Nikki Haley sat on the Boeing board…for less than a year.

One door that seems to be working very well at Boeing is the revolving door between the company, the regulators and the politicians.

Perhaps they should consider plugging that door.

RIP: Software design pioneer and Pascal creator Niklaus Wirth

RIP professor Wirth

Thanks for making me realise I did not want to be an electrical engineer after all!

First Pascal, Fortran and Commodore PET Basic at technical university, then on to CHILL (CCITT High Level Language) and 808x assembler on ITT's public S12 telephone exchanges.

Later on to C on Apollo workstations and that was end of my professional programming track - I wonder why ;-)

And yes, I can still read and understand the Pascal programs I wrote a long time ago without major mental contortionism!

Re: Seamless Clustering

Seems to me your knowledge and understanding of VMS Cluster technology is rather limited.

Re: Unix doesn't have anything like this

Even HP didn’t manage to port the Tru64 clustering and the Tru64 cluster-enabled AdvFS file system to HP-UX after acquiring Compaq/DEC. Proper share-everything clustering requires deep integration of the cluster code into the OS and file system(s) so it is not trivial to port it from one system onto another one.

Want to feel old? Ethernet just celebrated its 50th birthday

Re: Rings

“ TCP/IP didn't have a field to indicate other protocols so we used an illegal length to indicate the other protocols.”

An Ethernet II frame does have a upper level protocol field (as have TCP, UDP and IP) but in the IEEE 802.3 Ethernet standard this field was redefined as a ‘length’ field creating the problem (and solution) you described.

Sir Lancelot

Re: Rings

DEC used its own MAC addressing scheme to ease DECnet to MAC address mapping. Given the destination DECnet address the sending computer is simply able to compute the MAC address used by the destination without having to use an ARP-like broadcasting system. It does not have anything to do with the MAC address size. The embedded MAC addresses were used by for example the DEC cluster protocols which ran quite happily and simultaneously with DECnet.

Re: The modern museum

“ About all I remember of VMS is that every time the team dealing with it got a new hire someone would have to deal with a machine clogged up by a full disk because VMS defaults to creating new versions of files instead of overwriting.”

So the team didn’t seem to know about (proactive) version limits available on files and/or directories? I remember teaching that in the “VMS Utilities and Command” course when working at Digital.

Alert

Re: "the FAA remains focused on [..] returning the Boeing 737 MAX to passenger service"

Firts: MCAS is not about fuel burn. It's about correcting unwanted aerodynamic behaviour in very specific circumstances such as being in a banked turn with high angle of attack close to a potential stall.

Secondly, the "AoA Disagree" alert does NOT signal MCAS activation. It simply reports an excessively different AoA being reported by the left and right AoA sensors of the 737 Max.

Singapore Airlines 777 catches fire after engine alarm

Sir Lancelot

Re: camera phones

The Qantas Flight 32 Airbus did not have an engine fire. The Qantas crew was correct not to evacuate because of the hot brakes (they landed fast because of degraded flap functionality), the fuel leaks and the inability to shut down engine 1.

In the SA scenario people were not evacuated of a plane with an engine and a wing on fire. That wing carries a lot of fuel on a 777 ER (extended range). My guess is that SIA crew will have a bit of explaining to do as to why they did not immediately evacuate via the left side exits. The crew and passengers were very lucky to escape as they did!

Re: Why change the system?

Thanks for the downvote on a purely informational post. The loonies are really taking over the Reg I guess.

Sir Lancelot

Re: Why change the system?

Unfortunately the TETRA standard only covers the interface between the TETRA network and the TETRA handsets/devices. Internally (i.e. in between the TETRA switches) the TETRA network uses vendor-specific, proprietary interfaces. So you'll need to rip out all your TETRA switches and replace them with new gear supporting the required functionality. Nicely played by the TETRA vendors!

'Open' SIMs, brain chips and Google's Nest: What to expect in wireless in 2015

Sir Lancelot

It does needs a bit more

Remember the SIM (soft or hard) is pricipally used to store the IMSI(s) i.e. the handset's identity. Currently in the large majority of countries (ITU members) the only organisations allowed to manage and distribute IMSIs are MNOs owning an operational wireless GSM/LTE network. So even with softSIMs or handset vendor provided SIMs you would need to have an agreement with a MNO to get the IMSIs for your SIMs. Organisations thinking about rolling out M2M applications are also confronted with this problem and so far the MNOs are doing whatever they can to retain control over IMSI distribution. The critical part is not the SIM (hard/soft/reprogrammable), it's the IMSI.

Sir Lancelot

This would require (1) existing M(V)NOs to abandon their SIM-based network approach - rather unlikely - or (2) new SIMless networks to be established - any takers? I'm afraid the GSMA/ETNO train has left the station quite some time ago and will be hard to stop. The whole operator-centric SIM/IMSI approach has been engineerded into the GSM standards with the complicity of the ETNO and ITU and they are not in the habit of listening to what the end user wants.

An Apple SIM is not a soft SIM and it requires a non-Apple network

"...and Apple included a "soft SIM" option in its latest iPad. This allows the user to select from a list of operators (and switch between them) when activating the device, passing the control from the carrier to Apple."

Wrong - Apple's SIM is not a soft SIM, it's a simple physical multi-IMSI nanoSIM (with limitations e.g. AT&T swap restrictions) still requiring network and suscription support from a participating MNO. The Apple SIM can still be replaced by whatever SIM you prefer so control has not passed from the carrier(s) to Apple. Apple has other means to put the pressure on carriers such as 4G network certification and commercial terms for the promotion and sales of handsets. Or is Apple thinking about becoming an M(V)NO?

How iPad’s soft SIM lets Apple pit carriers AGAINST each other

Sir Lancelot

Re: SIM

"Carriers and manufacturers would love to kill the SIM, which has made the consumer king for over 20 years."

You might want to talk to the GSMA about this. They actually fiercely object to the idea of a soft or virtual SIM according to them for security reasons: http://www.gsma.com/connectedliving/wp-content/uploads/2014/10/Embedded-SIM-Toolkit-Oct-14-updated1.pdf

And as mentioned before: for mobile devices it's not about the hard, soft, virtual or embedded SIM (the vehicle). It's about the IMSI and the encryption keys (the contents of the vehicle) stored on the SIM. In the large majority of countries currently only mobile network operators and mobile virtual network operators are allowed to issue IMSIs which are preprogrammed into the SIMs and distributed to the network users. There is no particular good reason why IMSIs should be controlled by M(V)NOs. Only very recently the GSMA has released an architecture and standards for "Over The Air" reprogramming and switching of IMSIs on embedded SIMs because they were pressured to do so by the growing M2M community that does not like its devices to be tied to a specific M(V)NO during the typically long contract period. Mind you there currently are no wide-scale implementations available of this OTA embedded SIM nirvana.

By the way: in the past the GSMA also opposed the idea of the OTA SIM reprogramming!

One other thing: the currently launched Apple iPads still allow you to replace the Apple SIM with the SIM provided by an operator of your choice so make sure you target your arrows at the proper villain. It's a bit silly to condemn Apple for something they might be able to do in the future I think. Predictive crime analytics at work?

But there is hope: maybe in a number years from now babies will be born and will come with an embedded SIM and IMSI supplied by 'fill in whatever organisation or company you dislike and/or distrust' which can then be linked OTA or good old dipswitches with its preferred M(V)NO ;)

"Bird into engine results in a bit of a cough out the back, and the engine casing being lined with overcooked finely minced bird. A cleaning job for the apprentices...."

You are a bit optimistic. Bird ingestion can cause major damage to the compressor section of a jet engine eventually leading to compressor blades breaking away from the compressor disk.

I hope in that case the repair is not left to an apprentice...

BTW Jets have multiple pitots at different locations on the hull. The only single bird able to take out all of them in one go is the ... flying elephant. Wasn't he called Dumbo?

B166er:

Why don't you read this first concerning the 'accuracy' of the Popular Mechanics article:

http://www.pprune.org/rumours-news/466259-af447-final-crew-conversation-36.html#post6891763

"You accuse people of posting nonsense with nothing whatsoever in your spew to demostrate that."

One example but there are many more: using GPS-derived ground speed in an analysis of the aerodynamical state of a stalled airplane descending in a tight right-hand turn!

"I think most intelligent readers can determine from the flight recorder cockpit transcript roughly what happened to those 228 people without being pilots.".

Of course they can (the plane crashed and the people died, didn't they?) but determining what the probable causes and contributing factors of the accident are, is an entirely different thing, isn't it?

"By the same logic, are you unable to grasp concepts that don't fall squarely within your area of expertise?"

I really think you need a bit more than grasping a few concepts about flying to be an accident investigator...

"If you ARE a qualified pilot, perhaps you could answer an earlier question: Why is it that the low altitude alarm doesn't sound until 2000 feet during midflight?"

A simple one to answer: it was not designed to measure heights larger than 2500 ft above sea/ ground level (the range of the radio altimeter). You do know the RADALT is part of the Groud Proximity Warning System, don't you? This system was designed to prevent CFIT (controlled flight into terrain) accidents. The chances of encountering terrain are rather slim at flight level 350 don't you think? The RADALT is only used by the GPWS and by autolanding systems. Pilots are not allowed to use it as a primary altitude measurement system. Your primary altitude measurement system is a barometric instrument with a selectable reference height/altitude/pressure.

On top of that: in IMC pilots are expected to scan a number of essential flight parameters including altitude and vertical speed. From the interim report released by the BEA (did you read it yet?) it is clear that all AF447pilots where perfectly aware of the plane's altitude and vertical speed during the decent. You do know that altimeters and VSIs use the static pneumatic ports which were not iced up, don't you? In others words: pilots should not be dependent upon altitude alerts to know what altitude the airplane is flying at! Scanning your instruments is one of the primary pilot tasks!

Better stick to simming...
