Comment Boring Company Real Mission (Score 5, Interesting) 128

Let's talk about the real truth of the Boring Company: it's only a decoy to develop the technology needed in Mars to build the underground cities. Mars doesn't have a magnetic field to protect residents! Go underground is not only one more way to build a city, but also a way to protect life.

Comment Bad Ad placement is NOT == Digital Advertisement (Score 2) 95

So they discovered that were spending for ads in places that they already had a good organic visibility? Many small companies already know that for more than a decade. Congratulations for EBay marketing staff to discover the obvious, they need to tune their ads.

Digital Advertisement is very effective, but you need to use goof analytics to understand what brings results and what is just money drain. Again, this is obvious.

Comment You can get the Flu twice, any other virus too. (Score 1) 55

- 1st: we have less than 1 year of experience and study with this disease to make any scientific affirmation about that. Any scientist that makes this kind of affirmation is not being serious.

- 2nd: You can get the Flu (Influenza Viruses) many times in your life, and any virus that can have mutations (like Covid19) can generate symptoms of a new infection. This is the reality for any virus, since they mutate, like birds flies.

- 3rd: All the respiratory disease have a tendency to mutate and be able to reinfect a host. The correct answer, based in real evidences that every body knows and see in their life, is that is very probable that you can get it again, but a variation of the virus, like any seasonal virus.

- 4th: All depends of how fast the virus mutates, and it seems that this is a virus that can mutate faster enough to be a seasonal disease.

- 5ft: What kind of "specialist" are you consulting? The ones that got a Flu only once in a life time? The ones that knows everything about this new disease in less than 1 year of study? No more questions.

Comment Do not forget the group dosage level! (Score 2) 243

If you read the study, 3 groups, with different levels of dosage, had different symptoms. It's common and necessary to test the vacine with different levels of dose, since is needed to identify which dosage is secure and also is able to generate antibodies.

In the trial, the group with the highest level of dose had more severe symptoms. The groups with a medium dosage had a good response and less severe symptoms. The groups with a low dose had mild symptoms, but also a low level of antibodies, lower than a person that got the real disease.

It's very probable that the group with a medium dosage will be the one to indicate the secure and effective dose of the vacine.

Note that in the past, no vacine trial received public scrutiny like this. Is very important to have a scientific examination and review. Get declarations of people without context is terrible and works only to create clickbait news, not real journalism.

Comment Please fix the title! (Score 1) 218

Is it too much to ask to change the title? The world "destroy" shouldn't be used for an improvement that is actually lower than 10%.

A wrong title shouldn't be in the front page. Clickbait is bad for every body, for the user and the content. Instead of people being discussing the content, everybody is complaining about the title.

We understand that this Apple chips are doing a good job and this chip, used in the transition kit, is just an iPad Pro chip and not the actual that will be used in Macbook pro and iMac in the future. Also people should be discussing how power and thermal efficient they are, since this is the main point to change from intel to their own chips.

Comment Challenging the Myth that Any Scientist Is Good (Score 1) 123

Academic studies, as samples, shows that some Data Scientists are much better than others (the times-10, or x10, scientist). Also shows that average people won't understand the quality of studies, what make them to believe in any kind of article, since they can't cross-check any study. Most of the times they won't even bother to check anything, perhaps the title of the article that they broadcast to show that they know something.

Comment Re:JVM bytecode is being used by many languages! (Score 0) 128

WebAssembly is not native:
"WebAssembly (abbreviated Wasm) is a binary instruction format for a stack-based virtual machine"

WebAssembly is very similar to the JVM bytecode: instructions to a VM.

Is very interesting to see C and C++ compilers to Wasm, allowing code that was meant to run natively to run inside a Web Browser. In my view there's nothing that won't allow Java to be compiled to Wasm. Also will be interesting to see a transpiler from JVM bytecode to Wasm "bytecode".

A VM compliant with Wasm will run it interpreted or with a Just-In-Time (JIT) compiler, like JVM. (Yeas, VMs usually have compilers inside them).

Note that "native" is a definition that is much closer to languages without a VM and without interpreted mode, like C, C++ and Rust. When people are talking about performance of VMs, many JIT compilers produces on the fly native instructions, overwriting interpreted mode and achieving native code performance. Modern JVM is very efficient and fast. Choose a language based in being native or VM dependent is not about performance anymore, is about cost, maintenance, portability and security.

Take a look at https://www.graalvm.org/ that is an official Java Virtual Machine from Oracle that is capable to compile your code to "native instructions" (ahead of time compiler) and also has a hybrid mode, to enable reflections, that runs your code in native instructions with a VM to support "dynamic" calls (and other JVM features). The performance is very interesting, achieving improvement of 30% over JVM Hotpot (the most popular Java VM).

GraalVM is a polyglot VM, that for now supports officially: Java, JavaScript, Python, R, Ruby, LLVM

Comment JVM bytecode is being used by many languages! (Score 0) 128

A .class file is a JVM bytecode file, not a file with Java code! (The oficial name is "Java bytecode" but is an instruction set for the JVM).

A .class file can be produced by other languages than Java, like Kotlin, Groovy, Clojure, Scala, JRuby, Jython, Raku (Perl6), LuaJ, Eta-lang (Haskell).

So the statement is wrong: "Unlike Java, WebAssembly is typically produced as a compilation target from other programming languages like C/C++ and Rust."

Should be: "Like JVM bytecode, WebAssembly is typically produced as a compilation target from other programming languages like C/C++ and Rust."

Comment Re:Woz vs Gates (Score 0) 335

Nothing changed more the society than personal computers.

By the way, the internet only exists because the personal computer revolution happened before the connectivity revolution. Without the personal computer, internet will be only an academic thing.

Woz did that as a "kid" in a garage, not as the most rich man in the world. Bill Gates is a very intelligent, brilliant business man and important figure, but I'm talking about what a "kid" did, someone with only his mind and no money. Also against the industry of the time, where computers were very, very expensive things, and used by a terminal in a mainframe. The world was a much more difficult place to do this changes, to have access to knowledge and resources than today. People don't realise how difficult was to do that in the 70s. Today any kid can have a computer, can access any book, any information. In the 70s, no one had a computer! No one had easy access to all the information needed to build a personal computer, and he did this almost alone.

Even the IBM personal computer was inspired by Woz, once Apple I showed the existence of a huge market for personal computers. Before that IBM and computers were a mainframe thing, only for companies and business men. Without the IBM PC Microsoft won't be what is today! Even MS history depends of Apple I creation.

Woz did the Apple I almost alone and in his head! From the hardware to the software! Even to write the first code to run in this computer was a hard task, since he needed to build this by hand, in paper! An IDE, or a high level programing language, was just something not possible to use!

In other words, now, you and me, have in our hands much more power, information and resources to build an Apple I than anyone in the 70s! A single person did that in the 70s, powered only by his dreams. This changed everything, created a new industry, made internet a viable thing, changing our society, making information something much more accessible.

Just imagine how much wealth, innovation, and research the personal computer made viable!

NOTE: The classical view of a Hero, is about the power that a single person have. Someone that can do something amazing by himself. Not because is easy, not because he has the power, but because is the right thing to do.

Comment For me (iPhone 5) it's working very well. (Score 0) 488

I use iPhone 5, and for me is working very well, no slow down or battery issues. But I disabled many background applications, and have a small amount of applications in notification center. I don't know how 4S is handling that yet. I haven't disabled anything, I just always used almost nothing in notification center. So, yes, I'm using parallax effect (you should use a bigger wallpaper than previously to really see the effect). One thing, what is your device? How can we know if this is a 4/4S issue or is an issue for any device? It is random? It depends of your installed applications? One thing we really know, each device has a strong difference in speed performance and CPU capabilities.
