I'm waiting for them to require headphones that have a special license chip in them. Everyone must have their own set of headphones and no listeners past the license limit for a source. Give it time.
I wish the OpenSUSE project luck getting this figured out.
Maintaining packages in this manner is a lot of work. At the end of the day, most contributors only work on a handful of packages and don't consider the possible breakage of other packages. One or two people end up doing all the cleanup work. This happens in the BSD community all the time. For instance, if you look at the recent issues in FreeBSD when PNG was updated or the new debate about X.org 7.7 coming into the tree. FreeBSD's approach to ports is great when you want up-to-date software, but the maturity found in NetBSD's pkg-src or even OpenBSD's model sounds a bit more like what OpenSUSE is looking for.
I'm not trying to pick on FreeBSD. I use a similar process for MidnightBSD due to limited developer resources. In my case, it usually means I personally have to update packages. That's why we have such outdated versions of Firefox (unbranded of course) and Chrome. Not only do all the other dependancies have to be the right magic versions, but someone has to take the effort to port a rather complex piece of software. Luckily, the Linux folks don't have nearly the trouble as they're a tier 1 platform for most software these days. Still, there are many different choices in linux for near everything and getting your combination to work can be tiresome. Next time you download packages from any open source OS, consider how much work went into that easy experience. Saying thank you can't hurt either.:)
I think the key to doing a mac vs pc comparison is not just to look at the technical specs, but also the form factor. For some people, apple's systems have a superior form factor. They tend to be small computers (exception Mac Pro).
For me, the holy grail mac is a desktop Mac with real drive bays like a Mac Pro but with consumer intel processors and discrete graphics. I want a Mac to play games on and that I can upgrade. Apple doesn't make anything like that. A mac mini has a 2.5" drive bay so it's useless for my needs. I don't want 4 external hard drives on my desk. It ruins the point of a mac mini anyway. The only mac that can hold my iTunes collection and offer me an internal time machine backup disk is a Mac Pro. Thus I have to buy an expensive, outdated workstation. Even with the bump, the Mac Pro is running on a motherboard and design from 2010. It has last generation xeons on the old socket. Most vendors stopped selling workstations, and the ones that do have been selling them with lowend consumer CPUs often times. Apple still makes a somewhat unique, if dated, product. I'm stuck on a first gen mac pro waiting for an upgrade. I've ebay'd new xeons for it and bought a 5700 series radeon graphics card from apple for it. I've added drives and ram. It's been a great machine, but I was really hoping for an E5 and a modern radeon card. It just didn't happen. It IS possible to find a high end alternative to a Mac Pro such as a dell precision workstation or a alienware system that can compete with a mac pro on performance on price. Apple owns the laptop market on quality units, and they get props for the iMac even though the competition has started to heat up in the all in one space (no touch screens for apple), but they fail the lowend desktop and high end workstation race right now.
People who think apple is always the top of the pack fail just as much as the people who think the case, battery life or other elements of an apple laptop are not worth extra money over a consumer toshiba or something.
As for me, I have a tough decision to make on whether I can live with a computer that can house my iTunes collection or buying another antiquated mac pro.
When my former employer started hiring H1B, the government did a check of salaries compared to market values in the area. The other programmers had to get a raise. There are laws about salary, especially for the guy managing an H1B employee which turned out to be me. He also turned out to be one of the best programmers I've worked with.
I used to have strong feelings against the H1B program, but after seeing jobs unfilled at several employers now, sometimes it makes sense.
Modern web applications use ajax. You need to pick a javascript library. Depending on your needs the right answer might be JQuery, Dojo, YUI, Prototype, etc.
If SQL Database: You need to pick an ORM. Most people work with them now. The popular Java solution is hibernate. I'm a big fan of Apache Cayenne. You also need to pick a database. MySQL (or fork) or PostgreSQL are good choices. else if NoSQL pick a NoSQL database, but avoid CouchDB. Hadoop, mongo, cassandra... there's loads of them.
You need to pick a servlet container: Tomcat, Jetty,...
You need to pick a Java web framework: There are hundreds of choices. Spring is the hot thing. There are many unpopular choices that are good like Wicket, Click, etc. It really depends on what you're building and how it can integrate with your ORM or NoSQL database. Click + Cayenne work well together. Wicket + Cayenne do as well. Spring works better with hibernate, etc.
For JSON, SimpleJSON is a good choice.
You also need to decide how you're hosting it. If you think you're going to do cloud computing, plan for it at the beginning of the project. Different providers offer NoSQL and SQL database options you can just use. It may simplify things. You also need to program significantly differently for a cloud environment to keep costs down. More requests mean more money with some. Lowering CPU load or minimizing database queries might matter too.
There isn't one right answer now. Young people use Python, PHP or Ruby. I see a lot of interest in Python. I'm not a big fan, but it's not a terrible language either.
If you think this could take off, sticking to popular software will aid in finding developers later. At work, we have a lot of problems because of our archaic stack of Mod Perl + (Ingres, PostgreSQL, MySQL, BDB and Lucene) + Apache HTTPD + HTML::Mason + DBIx::Class + legacy C apps running on Linux VMs. We're starting to throw in more java projects now. When I say legacy C, I mean pre ANSI C. This stuff was written in the 80s. No one has even heard of Ingres.
I have oddball tastes in Java like Cayenne and Click and I've made successful projects with them, but it won't help you on a resume and it won't be easy to get people that already know the technologies.
As for browsers, don't worry to much. If your site works in Safari or Chrome and Firefox, most people can see it. If you throw in IE9, you've got most things covered. Safari and Chrome both use the WebKit rendering engine, but have different JavaScript engines so you will want to test on both, but they do usually render similarly. Bonus points for old IE or Opera. Most browsers are trying to be standards compliant. If you want to target Opera, avoid Dojo javascript library.
I just looked at this article as my employer uses Debian and Ubuntu heavily and I've been pushing for ZFS on our file servers. There is no mention of ZFS version, the feature set available, or even a link to the source material.
There isn't much mention of how to use ZFS. I happen to know most commands, but I think this article would be difficult for a beginner even though it seems to be targeted at that demographic.
Some sites have a login on the front page. It might be an ajax call. Your front page rule doesn't make sense in all cases.
Plus, I don't think banning session cookies on a site is necessarily a good thing. Sometimes they're used to track users, other times, it's just convenience by the web app framework and not used for anything but managing logins, shopping carts or similar. Intent matters and this law does not take that into account. It has exactly one exception for a shopping cart.
It really depends on the situation. For example, I build packages for my open source project. The computer science department donated 20 machines for use in a cluster while I was there. I could build around 2000 packages in 10 days. After I left the university, I had to do it with my own computing equipment. Today, I can build the same software in about 2 days with my desktop computer. If I were paying for electricity use to run 20 Dell optiplex systems with pentium 4 1.7Ghz-2.0Ghz + IDE disks to the Phenom II X6 1090t with raid 0 IDE + 2 SATA disks I use now, I'd save a lot of money with the new build.
Most people don't do what I do, but I think it does simulate a CPU and disk intensive work load one might see in some business settings. There are times that virutalization can save money on electricity. Of course, the cost for the disk subsystem to pull it off may far outweigh the savings. In my case, it wasn't that bad and I don't use virutalization for the setup. The software is setup to run multiple jobs in parallel.
Back when I ran builds for SPARC, the two sun machines I had used about $30 in power including air conditioning.
I don't think buying new gaming hardware is going to save anything because video cards seem to use more power now. I just bought a 750 watt power supply because I finally upgraded my aging video card and between that, 6 hard drives and my Phenom II, the system was blue screening during gaming. I've also got a mac pro that uses about 300 watts when idle not counting the display. Conversely, my laptop uses about 32 watts (AMD A6 quad core 1.4Ghz) There's a massive difference between what consumers buy and what some of us run.
It's useful for backups. Raid 1 these things and write every computer and tablet in the house backups to it. Of course that assumes the cloud won't take off. Here's a hint, it won't. The problem with cloud computing is comcast and AT&T. The caps limit the usefulness of the cloud.
I haven't counted, but I would bet I have at least 20TB of storage online in my home now. Most of the used space is for open source project work (packages, iso mirrors, cvs backups, etc) and video. I've got 1TB of iTunes content and it's actually legal too. One could actually back up their DVDs with this and view them with set top boxes. It would be great for a TIVO or other DVR type device. I'm sure there are other uses.
It's more useful for business. Everyone uses hard drives for backup now. I'd love 60TB at work (or even 1/3 of that) for backup. Think about NOSQL nodes for example. High def images and video. Storing every math journal ever made (that's a use case at work).
Even more important is that if they get this to actually work quick enough to read, they could make smaller disks that are actually fast enough to feed a modern Intel CPU. I'm almost always disk bound. SSDs can help, but they are so freaking small. Imagine a carefully designed ZFS pool on these things. It would rock.
> You'd think the field of Medicine, with its strong emphasis on ethics, would understand the rational behind an opt-in system of DNA collection for research purposes.
We're not talking about the field of medicine, we're talking about the profit center of medicine, the drug companies. This makes it harder for Pfizer researchers to come out with new useless drugs to grow hair or any number of other things.
For $99, you can buy your own copy of windows. Not only will you have the DVD to do a reinstall, but it will be clean too. Most OEM restore disks put that crap back on the computer.
You value your time? A good desktop can blow away an laptop CPU. I think that will change as we get new AMD and Intel parts as they don't care about performance but rather targeting mobile devices.
For software I build, an older desktop finishes 20 minutes earlier than the laptop. Both are AMD systems. I think you need to qualify what type of software development you do. It doesn't matter much if you write php code or small web apps in any language. Anything of real substance requires some oomph.
I think this really depends on what the server is doing. More cores is actually really good for a web server. Most languages used for web applications don't favor multithreading for a single request. In fact, it often doesn't make sense to do it. But handling 16 requests at the same time for medium to large sites is very useful.
Similarly, for certain types of database use it is better to have multiple cores. Queries run on a distinct core on many RDBMS so as long as there are no locking issues, you can handle more. It's also quite useful with virtualization.
The tivo clause for one. Apple ships DRM and uses EFI. Lock in is part of their ecosystem. It also causes great problems with iPhone and iPad development.
Don't ask yourself why apple switched, ask yourself why the Linux kernel is still GPLv2.
This really depends on your ISP and package. As I have a business class package with static IPs and Comcast delegates them via ARIN, one can see my home address via my IP address.
no they don't. Many people around here make around $30,000 starting salary. I don't think that's a lot of money for a professional field.
If you're trying to use numbers from big cities, consider cost of living. In my case, I live in Ann Arbor, MI. Apartments in remotely decent areas around here cost $900 a month. My first job out of college, I made $15 an hour. It wasn't even salary for the first 9 months. My next employer paid new guys $32,000 a year starting out of college.
Yeah, you can make $100,000 in california but it also costs 60% more to live there too.
I'm not sure that's what it means. My interpretation is that an employee who normally has access to data, can access it without being charged. They tried to claim they hacked into something they had access it. The crime (if any) is what they did with the data. It's certainly copyright infringement and that would have civil implications.
The judge smacked down the common practice of using "hacker" laws against people who happened to use a computer during the course of something else within a narrow window of having authorized access to the resource. This judge had common sense.
Tape is great in a mid to large business setting. The drives are cost prohibitive for anything else. If sony actually makes either the drives cheap or the media cheap it might be doable for the masses. I've got BSD servers to backup on a open source project budget.
Rumored one is the store here in Ann Arbor that I just bought a dishwasher from. it's a shame because it's busy and they're building a stupid cell phone store in the mall. There's already an apple store, radio shack, t-mobile and a slew of booths full of cell phones. It's not going to do well. There's probably at least 30 stores that sell cell phones in this area. We've got two universities and they're all over the place. It's nuts.
My point was that you made an incorrect statement about there only being one vendor who ships a hardware agnostic OS. I was not arguing about Microsoft's position in the market.
You know you're wrong and by belittling any counter examples, you don't prove that you're correct only unwilling to admit that you are wrong. Citing the definition of monopoly doesn't change the fact that we've given you several counter examples to your claim.
Slashdot Mirror
iTunes has them. In fact, they've been adding a lot of content in the last few months from the BBC. Dr. Who, Ab Fab, The IT Crowd, etc.
Actually this might work. With Microsoft and Google selling hardware now, OEM phone vendors need an OS from a company they're not competing against.
I'm waiting for them to require headphones that have a special license chip in them. Everyone must have their own set of headphones and no listeners past the license limit for a source. Give it time.
