[sneak peak] Upcoming @TimescaleDB 2.19 release significantly improves write I/O spikes while refreshing its continuous aggregates (incremental materialized views).

Particularly useful whenever:

- Creating new caggs on top of historical raw data, or

- Supporting late-arriving data, which necessitates recomputing dependent aggregations (which Timescale handles seamlessly).

Notice the before (left) vs. after (right)? 🔥

Ausländisches Kapital unterstützt die Propaganda einer Partei, die in Deutschland die Demokratie zerstören will. Diese offene Form der Wahleinmischung ist ein Einschnitt.

It will also be extremely important to analyze the strengths and limitations of the new system. Here are some examples of tasks that o3 couldn't solve on high-compute settings (even as it was generating millions of CoT search tokens and consuming thousands of dollars of compute in the process).

Interestingly this first task was the one we had in our university tour presentation to illustrate "it's easy for humans, hard for AI"

Goodbye, Foreign Minister @DmytroKuleba. You were not the worst one, but as a Ukrainian living in 🇩🇪 for more than 11 years I won’t miss your populism and your disdain towards Ukrainians abroad.

[Dmytro Kuleba @DmytroKuleba]

Protecting the rights and interests of Ukrainian citizens abroad has always been and remains a priority for the MFA. At the same time, under the circumstances of Russia’s full-scale aggression, the main priority is to protect our Homeland from destruction.

How it looks like now: a man of conscription age went abroad, showed his state that he does not care about its survival, and then comes and wants to receive services from this state. It does not work this way. Our country is at war.

Besides, the obligation to update one's documents with the conscription centers existed even before the new law on mobilization was passed. If anyone believes that while someone is fighting far away at the frontline and risking his or her life for this state, someone else is staying abroad but receiving services from this state, then this is not how it works.

Staying abroad does not relieve a citizen of his or her duties to the Homeland. That is why yesterday I ordered measures to restore fair attitudes toward men of conscription age in Ukraine and abroad. This will be fair.

Soon, the Ministry of Foreign Affairs will provide further clarifications on the procedure for obtaining consular services within the legal framework for men of conscription age in foreign diplomatic missions as we approach the entry into force of the law "On Amendments to Certain Legislative Acts of Ukraine on Certain Issues of Military Service, Mobilization and Military Registration", as well as after it comes into force.

Russian missiles against our cities and people. The strike on Lviv killed 5 people, including a 14-year-old girl. My condolences go out to the families and loved ones of the victims. More than 30 people were injured. Ordinary residential buildings, schools, and medical facilities in the city were damaged.

In the Russian attack on Kryvyi Rih, 5 people were injured. Homes and civilian infrastructure were damaged. Our emergency services are on site, doing everything necessary to eliminate the aftermath of the attack. All the injured are receiving the required assistance.

Every one of our partners around the world who helps Ukraine with air defense is a true defender of life. Anyone who convinces partners to provide Ukraine with more long-range capabilities, enabling us to respond justly to terror, is working to prevent such Russian terrorist strikes on Ukrainian cities. Terror must be stopped.
