OK brainiacs, we've got an IT cold case for you: Fatal disk errors on an Amiga 4000 with 600MB external SCSI unless the clock app is... just so

toejam13

DMA issues with the A3000 as well

The Amiga 3000 included an onboard Western Digital 33C93 SCSI controller chip as opposed to the Amiga 4000's onboard IDE controller. Problem was that the 33C93 included a DMA bug that could lock up the machine under the right circumstances. I rarely triggered it while running AmigaOS, but I hit it all the time running NetBSD.

I worked around the problem by installing a Zorro II SCSI card, but it was terribly slow since ZII DMA was disabled on the ZIII bus. Eventually WD released a bugfixed 33C93A chip that resolved the corruption problem, but I had moved on to using an A4000 by that point.

I was lucky in that my Amiga 4000 included an r11 Buster, so eventually I fitted it with a DKB 4091. I also tried adding an A3640 processor card, but apparently it was too much for the system and it completely fried after a couple of hours.

So I pulled out my old A3000 and then transferred the r11 Buster, 4091, and Cybervision 64 to it. It lived on a few more years mostly running Shapeshifter (Mac emulator) running System 7.

Freed from the office, home workers roam sunlit uplands of IPv6... 2 metres apart

Re: Perhaps (probably?) mobile users

Not just carved up, but done so with a heaping side of static configurations. My employer has well over 20,000 servers (physicals and VMs) in five data centers, all of which have static IPv4 addresses. Those addresses are hard-coded in DNS, firewall rules, load-balancer pools, monitoring groups, and so on.

We now have IPv6 configured on the vast majority of network devices, so the current plan is to run hybrid IPv4 & IPv6 from clients to our forward facing load-balancer devices, which will then deal with all of the translating. They don't care if a server pool is all IPv4, IPv6, or a mix, so we can slowly migrate the back-end during the next scheduled tech refresh. We can also kick the can down the road if problems arise. But since tech refreshes are about 4 years apart, that may be a while.

Re: Looking through the wrong end of the telescope

Supposedly the EU has filed a dispute with the WTO regarding forced technology transfers and joint ventures, so the issue is at least being investigated somewhere within the organization.

That said, my understanding is that the USTR was unable to bring a case to the WTO because so few companies were willing to publicly cooperate with the investigation. Any company that accused China of these behaviors feared swift and severe retaliation. It wasn't an unfounded fear based off of past trade tensions and dealings with companies that outright refused JVs and FTTs.

It'll be interesting to see if the US can link their case with the one from the EU. I could see a WTO arbitrator channeling their inner Vogon, spanking the US for failing to use proper WTO channels and going at it alone instead of letting the WTO grind on the issue for a decade before finding some technicality to reject the complaint.

Falling NAND prices to drive NVMe SSD uptake, say industry watchers

Re: SATA SSDs

Don't forget that some of those motherboard solutions can be rather limiting. On my Haswell i7 box, the onboard NVMe port was only PCIe 2.0 x2, so I had to pick up an PCIe card that could run the drive at PCIe 3.0 x4. Had that not been an option, NVMe would have been a waste.

America embraced CDMA?

FTA: "It wasn't that long ago that America decided not to embrace the global GSM standard and opted to go for CDMA instead"

That's not entirely true. Prior to 4G, American carriers never embraced a single wireless standard. In the 2G days, some adopted Qualcomm's CDMA standard, NexTel adopted Motorola's iDEN, and the rest eventually adopted GSM.

AT&T Mobility was actually a huge driver of GSM because of its partnership with BT and founding membership in what eventually became the 3GPP. After they dumped their D-AMPS kit for GSM, most other North American carriers using D-AMPS did the same.

Sprint briefly flirted with WiMAX, but eventually every American carrier adopted LTE for 4G.

Samsung Galaxy A9: Mid-range bruiser that takes the fight to Huawei

toejam13

Sorry, no A-series for the States

Samsung refuses to officially sell the Galaxy A-series in the USA, pushing people to purchase the more expensive S-series or much cheaper J-series phones instead. Buying a previous gen S-series phone could get you a phone closer to the price point of an A7 or A9, but then you're stuck with an older model that will probably never see another OS upgrade.

Samsung does sell the A-series in Canada, and those models support most of the LTE bands used in the US, but if you purchase one off the gray market, good luck getting WiFi calling to work with your carrier or getting Samsung to honor the manufacturer's warranty. Some people have even reported issues getting their carrier to enable voice-over-LTE with "unsupported" phone models, so I suspect those phones will struggle with voice calls when legacy 2G/3G bands are converted to 5G in the near future.

IPv6: It's only NAT-ural that network nerds are dragging their feet...

toejam13

Re: Obvious need for..

> if you want widespread adoption of a new technology it needs to be backwards compatible, because people. As a prior example see the roll-out of colour television, where the signal was backwards compatible with black and white sets...

For most 525-line and 625-line systems, backwards compatibility wasn't difficult. In those systems, adding color was nothing more than adding supplemental information within the payload. Almost everything else about the broadcast remained the same. For terrestrial broadcasts, you also had the benefit of there being no intermediary devices between the transmitter and receiver that had to be color-aware.

But for a backwards compatible IPv6 system, things become very difficult because you need end-to-end awareness for it to work. What were to happen if the extra address length was added as an IPv4 header option and it passed across a router that wasn't IPv6-aware? That router could strip the information, resulting in a misdirected packet.

Sometimes, passive backwards compatibility just isn't possible. Just look at the "dual-stack" period that Ireland and the UK had while it supported both the newer UHF 625-line and older VHF 405-line systems. Between the incompatible frequencies, channel width, and timing, the only way to bridge the two standards was through the use of translator stations that converted 625-line content down to 405-line signals for older televisions.

In the case of IPv6, proxies and network address translation devices act as a equivalent to those translator stations. Sure, it adds complexity in some ways, but it also simplifies things in other ways.

toejam13

Re: "the world is clinging stubbornly to IPv4"

> Their solution was to just drop IPv4 altogether and only have a bunch of edge servers speak dual-stack.

The large finance company I work for is going down the same road. We had some struggles during the last corporate merger due to significant overlap in RFC 1918 network ranges. We also have to use source and destination masquerading on our private tunnels running to third parties due to similar range overlap.

Our long term goal is to have our perimeter firewalls and load-balancers running dual-stack so they can perform NAT-4to6, while having everything else behind them running native IPv6.

Besides eliminating future potential merger issues, the company is motivated to complete this migration so that they can sell their sizable holding of IPv4 addresses while they still have significant value.

Leaked pics: Motorola to add 'unpatriotic' 5G to 4G phones with magnets

Re: I dont really understand why i need 5g at all

> I believe there are considerations in high density areas - 5G is shorter ranged using more, smaller base-stations, and these will have less users on each one.

That depends on the frequency being used. The new 5G NR protocol includes a number of new channels above 2 GHz that will be used for micro-cells and pico-cells. But it also supports all of the channels in use today. It isn't unlike how UMTS/HSPA and LTE each gained access to channels that were either unused or experimental during the previous generation.

Expect to see carriers reallocate most, if not all, of their older 2G and 3G channels for 5G in the next few years. So anything from 450 MHz to 60 GHz could be used.

> Other than that, I agree that 4G is fast enough for the foreseeable future

While you may not need the extra bandwidth, one major advantage to shorter transmission times is that radios can go back to sleep sooner, which helps with power management.

Also, the new 5G NR protocol is designed to help cellular carriers better compete with traditional WISPs. It offers lower latency than LTE, better channel/tower aggregation support, and the possibility of switching from FDD to TDD, which allows the network to better handle changing asynchronous loads.

Re: Data smugglers, look at the back of the PC

Unlikely. Instead of relying on the honor system, they'll probably roll out an enforcement agent to all of their systems (if they haven't already). Such an agent would probably block any untrusted drive, not just hot-swappable ones.

My employer uses software like this. Users are authenticated via a bootloader before either Windows or MacOS starts. The rest of the drive is encrypted. If there are any unencrypted drives or partitions, they are never allowed to mount.

If I attach a removable USB, Firewire, or eSATA drive, or if I insert a disc into an optical drive, the agent first checks if I have removable media rights. If I do, it next checks if it is encrypted or not. If it is encrypted with my PC's key, it'll mount. If it is encrypted with another PC's key, it performs a rights check against that PC and mounts if I have access. If it is not encrypted, it'll prompt me to securely format it if it is a writable medium. If all that fails, the media is ignored.

Commodore 64 owners rejoice: The 1541 is BACK

toejam13

Re: "Taking over two minutes to load a 64 kilobyte into memory was maddening."

It shouldn't have taken that long. According to "Commodore - A Company on the Edge", Robert Russel considered the disk access on the VIC-20's serial bus to be too slow. So for the C64, they replaced the 6522 VIA (with its broken shift register) with a 6526 CIA and added some high speed lines to the serial port. Same deal with the 1541. It would have been 20 to 30 times faster than the VIC-20.

Problem was, during the period when prototype boards were being reworked into their final production layout, somebody removed the high speed lines. The decision to reuse VIC-20 cases for the C64 imposed some serious space challenges. Some engineer mistakenly thought they weren't being used, so they were omitted to save space on the board. Since the Kernal's serial routines hadn't yet been updated to utilize the new burst mode, nobody realized the mistake until several hundred thousand motherboards had been manufactured. By then, it was too late.

When marketing said that the 1541 also had to be backwards compatible with the VIC-20, that limited how the serial routines could be written even further. There was also a looming deadline. So Bob Russell wrote the routines over a weekend to stay on schedule. They worked, but they sucked. Programs such as Epyx Fastload and CMD JiffyDOS worked by replacing the serial routines with optimized versions.

Anyone who has used a 1571 or 1581 on a C128 knows how much faster they are. That's what the 1541 on the C64 was supposed to be like. But due to a few bad decisions, the 1541 ended up dirt slow.

World celebrates, cyber-snoops cry as TLS 1.3 internet crypto approved

> Not "possibly". That is the common practice between the HTTPS-terminating load balancers and the back-end web servers.

Not necessarily. If the company has policies that prohibit confidential data from being on the wire unencrypted, then you cannot run HTTP between the load-balancer and web servers. This is sometimes mandated by B2B contractual agreements and cannot be avoided.

Luckily, many load-balancers these days allow you to decrypt HTTPS traffic, inspect and modify the HTTP payload, and then re-encrypt it back to HTTPS before sending it onto the web servers. This allows you to use session stickiness features while still keeping traffic encrypted on the wire.

Global race for 5G heats up with latest US Congress bill

toejam13

Re: what's the frequency kenneth?

Both. One report I read classified 5G Next Radio bands as such: under 1 GHz are "low", 1 to 6 GHz are "middle", and above 6 GHz are "high".

All of the 5G NR frequency charts I've seen so far only define bands in the low and mid ranges. Most of the bands are a subset of current LTE bands.

It appears as if some the first 5G deployments might be on bands used for 2G and 3G services today. A few carriers have stated that they're retiring those services starting next year. Meanwhile, 5G telco equipment is supposed to roll out around the same time, so the timelines make sense.

But those deployments may also be on newly acquired bands between 2 and 5 GHz. Both the FCC and Ofcom have been busy auctioning off those bits of spectrum. The carriers will probably want to put it all to good use.

> America is 11th per 100,000 deaths by firearms

About half of those deaths are suicides. Some countries do not count suicides by firearm as homicides like the US does. So it can be difficult to compare.

That said, this tragedy touches upon a couple of ugly issues. First, nobody can have an honest conversation about gun law in the US because so many of its politicians have been bought and paid for via campaign contributions from gun manufacturers and their advocacy groups, such as the NRA. They will not bite the hand that bribes, err, feeds them. Nothing is going to change until election finance law changes, and that won't happen until corporate personhood is revoked.

Second, many people in America see these shootings as acceptable losses. When you exclude homicides in poor urban areas and suicides, the homicide rate by firearms in the US drops to rates similar for Eastern Europe. They fear that without arsenals, Obama and his henchmen might show up to their farm and seize it for redistribution to poor blacks and illegal immigrants. Or they'll show up in tanks and burn them out, like Waco or Ruby Ridge. Or some other moonbeam fantasy that AM talk radio hosts dream up to keep their listeners paranoid and tuned in.

If any legislative changes come out of this shooting, it'll be to get more guns into schools, not fewer.

Re: Meh

The US banking system is almost entirely electronic now. Cheques are little more than legacy forms for initiating an ACH electronic transfer. The cheques are scanned, run through an OCR program, and then immediately submitted for transfer. Most banks and credit unions provide desktop deposit apps for scanning cheques at home or office. This is in addition to all of the paperless electronic funds transfer systems in use.

If somebody asked for a cheque, either they were new or lazy. Banks still offer old-fashioned wire transfers. International remittance services handle smaller transfers. Foreign exchange brokers handle larger transfers. Point-of-sales card networks can also be used to transfer money internationally.

Internet speeds in the US aren't far behind Europe, especially in urban areas. The real problem is that the cost of that service is significantly higher in the US.

Most VHF band II radio stations in the US now simulcast in both analog FM and digital NRSC-5 ("HD Radio"). Unlike the European DAB standard, NRSC can transmit in-channel, so there is less pressure to shut down the old analog system. Too bad that most commercial radio stations in the US are no match for streaming services.

The problem with those stories about US infrastructure crumbling is that they are often overblown. A bridge might be rated structurally deficient if the shoulders don't meet current code. And while Oklahoma and Kansas allow their roads to rot, other states do not. It is like saying that the roads in the EU suck because you use southern Italy as the benchmark.

The bigger question is where end-device manufacturing would go in the event of a trade war. Would it come back to North America or would it go to other Asian countries like Taiwan, S. Korea, or Japan? Ideally, you want to manufacture your chips close to your customers.

Secure web? That'll cost you, thanks to Mozilla's HTTPS plan

toejam13

Time for HTTP-ES

Another option would be for HTTP to follow the footsteps of FTP and introduce an explicit mode that allows clients to optionally step up to TLS mode over the native port and to allow mixed content.

With FTP-ES, a client connects to a FTP server on port 21 using clear-text. The client can then request to enter secure TLS mode. If the server doesn't support it, the client can abort or continue. Likewise, if the client doesn't support FTP-ES, the server can restrict access. The protocol also allows granular encryption of the control channel, the data channel or both.

In a theoretical HTTP-ES, a new HTTP-4xx code could be introduced that requires clients to step-up to TLS mode. It could require granular encryption of cookies, all headers, payloads or everything. Likewise, clients could automatically request TLS if it is trying to present a secure cookie to the server or if the user prefers it. It could also provide a CRC of the payload in the encrypted portion to guard against MitM tampering.

The benefits of HTTP-ES would be: no broken bookmarks, lower overhead when all you need is cookie or header obfuscation, increased protection against MitM attacks and some compatibility with external cache servers.

Re: Entertaining

>> Both technologies are said to improve colours and black levels - an obvious target perhaps, since many consumers have previously enjoyed the pictures from plasma televisions.

Quantum dots arrived to the market just at the right time. You cannot shrink the cells in a plasma monitor down to the size needed by 2160p without exceeding EU and California power regulations, which is why UHD plasma monitors will never advance beyond a few prototype models.

>> Its good see that the big players are looking at more than just resolution, and are competing on black levels and colour accuracy.

The new UHD specification (Rec. 2020) includes more than just increases to pixel resolutions. The specification calls for color bit depths of either 10 or 12 bits and a color gamut that is over twice the coverage of HD.

I'd argue that this is really going to drive the adoption of quantum dot LCD, OLED and laser display technologies over traditional LCD (which can barely handle the current HD color gamut), especially for smaller monitors that can't take advantage of 2160p resolutions. When you throw Avatar on a wide gamut monitor, people are going to be absolutely blown away by the color.

Google kills CAPTCHAs: Are we human or are we spammer?

Also, there is a danger in using animals for the captcha. Image recognition software for people has become very good. It wouldn't be terribly difficult for a spam gang to enhance it to where it can tell a cat from a horse.
