WHO STOLE MY DISK SECTOR

what

this is a different disk.

did two disks on my desk go bad at the same time? or is this USB drive A USELESS FAILURE?

ok I'm trying a third disk and if this fails this drive is going right in the lake

it wrote successfully! now I can install some MS-DOS 6.22

dang it. after all that time installing it, it can't boot.
it doesn't even fail to boot, it just hangs at boot

some stupid problem with partitioning/mbr, probably

yup. boot disk, fdisk /mbr, and now it boots fine.

now I can get some REAL work done.

god I love this ANSI art floppy disk

wait, you can't do that. that's illegal

this is not how Doom is supposed to run, man.
isn't this shit a 486? yeah, it's a 66mhz 486.
the fuck?

so why is it benchmarking like a fucking tandy 1000? an 16mhz 8086!

OK I fixed some bios settings and it's now as fast as a 25 mhz.
huh.
This cyrix really sucks, eh?

better? crappy, but better.

ok the chip is a Cx486SLC2.
That's really a 386... but it should be running at 50mhz. it definitely isn't.

So I can adjust the CPU speed by changing jumper 8... which isn't there. They hardwired it.

And JP9, which is also hardwired

JP10 isn't hardwired, thankfully.

so that means I can do 16mhz or 25 mhz.

and it's currently on 16mhz.

well, let's try 25mhz!

Better!

still not great, but it feels a little better.

I wonder if I could overclock this stupid 386. I could desolder that hardwired jumper and replace it with a real jumper...

this board is never gonna be fast, though.
it's got a 486-labeled 386 soldered to the board, and zero cache.
very very limited entry-level board, this.

ok maybe overclocking the 386 is a bad idea.
(I haven't done it yet, this is just how hot it gets at 25mhz)

It may also be the VGA card I'm using. It's an ATI mach32, which is designed for accelerated windows 3.1 use, it might be slow at mode X stuff

or mode Y. I forget which one Doom uses. I think it's Y

love to see a youtube video that references a script that's linked in the comments and it's an obfuscated link to a one-click hoster.

THAT'S DEFINITELY STILL GONNA WORK IN FOUR YEARS

it does still work, but that's because it's only been 2 years.

also, wow, this is horrible.

the script is to generate random kanji/han characters and insert them into minecraft books.
but the video references there being two hotkeys to generate two distinct books, which seemed odd. so I thought I'd check.

it turns out by "random" they mean "pre-randomized and is hardcoded into the 45 kilobyte autohotkey scripot"

I mean, I get it. I don't want to write AutoHotKey scripts either. it's a horrible, horrible language.

BUT STILL

You want to know something about how bullshit insane our brains are?
OK, so there's a physical problem with our eyes: We move them in short fast bursts called "saccades", right? very quick, synchronized movements.
The only problem is: they go all blurry and useless during this

having your vision turn into a blurry mess every time you move your eyes is obviously not a good idea, so our brains hide it from us. Now, imagine you're an engineer and you have this problem.

You've got some obvious solutions you could do.
1. make the vision go black during movement. (Some VR games do this!)
2. just keep showing the last thing we saw prior to movement

both are good options with different downsides, but OH NO. this is assuming everything makes sense and is chronological and (regular) logical.
Your brain does neither of these options, really.

first, it basically puts your visual system on "pause". You're not seeing blackness or even nothing, you're just not seeing period.
then when you finish your saccade, it shows you what you now see at the new position. and then it pretends it can time travel.

So there's a class of puzzles called "river crossing puzzles" which involve having to cross a river on a boat/bridge containing some set of individuals/items with restrictions on which ones can be on the boat/left on each shore, right?

and the most common subclass of these problems is the one where you have 3 items/animals to cross with.
This is alternatively called the "fox, goose, and bag of beans" or "wolf, goat, and cabbage" puzzle.

the idea is that your boat can only carry one item at a time, but if you leave the wolf/fox unattended with the goat/goose, the wolf/fox will eat the goat/goose.
and similarly, the goose/goat will eat the beans/cabbage if left alone

so you have to set up a set of actions that never leaves either side of the river in one of the lose-states.

the solution to this variant being:
1. take the goat/goose over
2. return empty
3. take the wolf/fox over
4. return with the goat/goose
5. take the cabbage/beans over
6. return empty
7. take the goat/goose over

So I was in the shower this morning, and started wondering:
Do you think the people implicated in Jeffrey Epstein's book had a general "Dead men tell no tales" slush fund?
Or did they have to separately organize his assignation?

I'm just imagining that on August 10th there's a big traffic jam of hired killers all running into each other like

some guy's sneaking out of a vent when a guard walks in, sees him, and goes "HALT!" and the vent guy goes "SHIT!", then notices the guard's ill-fitting suit. "Wait, ...Steve? Is that you?"

"Alex! I haven't seen you since the Reno heist! What are you doing here?"
"Same thing as you, looks like."

"I'll be damned. Well, I've already knocked out the guard, you want to let me finish this?"
"Yeah, go ahead. I'll get paid either way."

So someone on IRC mentioned the ending(s) to Zero Wing and I found out there's a cheat code to skip to it. I thought it might have some more "All your base" style dialogue I could put in the generator, but I really wasn't prepared for what ending #1 looked like

ending #2 is some very thin credits

ending #3 is reportedly the "true ending", at least on the European release. The Japanese version has 35 endings.

This one is... more serious? a little?

The other 32 endings are translated here, by

functionally all the japanese endings work like this. you get CONGRATULATIONS and then CATS says something to you.
usually something silly, or possibly the debug menu cheat code

There are lots of problems with ad-tech:

* being spied on all the time means that the people of the 21st century are less able to be their authentic selves;

* any data that is collected and retained will eventually breach, creating untold harms;

1/

* data-collection enables for discriminatory business practices ("digital redlining");

* the huge, tangled hairball of adtech companies siphons lots (maybe even most) of the money that should go creators and media orgs; and

2/

* anti-adblock demands browsers and devices that thwart their owners' wishes, a capability that can be exploited for even more nefarious purposes;

That's all terrible, but it's also IRONIC, since it appears that, in addition to everything else, ad-tech is a fraud, a bezzle.

3/

Bezzle was John Kenneth Galbraith's term for "the magic interval when a confidence trickster knows he has the money he has appropriated but the victim does not yet understand that he has lost it." That is, a rotten log that has yet to be turned over.

Bezzles unwind slowly, then all at once. We've had some important peeks under ad-tech's rotten log, and they're increasing in both intensity and velocity. If you follow @Chronotope, you've had a front-row seat to the

THREAD: Now that @Amazon @awscloud has announced they will no longer host @parler_app, many have speculated that they will just “find another host.”

Here is why that’s not so simple and what it will likely mean for the app’s future. First, let’s look at where things are...

2/ Google and Apple have removed the app from their app stores, effectively terminating growth on mobile devices. People can still access the (not good) web UI until Amazon terminates them today. CEO Matze has said they may be down “up to a week” while they find new hosting.

3/ Translated to English, that’s code for “we have no idea what’s going to happen next.” No US cloud provider (Microsoft, Google, IBM, Digital Ocean) is likely to touch this, as it could be seen as providing material support for sedition. No CEO or counsel wants to get near this.

4/ They could potentially “roll their own” data center by buying servers and putting them in a co-location facility. But that’s a single point of failure, and many colo providers would be just as likely to decline their business. It would be hard and risky to pursue this.

5/ Imagine, after they sweated like pigs to get this hardware all setup, if they get told their colo provider is booting them. That’s a lot of metal to then move somewhere else. Meanwhile, the user base is deteriorating because chaos and dying apps. They will go to other venues.

If you're interested in DB internals, stop what you're doing and watch @CMUDB Quarantine Talk from Nico+Cesar about @SQLServer's Cascades query optimizer: https://t.co/FCdsbHHEaD

Many talks this semester were good. This one is the best. My thread provides key takeaways

[6:50] Microsoft hired Goetz Graffe in the 1990s to help them rewrite original Sybase optimizer into Cascades. This framework is now used across all MSFT DB products (@SQLServer, @cosmosdb, @Azure_Synapse).

[14:43] The optimizer checks whether it has stats it will need before cost-based search. If not, it blocks planning until the DBMS generates them. This is different than other approaches we saw this semester where DBMS says "we'll do it live!" with whatever stats are available.

[21:05] Their Cascades' search starts small/simple and then they make decision on the fly whether to expand search based on the expected query runtime and performance benefit from more search.

[26:33] They explicitly have a property for Halloween Problem. Operators specify whether they protect from it and then optimizer ensures property is satisfied. This is mindblowing. I have never thought about using the optimizer for this but it makes sense.

A thread on teaching live lessons using @MicrosoftTeams Meet Now function where students follow their normal timetable except online - will go into more detail on every point in a blog post later. Have used Teams for live teaching have supported over 100 live lessons since March

1. If you are using the desktop app, check you have the latest version of Teams so that you should have Breakout rooms enabled. Check by clicking your profile picture, then About - I have version 1.3.00.28779. If you have 1.2..., click on check for updates to get the latest

2. Set your entry routine. I get my students to enter with their microphone muted - you can also not allow attendees to unmute by opening the participants list, clicking the ellipsis and selecting that option.

3. Make sure students arrive as attendees - some organisations have this set up to automatically happen that only meeting organizer is the presenter and others are attendees. Can change this in the manage permissions menu to only me if not already set (opens in a web browser).

4. Classroom routine and expectations - first lesson I share my screen and show the students the raise hand function for when they want to ask questions, how to access the chat function and how to react to questions as opposed to typing answers

Data drop! Some numbers, nuggets and trends for bowl season which I find interesting...

Miami has lost 9 of its last 10 bowl games and is 2-10 ATS in its last 12 bowl games. Oklahoma State has covered each of its last four bowl games, three coming as an underdog.

This is the first time since 2011 Texas is favored in a bowl game...

Wisconsin has won five of their last six bowl games with the only loss in that span a one-point loss to Oregon last year in the Rose Bowl. Each of Wake Forest’s last five bowl games have been one-possession games (6, 3, 3, 8, 6)...

Mike Leach coached teams are 1-9 ATS in their last ten bowl games (4-6 SU). Included in those ten games are four outright losses and a 1-7 ATS mark as a favorite. In the last five years, Leach’s teams have averaged 19.6 PPG in bowl games (28 is the high in that span)...

Choosing the Right JavaScript Framework

Thanks for joining me @pluralsight to talk about javascript frameworks. We had 150+ awesome questions, so I'll try to answer the ones I couldn't get to online right here in a tweet stream

Watch the video -->
https://t.co/G7zeiKhXme

Q. Do arrow functions really make dealing with JavaScript's "this" keywords easier?

A. Yes! When using arrow functions, the scope of "this" is effectively passed in from the outer scope. See here in this REPL

Q. Where does Polymer fit in? Is it considered a framework like the others?

A. @Polymer is an excellent way to create web components, which are ideal for creating sets of interactivity that can be shared in web apps.

2/n

Q. Have we gone framework crazy?

A. At one time, quite possibly. A few years back we literally had framework overload. I feel it really has solidified into a few very strong choices.

3/n

Q. [Is] there no more need for @polymer?

A. See my previous question on this ... but in general, I think there is a lot of room for Web Components with frameworks.

💬 I often get Q’s like these:

How did you get your first customers for WIP? How did you grow BetaList’s traffic? Etc.

Makers are looking to reverse-engineer success. I see it everywhere.

I don’t think it works that way and the answers to those questions are mostly useless. 💥

I have built dozens of different products over the last couple of years. The vast majority failed. 😭

Surely if I know the answers to these questions, but still fail over and over again, these answers aren’t that useful. 🤷‍♀️

So what’s a better question to ask? 🤔

99.9% of the questions I receive are about the products that did well. In a way that makes sense, because we quickly forget about those that didn’t succeed.

🧠 This is known as survivorship bias.

Focusing on what survived, while ignoring what made it survive in the first place.

The real question, what you really want to know, is this:

What makes @WIP, @BetaList, and to some extent @AllStartupJobs succeed where my countless other attempts failed?

What separates a failed product 👎 from a successful product 👍?

Honestly, I don’t know. I wish I did.

It’s like Steve Jobs said “I’ll know it when I see it.” 👀

Same is true when we make products. We don’t know upfront what will work. But once we see an inkling of a product that does have potential, it’s not that hard to spot.

Singing the Blues:
Taking Down an Insider Threat

"I had all of the advantages. I was already inside the network. No one suspected me. But they found my hack, kicked me off the network...

...and physically hunted me down."

Many pentests start from the outside, wanting to see how the perimeter might be breached.

This pentest started from the inside. My client wanted to assume they had already been breached, and, if breached, how far could an attacker go.

Could they stop me once I was inside?

So they snuck me in. Disguised me as a new employee. Gave me a work computer, an ID badge, an account in their system... hell, I even had a cubicle w/my assumed name on it.

The only person who knew who I really was was their CISO. Everyone else thought I was Jeremy in Marketing.

During most of the first morning, I completed onboarding, made introductions, and completed menial tasks.

But I had to act quick. I only had a week onsite. I had to hack their network while not raising suspicion.

So I set about it.

You have to understand... most "Internal Pentests" are straight forward. The hard part is breaching the network, but once you're inside, it's a target rich environment. End of Life computers, default passwords, everyone a Local Administrator...

1/ The first 18 months of starting a company is often life or death. I must've made 5 different companies that each failed within 9 mo. 😭 Each time the company failed I figured out what I could do better. Eventually startup #6 got to $40K/mo by month 18. Here’s what I learned...

2/ Stay focused! Ignore things that are a waste of time: meetups & conferences, meetings with no clear agenda, fundraising if you're not fundraising, reading lots of tech media articles, etc. Every week should feel like significant progress in the first year.

3/ Your first 5 hires will be the difference between life or death. Choose carefully. Be picky. Many of the things we do at the company still are a result of those early hires' legacy. Have fun as a tight knit team. It will change & evolve as you get bigger so enjoy this moment.

4/ Growth may be flat for the first 9 months. It's gonna be okay. Almost every company has experienced this: Airbnb had to sell cereal in-between, Slack failed as a gaming company first, Tesla sold only 147 cars after 6 years! You probably won't be an overnight success either.

5/ In the beginning, do customer support yourself. You will learn a lot about why your product sucks. I did 5,000+ support tickets when it was the two of us. Delight customers & fix things fast while you learn. It will help you build an amazing intuition about your customers.
