De Nederlandse metromythe

OV Magazine

Mensen in grote steden verlaten massaal het ov, ziet bouwkundig ingenieur Wolfgang Spier op basis van rapporten van het CBS, CROW en KiM. En dat komt door investeringen in metro, wat ov-netwerken uitdunt en autoverkeer promoot. Hij pleit voor een anders mobiliteitsbeleid en daagt vervoerkundigen uit zijn visie te weerleggen.

Om voldoende passagiers in langere metrovoertuigen te krijgen worden namelijk talloze ‘gewone’ tram- en buslijnen opgeheven. De meeste ov-reizigers moeten dan verder lopen naar minder haltes en bussen rijden niet meer rechtstreeks van platteland of buitenwijk naar stadscentrum, maar naar een metrostation, waar ze moeten overstappen.

Omdat reizigers daar moeten uitchecken en voor een tweede keer moeten inchecken en het aantal incheckers wordt geteld, telt iedere overstapper als twee instappers. Zo verschijnen indrukwekkende groeicijfers: méér afgelegde ov-kilometers, méér instappers en méér inkomsten. In werkelijkheid daalt het stedelijk ov-gebruik. (...)

Zelfs voor de meerderheid van alle Amsterdammers veroorzaakt de metrolijn langere ov-reistijden, berekende de NRC in 2018. Volgens diezelfde krant heeft Utrecht ’s werelds duurste sneltramlijn, de Uithoflijn. Daarvoor verdwenen tien Uithof-buslijnen. (...)

Omdat Nederlanders ov véél minder gebruiken dan fietsen zijn langere sneltrams/metro’s niet nodig. Toch willen Nederlandse steden ook deze prestigieuze voertuigen. Daarom dunnen ze als enige ter wereld ov-netwerken uit.

Ze voorspellen dat ov-gebruik fors toeneemt, waardoor bussen te klein worden. Volgens de snelstgroeiende stad, Utrecht, zou ov-gebruik bijvoorbeeld na 1991 in opeenvolgende decennia met 160 procent toenemen. Politici stemden daarom vóór die Uithoflijn. In 2019 gingen echter nog maar 4 van de 100 verplaatsingen per stedelijk ov (versus 12 procent in 1991). (...)

Prognoses komen echter prominent in het nieuws. CBS-tellingen achteraf niet. Die tonen de werkelijkheid. Wetenschappers schreven letterlijk in hun rapport ‘Geschiedenis van de toekomst’ dat ‘politici met prognoses op het verkeerde been worden gezet’. (...)

Voorlopig blijven ov-reizigers afhaken. Daarom komen de grote steden inmiddels tientallen miljoenen ov-inkomsten tekort. Ze moeten nóg meer buslijnen opheffen, waardoor nóg meer ov-reizigers afhaken en ov-inkomsten verder dalen. (...)

Als spoorlijnen viersporig worden kunnen ze evenveel mensen vervoeren als twintigbaanswegen. Nederlandse enige langere viersporige traject is Houten – Hoofddorp. Tussen Amsterdam en Hoofddorp wil men twee metrosporen aanleggen, parallel met deze vier treinsporen. Dat worden dus zes sporen, terwijl spoorlijnen tussen grote steden als Rotterdam – Utrecht, Den Haag – Utrecht, Breda – Tilburg, en-nog-veel-meer, tweesporig blijven.

Ook is men zuinig met treinperrons, zoals in Utrecht. (...)

De werkwijze is intussen niet verbeterd. Afgelopen augustus bleek bijvoorbeeld het in aanbouw zijnde hoofdstation Groningen te weinig perroncapaciteit te krijgen. Eerder werd bekend dat Amsterdam CS te weinig perroncapaciteit krijgt, waardoor intercity’s Amersfoort-Amsterdam CS moeten verdwijnen.

Volgens eigen zeggen streeft het ministerie met onderstaande visie naar beter ov en minder files. Het tegenovergestelde is nodig om dat echt te realiseren. (...)

FBI must be abolished – former US presidential candidate

https://invidious.namazso.eu/watch?v=QhcCDGW4SSo
http://ronpaulinstitute.org/archives/featured-articles/2022/december/19/twitter-files-make-it-clear-we-must-abolish-the-fbi/

The agency used its influence at #Twitter to #unconstitutionally crush #free-speech, retired congressman #RonPaul argues

The #FBI used proprietary backchannels at Twitter to infringe on Americans’ #FirstAmendment rights and should be “ #abolished,” former #US Republican presidential candidate Ron Paul stated on Monday.

While Twitter has previously skirted accusations of violating Americans’ right to free speech by arguing it is a private corporation, Paul pointed out that recently released internal communications between employees of the social media giant and #government officials in the FBI and other agencies confirm the platform was acting as a surrogate of the state.

“Now we have proof that the FBI (along with US intelligence agencies and the Department of Homeland Security) have been acting through ‘private’ social media companies to manipulate what Americans are allowed to say when they #communicate with each other,” the former Texas congressman wrote in his weekly column for his website, the Ron Paul Institute for Peace and Prosperity.

“We do not need the FBI and #CIA and other federal agencies viewing us as the enemy and attacking our #Constitution. #End-the-Fed…and end the #Federal-Bureau-of-Investigation!” Paul concluded, referencing his long-standing call to liquidate the US’ privately-held central bank.

FBI agents emailed Twitter Trust and Safety chief #YoelRoth about 150 times between 2020 and 2022, according to internal communications released by platform CEO #ElonMusk earlier this month, with most messages involving requests for #censorship. However, even as Musk was releasing the Twitter documents, former FBI general counsel turned Twitter lawyer #JimBaker was ‘vetting’ the messages, allegedly without Musk’s knowledge. When this was brought to the billionaire’s attention, Baker was dismissed – but not before he had reshaped the narrative.

Twitter has reportedly hired dozens of FBI agents and other intelligence and military veterans in recent years, raising questions about the platform’s impartiality even before a lawsuit filed by the Missouri and Louisiana attorneys general revealed earlier this year that employees were regularly meeting with representatives of US government agencies to coordinate the #banning and #suppression of certain accounts and narratives.

While Paul questioned the media’s failure to make the #TwitterFiles the scandal that he felt they deserved, he was encouraged by a recent survey showing 70% of Americans believe Congress must take action to end #collusion between #BigTech and #BigBrother.

The FBI said in a statement released following the publication of the Twitter Files that the agency “regularly engages with private sector entities to provide information specific to identified foreign malign influence actors’ subversive, undeclared, covert or criminal activities.” It added that “private sector entities independently make decisions about what, if any, action they take on their platforms and for their customers after the FBI has notified them.”

Understanding The Linux File Permissions

Bild/Foto
Quite a good summary overview, in the linked article below, which is easy to follow. As the saying goes for Linux “Everything in Linux is a file”, so understanding file permissions is quite important. Also, if you do any web hosting or similar server based applications, it is often incorrect file permissions that create errors (usually just needing file ownership or permissions corrected to solve them).

I can probably add, too, that you can also change file permissions and ownership across all files and sub-directories within a folder, with the addition of the -R option. Although there are many flavours of Linux distros out there, these basics remain the same across all of them.

I think I already asked, it's an old problem I drag:

Say I have a bunch of files stored in an arborescence (they are HDF5 but the format is not the most important here), they are coming from a monitoring system which spits data + metadata regularly.

I want to be able to search for files based on metadata. And I kind of hate DB like SQL and stuff.

I was thinking using a basic method : get all the metadata from all files and put them in a single central reference file.
For that I could use pytables, which would itself produce a hdf5 with all metadata, and with a possibility of searching in that file (since pytables support something that looks like DB request)
I'm not really fond of that solution because it relies quite heavily on python, and python is not stable IMO, but it seems like a compromise.

Any thought on this ? I may miss some very basic stuff, like "stop hating DB" for example.
Of course I would also be interested by any existing piece of software that is able to manage a bunch of files based on metadata (didn't find something "at my level" yet)

Kids who grew up with search engines could change STEM education forever - The Verge

Gradually, Garland came to the same realization that many of her fellow educators have reached in the past four years: the concept of file folders and directories, essential to previous generations’ understanding of computers, is gibberish to many modern students.

Glenn Greenwald: Why privacy matters

https://www.youtube.com/watch?v=pcSlowAhvUk

#GlennGreenwald was one of the first #reporters to see — and #write about — the #EdwardSnowden #files, with their #revelations about the #UnitedStates' extensive #surveillance of #private #citizens. In this searing #talk, Greenwald makes the case for why you need to care about #privacy, even if you’re “not doing anything you need to hide."
