Charlie Kirk Was Not Practicing Politics the Right Way
Thursday morning, Ezra Klein at the New York Times published a column titled “Charlie Kirk Was Practicing Politics the Right Way.” Klein’s general thesis is that Kirk was willing to talk to anyone, regardless of their beliefs, as evidenced by what he was doing while he was shot, which was debating people on college campuses. Klein is not alone in this take; the overwhelming sentiment from America’s largest media institutions in the immediate aftermath of his death has been to paint Kirk as a mainstream political commentator, someone whose politics liberals and leftists may not agree with but someone who was open to dialogue and who espoused the virtues of free speech.“You can dislike much of what Kirk believed and the following statement is still true: Kirk was practicing politics in exactly the right way. He was showing up to campuses and talking with anyone who would talk to him,” Klein wrote. “He was one of the era’s most effective practitioners of persuasion. When the left thought its hold on the hearts and minds of college students was nearly absolute, Kirk showed up again and again to break it.”
“I envied what he built. A taste for disagreement is a virtue in a democracy. Liberalism could use more of his moxie and fearlessness,” Klein continued.
Kirk is being posthumously celebrated by much of the mainstream press as a noble sparring partner for center-left politicians and pundits. Meanwhile, the very real, very negative, and sometimes violent impacts of his rhetoric and his political projects are being glossed over or ignored entirely. In the New York Times, Kirk was an “energetic” voice who was “critical of gay and transgender rights,” but few of the national pundits have encouraged people to actually go read what Kirk tweeted or listen to what he said on his podcast to millions and millions of people. “Whatever you think of Kirk (I had many disagreements with him, and he with me), when he died he was doing exactly what we ask people to do on campus: Show up. Debate. Talk. Engage peacefully, even when emotions run high,” David French wrote in the Times. “In fact, that’s how he made his name, in debate after debate on campus after campus.”
This does not mean Kirk deserved to die or that political violence is ever justified. What happened to Kirk is horrifying, and we fear deeply for whatever will happen next. But it is undeniable that Kirk was not just a part of the extremely tense, very dangerous national dialogue, he was an accelerationist force whose work to dehumanize LGBTQ+ people and threaten the free speech of professors, teachers, and school board members around the country has directly put the livelihoods and physical safety of many people in danger. We do no one any favors by ignoring this, even in the immediate aftermath of an assassination like this.
Kirk claimed that his Turning Point USA sent “80+ buses full of patriots” to the January 6 insurrection. Turning Point USA has also run a “Professor Watchlist,” “School Board Watchlist,” and “Campus Reform” for nearly a decade.
“America’s radical education system has taken a devastating toll on our children,” Kirk said in an intro video posted on these projects’ websites. “From sexualized material in textbooks to teaching CRT and implementing the 1619 Project doctrine, the radical leftist agenda will not stop … The School Board Watch List exposes school districts that host drag queen story hour, teach courses on transgenderism, and implement unsafe gender neutral bathroom policies. The Professor Watch List uncovers the most radical left-wing professors from universities that are known to suppress conservative voices and advance the progressive agenda.”
These websites have been directly tied to harassment and threats against professors and school board members all over the country. Professor Watchlist lists hundreds of professors around the country, many of them Black or trans, and their perceived radical agendas, which include things like supporting gun control, “socialism,” “Antifa,” “abortion,” and acknowledging that trans people exist and racism exists. Trans professors are misgendered on the website, and numerous people who have been listed on it have publicly spoken about receiving death threats and being harassed after being listed on the site.
One professor on the watchlist who 404 Media is granting anonymity for his safety said once he was added to the list, he started receiving anonymous letters in his campus mailbox. “‘You're everything wrong with colleges,’ ‘watch your step, we're watching you’ kind of stuff,” he said, “One anonymous DM on Twitter had a picture of my house and driveway, which was chilling.” His president and provost also received emails attempting to discredit him with “all the allegedly communist and subversive stuff I was up to,” he said. “It was all certainly concerning, but compared to colleagues who are people of color and/or women, I feel like the volume was smaller for me. But it was certainly not a great feeling to experience that stuff. That watchlist fucked up careers and ruined lives.”
The American Association of University Professors said in an open letter in 2017 that Professor Watchlist “lists names of professors with their institutional affiliations and photographs, thereby making it easy for would-be stalkers and cyberbullies to target them. Individual faculty members who have been included on such lists or singled out elsewhere have been subject to threats of physical violence, including sexual assault, through hundreds of e-mails, calls, and social media postings. Such threatening messages are likely to stifle the free expression of the targeted faculty member; further, the publicity that such cases attract can cause others to self-censor so as to avoid being subjected to similar treatment.” Campus free speech rights group FIRE found that censorship and punishment of professors skyrocketed between 2020 and 2023, in part because of efforts from Professor Watchlist.
Many more professors who Turning Point USA added to their watchlist have spoken out in the past about how being targeted upended their lives, brought years of harassment down on them and their colleagues, and resulted in death threats against them and their loved ones.
At Arizona State University, a professor on the watchlist was assaulted by two people from Turning Point USA in 2023.
“Earlier this year, I wrote to Turning Point USA to request that it remove ASU professors from its Professor Watchlist. I did not receive a response,” university president Michael Crow wrote in a statement. “Instead, the incident we’ve all now witnessed on the video shows Turning Point’s refusal to stop dangerous practices that result in both physical and mental harm to ASU faculty members, which they then apparently exploit for fundraising, social media clicks and financial gain.” Crow said the Professor Watchlist resulted in “antisemitic, anti-LGBTQ+ and misogynistic attacks on ASU faculty with whom Turning Point USA and its followers disagree,” and called the organization’s tactics “anti-democratic, anti-free speech and completely contrary” to the spirit of scholarship.
Kirk’s death is a horrifying moment in our current American nightmare. Kirk’s actions and rhetoric do not justify what happened to him because they cannot be justified. But Kirk was not merely someone who showed up to college campuses and listened. It should not be controversial to plainly state some of the impact of his work.

Dragon is the Latest, and Final, Craft to Reboost ISS
The International Space Station has been in orbit around the Earth, at least in some form, since November of 1998 — but not without help. In the vacuum of space, an object in orbit can generally be counted on to remain zipping around more or less forever, but the Station is low enough to experience a bit of atmospheric drag. It isn’t much, but it saps enough velocity from the Station that without regular “reboosts” to speed it back up , the orbiting complex would eventually come crashing down.
Naturally, the United States and Russia were aware of this when they set out to assemble the Station. That’s why early core modules such as Zarya and Zvezda came equipped with thrusters that could be used to not only rotate the complex about all axes, but accelerate it to counteract the impact of drag. Eventually the thrusters on Zarya were disabled, and its propellant tanks were plumbed into Zvezda’s fuel system to provide additional capacity.
Visiting spacecraft attached to the Russian side of the ISS can transfer propellant into these combined tanks, and they’ve been topped off regularly over the years. In fact, the NASA paper A Review of In-Space Propellant Transfer Capabilities and Challenges for Missions Involving Propellant Resupply, notes this as one of the most significant examples of practical propellant transfer between orbital vehicles, with more than 40,000 kgs of propellants pumped into the ISS as of 2019.
But while the thrusters on Zvezda are still available for use, it turns out there’s an easier way to accelerate the Station; visiting spacecraft can literally push the orbital complex with their own maneuvering thrusters. Of course this is somewhat easier said than done, and not all vehicles have been able to accomplish the feat, but over the decades several craft have taken on the burden of lifting the ISS into a higher orbit.
Earlier this month, a specially modified SpaceX Cargo Dragon became the newest addition to the list of spacecraft that can perform a reboost. The craft will boost the Station several times over the rest of the year, which will provide valuable data for when it comes time to reverse the process and de-orbit the ISS in the future.
Reboosting the Russian Way
By far the easiest way for a visiting spacecraft to reboost the ISS is to dock with the rear of the Zvezda module. This not only places the docked spacecraft at what would be considered the “rear” of the Station given its normal flight orientation, but puts the craft as close as possible to the Station’s own thrusters. This makes it relatively easy to compute the necessary parameters for the thruster burn.
Historically, reboosts from this position have been performed by the Russian Progress spacecraft. Introduced in 1978, Progress is essentially an uncrewed version of the Soyuz spacecraft, and like most of Russia’s space hardware, has received various upgrades and changes over the decades. Progress vehicles are designed specifically for serving long-duration space stations, and were used to bring food, water, propellants, and cargo to the Salyut and Mir stations long before the ISS was even on the drawing board.
Reboosts could also be performed by the Automated Transfer Vehicle (ATV). Built by the European Space Agency (ESA), the ATV was essentially the European counterpart to Progress, and flew similar resupply missions. The ATV had considerably greater cargo capacity, with the ability to bring approximately 7,500 kg of materials to the ISS compared to 2,400 kg for Progress.
Only five ATVs were flown, from 2008 to 2014. There were several proposals to build more ATVs, including modified versions that could potentially even carry crew. None of these versions ever materialized, although it should be noted that the design of the Orion spacecraft’s Service Module is based on the ATV.
American Muscle
Reboosting the ISS from the American side of the Station is possible, but involves a bit more work. For one thing, the entire Station needs to flip over, as the complex’s normal orientation would have the American docking ports facing fowards. Of course, there’s really no such thing as up or down in space, so this maneuver doesn’t impact the astronauts’ work. There are however various experiments and devices aboard the Station that are designed to point down towards Earth, so this reorientation can still be disruptive.
As described in the “AUTO REBOOST” section of the STS-129 Orbit Operations Checklist, the Shuttle’s computer would actually be given control of the maneuvering systems of the ISS so the entire linked structure can be rotated into the correct position. A diagram in the Checklist even shows the approximate angle the vehicle’s should be at for the Shuttle’s maneuvering thrusters to line up properly.
With the retirement of the Space Shuttle in 2011, maintaining the Station’s orbit became the sole domain of the Russians until 2018, when the Cygnus became the first commercial spacecraft to perform a reboost. The cargo spacecraft had a swiveling engine which helped get the direction of thrust aligned, but the Station did still need to rotate to get into the proper position.
After performing a second reboost in 2022, the Cygnus spacecraft was retired. It’s replacement, the upgraded Cygnus XL — is currently scheduled to launch its first mission to the ISS no earlier than September 14th.
Preparing for the Final Push
That brings us to the present day, and the Cargo Dragon. SpaceX had never designed the spacecraft to perform a reboost, and indeed, it would at first seem uniquely unsuited for the task as its “Draco” maneuvering thrusters are actually located on the front and sides of the capsule. When docked, the primary thrusters used for raising and lowering the Dragon’s own orbit are essentially pressed up against the structure of the ISS, and obviously can’t be activated.
To make reboosting with the Dragon possible, SpaceX added additional propellant tanks and a pair of rear-firing Draco thrusters within the spacecraft’s un-pressurized “trunk” module. This hollow structure is usually empty, but occasionally will hold large or bulky cargo that can’t fit inside the spacecraft itself. It’s also occasionally been used to deliver components destined to be mounted to the outside of the ISS, such as the for the outside of the ISS, such as the International Docking Adapter (IDA) and the roll-out solar panels.
While the ability to have the Dragon raise the orbit of the International Space Station obviously has value to NASA, the implications of this experiment go a bit farther.
SpaceX has already been awarded the contract to develop and operate the “Deorbit Vehicle” which will ultimately be used to slow down the ISS and put it on a targeted reentry trajectory sometime after 2030. Now that the company has demonstrated the ability to add additional thrusters and propellant to a standard Dragon spacecraft via a module installed in the trunk, it’s likely that the Deorbit Vehicle will take a similar form.
So while the development of this new capability is exciting from an operational standpoint, especially given deteriorating relations with Russia, it’s also a reminder that the orbiting laboratory is entering its final days.
4-bit Single Board Computer Based on the Intel 4004 Microprocessor
[Scott Baker] is at it again and this time he has built a 4-bit single board computer based on the Intel 4004 microprocessor.
In the board design [Scott] covers the CPU (both the Intel 4004 and 4040 are supported), and its support chips: the 4201A clock-generator, its crystal, and the 4289 Standard Memory Interface. The 4289 irons out the 4-bit interface for use with 8-bit ROMs. Included is a ATF22V10 PLD for miscellaneous logic, a 74HCT138 for chip-select, and a bunch of inverters for TTL compatibility (the 4004 itself uses 15 V logic with +5 V Vss and -10 V Vdd).
[Scott] goes on to discuss the power supply, ROM and page mapper, the serial interface, the RC2014 bus interface, RAM, and the multimodule interface. Then comes the implementation, a very tidy custom PCB populated with a bunch of integrated circuits, some passive components, a handful of LEDs, and a few I/O ports. [Scott] credits Jim Loo’s Intel 4004 SBC project as the genesis of his own build.

Arriva SpamGPT! il nuovo kit di phishing che combina AI, Spam e Genialità diabolica
Un nuovo strumento chiamato SpamGPT è apparso sui forum underground ed è rapidamente diventato oggetto di discussione nel campo della sicurezza informatica. Il software malevolo combina le capacità dell’intelligenza artificiale generativa con un sistema completo per l’invio di email di massa e si propone come una soluzione pronta all’uso per condurre campagne di phishing.
I suoi sviluppatori chiamano apertamente il prodotto “spam-as-a-service“, sottolineando che combina tutte le funzioni di una piattaforma di marketing professionale, ma viene utilizzato per attività illegali.
L’interfaccia di SpamGPT riproduce fedelmente i servizi di email marketing legali: sono disponibili moduli per la gestione delle campagne, le impostazioni SMTP e IMAP, i controlli di recapito e le analisi. Il pannello di controllo scuro è accompagnato da un assistente KaliGPT integrato che genera il testo delle email, seleziona gli argomenti e fornisce persino consigli su come aumentare il coinvolgimento delle vittime. Il controllo automatico della consegna dei messaggi è implementato tramite il monitoraggio in tempo reale della casella di posta, che consente agli operatori di verificare immediatamente se una lettera è arrivata nella posta in arrivo o è stata filtrata.
I creatori affermano che la piattaforma è ottimizzata per bypassare i filtri di Gmail, Outlook, Yahoo e Microsoft 365 e utilizza anche servizi cloud come AWS e SendGrid per mascherare il traffico dannoso come legittimo. L’attenzione non è rivolta solo alla scalabilità, ma anche alla consegna garantita: lo strumento non si limita a inviare email, ma si assicura che arrivino nelle cartelle principali dei destinatari.
Il kit include un “Corso di Mastery sull’Hacking SMTP” che spiega come ottenere e generare server per la distribuzione. Agli utenti viene mostrato come prendere il controllo di host di posta elettronica scarsamente protetti o mal configurati, nonché come creare un numero illimitato di account SMTP. Il pannello di controllo supporta l’importazione in blocco di server, la verifica della loro funzionalità e il bilanciamento del carico su decine di fonti, rendendo gli attacchi sostenibili e su larga scala.
Una parte importante del kit sono gli strumenti per la sostituzione dei mittenti e la creazione di intestazioni personalizzate. Ciò consente agli aggressori di imitare domini e marchi attendibili, aggirando i meccanismi di protezione di base. Le campagne stesse vengono create tramite un sistema che ricorda un CRM: gli aggressori possono impostare modelli, pianificare gli invii, cambiare server e monitorare statistiche dettagliate su aperture e clic.
In sostanza, SpamGPT ha trasformato un processo complesso in un kit di costruzione che anche i criminali informatici meno esperti possono realizzare. Tutto ciò che prima richiedeva un team di programmatori ora viene svolto tramite un’interfaccia intuitiva da un singolo operatore che paga circa 5.000 dollari. Questo riduce drasticamente la barriera d’ingresso e rende gli attacchi di phishing di massa ancora più accessibili.
Gli esperti avvertono che per contrastare tali soluzioni, le aziende devono rafforzare la protezione dei domini di posta. È necessario configurare DMARC, SPF e DKIM , nonché implementare moderni sistemi anti-phishing basati sul machine learning, in grado di identificare segnali di testo generativo e modelli di mailing atipici.
Solo una combinazione di tecnologie, scambio di informazioni e monitoraggio collettivo ci permetterà di anticipare gli aggressori che utilizzano l’intelligenza artificiale per automatizzare gli attacchi.
