jayvanguard··on Simple Revision Control
Yeah, I unsubscribed from his blog "Armed and Dangerous." He thinks he thinks he is smarter and more knowledgable about general topics than he really is.

It should be named "Just Enough Knowledge to be Dangerous."

Logic only gets you so far when your base of knowledge is very limited in a subject.

jayvanguard··on Microsoft takes .NET open source and cross-platform
Never in Microsoft's history have they ever followed through on a promise of multi-platform support for their infrastructure. They've tried multiple times but they always end up bailing on it or half-assing it to death.

I wouldn't believe them this time either.

jayvanguard··on Why College Is a Poor Choice for a Lot of People
I agree with this from a CS perspective but I don't think the argument extends to other fields necessarily.

Part of what college gets you and a la cart self-learning doesn't as easily is the confidence that you know what you don't know. That is also why employers prefer a degree. It tells them you have a complete base of knowledge that was well thought out.

The reason this doesn't work in CS is because practice is so far ahead of the academy in most areas. In other fields, such as physics and history this is not the case.

jayvanguard··on Doing Business in Japan
Very well written and balanced, the time was worth it.
jayvanguard··on Leaked Documents Expose Global Companies’ Secret Tax Deals in Luxembourg
I can totally see some CFO getting fired over this. For being NOT on the list.
jayvanguard··on Inflatable baby incubator wins James Dyson Award
So wait, someone created a incubator for start-ups specializing in babies? Why on earth would they go with an inflatable structure instead of a regular office building?
jayvanguard··on How long do GUIDs really need to be?
If you work with large amounts of data it hugely matters. 16 bytes times 1 billion records ends up being way more than 16GB of data, indexes, foreign keys, hot backup, etc. to manage and query.
jayvanguard··on Why the World Is Too Optimistic About China's Economic Future
> he is intelligent

His past record suggests this is debatable. He is very well connected but that is all you can say with certainty.

jayvanguard··on Why the World Is Too Optimistic About China's Economic Future
Shouldn't he be looking at empire level data e.g. the growth of the US economy over the past 100 years, the British Empire in the 1800s, or the Roman Empire at its height.

No-one is saying Singapore or Cambodia is going to be the next world super power so how relevant is it to compare their 5 year growth spurts to what China is undergoing?

jayvanguard··on Yahoo Lays Off 400 Employees In India
Wouldn't that be an offer to apply internally for any open positions rather than a mass move? Meaning 95% of them will find nothing.

It would make no sense to lay off 1000s of people only to encourage them to move somewhere where you have to pay them more money.

jayvanguard··on Should I sign this agreement?
>... this was a particularly uncomfortable and inappropriate conversation to cover through emails and text messages.

I think this is a key lesson. If you're getting into a business relationship you need to be able to dispassionately discuss arrangements and contracts. It is far better to do that via email than verbally.

jayvanguard··on Larry Ellison Will Step Down as CEO of Oracle, Will Remain as CTO
Really? That isn't obvious to me by what Oracle has done over the past 10-15 years.
jayvanguard··on Launching Today: Mathematica Online
This looks like the classic "we don't want to cannibalize our desktop sales" pricing model. Nothing revolutionary here...
jayvanguard··on My experience with using cp to copy 432 million files (39 TB)
It's true. We should have never let the public on the Internet. It has been downhill since then.
jayvanguard··on The Curious Case of iPhone 6+ 1080p Display
Calm down silly-generalization-man. This my surprise you but "iOS developers" aren't a monolith, aren't spoiled, and most have developed for other environments as well. There are more sizes to develop and test for. What was one is now more than one. Fragmentation.
jayvanguard··on Steve Jobs Was a Low-Tech Parent
Re: CEOs tending to limit their kids "screen time" more than the average parent.

A more likely explanation is that CEOs don't see much of their children so they try to exercise control when they are around. Likewise their kids are probably more prone to being out of control since they are less supervised.

That or the article is just based on his confirmation bias.

jayvanguard··on The Curious Case of iPhone 6+ 1080p Display
> I'm sorry you're wrong, different screen-sizes (and resolutions) are NOT market fragmentation. It's not hard to handle them and we've been writing phone and tablet apps for years now, so that's a solved problem.

Yes it is fragmentation. Just because it is "solved", doesn't mean it doesn't create extra work, extra bugs, and from a test matrix perspective, more compromises.

jayvanguard··on The Apple Watch
I thought the motion and immersion were awesome but the graphics were less stellar than I expected. Obviously that is probably the easiest thing to improve. So for first person shooters it could be the best thing ever, but for general purpose gaming I'm not so sure it is worth the hassle (much like 3D).
jayvanguard··on The Apple Watch
I disagree on the watches but agree on VR. A phone in your pocket is really absurd when you think about it. It would be far more useful on your wrist for 80% of what you'd use it for. For the remaining 20% (gaming, typing longer texts, etc.) you can still have a larger phone but it would mostly stay in your bag.

As for VR, there is a solid 30+ years of it being "the next" thing and then failing to be. I tried the Oculus recently and it didn't change my mind.

jayvanguard··on What We Do and Don't Know about Software Development Effort Estimation
> IMHO it is quite easy to make a reliable estimation of well-planned project.

Evidence suggests otherwise. Sure you can estimate +/- 100-200% early on but that isn't what anyone is aiming for in a software project. Even detailed plans of repeatable (non-trivial) software projects do not result error bars that anyone really desires.

jayvanguard··on Gooey: Turn command line programs into GUI applications
Good idea. I wonder if anyone has done this for general unix command-line apps by parsing out the man pages on the fly. It probably wouldn't work for all programs but may be gnu style ones would be consistent enough.
jayvanguard··on Feynman Lectures on Physics now free online
It is awesome how while the page is loading you see stuff like this:

"Now if we multiply Eq. (41.19) by [math], [math]. We want the time average of [math], so let us take the average of the whole equation, and study the three terms. Now what about [math] times the force?"

Soo... am I going to need math skills to understand this stuff?

jayvanguard··on Affinity Designer – Illustrator alternative
> Sketch sucks for drawing

So it isn't just me then. I just downloaded Affinity and within 10 minutes was as productive for core drawing tasks than I am in Sketch. Of course I miss the artboards and would like to see arbitrary export sizes (@0.5x etc.)

Great tool so far. I'm looking forward to using it more.

jayvanguard··on A Conference Stole My Identity
This is a weird case. I can see why he is pissed but you don't have global rights to your name let alone your internet handle. Ask anyone who suddenly finds themselves with the same name as a famous person. Google-slapped!

Should the company have considered this? It is a toss up. If a lone person using an internet handle is the bar to avoid any naming conflicts you're pretty much screwed in coming up with a name for anything.

jayvanguard··on Microsoft To Cut Workforce By 18,000 This Year, ‘Moving Now’ To Cut First 13,000
For those that follow Microsoft and Nokia: does this effectively mean that the acquisition has been a failure? Or was this the plan all along?
jayvanguard··on Higher antioxidant, lower cadmium, and lower pesticide residues in organic crops [pdf]
It looks like it is not a new study but rather a meta-analysis of existing studies:

"Demand for organic foods is partially driven by consumers’ perceptions that they are more nutritious. However, scientific opinion is divided on whether there are significant nutritional differences between organic and non-organic foods, and two recent reviews have concluded that there are no differences. In the present study, we carried out meta-analyses based on 343 peer-reviewed publications that indicate statistically significant and meaningful differences in composition between organic and non-organic crops/crop-based foods."

I assume that is just where he posts some fun throw-away pics.

jayvanguard··on Ask HN: Why are we obsessed with javascript?
Java succeeded with this on the server-side but failed on the browser and desktop side. I'm not sure how to characterize it on the mobile side -- success in core libraries and basic language but not in the UI.

Javascript has finally gotten reasonable on the browser and ok on the server, but mobile Javascript apps aren't much better than Java was/is on the desktop.

jayvanguard··on Rob Pike's Rules of Programming
"Developer time is often more expensive, but it's always a one-off cost."

Bear in mind that opportunity cost is an unrecoverable loss. Game programming where you press a DVD is an exception, but in the majority of areas the greater cost is actually in maintenance.

jayvanguard··on Inspecting Yosemite's Icons
Game Center has always been kind of weird. Is it done in a location other than Cupertino perhaps?
