I don't understand why a simple problem like password management, needs a subscription and a private company to create software for the problem.

Speaking from recent experience migrating non technical users to 1Password, while something like pass might work well for me/the typical HN user, there's no way I'd try to get family to use it. I have found the overall 1Password user experience to be very friendly and reliable, but am still semi regularly having to help family figure out/re-explain something about how it works. They'd be lost with something like pass.

+1 on the Alton Brown recommendation from others.

A book that we've used a lot for ideas on cooking healthy and cheap meals is "Good and Cheap" by Leanne Brown. You can download the PDF for free from her site, or buy a hardcopy from several sites (I have no affiliation, just a happy buyer/reader/cook):

https://www.leannebrown.com/cookbooks/

It's based on trying to counter this very idea ... and has a lot of great ideas for what feels like "fancy" meals, but with pretty simple ingredients/instructions. Highly recommended if you are interested in expanding your kitchen repertoire (whether you're a cooking newbie or an experienced "foodie").

Funny, I just got a flier from them in the mail today. They recently (not quite 1 year ago) opened a second store in my area, about 20m down the road from another bigger Guitar Center. I thought it was a bit strange that they'd put them so close together.

I had a big robotix kit and loved it. My parents kept it and I was planning to have my kids use it, only to find out a few years ago that none of the motors work anymore, and a lot of the plastic has become brittle, so breaks easily when taking things apart. sigh

I love my Aeropress, but an arguably even simpler option is something like the Hario V60 (http://www.amazon.com/Hario-V60/dp/B000P4D5HG/). $19, and no plastic if that matters to you. I think the filters probably cost you a bit more than the Aeropress.

IMHO you should have several different coffee brewing methods at your disposal :-)

We've done a few blind taste tests at the office between an AeroPress and percolator (and keurig and pour over if we're counting). I suspect it's largely personal preference as the percolator advocate has chosen the percolator brew and I (the AeroPress advocate) choose the AeroPress. To me the percolator has a certain (undesirable) taste profile that always tastes like percolator. Academically I don't like that the percolator keeps "recycling" the water during the brew cycle.

I use a fairly fine grind, although not as fine as I use for espresso. According to the stock AeroPress instructions it should take about 20s to depress the plunger, if it's too hard to press it's too fine, and conversely if it presses with little to no resistance then it's too coarse.

They're pretty close in my book (have been using the AeroPress for ~1 yr and the chemex for a few months). The chemex is a bit easier if I want several cups at a time.

I used fish for about 6 months or so and loved it - with this exception. Initially I'd just hop into bash to do whatever I needed (as another comment suggests), but what was the "last straw" for me was not being to have some of the convenience functions that virtualenvwrapper exposes for working with python virtualenvs. My solution was to switch to zsh/oh-my-zsh - I'm pretty happy with it so far, although I do miss a few things from fish (namely the auto suggest/complete when typing previous commands).

Blackphone 12 years ago

Yeah I wondered the same thing. Needs some clarification - it reads to me like "we plan to be in business for at least 2 years, during which time your phone will work", but leaves me wondering how useful the phone would be if they went out of business.

Wow that seems like a very long time (especially on the cooling side). Using my Turbo Crazy setup (see other comment here), I hit second crack in about 10m (which I'd like to get pushed out to about 12m I think, but the temp control on my convection oven is not very precise). For cooling I dump the beans into a 2 sided perforated oven pan (I can't find an exact link, but imagine 2 of these that attach together: http://www.amazon.com/dp/B002KE5OLY/) and shake it gently over a fan, they're cool in about 2-3 min. I figure on about 15m per half pound of coffee.

FWIW I've never had chaff catch on fire, and it seems to me that my setup is probably cranking a hotter/more direct heat than an oven would.

But yes - roasting in the cold stinks - and yet I still do it as well. :) On the plus side, that cooling time drops to a min or so when it's 30F!

Yes - Sweet Marias is awesome. Their sampler packs are an easy to get started. I usually peruse their latest arrivals and pick a pound or two of several different varieties, based on their cupping notes to get an idea of the expected flavor profile. E.g.

> There's a maltiness in darker roasts, that is like sugar in the raw. The cup is smooth, sweet, and with a touch of malic tartness in the acidity. There is a lactic quality too that reminds me of fresh cream caramel, which plays off flavors of apple juice nicely. At Full City roasts have a juiciness to them with a slight tart note, like cranberry grape juice. The mouthfeel is silky and with a finishing flavor of sweet cocoa. City+ to Full City+.

EDIT: formatting

I've never really thought about this per se, but the first thing that comes to mind is that if things are uneven, it's generally more like some beans are burned and/or some aren't roasted enough. Either of those scenarios are going to produce undesirable flavors. I think the more common way to capitalize on a variety and depth like you mention is to roast different types of beans separately and then mix them. That said, there's a lot of complexity and variety just in single bean (or, single origin) roasts, differing levels of roasting bring out different flavors.

I've been roasting my own beans off and on for several years, the quality is far better than anything you can get at the supermarket and even most coffee shops (unless they are doing their own roasting). Buying green beans is quite a bit cheaper as well, so you get the best coffee possible at the best price - win win!

The air popper in the article is a popular low cost way to get into home roasting, but I started with just a heavy pot and lots of stirring, hard to keep things even. After a short while I built something pretty close to this: http://biobug.org/coffee/turbo-crazy/ Still a lot cheaper than something like the Behmor, but able to easily roast 1/2 lb at a time.

What I love the most about this is the analysis of the roast with opencv, will definitely be trying that for my next roast!

Agree, I've been recharging in infrequently enough that I can't tell you exactly how long I get, but somewhere on the order of 5-6 days I think. I turn it off at night though to save a little extra (I don't need notifications while I'm sleeping).

I bought a Nest thermostat last year and in general have been pretty happy with it. We have 2 HVAC units in our house (upstairs/downstairs), but I've only only bought one for the downstairs primarily b/c of the up front cost. This problem seems to be exacerbated with a smoke alarm where most (or at least a lot of?) people will require multiple smoke alarms. My two-story house should have 3 or 4 detectors to cover all the living/sleeping areas, but even just one detector is enough of an investment to think twice before plunking down $130 per unit vs several of the $7.50 Kidde linked by jeanjq (https://news.ycombinator.com/item?id=6514777). With the thermostat there's at least potential cost savings over time, but that doesn't exist with a smoke detector. Granted, the benefit of potentially saving your life in the event of a fire is priceless, but I think that convincing folks of the value here is going to be harder than with the thermostat.

Also, sensors in any smoke detector "expire" after some length of time (8-10 yrs - http://www.usfa.fema.gov/citizens/home_fire_prev/alarms/), so this is a semi-recurring cost. Also discussed in that article is the type of detection technology. This is using a photo-electric sensor vs a more traditional ionization sensor. Both have their benefits/tradeoffs, the ideal scenario seems to be to include both (slow smoldering fires vs hot and fast). (I've been researching these a bit lately for our house, would happily defer to an actual expert in the field though).

I love (and am tempted by) the technology and polish/ease of use that they've done here, but the cost seems to be more significant when compared to the current alternatives.

Logic Pro X 13 years ago

Yeah, Garage Band is probably the one I've played with the most. I envision myself as a "power user" for most things though (perhaps falsely so!) so I'd like to try something more advanced.

Logic Pro X 13 years ago

As mentioned in another comment (https://news.ycombinator.com/item?id=6052122) I've been considering getting a DAW to hobby shop around with. I've lightly dabbled with several over the years, and am very comfortable on my actual instrument, but am a bit overwhelmed when I look at some of these for doing anything other than just recording and basic mixing/editing (would be nice to build some background/accompanying tracks from some of the synths etc). I think I just need to pick one and dive in to figure out how it all works - are there any resources anyone here can recommend for doing just that? Are the provided tutorials from the DAW vendors sufficient?

Logic Pro X 13 years ago

I think Logic Pro has been at that price point for a year or two? But yeah definitely a lot cheaper than some of the competitors.

Logic Pro X 13 years ago

Indeed - I've been considering getting a DAW to hobby shop with, and have been on the fence between Logic, Ableton Live and Reason.

My (perhaps naive) impression is that Logic seems to be more geared towards recording live music, while Ableton and Reason seem to be more geared towards creating music in the program. They can all do both (recording live and create), but that's just my impression watching their demo videos etc (perhaps describing it as "core strength" vs "geared towards" is more accurate?). I'd love to hear from someone who's actually used one/more of them.

Pretty close yeah, except that serverB is only listening on a private IP, and I want to connect to it in by web browser (http). My primary use case is with hadoop clusters, where I access the jobtracker ui on the public hostname, but when I drill down into task logs it points to private/internal IPs. FoxyProxy allows me to access the private IPs directly/transparently, but I do most of my browsing with Chrome these days, so it'd be nice to just be able to do it all in one browser.

ProxyCommand looks pretty cool though, wasn't aware of it - thanks!

This looks pretty sweet. Seems like it'd work well with EC2 for transparently getting you into the private hostnames without having to open security groups and use something like FoxyProxy. Anyone used it for this?
