PietdeVries··on Backcountry.com sues anyone who uses its namesake
And just in the news:

PietdeVries··on The US nuclear forces’ messaging system finally got rid of its floppy disks
And the downside: you will only have a few technicians that really understand how things work, hiring new ones is next to impossible as teenagers have never seen neither the hardware nor the software that is running on it. It scales terrible to new locations. I recall a few years ago NASA was looking for 286-processors for the Space Shuttle. I cannot imagine your spacecraft is getting safer because of outdated hardware.()

Then again, armies are known to prepare for the previous war. In WW-1 they used trenches and then came the machine-gun and the gas. In WW-2 all soldiers were prepared against gas, the French dug the Maginot line and the Germans just skipped around. Now we have amazing tanks but the next war is online...

() I have to correct myself: NASA was looking for 8086 chips in 2001 - not 286 chips a few years ago. https://www.geek.com/chips/nasa-needs-8086-chips-549867/

PietdeVries··on A recent paper proposes to bring zeppelins back
What would the force of the wind be on a structure 2 km long and 200 meter wide? Just a little breeze will require an amazing force just to keep the thing docked. Think that you have to maneuvre the thing into position...
PietdeVries··on Texas Power Prices Briefly Surpass $9k Amid Scorching Heat
You can shift the solar peak at least by one hour when importing electricity from California is possible... In Europe there are a lot of international power cables that help redistribute power across the region and that seems to work quite well (fingers crossed).
PietdeVries··on Stricken Russian Nuke Sub Crew Prevented ‘Planetary Catastrophe’
Could the fire that the crew fought with their lives indeed have damaged the reactor (and thus have caused the "planetary catastrophe" - I assume that is what the article hints on)?

Or basically, was the reactor designed in such a way that a regular fire could damage it that it would become unstable?

PietdeVries··on Glass discs that can store 360TB and remain intact for billions of years (2016)
What bothers me even more is the precision of time they can keep the data: 13.8 billion years. Not 13.7, not 13.9 - no: they figured out 13.8 exactly. That's fake precision and remarkably close to the current age of the universe...
PietdeVries··on JetBlue has started using facial recognition instead of boarding passes
Is the issue with the private company, or with the centralized/government instead? Suppose I start my own little company - at least on paper - can I submit a request to access this face-recognization database as well?
PietdeVries··on German chemicals giant Bayer victim of year long cyber attack
If only companies/countries/individuals without a scandal or controversy in their history could become a 'victim', the newspapers would be amazingly empty...
PietdeVries··on Heat Your House with a Water Brake Windmill
While the idea is new to me - using friction in a windmill to heat your house - the practical use in Western Europe could be limited. Installing a 12 meter windmill in my backyard is not going to happen... And then efficiency. A heatpump has a COP of around 4 or 5, so every 1 kW into the system results in 4 or 5 kW out. A heatpump uses electricity, which can be generated using a windmill, but also via solar panels. And a heatpump is relatively easy to link to your general central heating system. Now if you'd want to link your water-brake windmill to the central heating I guess it would be a 'different biscuit'. And since the smaller systems generate 3.5 kW with a firm breeze, you need backup. Suppose you'd not use a water-brake but a generator and heatpump; wouldn't the overall system efficiency be better in that situation? Or at least more convenient if you add solar panels in case there's no wind?
PietdeVries··on Man sues feds after being detained for refusing to unlock his phone at airport
"British security/police seem to take their power a bit too far very often"...

And that is the actual problem here as well. At the airport you end up in a "your rights end here" zone. According to the original story, the questioned person had no right to a laywer as he was not arrested. But he was also not free to go. So there you are: stuck between a rock and a hard place... Sure, you have every right not to unlock your phone. But you will go nowhere, miss your flight, your connecting flight, etc. And all the officers just go home when their shift is over and forget your case ever happened...

PietdeVries··on The open-plan office is a terrible, horrible, no good, very bad idea
The thing is that this working-from-home people significantly impact the efficiency of your office. It's a trend (could be the open-office space started it) but resulted in people easily working 2 or more days from home. That implies that any desk you have is empty about 40% of the time. Or: your entire office is not being used for 40%...

So when bosses realised they were throwing money away, they came up with the open office with flex-desks: no-one has a fixed place, you can sit whereever you want. And there are less desks than people.

That can work out quite well (I work in such an office) but it depends greatly on ehtics or rules: no TVs with soccer games, no speaker-phone (but only headset) and rooms available for discussions or phone calls. And there is a general area (quite large) where you can drink your coffee and discuss the soccer matches or Tour de France results...

For me it works, but I can imagine that without the requirements listed above it can be a cumbersome workenvironment.

PietdeVries··on Pwned Passwords in Practice: Real World Examples of Blocking the Worst Passwords
But what is the value-add of this service?

Complex passwords are quite useful if the server gets hacked and someone walks away with the (salted) password hashes. Against brute-forcing passwords at the login screen of an application they don't add much value, other than making it the user quite hard to remember what the password for this particular site could be...

Theoretically, if you block a user ID after say 5 or so invalid logins, almost any bad password from the Have I been P0wned list will prevent you from being hacked. The chance that you pick exactly that password from the 1-million or so list is quite minimal.

So with that in mind, wouldn't this service be something for website owners that don't know how to properly secure the information they control?

PietdeVries··on How Windmills as Wide as Jumbo Jets Are Making Clean Energy Mainstream
"tried" indeed - because according to the wikipedia lemma covering the topic: However, in July 2013, Ecuador's president Rafael Correa's commission on the Yasuni-ITT Initiative's progress, the commission concluded that economic results were insufficient, leading Correa to scrap the plan on August 15, 2013. As of early 2014, campaign groups are still attempting to save Yasuní-ITT from oil activities.
PietdeVries··on Europe’s central banks are starting to replace dollar reserves with the yuan
Well, if wealth is spread more evenly around the globe, this will indeed be good. Less unrest, less war, less refugees. Not sure if it's beneficial for the US as well though - the money flowing to Vietnam/Slovakia/Nigeria, etc has to come from someone...
PietdeVries··on Europe’s central banks are starting to replace dollar reserves with the yuan
Exports of what? iPhones? These are all made in China, and with the dollar dropping against the Yuan, anything the US imports from China (and also from Europe) will be getting more expensive. And with the dollar dropping, bonds in dollars will be less interesting for investors. Basically, the article suggests that where Trump is aiming to MAGA, the entire opposite seems to happen: the rest of the world accellerates where Trump hits the breaks. Take the example of solar panels: what good will this do to the US? It will make solar-companies doing less research as the Chinese competition is gone. It will impact consumers, and the environment. But it will hardly impact the Chinese - their export will be used internally and in Europe.

Edit: yeah - the Europeans make cars... Volkswagen is the second largest in the world, after Toyota. Daimler (Mercedes) is fourth. Apparently, the top-16 based on revenue includes only 3 American companies...

PietdeVries··on Saudi Arabia Gives Citizenship to a Robot
So citizenship for a robot. That implies 'human' rights for the 'thing'. Healthcare, unemployment, etc. It should be allowed to vote I guess? And as citizens cannot have an owner, it is now an independent legal entity? It can go to jail?

So many questions, so little answers...

PietdeVries··on India unveils $2.5B plan to electrify all households by end 2018
More than 40 million households - about a quarter of all in the country - are yet to be electrified and about 300 million of India’s 1.3 billion people are still not hooked up to the grid.

Soo.... The article suggests that there are roughly 4x40 million = 160 million households in the country, and 1.3 billion people. Divide the one by the other and you get an estimate for the household size of roughly 10 people. That seems rather larger to me, also given the fact that large IT cities like Bangalore are growing like crazy - all with one or two people in an appartment, not 10.

Next, getting 40 million households hooked up to the electricity network for 2.5 billion dollar. Dividing again gives 2500 dollar per 40 households or 60 dollar per house. While labor is cheap in India - this is not going to work.

And indeed: 40 million more housholds (or 300 million more Indians with access to electricity) is not going to do the networks much good...

PietdeVries··on CBS's Showtime caught mining crypto-coins in viewers' web browsers
I have heard of malware that does more or less the same: exploit a vulnerability, but patch it as soon as it has access to prevent others from exploiting it too.

While your plan makes sense, I can see a future where there are two big gray-market parties left that use the equipment under their control to attack the other party, and not mine crypto...

PietdeVries··on Robocalls Flooding Your Cellphone? Here’s How to Stop Them
What kilburn is referring to is that the business model that telco's use more or less stimulate this type of calls.

If a telemarketeer has to pay for setting up a call, rather than the end-user for accepting it (no matter how small the charge is), then placing millions of automated calls all over a sudden start costing money to the marketeer.

Think of it: the caller has the will to talk to someone - why should (at least in the past) this someone pay for that? The Euro-zone does it the other way round: you want to talk, you call, you pay.

Either way, in both situations with call volumes going down and people switching to data-type connections you see the price of calling/receiving calls drop sharply and as listed above the money telco's make comes from the data plans.

PietdeVries··on How paywalled sites permit access to visitors from social media sites and apps
With the real news gone, the fake news will no longer seem fake...
PietdeVries··on The .feedback scam
From reading the "reviews" at http://www.stackoverflow.feedback/reviews, I get the feeling the entire .feedback TLD will soon be hosting all kinds of 4chan-alike pages and the owners will have to take the sites down because of the NSFW things that will be posted there...
PietdeVries··on Microdots in the Intercept NSA leaks expose printer serial and timestamp
So I've been strugling a bit with how this went...

She downloaded/retrieved a document, then printed it, then scanned it again and mailed it to The Intercept? Some stories claim she was caught because access to the document was logged, others point to the dots and printer logging. But printing a document and then scanning it again would not make sense, would it?

PietdeVries··on WSJ Ends Google Users' Free Ride, Then Fades in Search Results
Now how would google find the relevant info (and index it) yet at the same time a 'regular' user would be restricted by the paywall? That might be a solution you can implement technically, but will it also work for your users?

If users don't have access to info because it is restricted to paying users, google won't have access either.

PietdeVries··on Trump 'poised to quit Paris climate deal'
you refer to for instance those US Postal service LLV's that do 10 miles to the gallon (converts to 4.3 km per liter)?

PietdeVries··on DHL pilot alleges poor labor practices that are spreading throughout industry
Isn't this exactly the definition of capitalism and what is at the basis of the entire American economy? You can complain that a foreign company is hiring you for what you consider below-par payment, but unless you find a better paying job elsewhere, isn't this what capitalism is all about? Next to that - aren't American companies doing exactly the same? Why does IBM have more employees in India (80.000 I believe) than it has in the US? Not because the weather is so great in Bangalore - because the people work for $3000 per year(!!).
PietdeVries··on Disapproval of FCC regulations a significant blow against privacy protection
For the nerds among us this shouldn't be too hard. A Virtual Private Server can be rented for a few dollars a month. I have seen examples that charge less than $4 for unlimited bandwidth.

Install VPN software on the server and become your own VPN provider. On your home router you can setup a point-to-point VPN connection and you're done - all traffic encrypted and bypassing your local telco.

I assume that network-providers are not included in this legislation though...

PietdeVries··on Most Electronics Being Banned on Certain US-Bound Flights
interestingly, you see airlines moving away from in-flight entertainment screens in the seat in front of you, in favor of BYOD. A logical move: let the clients bring their equipment (they bring it anyway) so you don't have to (install, maintain, spend fuel on, etc.).

Now with airlines actually removing in flight entertainment, flying from the Middle East to New York can be quite a long trip: no laptop to watch a movie, no screen in front of you.

I guess the US will stop banning as soon as one of these policy-makers is on the same flight as a few bored kids ;-)

PietdeVries··on They Used To Last 50 Years
Could it be that the lifespan of a appliance is shortened because it his to be more energy-efficient? The old fridges (and car-engines, or antything) were not very economic. A few decades ago getting 10 km per liter of petrol was more or less standard. Now the engine with the same cilinders (1.6 liter for instance) easily get as much as 20 km for the same liter of petrol. The engine is highly optimized by cutting away all the heavy parts and replacing it with lighter ones, adding electronics and more moving parts, etc. This optimization is best seen in F1 racing, where the same 1.6 liter engine can deliver as much as 750 bhp.

Now the more you optimize, the closer you get to the boundaries of what the materials can handle. You squeeze out all the buffers, all the extra's. And quite likely, all these buffers made the device last longer but at the cost of running inefficient. So the fridge that the OP talks about - the one running for 50 years - will have used much more electricity than the ones you could have replaced it with. Likely, the lower energy consumption of the device will have paid back the investment in 7 years.

PietdeVries··on German institute successfully tests underwater energy storage sphere
The biggest issue I see is that the scientists specify a depth of 700 meters for the 30 meter sphere to hold 20 MWh. No where near Germany the sea is 700 meters deep. You will likely have to go all the way to Norway to find a suitable sea - with all cable losses and maintenance issues with it. Ah - and that's another thing: how do you maintain a generator on a depth of 700 meters? Isn't pumped storage on land a more feasible alternative?
PietdeVries··on Former Norway PM held at Washington airport over 2014 visit to Iran
You are aware that getting a new, clean passport without any trace of his visit to Iran would have cost him less than the efforts of going through, say, getting an ESTA in place?

If customs is triggered by what countries one has visited in the past, know that only someone who has means no harm has these in his or her passport. All others will remove this evidence prior to flying...
