Well because they were making darn good hardware. I had my T60 for many many years. Carbon X1 seems nice.

Now I ended up buying a cheap ASUS Chromebook for traveling, replaced drive with a large one and installed Ubuntu. But still haven't decided if I want to replace my main machine.

Was eyeing Carbon X1 models for a while, but now will have to rethink.

Besides, like some people here, I always wipe everyone out and reinstall my own distro on it (Ubuntu usually).

IMHO, calculating an average is something every teacher should have to do many times throughout their career (at the very least for calculating how well individual students performed on a test relative to their peers).

Calculating an average is the statistical equivalent of 2 + 2. Who could respect a teacher who had to look up the algorithm for 2 + 2 every time they were asked to compute it?

Bullshit. You're mumbling when I can't understand you. Calling it "data compression" is polishing an indecipherable turd.

Of course people make their language more efficient when using common words and phrases. "D'ja do it?" "Yeah." "K." "No prob."

But that's not mumbling.

I think of mumbling as generally being an expressed disinterest in being understood. Sometimes because the speaker doesn't understand what they're being asked to speak about, sometimes because they're shy and insecure about their words. Sometimes mumbling is a way to express derision or disinterest in the information or the person someone's speaking to. Lots of reasons.

Not clever. Kind of the opposite of clever. It's a time-waster compared to just flat-out saying "I don't know" or "I'm not sure" or "I don't care" or whatever.
This seems offtopic unless you think the recent security lapse was some type of conspiracy instead of just apathy, greed, and incompetence.

The only problem I have with it is that bodies are rarely taken back and therefore contribute to the pollution of the mountain.

A dead human body is "pollution"? I guess you can counting the clothing and equipment as pollution or trash, but I would call a dead human body quite "natural".

Yes, it was only installed on their consumer oriented machines. Their T model Thinkpad don't have it installed.

Now the question is of course what else are they installing and what other yet undiscovered issues we'll find. It sounds like FUD but so far based on their response, they seem either incompetent (stupid) or malicious. And I don't exactly like either...

To anyone going to Japan who is reluctant to use AirBnB but still does not want to stay in an "ordinary" hotel, I can recommend going to a Ryokan:

http://en.wikipedia.org/wiki/Ryokan_%28inn%29

Ryokans are Japenese guest houses and can be found in many cities around the country. I once stayed in one close to the Hongo campus of the University and had a fantastic experience. Sleeping in a traditional Japenese room and waking up to a traditional Japanese breakfast before going to the bathhouse or having a walk in the garden is just awesome, even more so because you can do this while being in the center of a city with 11 million inhabitants :D

The verbal portion of the GRE didn't used to involve writing--I haven't taken it in a long time. But some of what I see written by and for teachers makes me wonder how good they are at writing, and at distinguishing good writing from bad.
No 15 years ago Microsoft would have been the ones installing it.

I think Microsoft went from being a hated software giant to sort of an underdog vis-a-vis Google, Facebook, Amazon and Apple.

They are very big and strong no doubt, but I think the attitude they are projecting since switching CEO recently, their open source efforts, and such make them look pretty good PR-wise among the tech crowd.

McGill is not a great university, but it isn't poor either. It doesn't have the pride that Waterloo (our MIT) or Toronto (our... Columbia? Dartmouth? We don't have a Harvard or Yale) has, but it's solidly mid-tier.

And this does not surprise me one bit.

I've met engineers failing out during first year at Waterloo that didn't know the second law of thermodynamics ("why don't we put wind turbines on top of electric cars?") I've met engineers failing out during first year that didn't understand basic units (ie, velocity (m/s) times time(s) equals meters (m = m/ss).

Fuck, I even went to a private school and when a teacher went on maternity leave a history teacher had to teach grade 11 math. After a week I told her I would do it (and I did it) because she couldn't even handle basic, basic y = mx + b stuff, let alone hyperbolas.

The worst part of the whole thing is that Canadian students know* our system is fucked. We have so many immigrants from countries like India and their kids are years ahead of us, but nobody cares! I was screaming about how I hadn't learned anything in math between grade 4 and 8. Nothing. Think about that. We did fraction math for four and a half years. The whole system rewards minimizing absolute failures until around grade 10 or 11. Then people can finally split up into different achievement levels.

It is insane. Also, we underpay our teachers and we don't pay more for math teachers. So for someone like me, I can either earn $200k running a tech company with my Applied Science Bachelors or I can go back to school to get an education degree and earn less than what I earned coming out of university.

This is alarming but not particularly surprising to me, if the culture of education is similar between the US and Canada. Judging by this piece and one I read hear a few days back [1], there may be more similarities than I'd thought.

Ed school for far too many is a compelling choice for people who want a relatively easy college degree. I don't want to diss the countless teachers who choose that route out of genuine passion and love for education and knowledge, but we don't do a whole lot to filter for these people.

And it's an incredible shame, because my brief two year teaching career convinced me that it's one of the most demanding career paths a person could choose. I'm a lead engineer today and was once a startup founder, and neither job comes close to the stress, the emotional demands, the direspect, the time demands, the politics, the motivational skills, and the relationship building teaching required of me.

We act like it's such a big mystery why we have such problems in education. To me it's pretty simple:

1. It's an extremely demanding job that's only becoming more demanding with the constant shifting of accountability (i.e. blame) onto the teachers.

2. Teacher prep is largely horrible. Many ed schools will take anyone with a heartbeat, and highly selective alternative prep programs like Teach For America (of which I am an alum) give people minimal training in comparison.

3. Segregation, poverty, and policy create a situation where the students in the greatest need are the worst-served. This is what really kills our system, because students of privilege often have enough advantages to make out okay even in spite of the first two issues.

No amount of draconian accountability standards, school privatization, or winner-take-all compensation schemes are going to fix these things.

There is some hope though, if we're willing to reach for it. We have a lot of human capital in our education system, but I think we're applying it poorly. Instead of feebly demanding that everyone suddenly become an 10x teacher, we should find better ways to utilize the competent (if not universally brilliant) people we do have. Reduce teaching load and scale back the job to something people can excel at without having to be a martyr.

As a McGill math grad, I must say that it was a running joke in the math department how the Education students didn't really need to know any math (some B. Ed. students shared classes with us during the first year or two). The B. Ed. students freely accepted this joke and were quite self-deprecating about their mathematical skills. Several of them even felt cheated for taking our "advanced" math classes which were, in their opinion, far beyond anything they would ever have to teach in high school or CEGEP.[1]

I guess these jokes had some basis in reality.

[1] Québec has a somewhat outdated education system where the last year of rough equivalents of high school and first year of university in US are done in a somewhat "vocational" college called a CEGEP which is an intermediate step between high school and university. The original purpose of this was to help bring more students into university.
That reminds me when I took one business class during university studies and during the final exam I wrote a formula like:

A * B

D=-------

C

Well, this was rejected by the teacher stating that C should be under B and not A. Oh...
I'm not really sure what your point is. People are making the effort, both experimentally and theoretically. The LHC had some minimal potential to discover supersymmetry, but it has not done so thus far. This does not suffice as a disproof, though, due to the low energy levels. Simultaneously, string theorists have long labored to find more indirect effects that could be detected.

"Make the effort" is like complaining that cancer hasn't been cured because people just haven't tried hard enough. It's one of the hardest intellectual problems the human race has ever faced.

Auto-generating summaries for Medium articles
Thanks for clarifying. It's not obvious enough on the site. Most WP users will be looking for something obvious whilst scanning. It should probably say this on the homepage. I assumed they modified core at first look.
I don't get the argument here. Climbing Everest is dangerous, yes. Launching a rocket is dangerous. Going to the bottom of the ocean is dangerous. Putting your head inside a alligator's mouth is dangerous. Walking a tightrope across two tall buildings is dangerous. Space travel is dangerous. Sometimes, dangerous things should just be left alone by most people, not made impotent so any average person can do them. Danger is part of life.
They do. In fact, there goal is to find fresh college grads who are just good enough to potentially get hired in these firms then send them into the firms as spies.
Look, I understand that this should be a topic of conversation. I have no problem with that. If Québécois feel like the education they are receiving is sub-par then there definitely should be a discussion about it.

But! What I also think is distressing is that, based on this article (and its author) alone, there is also an extreme lack of understanding of statistics. The evidence presented is purely anecdotal. I read the entire article waiting for the author to cite some study or personal research, but that never happened. So, unless there is more compelling evidence out there, maybe the author, McGill students, McGill faculty members, or Québécois (or Canadians in general) should start by gathering some more information before discussing solutions.

One big trouble with small cells is politics.

At least historically the EU has standardized on GSM so you can install one set of small cells that everybody can roam to.

In the US we have long had the CDMA vs GSM divide and we've even had other protocols in use. At the very least you need to support two different protocols in the US.

I think also being a government agency a place like DESY would either let the phone companies put the small cells in for free or maybe even pay a small amount to put them in. (Our neighbors across the street paid about $200 for a Verizon network femtocell so my CDMA phone works if I stand at my mailbox)

On the other hand I think the hotels would expect to get paid to add small cells just like the phone companies pay for tower space for macrocells.
Windows Defender is removing Superfish *and* the cert
The key word is significant. They're not claiming they didn't preload this software for money, they're just saying it wasn't for very much money. Such a small amount of money that they have no problem ending the relationship now that it's causing them problems.

My wild guess would be they got in the ballpark of $0.25 an install.
Sure, but even though it was easy it still required "cracking". In the beginning the secret was not know but in the end the 'adversary' was able to determine the secret. In my mind "cracking" a password or a code refers to uncovering the secret which is exactly what was done in this case. If the password would have been brute forced over a couple of days you would probably call it cracking. The same principle should apply even if you guess the password to be "password" in the first try.
Okay, and how is that significant?

I see you have mentioned TF-IDF as something which you are planning to try. That should be interesting.

The way I see it, (and i may very well be slightly off point)
you have a corpus of 2000 docs
2 lists -> [Wpos] & [Wneg] with count[Wneg] a factor more than count[Wpos]

if you compute a [0-1] normalized tf-idf score for each term in the set [Wpos] & [Wneg] and sum them up for all words in each of those two sets, you get a score proportional to the count of positive words & negative words. Normalized here would mean using relative frequencies, rather than absolute freq. [I prefer calling the latter term counts]

This puts document_word_count based normalization out of picture and makes it implicit in the tf-idf step.

Now you have Two numbers, Sum(Positive normalized TF-IDFs) and Sum(Negative Normalized TF-IDFs) which you can individually normalize for your list sizes, and then use the two scores for sentiment classification.
A dirty hack, and somewhat inefficient if you don't maintain a reverse index.

Second approach could be this.
Use your Word List, both positive and negative, to do a Okapi BM25 scoring against your docs using the list as the query set.
So you would get a BM25score for your docs. and you can use that to define sentiments.

Corpus - D
Di = Document in the corpus you want to classify
Query1 = {set of positive words}
Query2 = {set of negative words}

PositiveScore = BM25(Query1, Di )
NegativeScore = BM25(Query2, Di )

Some Combination to do classification.
if Positive > Negative Score :
call it positive!

Just a thought.
BM25 has some flexibility in tuning it for length normalizations. Check footnote.

PS: There is the British National Corpus too for word frequencies :)

I've wanted to build out this idea for a while now, and finally did while home over the New Year.

I don't have a formal CS degree, and started teaching myself how to code ~18 months ago. It took a while for me to find good learning resources and tutorials along the way (do I learn Django 1.5 or 1.6?!?), and I would bookmark all the good resources that ended up actually being helpful.

I wanted to build a way for everyone to share the helpful tutorials they uncover so that, eventually (hopefully), there can be a place for people to find the top X, most up to date tutorials/resources for learning anything ... as rated by the community.

Would have saved me a heck of a lot of time when along the way. I'd love any feedback on this project!

It's fine to proxy HTTPS.

But when you do so, you assume big responsibilities. You have to do all the stuff the browser does, and even lots of security people, if you sat them down and told them to write everything a browser does, would probably forget a few important things. (The browser security folks are exceptions.)

The top post on this page ('patcheudor) is from a researcher who reports that Superfish wasn't doing proper validation of certs, meaning we didn't even need to extract the private key from the binary to forge www.paypal.com.

If I spun up a stupid fake cert for www.paypal.com last week, with no knowledge of Superfish whatsoever, someone from a Lenovo computer would not get certificate warnings.

The more people look at this, the worse it gets. It's a fractal of bad security.
The public French school boards tend to have lower passing rates in maths and sciences then the public English boards though, chalk it up to the shit-show you need to be allowed to learn in English or whatever else might be at play. But the math and science reforms that Quebec implemented 8 years torpedoed basic math and science proficiency across the board.

I dunno, in elementary schools in the U.S. they start teaching the median by grade 2.

The mean is good when you want an actual expectation value (i.e. how much fast do I lose money when I play this slot machine) but the mean is not the tool to use for characterizing and unknown probability distrbution.
For me the key word is "enhance". Why would Lenovo go to the trouble of bundling this, knowing full well that it doesn't actually enhance anything for end users?
