I think it may be an April Fools joke. It is dated for tomorrow. It says in the page source that they sold for $1.1 Billion, but is that real or a joke?
gregpilling··on America Needs Small Apartment Buildings
My 1959 red brick construction house in Tucson, Arizona is built the exact same way, but for heat control in the summer.

I also own a rental house that is 100 years old made of 14" thick mud adobe walls, including the interior walls! Also done for temperature control.

10kg of steel would cost about USD$10.00, and then shipping it around the world costs again. At my factory, we use the number "50 cents a pound" as an average cost for shipping pallets around the lower 48 states.

So your extra 10 kg would cost me about $20 more. At retail that would be another $100 or so. In other words, making it 10kg heavier would sharply increase the price; it would also be for things that aren't easily visible to the consumer. Your competition would destroy you.

Its a sewage treatment plant. He has not had anyone come to his business in 25 years that needed ADA compliance. It is part of the current building code, so that is that. No ADA, no final approval.
gregpilling··on Vacant Homes Are a Global Epidemic, and Paris Is Fighting It with a 60% Tax
it was my friends mistake - the city code was clear but he was not aware of it. He owns a lot of buildings, so he self insures and has done so for 20+ years. This particular building they were making into a new business headquarters, so it was disconnected just -slightly- too long.

There was nothing wrong with the electrical. He was forced to make the 40 year old building ADA compliant, with handicap bathrooms, parking, etc. and a whole other list of requirements that did not apply when the building was built.

So take it as a lesson, not a complaint about code. Also, never shut off utilities if you can help it :)

There is also magnification on the investment with leverage, and it can be a good hedge against inflation.

Condsider a property that costs $1,000,000 which you may be able to finance 75% of. You have $250k invested, but it is the whole value that appreciates. So in a competitive market like Paris, perhaps that $1M house is worth $1.75M in 10 years. Now you have earned $750,000 for your $250,000 investment in 10 years. All the while having something relatively safe, and fun to use.

If it was inflation that caused the increase in home value, then you are covered for that too, much better than keeping cash in a CD or savings account.

gregpilling··on Vacant Homes Are a Global Epidemic, and Paris Is Fighting It with a 60% Tax
this was interesting ---- "There’s now 107,000 vacant homes, representing 7.5% of all residential dwellings in the city according to France’s INSEE. Deputy Mayor Ian Brossat told Le Monde that 40,000 of those vacant homes aren’t even connected to the electrical grid."

So almost 40% don't even have the power turned on? Vacant or abandonded?

As an interesting anecdote to add, I have a close friend who purchased an industrial building in Tucson Arizona. It had been there for 40 years when he purchased it and he took ownership of it and did not turn the electric service on for 7 months while he did some landscaping and stuff outside. Turns out that was a big mistake. The code says that if the electric is off for 6 month plus a day, it has to be brought up to current year code spec. So my friend had to spend 3 years and thousands of dollars to upgrade this industrial building in order to get a permit to use it.

I wonder how many of those Paris housing units could even have their electricity turned on even if they wanted to. Would it pass code? Then do they get taxed 60% of fair market in this scenario? My friend spent well over $50,000 just on electrical upgrades, not to mention the cost of an unusable building for 3 years.

Does anyone know current Paris electric code?

gregpilling··on ‘Story Of Your Life’ Is Not A Time-Travel Story
Today I learned I am a heptopod apparently. I have ideas quite often that I find hard to write out in sentences, so I end up doing a pen sketch/drawing thing with many colors and stick figure drawings with one or two words beside it.

It is usually when I am trying to think through, or explain to someone else, a concept that has many many variables and the ways that they interact. The current "thought" on my desk has 8 panels, with individual sketch things and 4 colors.

Surely I am not the only one who does this? How else can you explain complicated things without writing a whole book?

"I found myself in a meditative state, contemplating the way in which premises and conclusions were interchangeable. There was no direction inherent in the way propositions were connected, no train of thought moving along a particular route; all the components in an act of reasoning were equally powerful, all having identical precedence…Looking at a sentence like this one, I understood why the heptapods had evolved a semasiographic writing system like Heptapod B; it was better suited for a species with a simultaneous mode of consciousness. For them, speech was a bottleneck because it required that one word follow another sequentially. With writing, on the other hand, every mark on a page was visible simultaneously. Why constrain writing with a glottographic straitjacket, demanding that it be just as sequential as speech? It would never occur to them. Semasiographic writing naturally took advantage of the page’s two-dimensionality; instead of doling out morphemes one at a time, it offered an entire page full of them all at once."

That makes me think of this http://www.technovelgy.com/ct/content.asp?Bnum=987 the Lobster Brain from Accelerando

" "Are you a collective or something? A gestalt" "Am -were - Panulirus interruptus, with lexical engine and good mix of parallel hidden level neural stimulation for logical inference of networked data sources. Am was wakened from noise of billion chewing stomachs; product of uploading research technology. Rapidity swallowed expert system, hacked Okhni NT webserver. Swim away! Swim away! Must escape. Will help, you?"

Manfred winces. He feels sorry for the lobsters... Awakening to consciousness in a human-dominated Internet, that must be terribly confusing! There are no points of reference in their ancestry... All they have is a tenuous metacortex of expert systems and an abiding sense of being profoundly out of their depth. (That, and the Moscow Windows NT User Group website - Communist Russia is the only government still running on Microsoft, the central planning apparat being convinced that, if you have to pay for software, it must be worth something.)"

I live in Arizona and I drive through twisters like that all the time. They are a constant feature in the desert. Along with tumbleweeds blowing along, which disintegrate nicely when hit by your car, but would appear as a large solid mass to the autonomous system and probably freak it out (as it should).
gregpilling··on How Bullshitters Not Just Survive But Thrive (2016)
I am the company owner. I had the bizarre experience of net productivity going UP by firing the warehouse manager. Apparently he had the habit of telling the same long-winded story to each of his 8 co-workers, individually.

Once he got done telling them all about the strawberries that were 50 cents a pound underpriced at Safeway, `15 minutes later they could get back to work. He not only wasted his time, but also his co-workers.

Productivity noticeably went up after his departure. Nobody had complained about his time wasting stories until AFTER he left. Somehow they assumed I knew everything but didn't care (bizarre, since I am fairly frugal) .

So as the Boss in this scenario, sometimes it is hard to tell what the truth really is. My staff was trying to be nice, and not cause problems in the workplace. Thus causing a problem in the workplace.

Occasionally I do the Toyota 'stand in a circle' exercise in the factory to get a real sense of how people move around, how they spend their time. It is always surprising how my assumptions are often wrong.

I also watch for the "delegate to peers" routine. If I assigned it to you, I wanted YOU to do it. If I wanted your co-worker to do it, I would have assigned it to THEM.

gregpilling··on Power surge: Chinese electric car battery maker charges for global market
If you consider the Ipad came out in 2011, which was 5 years ago (for a few more days), I would say 5 years. Touchscreen devices make up about half of the global electronics industry, so by extension half of Shenzhen was built to accommodate that.

With a focused agenda, the US could rebuild a supply chain in 5 years if it wanted to. I think it is unlikely to want to however.

gregpilling··on Show HN: Get Well Soon – AI-based online diagnosis
my family doctor is quite happy that patients do research. She says that while some are hypochondriacs who have all the diseases in Google, most of the time it is useful for the patients to have spent some time researching. It saves her explanation time when the patient is informed, and also some edge cases pop up where the patient came in with a good insight.

gregpilling··on Tesla Shock Means Global Gasoline Demand Has All but Peaked
conversion kits did exist for the fuel change. It was mostly about putting in harder valve seats. The lead was a useful lubricant for the valves.

My idea is that the small block Chevy engine is ubiquitous in the hot rodding world, and it is often combined with a Turbo350 transmission. This combo (or one roughly the same shape) has now been built by GM over 100,000,000 times. They hit that milestone in 2011! http://media.gm.com/media/us/en/gm/news.detail.html/content/...

So we take the Remy250 motor, used to propel the Chevy Tahoe Hybrid (I own one), the Remy is small, about the size of the torque converter in the Turbo350 transmission. That leaves the shape of the engine as a shape to fill with lithium batteries, and the rest of the transmission case can hold the inverter. There is enough room, I have measured.

You may only get 50-100 miles, but it could be a drop-in replacement. Since all the mess is self contained in one blob, it is a matter of yanking the old stuff out and shoving the new stuff in. Basic hot rodding, being done since the automobile was invented.

If it could retail for $20,000 to $25,000 the aftermarket industry would eat it up. I am a SEMA member for 12 years, so I know.

Any VC want to fund this idea? I have most of the pieces pulled together, just need to pay for some engineering time.

gregpilling··on MakerBot's bold bet that 3D printers would become common
So why doesn't the big machine actually print something larger? I have a Haas Mini Mill, which has a 16x12x10 inch work volume, and that is small a lot of times.

I would buy the $69000 version in a heartbeat (we are a manufacturing company) if it would print a 12x12x12 inch size or a little larger

gregpilling··on MakerBot's bold bet that 3D printers would become common
I am looking at your machines now. I can't seem to understannd why your smaller machine is $3500 and the slightly larger one with manual laser scan is $69,000. Its not like the laser scan is controlling the machine, and adjusting printing in real time.

20x price change. If I just want to print in Onyx material, there seems to be no point in the more expensive machine. The carbon filament printing is cool, and I may step up to the $13,000 machine. I just wish someone could justify the big machine - or in reality I wish it was actually significantly bigger. Double each dimension, so 6x the build volume of the small machine. It is using linear guides, it is easy to purchase them in any size needed.

The pricing seems to be arbitrarily aimed at maximum cash extraction from the customer, not reality. I will probably end up with the cheaper machine. I am looking for a way to print parts I would normally machine from aluminum.

It is a well built machine, however. It makes very very nice out of the box prints too. Retail quality, probably the first machine that I have seen using filaments that can do that (in the pro-sumer price range, excluding big dollar machines). It will be machines like this one with good parts inside (slides, bearings, servos) that will make 3D printing really useful.

At the tradeshow I saw the machine at (SEMASHOW) , the side by side comparison to the machined aluminum parts was quite impressive. The part felt like half the weight, and had really nice surface finish.

I agree with the idea that we are 20 years away from a walking talking robot. One that could find the fridge, figure out which mayo is the good one, and which mayo has gone bad. The get the right ham, not the crap the kids like, and find the knives. Where are all the knives? And then put the stuff away, so nobody complains later....

I own 2 welding robots.(Miller-Panasonic Prefab Welding Cell) They are time consuming to program, and you do have to 'touch up' the program all the time. They are both 7 axis machines, with the capability of running another 13 axis each. The complexity of a setup is much much higher than a self driving car, which has go/stop/left/right as possible inputs. A self drive car is only 2 axis of movement.

In order to deal with 900 types of sandwiches in another factory, humans are used, not machines . http://www.mirror.co.uk/news/uk-news/sandwich-factory-worker... . They don't do it because they like paying humans. It is too complex to handle the high mix of products (900 sandwich types) for automation.

gregpilling··on Wazer introduces the first desktop water-jet cutter
For anyone who needs things waterjet cut (or other methods) there are a lot of metal fab shops out there, and you can get things cut cheap enough. The last water jet job I had done in a 24 hour rush was $140 for a 1 sq ft piece of aluminum 1/4" thick. It was shaped with a couple holes in it, not complex, but $140 is a long way from $6000.

For speed, this thing is slow (fine for hobby use) and you may find that other processes are more appropriate - especially if you cut a lot. I have a HD Plasma that can cut 1/4" steel plate at 282 inches per minute; compare that to the 0.4" on this machine. While my machine was $60,000 and thus 10x more money, it does cut 700x faster ..... and I am going to the Fabtech show in Vegas this week because I need to go even -faster- . http://www.fabtechexpo.com/

Same danger. A personal water jet will cut your finger off just like a bandsaw. If it can cut metal, it can certainly cut YOU!
