Uber's venture capitalists and investors are eventually going to get skittish.

Which is why there was such a rush to try and IPO it over the past few years. That way the founders and investors could get out with their cash and Wall St. (read - your 401(k)) would be left holding the bag. After all, the Fed is pumping so much printed money into the system something has to soak up all that extra cash. Nowadays it's IPO's. But god help us when the bottom drops out of the market NEXT time...

Comment Re:installed by a contract third-party IT speciali (Score 1) 44

The $15,000 in "cumulative savings" I referred to will probably cost more in the long term. In the router case, the issue did cost them more in the end. I had to bill them for an unscheduled emergency call, troubleshoot what was going wrong, then I had to take out the $50 router and walk around and reboot every terminal. In this instance, they did save the $250 initially quoted ($200 if you count the $50 they gave the bartender's nephew) but ended up paying $400 and the money spent prior was also wasted (because the hardware is now just collecting dust on a shelf).

This is what the customer thinks (almost uniformly):
Every time I have to call this guy, it costs me $150, if I can do it myself, it costs me $0 (or $25-50 for cousin IT to do it).

For small-midsize organizations, you're dealing with perhaps a couple or so contractors charging you $50k or more for IT services, still cheaper than hiring a dedicated IT. So one of the HR people "knows about computers" and becomes the "IT guy", they don't have to "pay" the contractors anymore for small stuff because "that guy from HR" knows about computers, right? That "IT guy" can probably "save" the organization $15k over a year, which he obviously makes very clear to his superiors which is technically true, they don't have to call the contractor nearly as often because "that guy from HR" knows about computers.

That is, until things go wrong. Then suddenly, the $15,000 savings last year becomes a mandatory $50,000 PCI or HIPAA (or whatever your regulation is) audit or a huge fine from Microsoft or Adobe. The issues still have to be fixed because the number of 'fixes' accumulates and you're dealing with an extra 100 systems that have never been updated, no patch management etc. That could easily cost $15,000 if not more depending on licensing costs.

Say it with me: Hashing is not Encryption. Hashing is not Encryption. Hashing is not Encryption.

Very high level:
Hashing is the irreversible mapping of a set of bits onto a (usually smaller) set of bits in order to obfuscate the original set of bits (one-way)
Encryption is the mapping of a set of bits onto another equally sized set of bits where the mapping is reversible through some process (two-way)

Hashing can be done with salts so that using rainbow tables is harder or impossible, but there will always be another set of bits that maps into the same set of bits. It's good enough for hiding a password or for reducing the complexity of finding matches. If you were writing a file system you could use it to do things like de-duplication but when you have a collision, you should ideally still do a bit-by-bit check when a collision occurs.

Calculating a collision with actual useful content - if I want to insert a "return 0" on a particular line somewhere in the Linux kernel) is still as hard if not impossible to do as before without also inserting a load of weird, binary comments. We just know that these collisions can now be calculated faster, but it's not like adding an arbitrary string will break the calculation and produce a predefined hash.

If someone checked in, that means they have permissions to do so. It's not like Git just blindly accepts commits with the same hash but different contents. We know it's possible, it's even possible with SHA256 to create a collision, as long as you're making a hash, you can create a collision as you're mapping an infinite set of bits onto a finite set of bits, there will always be a second set of bits that creates a collision as the number of sets approaches infinity regardless of the hash function you use.

The fact that it's "easier" for a certain definition of "easy" doesn't mean the thing is broken, it just means people should be more careful when accepting particular hashes (eg. if you're using a cloned repo of whatever software you want to use) but even then, a bit-by-bit comparison can easily weed them out.

As far as mainstream repo's a) you would notice someone suddenly inserting a very oddly shaped document into your repo's b) that person would require permission to do so and c) you should never automate a repo to pull in and compile something into production. Not sure if that's what happened here, the summary is very unclear as to what actually happened besides someone intentionally pushing a broken thing and it broke other things.

Depends on your definition of feminism indeed. I'm taking the current "modern" feminists (third wave feminism) which you can see in action on Twitter (eg. the GamerGate instigators). Relying on the dictionary definition of a feminist depends largely on your dictionary and your area, some still say it's about equality between the sexes, more modern definitions leave the equality out of it.

A traditional feminist movement in modern eras would be primarily focused on countries around the world where women don't have the rights yet to run for president, dress how they want or drive a car (or go to school for that matter), but that appears to be lost on modern feminists.

Obviously if you disagree with the definition that these are hate groups, you could just be a part of it and not see the issue of what your group represents (eg. if your definition of feminism comes from AmiMojo or PopeRatzo on these forums) which is the same perspective as being a member of the KKK, they don't see the issue either.

I thought exactly the same too. And I've spent years hanging my life (and other people) off "self-driving bolts" driven into limestone cliffs etc.

The "self-driving" designation, for Hilti, at least, refers to "in this package are a combination of hole-cutting bit and permanent anchor" ; you're still expected to supply the power (elbow grease), holding tool (a sort of cold chisel body), and final connector (which threads into the bolt, and has a head of your choice for your application).

Actually, Hilti still supply the final connectors, but not the single-use bits. And I can understand why. They take real care from the end-user.

Non-exclusive doesn't mean anyone can get a franchise agreement. The problem is that even with massive complaints, the exclusivity agreements remain in effect. It's simply impossible for any other provider to get an agreement with the same terms TWC gets. And though technically illegal, NY courts only allow for local arbitration of said contracts which are adjudicated by local politicians. By the time this is even permitted to go to a non-local judge you spent a good 10 years in court.

Just because something is mainstream vs fringe doesn't make it any more moral. Feminism and Christianity is relatively mainstream as is BLM but that doesn't make them any less dangerous, hate-groupy or morally superior to the KKK or Black Panthers which both are having a resurgence due to the former. Nazis were pretty mainstream, it was just those crazy SS and Hitlerjugend that were fringe by that definition.

In reality, there was probably a set of reasons more like
(1) we've decided to use these chips because they're cheap and promised to be available for shipping in 8 weeks ; here are prototypes.
(2) Software Div. needs to write this sort of data in 32bit words and read this in 64bit words. So we'll do that.
(3) Testing called on Friday about last week's version ; on memory block #4 they get errors because the readout isn't fast enough, so if we mirror that to here we can do interlaced async reads and get 30% better readout rate. So have that ready for Wednesday. And Software want blocks #6 and #8 to be 32bit ROM words but block #7 to be 64bit RAM.
(4) the chip fabbers say they should get 3% higher bus stability, but we don't have time to deal with that and we'll assume the production chips will be as unstable as the preproduction examples we've got. Get to it!

f I actually wanted any of the extra benefits like medical. I don't go to the doctor in the last 5 years, because I have too much work to do.

At least one person in this exchange doesn't understand the meaning of "insurance", and I spent a year at college doing Statistics with second highest exam results for the year.

Which is understandable, I suppose, if you have "free at the point of use" healthcare which is paid for through general taxation ; you may mistake the medical premiums as being "payment for the doctor", while in fact they're a fixed fee for there being a doctor (hospital, MRI, oncologist, whatever) to call. You know how your car insurance covers claims over a certain amount (the "excess", in our terminology ; yours may differ, but the concept will be there) ; well your medical insurance does similarly, but with a more complex list of exclusions.

Creating such an artificial environment in space "from scratch" may be much harder, than using the readily-made planet.

Do you have any idea of the gigatonnages of material needed to terraform a planet like Mars to Everest-summit-at-the south-pole levels?

For Mars, to bring it up to an average atmosphere that is merely lethal (0.1 bar - your tears would boil - followed by your blood) you'd need to deliver around 800kg of suitable gasses per square metre. That's around 2*10^19 kg for the whole planet. Something like 1% of mass of the asteroid belt, if it's as volatile-rich as the gassiest areas seen by Dawn on Vesta.

Essentially, you're going to need to mine most of the asteroid belt for gases to terraform Mars. And you're seriously going to propose that level of exploitation without - as a pure side line - learning how to live in space? Not going to happen.

(Another tiny factor for terraformers to contemplate : Earth surface = 511 million ; adding Mars would get you another 144 million (neglecting any Martian oceans - which I can't envisage you having a vaguely stable environment without), less than 30% of our current land area, or around 2 gigapeople worth.

What benefit are you expecting from terraforming Mars again? Or is it total wish-fulfilment fantasy?

I do say CE / BCE in real life. Whenever we're talking about historical matters at the pub - e.g. with the digger-driver with his collection of locally found stone tools. Or when talking about the several Neolithic to possibly Iron Age burial structures in the area.

Why would you not use the correct terminology? The one thing we can be sure about is that the arrow-knappers and burial-makers were not Cleesian due to this being centuries to millennia before the claimed life of Cleese
