<p>DVD±RW was super useful for passing around files in a period where flash drives were expensive. My high school photo journalism club used them a lot to pass around photos and documents, a couple days later they'd get ingested into the PC in the club room, erased, and put back on the pile for you to bring one home.<p>I don't ever think I had one fail to write</p>

<p>Hey! I get this is a throwaway account so you might not answer, but I really, really don't like opening an article and having the first thing I see in a thread be someone calling the author a slur. There are ways of expressing insult without bringing intellectual disabilities into the mix.</p>

<p>I had a cholecystectomy a few years ago and had a complication that caused a gallstone to get lodged in my common bile duct after removal. Three days after surgery I was in the ER, I let them know I was in debilitating pain and that I <i>just</i> had surgery. They made me sit in the waiting room for 8 hours and only took me back when a doctor walked passed and noticed I was jaundiced. After his shift ended, the nurse who was watching me overnight while I waited to have an emergency surgery (because the surgeon had already gone home for the day by the time I got triaged) was told to keep an eye on me and do blood draws hourly. I didn't get seen once and by morning my liver enzymes were so high they were off the testing scale.<p>Sure you can go to the ER. The level of treatment you get heavily depends on luck</p>

<p>I used to work in Manhattan, you 100% don't need a car there. A backpack for your stuff.
Subways are a bit faster than walking for short/medium distances, faster if you're going interborough. But cars are so so much slower. Trying to drive in Manhattan traffic is torture.
Maybe you need better walking shoes? Manhattan isn't flat but I wouldn't call it super hilly either. It's mostly level grade, and the sidewalks are for the most part well maintained.</p>

<p>Growing up in the north east, my parents had a solar pool heater (they still do), Heating a pool via thermal collectors meant that we could reasonably use the pool through the end of September / early October some years, and it wouldn't be freezing cold on hot days in June before the water had a chance to warm up naturally.<p>It also had the side effect of keeping the heat off our roof and would actively pull heat out of the attic. PV panels would have worked with a heat pump but probably would have cost a ton more for the required capacity needed. Not to mention the extra heat on the roof from not having it watercooled.</p>

<p>This is a cool laptop but after looking it over I hope ThinkPenguin decides to sell replacement batteries (since they are removable) and perhaps even a higher capacity one that sticks out the back a bit. Also the inclusion of a B key M.2 is great for say, an LTE modem, but the page makes no mention if they wired a SIM card slot up to it. Another thing I wish was an option would be to configure without a wifi module, since not everyone is focused on libre firmware, it'd be nice to throw a generic wifi+bt module in there, rather than have to rely on an external bluetooth dongle. I know I can just swap it out later, but that's sunken cost and e-waste for the built in unit which kind of stinks.<p>EDIT: I checked around their shop, they <i>do</i> sell replacement batteries for $109, but I still wish they sold an extended cell variant like laptops did 10 years ago.</p>

<p>I have a soft spot for sun rays. Back in college I had one set up in my dorm room that I grabbed from a surplus supplier that hooked into the school's servers so I didn't have to go all the way to the computer lab to work on my assignments. (I still have my smart card somewhere)<p>I remember thinking back then (2013) when this tech was getting sunset that we had somehow gone the wrong way, and that thin clients were the future, especially from an efficiency standpoint.<p>I still believe that, but we're still a ways off from general purpose compute accessed over the internet for the majority of use cases.</p>

<p>I've been doing this for years! FYI if you have XFinity or Verizon FiOS you get one end of this for free. All FiOS routers support MoCA, even if you're connected to the ONT with direct attach BaseT (it's used internally for the set top box LAN segment too). Also XFinity Cable modems (at least, the last one I had 2 years ago from them!) supported it too, but not out of the box, it was a hidden option in the settings menu.
Depending on the gear, you could get as much as 2.5Gbps through the channels, but beware! just like WiFi, this is shared bandwidth for every device. Its also a bit sensitive to daisy chained coax splitters -- it prefers a flat topopgraphy for best signal performance (though you should really be doing that anyway). Also unlike WiFi, MoCa is really zero config needed past initial enable.</p>

<p>A decade ago was 2013, the pentium 4 is at least 13 years old now, but entered production 23 years ago. 
There's still a lot of utility to be had from a 10 year old machine. My daily driver laptop os a lenovo t420 which came out in 2011. Sure it can't play games but it'll do fine with youtube, programming, etc.<p>My server box is also a 2012 era machine, it's a 3770k build. It's perfectly fine for what I use it for. 
Yeah it takes a bit more power than a modern intel chip, but it sure beats the alternative of throwing it in a landfill to save a few watts at idle.</p>

<p>Theoretically, if power-to-gas plants can be manufactured at scale, you could make gas generation plants further away from where energy is being consumed. We already have tons of infrastructure on this planet for moving gasoline around.<p>You could also keep ICE engines in use without worrying about their carbon footprint. Excess renewable power turns into fuel to be used in cars, boats, trains (diesel electric freight cars), and airplanes.<p>Using this tech for off peak leveling on the grid might not be cost effective, but it can certainly be used to support the existing infrastructure we have to allow for a more graceful transitional period.</p>

Your numbers are off by a factor of 3600.<p>1TWh / 20 Watt brain = 50,000,000,000 (50 Billion) Hours.<p>50 Billion Hours  / (24h * 365.25) = 5,703,855.8 Years</p>

<p>I (Mostly) agree with you here:<p>> Finding and fixing bugs is a lot of fun. Incidence response is a lot of fun. Hacking on new projects is a lot of fun. Writing unit tests is fun too.<p>I'd agree on the first three, I'm not a huge fan of unit tests though. They seem like something a "good programmer" should do but to me it's in in the CYA lane, not programming.<p>> Refactoring, rewriting, sprint, agile, rearchitecting things etc aren't that fun.<p>I actually like refactoring code. To me it's like pruning a garden, moving stuff around to fit better. It also helps me on longer running projects to fix up crap that I wrote months/years ago. I'm always growing as a developer, and fixing foundations so they don't end up a cobbled mess is actually a pride point for me.<p>Agile / Sprints / Pre-Future proofing / API contract writing? Pure overhead for me. My current job is a ridiculous amount of meetings. I get like 15-20 hours of meetings weekly in my position.<p>This really boils down to being at a company that doesn't have technically knowledgeable management, and being on projects without a dedicated architect.</p>

<p>When you're making 50-70k / year you're probably not able to put money in a 401k, especially in the event you have a single income 3 or 4 person household.<p>This is also missing the point slightly. You shouldn't have to rely on tax day returns.</p>

<p>When I worked in NYC a few years ago, I was living in an apartment on Long Island, the LIRR was 1h30m on average, plus 10 minute drive to get to the train station, plus another 20 minute walk from Penn to 3rd ave where I worked. On rainy days I'd take the subway but there isn't a direct route so I'd have to change at times square so it always ended up taking longer than walking.<p>Easily 2+ hours each way from door to door. And let me tell you, the LIRR is vastly overfilled during peak. You're lucky to get a seat for that 90 minute leg of your trip, and if you didn't, you were probably sardine packed in the aisle.</p>
