  • If that were the case then they would have written that into their constitution 70 years ago. And they wouldn’t have assasinated their own prime minister 30 years ago.

    Heck, the current minister of national security Ben-Gvir was rejecting from mandatory constriction by the IDF, and convicted in an Israeli court of supporting (Jewish) terrorism after being indicted by an Israeli prosecutor.

    These are not things that happen in a country that is unified in its goals.


  • The Israeli government has no idea what it is doing. Literally. The current government was a barely held together coalition prior to October 7. In the direct aftermath, they formed a unity government and war cabinet that collapsed last week.

    Their prime minister has been indicated on corruption and bribertmy charges, which are currently on hold for obvious reasons. By most indications his primary motivation in this matter is to stay in power himself, with Israel’s national interests being secondary.

    Individual members of IDF leadership have called Israel’s stated objectives “unachievable”.

    Israel simultaneously wants to live in peace as a liberal Jewish state without commiting any form of ethnic clensing; and achieve its manifest destiny of establishing a Jewish theocracy across Judea and Samaria.

    These are deep questions that get to the core of what Israel is and stands for. Questions that are to be answered by the Israeli constitution in the 50s. That never happened because Israel was never able to agree on a constitution [0].

    Right now, Israel is just reacting, without any long term strategic vision. Various factions are trying to use that chaos to advance their own long term vision.

    [0] Which led to the big judicial reform constitutional crisis that was a giant political crisis before October.


  • Because the thing people refer to when they say “linux” is not actually an operating system. It is a family of operating systems built by different groups that are built mostly the same way from mostly the same components (which, themselves are built by separate groups).


  • Sudo is a setuid binary, which means it executes with root permissions as a child of of the calling process. This technically works, but gives the untrusted process a lot of ways to mess with sudo and potentially exploit it for unauthorized access.

    Run0 works by having a system service always running in the background as root. Running a command just sends a message to the already running seevice. This leaves a lot less room for exploits.



  • I’m one of those security specialists (although not on mastodon). To be clear, if a vulnerable version of libxz were included in a distribution that we actually use; this would be an all hands on deck, drop everything until it is fixed emergency.

    Having said that, for an average user, it probably doesn’t matter. First, many users just don’t have the vulnerable version installed. All things considered, it was found very quickly; so only rolling release distros would have it. Additionally, it appears that only .deb or .rpm based distributions would have it. Not because they are particularly vulnerable, the attack explicitly tests for it.

    However, lets set all of this asside and assume a typical use is running a vulnerable system. In my assessment, the risk to them is still quite low. With most vulnerabilities, the hard part is discovering it. Once that happens, the barrier to exploiting it is relatively low, so you get a bunch of unrelated hackers trying to exploit any system they can find. This case is different; exploiting it requires the attackers private key. Even though the attack is now widely known, there is still only 1 organization capable of using it.

    Further, this attack was sophisticated. I’m not going to go as far as others in saying that only a state actor could do it. However, it is hard to think of anyone other than a state actor who would do it. Maybe a group of college kids doing it for the lolz research? But, if the motivation us lolz, I don’t see them pivoting to do anything damaging with it. And even if they wanted to, there would still only be a handful of them. In short, this is one of those cases where obscurity works. Whoever did this attack does not know or care about Joe the Linux user; and they were probably never going to risk burning it by exploiting it on a large scale.

    However, setting all of that asside, suppose you were using vulnerable software, and someone with the private key is interested in your home system. First, you would need to be running OpenSSH on a remotely accessible interface. [0]. Second, you would need your firewall to allow remote SSH traffic. Third, you would need your router to have port forwarding enabled; and explicitly configured to forward traffic to your OpenSSH server [1].

    If all of that happens; then yes, you would be at risk.

    [0] Even though the attack itself is in the libxz library, it appears to specifically target OpenSSH.

    [1] Or, the attacker would need some other mechanism to get on the same network as you.




  • I’d just like to interject for a moment. What you’re referring to as Linux, is in fact, GNU/Linux, or as I’ve recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX.

    Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called “Linux”, and many of its users are not aware that it is basically the GNU system, developed by the GNU Project.

    There really is a Linux, and these people are using it, but it is just a part of the system they use. Linux is the kernel: the program in the system that allocates the machine’s resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called “Linux” distributions are really distributions of GNU/Linux.






  • There are still a lot of rather arbitrary decisions to make.

    Is 4/pi inside or outside of the summation?

    Is it (-1)^n+1 or (-1)^n with an additional negative sign in any of the other natural locations for it.

    Is the e term outside of the fraction with a negative exponent, or part of the denominator.

    Do you start with n=0 or n=1 (and adjust the terms inside the summation accordingly)

    Did they expand (2n+1)^2?


  • As a kid I attended a Jewish day school, and we had a year long class on European-Jewish history through the Holocaust.

    The post screenshotted (allegedly from the AGA) reads almost like it came right out of that era as a piece of anti-semetic propoganda.

    Seriously. Weather the post was actually from the AGA, or an anti-semetic propogandist, it is 100% blood libel, and should treated as such.



  • Coming around? When was he on the wrong side of this issue?

    His October 10 statement includes:

    Right now, the international community must focus on reducing humanitarian suffering and protecting innocent people on both sides of this conflict. The targeting of civilians is a war crime, no matter who does it. Israel’s blanket denial of food, water, and other necessities to Gaza is a serious violation of international law and will do nothing but harm innocent civilians. The United States has rightly offered solidarity and support to Israel in responding to Hamas’ attack. But we must also insist on restraint from Israeli forces attacking Gaza and work to secure UN humanitarian access. Let us not forget that half of the two million people in Gaza are children. Children and innocent people do not deserve to be punished for the acts of Hamas.

    October 10. 3 days after the initial attack.

    Back in January he tried conditioning aid to Israel and requiring the state department to issue human rights report on their conducts.
