Comment Re:Will never happens (Score 1) 270

These videos mostly either deliberately mis-state or overstate the issues - try some fact checking for once. They are made by someone who makes money by stirring controversy to push up his video views and make money and "debunking" hyperloop is a massive cash cow for him. He started off with fairly reputable science analysis but over the years moved to more emotive/controversial topics as these made him money.

A lot of the arguments in the video are based on the "alpha document". The document itself points out it is about ideas and not detailed either in engineering or physics analysis - just a starting point for detail to be added later and ideas to be used or discarded with further analysis. It is not a fixed blueprint for the final design.

SpaceX/Hyperloop themselves say "low pressure" and not "vacuum" - the pressure in the tubes is expected to be around the same as a jet plane experiences which is easy to maintain compared to a hard vacuum. The 99.9% vacuum that is often stated did not offically come from Hyperloop but is a figure that was mentioned as a "possible/maybe" very early on by latched onto by the media after one person gave an off the cuff remark.
Low pressure will be less force on the walls compared to what is stated in the videos.
The crossbraces shown in images of the pipes are for transport/lifting support where there will be uneven forces (not the same as the even pressure forces once sealed) and once the pipes are joined and mounted are not needed.
The mythbusters experiments showed that they had to do *significant damage* for the tanker to collapse and tankers have much thinner skins than the hyperloop track does.
Sudden shock point pressure on a surface/material/tube is not the same as constant or slowly changing uniform pressure.
Sealed expansion joints are a many times solved thing for low pressure systems and long pipelines even on the scale we are talking about for hyperloop.
As are station "airlocks" and emergency air for passengers
The crash/failure would not be as stated because 1) low pressure not vacuum and 2) vehicles will not be tight to the walls as in the youtube glass tube experiments.
Cars being pushed then released on a surface lose speed due to friction once not being pushed - surprise! Physics working as expected. The competition was about an effective shape of the pod in low pressure in the tube and not about propulsion/drive/levitation/wheel friction for the final system. Also is it a surprise that a very short test track can't reach the speed in 10 seconds AND THEN STOP safely before hitting the end where the speed of a full scale system could over several minutes of acceleration over several dozen miles?.

He didn't access his own account. He set up a "fake" account for a 'fake' employee that didn't exist which could be done even using the HR link if he he had access to add records to that database. Or he could have set up additional access on some other employee (say a driver) who rarely used the wider computer systems and wouldn't notice the extra access.

But HR links like that don't really work in the real world anyway. It doesn't allow for most large corporate set-ups where mainframe needs to talk to linux box that needs to talk to an oracleDB that needs to be accessible by a java batch job that needs to write output to the windows domain server file system so a human can check it before uploading it to an SFTP gateway box for an external customer to collect.

You don't just have accounts that are pure user accounts. You need mechanisms and accounts to allow system to system communications and logins for moving data between automated systems and for a large company it would be easy for an admin with sufficient privileges to hide a back-door amongst all these inter-system communication accounts (or even just hijack one or two legitimate ones, having copied passwords and other keys).

They tend to hunt down the pirate radio broadcasters not because of copyright, rather becuase of the radio broadcast part, causing interference with legitimate broadcasters as well as (on poor setups) wider interference with TV, cellphone, wifi, emergency service comms etc. Even if a pirate radio station broadcast nothing but public domain and self produced works the are shut down. The copyright stuff is just a bonus to the prosecutors.

London taxi (black cab) drivers are different from private hire (usually "normal" cars with a meter fitted as well as slightly more exotic things like limo and minibus hire).

Black cabs have privileges that private hire don't with regards to road access, taxi ranks and other similar things and have the requirement of the Knowledge in addition to the checks required for private hire. Private hire cars (which normally need to be "pre-booked" by phone) or have a limited number of allowed pick up locations, have licences that require a less stringent check, focused more around basic suitability for driving with passengers, correct fare calculations, knowledge of a smaller area of London around where the taxi operates from, criminal checks etc.

What's more, most of the manufacturers (from phones to consoles to laptops) don't give a crap about your data and will likely replace your unit with a refurb rather than trying a direct repair. Your game saves? Gone. The photos of your kid? Gone. Your dissertation? Gone. Your accounts? Gone. Most independent repairers will care. Dead IPhone because you got caught in the rain? Your headphone jack broke? The charge connector broke? Apple (or any other manufacturer) don't care and will likely charge you 80%of the purchase price for a refurb with 3 months warranty and unrepaired issues that mean it will fail in 4. However there is a good chance a good independent will be able to either repair the damage directly or at least get you all your data back - even though Apple (or any other manufacturer) make this hard for them by not providing them with the parts and schematics needed. If they had the parts and information recovery would even be more likely.

The manufacturers claim safety issues - for example that if they made batteries available they might explode because someone fitted them wrong. The truth of the matter is anyone willing to do their own repair can already get hold of cheap, usually knockoff or QA failure batteries on the internet to do their repair anyway. If the manufacturers provided genuine batteries then there would be LESS chance of explosion.

Also they make out that the majority of self repairs in electronics would be attempted at home, where in reality most people would not try themselves but take the device to a local independent shop for repair where the staff (mostly - cant account for some idiots in any field, including current authorised repair shops) know what they are doing.

I've had whole series of meetings involving several very senior overpaid staff that ended up with the conclusion we don't need to do actually do anything and don't need any more meetings when that was obvious to anyone with half a brain before the first meeting. And the management then effectively promoted the organiser of those meetings based on the do nothing outcome of organising unneeded meetings not costing us anything to implement...
