That the difference in setup for the plane was one position on a dial among a cluster of similar dials, in the middle of the console, with no indicator lights and no change in any other setting if you instead wanted 'takeoff', kind of reveals the plane wasn't the one at fault, the designers were. This accident actually caused airbus (and other manufacturers) to greatly simplify the design of the cockpit, making different operating modes much more clearly indicated, and taking fewer steps to switch between them. This more human centric approach to interface (as opposed to engineering centric, or feature centric) has served them very well, and is now the industry standard in all new aircraft design. It's something other industries should pay much more attention to.

chitoryu12 posted:The story of how a team was required to tell a company how their own petrochemical plant operated because they lost all the important files. "In the early 2000s, several of my colleagues and I retired. In the late 2000s, the company remembered that this plant existed, and thought about doing something with it" The concept of "Institutional memory" is interesting, I experienced something similar to this working in a large multinational, after 6 years on his job, the boss of our department discovered we had an office employing a small team in another city who were working on gaining permission to build a gas power plant. The previous boss had signed it off 7-8 years prior, and they had spent the last 7-8 years doing studies and applying for all sorts of government permissions. When you start looking at multinationals with billions a year in revenue and billions of costs, I wonder how frequent it is to end up with teams working on things that some big boss signed off on, and then following a management reshuffle/cost cutting the new person who technically should be in charge of them isn't aware they exist. While the people on the project don't really want to bring it up because they are afraid their department will be shut as part of the cost cutting, especially when what they do it isn't really directly related to the business's main area.

We had a bunch of freezing rain last week and it caused a massive pile-up on one of the highways as the hills became coated with ice. Somebody happened to be out walking around 2am and caught a massive pileup on camera. http://koin.com/2017/02/03/dozens-of-cars-slide-on-icy-i-5-in-portland/

I feel that a lot of software development is similar, where there's code nobody's touched for ten years, it's not documented or is poorly documented, stuff that seemed like a good idea at the time now looks strange and unconventional, and you just have to reverse engineer it to figure out how it works. Also, I used to work for companies that sell computerised ways of storing and organising plant data. I noted that there was a tendency sometimes for customers to think they could just throw computers at the problem and that would solve it. They hadn't implemented good data management and management-of-change policies in the first place, and that was the core problem. Our stuff would allow them to computerise processes like that, but not bring organisation to chaos just by itself. Also: apparently engineers REALLY loving love Excel spreadsheets. Sooo much writing importers to load data from Excel spreadsheets...

More than once when writing these spreadsheet importers, the only sample data we had on hand was password protected. Good thing Excel password protection is a joke. xlsx files are just zip files full of XML, so you just unzip them, find the fields that switch on password protection, and erase them. Et voila! You can open the data without a password and get the effing job done. Reluctance to let us access systems we were helping implement, or data we were helping import, was also a PITA. We weren't competitors, we had no goddamn interest in the data other than to help get it into our system, and maintenance data is hardly sensitive information anyway! To say nothing of getting our software installed or upgraded by screensharing with a tech in the Philippines to access a server in Singapore for a company in Perth, and having to dictate every step of the operation for him to type in, because they were incapable of reading either the packaged manual nor the idiot-proofed install steps they demanded we write for them, and because granting me direct access to just do it myself in 5 mins would be verboten.

They are very powerful, yes, and there are some very clever, creative spreadsheet based systems out there for controlling the quality of engineering data. But past a certain level of complexity (and I posit a chemical plant is at that level) it works better to use a specialised program.

That plane wasn't told to land. It was supposed to do a low-speed flyby at 100 feet. Instead it did a low-speed flyby at 30 feet. The crew was distracted and took too long to apply power, it skimmed the trees, and went in.

the yeti posted:I think hyperlynx means you want a program designed and built to do whatever task it is that's led you to create a pile of formulas and scripting in a spreadsheet. Meanwhile I've seen enough several thousand dollars per seat programs who's entire function is to supply managers with control charts while the engineer who knows how to use Excel and Minitab is on vacation because the Six Sigma god demands sacrifices of charts. If nothing Excel becomes a necessary step in a workflow because its useful for marshaling data from one function to another. The major functions something like a chemical plant engineering team is working on are simulation, trending/stats analyses, and financial. You've got various simulation programs that are incredibly useful like ASPEN or pipe sims, you've got Minitab (hopefully, or they've cheaped out and given you a more academic focused stats program) for stats, and SAP for financial, and Excel to tie them together or massage presentation modes together. You can pay big bucks per seat on modules that tie ASPEN and plant statistics together and everybody has a Six Sigma flavored stats program to sell but its hard to argue with Excel being relatively pennies for a seat. But a lot of it goes back to Keiya's point. The common thread of ASPEN, Minitab, SAP, and Excel is they expose databases and database manipulation in a way you don't need to learn C, javascript, or SQL and there isn't the critical mass of the magic combination of industry expert and programmer to create anything more bespoke than ASPEN sims, Minitab templates, SAP batches, or Excel sheets per process.

Green and orange have custom cannon plugs that I would call overengineered except they actually do have to be that good to survive the environments they wind up in. Like, getting sprayed with 150psi cutting oil and lathe chips inside the business end of a swiss lathe 24/7 for years. The purple cables will have a DB9 tee on the end at a 45° angle ao they can fit onto a panel and still be piggybacked to each other. Internally, purple is a single shielded twisted pair of 16ga super-fine stranded. Green carries the 24v encoder signals from the servo back to the drive controller, orange is 600VDC PWM to the servo. E: that is easily $3M worth of gear just visible in that photo nevermind the actual servomotors shame on an IGA fucked around with this message at 19:18 on Feb 5, 2017 |
