Wuthering Waves PS5 Performance Test • Test Setup PS5 Slim (brand new, clean, no dust) Room temperature: 22°C with AC • Map Issue Yes, it's real. The new map is locked to around 2 FPS when opened from the menu, making it extremely laggy. • Stuttering Problems The game has severe stuttering. In some areas, it even freezes for 4–5 seconds, making the experience frustrating. • My Observation From my testing, the game appears to be running at a very high internal resolution on PS5 instead of relying on aggressive upscaling. For example, DLSS Quality at 1440p renders the game internally at approximately 1707×960 before upscaling it to 2560×1440. On PS5, however, it looks like the game is rendering at or near 2560×1440 internally and then upscaling to 4K. If that's true, it's an extremely demanding target for a base PS5. • Is This Fixable? Yes. If the game is indeed using such a high internal resolution, lowering it and using better reconstruction or dynamic resolution scaling could significantly improve performance. Running at such a high internal resolution on a base PS5 doesn't make much sense, and the game has suffered from performance issues for nearly 12 months. • Final Thoughts Kuro Games needs to address this. At this point, we can't keep blaming players, their hardware, or the engine. If the high internal resolution is the cause, it should be adjusted. If it isn't, then something else in the game's optimization is seriously wrong. #WutheringWaves #Gacha

In May 2023, a live streaming world record was set with 32 million concurrent viewers watching the finale of the IPL cricket game. How was this system built? Ashutosh Agrawal was the architect behind this system, and he walks us through how live streaming at scale works, how the system was built and tested, and other interesting learnings. Watch or listen: • YouTube: • Spotify: • Apple: --- Brought to you by our wonderful sponsors: • WorkOS — The modern identity platform for B2B SaaS • CodeRabbit — Cut code review time and bugs in half (use the code PRAGMATIC to get one month free) • Augment Code — AI coding assistant that pro engineering teams love --- Three of my biggest takeaways: 1. The architecture behind live streaming systems is surprisingly logical. In the episode, Ashutosh explains how the live streaming system works, starting from the physical cameras on-site, through the production control room (PCR), streams being sliced-and-diced, and the HLS protocol (HTTP Live Streaming) used. 2. There are a LOT of tradeoffs you can play with when live streaming! The tradeoffs between server load, latency, server resources vs client caching are hard decisions to make. Want to reduce the server load? Serve longer chunks to clients, resulting in fewer requests per minute, per client… at the expense of clients potentially lagging more behind. This is just one of many possible decisions to make. 3. “Game day” is such a neat load testing concept. The team at Jio would simulate “game day” load months before the event. They did tell teams when the load test will start: but did not share anything else! Preparing for a “Game day” test is a lot of work, but it can pay off to find parts of the system that shutter under extreme load. See more takeaways and a summary here: Thanks Ashutosh for all these behind-the-scene details!

Ran 21 km (13.1 miles) — and the motor was still cold. That’s the detail that matters. 🤖 Honor was the clear dark horse in this year’s robot half marathon. They swept 1st, 2nd, and 3rd, and also posted a strong top-6 finish overall. What stands out to me is that this was not just about bigger motors, or a gait tuned for long-distance running. They seem to have solved something more important — cooling. In a post-race interview, Honor engineers said the robot used liquid-cooling tech adapted from Honor smartphones, with cooling lines running deep into the motor system to carry heat away. Some reports added more detail: the setup used two high-speed micro pumps, with flow rates reaching up to 6 liters per minute, giving the system enough cooling capacity to handle sustained lower-joint motor load. That matters because once a robot starts overheating, output drops, stability goes with it, and the whole run can fall apart fast. And that’s exactly why this detail is interesting. Of course, that does not mean Honor has already surpassed teams like TienKung or Unitree across humanoid robotics as a whole. What it does suggest is that for the marathon task, they built a very strong system solution. And honestly, that alone is already a useful case for the industry. The bigger trend is moving fast. Last year, TienKung won in around 2 hours 40 minutes. This year, the winning time dropped to 50 minutes 26 seconds. Last year, most robots were still fully remote-controlled or only semi-autonomous. This year, around 40% were running with a much higher level of autonomy. So to me, the real signal is not just that robots got faster. It’s that the field is now moving past raw speed, and into the harder problems: autonomy, stability, and system reliability under load. If the pace of progress stays anywhere close to this, then next year’s race should be even more worth watching.

Before LNG is loaded into a tank, the tank must be properly prepared through a series of controlled stages. This preparation is critical to ensure safety and to prevent damage due to extreme temperatures. An LNG tank is fitted with different lines, each serving a specific purpose: filling lines, spray lines, discharge lines, and pumps. The first stage is drying. The tank may contain humid air, which can lead to ice formation at low temperatures. To prevent this, dry air is introduced from the bottom of the tank through the filling lines to displace the moist air. Next is inerting. After drying, inert gas is introduced into the tank to purge out the dry air. This step is important to eliminate oxygen and reduce the risk of forming flammable gas mixtures. The third stage is gassing-up (vaporizing). Since inert gas contains carbon dioxide, which can freeze at low temperatures, it must be removed. Warm LNG vapor is introduced through the spray lines to displace the inert gas and prepare the tank for cooling. Then comes cooling down, which is a critical stage. The tank must be gradually cooled to avoid thermal stress that could damage the structure. Cold LNG is sprayed into the tank through spray nozzles, bringing the temperature down to about -110°C to -130°C. Finally, the loading (filling) stage begins. At this point, the tank is ready to safely receive LNG, and the cargo is loaded through the filling lines. In simple terms, the process moves from removing moisture, to removing oxygen, to introducing gas, then cooling the tank, and finally loading the LNG.

According to fick's law, the more moisture that's in your flower, the more water it will diffuse faster. This means that almost 80% of the water in your plants is gone in the first phase (constant rate)of drying, which, condition depending, can be the first 18 hours to ..🙄3 days according to *Challa 2020-KINETICS AND THE EFFECTS OF DRYING METHODS ON QUALITY OF (C*****s s****a L.) BUDS* Water adhesion principals state that with the surface moisture evaporated, water is less susceptible to the evaporative forces applied on it (falling rate). During this falling rate, your 60/60 is far less effective at pulling water than it was during the constant rate (which still wasn't ideal). Once we enter the second phase of drying, or the falling rate; dehydrated surface exposure, along with low water activation energy in that dehydrated flower means dramatically increased secondary metabolite oxidization. In effect, from this moment forward, that PSM count is going DOWN The longer we keep it on the rack, and not into cure, the faster this will happen In the study *(Basel). 2022- Postharvest Operations of C*****is and Their Effect on C****binòid Content: A Review, it was shown that significant secondary metabolite loss occurred at temperatures higher than 40°c . Below this number, the rate of degradation was relatively constant. As referenced in the above studies. The difference in secondary loss between drying at 71° vs. 77 or even 89° tends to be only 1–2 % with a net positive moisture loss, whereas time driven degradation over days to weeks can account for 30 % total loss or more. Meaning that temperature does affects secondary volatility, but the timing of drying matters WAYYYYY more So how am I drying these? Day 1 - 72°f 55% Day 2 - 72°f 55% Day 3 - 74°f 52% Day 4 - 75°f 50% Day 5 - 75°f 50% See the article on and citations. Share, repost, follow. Still not convinced? Google "sharkmouse drying" on Google and see what reddit has to say!

Macchi C.205 pilots of the Aeronautica Nazionale Repubblicana with their fighters still in Luftwaffe markings in early 1944 full clip: The Aeronautica Nazionale Repubblicana was the air force of the Italian Social Republic, the World War II German puppet state in Italy after the 1943 armistice divided the nation. It received numbers of Italian aircraft, later augmented with their own local production, and further aircraft from Germany. This force was opposed to the Aviazione Cobelligerante Italiana, the Italian pro-Allied air force, though they never actually met in combat. The Macchi C.205 Veltro was an Italian World War II fighter aircraft built by the Aeronautica Macchi. Along with the Reggiane Re.2005 and Fiat G.55, this plane was one of the three "Serie 5" Italian fighters built around the powerful Daimler-Benz DB 605 engine. The C.205 was a development of the earlier C.202 Folgore. With a top speed of around 640 km/h and equipped with a pair of 20mm cannon as well as 12.7mm Breda machine guns, the C.205 was highly respected by Allied and Axis pilots alike. Widely regarded as one of the best Italian fighters of World War II, it proved to be extremely effective, destroying a significant number of Allied bombers. The Macchi C. 205 also proved capable of meeting advanced Allied fighters on relatively equal terms. While able to match the best Allied opponents in speed and maneuverability, the type's impact was limited as it was introduced late in the conflict. Due to the limitations of the Italian war economy, only a small production run was delivered before the end of the war. Like the Spitfire, the Veltro was challenging in its construction and slow to build. Italy's highest-scoring ace, Adriano Visconti, achieved 11 of his 26 credited victories in the few weeks he was able to fly the Veltro, with Sergente Maggiore pilota Luigi Gorrini shooting down 14 enemy aircraft plus six damaged with the C.205. A total of 29 C.205s reached northern airfields to be used by the Aeronautica Nazionale Repubblicana. Macchi produced the remaining 72 aircraft of the third series for the ANR before production was shut down by Allied bombing in May 1944. Statistics on aircraft production post-Armistice are unclear and incomplete. In general, C.205s fought well in ANR service: they were attached to units that had homogeneous equipment, or at least of comparable quality, and were guided by German radar stations. Though few in number, they achieved success in inflicting losses on Allied bombers and fighters. A few Veltros were delivered to 3° Gruppo, based in Vicenza, while further Veltros were scattered throughout other small units. The 1° Gruppo C.T. of the ANR based at the Campoformido airfield was equipped with C.205 and its first operation on 3 January 1944 was a success. led by Italian ace Capitano Adriano Visconti, a formation of Boeing B-17 Flying Fortresses and their escort of Lockheed P-38 Lightnings bombing factories in Villar Perosa was intercepted, and four of the escorts were shot down. The aircraft were still in Luftwaffe markings as seen in this footage. On 28 January, the C.205s, now with Italian markings, succeeded in shooting down a B-24 Liberator, their first four-engined American bomber. This air victory was credited to Sergente Marconcini, Visconti's wingman. By 25 February, 1° Gruppo C.T. had reported 26 victories for nine losses. An extremely bitter aerial combat took place on 11 March, where the Italians claimed 12 victories while losing three of their own pilots. These included 1st Lt Boscutti, who was reportedly killed by gunfire from a US P-38 Lightning after he had bailed out from his stricken fighter and was hanging from his parachute. On 18 March, 30 C.205s from 1° Gruppo C.T. and 60 Bf 109s from JG.77 tangled with about 450 Allied bombers and their escorts, shooting down at least four enemy aircraft. Corp. Zaccaria was killed in action, again apparently shot at by a P-38 after bailing out. Allied bombing in April 1944 destroyed most of the Macchi and Fiat facilities, bringing fighter production to an end. With production interrupted, the Italians were forced to re-equip their three groups almost fully with Bf 109s, largely because the Germans were quick to offer some of their best models, including Bf 109G-6s and Bf 109K-4s. The Allies were less generous with the Aviazione Cobelligerante Italiana, and Veltros, including some upgraded C.202s, were slowly replaced with worn-out P-39s and Spitfires, but not before Summer 1944. #macchi #c205 #veltro #anr #ww2 #wwi #sgm

Last week, we pushed our Hadfield MK IV engine and Darkhorse engine test cell to their limits ahead of our upcoming thrust vector control (TVC) and orbital engine test campaigns. It was thrilling to see this controlled test go sideways — literally! Orbital launch vehicles operate within narrow design margins and constrained safety factors, where excess mass in any subsystem directly impacts payload capacity or mission viability. Destructive and limit testing enable us to validate optimal mass-performance trade-offs across propulsion, pressure systems, and primary structures. Key outcomes from this test include: ✅ Structural margins validated – Darkhorse demonstrated stable operation under full thrust loads at gimbal angles exceeding design specifications ✅ Thermal performance characterized – Extended burn duration at off-nominal mixture ratios provided empirical data on regenerative cooling degradation modes and injector thermal limits ✅ Fault tolerance demonstrated – Engine maintained functionality despite progressive damage, validating robustness for anomalous flight conditions ✅ TVC readiness confirmed – Test results validate system integration for upcoming actuated TVC test series l Design optimization insights – Failure mode analysis generated actionable improvements for cooling architecture, injector design, thrust structures, and engine reusability At NordSpace, we push limits. Canada needs to get to orbit with sovereign light-lift launch by 2028 and medium-lift launch by the early 2030s. The only way this is possible is through extreme levels of testing, manufacturing, and investment. Our mission to build a Canadian end-to-end space missions capability will change the shape of our nation both on Earth and in space. If you would like to join our mission, please apply for a role at NordSpace via the Careers page on our website, and join us at the Canadian Space Launch Conference on May 5th, in Ottawa.

So Jacob Terkelsen, a PC diehard with a history of inaccuracies, did an apples to oranges PC comparison to try to prove Black Myth WuKong's game director was lying or wrong (lol) about Series S's ram limitations coupled with a lack of optimisation experience, being the cause for the lack of an Xbox release. Here's my video debunking him and highlighting numerous inaccuracies and/or misleading aspects to his process, conclusions and data. I've also included a second video where I debunked some of the past things he was also spectacularly wrong about, with similar misplaced analysis and poor methodology. Finally, here is a link to a debate we had in Spaces on X on this subject. Discussion from 3:33:00 onwards. There have been over a dozen studios/devs who have complained about the Series S now, including on memory issues specifically, potentially breaking NDA to do so. But of course, the fanboys continue to try to discredit the developers actually working on these consoles, the folk making the games for this hobby we love, all to pander to their own insecurities and headcanon ideals. Imagine discrediting devs who are willing to share more insight than they ought to, when we should be embracing the insider info. And imagine thinking your own typical play test was equivalent to thousands of hours of QA testing to find worst case scenarios in the game, and of peak ram use. Embarrassing. I should add, I'd imagine the majority of Black Myth WuKong likely runs absolutely fine on Series S. But game optimisation is often about ironing out a minuscule minority of worst case scenarios or issues. Even a handful of problematic areas or instances in a game, could prevent release or certification. Especially if they're egregious (repeatable crashes, bugs, VRAM topping out in a specific scenario etc). #PS5 #SeriesS #BlackMythWuKong

This is a demo of our new thermal plume simulation that we're incorporating into all of Nukit's CFD aerosol modeling. With the current pathogen chamber tests that Nukit obtains from third-party labs, we measure how well Far-UVC removes bioaerosols that are introduced into the chamber through a port in the wall. This is a good measure of overall effectiveness, and all our Far-UVC products are validated in this way and the data provided to the public on our site - (we are, so far, the only company willing to put our money where our mouth is in this way). The only problem with this testing method, is that it does not test one of the main strengths of Far-UVC- the ability to mitigate near-field transmission- the transmission of pathogens that occurs at close range between individuals. This is where computational fluid dynamics (CFD) modeling comes in. The same powerful software that is used to model the flow of air (a fluid) to make sure an airplane design will fly before it's even been built, can model the air we exhale and how it will respond to Far-UVC with similar accuracy- if it's given enough data to work with. One of the trickier things to calculate with this kind of modeling is the human thermal plume- how the air we exhale rises and then falls as it cools, and how the heat our bodies emit pulls air- and any suspended aerosols, upward. Knowing how the air we exhale moves before it's inevitably inhaled by someone else lets us figure out how much Far-UVC we need to inactivate the pathogens that air contains before it's inhaled, and how that Far-UVC should be arranged. One popular method of implementing Far-UVC is with downlights. The idea is that the vertical cones of light would interrupt the exhalation passing horizontally between individuals. But, if the exhalation is not strictly lateral, if most of it is rising first on a thermal plume, it might miss a few staggered vertical cones of Far-UVC, and having emitters in the corners, pointed slightly horizontally to cover a broad area and more of the upper room, might inactivate pathogens as they rise before they cool and fall- a bit like Upper-Room GUV but lower. The next step will be to model this with a number of “breathing” figures, sitting and standing, and seeing, with the same total Far-UVC wattage, what arrangement of emitters results in the lowest inhalation of exhaled active bioaerosols. This model shows: - No ventilation (0 ACH, it will be 3 ACH in the actual model) - Air temperature: 25 C - Skin temperature: 34 C - Nostril temperature: 36 C If you’d like to read more about human thermal plumes and their role in how bioaerosols propagate, see: Nukit Torches are no longer sold- we will still honor warranties on them. The Torch 2 will be available in the next 60 days or so. It is more powerful, lower cost per watt, and has replaceable emitters and batteries. For US residents we currently have a limited number of Nukit Lanterns in stock in our US warehouse, that are tariff free. This may be the last chance to obtain them without tariffs. Outside of the US you can buy them here: A small number of this batch of Lanterns have defective buttons. If you have any issues, please contact us. Our apologies; we are trying very hard to make Far-UVC affordable for everyone, and patient, understanding early adopters help make that happen. We do not check this account often, if you have any questions about Far-UVC kindly contact us through our website.

⭕️ Russian Minister of Defense, Andrey Belousov: “Striving to maintain global dominance, the United States of America and the collective West are destroying the foundations of the global security architecture. Their aggressive course exacerbates geopolitical contradictions, undermines strategic stability and key peace agreements,” According to the Russian Defense Minister, the world has "significantly increased its conflict potential". “At the same time, the role of international institutions has decreased,” he noted. “We are solely in favor of a diplomatic path to conflict resolution. We welcome the efforts of the SCO countries, including Pakistan, aimed at ending it. This is an important step towards restoring stability in the Middle East,” said the Russian Defense Minister. Noting that the USA and Israel carried out an attack on one of the SCO member states - the Islamic Republic of Iran, he stressed that "the Russian Federation at all levels strongly condemned this unprovoked aggression". “Once again, we express our condolences in connection with the irreparable loss of Iranian state and military figures, as well as civilians, including children, who died as a result of US and Israeli strikes,” said Andrey Belousov. He also stated that Russia considers unacceptable the attempts of non-regional states to ensure a military presence and solve logistical tasks in Central Asia, and is seriously concerned about the situation in Syria, Lebanon, and the humanitarian catastrophe in the Gaza Strip. “There are risks of militants from crisis zones penetrating into neighboring countries. Including into the SCO space,” noted the Russian Defense Minister. “Instability in Afghanistan persists. It remains the main source of transnational crime and terrorist threats,” said Andrey Belousov. He also emphasized that "the destructive influence on stability continues to be exerted by the activities of the United States in the Asia-Pacific region". “Their desire to reform the regional security system to an American-centric one at the expense of strengthening the military-political structures controlled by Washington. Such actions provoke tension, undermine regional stability, and increase the risks of armed conflicts,” stated the Russian Defense Minister. “There has been a decrease in the activity of the United States of America in supporting the Kiev regime against the backdrop of increasing assistance to Ukraine from European countries. The European Union is increasingly drawn into the conflict, finances it, and supplies weapons,” said the Russian Defense Minister. At the same time, he noted that the production and logistics chains of Western weapons supplies to Kiev are being closely monitored and deliberately made public. In particular, Andrey Belousov recalled that on April 15, a list of European enterprises producing and supplying attack UAVs and their components to Ukraine for strikes on Russian territory was published in the media. “Such actions contribute to a sharp escalation of the military-political situation on the entire European continent and can lead to unpredictable consequences,” said the Russian Defense Minister. 🔹 Russian MOD
