### Mamas, don't let your babies grow up to be coders, Jensen Huang warns

#### Re: Fail 2

I figured it had trouble with formatting and formatted the equations more nicely.

Result was new nonsense.

#### Fail 2

Solve the following equation system: y=2x-z, y=10x-z-24, 2y=3x-2-z

To solve this system of equations, let's start by expressing yy in terms of xx and zz from the first and third equations:

From the first equation: y=2x−zy=2x−z

From the third equation: y=3x−z−22y=23x−z−2​

Now, we can equate these expressions for yy and solve for xx:

2x−z=3x−z−222x−z=23x−z−2​

4x−2z=3x−z−24x−2z=3x−z−2

4x−3x=2z−z−24x−3x=2z−z−2

x=2z−2x=2z−2

Now that we have xx in terms of zz, let's substitute this expression into one of the original equations to solve for yy.

Using the first equation:

y=2(2z−2)−zy=2(2z−2)−z

y=4z−4−zy=4z−4−z

y=3z−4y=3z−4

Now, we have expressions for both xx and yy in terms of zz. Let's substitute these into the second equation to solve for zz:

3z−4=10(2z−2)−z−243z−4=10(2z−2)−z−24

3z−4=20z−20−z−243z−4=20z−20−z−24

3z−4=19z−443z−4=19z−44

44−4=19z−3z44−4=19z−3z

40=16z40=16z

z=4016z=1640​

z=2.5z=2.5

Now that we have found zz, we can substitute it back into our expressions for xx and yy to find their values.

From x=2z−2x=2z−2:

x=2(2.5)−2x=2(2.5)−2

x=5−2x=5−2

x=3x=3

From y=3z−4y=3z−4:

y=3(2.5)−4y=3(2.5)−4

y=7.5−4y=7.5−4

y=3.5y=3.5

So, the solution to the system of equations is x=3x=3, y=3.5y=3.5, and z=2.5z=2.5

Me: if ypu want to see a proper solution(1,3,5), use wolfram Alpha or implement the Gauss algorithm yourself.

#### AI Nonsense Example

Please compare all aspects of the do 31 and the v22

ChatGPT:

The V-22 Osprey and the Dornier Do 31 are both unique aircraft with VTOL capabilities, but they have notable differences:

Design and Purpose:

V-22 Osprey: Designed for military use, it combines the vertical takeoff and landing (VTOL) capabilities of a helicopter with the speed and range of a fixed-wing aircraft.

Dornier Do 31: Developed as a vertical takeoff and landing (VTOL) transport aircraft primarily for military use, intended to carry troops and equipment.

Configuration:

V-22 Osprey: Features tiltrotor technology, with rotors that can tilt from vertical to horizontal for both vertical takeoff and landing and horizontal flight.

Dornier Do 31: Utilizes a lift jet and lift engines to achieve vertical takeoff and landing, with wing-mounted engines for horizontal flight.

Performance:

V-22 Osprey: Faster and has a longer range compared to the Do 31, making it suitable for a wider range of missions.

Dornier Do 31: Slower and with a shorter range compared to the V-22, but it was designed for specific military transport needs.

Service History:

V-22 Osprey: Used by the United States Marine Corps, Air Force, and Navy for various missions including troop transport, medevac, and special operations.

Dornier Do 31: The Do 31 program was canceled after limited testing and development, so it never entered operational service.

Technological Legacy:

V-22 Osprey: Represents a successful implementation of tiltrotor technology and has been in active service for decades.

Dornier Do 31: Though the Do 31 program was canceled, it contributed to the development of VTOL aircraft technology, particularly in Germany and Europe.

Overall, while both aircraft aimed to fulfill similar vertical takeoff and landing capabilities, the V-22 Osprey has seen significant operational success and remains in service, while the Dornier Do 31 did not progress beyond the prototype stage

Me: apparently the quality level changes often. This time it correctly described the main difference. But it has one big factual error(speed), which clearly demonstrates the worm intelligence. The Do 31 is the speedier concept, as it does not have silly huge rotors. Its a real jet, unlike the V-22.

Also, not a single word about the horrible safety record of the V-22. It has killed more than 40 soldiers in accidents to date. Almost the definition of "pressed into service without reason"

#### Monetized Nonsense

It is not as bad as "you will die if you do not take this quick&dirty vaccine"*, but surely the motivation is identical: spin the money wheel for Nvidia, a major producer of ANN processors.

Current AIs have the complexity of a worm brain - about 10000 neurons.

Humans have in the order of 100 billion neurons. Even cats and dogs have in the order of 1 billion neurons, which is why we can have a deep, good relationship with them. We see their creativity, their expression of love, their kindness, their acrobatic skills and many more things.

Dont believe a word of Huang, software engineering can be one of the most demanding intellectual endeavours.

Just ask the AI to perform a task that it had not inside the training material and it will fail spectacularly. E.g. solve a linear equation system, write the complete Enigma source, compare+judge the V22 and the Do31. It will fail on all of these tasks.

* very much the opposite was true, statistically speaking

#### Steve KIRSCH

He is the inventor of the optical mouse and he analyzed the data:

Covid vaccination killed 10x more people than it saved.

Having seen CDC VAERS data I agree with KIRSCH.

### EU wants to make undersea internet cables more resilient

#### Re: Undersea Defence

I recall reading "a single helo with active sonsor can surveill the brittany channel".

So it would probably be just 100 active sensors to be moored and connected.

How many passive sonars ? We cannot blast the ocean all times without driving fish and sea mammals crazy.

#### Re: Union of Clueless and Weak

That was before 1945 :-)

#### Re: Union of Clueless and Weak

The EU and her predecessors.

#### Re: Undersea Defence

It looks like 30km or even more can be the spacing of the active sonar. This makes everything more affordable/feasible.

https://en.wikipedia.org/wiki/HELRAS

https://en.wikipedia.org/wiki/Sonar

#### Undersea Defence

Parallel to the cable routes, pipelines should be a network of listening devices, similar to the SOSUS system. Also, active sensors(similar to the helicopter based active sonar) should be moored and connected along these routes. One sensor for each 3kms or so.

Any intruder could then be immediately "pinged" by the active sonar in order to scare him away.

If that is not good enough, an armed patrol aircraft (e.g. A320 MPA) must be dispatched to scare away the submarine.

All not cheap, but given the economic importance of these cables, it probably is worth it.

#### SACEUR Too Weak, European General Staff Needed

SACEUR has proven to be too weak in the face of the Russian and the Turkish threats to the EU.

For example, SACEUR could not mount a full-scale European Air Defence Exercise when Luftwaffe wanted this to happen. SACEUR should have pulled Spain, Italy, France, Britain, Germany, Poland, Romania and Greece together in a Single Unified Force for at least one week of exercise.

Instead, what we got was a half-baked show with part-time pilots from America and second-rate French participation.

So, we need to take matters in our own hands and set up a EuGenStaff, comprised of the top European officers. Each nation sends one man and the staff then elects a chairman from their group. Voting power in the EuGenStaff is determined by national defence expenditure or a similar metric.

Whenever the Turks, the Russians or anyone else poses a threat, EuGenStaff comes together in order to command all of their forces as a single, unified force.

#### Satcom

Another option is to plan for accessing U.S. data centers and services via much more narrowband satellite services such as StarLink or Intelsat.

Try out your plan too see whether it really works as intended !

#### Prepare For Worst Case

Data stored in U.S. data centers might not be accessible for a bunch of weeks, if the security situation deteriorates for European companies.

A single submarine can do lots of damage in the Atlantic, before she is detected and neutralized.

It takes a few weeks to repair all damage.

Store all mission-critical data in data centers with landline connections to your company. Do not make your core business dependent on U.S. service providers who can only provide the service from U.S. data centers.

#### Union of Clueless and Weak

They can only express the problem, but no word about the solution. Typical of the EU drones.

The ugly truth about seaborne infrastructure is that it is hard to protect at large scale.

What can be done is to threaten retribution to any offender. "If you blow up my stuff, I will blow up some of your assets".

For that you need COJONES, something the EU is short of since 1945.

Actually, you can play Divide Et Impera with the EU nations and Britain.

Ankara, Moscow and others know this very well.

### Google co-founder Brin named a defendant in wrongful death complaint

#### PennyPinch Engineering

One should assume this vital system would be tested in a "workshop flight" by the installers. Over land, close to emergency airfields.

Secondly, on the flight to Hawaii, the pilots should have tried the bladder pumping system while their main tanks were 50% or more full. Then they could have turned around safely on malfunction.

Thirdly, Mr Brin should look the families in the eye, say sorry, share some tears and compensate them for the loss of their men.

He has got the money.

Finally, workshop errors happen in aircraft engineering. I know of such horrible stories from my father, a Luftwaffe mechanic. Mr Brin would definitely not be the first to be related to an aircraft crash.

### Trident missile test a damp squib after rocket goes 'plop,' fails to ignite

#### Re: Tactical Use

They still use teleprinters, as they require minimal hackable tech.

#### Way Too Much Work

<Cynicism>

Just hire a P.R. expert, who will explain that on average, Trident is 90% successful while the Russian competitor just manages 50%.

That is 10 times less expensive than an actual launch.

</Cynicsim>

#### Nah

It is a conspiracy of the lizard people out of New Swabia. They suffer a shortage of propellant for their Nazi flying saucers and have obtained it this way !

#### Statistics

The Americans claim 90% of their 191 Trident test flights have been successful. They also claim Russia has a success rate of just 50%.

Now, even a 30% success rate would constitute a credible threat, so this is indeed a storm in a teacup.

Having said that, the Minister of defence should demand reruns until the system demonstrates success.

Quite sure there is a safety system inside the missile, which ensures the rocket is only ignited when safely off the submarine. A microcontroller plus inertial sensors can go a long way to achieve this.

#### Mind Messing

Superpowers always want to use information to get their objectives done.

They can explain to you essentially everything if you follow their "tortured logic".

A day later they will explain the opposite thing because something has changed, including a change of their own plans and goals.

#### Inertial Nav

With electronic/SW control and inertial sensors it should be assumed that a modern torpedo knows its approximate position relative to the submarine at all times, even if the ejection from the tube went wrong somehow.

Then it is a matter of "fencing" to arm the warhead only when the torpedo is inside the "kill zone".

Same reasoning for SLBMs to ensure they fire the rocket only when they are clearly out of the water.

#### Tactical Use

One can still use a strategic weapon to stop e.g. a tank breakthrough.

Besides Germany has Geschwader 33 plus B-61 nukes. Italy and Turkey have those, too. All it takes is the proper coded-secured command telegram with the nuke's unlock code inside.

Plenty of options inside the Flexible Response Doctrine.

We must simply show the Moscovites the rope for their self-inflicted hanging. Then they will change subject in a second.

#### Indeed

Many officers onboard British submarines must agree that a nuclear strike is justified. For additional safety, coordinates are not loaded and must first be pulled from a plan inside a safe.

Justification either comes from high command by coded/secured radio or from the observation that Britain has been totally nuked. All communication channels(HF, VHF scatter, satcom) to other units dead.BBC no longer transmitting. Nuclear explosions recorded by sonar en masse.

Only THEN the ships crew are allowed to strike themselves.

#### FALSE

The Russians also perform regular test flights of all missile types.

There is no single person who can launch an armed nuclear missile in Russia by his own "mad desire". Neither is it possible in the U.S. or the U.K. or France.

Moscow wants to play above their weight class by means of these insane, suicidal threats.

Whe should kindly ask them to check into a hospital for a few weeks. Never take the threat for real.

### How to weaponize LLMs to auto-hijack websites

#### Glas Half Full

As always in the security field, defenders need to understand offensive tactics.

So the defenders("white hat hackers") should indeed use these AI tools to try to break into the systems to be protected. Also see "red team".

Having said that, AI is still "worm intelligence"(based on complexity and my real-world testing results) and the advanced tactics will still be developed by humans.

AI is essentially a neat form of automation of existing stuff. All the problems such as "hallucination" and "posing as perfect" will apply.

### Billions lost to fraud and error during UK's pandemic spending spree

#### Re: The REAL CRIME

Steve Kirsch (inventor of the optical mouse) says the Covid vaccine killed 10 persons for saving one.

Given the VAERS numbers, I consider this as a credible statement.

A huge failure of police, security and health agencies. Corrupted.

#### Re: The REAL CRIME

My point is that the adverse effects were horribly high, 10000 times worse than e.g. long established measels vaccine.

#### Re: The REAL CRIME

Antifa in pay of PharmaMafia ?

#### Why ?

The sources I quote are both part of U.S.G.

#### Re: The REAL CRIME

If you read carefully I write only about the quick+dirty Covid vaccines.

#### Re: The REAL CRIME

Given that all you can do is insult the messenger, I take it as a validation of my message. Thanks.

#### Re: The REAL CRIME

The stories about wireless transmitters inside the C-vaccine were designed to either discredit any disapproval, or they came from a hostile power in order to stir up dissent.

I never wrote about them here or quoted something of the like.

In my circle of friends one man almost died from heart inflammation after the C-vaccincation. It was clearly a quick+dirty medical product.

### Open source's new mission: To boldly go where no software has gone before

#### False

You will find that Mr Maduro is a corrupt man who likes to be bribed when he makes the decision to buy your software.

Corruption thrives in tyrannies.

#### Yay, Socialism

It would certainly work better NEXT TIME.

It failed for machines,velectronics and even food producion, but will win on software !

Irony off.

Socialism is for the lazies, the criminals and the dumb. They can then steal from the others until the last hard working man got the signal and joins the first group. Then starvation starts. See Venezuela.

#### So ?

Run your own server. Either at DSL modem or at Hetzner for 5 euros per month.

Stop using the gold plated WallSt. cages.

#### Re: Only for a specific type of open source, and only from a certain viewpoint

Arent there tons of other BSD Unix based commercial appliances out there ? Firewalls, file servers, routers,...

### Drowning in code: The ever-growing problem of ever-growing codebases

#### Re: UI standardised ?

Try OpenOffice with RPI. Lightning !

#### Re: "Late in Wirth's career, he became a passionate advocate of small software."

Partialliy right. Language should not contain IO facilities.

Wrong in that Pascal was just educational. Major systems like HP MPE and Apple Lisa were done in Pascal variants.

MPE grew into mainframe size with 16 CPUs and 10000 character terminals/userd per machine

#### m4 macro processor

Wirth was right not to add a macro processor.

Code generation by macro processor or otherwise should be left to external tools.

That would also be the unix spirit.

#### Re: 10ms

Did you ever bother to install Thunderbird for her ?

#### Re: Spot on.

What do you expect of a low level soldier ?

Skills of a Franco ?

#### Re: users?

Just make sure not to turn it into Maoist self-accusation.

Then of course each and every good engineer will be open to positive criticism.

Great men know that great work is always a compromise betwern different goals. One goal is to deliver in finite time and by finite means.

If you want to do something truly new+useful, keep the rest as simple as possible. That does not mean you are lazy. Rather, you are focused.

### From browser brat to backend boss: Will WASM win the web wars?

#### Sandboxing using Linux Security Modules, AppArmor etc

You can lock down any Linux binary using the LSM system to the point where every kernel call is intercepted and tested for correctness. The only real benefit of WASM is that it abstracts the CPU instruction set.

#### WASM == Portable Assembly

The WASM model is much more basic and lighweight than the JVM model. JVM forces GC based memory management. WASM leaves it to the compiler+runtime. You can have GC or ARC with WASM.

Which is great, because you can now run ANY language and runtime efficiently in WASM.

Having said that, an x86 program plus an AppArmor profile can almost do the same as WASM does. At a bit higher speed.

### Rust can help make software secure – but it's no cure-all

#### Re: Curious

I recall reading that some JVMs do use Stack Allocation of memory that is requested with the "new" operator when this is safe.

The problem of GC is its inefficiency. GC does waste memory for very basic reasons and it interrupts the program at unpredictable points in time.

That is why Rust and Sappeur use reference counting(ARC). With ARC, the developer can finely control the deallocation of heap objects. This is bought by the fact that ARC cannot collect cycles of trash. Developer must first break the cycles with explicit code.

#### FALSE

What you describe as "rookie error" exists in ANY large C program from VxWorks to Windows, to all Unix variants. First time the Unix tools such as sed, grep, uniq were run under valgrind, quite a few memory errors were detected. If your claim were true, Unix would have been written by rookies and then never touched for decades. All of which is untrue.

Likewise, the VxWorks TCP/IP stack had several remotely exploitable memory bugs. Windows and Linux kernel memory bugs existed in the hundreds and probably some of them are still undiscovered. OpenSSL's horrible memory management practices are legion.

In other words: your description is whitewashing the situation. It is the old "if developers were only perfect" fallacy. They are not. They have bad days. They must deliver to a deadline. They have a cold. They needed a beer too much the evening before they created a bug.

#### Re: RAII

You could say that almost all types of Resource Handling is easier if you have synchronous destructors, as C++ and Sappeur have. Destructors are a gem !

In Java, Go and C# the developer needs to create loads of extra code to handle that.

#### Re: "Rust will stop you using data after it's been freed"

Rust and Sappeur are the first languages really dealing with the idea of "memory shared between threads in a robust manner". C and C++ came from the world of single-threaded execution and have still not addressed the problem of "accidental sharing between threads".
