I’ve been running urxvt for years and have it pretty much dialed in as I like it with base16 Ocean and a bunch of mostly font-specific options. It works reliably and quickly for me, without any muss or fuss (I run my Openbox without any menubars and the chromeless, super minimal look fits right in).
There’s just one problem. I use nload a lot (bandwidth monitoring tools deserve it’s own writeup one day), and it flickers in urxvt. Now, to be clear, this isn’t a bug with urxvt, which is merely doing what it’s told, but I noticed that this sort of ncurses flicker on clear screen, due to the way it buffers, doesn’t happen in vte-based terminal emulators.
Setting up the fonts and colors was relatively painless and you can even dynamically reload those. The one niggle was that the left scrollbar was much more distracting than in urxvt. A little bit of searching led me to a related issue, which pointed me on ways to update GTK styles. It took a bit of tweaking to get things just right (there was some stray corner rounding that required some creative CSS), but here’s where I ended up with my ~/.config/gtk-3.0/gtk.css:
One thing to note, is that termite is actually a bit slower than urxvt (even ignoring it’s slightly weird refresh – when showing lots of text it tends to buffer and seems to skip rendering things you might see zip by in other terminal emulators), but it does handle mpv --vo tct rendering correctly (whereas my urxvt just barfs). For some more on terminal emulator performance, this alacritty github issue is a good start (alacritty may be hot shit on OS X, but it’s slower than urxvt on Linux and I don’t like its HiDPI handling). Also related and interesting is this Dan Luu writeup on Terminal latency.
And that wraps up today’s episode of Yak Shavers. This might become an ongoing series as I tweak some of the remaining issues on my Linux systems (next might be migrating from 1Password due to the Firefox plugin being broken, or better notification supression when videos are playing). Past issues/fixes have been largely chronicled in my Arch Linux Install doc, although a number of new things are in a private wiki. One of my goals this year is to figure out the best way to publish most of that stuff publicly.
By far the most insecure piece of software that I still run on my main web server these days (where you’re reading this!) is WordPress. It seems like there’s never more than a few months (also) that go by without some new XML-RPC exploit or some-such pops up. The easiest way to stay reasonably secure is with regular updates. About 4 years ago I automated that with a simple daily WP-CLI (best tool) update script that basically looks like:
I also run a few security plugins, like Activity Log, WP fail2ban, and Sucuri Security and I haven’t seemed to have had too many problems over the past few years on my main blog, however my terribly neglected travel blog apparently wasn’t getting regular updates this past year and needed a bit of delousing (some spam urls etc, that just needed to be reverted) – the sad thing is that it had an update script, but wasn’t being run in cron (wah wah).
I originally had somewhat more ambitious plans for my 2017 wrap up, but well, the end of the year is just about here so instead I’ll just type for a couple hours, hit publish, and call it a day.
Part of the motivation is that it’s felt like a good time again to write up some of what I’ve been thinking about in technology trends. In 2006, while I was hip-deep in Web 2.0 work (and my blog output had already fallen into the abyss where it remains today) and I wrote up a 5 year tech projection. I ended up revisiting it 5 years later and you know what, didn’t too badly. What’s interesting reviewing it now is the a few of the things that I had missed were actually on the cusp then and happened shortly after. I didn’t do a direct followup, but did do a 2013 Review in Tech writeup – the most interesting things that happened that year weren’t in consumer/SV tech scene (which was deep in their Uber for X/app obsession at the time).
In 2014 I started collecting some Emerging Tech notes that I never published. That might be worth checking out (there are some late 2017 notes as well) – these seemed to have caught the tech zeitgeist a couple years in advance but it’s a bit fuzzy on how these will play out. This year, I also started collected some notes on a future-trend focused Tumblr (it’s not private per-se, just not very publicized/widely read, although the same can be said for this blog at this point – just pissing into the wind). For 2018, I’m hoping to both publish more and to better rationalize where/how I’m publishing what I’m tracking.
Now enough of that, and into the weeds. Per usual, I spent a lot of time reading things this year (example) – too much on Twitter and Reddit, but on the whole, more worthwhile things than not – I spent a fair amount of time digging through writings of the socio-techno-political variety, lots on crypto-economics and other financial topics, and rounded off by the usual geek topics. Also, a lot more YouTube than usual. This marked year 4 of semi-nomadicism although I may spend some more time settled to try to get through a backlog of housekeeping. Being out and about in different parts of the world helps give some perspective (places visited for the first time included Colombia, Cuba, Iceland, Greece, Kazakhstan, and Brazil).
Like many others, I spent much of the end of last year and the beginning of this year reading and thinking about the state (and fate) of liberal democracy in the modern world. I collected some of that into a doc Sensemaking in the Age of Social Media. While most of the participants haven’t realized it yet (or are disingenously denying it), we are now living in the age of weaponized information – memetic warfare. This is as cyberpunk and dystopian as it sounds, and it’s worth giving a shout out to sci-fi authors. The easiest way to understand where we are is to re-read Gibson, Sterling, Stephenson, Egan, Stross, Doctorow et al with the lens of what we are experiencing. It’s also worth thinking about how unprepared humans and human societies currently are against the future-shock mechanization of the modern infosphere (hyper-personalization and filter bubbles, bot/troll manipulation and other social signal hacks, infoglut and overload, clickbait and yes, fake news). These are second order effects that web pioneers and SV techies were unprepared for and misincentivized to address (who knew that driving engagement for advertising revenue would bring down free society, wah wah). This of course made it’s way into the news zeitgeist this year (that the modern media landscape is a key part of this dysfunction is an irony that is sadly lost to most, I believe). A smattering of headlines: Former Facebook executive: social media is ripping society apart, Facebook must wake up to its disastrous potential – it has the power to subvert American democracy, What Facebook Did to American Democracy, Facebook Wins, Democracy Loses, Can democracy survive Facebook? – now this is all a bit unfair to Facebook, after all Twitter is perhaps even more of a trash fire (and @realDonaldTrump will probably start WW3 on it next year). Anyway, before I go full rant – there aren’t easy answers, but it’s clear that we must fix this. These are design failures – some driven purposefully by misaligned economic incentives and externalized risk, and some by the short-sightedness and failings of designers, engineers, and product managers. IMO, if we can not fix this, humanity will probably not survive.
Over the course of the year I tried to crystallize a line of thought – that there were no problems humanity faced that could not be solved, if we could solve the problem of how to cooperate in rational self interest. Not such a deep insight, and not pithy enough yet (still a work in progress, obviously) but good enough as a direction to point one’s mental energy and efforts towards. (For those in doubt, and as a benchmark for this, nominal global GDP is about 80T USD – look at any looming existential crisis that we face and ask how much actual effort/cost it would take to address, mitigate, or fix.)
Also tying into perhaps the next topic, on cryptocurrencies. Or perhaps, more accurately a discussion on distributed trust network, or resilient distributed consensus in the presence of byzantine adversaries, or about censorship-resistant transactions, or incentivization structures for said networks.
Yes, we are currently in a bit of a mania phase of a bubble at the moment. One that hasn’t, but will inevitably pop (although I wouldn’t pack it in until the institutional money gets a dip – this might not even be the big bubble yet in the same way that 2014 wasn’t). At the end of it though we’ll be where we were at the end of the Internet bubble – with a whole bunch of new toys to play with that with the power to reshape society. Hopefully, having gone through it once already, we can try again a bit wiser.
A few interesting recent reads that might spark some ideas:
OK, well, enough of that. Perhaps a bit less on the tech insights than a more planned essay would have been. My resolution for the coming year will be to figure out a better way of collecting and publishing my research on an ongoing basis. Maybe not quite gwern style but I think that a lot of what I come across and read about might be useful to others, and the act of publishing would probably encourage better organization/clear thinking. Another resolution: trying to waste less time on the Internet.
One last cryptocurrency and society link, this essay on ledgers and “cryptoeconomics” (defined within as “the institutional consequences of cryptographically secure and trustless ledgers is some good food for thought.
We’re not done though. I tried my luck on clicking around a more 80s JPop tracks (good, but nothing mindblowing) until I got to this 80’s Japanese mixtape. The first track by Tatsuro Yamashita, Hot Shot, is fantastic.
This recent St. Vincent performance popped up in my feed today:
Which was good, but led to a much more interesting video, a series called “Guitar Moves” (interestingly, this one was apparently pulled from the original channel for some reason)
The finger-style rock guitaring got me thinking about what M Ward is up to these days (Gibson sponsorship apparently). Here he is jamming backstage in 2007:
Here’s a 2016 live KEXP set:
The KEXP YouTube channel is great, btw. One of my favorite vids from last year (I don’t think I ever posted it here) was this rendition of Okkervil River’s Unless It’s Kicks (completely different from the album version, totally awesome – the strat and the bass combo, just fantastic):
Back on the M Ward tip, ended up reading an old Gibson interview watching a couple She & Him vids. From their second album (listening to the V0 on good cans is actually much more interesting)
which led to a much more recent 2014 video:
The top comment asks to see the green onesie, and sure enough, here’s the making of:
Fun stuff. Oh, also today:
To be clear: They didn't take all the stats down. They only took down the ones they didn't like.
One of the things that never fails to surprise me is the sheer amount of amazing/interesting stuff that pops up every day. Over the past few months, I’ve quietly been trying to capture a few of the highlights and have been planning on figuring out a better system, here for example is a more complete list of stuff just from the past day or two of my reading. Most of this I have just sent to Pocket or my ever growing Watch List (there simply aren’t enough hours in the day):
The Shouting Class – a fantastic and very insightful essay on how social media has changed the nature of social discourse
It’s worth noting that this is a sampling from about one day’s worth of bookmarks one three aggregators (Twitter, Hacker News, and Reddit) that I only check a few times over the course of the day (this was on a travel day no less). Also that simply going back and gathering and sifting all these out took about an hour this morning.
Putting a little bit of thought on how to better manage all this.
I was traveling most of March, so I wasn’t in a launch-day rush, but after reading some reviews, I saved a couple hundred bucks and went with a $320 Ryzen 7 1700. As a bonus, the 1700 comes with a nice looking (and pretty functional) CPU cooler and my copy easily overclocks to 3.7GHz (3.8-3.9 pushing voltages, but I’d probably upgrade the cooler in that case – you can purchase pre-binned versions here).
I bought an MSI X370 Gaming Pro Carbon primarily because it was a nice monochrome look and had dual M.2 support (only the first slot runs at PCIe 3.0 x4 sadly due to the Ryzen 7/x370’s PCIe lane availability), but I wouldn’t recommend it. While it’s had some BIOS updates, it still doesn’t have the latest 4/10 AGESA update, and in general has had sluggish support and a few issues (my personal gripes: pokey POSTing, no last-good/soft-CMOS reset). Personally, if I was buying a top-of-the-line board, I’d probably go with the Asus ROG CH6 – while it doesn’t have a second M.2 slot, you could put a PCIe adapter board on the last slot for that. As a bonus, there are a bajillion USB ports.
Instead of buying new GPUs, I just brought along a couple RX470 mining cards (sadly, these two weren’t running the past two months – that would have been $400-600 of missed earnings w/ the ETH run-up). I have them beavering away in the background right now while the system idles. (I am running the latest 17.4.2 drivers but with a BIOS signature check bypass).
One note during installation is that I had hard-lockup problems when installing from a 2015 Windows 10 stick – you’ll want to make a new one, w/ a 12/2016 ISO I didn’t have any problems.
While my VR development has been a bit sidetracked recently (one guess why), with the release of Nvidia’s Pascal 10-series mobile GPUs, I’ve been looking forward to abandoning my previous portable VR workstations and switching to a more traditional, relatively compact laptop.
I was originally most interested in the Aorus X3 Plus V6, but its release was so delayed, that I ended up preordering the Dell Alienware 13R3 when it was announced in November. Due to some discount hijinks (and the fact that it hadn’t shipped when it was scheduled to), I ended up reordering during the Black Friday sales. Delivery was originally scheduled for Dec 5, but got pushed back until the 22nd, by which time I was already out of the country, so I only this week finally had a chance to break it out and put it through its paces.
So, first, some positive things:
OLED screen – the main reason I decided I wanted the Alienware 13, despite the long wait and a few other concerns, was because of the screen. While only 60Hz, the OLED pixels really are glorious – sharp, contrasty, with 1ms switching and a ridiculous color gamut (104% AdobeRGB). It’s a capacitive multitouch screen (I don’t like to touch my screens but the one time I accidentally did, it seemed to work), and it’s mounted on a very solid hinge that doesn’t not wobble *at all* when typing. There is an achilles heel, but I’ll save that for the ‘cons’ section.
Good performance – If you order the 13R3 now, you’ll get the latest Kaby Lake (7-series) processor – mine was in the one-month window where the Skylake (6-series) shipped, however the performance difference is minimal (the Kaby Lake might have an ever so slightly better boost clock). I got mine with the highest specced i7-6700HQ that despite worries due to thermal problems in many early subreddit threads, ended up running fine. CPU stress tests clocked it at about 75-80C running at a boost clock of 3.1-3.2GHz, with even lower temperatures undervolting w/ Intel XTU. Sadly, when running benchmarks like Valley or gaming, the system still ended up being about 20% slower than my compact (stock) i7-4790K and GTX970 combo, but I doubt that any other GTX1060 based portable system would do much better (the GPU clock of the GTX1060 didn’t boost to 1900MHz, but stayed a reasonable 1600-1700MHz at around 80-85C while gaming).
The keyboard and trackpad were top notch, both in feel, and surprisingly, with the lighting on the trackpad (this is configurable, but by default the trackpad glows when in use and it’s actually pretty neat). The top plate is a soft touch plastic that is nice, although even over a couple days of light use, has started to acquire a few spots of sheen (ick, I know).
The Webcam has IR support for Tobii eye tracking (never used) and Windows Hello logins (which actually works great and is delightful)
Build quality is super solid – it’s built like a tank and it feels like you could definitely use it as a bludgeoning tool and then continue on your merry way. It’s also worth noting that swapping RAM (2 slots) or m.2 SSDs (2 slots) is a breeze – literally 5 phillips screws on the bottom, which is a big plus. The service manual is online, and overall, near complete disassembly looks like a breeze.
Due to the delays, I ended up calling Dell customer service a few times, and while not always completely helpful, I didn’t have to spend too long on hold and most of the time it felt like they were moving the ball along, so kudos for that.
OK, now with the cons, which includes some pretty serious stuff, sadly.
The screen – As I mentioned, one of the main reasons I picked the Alienware 13 over anything else was the OLED screen. And it really is glorious – as long as you are in complete darkness that is (that Achilles heel I mentioned). Even in indirect or low ambient light, the screen is basically a mirror, and if you like running dark text terminals like me (which would also be better for the OLED’s battery life), you will spend a lot of time staring at your own reflection. I really can’t fathom why someone would have such an otherwise awesome display and then put it behind such a glossy piece of glass.
Size and weight – While the build quality is admirable, and in theory I knew it was heavier than some of the alternatives, it’s not until you get it in your hands do you realize how bulky it really is. The computer itself is 2.5kg (5.5lb), and the power brick is another 0.8kg (1.7lb) on top of that. In total, you’re looking at almost 3.3kg (7.2lb) for the package. The sizing isn’t much better. It’s relatively thick at about 24-27mm (the other dimensions aren’t super small either), but worst of all, the center of the laptop is actually pointy, not flat. This makes propping the laptop up or using many laptop stands a non-starter. I don’t really know what Alienware was thinking with that design element.
Battery life – shorter battery life is something that I expected but in practice, turned out to be unacceptably low (much lower than reviews and claims I had seen) 84t92ao. In my unscientific rundown test of random web browsing and YouTube video watching, I got 3h 10m of use from a full charge before it shut down. This was in a darkened room and I don’t think I heard the fans turn on once mind you, so I don’t think it was stressing the system (also, w/ the OLED screen, you can’t disable Optimus, so I assume it wasn’t working out the dGPU even).
I paid a few bucks extra for the Killer 1535 (vs 1435) network card, which is supposed to have solved some of the older 1435’s connection problems. I also uninstalled the Killer Suite and reinstalled just the drivers, as that’s supposed to help as well. Alas, for whatever reason, the 1535 would drop connection (well, remain connected but time out on packets) about once a day. I have half a dozen devices running on my AC wifi without issues, so I’ll lay the blame on the card – it’s a relatively minor issue since it’d only be about $30 and 5 minutes to swap it out w/ an Intel wifi card, but I figure I’d mention it, while I’m piling on.
As I mentioned, there’s some minor throttling under gaming loads (1600-1700MHz on the GPU vs the 1900MHz max boost), although angling the laptop for better ventilation didn’t seem to improve things much. I also noticed some minor occassional graphics memory corruption in certain overlays in the game. Note: performance improved by about 10% after updating to the latest Nvidia WHQL drivers. There’s probably more I could have done to tweak out performance, but the screen, life, and bulk really killed my enthusiam
As you might expect, after a few days realizing some of the shortcomings, I’ve ended up deciding to return the system. I think for those that don’t fly/travel as much, or that don’t mind extremely glossy screens (there must be a lot of people like that, because I feel like Dell isn’t the only offender here), this might be a good fit. There really are a lot to admire here, and the reviews that I read/watched were mostly positive, so I don’t want to give the impression that this laptop is a total stinker.
For those looking at lightweight/portable VR capable workstations, your options are still sort of limited. I’ve ordered a Gigabyte Aero 14 that will hopefully address the worst issues I had with the Alienware 13 – it has a matte anti-glare IPS display (sadly w/ average color gamut), is 1.9kg (the 2.4kg weight with the power adapter is the same as the weight of the Alienware laptop by itself) and is almost 50% thinner. It also has a beefier 94Wh battery (Gigabyte has made claims for 10 hours of use, but honestly, I’d be happy if it could hit 5h of web browsing) and an Intel 8260 wifi card. Gentech is also offering a free liquid metal CPU+GPU repaste so I have some hopes that performance might actually be a bit better as well.
Here’s a couple video reviews of the Alienware 13:
(Just look at that glare in the Linus video – he doesn’t mention it at all)
