But to use vulgar words an age attestation must be passed first! /s

Inkscape is an indispensable tool for me. I use it for quick drawing and drafting, for presentation slides, illustrations, small-scale print works, and even just pictures for fun. It allows to combine freehand drawing and moving things around with very precise, CAD-like handling of shapes, sizes, coordinates, etc.

There are few tools that are very ingrained in my daily operations, stay for years, and would be hard to replace, like Emacs or Firefox; Inkscape is among them.

Résumé/CV: https://dmitry.cheryasov.info/resume/with-intro/

Email: in the resume

I'm an experienced software engineer, looking for a hands-on senior software engineer / tech lead position, backend-leaning, with significant frontend skills. I worked at companies of all kinds, from seed-stage startups to literal FAANG.

I always end up working in close interaction with product people, stakeholders, and (if lucky enough) prospective users. I'm used to working cross-functionally and cross-team, improving communication, coordinating work of several teams to build and operate the thing which the business needs. I prefer building the right thing without haste, but know how to prioritize shipping the most impactful changes sooner.

I value autonomy and high impact. I built things from a nebulous idea to a final implementation and production launch. I evolved large existing systems, including frontend, backend, and databases. I view AI coding tools positively, as a replacement of some human labor, but not of human judgment.

I'm glad to communicate with people, to mentor fellow engineers when appropriate, to coordinate work, but I'm not trying to become a full-time people manager. My north star is people like John Carmack or Rob Pike.


Could be more interesting for hard-to-reach underwater sensors. Water attenuates RF quite severely, but is good at conducting ultrasound. The response would have to be in ultrasound, too, of course.

The u.2 form factor is slightly larger than a 2.5" drive. I can imagine the entire space in it taken by Flash chips. I can't imagine what cooling scheme do they employ for the chips in the middle.

The U.2 form factor is a 2.5" drive, not larger than it.

"U.2" does not change anything in the mechanical characteristics of a 2.5" drive, it just replaces the SATA or SAS electrical interface with a NVMe electrical interface.

You can mount a U.2 drive in any location intended for 2.5" drives, as long as its height can fit there.

However, 2.5" drives come in various heights. Many laptops and mini-PCs that accept 2.5" drives accept only some of the smaller heights and they do not accept the greater heights, like 15 mm, which are typical for enterprise SSDs and HDDs, regardless whether they have a NVMe, i.e. U.2, or a SAS interface or a SATA interface.

This new high-capacity U.2 SSD has the standard 15 mm height of the 2.5" form factor.


Apparently TDP is 30 watts¹, according to the product brief. I would imagine it's a single PCB with flash chips on both sides then thermally bonded to the aluminum chassis. That should keep all chips at approximately the same temperature. On its own it could be easily air cooled, but with 24 in a 2U chassis you'll be having some decently hefty forced air over the drives.

1. For comparison, an HDD usually comes in around ~10 watts


It's not just a single PCB, but a sandwich of several.

The 4th Earl of Sandwich disagrees.

Given the cost of 24 of them, you can probably buy solid silver heatsinks watercooled with tears of sysadmins.

I was going to say blood of virgins, but tears are probably better heat conductors.

I tempted to say that blood is better one. Among other things blood has iron, while tears just salt. Last, but not least it's for thermoregulation of the body.

The tears of sysadmins are fairly cheap though.

It may be the only resource that truly scales with demand.

Hey! You leave me out of your twisted fantasy!

I just want....I just want hard drive prices to come back down. *sniffle*


The transfer rates limit how much each chip can be active at any given time, so a heat-aware writing allocator can pick the least active blocks for the next writes and distribute the heat accordingly. Even if it’s not heat-aware, the tendency will be that the writes will be distributed over as many chips as there are, and so will be the heat generated.

Now, I would LOVE to see this much SLC flash on a direct to bus attachment setting.


Over the past few years the main improvement in SSD capacity has been due to them stacking an ever-increasing number of NAND layers in a single chip, with state-of-the-art SSDs already having over 300 layers.

No need to worry about cooling when each layer in the sandwich is only a fraction of a micrometer thick!


the u.2 form factor indeed evolved from chassis designs that were originally 2.5" drives. It's now kind of becoming obsolete with new designs using things like E1S, E1L (exactly the correct height to be slotted into a 1U server, it's like a slightly wider M.2, but meant to be insertable and removable), and E3S and E3L.

Note that the 245TB is an E3L, the half size version of it come in smaller size.

You can put color labels on top of cards, so that they look distinct even in a typical physical wallet that only shows the top part of each card.

Or, say, Google Wallet shows you can the last 4 digits, and allows to name a card, so choosing between identical-looking cards of the same bank is easy (I do it regularly).

But Apple are not fans of letting the user customize things.


Has this been even clicked through by a human? The link to TinyStack goes to a domain parking page, and the link to Zimki leads to a slideshare presentation.

There's not even a blurb that explains what a particular SaaS / PaaS offering is good at, just favicons and links. This is an opposite to a real, curated "awesome-<something>" list.


It is backed by github repo, where in creators create a PR. This website is backed by that. This is purely community driven.

I did a quick sanity check before posting. I will do a better housekeeping. I'll remove bad links.

Please note zimki is an honarary mention as it was first paas ever created by canon. Redirect to slideshare is purposely done.


Thank you for the quick and constructive reaction! It makes me want to offer an improvement PR now :)

Please feel free. I do not make any money with this nor there is any hidden intentions here. I am doing this because I am genuinely passionate about PaaS, containers and devops.

I started this when my company as into PaaS. Now we are not, but I still curate and maintain it.


Some links lead to gambling landing pages e.g. backery

Link has been updated.

More seriously: what good an age restriction is if it can be circumvented by a VPN?

A litmus test in the law for "good" (freedom-respecting) laws and "bad" (moral judgement/forcing homogenous morals) laws.

Utah has chosen, unfortunately, to abrogate the rights of parents to raise their children and to allow people to engage privately online.


There's still plenty of difference between e.g. Texas and California.

There ought to be some significant level of cohesion between constituent states in a federation (like the US or India) or even a confederation (like the EU or Switzerland), else the common market and the common law system won't be able to function. It should not be overdone though.


Blue states are mostly states with large coastal cities, and thus larger incomes.

You seem to forget that those states tend to have rural (red) populations that get affected by the laws the larger population in the cities pass at the state level.

This is true. I just mean that moving becomes less hard if you earn more due to the general higher level of wages in your area near a big and prosperous city.

Sure, but that doesn't work if you're in the scenario we are talking about - red person in a rural part of a blue state. They will still have restricted income.

I am trying to think of examples of blue state majorities oppressing rural populations.

Allowing gays to marry if they want, does that count as oppressing rural Christians?


It usually takes the form of rules and regulations that are well-intentioned in a big city but make zero sense in a self-reliant community of 100 people that all know each other.

ADA regulations are good example, and also a common punching bag of the rural right in a blue state. Making sure everything is handicapped-accessible is important in a restaurant in San Francisco with a visitor pool of about 7 millions. It makes zero sense when it is the only restaurant in a town of 100, none of whom are disabled*. Nobody's available to build the necessary accommodations, and nobody's going to use them.

Gun regulations too. When you come in contact with thousands of people routinely and some of them might wish to kill you, limiting the ability to buy guns is important. When hunting and scaring off wild animals is a large part of your lifestyle, you can go a week without seeing another human, and the local police department takes 2 hours to get to you? Now you're just taking away essential tools for survival.


If you actually want to look at this seriously, check out things like gun control, VA's redistricting, etc.
