Actually, they didn't sell hardly any until they started listening to their customers and came out with a USB Windows filesystem compatible iPod. And the 1st gen iPhone was a dismal failure until Apple gave customers what they wanted vis-a-vis 3G, native applications, and carrier subsidies.
umm. The first generation iPhone sold around 6 million units in the first year (at a good profit margin and with Apple getting a cut of subscriber revenue). It was Apple's first phone, and only sold in the US. Dismal failure? No. Was the subsequent model better? Yes.
The iPod was also quite successful (and essentially a market creator) even before Windows support was added, although I don't have any numbers handy to back this up...
What real competition? I must have missed that part of history. Before High speed you had dialup and all the independents had to buy lines from the phone company, the result is that no independent could could offer better terms than the phone company and stay in business.
That really isn't the way it turned out. Before DSL and cable gobbled up most of the dialup market, the vast majority of Internet users were customers of ISPs that did *not* own the lines connecting them to their users. The telcos generally weren't successful ISPs at the consumer level until after dialup began to fade (although many were successful in selling upstream transit to ISPs in addition to phone lines).
AT&T and other are charged by the quantity transfered. This is not correct. AT&T runs a default-free (Tier 1) network. They peer settlement-free (without money changing hands) with all of the other Tier 1 networks. AT&T does not pay any other network for transit.
The only time it costs AT&T more money when customers send/receive more bits is when this traffic causes AT&T to incur direct costs in upgrading their own network or direct costs to upgrade their interconnection with one of their peer networks.
I've experience with HP & Cisco managed switches, resolved some of the most horrible network issues you can think of (Ever seen what happens when a 12 year old little bastard plugs a patch lead into itself? Two words: CASCADING FAILURE.) I've even came up with an improved disaster recovery policy for my current employer, and been sub-contracted to another business based on performance. Three words. Spanning Tree Protocol.
This makes one wonder: Is it possible that it is cost effective for spammers to employ low-cost human labor and that they pipe all these captcha challenges to this set of humans whose sole job is to stare at computer screens with pending captcha challenges and answer them?
(I would imagine that this job would have high turnover:) )
The magic comes in when you have some in-house programming talent and the open source software doesn't do *quite* what you want it to in some particular area (and neither does the commercial alternative).
An organization that is using an open source package has some chance of making a tweak to the application to make that one little piece fit their needs and environment better. An organization using a closed source solution is essentially at the mercy of the software publisher in this regard.
(That isn't to say that there aren't other arguments to be made for why open source software is less advantageous than a comparable commercial package, just wanted to point out that I do think a little bit of magic does exist here.)
I just tried it now on a mac with safari and it works (not with firefox) As far as I can tell the streaming video portion works on a mac but not the downloadable episodes.
FWIW, the expanded FAQ does state that they expect mac support early in 2008.
" Q: Are there plans to support the Macintosh operating system? A: NBC Direct's video playback and security (Digital Rights Management) are built for the Microsoft Windows(TM) operating system. They don't currently run on other systems, such as Apple Macintosh(TM) or Linux(TM). However, if your Apple computer runs on an Intel Core Duo(TM) processor, you can set up Apple's(TM) "Boot Camp" software to install and run Microsoft Windows XP(TM) on your computer along with Mac OS X(TM).
Full Mac support is expected to be available in the first part of 2008. "
A bunch of our cisco gear has a plug for backup power, and we had some DEC equipment years back that did, but they were different plugs and different voltages. If it were standardized, life would be good.
So switch to Redback gear. It can all be powered by telco-standard 48VDC supplies. B-)
Cisco and most (all?) of the other high-performance router/swtich manufacturers have -48V DC power supplies for their equipment. Some of their equipment has only a -48V DC power option, no AC option.
Are you kidding me:) ? In my experience, finding PC servers with -48V DC power supplies is *not* an easy task. Dell used to offer DC supplies (at a couple of different points in the history of their PowerEdge models), but they currently do not offer -48V DC servers.
Sure, there are quite a few no-name PC manufacturers that sell -48V DC supply servers, but just try to get things like on-site service or 4-hour response from them. not going to happen.
You can go with a Sun Netra, HP "cc" series, IBM x3550T -- all of these machines will cost you around $10,000 for a server that has poorer specifications than a $2,500 AC server from a vendor like Dell, HP, etc. About the only other -48V DC option with a vendor that offers good service options that I know of is Rackable Systems -- I'm not sure how much they cost, but they're relatively new/unknown.
Purchasing servers to go in -48V DC facilities, in my experience, causes nothing but headaches!
I flew out of a U.S. airport today on a domestic flight. We were not allowed to carry on any liquids at all, including those purchased inside security, onto the plane. It only took around 10 minutes to get through security mid-day, though.
Your suggestion that one should learn several types of languages is a valuable one.
I do have one nitpick: C is not a functional language. C is an imperative language. LISP is a functional language. Scheme is a functional language. Haskell is a functional language.
Which vendor has OC768 long-haul gear? I'm not aware of anything available for general sale (i.e. outside of the lab and test sties) today that doesn't do 40Gbps (OC-768) without MUXing together 4 10Gbps channels.
Juniper doesn't have OC-768 interfaces today, Cisco only has them on their CRS-1 router, and they are NOT cheap.
The XENPAK is not even the expensive part if you need to carry the signal any significant distance. The 10GigE transponder card that will go on either end of your DWDM system is probably on the order of $100,000. The 10 gigabit Ethernet interface on your router is probably even more expensive (maybe less if you are connecting to a layer 2 device). Plus, there is the cost of the common equipment in the DWDM system, including systems that handle amplification every 100km or so, regeneration after a few amplifications, etc. $10,000 for the XENPAK is chump change compared to the other parts involved if you're running distances over a few kilometers, and looks even more like chump change if you want to multiplex multiple signals on that fiber and need to buy a DWDM system.
It is seriously expensive to carry large amounts of data over a long distance!
Just because you don't click "I Agree" to a license agreement does not mean that the work has no protections under copyright law. Although there is no contract between you and the publisher, what you have purchased is the media and the right to access the copyrighted work on the media -- you can't legally go out and make copies of the game for all your buddies anymore than you can legally make and give away a bunch of copies of a book you have purchased from a bookstore.
Most of those things can be protected in such a way that you can only log in to them from the machines that require the additional authentication factors that the grandparent mentions. So, you may have the passwords to the routers, etc. but you can only log in to the routers from the admin workstations, which you can't get in to.
This is a fair point, but one which I think most CS programs deal with well. Most CS degree programs require one or more "programming languages" classes in which students study and analyze the major language paridigms.
For instance, the languages class that I took as an undergrad CS major not only studied functional, logic, OOP, and imperative languages, but we actually wrote interpreters from scratch for a small language of each type.
I feel that this cirriculum prepared me well to learn both new languages, and even new language paridigms (although almost all languages fit into one of the above categories)
Network bound? I could see this, maybe, if you're booting from the network (but then you're not disk bound anymore).
If you're thinking of things like brining up the ethernet interface, and obtaining configuration data via DHCP, this should be *fast*. Your DHCP server is probably sitting within 50ms of you, and the amount of data and number of exchanges between you and the DHCP server are pretty small.
I think startup time is likely bound mostly by the disk, and probably secondarily by the CPU and data path (bus, etc.).
Well, every mac made since they got rid of the DIN-9 style serial ports has had at least one USB port. USB stands for Universal Serial Bus. It's a serial port!
If you need to interface with legacy serial ports using something like RS-232 with DB9 connectors, you can pick up a cheap Keyspan adapter. I use one of these things *all the time* with my Powerbook to console into routers, switches, and servers. Works like a charm!
I would say that a single machine language instruction would be considered one "line"

Actually, the Cisco CRS has not only 10Gbps interfaces, but also has OC-768 interfaces available (40 Gbps) -- they're not cheap, but if you have the cash, you can buy 'em.

well, if you look at their numbers, it looks like total bitrate.
"Over 500 songs" for 1GB (the number Microsoft is claimng) is 2MB per song. That equates to 500 4 minute songs at 64Kbps total bitrate.
2MB * 8 bytes/bit = 16Mbits = 16,000Kbits per song
16,000Kbits / 64Kbits per second = 250 seconds = 4.1 minutes
