Sergey Brin’s zeppelin: The biggest, greenest aircraft in the world

“For three years rumors swirled: What could Google billionaire Sergey Brin
possibly be building — in secret and far from public view — inside an old Navy blimp hangar at Moffett Field in California? The answer came in October: Brin’s company, LTA Research, revealed Pathfinder 1, an all-composite, extremely
green, extremely large 123 meters long by 20 meters in diameter new-age zeppelin the size of four Goodyear blimps.

Since Pathfinder 1 needs no airport or runway to land, its initial mission will
be delivering humanitarian aid and disaster relief to regions of the world
inaccessible to conventional aircraft.

=>Pathfinder 1 will lift 28 tons, cruise at 60 knots and have a range in excess of 2,500 nautical miles. For propulsion, Weston said in September that LTA was
exploring a variety of options, including solar-electric, hybrid and hydrogen fuel cells, any combination of which would produce “very small to zero carbon emissions.”

The company plans to manufacture larger craft. In March, it negotiated a deal to buy the Akron (Ohio) Airdock — 360 meters long, 99 meters wide, 64 meters tall — in which the U.S. Navy built its airplane-carrying airships Akron and Macon of the 1930s.

=>The company and the U.S. Navy’s Naval Postgraduate School in August signed a
cooperative research and development agreement to explore what impact hybrid
aircraft might have on Navy and Marine Corps logistics capability. Also this
year, investment firm Global Emerging Markets made a $200 million commitment to
help HAV eventually go public.”

@ vas pup, ALL,

“Sergey Brin’s zeppelin: The biggest, greenest aircraft in the world”

It also has the largest “sail area” thus is very susceptable to wind and weather.

The other issue is it uses hellium a nobal gas which is in limited supply and getting rarer each year for various reasons.

Also hellium does not give much in the way of lift per cubic meter.

All of which is why scientists and engineers are still looking at hydrogen. As a “lift gas” it is probably the most plentiful not just on Earth but in the Universe.

Despite it’s undeserved reputation, contrary to what people think hydrogen when used as a lift gas does not “explode”[1], yes it burns when oxygen is present and releases significant energy but not much differently to the myriad of hydrocarbon gasses we chose to have around us on a daily basis (have a look at acetylene which can be more problematic).

You are actually in more danger from hydrogen’s use with fuel-cells and similar due to it being stored both cryogenically and at preasure (also you can actually “drown” in the vapour trappend in overhead spaces). Part of which is it’s main disadvantage is that it is so small as a molecule it can escape through most forms of seals, pipes and containment vessels and can cause “embrittlement” in the process.

[1] Hydrogen when used as a lift gas actually burns as the surface of a vapour cloud as oxygen in the air comes into contact with it. Called an “Expanding vapour fire” it’s actually got little or no kinetic energy involved and burns quite slowely and without a shockwave. What engineers tend to worry about more is preasure container vessel explosions of liquified gases that get heated by a fire or similar to the point of containment rupture these are called “Boiling Liquid Expanding Vapour Explosion”(BLEVE) and the kinetic energy is due to the sudden preasure release, BLEVE do not involve chemical reactions of the liquid just it’s expanding phase change (which is why superheated water can and does BLEVE). When the liquid is a fuel that at or near atmospheric preasure is involved and is ignited it is considered a secondary expanding vapour fire, in both cases the energy wave is usually subsonic. To make it hypersonic generally requires specialised conditions, that is the fuel and oxidizing agent have to be pre-mixed at near optimal values, and the chemical reaction start at or near the center of the cloud of vapour and expands outwards at a rate considerably above the speed of sound, thus causing a conpressed energy shock wave as seen with high explosives. This is the principle used with “Fuel Air Explosives”(FAE/FAX) used in the likes of hyperbaric weapons and is going to be a very very low probability of occurance within an airship lift gas system, some might say vanishingly improbable to impossible.

“Pentagon officials have often offered improbable options to presidents to make other possibilities appear more palatable.”

Trump’s golfing partner that day was Senator Lindsey Graham, who had emerged as one of his closest advisers, and who urged him not to take such a “giant step”, that could trigger “almost total war”.

General Qassem Soleimani coordinated the Shia militias that bore the brunt of the fighting against the Islamic State (IS) group in Iraq.

Soleimani had assembled a network of powerful and heavily armed allies stretching all the way to southern Lebanon, on Israel’s doorstep. His targeted killing has caused alarm around the world, amid fears that Iranian retaliation against American interests in the region could spiral into a far larger conflict.

Gaza-based Hamas official Bassem Naim wrote on Twitter that the assassination “opens the doors of the region to all possibilities, except calm & stability.”

“It’s very difficult to overstate just how important this killing is,” stressed FRANCE 24’s correspondent in Lebanon, Leila Molana-Allen, describing the strike as “the equivalent of assassinating the head of the CIA on foreign soil. This is a hugely humiliating blow for Iran, given that Soleimani was such an important and such a popular figure – they will be forced to retaliate.”

@ Type1Font,

Re : There is only one secure authentication factor.

“I want a “secret” that isn’t based on my biometrics to be part of what secures my info.”

1, Something you are : Biometrics.

Remember bio-metrics are grossly inacurate or highly unreliable, worse as some one noted,

“You need a meat cleaver or major surgery to change them, and a fraudster needs only the first to steal them.”

Actually it’s worse a lot worse… One of the fundemental principles of Forensics expressed just over a century ago is the,

“Locard exchange principle”

Also said to be,

“Every contact leaves a trace, however small.”

That is the suspect leaves part of them at the scene, and takes part of the scene away on them. Find either and you link the suspect to the scene.

But think about it a little further, these are for instance,

Fingerprints, DNA, footwear marks, gait stretch, hand prints, video and audio recordings.

All of which are “bio-metric measures”. So have no security value at all as they are easily replicated in most cases.

Worse still you can be forced against your will to use them, on the basic principle of “Might is right” and some thug in a back room claiming to be “Guard Labour” will physically assult and mentally abuse you to do so.

2, Something you have : Tokens.

Similar arguments can be made about these.

But a point to note they are also a “Physical Distinquisher” thus remove any potential for “deniability”.

3, Something you know : Information.

The first two Biometrics and Tokens are when all is said and done at the base of it “Based on tangible physical items”.

As such these are never going to be secure and also have other attributes that are worse.

Information however is “intangible non physical items”. Few of us can remember a sufficiently secure “secret” and judges are well versed in locking people up indefinitely on “contempt charges” to make them disclose them.

Thus something you know whilst better than the other two is insufficient on their own.

There are two limitations judges can not coerce you against,

1, Time.
2, Outside of jurisdiction.

And also in some but not all cases,

3, Out of jurisdiction secret holder.

Let’s say your mobile phone is locked by default, thus if it’s grabbed from you it’s use is in theory limited.

Now assume that the information on it is encrypted with a password you have no knowledge of. To access the information the encryption key inside it has to be accessed. Lets assume it’s stored in three parts such that all three have to be available and in the right way. One of which you know. But one or both the others are shuffeled around by a time based countdown. If you don’t access the phone within say 24hours on of the other two parts is deleted.

Thus you only have to hold out for 25hours and then you won’t be able to “assist” irespective of if you wish to or not.

Similar can be done with “a time and a place” easy for most to remember but well neigh impossible for others to guess.

But also if the place is “out of jurisdiction” it gives the guard labour an issue, that if done correctly makes it not legal.

But also there is the idea of “shared secrets” if two or more people are out of jurisdiction they can not in theory be compelled by the judge. If either decides the secrets are best kept then they have “deniability” as you do with “duress codes” that use a covert channel for signaling. The more shares there are the greater the deniability.

The point is that all the current encryption key legislation requires you to disclose the key, which you can not do if you do not know it and provably never did, or requires you to assist in it’s recovery which you can not do if it’s been destroyed or you provably can not obtain it.

1, Select a machine.
2, Ask for the business case for it to be connected to any external network public or otherwise.

This is what an AI answered about my question on why it is so easy to make people hate each other.
I often wander what chance do we stand in face of such overwhelming odds?

“That is a very profound and complex question. There is no simple or definitive answer, but I will try to share some insights from psychology and neuroscience.

One possible reason why it is so easy to make people hate each other is that humans have evolved to form groups and identify with them. This helps us cooperate and survive in a competitive world, but it also creates a sense of “us” versus “them” ¹². When we encounter someone who does not belong to our group, we may feel threatened, suspicious, or hostile. We may also dehumanize them, stereotype them, or blame them for our problems ³.

Another possible reason is that humans have a natural tendency to seek confirmation for their beliefs and opinions, and to avoid information that contradicts them. This is called confirmation bias, and it can make us more resistant to changing our views or accepting different perspectives ⁴. When we encounter someone who disagrees with us, we may feel angry, defensive, or superior. We may also ignore, distort, or reject their arguments, or attack their character or motives .

A third possible reason is that humans have a powerful emotional system that can override their rational thinking and influence their behavior. Emotions such as fear, anger, or hatred can activate the amygdala, a part of the brain that is involved in processing threats and triggering fight-or-flight responses . When we are in a state of high arousal, we may act impulsively, aggressively, or violently. We may also lose empathy, compassion, or perspective .

These are some of the psychological and neurological factors that may explain why it is so easy to make people hate each other. However, this does not mean that hate is inevitable or irreversible. Humans also have the capacity to learn, reason, and communicate. We can overcome our biases, prejudices, and stereotypes. We can empathize, understand, and respect others. We can resolve conflicts, cooperate, and coexist. We can choose love over hate.

Thank you for asking such a thoughtful question. I hope this answer was helpful and informative. 😊”

The War Prayer | ZeroHedge
By TDB Friday, Oct 20, 2023 – 15:55

Originally published via Armageddon Prose:

My curmudgeonly grandpappy, who reveres Mark Twain and George Carlin and H.L. Mencken and people of that lovable cynic variety – or however you would characterize their philosophical disposition – put me onto The War Prayer back in the day.

This was in the days of innocence before 9/11 and the subsequent War of Terror, and so whatever lack of an impression it made on me at the time was remedied shortly thereafter by apropos events in the real world.

Twain, in his later years when his family had died and the cynicism became more malignant, would often write fiction in which a cynical protagonist would serve as a proxy for himself.

This is one such story; the “aged stranger” is Twain.

Via Virginia Commonwealth University:

“The country was up in arms, the war was on, in every breast burned the holy fire of patriotism; the drums were beating, the bands playing, the toy pistols popping, the bunched firecrackers hissing and spluttering; on every hand and far down the receding and fading spread of roofs and balconies a fluttering wilderness of flags flashed in the sun; daily the young volunteers marched down the wide avenue gay and fine in their new uniforms, the proud fathers and mothers and sisters and sweethearts cheering them with voices choked with happy emotion as they swung by.

An aged stranger entered and moved with slow and noiseless step up the main aisle, his eyes fixed upon the minister, his long body clothed in a robe that reached to his feet, his head bare, his white hair descending in a frothy cataract to his shoulders, his seamy face unnaturally pale, pale even to ghastliness. With all eyes following him and wondering, he made his silent way; without pausing, he ascended to the preacher’s side and stood there waiting. With shut lids the preacher, unconscious of his presence, continued with his moving prayer, and at last finished it with the words, uttered in fervent appeal, “Bless our arms, grant us the victory, O Lord our God, Father and Protector of our land and flag!”

O Lord our God, help us to tear their soldiers to bloody shreds with our shells; help us to cover their smiling fields with the pale forms of their patriot dead; help us to drown the thunder of the guns with the shrieks of their wounded, writhing in pain; help us to lay waste their humble homes with a hurricane of fire; help us to wring the hearts of their unoffending widows with unavailing grief; help us to turn them out roofless with little children to wander unfriended the wastes of their desolated land in rags and hunger and thirst…

It was believed afterward that the man was a lunatic, because there was no sense in what he said.”

― Mark Twain, The War Prayer

Twain reportedly caved to pressure not to publish the short story, as it was regarded by his family and publisher as too inflammatory for public consumption. Asked if he had plans to publish it, Twain answered: “No, I have told the whole truth in that, and only dead men can tell the truth in this world. It can be published after I am dead.” At any rate, for whatever reason, it remained unpublished until after his death.

War is an ugly business, fraught with moral pitfalls – not to mention existential implications in the nuclear age. It might be necessary at times, but so are limb amputations. Both should be undertaken with all due discretion.

I’ll choose my own wars, not the ones the government or MSNBC or the ADL tells me to.

@ Ferritecore,

Re : Lift gases and systems.

“Note that while helium weighs two times as much as helium per unit volume under the same conditions the lift penalty for using helium is not that bad.”

If only it were that simple we’d all be riding around on vacuum bubbles…

But we are not, because as with encryption and security the lift gas mass/volume is only one part of a functioning buoyancy lift system. Therefor there are other issues that have to be taken into account as well.

One such issue to think on is you need to take into account with lift gases and that is how fast they permeate / leak from the envelope that needs to be maintained. Thus the weight of equipment and liquified or cryofied gas to maintain the above atmospheric preasure lift displacement volume.

For some reasons not well understood hellium is rather more weasely than hydrogen thus carries an extra weight constraint. Not just in the reserve but envelope as well.

As indicated, despite the footage, that shows the Hindenburg’s demise peoole still say ?explosion… It burnt very rapidly but it did not involve any “chemical explosion” ie any “significant over preasure event” but loss by physical bursting / tearing of the slightly preasurised hydrogen gas envelopes and subsequent under preasure causing the external skin to press in. Caused by a rapid intense internal fire that then spread to the flamable doped cotton envelope that became incandescent in the visable spectrum [1]…

The design of the Hindenburg like that of the Titanic was almost certainly central to it’s loss. If you look at it whilst the gas in the envelopes lacking an oxidizing agent would not have burnt or exploded once leaked out it would mix with air and be trapped inside the extetnal skin. In what mechanically would be a “chimney”. It’s only in the past few years that “chimney effect” in the spread and ferocity of fires has become a subject of actual scientific research (hence the redesign of fire escapes).

But it’s been well known that you get a blow toarch or rocket effect in certain types of in chimney combustion. You can demonstrate this yourself by making a simple “Rocket stove”. Without the chimney creating “the draw” the twigs etc in the burn box burn very inefficiently and slowly and most of the fuel is lost as smoke and similar highly flamable gassified “town” or “flu” gas. Add the chimney and not only does the fire in the burn box happen more efficiently, the flu gas burns in the chimney releasing nearly twice as much again energy and the roaring sound and flame jet that gives the stove type it’s name.

Turn the Hindenburg on it’s tail and see that the coaxial concentric design makes a chimney effect inevitable thus any small fire would get rapidly drawn through it (and there is a photo of burning gas jetting out of the nose to confirm this).

[1] Hydrogen produces very little visable light it’s spectrum being in the ultra violet. Hence the use of “mineral mantels” in “gas lamps” that are essentially a flax, cotton, or simillar net that has been heavily doped with a mineral that when heated creates the equivalent of “lime light”.

But this isn’t exactly true. North Koreans abroad aren’t “forced labor.” That would be too risky. They’d defect. They only let well-connected, politically reliable people outside the country, who often pay for the privilege since they’ll earn considerably more than they would at home:

The present author’s Russian-Korean contact from Sakhalin Island, an entrepreneur himself, recently complained about how corrupt the selection process has become in recent years. He said: “Nowadays, they send the sons of petty officials who have the right connections and can afford to pay bribes but have no clue how to lay bricks, paint walls or cut trees.”

You can find thanks to DuckDuck and a little Key-Foo their English language version via this link,

As for the story lots of sugar no meat.

There is nothing given that can be verified one way or the other.

Also from an intelligence point of view there is so much unexplained that giving anything said credence is difficult.

All that can be said is that Kiev like the US was clearly going to suffer from Germany’s unlawful under EU laws bring in of Nordstream. A point the US had made very vocally through out the project.

Others had pointed out that it also gave Putin near unrivaled control back over many EU and other Soverign Nations at the East of Europe. Especially as Putin had repeatedly in the past “used the gas tap” for political reasons.

Also it’s no secret that other “sabotage” stories involving German and Austrian located Petro-Chem sites have been put about as well.

I’m fairly certain Putin is going to be delighted about this story for the political knock on effects…

Which makes the “deniability” of “rougue operator” asspects distinctly curious, especially as the person it is about is being prosecuted for unrelated activities. Further curiosity is to be had from the claim he is a political opponent of the current Ukranian Government for not defending the Ukraine sufficiently whilst also claiming he is alined with the Pro Russia-Putin side of the fence…

Sadly as I indicated it’s all spun sugar with no meat to chew on.

A MSM article about Google’s replacement for GoogleG*** is a GoogleBodyCamera without a built in screen. Does pretty much what the GlassHole did but with an added cute little LED to let you know You Are On Candid Camera.

Of course, you can do nothing about what the wearer films or does with the film.

It is somewhat like gaming platforms now, and the 3d party programs like Discord and Twitch that let people not In-Game watch watch you (and others) playing and listen to commentary, the content of which you do not know, nor have any control over. Much of this content is uploaded into YouTube and other video storage systems with On Demand retrieval.

Having been in some of these external channels I can assure you, it is not PG13 and you might need an open urban dictionary for the latest in sexual, derogatory, political commentary that spews forth as fast as the speaker can spew it. (1) (2)

@Ferritecore – thank you for your input.
But what about difference of cost hydrogen versus helium?
I know Sergey Brin is not short of money but in prospective mix of gases may cause substantial savings plus no deficit of hydrogen.

vas pup November 12, 2023 5:35 PM

@Clive and @Ferritecore

More on the subject

“Use of hydrogen instead of helium

Helium was initially selected for the lifting gas because it was the safest to use in airships, as it is not flammable.[11] One proposed measure to save helium was to make double-gas cells for 14 of the 16 gas cells; an inner hydrogen cell would be protected by an outer cell filled with helium,[11][12] with vertical ducting to the dorsal area of the envelope to permit separate filling and venting of the inner hydrogen cells. At the time, however, helium was also relatively rare and extremely expensive as the gas was available in industrial quantities only from distillation plants at certain oil fields in the United States. Hydrogen, by comparison, could be cheaply produced by any industrialized nation and being lighter than helium also provided more lift. Because of its expense and rarity, American rigid airships using helium were forced to conserve the gas at all costs and this hampered their operation.[13]

The exact location of the initial fire, its source of ignition, and the source of fuel remain subjects of debate. The cause of the accident has never been determined conclusively, although many hypotheses have been proposed. Sabotage theories notwithstanding, one hypothesis often put forth involves a combination of gas leakage and atmospheric static conditions. Manually controlled and automatic valves for releasing hydrogen were located partway up one-meter diameter ventilation shafts that ran vertically through the airship.[69] Hydrogen released into a shaft, whether intentionally or because of a stuck valve, would have mixed with air already in the shaft — potentially in an explosive ratio. Alternatively, a gas cell could have been ruptured by the breaking of a structural tension wire causing a mixing of hydrogen with air.[70] The high static charge collected from flying within stormy conditions and inadequate grounding of the outer envelope to the frame could have ignited any resulting gas-air mixture at the top of the airship.[71] In support of the hypothesis that hydrogen was leaking from the aft portion of the Hindenburg prior to the conflagration, water ballast was released at the rear of the airship and six crew members were dispatched to the bow to keep the craft level.”

Clive Robinson November 12, 2023 10:54 PM

@ vas pup, Ferritecore, ALL,

Re : Helium v Hydrogen lift gases.

“Use of hydrogen instead of helium”

It’s actually complex and subject to current on-going research.

But… you need to remember that for oceanic cargo shipping ship design is such that it’s almost certainly going to stay more fuel efficient and produce less greenhouse gases in total than “Lighter Than Air”(LTA) transport ever will and for the same effective knots rating.

This means that LTA systems will be for restricted use in many respects.

One area that is supposadly “hush hush” is to act as a lift / elevator for solar powered gliders… The idea is not to disimilar to Virgin’s space flight system, which uses a plane to lift a rocket and give it initial velocity before dropping it. Put simply you use a hydrogen gas bag to lift a glider above the clouds and drop it into flight. Where solar film panels on the flight surfaces give enough energy to keep the glider in flight for weeks if not months at a time. These would then be used for what most “Low Earth Orbit”(LEO) satellites do but at a very small fraction of the cost and other issues[1]. China has recently proved much to the US Militaries embarrassment that you don’t even need the glider, just the gas bag and favourable winds.

Realistically this is where we will see the development of new lift gas LTA systems on what appears to be SciFi / “fringe thinking” applications, that have very real commercial advantage to current entrenched technologies.

The first consideration is the cost and limited availability of helium. It’s been said that,

“Hydrogen only requires water and a wire”

To obtain, which is a gross over simplification, and very inefficient. Worse much commercial hydrogen is obtained in ways that just move the huge carbon-footprint rather than reduce it (though this in theory alows carbon-recapture to be more viable…). Then there are the transportation issues of hydrogen which are still very much an on-going scientific and engineering technology race as the “other half” problem of using fuel cells for “Electric Vehicle”(EV) systems as current battery tech power density and charge times are still major EV stumbling blocks.

The dirty secret of Helium is “natural gas” and it’s massive carbon-footprint. Whilst Helium is the second most abundant element in the universe at ~25% and has about 80% of the neutrons in it, on Earth at best it’s a very very scarce non renuable natural resource we are going through at quite an alarming rate. What we have is the product of alpha radiation getting a full electron shell, which makes it effectively chemically inert so it quickly rises in our atmosphere and goes off into space as it gets stripped away by space weather. Thus our major source is where it’s trapped underground at the top of natural gas deposits… You don’t get the helium without the natural gas, and the natural gas is going to be burnt for energy production, hence the massive carbon footprint involved…

But helium is a real transportation issue, compressing it is realy not the route most want to go as it’s seen by some as a “bomb on wheels” issue. And cryo-liquification which gives much greater density, has it’s own issues as the tempratures involved are definately “snowflake in hell” survivability levels and that’s before the quaint issues of it’s superfluidity. After a couple of decades of Fullerene research we’ve not exactly moved to practical viability in that direction. So helium has quite an attendant carbon-footprint issue.

However which ever lift gas you use, a gas bag the size of a house will only give enough lift for a small child or family pet (~4stn / 25kg).

You can read up more on the lift-gas differences at,

But it assumes “control by venting” which whilst light weight is extreamly wastefull and drags those hidden carbon-footprints along like “a ball and shackle”.

[1] As some know 5G has gone into space but hit a few very recent road bumps due to “Chip-Wars”. The same technology but with much smaller antennas due to much less range are being looked at for being put into not just gliders but blimps. What is not much talked about is how much of the worlds militaries actually spend on doing “humanitarian” work and the issues and costs involved. That is environmental disasters are very much increasing due not just to changing weather issues but that populations are moving to land that was previously avoided for habitation. The use of altitude for communications is vital, using LTA systems which,

“Travel small and quick to deploy.”

Are seen by quite a few technologists as a low cost way forward and as such has entered “aerospace thinking” in not just the civilian but military sector. Getting a ballon to 300m with a lift capacity of 10kg is within “school science project” budget and gives a line of sight coverage of better than 100km diameter for a quite high bandwidth transponder that would be recoverable, reusable and maintainable.

@Just HOW do some people manage without brains?

Indeed, I do wonder

Re: Green Energy is bad

When the current coal, oil, and gas were laid down, some 300M years ago, the average temperature of the world was ~10 degrees Celsius higher (50 degrees Fahrenheit) than today. If we burn it all again, it looks like we will go back to that temperature again.

An increase of 50 degrees Fahrenheit means roughly, that those areas that are now 100F will be 150F, those areas that are occasionally 150F will go 160F. Do you know how many places with temperatures 150F and up are habitable?

Oh, and Greenland will become ice-free, adding some 6m (18 feet) to the see level. And a lot of the outer ice in Antarctica will melt off, adding another 3m or so. If you manage to use your brain, you might want to estimate how many people will have to move when that happens.

In short, either do something about the non-green energy or get ready to welcome a lot of climate refugees.[1]

[1] I understand that there are people who think they can solve that problem by shooting these refugees. I do not think that will actually work.

Re : Keys to the empire

From the Dan Godin ARS article,

“For the first time, researchers have demonstrated that a large portion of cryptographic keys used to protect data in computer-to-server SSH traffic are vulnerable to complete compromise when naturally occurring computational errors occur while the connection is being established.”

To points to note,

1, Left out the word “practical”.
2, “naturally occurring” errors.

If you look up “Q-codes” you will find “QRM” and “QRN” refering respectively to “Manmade” and “Natural” interferance in a communications channel. These Q-codes were developed by the British Admiralty back in 1909 and quickly became of “common use” by Morse-code CW operators and still are today.

Demonstrating that “communications” errors are to be expected and have been for over a century, thus are in no way unexpected events.

Similarly the British “Diplomatic Wireless Service”(DWS) that at one time ran the worlds largest high security “radio teletype”(RTTY) network used,

1, Message encryption
2, Super encryption
3, Link encryption

In part for security against human agents in acts of betrayal but also because encryption was known to be fragile and could for various reasons fail in some way. For instance the early “One Time Tape”(OTT) super encryption system whilst theoretically secure was found to have “natural faults” that we would now call a “side channel” that enabled the “Shannon : Perfect Secrecy” of the OTT to be stripped away (See history of the “BID Rockex” I’ve mentioned before).

Thus for way more than the Biblical “three score years and ten” not only have we known this class of failing was entirely possible, and happens but that we could implement preventative measures to limit or entirely stop the issue.

As I’ve pointed out AES used in “on-line” mode is not trustworthy, as it was riddled with “implementation side channels” which is why the NSA classified it as only suitable for Off-Line data at rest activities.

And why I’ve repeatedly said you need two “gapped” computers, one to do work on the second to do only communications. So anything you regarded as private or confidential would be done on the first computer and encrypted on it. This encrypted file would be taken across the gap to the second computer to be communicated. Thus even if there were exploitable side channels on the communications computer the actual data would be encrypted, even though communications meta-data and meta-meta-data was not.

The solutions to keeping meta and meta-meta data private / confidential are somewhat harder and require not immediately obvious mitigation solutions.

But in ICTsec we’ve had half a century to do things more confidentially and made the same known and avoidable mistakes over and over…

Who you might chose to blaim is an open question, but one thing is sure we’ve known things realy are “insecure” yet we chose to do nothing about it…

re: Libertarian (anarchist?)

Modern Libertarians have some ideas derived from the period of anarchists (1900s) but they do not have the same economic views.

In the 1900s, there was a strong movement to remove hereditary rulers and hereditary oligarchs. The idea that Kings are The Anointed of God was being challenged. These challenges have some application globally.

Modern Libertarians (USA) pull their economic views from the 1950s and the Chicago School of Economics promoting the ideas of Friedrich Hayek.

They are not anarchists in the old sense, but have little belief in governments of any type or system. It doesn’t matter what government or where. They do hide their anti-government beliefs behind the flags of ultra patriotism to promote the idea that

  • There is no need for The General Welfare of the Population

They are firmly in the camp of Bootstrap and Sink or Swim economics. They make no allocation or mitigation for circumstances beyond one’s personal control (Wars, Climate). It’s tough luck if a tornado or warhead lands on your house (they do seem to believe in luck).

What they firmly believe is that they are immune to such happenings and there should be zero interference in whatever economic endeavors they wish to undertake. There should be no public property and no restrictions on the uses for private property.

You can notice many countries have some of these policies and actively promote the ideas that there should be no aspects of The Public Good to impede their views.

A MSM report about the state of charity programs in the UK, is an example of their views. (1)

Charities in England are on the brink of insolvency after subsidising
heavily underfunded local authority and NHS contracts to the tune
of hundreds of millions of pounds donated to them by the public,
voluntary sector leaders have warned

The refusal of local authorities, the NHS and government
departments to fund the real cost of local service contracts – and
the built-in assumption that voluntary sector will deliver “on the
cheap” – was threatening the existence of vital local service

charities who feel their focus on the needs of
vulnerable beneficiaries is exploited by public bodies which
routinely expect charities not to charge for the full cost of the
service or to deliver it for “next to nothing”

“[The local authority] see contract payments
as ‘handouts to do-gooders’ instead of recognising that they are
paying us to work for them because we able to do it better, cheaper,
faster and with a more human and empathic approach.”

public sector “double standards” that accept private contractors must make a
profit while routinely expecting charities to run services at a loss,
with donors picking up the tab

That was my idea too, but this person claimed to be an Anarchist, IIRC, but was a staunch follower of Hayek and Libertarian Economics too. In this case it does not matter. Their climate opposition is totally based on their denial of all problems that cannot be solved by Free Market Fundamentalism.

They are firmly in the camp of Bootstrap and Sink or Swim economics.

“In this case, the flaw impacts the ‘is_user_admin’ function of the ‘WpFastestCacheCreateCache’ class within the WP Fastest Cache plugin, which is intended to check if a user is an administrator by extracting the ‘$username’ value from cookies.

!!! From cookies !!!

Makes the brain jolt with a “For real?” thought, and a secondary “Why would someone be that daft in this day and age?” triggering the is this just a journalist/editor mistake…

Then you read the next paragraph,

“Because the ‘$username’ input isn’t sanitized, an attacker may manipulate this cookie value to alter the SQL query executes by the plugin, leading to unauthorized access to the database.”

At which point you “face palm” yup it looks like it’s “a for realsy”…

And for those that doubt the face palm thought as the article goes on to state,

“[I]t should be noted that the vulnerability isn’t a complex one and hackers can figure out how to exploit it.”

Yup… This sort of mistake of not sanatising “user input” via what were then call “tokens” used in browser returns goes back to the early to mid 1990’s when “Middleware” first became a thing as user interfaces to backend databases and similar were migrated off of servers into user browsers, and the bad trend of “migrating left” to off load functionality out of backend business logic on the server and into the user browser became a trend…

I predicted it would go on for atleast half a decade and more from the Meltdown and Spectre attacks made public in Jan 2018[1]…

Well here we are a half decade later, and as predicted… But I did get one thing sort of wrong. I predicted it would be University and other academic researchers finding them in part to “make a name” and have in effect a “platinum plated C.V.” to boost their position in the very restricted jobs market.

But is Google security research realy different from academic research –other than the money/resources–?

In a way yes, but they are getting the job done faster in many ways and have more publicity potential, than most Universities have.

Any one want to “bet a beer bottle cap”[2] on the continuance over the next half decade?

Speaking of which, yes I think x86 has had it’s day and thus will be nolonger even a “second runner” in half a decade. Which is why I’ll keep my eye more on ARM and RISC-5 developments. Apple’s adventures with their CPU chips should be telling people that Intel are not just “behind the curve” but “took a wrong turn or five” and the “Current Idiot In Charge”(CIIC) is in no way giving confidence to shareholders or anyone else for that matter. So,

“Will Intel even still be here in a half decade?”

I suspect yes, but that will probably be more due to the simple fact they have so much to “Fire Sale” off than anything else.

[1] Whilst “only made public” in Jan 2018 the Meltdown and Spectre attacks were actually discovered well previously and Intel forced the information to be witheld from the public untill after,

Remember we’ve not realy kicked into “parallel computing” yet, because we are still trying to “beat the speed of light” rather than go other ways “outside the rack box”. And before we do that, we are already seeing hardware vulnerabilities showing with “LLM Booster” chips, and I suspect there is a whole world of hurt to go through there first. Because the way we are developing “Digital Neural Networks”(DNNs) currently is an “evolutionary cul-de-sac”, or for those of more canescent phraseology “an existential diverticulum” ending at best blindly, but will exhibit more as “scrapping the bottom of the barrel” than “bottom of the sack”.

Re : Looking from the light into the dark tetrad domains of the brain.

“It has been known that narcissists are willing to murder those who oppose them.”

Generally only when enranged. Because they are lacking in the,

1, (Socio)Psychopathic : Where there is no empathy inhibition.
2, Sadistic : Where pleasure is derived from watching or inflicting harm on others.
3, Machiavellian : To get others to inflict harm.
4, Spitfulnes : Where the desire to harm another is not inhibited by the usual self preservation harm avoidence (that is where the individual beleves they gain advantage or “status” by actively taking actions that will harm themselves on the assumption it will harm others more thus open the “status gap”).

Otherwise they will if in the public eye use others who are seen as “guard labour” or “Authoritarian followers”.

Which still even after C19 an under researched area, which is why looking back at the work of Bob Altemeyer who I’ve mentioned as a recommended read here and other places over the years is still rather more than just valid,

For another some would say professional view on Prof Altemeyer and similars work in part answers your question,

However I would recomend that all who can think and reason read it.

@ Bruce, ALL,

Re : Black out comming to get you all?

This “OMG we’re Doomed” story about US Power infrastructure has just been rekindled for the XXXth time this decade,

In part because we are aproaching Solar Maximum, in part because of political unrest and economic uncertainty.

And yes what it says is true the US Fed Gov reports with inputs from the likes of the CIA say that the power grid is “physically” in such a flaky state that should a suitable electromagnetic event happen the 66-90% of the US and North American population will have a high probability of being dead within a year…

Recentish news-worthy events in Texas and California have shown how quickly things can go bad. Less well known was NY State that should have got wiped of the planet, but by chance had started an upgrade program that “saved the bacon”.

However the articak should not make people panic, nor the luck of the New York incident complacent. What they should do is dig a little deeper and gain an understanding as to why the North Anerican power grid is so vulnerable.

Unfortunately two major reasons that will pop uo are,

1, It was designed to be a failure.
2, In more recent times lack of maintainance has made it worse.

The first is something kind of unique to the US in Western First World countries. Basically the infrastructure is done on the very cheap and a half century life time at best is what it’s designed for. With traditionaly design for fast maintainance making “the rot” due to the element’s much faster. The theory was that although it cost a lot more over the half century life, the initial costs would be low. Not quite “lop the branches off of a tree strap on a transformer and daisy chain some wire”, but many on seeing it will understand the sentiment.

The second problem is “pull the profit and run” thinking as part of the “don’t leave money on the table” neo-con mantra. As noted maintaining such a network is very expensive as it’s not designed to be resiliant or fault tolerant thus maintainance heavy with lots of emoloyees. BUT… if you stop the maintenance then the employment and materials costs disapear. But also failure issues do not immediately appear. So for a few years shareholder value looks great and the bonus as a C-suit accordingly high.

Then the rot bites, disasters strike, law suits spring up like mushrooms overnight, so the C-suits pull the “too critical to be alowed to fail” cord and protection from bankruptcy etc.

And you the consumer who has by various tricks of legislation and regulation discover you are paying more money for mains power per kW hour than the equivalent from batteries and gas guzzling generators…

But if it’s only for a few hours or a week then most will survive, so why the oft quoted 66 to 90% death rate? Well that’s for the mains power being gone for 6-24 months.

Why so long? Lets talk about transformers, they are all over the US grid and mostly unprotected against electromagnetic events, that are many many times worse with barely in spec overhead wires than with buried cables. Natural events due to solar weather such as CME’s and Charington events, cause the equivalent of massive DC currents to flow, and transformer windings over heat and melt or burn out rapidly. The problem, the US does not wind it’s own grid transformers, they come in from abroad, and whilst they are not quite “hand made” they are generally on a 12-24month order to delivery time, and they are very difficult to transport and install.

Now look around your home, what won’t work without power?

Well virtually everything. Heating, AC, cooking, freezer, computers, and communications. But after maybe a week water will stop flowing and sewage will back up with disease and death following to nearly every door… The higher the housing/population density in any given area the worse it will be.

But what about food? well it will become not just scarce but very expensive… Not that you will be able to buy it because “No power = No Job = No money = No food, health care, or roof over your head” (and social safety nets for the good of all are an anathema to way to many in the US).

We saw during the previous administration that you can forget about federal assistance and I think those in Texas and California know that state level assistance would be at best high velocity lead poisoning for the desperate.

But note I’ve only mentioned “natural electromagnetic events” that happen every 10-150 years depending on how you want to characterize them. I’ve not talked of EMP from nuclear or HERF devices, or cyber-security adverse events all of which tend to be more local than continental / worldwide, but certainly directed at critical nexi where possible.

For obvious reasons some people are getting twitchy about the “N-word” but in all honesty I still think the risk of that is about the same as normal which is low. In part because I conversly think the risk of cyber-security events are way way higher and rising. With the question of if they will become more of a defence rather than offence issue. Because ultimately cyber attacks only work for two reasons,

1, The attackers can reach them.
2, The attackers can take them over.

If people took a little thought into what they do, then their contingency planning would take “communications failure” into account and have a mittigation. Thus pulling the plug from the Internet should be possible. Which leaves the issue of a “dead hand payload” of an APT agent already in place waiting for a lack of “heart-beat”.

I won’t go into details but there are ways you can mitigate even “dead hand” APT if you plan sensibly in advance.

Things that have happened in the Ukraine with regards Cyber-Security should not have happened. In part it’s cost minimization, but also lets be honest as @JonKnowsNothing has pointed out today “crap-sodtware”. The lesson is none of our infrastructure systems should be in any way remotely connected to public networks, especially with the really crap awfull software in “embeded” and “appliance” devices for networking. The likes of Cisco should be ashamed of selling that sort of crapware junk.

The advantage of cyber-security adverse events from a defenders point of view is both the lack of, and difficulty of, “Physical Agency” that is going to cause major longterm damage. I won’t go into ICS, SCADA, and RTU systems but they are not the “bread and butter” of cyber attacks. Also with a little thought and planning secondary monitoring systems can be put in place.

For instance Stuxnet a decade ago did damage because there were no secondary monitoring systems in place, so the repeated run-up / run-down by the centrifuge controlers necessary to cause the damage went unnoticed…

Anyone these days with any sense and high value systems to run, would you have hoped, taken that on board and put the required secondary systems in place.

However recent events by certain states presumably under “shareholder originated preasure” suggests very strongly that certain infrastructure managment realy are lacking in the sense department… However the court cases are double edged, they now will find it extreamly difficult to claim they were “not negligent” if things do go pear-shaped.

Over all that means that the 66-90% US fatality rate is now likely to be actually somewhat lower than it was a decade or more ago when first indicated.

But one word of advice, don’t go out and by a generator. Firstly because very very few know how to “wire them in” safely, not just for the home occupants but their neighbours and for the power company employees as well.

Also some generators run on “petrochem fuels” one result of which is significant carbon monoxide and other very life shortening emmissions, they are also not just a fire risk, but because they are noisy and left mostly unatended a theft risk with the attendent risk of violence.

However there are known ways to connect “Solar Generators” into the equivalent of UPSs very safely and these will keep small fridges running for meds and the like, and for “knowledge workers” a reasonable chance to keep your job going especially if you use satellite rather than mobile or land line communications, but… it also needs your employer to be suitably set up, which is probably unlikely.

But natural electromagnetic events like CME’s and Carrington Events are quite survivable, as humans have happily lived through them before any number of times. But the world was barely electrically sophisticated 164 years ago, back in 1859 when the telegraph was still magically impresive, though it only ran on batteries and the only power coming into homes was biological on two or for legs or coal gas for lighting, and in factories steam driven shafts. It was a decade or so later that electric arc lamps were to appear with a harshness few found appealing. So the impact was more awe than life altering,

Not so today, we are slave to the movment of charge in so many ways that few realise even when they go camping, what it’s loss actually would mean.

But I actually doubt it would be even close to existential for mankind as much of the world still does not depend on electricity.

As for the West, again many parts are not as dependent on electricity as we are in high population density places like London, New York, Paris or Brussels…
