No-boom supersonic flights could slide through US skies soon

dinsdale54

Tell me you haven't flown on Concorde without tellimg me you haven't flown on Concorde :lol:

The seats were plenty comfortable with loads of legroom. Headroom was limited but that's wasn't a problem once you are sitting down. The wine list was rather good. I don't recall any Foie Gras or caviar but I did have a decent steak - although obviously not as good as at Peter Luger the night before.

In 1998 my ticket was ~£800 London to New York, coming back on Concorde. Demand was quite low for the early flight back hence the good deal.

Re: If the orange eejit gets a whiff of this...

A customer I used to deal with had a class A. Their chief technologist had decided in the early 90s that the internet was going to be a "big thing" and simply wrote and asked for one. It also meant that at the time I was dealing with them - late 90s - all the desktops in the company had a valid internet facing IP address!

It looks like they have sold off a lot of their space already, keeping a mere few hundred thousand addresses for their own use.

Europe's largest council kept auditors in the dark on Oracle rollout fiasco for 10 months

dinsdale54

Re: The real truth ?

The spec is the spec.

It's what has been agreed to be delivered. If you change the spec then you are changing the contract - that doesn't usually come for free.

In the early part of my career I worked for a company that supplied systems to local government written in Oracle. The system was decently complex and did what it said on the tin. Most councils took it as is, or with a few customizations which were generally done on a T&M basis.

The couple of councils who asked for extensive customization were back using the standard system within a few years. They discovered that they weren't actually as special as they thought and the costs of maintaining a customized version outweighed any predicted benefits.

The quality of IT departments at the councils was a mixed bag. Some were pretty good while some didn't really have anybody who knew what they were doing. There were very few Oracle skills there. Somebody who actually got good at Oracle would likely be off for a better paying job pretty soon.

Mixing Rust and C in Linux likened to cancer by kernel maintainer

dinsdale54

Re: "it would suck"

A company I used to work for rewrote/ported its OS from a hand-rolled kernel to BSD. There was over 15 years of development work in the original and it took over 10 years before they had feature parity in the new one. It was a fair bit smaller than Linux.

As you say it's a HUGE amount of work. If you are relying on a small number of people, some working in their spare time to do this work you had better make a pretty good case for doing it.

Open source router firmware project OpenWrt ships its own entirely repairable hardware

Re: So WiFi only for client connections. Really?

I doubt it as well.

This is why I purchased a Turris Omnia. The chunky CPU specs allow close to line speed (1gbps) routing. My previous home router couldn't handle the 250mbps connection I had at the time.

Hardly ANY reviews of home WiFi routers seem to mention the actual routing performance, just the WiFi bandwidth. A budget router may well not have the necessary CPU horsepower for faster internet connections.

Crypto scams rake in $5.6B a year for cyberscum lowlifes, FBI says

dinsdale54

Re: Friend got scammed....

While learning about security is a sensible precursor to getting in to crypto, I'd start with considering the complete lack of any value to start with.

A friend is a greybeard programmer and at least 20 years older than anybody else he works with. All his team were in on crypto except him. At their last meeting he discovered that every one of them was out a decent amount of money from their 'investments' I think the smallest loss was about £8000 up to >£30,000. Somewhere somebody made money from them but the net is a large amount of energy was expended to move money from them to somebody else.

At least Charles Ponzi had a believeable story he was touting around the markets. Crypto doesn't even have that.

Former Fujitsu engineer apologizes for role in Post Office IT scandal

dinsdale54

Re: Possibly controversial opinion...

I agree with some of this. He does seem to actually be trying to answer questions and isn't suffering from the intermittently faulty memory of many of the witnesses.

However on the technical side - which I guess is why most of us are here - the issue I have, and this was the same with his colleague Anne Chambers, is the clear assumption that the system was working fine and if they couldn't find a problem in the data after a cursory check then there wasn't a problem and it was somebody else's fault. To find bugs you have to actually go looking for them.

The whole culture of the PO and ICL/Fujitsu seems to have been to see everybody else as the problem when a good hard look in the mirror was needed.

systemd 256.1: Now slightly less likely to delete /home

dinsdale54

Re: Too complex!

Early systemd looks exactly like a copy of the Solaris SMF - which fixed a number of issues with the init system - dependencies, parallelism etc.

I recall there was discussion at Sun about whether it was too big a change to the traditional init system. Systemd took that big leap as a starting point and has spent the next 15 years trying to devour all of Unix.

I have no idea whether that was always the plan or it's just a case of feature-itis.

Starlink offers 'unusually hostile environment' to TCP

dinsdale54

Re: We love it.

The issue that forced me to learn about this (referred to in another post) was a customer backing up data from Tokyo to Singapore IIRC. Plenty of bandwidth but significant packet loss.

My company ended up re-writing the data transfer protocol to use multiple tcp connectrions and making the send windows proportionally smaller. Packet loss then caused much smaller retransmits.

dinsdale54

I see lots of comments about how Starlink is fantastic - which I agree with - but it's not what Geoff is discussing.

I've put in more time than I ever wanted to dealing with high latency jittery networks with packet loss. You can get in to all sorts of issues with large send and receive windows causing enormous retransmits at significant jitter or small amounts of packet loss. ~1% packet loss on a high latency network will pretty much remove your ability to to large data transfers, regardless of the theoretically available bandwidth.

The congestion control algorithm makes a big difference here. There are lots of them - which is a sign that none work well for all use cases. The author is making sensible suggestions as to which ones are well suited to Starlink.

Return-to-office mandates had senior employees jumping ship

A friend who did a couple of years working in Japan for a large computer manufacturer described their decision making process exactly like this. Meetings are where decisions are communicated, not made.

It does put the onus on the manager to ensure they talk to all the relevant people and listen to them but get that right and it's an efficient process.

A couple of IT projects I worked on for the military were similar. It took a while to understand the culture but it worked well - If you had a good manager.

Re: Serpent

The AES spec determined that all entrants would use a 128 bit block size and at up to at least 256 bit key size. I believe Rijndael did offer larger block sizes but once it became AES that feature was dropped.

At the time, encryption was very CPU heavy. No custom functions in mainstream CPUs like today. We sold quite a few nCipher cards to customers wanting to run VPNs and suchlike. Limited use cases for them these days.

Re: We dont go for "uptime" records

Yes, that's generally a good policy. The time to find out whether a system restarts is not when you are trying to restart everything after a power outage.

Yes, there are likely caches in RAM which need to be rebuilt and will increase latency for a while.

Some years back I had an angry customer (investment bank) to deal with. One of our servers had crashed and taken down a trading application - despite being in a failover cluster. What the bank then discovered was that they didn't know how to restart the service - about 20 applications on a similar number of servers. The services had to be restarted in a specific order - which they didn't know since everything had been running for several years uninterrupted.

This is when I also learnt the lesson that the more somebody shouts at you, the more likely that it's their fault.

When red flags are just office decoration: Edinburgh Uni's Oracle IT disaster

His WTF moment happend when the CEO passed him in the corridor and said 'I hear you are getting great benchmark numbers on the new systems'

It had only taken about 3 layers of management speak for the message to completely reverse from the truth.

Former Post Office boss returns CBE to sender over computer system scandal

Re: So what was actually wrong?

Here's the code and the explanation of why it's moronically stupid.

This extract from EPOSSCore.dll has been written to reverse the sign of a

number and is equivalent to the command :-

d=-d

Public Function ReverseSign(d)

Ifd<o Then

d= Abs(d)

Else

d=d-(d*2)

End If

ReverseSign = d

End Function

Whoever wrote this code clearly has no understanding of elementary

mathematics or the most basic rules of programming.

The guy brought in to assess the system and remedy issues wasn't allowed to rewrite it and was moved on when he complained.

If somebody says they have a new architecture and part of the pitch is 'we can fix problem [X] in the compiler' - You should probably run rather than walk away.

Apple might have to pay that €13B EU tax bill after all

dinsdale54

Or an 'error of judgement' :)

TBF this is actually largely how tax law works. If you are found liable for a tax bill, the govt just wants the money. If you pay up, you generally are in the clear (apart from little people doing their tax returns obviously)

The important bit is not to keep evading tax after being investigated, that's when they throw the book at you. See Lester Piggott / Bernie Ecclestone. In Bernie's case, it was more of a leaflet they thew at him, in exchange for another £650 million.

It is 20 years since the last commercial flight of Concorde

dinsdale54

Re: Gorgeous aircraft

My main memory is that they were noisy. I flew pre refurbishment and sitting in a window seat you had to speak up to the cabin crew in the aisle. Excellent wine list! I believe the work of Jancis Robinson.

The interior was small but once sitting down it was fine. The seats were comfortable, if a little vintage looking and you were only there for a bit over 3 hours.

I was booked for a 2nd flight when they were grounded.

I also cycled to Heathrow to watch the last commercial flights land there - 3 Concordes landing one after the other. It was VERY busy on all the perimeter roads.

Oh yes, the windows got hot to the touch.

Oracle pours fuel all over Red Hat source code drama

Re: Opensolaris anyone? @containerizer

Sun converted from BSD to SVR4 to try to end the Unix wars which set Unix back several years. On balance this was sensible.

Given that a lot of SVR4 IS SunOS, it wasn't a major technical challenge but it did result in a fair bit of change for existing users without any immediate benefit.

Sun was very innovative for many years. SunOS and then Solaris introduce a load of advanced features - some mentioned previously - so if you were on Solaris, you could do things that other people couldn't. In the early years there was NFS, NIS, RPC and then later SMF, Zones, ZFS, DTrace etc.

Working with Solaris was a good place to be for a long time.
