2019 is special in my heart. 2019 was different than many other years to me in several ways. It was a great year! This is what 2019 was to me.
curl and wolfSSL
I quit Mozilla last year and in the beginning of the year I could announce that I joined wolfSSL. For the first time in my life I could actually work with curl on my day job. As the project turned 21 I had spent somewhere in the neighborhood of 15,000 unpaid spare time hours on it and now I could finally do it “for real”. It’s huge.
Just in November 2018 the name HTTP/3 was set and this year has been all about getting it ready. I was proud to land and promote HTTP/3 in curl just before the first browser (Chrome) announced their support. The standard is still in progress and we hope to see it ship not too long into next year.
Focusing on curl full time allows a different kind of focus. I’ve landed more commits in curl during 2019 than any other year going back all the way to 2005. We also reached 25,000 commits and 3,000 forks on github.
We’ve added HTTP/3, alt-svc, parallel transfers in the curl tool, tiny-curl, fixed hundreds of bugs and much, much more. Ten days before the end of the year, I’ve authored 57% (over 700) of all the commits done in curl during 2019.
We also (re)started our own curl Bug Bounty in 2019 together with Hackerone and paid over 1000 USD in rewards through-out the year. It was so successful we’re determined to raise the amounts significantly going into 2020.
I’ve done 28 talks in six countries. A crazy amount in front of a lot of people.
When Github had their Github Universe event in November and talked about their new sponsors program on stage (which I am part of, you can sponsor me) this huge quote of mine was shown on the big screen.
Maybe not media, but in no less than two Mr Robot episodes we could see curl commands in a TV show!
I view myself as primarily a software developer. Perhaps secondary as someone who’s somewhat knowledgeable in networking and is participating in protocol development and discussions. I do not regularly proclaim myself to be a “speaker” or someone who’s even very good at talking in front of people.
Time to wake up and face reality? I’m slowly starting to realize that I’m actually doing more presentations than ever before in my life and I’m enjoying it.
Since October 2015 I’ve done 53 talks and presentations in front of audiences – in ten countries. That’s one presentation done every 25 days on average. (The start date of this count is a little random but it just happens that I started to keep a proper log then.) I’ve talked to huge audiences and to small. I done presentations that were appreciated and I’ve done some that were less successful.
My increased frequency in speaking engagements coincides with me starting to work full-time from home back in 2014. Going to places to speak is one way to get out of the house and see the “real world” a little bit and see what the real people are doing. And a chance to hang out with humans for a change. Besides, I only ever talk on topics that are dear to me and that I know intimately well so I rarely feel pressure when delivering them. 2014 – 2015 was also the time frame when HTTP/2 was being finalized and the general curiosity on that new protocol version helped me find opportunities back then.
Public speaking is like most other things: surprisingly enough, practice actually makes you better at it! I still have a lot to learn and improve, but speaking many times has for example made me better at figuring out roughly how long time I need to deliver a particular talk. It has taught me to “find myself” better when presenting and be more relaxed and the real me – no need to put up a facade of some kind or pretend. People like seeing that there’s a real person there.
I’m not even getting that terribly nervous before my talks anymore. I used to really get a raised pulse for the first 45 talks or so, but by doing it over and over and over I think the practice has made me more secure and more relaxed in my attitude to the audience and the topics. I think it has made me a slightly better presenter and it certainly makes me enjoy it more.
I’m not “a good presenter”. I can deliver a talk and I can do it with dignity and I think the audience is satisfied with me in most cases, but by watching actual good presenters talk I realize that I still have a long journey ahead of me. Of course, parts of the explanation is that, to connect with the beginning of this post, I’m a developer. I don’t talk for a living and I actually very rarely practice my presentations very much because I don’t feel I can spend that time.
Some of the things that are still difficult include:
The money issue. I actually am a developer and that’s what I do for a living. Taking time off the development to prepare a presentation, travel to a distant place, sacrifice my spare time for one or more days and communicating something interesting to an audience that demands and expects it to be both good and reasonably entertaining takes time away from that development. Getting travel and accommodation compensated is awesome but unfortunately not enough. I need to insist on getting paid for this. I frequently turn down speaking opportunities when they can’t pay me for my time.
Saying no. Oh my god do I have a hard time to do this. This year, I’ve been invited to so many different conferences and the invitations keep flying in. For every single received invitation, I get this warm and comfy feeling and I feel honored and humbled by the fact that someone actually wants me to come to their conference or gathering to talk. There’s the calendar problem: I can’t be in two places at once. Then I also can’t plan events too close to each other in time to avoid them holding up “real work” too much or to become too much of a nuisance to my family. Sometimes there’s also the financial dilemma: if I can’t get compensation, it gets tricky for me to do it, no matter how good the conference seems to be and the noble cause they’re working for.
Feedback. To determine what parts of the presentation that should be improved for the next time I speak of the same or similar topic, which parts should be removed and if something should be expanded, figuring what works and what doesn’t work is vital. For most talks I’ve done, there’s been no formal way to provide or receive this feedback, and for the small percentage that had a formal feedback form or a scoring system or similar, taking care of a bunch of distributed grades (for example “your talk was graded 4.2 on a scale between 1 and 5”) and random comments – either positive or negative – is really hard… I get the best feedback from close friends who dare to tell me the truth as it is.
Conforming to silly formats. Slightly different, but some places want me to send me my slides in, either a long time before the event (I’ve had people ask me to provide way over a week(!) before), or they dictate that the slides should be sent to them using Microsoft Powerpoint, PDF or some other silly format. I want to use my own preferred tools when designing presentations as I need to be able to reuse the material for more and future presentations. Sure, I can convert to other formats but that usually ruins formatting and design. Then a lot the time and sweat I put into making a fine and good-looking presentation is more or less discarded! Fortunately, most places let me plug in my laptop and everything is fine!
As a little service to potential audience members and conference organizers, I’m listing all my upcoming speaking engagements on a dedicated page on my web site:
I try to keep that page updated to reflect current reality. It also shows that some organizers are forward-planning waaaay in advance…
Invite someone like me to talk?
Here’s some advice on how to invite a speaker (like me) with style:
Ask well in advance (more than 2-3 months preferably, probably not more than 9). When I agree to a talk, others who ask for talks in close proximity to that date will get declined. I get a surprisingly large amount of invitations for events just a month into the future or so, and it rarely works for me to get those into my calendar in that time frame.
Do not assume for-free delivery. I think it is good tone of you to address the price/charge situation, if not in the first contact email at least in the following discussion. If you cannot pay, that’s also useful information to provide early.
If the time or duration of the talk you’d like is “unusual” (ie not 30-60 minutes) do spell that out early on.
Surprisingly often I get invited to talk without a specified topic or title. The inviter then expects me to present that. Since you contact me you clearly had some kind of vision of what a talk by me would entail, it would make my life easier if that vision was conveyed as it could certainly help me produce a talk subject that will work!
What I bring
To every presentation I do, I bring my laptop. It has HDMI and USB-C ports. I also carry a HDMI-to-VGA adapter for the few installations that still use the old “projector port”. Places that need something else than those ports tend to have their own converters already since they’re then used with equipment not being fitted for their requirements.
I always bring my own clicker (the “remote” with which I can advance to next slide). I never use the laser-pointer feature, but I like being able to move around on the stage and not have to stand close to the keyboard when I present.
I never create my presentations with video or sound in them, and I don’t do presentations that need Internet access. All this to simplify and to reduce the risk of problems.
I work hard on limiting the amount of text on each slide, but I also acknowledge that if a slide set should have value after-the-fact there needs to be a certain amount. I’m a fan of revealing the text or graphics step-by-step on the slides to avoid having half the audience reading ahead on the slide and not listening.
I’ve settled on 16:9 ratio for all presentations. Luckily, the remaining 4:3 projectors are now scarce.
I always make and bring a backup of my presentations in PDF format so that basically “any” computer could display that in case of emergency. Like if my laptop dies. As mentioned above, PDF is not an ideal format, but as a backup it works.
One year ago today. On the sunny Tuesday of April 17th 2018 I visited the US embassy in Stockholm Sweden and applied for a visa. I’m still waiting for them to respond.
My days-since-my-visa-application counter page is still counting. Technically speaking, I had already applied but that was the day of the actual physical in-person interview that served as the last formal step in the application process. Most people are then getting their visa application confirmed within weeks.
Initially I emailed them a few times after that interview since the process took so long (little did I know back then), but now I haven’t done it for many months. Their last response assured me that they are “working on it”.
During this year I missed out on a Mozilla all-hands, I’ve been invited to the US several times to talk at conferences that I had to decline and a friend is getting married there this summer and I can’t go. And more.
Going forward I will miss more interesting meetings and speaking opportunities and I have many friends whom I cannot visit. This is a mild blocker to things I would want to do and it is an obstacle to my profession and career.
I guess I might get my rejection notice before my counter reaches two full years, based on stories I’ve heard from other people in similar situations such as mine. I don’t know yet what I’ll do when it eventually happens. I don’t think there are any rules that prevent me from reapplying, other than the fact that I need to pay more money and I can’t think of any particular reason why they would change their minds just by me trying again. I will probably give it a rest a while first.
I’m lucky and fortunate that people and organizations have adopted to my situation – a situation I of course I share with many others so it’s not uniquely mine – so lots of meetings and events have been held outside of the US at least partially to accommodate me. I’m most grateful for this and I understand that at times it won’t work and I then can’t attend. These days most things are at least partly accessible via video streams etc, repairing the harm a little. (And yes, this is a first-world problem and I’m fortunate that I can still travel to most other parts of the world without much trouble.)
Finally: no, I still have no clue as to why they act like this and I don’t have any hope of ever finding out.
If you want commercial support, ports of curl to other operating systems or just instant help to fix your curl related problems, we’re here to help. Get in touch now! This is the premiere. This has not been offered by me or anyone else before.
I’m not sure I need to say it, but I personally have authored almost 60% of all commits in the curl source code during my more than twenty years in the project. I started the project, I’ve designed its architecture etc. There is simply no one around with my curl experience and knowledge of curl internals. You can’t buy better curl expertise.
curl has become one of the world’s most widely used software components and is the transfer engine doing a large chunk of all non-browser Internet transfers in the world today. curl has reached this level of success entirely without anyone offering commercial services around it. Still, not every company and product made out there has a team of curl experts and in this demanding time and age we know there are times when you rather hire the right team to help you out.
We are the curl experts that can help you and your team. Contact us for all and any support questions at email@example.com.
What about the curl project?
I’m heading into this new chapter of my life and the curl project with the full knowledge that this blurs the lines between my job and my spare time even more than before. But fear not!
The curl project is free and open and will remain independent of any commercial enterprise helping out customers. I realize me offering companies and organizations to deal with curl problems and solving curl issues for compensation creates new challenges and questions where boundaries go, if for nothing else for me personally. I still think this is worth pursuing and I’m sure we can figure out and handle whatever minor issues this can lead to.
My friends, the community, the users and harsh critiques on twitter will all help me stay true and honest. I know this. This should end up a plus for the curl project in general as well as for me personally. More focus, more work and more money involved in curl related activities should improve the project.
It is with great joy and excitement I take on this new step.
Let me start by saying thank you to all and everyone who sent me job offers or otherwise reached out with suggestions and interesting career moves. I received more than twenty different offers and almost every one of those were truly good options that I could have said yes to and still pulled home a good job. What a luxury challenge to have to select something from that! Publicly announcing me leaving Mozilla turned out a great ego-boost.
I took some time off to really reflect and contemplate on what I wanted from my next career step. What would the right next move be?
I love working on open source. Internet protocols, and transfers and doing libraries written in C are things considered pure fun for me. Can I get all that and yet keep working from home, not sacrifice my wage and perhaps integrate working on curl better in my day to day job?
I talked to different companies. Very interesting companies too, where I have friends and people who like me and who really wanted to get me working for them, but in the end there was one offer with a setup that stood out. One offer for which basically all check marks in my wish-list were checked.
On February 5, 2019 I’m starting my new job at wolfSSL. My short and sweet period as unemployed is over and now it’s full steam ahead again! (Some members of my family have expressed that they haven’t really noticed any difference between me having a job and me not having a job as I spend all work days the same way nevertheless: in front of my computer.)
Starting now, we offer commercial curl support and various services for and around curl that companies and organizations previously really haven’t been able to get. Time I do not spend on curl related activities for paying customers I will spend on other networking libraries in the wolfSSL “portfolio”. I’m sure I will be able to keep busy.
I’ve met Larry at wolfSSL physically many times over the years and every year at FOSDEM I’ve made certain to say hello to my wolfSSL friends in their booth they’ve had there for years. They’re truly old-time friends.
wolfSSL is mostly a US-based company – I’m the only Swede on the team and the only one based in Sweden. My new colleagues all of course know just as well as you that I’m prevented from traveling to the US. All coming physical meetings with my work mates will happen in other countries.
It’s been five great years, but now it is time for me to move on and try something else.
During these five years I’ve met and interacted with a large number of awesome people at Mozilla, lots of new friends! I got the chance to work from home and yet work with a global team on a widely used product, all done with open source. I have worked on internet protocols during work-hours (in addition to my regular spare-time working with them) and its been great! Heck, lots of the HTTP/2 development and the publication of that was made while I was employed by Mozilla and I fondly participated in that. I shall forever have this time ingrained in my memory as a very good period of my life.
I had already before I joined the Firefox development understood some of the challenges of making a browser in the modern era, but that understanding has now been properly enriched with lots of hands-on and code-digging in sometimes decades-old messy C++, a spaghetti armada of threads and the wild wild west of users on the Internet.
A very big thank you and a warm bye bye go to everyone of my friends at Mozilla. I won’t be far off and I’m sure I will have reasons to see many of you again.
My last day as officially employed by Mozilla is December 11 2018, but I plan to spend some of my remaining saved up vacation days before then so I’ll hand over most of my responsibilities way before.
The future is bright but unknown!
I don’t yet know what to do next.
I have some ideas and communications with friends and companies, but nothing is firmly decided yet. I will certainly entertain you with a totally separate post on this blog once I have that figured out! Don’t worry.
Will it affect curl or other open source I do?
I had worked on curl for a very long time already before joining Mozilla and I expect to keep doing curl and other open source things even going forward. I don’t think my choice of future employer should have to affect that negatively too much, except of course in periods.
With me leaving Mozilla, we’re also losing Mozilla as a primary sponsor of the curl project, since that was made up of them allowing me to spend some of my work days on curl and that’s now over.
Short-term at least, this move might increase my curl activities since I don’t have any new job yet and I need to fill my days with something…
What about toying with HTTP?
I was involved in the IETF HTTPbis working group for many years before I joined Mozilla (for over ten years now!) and I hope to be involved for many years still. I still have a lot of things I want to do with curl and to keep curl the champion of its class I need to stay on top of the game.
I will continue to follow and work with HTTP and other internet protocols very closely. After all curl remains the world’s most widely used HTTP client.
Can I enter the US now?
No. That’s unfortunately not related, and I’m not leaving Mozilla because of this problem and I unfortunately don’t expect my visa situation to change because of this change. My visa counter is now showing more than 214 days since I applied.
I got myself a new 27″ 4K screen to my work setup, a Dell P2715Q, and replaced one of my old trusty twenty-four inch friends with it.
I now work with the “Thinkpad 13″ on the left as my video conference machine (it does nothing else and it runs Windows!), the two mid screens are a 24″ and the new 27” and they are connected to my primary dev machine while the rightmost thing is my laptop for when I need to move.
Did everything run smoothly? Heck no.
When I first inserted the 4K screen without modifying anything else in the setup, it was immediately obvious that I really needed to upgrade my graphics card since it didn’t have muscles enough to drive the screen at 4K so the screen would then instead upscale a 1920×1200 image in a slightly blurry fashion. I couldn’t have that!
New graphics card
So when I was out and about later that day I more or less accidentally passed a Webhallen store, and I got myself a new card. I wanted to play it easy so I stayed with an AMD processor and went with ASUS Dual-Rx460-O2G. The key feature I wanted was to be able to drive one 4K screen and one at 1920×1200, and then I unfortunately had to give up on the ones with only passive cooling and I instead had to pick what sounds like a gaming card. (I hate shopping graphics cards.)As I was about to do surgery on the machine anyway. I checked and noticed that I could add more memory to the motherboard so I bought 16 more GB to a total of 32GB.
Blow some fuses
Later that night, when the house was quiet and dark I shut down my machine, inserted the new card, the new memory DIMMs and powered it back up again.
At least that was the plan. When I fired it back on, it said clock and my lamps around me all got dark and the machine didn’t light up at all. The fuse was blown! Man, wasn’t that totally unexpected?
I did some further research on what exactly caused the fuse to blow and blew a few more in the process, as I finally restored the former card and removed the memory DIMMs again and it still blew the fuse. Puzzled and slightly disappointed I went to bed when I had no more spare fuses.
I hate leaving the machine dead in parts on the floor with an uncertain future, but what could I do?
A new PSU
Tuesday morning I went to get myself a PSU replacement (Plexgear PS-600 Bronze), and once I had that installed no more fuses blew and I could start the machine again!
I put the new memory back in and I could get into the BIOS config with both screens working with the new card (and it detected 32GB ram just fine). But as soon as I tried to boot Linux, the boot process halted after just 3-4 seconds and seemingly just froze. Hm, I tested a few different kernels and safety mode etc but they all acted like that. Weird!
A little googling on the messages that appeared just before it froze gave me the idea that maybe I should see if there’s an update for my bios available. After all, I’ve never upgraded it and it was a while since I got my motherboard (more than 4 years).
I found a much updated bios image on ASUS support site, put it on a FAT-formatted USB-drive and I upgraded.
Now it booted. Of course the error messages I had googled for are still present, and I suppose they were there before too, I just hadn’t put any attention to them when everything was working dandy!
Displayport vs HDMI
I had the wrong idea that I should use the display port to get 4K working, but it just wouldn’t work. DP + DVI just showed up on one screen and I even went as far as trying to download some Ubuntu Linux driver package for Radeon RX460 that I found, but of course it failed miserably due to my Debian Unstable having a totally different kernel running and what not.
In a slightly desperate move (I had now wasted quite a few hours on this and my machine still wasn’t working), I put back the old graphics card – (with DVI + hdmi) only to note that it no longer works like it did (the DVI one didn’t find the correct resolution anymore). Presumably the BIOS upgrade or something shook the balance?
Back on the new card I booted with DVI + HDMI, leaving DP entirely, and now suddenly both screens worked!
HiDPI + LoDPI
Once I had logged in, I could configure the 4K screen to show at its full 3840×2160 resolution glory. I was back.
Now I only had to start fiddling with getting the two screens to somehow co-exist next to each other, which is a challenge in its own. The large difference in DPI makes it hard to have one config that works across both screens. Like I usually have terminals on both screens – which font size should I use? And I put browser windows on both screens…
So far I’ve settled with increasing the font DPI in KDE and I use two different terminal profiles depending on which screen I put the terminal on. Seems to work okayish. Some texts on the 4K screen are still terribly small, so I guess it is good that I still have good eye sight!
24 + 27
So is it comfortable to combine a 24″ with a 27″ ? Sure, the size difference really isn’t that notable. The 27 one is really just a few centimeters taller and the differences in width isn’t an inconvenience. The photo below shows how similar they look, size-wise:
I’ve been running a keylogger on my main Linux box for exactly one year now. The keylogger logs every key-press – its scan code together with a time stamp. This now allows me to do some analyses and statistics of what a year worth of using a keyboard means.
This keyboard being logged is attached to my primary work machine as well as it being my primary spare time code input device. Sometimes I travel and sometimes I take time-off (so called vacation) and then I usually carry my laptop with me instead which I don’t log and which uses a different keyboard layout anyway so merging a log from such a different machine would probably skew the results a bit too much.
What did I learn?
A full year of use meant 6.76 million keys were pressed. I’ve used the keyboard 8.4% on weekends. I used the keyboard at least once on 298 days during the year.
When I’m active, I average on 2186 keys pressed per hour (active meaning that at least one key was pressed during that hour), but the most fierce keyboard-bashing I’ve done during a whole hour was when I recorded 8842 key-presses on June 9th 2015 between 23:00 and 24:00! That day was actually also the most active single day during the year with 63757 keys used.
In total, I was active on the keyboard 35% of the time (looking at active hours). 35% of the time equals about 59 hours per week, on average. I logged 19% keyboard active minutes, minutes in which I hit at least one key. I’m pretty amazed by that number as it equals almost 32 hours a week with really active keyboard action.
Zooming in and looking at single minutes, the most active minute occurred 15:48 on November 10th 2014 when I managed to hit 405 keys. Average minutes when I am active I type 65 keys/minute.
Looking at usage distribution over week days: Tuesday is my most active day with 19.7% of all keys. Followed by Thursday (19.1%), Monday (18.7%), Wednesday (17.4%) and Friday (16.6%). I already mentioned weekends, and I use the keyboard 4.8% on Sundays and a mere 3.6% on Saturdays.
Separating the time-stamps over the hours of the day, the winning hour is quite surprising the 23-00 hour with 11.9% followed by the more expected 09-10 (10.0%), 10-11 and 14-15. Counting the most active minutes over the day shows an even more interesting table. All the top 10 most active minutes are between 23-00!
The most commonly pressed keys are: space (10%) and backspace (6.5%) followed by e, t, a, s, left control, i, cursor down, o, cursor up, n, r. 29 keys were pressed more than 1% of the times. 30 keys were pressed less than 0.01%. I used 99 different keys over the year (I believe my keyboard has 105 keys).
Never pressed keys? All 6 of the never touched keys are in the numpad: 2, 3, 5, 6, 9 and the comma/del key.
I’ll let the keylogger run and see what else I’ll learn over time…
It still feels like it was just a very short while ago and I keep having this sense of being a beginner at the company, in the source tree and all over.
One year of networking code work that really at least during periods has not progressed as quickly as I would’ve wished for, and I’ve had some really hair-tearing problems and challenges that have taken me sweat and tears to get through. But I am getting through and I’m enjoying every (oh well, let’s say almost every) moment.
During the year I’ve had the chance to meetup with my team mates twice (in Paris and in Portland) and I’ve managed to attend one IETF (in London) and two special HTTP2 design meetings (in London and NYC).
I’ve barely started. I’ll spend the next year as well improving Firefox networking, hopefully with a higher turnout this year. (I don’t mean to make this sound as if Firefox networking is just me, I’m just speaking for my particular part of the networking team and effort and I let the others speak for themselves!)
A while ago I wrote about my hunt for a new keyboard, and in my follow-up conversations with friends around that subject I quickly came to the conclusion I should get myself better analysis and data on how I actually use a keyboard and the individual keys on it. And if you know me, you know I like (useless) statistics.
So, I tried out the popular and widely used Linux key-logger software ‘logkeys‘ and immediately figured out that it doesn’t really support the precision and detail level I wanted so I forked the project and modified the code to work the way I want it: keyfreq was born. Code on github. (I forked it because I couldn’t find any way to send back my modifications to the upstream project, I don’t really feel a need for another project.)
Then I fired up the logging process and it has been running in the background for a while now, logging every key stroke with a time stamp.
Counting key frequency and how it gets distributed very quickly turns into basically seeing when I’m active in front of the computer and it also gave me thoughts around what a high key frequency actually means in terms of activity and productivity. Does a really high key frequency really mean that I was working intensely or isn’t that purpose more a sign of mail sending time? When I debug problems or research details, won’t those periods result in slower key activity?
In the end I guess that over time, the key frequency chart basically says that if I have pressed a lot of keys during a period, I was working on something then. Hours or days with a very low average key frequency are probably times when I don’t work as much.
The weekend key frequency is bound to be slightly wrong due to me sometimes doing weekend hacking on other computers where I don’t log the keys since my results are recorded from a single specific keyboard only.
So what did I learn? Here are some conclusions and results from 1276614 keystrokes done over a period of the most recent 52 calendar days.
I have a 105-key keyboard, but during this period I only pressed 90 unique keys. Out of the 90 keys I pressed, 3 were pressed more than 5% of the time – each. In fact, those 3 keys are more than 20% of all keystrokes. Those keys are: <Space>, <Backspace> and the letter ‘e’.
<Space> stands out from all the rest as it has been used more than 10%.
Only 29 keys were used more than 1% of the presses, giving this a really long tail with lots of keys hardly ever used.
Over this logged time, I have registered key strokes during 46% of all hours. Counting only the hours in which I actually used the keyboard, the average number of key strokes were 2185/hour, 36 keys/minute.
The average week day (excluding weekend days), I registered 32486 key presses. The most active sinngle minute during this logging period, I hit 405 keys. The most active single hour I managed to do 7937 key presses. During weekends my activity is much lower, and then I average at 5778 keys/day (7.2% of all activity were weekends).
When counting most active hours over the day, there are 14 hours that have more than 1% activity and there are 5 with less than 1%, leaving 5 hours with no keyboard activity at all (02:00- 06:59). Interestingly, the hour between 23-24 at night is the single most busy hour for me, with 12.5% of all keypresses during the period.
Longest contiguous time without keys: 26.4 hours
Longest key sequence without backspace: 946
There are 7 keys I only pressed once during this period; 4 of them are on the numerical keypad and the other three are F10, F3 and <Pause>.
I’ll try to keep the logging going and see if things change over time or if there later might end up things that can be seen in the data when looked over a longer period.
