizard to make it optional rather than add the latest GUI fashions?
Well ... I'm surprised.
wifi microcontroller module
Maybe it's the same one in IoT kettles and coffee makers.
Maybe ... Though I find Notepad++ on WINE on Linux good (I've read the explanation as to why open source NPP has no native Linux version despite being based on a Linux editor). I can't find any native linux editor* as flexible and useful for any arbitrary scripting, compiled language or even writing novels. Easy to add back end compilers, SVN/GIT, plugins, new languages (even roll your own), customisation, speed, powerful regex search/replace on doc, open files, matching files, subdirectories etc..
It seems a misleading name and less "visual" than 2000 era so called "Visual C".
No interest in those.
Can it be used to develop for Android, Linux, Embedded Microprocessors?
Is it more than code editor and project file manager? What is advantage over Eclipse, Netbeans, Sharp Develop, Notepad++ etc?
How is it different to the VS for VB6, or the newer Visual Studios for VB.net and C# ?
When is it likely to leave Beta?
I didn't get much out this review.
Icon as I'm obviously clueless as to why I'd download and install this on Linux
