Remus Project Brings Transparent High Availability To Xen

spotter Re:Nope (137 comments)

the remus paper references vmware's high availibility. (also was published in 2008 about 1.5 years ago, though dont know when it first started to be used, possibly before then)

however, incremental checkpoint precedes both. See (pulling from my bibtex for paper I helped write)

author = "J. S. Plank and J. Xu and R. H. B. Netzer",
title = "{Compressed Differences: An Algorithm for Fast
                                Incremental Checkpointing}",

author = {Roberto Gioiosa and Jose Carlos Sancho and Song Jiang and Fabrizio Petrini},
title = "{Transparent, Incremental Checkpointing at Kernel Level: a Foundation for Fault Tolerance for Parallel Computers}",

author = {Ashok Joshi and William Bridge and Juan Loaiza and Tirthankar Lahiri},
title = "{Checkpointing in Oracle}",

author = "Angkul Kongmunvattana and Santipong Tanchatchawal and Nian-Feng Tzeng",
title = "{Coherence-based Coordinated Checkpointing for Software Distributed Shared Memory Systems}",

as well as a paper I was a coauthor on where we continuously checkpointed a regular gnome desktop (along with its file system) and enabled you to restart it at any point in the past.

author = "Oren Laadan and Ricardo Baratto and Dan Phung and Shaya Potter and Jason Nieh",
title = {{DejaView: A Personal Virtual Computer Recorder}},

Nokia Leaks Phone With Full GNU/Linux Distribution

spotter Re:Err, so just like the Pre? (621 comments)

native code applications exist on the pre. the only thing that has to be created via html/javascript is the outer ui of the app. the inner ui can be implemented as a native browser plugin and do whatever native code can do.

furthermore, any language that has dbus bindings, say whatever scripting language you want, can run in the background and communicate with the html/javascript ui that users see.

The Technology Keeping Information Flowing in Iran

spotter article is so wrong (174 comments)

the reporter of that article is an idiot.

Onion Routing was invented at the Naval Research Lab, but it had nothing to do with ships.

If the reporter would have done a cursory reading of http://www.onion-router.net/, which is the page the creators made, the reporter would not have found any mention of ships on the description or summary of what onion routing is.

US Plans To Bulldoze 50 Shrinking Cities

spotter Re:Article mentions Baltimore (806 comments)

The stadium wasn't built by the Orioles. It was built (and owned) by the state, financed by lottery revenue. Though, both they and the Ravens get a sweetheart deal on their stadiums.

11-Year-Old Graduates With Degree In Astrophysics

spotter Re:Two Year Associate's Degree of Liberal Arts (648 comments)

sounds pretty close to the first 2 years of physics at a regular college (2-3 semesters of general physics, depending on what they include, though generally 2), though where I went optics and modern physics were separate courses.

modern physics was fun. optics was a bitch with the PDEs. No more wave equations for me.

Mac Tax, Dell Tax, HP Tax

spotter all these articles ignore one point (858 comments)

Dells, HPs, Lenovos..... they all go on sale for significant discounts.

Do Macs? Not from my experience.

I can buy a souped up T series lenovo laptop for probably around half the price of an equivalent macbook (in the 1250-1500 range vs. 2500-3000 range for the macbook pro.

And one can get features in the T series that apple just doesn't think there's any market for (such as the old T42p I'm currently typing on that had a 15" 4x3 lcd w/ 1600x1200). Try to find any mac that has anything approaching that pixel density.

Buying a mac is like shopping at Macy's and always having to pay their non sale prices. Buying a Dell, HP.... Is like shopping at macy's and knowing that they always have sales and that the non sale price is mostly a joke.

Streaming March Madness On Linux?

spotter Re:Telling the situation and solution? (120 comments)

wrong, they are not encrypting anything. if you can figure out how to get to the streams, they play fine in mplayer, vlc and totem-xine (albiet not totem-gstreamer, as no support for windows media audio v3).

and yes, I have figured out how to get to the streams. someone even posted my setup to this thread already.

Streaming March Madness On Linux?

spotter Re:reverse engineer their website (120 comments)

and yes, I mean to be a bit obtuse about this. sorry. not hiding it, just not advertising it either.

When my cable modem comes back up, I'm hoping to see if I can figure out how to get the HQ streams working, the streams I'm getting right now are viewable and smooth, but crappy resolution wise.

Collaborative Academic Writing Software?

spotter Re:Is LaTeX worth it for humanities/soc. sciences? (328 comments)

autocorrect doesn't help you if you change the name. yes, you can now search and replace it, but all these things are more prone to error.

I'm not against Word. i use it a lot (heck, I'd rather do my resume in it than in Latex). However, for regular paper writing, its so much easier. Honestly, any paper writing system that requires the use of a mouse is going to make a lot of people significantly less efficient, i.e. in latex all I have to do is \cite{tag}, to make a footnote, in word, I'd have to take my hands off the keyboard, go into a menu and search for the proper reference (or perhaps type it in. But for most people this is back and forth mouse to keyboard.

but then again, I'm one of those people that likes thinkpad keyboards and disables the trackpad, for the same reason, keep my hands on the keyboard.

Collaborative Academic Writing Software?

spotter Re:Is LaTeX worth it for humanities/soc. sciences? (328 comments)

uh. any thing you can use to make a figure for word you can use for latex.

latex can include, eps, png, pdf, gif..... as figures. All word is doing is embedding some image, and generally any program that generates that image can also save it to a file.

I honestly find using latex to be much much easier than word, just because there's much less stuff to get in my way. Also, the ability to macroize things (i.e. type \rlcn{} for really long chemical name) makes life much easier and less error prone to typos.

An Early Look At New Features In OpenOffice.org 3.1

spotter Re:Needs Table of Authorities Functionality (260 comments)

http://cmchoatelaw.wordpress.com/2008/10/29/table-of-authorities-and-openoffice-how-to/

while not as "simple" as word, word isn't really that simple either, and the majority of the additional effort here is an initial setup that doesn't have to be repeated, at least if one makes the effort to script it. The hardest part then is tagging which one has to do in word as well. basically, I think this is solvable without major programming skill, just some macro programming.
