Comment Re:Jet engines?? (Score 2) 175

IANA aerospace engineer but I got a different feeling from the lillium website and the video they are linking from the top page about the flight of their full scale prototype. There are also graphics showing the engines pointed straight back. They are mounted on tilting flaps so they would be pointed down at low speeds such as in the test flights.

Perhaps it is not really a jet engine but if these compressors are mounted on tilting flaps I would expect them to be facing straight back at cruising speed.

Comment Re:Good luck with Just In Time parts. (Score 1) 126

In 2009 I delivered a supply chain system to a major construction equipment manufacturer. Even one hour of downtime for these machines is very expensive so people would be cannibalizing other machines to make a quick fix. They already had a satellite-based telemetry system in place to predict failures and servicing, and our system checked different warehouses and tried to pick the best choice based on various rules including lead time calculation. This article is talking about something that other companies have already done for years now.

Comment Humans needed but there are some solutions (Score 1) 124

There are some things that will work.
A major provider carries email for a lot of people and can tell if mail is spam if
- the people have no intersecting interests
- they mostly receive it at the same time
- a number of users mark it as spam (nearly all users who regularly mark anything as spam)
Google is obviously doing this and some other for-pay providers too, is my guess. I'd pay for a way to be able to test my email headers against such a service without actually running my email through their servers.

Also, you can hire people to actually read email subject lines and decide whether email is spam. Probably a small number of people could make a huge difference and I'd propose that the cost of such a system could easily be borne by government, or be covered by a very low fee.

As first line of defense, you can make a someone lenient automatic system that blocks out common keywords/patterns in email. This would probably cover 98% of spam and could be tweaked by an end user (for example anything about Trump, CNN, gambling, Gwen Stefani or hot tubs is spam 100% for sure). A central repository for such keywords/patterns could be very useful to end users. Personally I have a number of accounts some of which are old and combined they send me a huge amount of spam, so I am considering what to do about it. The above would be a big help.

Comment But my 2TB SSD Mac rocks (Score 1) 167

Makes me even happier about my recent purchase!
A lot of mac haters and people saying SSD are unreliable, etc. Guess what, even the touch bar is way better than I would have expected based on the flames on Slashdot.

Well I have lost 1 or 2 files in the past on my 2009
MBP 17in which I loved, despite the weight, until the HDD errors started piling up. I use Windows and run some linux servers too. The price was quite high but I configured the best model I could since I expect to get 5-10 years of use out of it. I know 500gb was not enough to hold 5 years of cruft and VMs. This is my first SSD and surprised to hear how brittle people find them, so will do some research and set up some local storage. I remember a video studio that often had HDDs fail so thought SSD would be more reliable.

It would be more useful to me to hear what mac users recommend for backups - a tethered drive set up for time machine? Or one set up as a bootable backup with Carbon Copy Cloner? Or a local linux box and rsync? Ideally I'd like a fine granularity versioned backup that combines these worlds.

Comment Slashdot now antigeek? (Score 1) 115

Pretty amazing the number of highly scored posts promoting autodarwination of own species. In other words voting *against* safety measures for an acknowledged safety issue. Personally I think a flashing fullscreen big red icon that displays in response to broadcast danger signals would be better but seriously traffic accidents from people ultrafocused on data has got to be one of the bigger threats to readers. Personally I have been in some near misses with bikes

Comment How to think in Perl 6 (Score 3, Interesting) 281

I'd like to express my deep, unending thanks for building something that is really wonderful, Perl, and a wonderful community. I made a living with Perl, the first postmodern language of which I am aware, and derived a lot of enjoyment from TMTOWTDI, and contributed back to the community on Perl Monks at the time. It was a lot of fun to meet some of the famous, talented Perl visionaries then. I enjoy thinking in Perl and it has made me stronger.

I'd like to get into Perl 6 which having stolen all the cool stuff from the other languages appears likely to be the most advanced and artistic of all them. At the very least I look forward to being able one day to think in Perl 6.

Can you provide some examples to /. readers about why you like Perl 6, and what dimensions of awesomeness are waiting beyond Python and Javascript? I think you would be a good person to rouse a wakeup call.

That, and if you have a moment, how about a good reason or three (efficiency? creativity? extensibility? ability to suggest further growth? having lots of PhDs?) why Google should promote Perl 6 in-house and support the growth of the Perl 6 language and implementations. Perhaps sponsor completion of the Perl 6 kernel for Jupyter project? How about sponsor some people to document and make accessible free books? What are some Perl 6 initiatives that could use some eyes if not $$?

Comment Re:Computable universe (Score 1) 102

Unfortunately, I may have just solved the Fermi paradox. Either due to system enforcing a hard limit on observers especially if they can talk and corroborate observations, or due to other civilizations / virii trying to grab more processor resources by getting rid of the competition.
It also might mean you can do more cool, magical things if you keep a lid on it.

I hope I'm wrong. :/

That was very cool, thank you.
IANAP but... How to allow very high precision?
Not so bad (except for us) if you
have a feedback to limit the number
of pesky observers.
Also might not be a bad reason for
c and the expansion of the universe, since
our local processor need only worry
about what is in our light cone.
Less even than that if you have mortals
without fast space travel and you occlude
the nearby interesting bits with clouds
and supernovae. Sorry.
How to handle infinite superpositions?
Perhaps we need another system function
that gathers and limits such silliness.
In fundamental CG ray tracing you can trace rays from the observer and the reverse at least.
Also maybe the computer is like a language compiler being bootstrapped and written in the language itself outputs. Then it can use superposition and many worlds internally! :)

Comment Paperwhite fonts (Score 1) 156

The new Bookerly is excellent and I use it or Caecilia if need more weight. However I must say that the font SIZES that are available are awful!!
There are many sizes around 5 or 6 point which is too small. Then only 2 sizes in ordinary size and 2 giant. I would like to have smoothly variable ecmal point scaling like on epub apps. If that is incompatible with low power cpu then let me get fonts from the net, and be able to buy goof ones from the store.
I would pay money for this.
Also I wish it would read zip / cbz amd let me doenload them as well as image files from browser.
  Also I bought an amazon gift card overseas (in a Tokyo convenience store) but amazon.com refused to accept it. I wish they would just listen "shut up and take my money."

Comment Long time happy user (Score 1) 149

Long time linode user, I have two and have been extremely happy with them. Awesome support and community, periodic big free upgrades, continuously improving and adding services. Now you can create a cluster temporarily or ramp up a server and then turn it off, paying just for what you use, it is amazing and the most fun and value I've had. If you want to have your own server just get a linode. As for the ddos, I felt nothing in the two cities I have linodes.
