I don't think you can put much blame about systemd on Linus. At least the first search I made on "linus torvalds systemd" was an article reporting a somewhat annoyed comment by Linus regarding the inability of systemd developers to fix their own bugs.

This is an important and worrying epidemic not because of how many infections or deaths there are now, but because of how many there will be by christmas, or in a year's time. Even with strict border controls, I expect that this is going to be all over the place in less than 3 years time, and very likely less if the virus mutates enough to have a greater contagious time for pre-symptomatic individuals. Containment for this virus is incredibly expensive, and spreading the virus around is incredibly cheap.
People just don't get non-linear progression and expansion. Ebola will hit the world hard before it is ready.
Come on, python's got its problems, but forcing you to lay out your program in a naturally readable way to compile isn't one of them.
I wouldn't mind python's indentation quirk so much if it didn't give me bugs when rewriting and transferring code, or if I could use braces (or something else) to indicate program flow. In short, changes in the control structure of the code can require indentation changes that cannot necessarily be determined by the editor:
A copy-paste of code from one place to another will only be easy to do in the case where the surrounding indentation is the same in both places.
When a particular bit of code needs to be surrounded in an IF statement (or a loop), it is necessary to manually re-do the indentation to indicate where the statement starts and stops.
If my editor decides that the default indentation is 2, while the code has a default indentation of 4, there's a chance I could inadvertently alter the program flow by re-indenting a line.
With other languages where structure is specified by non-whitespace, I can tell the editor to re-indent refactored code to accomodate new changes, taking a second or so instead of a minute or so (plus any time taken fixing bugs).
But the point still stands, you don't want to mess around when there's exponential growth at play. With 50 days doubling time, you get to the population of the world in about 2 years.
Like its file sharing predecessor KaZaa, Skype is an overlay peer-to-peer network. There are two types of nodes in this overlay network, ordinary hosts and super nodes (SN). An ordinary host is a Skype application that can be used to place voice calls and send text messages. A super node is an ordinary host’s end-point on the Skype network
Of course, the problem with the Skype system (as it was when that paper was written) is that the decentralised nature of the network means that your video call could be routed through any number of Skype network nodes (i.e. computers) before it arrives at its destination. I think now Microsoft has replaced most of the supernodes with microsoft servers, so replace "any number of Skype network nodes" with "any number of Microsoft servers".
Presumably Tox is doing something similar to going back to the roots of Skype, with maybe a bit more encryption thrown in.
Then I thought, well perhaps designer spends years designing a game with all sorts of clever ideas then copiers use them all a few days after release. I have to ask, though, is this what happens? Surely a game must spend some time before becoming popular enough to copy, during which it builds a following and has first mover advantage.
Flappy bird is certainly not a good example of the ideas being the expensive part. Here's just one example of an earlier game that is similar in nature:
Right. I finally got around to writing an R function to do this, because this problem has cropped up a few times in the past year: getPV <- function(prevalence, sensitivity, specificity){
popnTrue <- prevalence;
popnFalse <- (1-prevalence);
popnTruePos <- popnTrue * sensitivity;
popnFalsePos <- popnFalse * (1 - specificity);
popnTrueNeg <- popnTrue * (1 - sensitivity);
popnFalseNeg <- popnFalse * specificity;
ppv <- popnTruePos / (popnTruePos + popnFalsePos);
npv <- popnFalseNeg / (popnTrueNeg + popnFalseNeg);
return(data.frame(prev = prevalence, sens = sensitivity,
spec = specificity, ppv = ppv, npv = npv)); }
NCI tells me that 4% of the US population are cancer survivors, so I'll use that value for the population prevalence:
So the best they can do for this test, according to the paper, is a 30% positive predictive value -- if this test comes up positive, there's a 30% chance that you actually have cancer (and that's allowing for 2% of "negative" results actually being cancer).
Yay for institute access. Their idea of "approach[ing] 100%" is a little bit loose:
Based on these calculations, the cutoffs for low (0.10), medium (0.25), and high (0.50) thresholds are 1.47 at a sensitivity of 94.8% and a specificity of 54.7%, 1.73 at a sensitivity of 81% and a specificity of 78.7%, and 1.99 at a sensitivity of 62.1% and a specificity of 94%, respectively
I have yet to do the calculations using population prevalence, but I'm going to guess that the positive predictive value of these tests are not particularly high.
For that matter, all of everything constructed by human beings
You might not be terribly surprised to know that our genes (and the genomes of pretty much everything) are also full of bugs. We have a whole raft of deleterious genetic variants in our DNA that are just waiting for the perfect time to activate and say "hey, you know that life thing? I can make it worse." On top of that, we have a few viral genomes in our DNA (possibly some that are still active), and rely on bacteria and mitochondria to provide us with energy required to live.
In other words, defective objects are the rule, not the exception.
p.s. hmm... I've only just realised how much I miss that handy login form that SoylentNews has to deal with accidental AC posts.
We apologise for the inadequacies of our car at high speeds, and are investigating ways to make it even safer. We have designed a flexible partitioning system to take some of the energy from a "car split" incident, and will be implementing it in all new Tesla cars, and retrofitting it to all drivers who want it. Additionally, the car will require that the driver and all passengers are wearing seatbelts when the car is driving at speeds exceeding 70 mph.
Microsoft notes that it worked with multiple international companies to secure its version of the standard.
Ah, yes. Once again, Microsoft has their own special idea about how to extend a standard. Said like a true Microsoft employee (or paraphrased by someone with a strong reporting bias -- it doesn't seem to be phrased in this way in the original Microsoft post about encryption and transparency).
SoylentNews has decided to avoid non-profit status due to the demands it puts on the organisation, so they're now trying to set up as a slightly more normal "we don't actually want to make money" benefit corporation.
An induction cooktop with precise digital temperature control (SI) and a magnetic stirrer would also be great.
A magnetic stirrer on a magnetic induction cooktop would be... interesting.
We have an induction coooktop with digital temperature control (in increments of 10 degrees). It seems to measure the temperature at the induction coil, rather than the temperature of the pot, so things can boil when it's set to 60C. Also, the PWM cycle of the cooktop (as with pretty much every other one I've seen) is far too long at about 0.5Hz (where I'd prefer a cycle of at least 10Hz, and ideally over 100Hz). Further, the power level can't be adjusted as much as I'd like -- I set it to 800W (or 130C, because that seems to be similar) and it's too cold for frying, but 900W (or 140C) is a little bit too hot.
Sure, I wouldn't change away from induction now that I have it, but I expect it'll be a while before we get a replacement cooktop, because I've become a whole lot more aware of the limitations (and possibilities) in the current technology.
And now that Tesla has freed up the patents for their superchargers, you'll be able to plug an electric bike into something that uses that connection and current (not necessarily the Tesla ones). Given that the motorcycle battery packs are much smaller than the car packs, I don't expect that a 2-minute charge to full would be out of the question.
That might almost be quicker than walking up to a cashier and paying money, and certainly would be quicker if you're not the first person in line.
And, of course, they can snoop on American citizens on google and facebook, as well as for all other communications in Great Britain because the Americans are foreigners.
When you have five eyes, and each eye is in a different country, it's quite easy to work around those pesky "no watching yourself" laws.
I feel compelled to tell the world about a more confusing part of NCBI that I'm trying to navigate myself around at the moment: The Transcriptome Shotgun Assembly Sequence Database. Submitting sequences is... a little tricky. Here's a simplification of the process:
Create a BioSample record for the organism that you're submitting data for
Download a sample template tab-delimited file, and fill in arbitrary descriptions about your organism
Upload the template file (using your web browser), and finish the remainder of the BioSample submission process
wait for email confirmation of your BioSample record, after which it will have an "official" ID
Create a BioProject record for your transcriptome assembly project, and link in the BioSample record (I don't think you need to wait for email confirmation to get an ID for that)
Create a Sequence Read Archive (SRA) record for your transcriptome assembly project
Create an experiment record (in the SRA record) for your transcriptome assembly project, one for each different method of sequencing that was used
Get md5 sums of all the raw data files that will be uploaded to NCBI
Create a run record (in the experiment record), and add in the file names and md5 sums of the raw data files
Upload your files to the NCBI servers using an FTP client
Wait for files to be transferred from the NCBI FTP server to the SRA server, after which the run record will get an official run ID
Create a Transcriptome Shotgun Assembly (TSA) record for your transcriptome assembly project, and link in the BioProject and BioSample records, as well as the run IDs from the SRA record
Use a web form to create a metadata file to download to your computer
Use a custom NCBI program to merge the metadata file with your transcriptome assembly
Upload the [large] merged file to NCBI using your web browser
Wait for email confirmation, after which the TSA record will get an official ID
Congratulations, you are now the proud owner of a Transcriptome assembly ID, which you can insert into a single sentence in your research paper: "The transcriptome that was created for use in this study has been uploaded to NCBI (reference ID: GAAA00000000)."
So that's a bit less than $10,000 for 100 cores on a standard issue Dell machine. It's not completely crazy to expect you could increase that to 600 cores without too much extra cash laid down.

Hmm... sorry, I got the wrong base. But I also got my millions and billions muddled up, so it's still about 2 years....

}
NCI tells me that 4% of the US population are cancer survivors, so I'll use that value for the population prevalence:
> prev <- 4 * 0.01;
> sensSpec <- rbind(c(94.8,54.7),c(81,78.7),c(62.1,94)) * 0.01;

prev sens spec ppv npv
1 0.04 0.948 0.547 0.08020305 0.9960546
2 0.04 0.810 0.787 0.13677812 0.9900409
