I have always protected my systems by keeping up to date system images and data backups, but I often wondered what would happen if some clever hacker developed a virus that corrupts the computer's BIOS. To the best of my knowledge, the BIOS is saved in a hardware chip on the computer's main board. Since the BIOS loads the operating system, if the BIOS is corrupted there's not much you can do about such a virus.
Yes, I have a utility from Dell that will reflash the BIOS chip, but since the BIOS virus controls the operating system, will it allow Windows to reflash the BIOS chip? I doubt it!
The main mechanism used by this malware is to corrupt the manufacturer's logo that first shows on startup, before Windows is loaded. I find this scary, but I have one point in my favor: I only bought Dell devices for my family. Here is a quote from the article below:
Quote: Many devices sold by Dell aren't directly exploitable because the image files are protected by Intel Boot Guard, making it impossible to be replaced, even during a physical attack.

Some motherboards, such as some Gigabytes, comes with a backup BIOS which can't be flashed. So, if the machine is mission critical then it's worth considering a board that has one. You can literally just boot with the backup BIOS and reflash the main one.

Windows has zero say-so on whether or not you can flash the BIOS. At best it can restart the computer. Any flashing software isn't using the Windows kernel, API, etc.
To your point though, a virus could in theory prevent the reflashing (not sure though). That being said, these days a BIOS is stored on EEPROMs, so nothing can prevent you from physically taking the chip out of the computer and rewriting a good BIOS on it before putting the chip back in the computer. Sure you'd have to soldier/desolder, but it would work.

The logo fail thing has been around for a while, just FYI. There may be a new instance of this that just surfaced, but it's nothing new.
Secure Boot will help mitigate some issues with this. It's not perfect since a virus could bypass that too, but it'll at least make it a bit harder for the virus.
All scare tactics aside, this is one of those cases where an ounce of prevention is worth a pound of cure though. If a machine is mission critical it should be behind a DMZ/firewall/something with locked down restrictions.

I've stubbornly use MBR on all my machines for concern the real reason for UEFI is so Microsoft can control from where your pc loads it's boot code such as Azure someday and viola Subscription Windows. I don't use 11 at all and only 10 on my MBR DAW because the audio software I use "requires" it. So UEFI is exploited, bummer drag.

... I found this promising: Alien: Romulus | Official Trailer - YouTube[^] - very much looks like it's "back to the roots" rather than the "oh gawd not again" of Prometheus and Covenant.
Of course, it could be another case of "trailer-with-all-the-good-bits" and nothing left for the actual movie, but we can hope.

One of the problems with teaching myself stuff is I end up with my own lexicon and orthography for whatever is I'm dealing with, and then I run into walls trying to come up with solutions where I need input or help from other people.
Having taught myself C++ and generic programming I'm facing one of those issues right now. I'm not sure it can be expressed in C++, and if so, it's through some magic like SFINAE (which i don't understand either)
I simply don't have the language necessary to ask the question.

I’ve learned programming all by myself too.
Programming is associated with math. Everyone had the mindset “Math and programming go hand in hand”. I didn’t understand why people thought this way until very recently when I stumbled upon the problem of writing a serious steering algorithm for my strategy game. To get the things I want working I’m facing the challenge of learning the math lessons I skipped over when I was in high school. You don’t need math to learn a programming language that’s true. However you won’t get too far if you don’t know math in a complex program.

I've got a bit of a "not invented here syndrome" (other people's work often just doesn't cut it) and so I created my own time registration and invoicing software for use at my company.
Usual story, it started out as Excel, migrated to a database, then a simple .NET Core application born from hopes and dreams of which I've realized maybe a third.
So this application works really well for me and my coworkers, but it has some quirks and lots of stuff I don't use or haven't finished...
Decided to fix them, then decided to completely modernize it, then decided to cut the fluff, then decided to add features I was really missing...
And a business partner of mine has been nagging me to let him use it for years now so I'm making it multi-tenant (he's my best salesman, bringing in two of my best clients, and I don't even pay him, so I guess I owe him one).
Haven't had so much fun programming in years!
I've been programming instead of gaming, so that's really saying something! 
And then when all was good and well my girlfriend suddenly broke up with me this week (we weren't in a fight or anything, but she just lost her romantic feelings for me and thought of me more as a good friend) 
It's only been three days, and usually I wouldn't even have seen her in that time either, but I'm already missing her and somehow the house feels empty even though she was around only about half of the time.
Well, sh*t happens and I've been through breakups before so I'll probably survive this one as well.
At least I've found a sort of new purpose in my software and I'm not bored 
Oh yeah, and I've been losing weight (after gaining 10 kg in about a year time! ) and this morning I was "suddenly" 1.5 kg lighter (after watching my eating and hiking and biking for weeks, mind you)
I've already lost about 5 kg in as many weeks (really going for it)!
I guess with my girlfriend breaking up I've even lost 65 kg (quote Ross from Friends: "ah, humor based on my pain, ah, ha, ha")

We have lived a parallel life up to the point where your girlfriend left.
I found myself in a sole proprietor retail given quickbooks desktop and a laser printer with the un-spoken words of ok, get after it.
Oh, hell no and got to writing my own POS webapp to support daily life in the little shop.
It also grew the same way as yours, going multi-tenant along the way etc.
Best of blessing going forward bro.

1,000%. If you're a small business, reinventing the wheel while getting started is lacking focus at beast and a waste of resources at worst.

I learned Classic ASP over 23 years ago writing a little customer lookup utility. Over the years, it grew to handle other stuff like billing, customer portal, bug tracking/reporting, and customer contacts (remotes/issues/offline work, etc.) That's the nice thing about 'rolling your own'.

Sort of, I had to ask the Azure problem to my customer because we don't have full access to their network and DNS, so they should be the ones to fix it.
The localhost issue was a weird one.
I attributed the problems to differences in different (local?) DNS servers and fixed it by adding the following to my hosts file:
127.0.0.1 sub1.localhost
127.0.0.1 sub2.localhost So it's fixed, but not the satisfying sort

You sure that's the best use of your time for a small business, man? QBO will handle both of these and just about any CPA can work with QBO exports. Remember, just because you can do something, doesn't mean you always should.

Sorry to hear that buddy. Not sure if you wanna hear my thoughts on the matter or just need to let it out. So, I'll shut up and just say sorry to hear that.

Niiiice. I'm in a similar boat. Let myself get way out of shape. You're human. At least you're fixing it man.

I'm pretty sure it's not, but time you enjoy wasting is not wasted time 
I've looked at some alternatives, but they get pretty expensive once you want time registration and invoicing and have employees.
And I'm doing with the time I've got to spare, so mainly instead of gaming.
It's a bit of a "playground" for new tech and upgrades too, though.
So I'm updating some components and checking if they're not breaking anything so we can update them for customers with minimum risk when the time comes.
Don't worry, there's still plenty of stuff I'm not doing myself

Not really, well enough equipped emotionally and rationally to deal with this.

In fact, my girlfriend was a bit of the reason I gained so much in the first place.
She likes candy and bought it.
I like it too, so I never bought it, but when she bought it I just couldn't help myself (while she could, so more for me!) 
I've been pretty much stable for years until I met her

This is what the Boeing CEO has said in the Senate hearing. Boeing CEO Dave Calhoun faces grilling at Senate hearing - YouTube [^]
Having a non-engineer as the CEO of a life-critical high-tech engineering company; with that CEO having senior engineers advising him on technical matters - seems to be sub-optimal, isn't it? What value can such a CEO add in say, a design review meeting? What engineering judgement can he have?
IMHO, it should be the other way around - the CEO of such an engineering company should be an engineer, with senior business people advising him/her on stock market and other business matters.
What say you?

I say "Yay". However were not both NASA Shuttle disasters the result of decisions by trained engineers.
|
|
|
|
|
Agree.
However one point. NASA missions are kindof exploratory/research type of missions, and not as commercial as passenger aviation.
Research has its own risks/rewards, and not always guaranteed of success.
Whereas this is time tested, more than a century old aviation industry, where they are expected to (at least) maintain status quo, as regards passenger safety.

Businesses aren't about the products - they are about the units. A CEO markets units, he doesn't really care what they are units of.
Sadly, the accountants are in charge of most businesses, and they know "the cost of everything and the value of nothing" (the late, great pTerry).

All accountants know is how to cut costs and so boost the next quaterly dividend and consequently their bonus. Their thinking is very short term. They don't appreciate what such short term thinking is doing to the company in the long term.

If the CEO was such a great engineer the role of CEO would be wasted on him.
Instead, it's his job to be grilled at Senate hearings when his senior engineers and advisers mess up.
|
|
|
|

In comparison, Pichai also faces Senate meetings. Though a Metallurgical Engineer by training, he has worked extensively on software, for which he is accountable. He has a strong engineering background.
Calhoun, on the other hand, I'm not sure whether he's worked on stress/fatigue/fracture/impact/dynamics kind of computations, which are so very critical in aerospace.

The problem with dev/engineer types is they think they know everything, when in actuality nothing could be further from the truth. They generally suck at dealing with people, are immature, lack social skills. I could go on. This is not to say, non devs/engineers are inherently any better at this. It's to say that qualification alone does not a good CEO make.
The fact is, there's more than one type of intelligence. Denying that is no different than being a child who refuses to grow up and see the world while mentally living in their mom's basement. Denying that is no different than spending your entire life behind a computer thinking you're God, etc. because there's nobody else in your "world" to say otherwise.
Now, can an engineer make a good CEO? Sure. But a good CEO (or anyone) cannot know everything in the world. They need to be big picture people who can see trends, patterns, etc. that few can. The vast, vast majority of engineers are just the opposite - they focus on the minute details. Anyone can learn to be better at anything, but if spending 20+ years on CP has taught me anything is that very few people go outside their comfort zone and a lot of devs/engineers have lousy social skills.
Point is, only an engineer with zero life experience will think an engineer makes the best CEOs based on that qualification alone. If this sounds harsh, it's because you're thinking like an engineer and can't handle the truth. And senior business people tend to be more operations than big picture people. A good CEO brings people together, is a big picture person, has a vision with an idea of how the future will unfold. Operations would be more of a COO if anything for a company that size.
And yes, there are outliers. This is clearly a generalization.
This is not to say, non devs/engineers are intrinsically more mature. There are plenty of immature people in the world in various degrees. I'm just focusing on that group because we're on CP.
And no, this does not mean I think the Boeing CEO is good at their job.
And this doesn't mean a CEO should be ignorant of tech, the product, etc. They should have an understanding, but not necessarily on the same level as an engineer getting their hands dirty daily.
