Spies would need SUPER POWERS to tap undersea cables

imanidiot

I doubt they splice

I have worked with fiber optics cable. Splicing is indeed not a trivial task at the best of times (On land, in a cleanroom, on a table, with plenty of light, equipment and time). The biggest problem however is that it leaves a trace. Any splice generates internal reflections and increases signal damping. The increased cable losses are probably immediately measured (afaik they are pretty much continually monitored). Which will then lead to the cable owner connecting a different measuring device called on Optical Time Domain Reflectometer. It'll tell them exactly WHERE the cable was respliced by someone who is not them to within a few dozen meters. And unless they were paid of by the NSA I doubt they would not send an ROV down to investigate the next time a repair ship was nearby. And if the NSA would go through the trouble of paying off the cable owners I doubt they wouldn't just tap into the endpoints.

Splicing is not the tool for the job here. There are other, less detectable ways of "tapping" into a fibre cable.

Re: Green Prince of Darkness

I (more or less) get what you're saying. I just don't get why it's relevant. The article doesn't really speak about quantum leaps of performance or massive changes in recharge cycle limits. Just prevention of damage to cells within the current cycle life. Even just extending the average lifespan of a lithium cell is a worthwhile cause with the amount of use they are currently getting.

Re: And of course...

Problem is, people stupid enough to fall for phishing mails are not likely to be deterred by an additional oddity here and there. They'll just assume "someone made a typo" and laugh at the stupid bank while providing their email, username, password, PIN, height, weight, eyecolor, ring size, what they ate that morning and when they last took a crap.

My point being: Stupid people will be stupid.

Re: Collision vs other explaination

It's possible both bits of rock where ejected after an impact of a much larger body into another larger body, giving them very similar orbits and speed. That would allow then to come together very slowly, possibly after bouncing off each other a few times.

Re: kickstarter

Quit your whining. We all know you are talking about Oculus. You kickstarted the production of the first Oculus Rift dev kit, you received your Oculus Rift Dev kit. End of contract. You did not, and where never lead to believe you where investing in the starting/expansion of the company, so you have no right whatsoever to whine what happens with/to the company after the contract/purchase/deal YOU had with them is fulfilled. And keep in mind, if Oculus had racked up massive debt and folded, even after delivery of the Dev kit, YOU WOULD BE OUT OF MONEY.

If you would have bought shares of the company, you would have paid a LOT more.

Re: Post-Lohan...

The problem is not that getting stuff to orbit means lifting it very high. The problem is an orbit means moving sideways. REALLY fast. You cant get that sideways movement with a balloon. You do cut the atmospheric drag portion (mostly), but its still a LOT of deltaV to achieve orbit

Re: No thanks

Steam is great for all those old games that come by for a few bucks in the sales and make you think: I should play that. I certainly wouldn't buy any big price games directly from steam.

When games are easily available directly from the source, I don't see the added benefit of steam.

Re: Compass

Compass

Well known problem in big metal ships. Apparently they used to sort it with some strategically placed magnets (or a big lump of steel)

Well known problem on airplanes as well. Even on fiberglass gliders with little to no metal components a compass will be noticably out of alignment if not corrected. (And TINY amounts of metal can already influence it.) A sunroof and aluminium roofrack are not going to cut it, there's still way to much metal in close proximity.

On aircraft the compass has a small tray for mounting small magnets or iron blocks, used to counteract the influence of the aircraft frame on the indication.

I doubt the LOHAN compass will have any sort of adjustable compensation built in. It would still be a good idea to slug it up a hill, set it on a non magnetic table (Preferably something you coble together from some old planks without using ANY nails or screws) pointing due north, power everything up and stand well back while noting what the compass reads. Then turning it 90 degrees, rinse, repeat.

On the video is also seems to me like the canard has some trouble returning to neutral after making a full deflection. Is this just an illusion or is the servo drawing much more power at that point?

Even more fun as a mechanical engineer

Where a single question can show the speaker to be both incompetent and a danger to others with a single question.

A single question like: So, about that final design. That rear leg is about 80 mm in diameter right? Thick walled tube probably? Have you thought about the buckling load? (Speaker had very confidently stated that all loads were within limits with a design some 50% under the normal weight of a competitors unit. The entire audience immediately knew what was meant, and most instinctively knew the rear leg would buckle like a match. There were several other design flaws I wouldn't expect a first year student to make)

Re: As always, good work

"I agree.

And to misquote you "a single spike mounted into the rear", you are a bit of a pervert. (Or is that me?)"

You don't know the half of it *suggestive eyebrow waggle*

In all seriousness, this might be of interest to the LOHAN team: http://www.grc.nasa.gov/WWW/k-12/airplane/tunbalmnt.html

I realise the LOHAN testing is not really for the purposes of finding the aerdynamic forces on the airframe, but this kind of mounting still allows for uninhibited flow around the model.

More clearance from the roof of the car will be needed in any case.

As always, good work

And as always I feel like voicing a concern ;)

Testing on top of the van is certainly useful, but if the goal is control algorithm tuning the airframe will have to be mounted in such a way that local flow conditions approach those of free flight. The current rig is too close to the roof and too bulky to allow free flow over the control surfaces. Ideal would be a single spike mounted into the motor mount from the rear. With the upright part of the support located about a quarter span behind the rear of the plane.

Re: to the pub

I think its supposed to be a derivative from the "our Father" prayer. More correct then would be: "Sicut inter sidera et in taberna". Between the stars as (it is) in the pub. It seems incorrect because there is a bit of sentence missing, where the implied "it is" comes from. I don't really know how to fix that without making it a rather lengthy sentence. Plus my latin is a little rusty. I last translated anything about 7 years ago.

Edit: also, it should be taberna at least. I think Caupona would be better suited in meaning (inn, tavern, canteen. More fitting of the meaning of a pub) but less recognizable by those not learned on the dark arts of Latin.

Re: Ministry of Truth demand more LIES....

While we ARE getting lied to about many things, most data simply DOES point to changing weather patterns over the last few decades. Whether this is natural or influenced (and to what degree) by mankind is less clear cut because of the dense overgrowth of "greenie" sponsored BS "research" in that area.

Dammit, Foxconn: Where's our 1 MILLION-strong robot ARMY?

imanidiot
Bronze badge

Not really surprised

"locking screws, components and polished appearance", meaning exactly what cheap and readily available automation systems do.

Automation takes an investment (plus a lot of time investment in development of product specific tooling and programming) that needs to pay back. Such an investment is only worth it if the cost of labor is significantly more than the depreciation of the equipment used. The labour for Foxconn is currently still cheap enough that significant investments in automation systems are just not worth it.

The main reason for the investment in "Foxbots" now is probably more about quality than about labour costs. (Robots tend not to leave fingerprints, smudges and scratches on parts like meatbag workers tend to do)

Look at what most growing companies in the western world goes through when growing. It starts of producing small numbers of parts with significant portions of manual labour. As labour cost per product starts rising, more automation is introduced. Until a point is reached where a significant portion, if not all, production is automated. Labour cost is the most significant driver behind automation. Foxconn has access to cheap labour, so has little drive to automate right now. If pay per hour keeps rising, more automation will be needed to stay competitive.

Alabama quadchopper hits THREE THOUSAND FEET next to AIRPORT

Re: I've posted a rant here before

@Chris lively, I'd agree with you except for the simple fact that anyone who doesn't know airspace structures would also not know where airlanes and airports are. (Not to mention the existence of low-flying transit routes for military jets, forbidden airspaces, etc)

@Cynic_999, basically the same region. Anyone who doesn't know airspace won't know where those takeoff/landing areas are. Thus they shouldn't be flying that high. (Add to that the fact there is VERY little reason for a normal powered model to go that high. I can understand a larger span glider model getting extra altitude, but I would like the pilot to know where he is flying with regards to other traffic.

so I'll just keep it short.

I'm a pilot. I have a piece of paper that shows I know airspace structures and where I can and cannot operate an air vehicle.

Anyone operating anything (remote or otherwise) over 200 feet altitude (I think 400 is WAY too generous already) should IMHO be able to show a similar piece of paper.

Re: Looking good

Additional question: The TTL converter is just hanging in free space from the USB connector atm? Will it receive some additional support in the "up and down" direction? Because as it is currently sitting, it'll put a lot of stress on the solder joints for the usb connectors on the PitS and converter board. And from experience, solder joints are NOT structural. (Especially the bonding of the copper trace to the board is prone to breaking loose from vibration induced stresses.)

Packing chutes is not always easy

Packing a regular chute is not THAT hard. Packing an emergency chute takes some added effort and care (they are folded differently from the "standard" and being the ONLY chute in the pack it better come out right the first time. And fast). I can imagine folding a giant hypersonic parachute is not an easy feat. One wrong loop in the risers and you're shit out of luck.

My hats off to the NASA boys for pulling this off. I'm also impressed at how fast they manage to kill the stabilising rotation after the motor burn.
