As I understand it, one of the difficult problems on Windows is the file locking semantics. When a library is loaded in memory it cannot be replaced on disk. So updates require a reboot to put new files into place. This might be the cause of the effect you describe (administrator being unable to delete files).

It has been about ten years since I maintained some Windows installation packages for a reasonably large project (originally built with a proprietary package builder when I took it over from the previous maintainer and then I ported it to build using a fork of the Python MSI builder). So my understanding of Windows package management and the pains of making things work reasonably is weak and out of date. So take this guess with a grain of salt. I might even be describing what happens and why wrong I dunno...I avoid working on Windows as much as possible, so my ignorance is high.

I can really only speak to the comparison of OneGet to apt or yum, which is absurd on its face. And, I have observed the interesting level of denial that kicks in whenever criticism is leveled at an OS based on weak package management. There's always a lot of "well, I just do this ridiculously unwieldy thing and pretend like it isn't a ridiculous and unwieldy thing to do, so I don't see why I would want something like apt or yum". This tread has been no exception. It's like I'm insulting them personally when I say the workflow they are having inflicted on them by their OS is suboptimal.

I just meant iostream. std::strings work fine with cstdio via std::string::c_str(). (e.g. printf("%s\n", some_string.c_str() works fine).

That said, I tend to avoid std::string as well, due to other performance issues (you tend to have a lot of copies and lots of heap allocations you don't really need). That said, I work in game development, and don't have to do much string processing, and someone in another domain might find this more painful than I do.

Aye, there's the rub of course. I can saturate a gigabit port, but sadly my DSL cannot.

I appreciate the offer though; I'm sure if we really put our heads together we could make it work. Might be better for you to talk to IA though, rather than Archive Team. Pop in one Friday afternoon or send them an email.

Archive Team is a very loose confederation of folk who get angry when a website full of user-created content goes offline. We like to say that our primary virtues are rage, paranoia, and kleptomania, and backing up IA comes under the headings of paranoia and whimsy (an optional virtue) more than anything else.

IA is solid; they're not a startup to be acqui-hired, they're not Yahoo. We have time here for volunteers to step forward, each with a chunk of disk space and a desire to help out. We have time to invent something neat that can grow into a different way of doing things. In fact, we have time to do this in several different ways, all running parallel; I want to work on IPFS next.

I've learned git first and found Mercurial hard to use.

I've somehow created a branch that couldn't be deleted. Instead of being really deleted it appeared in remote repository as some kind of a "tombstone".

I've tried to rebase, but to do that I had to fiddle with settings and enable plugins.

My impression was that Mercurial is a higher-level version of git, with the sugary layer doing things that I don't want.

Probably because it doesn't feed into the narrative he's trying to make.

Nintendo have been pretty much been releasing highly memorable and praised games year-on-year. Most of which have a big designer behind it or at least providing advice, whether it's Miyamoto, Sakurai, Aonuma or whoever.

But of course, times are changing. These people have been in the industry for decades. A new generation will need to take its place so they'll gradually move into coaching roles to pass on their knowledge and experiences.

Also, most games developed by large companies are hardly ever attributed to a single person. It's a lot more collaborative now as studios get bigger and more people are involved compared to back then (where most well-known designers got their popularity from) when it was couple of developers writing assembly.
In this context it's cache poisoning that does require breaking the hash. Which is not a realistic reason to reject the concept.

James Mickens is a crazy productive/smart dude.
The word I'm hearing is that this is going to start being the new normal for tech companies.

The market is starting to demand that companies that have huge multiples start to earn their multiples.

FB, GOOG, MSFT, APPL and CSCO are proabably all ok as they can hit their targets with relative ease and don't carry a burdensome multipel, but hype based companies like TWTR, LNKD and others are about to be in a world of hurt, I wouldn't want to be a shareholder in any of those companies:(

This is probably going to be especially painful for the SAAS companies that just IPO'd, I don't think they'll get much time to prove they are worth their multiples and they have the double whammy of coming out of employee lock up periods pretty soon.

AMZN is the one wild card, I would have thought their free pass expired long ago but they are the sole exception that I can think of.

EDIT to respond to the question about FB's multiple, Most people still believe that FB has the ability to turn on a switch and make more money, ie they are artificially making less than they could fro the sake of growth, just like AMZN.
Lyft penalizes you $5 for cancelled rides after some amount of time, at least in SF. Also when the app makes a request on its own and you're not there.

Help Free PACER in San Francisco and New York This Friday
So taking into account these two facts:

> in 2014, it was 51,000 drivers and 2.2 million monthly rides, according to the document

> A ride booked in San Francisco through the Classic service generates a 92-cent profit for Lyft, including marketing costs but excluding corporate expenses, such as software developers and office space.

and assuming that all these 26.4 rides where Lyft Classic(which is of course foolish, but good for now), they would have around $24.28M for corporate expenses. Well and office in SF with ~500 people and all these perks in the heart of Mission district, makes me wonder if they are even profitable...

I can't say I'm entirely disappointed to see LinkedIn doing poorly. They do shady things with their data[1], and I'm not okay with that.

I like the idea, but it feels like they are a company that could have done well and been fine privately, but market pressure forces them into some questionable practices (but I have no idea how representative of reality that is).

1: Such as determining a second email address of mine through data mining or some other method and sending emails to it asking if I know a person, even through I'm already linked with them, and that email address does not have a LinkedIn account. That's either an invasion of privacy, or spam, or both.

I miss the days of MASM and Codeview. I used to debug DOS programs in Codeview and could step into and out of code lines and even modify the code. By changing a JE to JNE I was able to bypass the Lotus 123 2.0 protection so it could be installed on a Netware drive instead of just a floppy disk.

GDB/LLDB it is good that Microsoft is open sourcing their debug tools. Microsoft has been struggling with improving Visual Studio and Dotnet, so in open sourcing them or parts of them in CoreCLR, Visual Studio Core, and then GDB/LLDB they are letting open source developers participate in improving them.

Sure it isn't the full version of Visual Studio, I don't expect Microsoft to give away everything but small parts of it. Sometimes less is more, in that the fewer lines of code the smaller the program the faster it runs.

I would like to see an Office Core and SQL Server Core as well if they can.

Useful for corporate users.

The objective was to protect Mojang's IP on the (probably mistaken) idea that if they release the source code it means they lose control over it.

Added to that, my own speculation is that members of the modding community want to keep the barrier to entry for writing mods relatively high, for some reason or another. Some modders, including the brilliant Eloraam (maker of RedPower), want to maintain their own mods as proprietary and obfuscated.

On the other hand, it picked out 6 of the 7 faces in the photo, correctly determined their gender, and (AFAIK) gave reasonable estimates to all of their ages.

That's one of two equally important reasons for language. The other is to easily identify insiders in large communities. A few languages later change their primary use to inter-community communication, but those will then start to splinter into dialects to easily distinguish insiders from outsiders.
Uber is a classic two-sided network [0], like eBay or Craigslist. It is extremely difficult to displace a first-mover advantage. The hundreds of thousands of drivers are set up with Uber and will stick with it unless something new is meaningfully better (and Lyft is currently worse). Same with the users.

I think you can be legitimately critical of Uber's poor business ethics [1], but the sustainability of their current business model looks excellent, at least for each city in which they are established as the first mover.

I always find it interesting to note that nobody ever acuses Apple of being greedy. The typical punching bag on the "greedy bastards" bandwagon are the oil companies. Interestingly enough they operate at gross profit in the order of 7% while Apple is running somewhere around 40%.

Just google "apple profit margin" for that data. Here's a Forbes article on oil companies, including the revelation that the government makes far more money per gallon than the oil companies themselves. Data is a bitch.

I'm betting it's only a matter of time before Microsoft drops Java and switches Minecraft over to C# or some other CLR language (or puts resources into a sequel of sorts that does the same). With that will probably come a visible source (though not necessarily open source unless the world is really lucky) development model.

When Microsoft first acquired Minecraft, I made this prediction rather fearfully, but if Microsoft's embracing of open-source continues (without the extending and extinguishing, preferably), this might end up being a good thing. Kerbal Space Program has proven to be a pretty good example of a Minecraft-scale modding community around a game built heavily on C# (by way of Unity3D), and would be a pretty good case study for this sort of thing.

This might put a damper in existing modding efforts, though (but on the other hand, there are projects like IKVM.NET that implement Java on the .NET CLR, so it's at least hypothetically possible to support existing mods on a hypothetical Minecraft#).
