Ask Slashdot: Is an Open Source .NET Up To the Job?

ljw1004 Re: Why bother? (377 comments)

Ok. Does that mean the full Visual Studio is free as well? Cost is the main hindrance for adoption of it anyway.

Yes it is free. "Visual Studio Community Edition" it's called.

ljw1004 Re:Why are critical systems connected to the inter (193 comments)

Why is there critical systems allowed to be in the same network as email?

Email from operations to the shop floor: "Hey Klaus, we've determined that for the following job we need parameters set at P=123.79 and Q=119.11". Klaus prints out out from his email-connected computer. Picks up the printout, walks across to the control computers, and starts typing in the parameters from the printout. Unfortunately he has a typo that causes the entire batch to be not quite up to spec.

Solution: come up with a way for the parameters to be taking precisely from email into production, without the error-prone act of typing them out again.

Node.js Forked By Top Contributors

Noordhuis had not one but TWO responses: (1) as you said he dismissed it as trivial, (2) when someone else nevertheless accepted the change he tried to undo it and chided them publically for bypassing both him and (???forgot alias).

Noordhuis chided someone publically, he got chided back publically, seems about fair.

Physicist Kip Thorne On the Physics of "Interstellar"

ljw1004 Re:You will not go to wormhole today. (289 comments)

Relativity is a description of the geometry of the universe. If you would rather believe in your own personal fantasies instead of one of the most well-supported theories in science, congratulations, you are yet another variety of religious loon.

There are lots of spacetimes that satisfy general relativity and are still pretty goofy. Malament-Hogarth spacetimes, for instance, are ones where you can jump into someone's infinite future. (or more precisely: they're ones with two paths through spacetime, one of which has an infinite duration, the other a finite duration, so if you travel down the "finite" one and your friend travels down the "infinite" one then you'll still be arrive while he's been dead for an eternity).

Windows 10 To Feature Native Support For MKV and FLAC

ljw1004 Re:Rather late (313 comments)

2c per CD? How does that price work out for those of us who keep our definitive backups on AWS or iCloud or OneDrive? And who also would need to pay for a fatter internet connection to get at all the files?

I have no doubt that FLACworks great for the niche who have lots of CDs, lots of hard drives, and who have time and money to spend curating them. But really, if you have kids or emmigrate or whatever, the FLACs are as good as gone when you realize you don't have the time or money you need to keep them useful.

Our computers still support ASCII from 1960. I'm sure that mp3 support won't go away in my lifetime. And copyright terms will expire before even your 2nd generation of lossy recoding happens.

Google Launches Service To Replace Web Ads With Subscriptions

ljw1004 Pop-up ads (319 comments)

The ads are replaced with a small message thanking them for being a contributor. The space where the advert would have been is filled with a pixelated pattern, instead of being removed entirely

Maybe we'll get to see pop-ups with pixelated messages of thanks!

Interviews: Ask Adora Svitak About Education and Women In STEM and Politics

ljw1004 Re:A message to Adora Svitak (155 comments)

At 17 years of age, you do not have enough life experience to say anything of real importance about anything involving the greater issues facing society. Incidentally, What Adults Can Learn From Kids ~ {null}, which is why society would function much more smoothly if the voting age were raised back to 25.

Wow! That's mean. As a 40 year old myself, I've learnt a lot from my and other kids. I wonder whether you, Anonymous Coward, have enough life experience to back up your claims?

Elite: Dangerous Dumps Offline Single-Player

ljw1004 Re:Even Donations Come with Obligations (473 comments)

If it is truly single player why would you need a network connection? If the changes are made centrally then there is no need for an always-on connection: just provide optional updates from time to time.

It sounded to me as if (1) yes they are providing updates from time to time, and that "time to time" is every time you do a commercial transaction. (2) why do they need the network connection? I assume because it was lower-risk for them and their schedule to use the same economy engine than to develop two separate economy engines.

Maybe they discovered that their economic engine felt a bit lackluster unless there are huge numbers of participants (reminds me of Ultima Online) and they wanted to force there to be a higher number of participants, both single-player and multi-player. So they're forcing everyone to contribute to make the economy engine feel more realistic.

Elite: Dangerous Dumps Offline Single-Player

ljw1004 Re:Do they have choise but.... (473 comments)

Does Frontier even have a choise but do refund? Single player was part of contract that backer bought, you can go back later and change contract to your liking.

To be clear: THEY STILL HAVE single-player. The only thing is that single-player requires an online connection, and is done in a galaxy that evolves.

Call me anti-social but I don't like playing with others

??? They said the game would have single-player. Presumably that means "not playing with others". The only thing is that the single-player game will require an online connection and the galaxy will gradually evolve.

Elite: Dangerous Dumps Offline Single-Player

ljw1004 Re:Even Donations Come with Obligations (473 comments)

Now you are going to be sharing the galaxy with immature, adolescent school kids and any unusual features you will ascribe to a human moderator putting them there. It's going to have more similarity to Eve Online than Elite.

Why do you say that? They clearly state that they will have single- and multi-player. And they say that single-player requires an online connection so it gets a gradually evolving galaxy. That sounds more like automatically-downloaded DLC, entirely different from "sharing the galaxy".

Elite: Dangerous Dumps Offline Single-Player

ljw1004 Re:Wow Frontier Sure Can Shovel It (473 comments)

It took a while for me to decode all that marketing speak to figure out that they were canning single player.

How did you get that? What I understood was that single-player still exists, but it requires an internet connection and is in a galaxy that steadily evolves. Here's what they actually said:

it does mean the single player has to connect to the server from time to time, but this has the added advantage that everyone can participate in the activities that can happen in the galaxy

So: their statement is that single player exists, and it's in an evolving galaxy, sort of like implicit/automatic DLC.

ljw1004 Re:"Just pay extra..." (473 comments)

Honestly, your complaints seem totally ridiculous.

I'm in the same boat as you. I paid an initial kickstarter fee. I enjoy seeing screenshots and videos. And when the game comes out then I'll get a copy of it at no extra cost. That's what kickstarter is.

If you're "fatigued" by their requests for more backing? If you're upset that you don't get access to the beta without paying for more money? First world problems, a.k.a. "whining".

Microsoft To Open Source .NET and Take It Cross-Platform

ljw1004 Re:Brutal Load Times (525 comments)

I thought .NET cached its JIT images. Is this mistaken? If not, what's really new in .NET Native?

JIT has to be done very quickly. Therefore it's purely local (method-by-method) rather than cross-method. Also even within a method it only has time to do simple easy optimizations. NGEN is a way to do JIT ahead of time. But it still only uses the same JIT algorithm, i.e. doesn't do heavy-duty optimization.

Also, .NET Native does build-time generation of interop and serialization code. .NET Native uses the VisualC++ compiler backend, benefitting from its long history of optimizations. All this adds up to massive perf benefits - in some apps, 50% cold startup time improvements, 85% reduction in .NET startup costs.

Microsoft To Open Source .NET and Take It Cross-Platform

ljw1004 Re:Brutal Load Times (525 comments)

.NET applications still need read about 1GB of libraries from the disk (only portions are kept in memory). This is why .NET applications are so brutally slow to load. Will this improve?

.NET Native speeds up startup times considerably. The way it works is it compiles your .NET app into native code, does whole-program optimization, and "shakes out" all the bits of the framework that aren't actually even needed by your code. (.NET Native is still under development, and currently available in preview form for store apps)

What's up with no-ip?

Drug halts decline in Alzheimer's disease

ljw1004 ljw1004 writes  |  more than 6 years ago

ljw1004 (764174) writes "Alzheimer's disease: researchers are divided on whether it's caused by "beta amyloid" (a peptide found in alzheimer brains) or by "tau protein" (normally used for cellular scaffolding, but can aggregate of control and destroy neurons). Today in Chicago a new drug has been anounced which stops tau aggregation and appears to have halted alzheimer-related decline in 300 clinical trial patients. Do you have friends or family who appear to be dementing? Here is an online questionnaire, part of one used in the clinical trial to diagnose dementia. (disclosure: I made the online questionnaire, and my father is one of the scientists behind the drug.)"
