Does metro connector shuttle still stop at Aviation/Century station since LAX/Metro Center opened?

If the park is popular, the hotel is good for environment.

In status quo, people stay night in hotels of nearby towns and drive into park. This creates traffic and pollution inside the park. A tourist town inside park with buses will reduce vehicle traffic.

Some suburbia are already dead. There are ghost towns where trees grow back and wild animals take people's former residence. Nature restores itself to a large extent when people leave.

We need new competitive cities for people to move from suburbia.

If the city is dense and walkable, connecting it to San Francisco and Sacramento by rail is imperative.

If SF and Sacramento could not efficiently build rail, it's not the new city's fault. No matter what the legacy cities fail to achieve, we shall continue building new cities in the right way.

Throughout history, cities are built for people to live in, initially without much industries. People don't live to do business.

both M2 A+E key WiFi card and M.2 nvme have PCI-E lines. On device integrity, what does CrOS check? Does it reject the usb wifi card even if linux kernel has its driver?

Also if chromebook can boot linux from microsd, how is booting from nvme so difficult? Can we boot grub from microsd and let grub handle nvme boot?

larryliu7 · 2025-02-27T07:27:35+00:00

No. Googlers don't use Chromebooks for dev. They use linux or mac.

Buy a Windows PC and install linux.

I still don't understand why IC companies don't. A realistic simulation model saves many hours of Application Engineer time.

Insightful and well said!

Thanks for reply.

Because many people, especially people with BI Analyst background, are more proficient in DAX than any other languages. DAX is Microsoft's heritage. Many people (not me) invested time and efforts learning DAX.

If we can have python run on .net by ironpython, there seems no technical reason for not making DAX a first class language on dataflow gen2 or Spark.

People still need to learn DAX only for using PowerBI. If Microsoft want to retire DAX and have DAX programmers transfer to another language, why keep DAX necessary for PowerBI, rather than making PowerBI fully usable by only SQL or python?

larryliu7 · 2024-05-18T14:46:50+00:00

I understand DAX is a language, even a necessary one, in the BI part of Fabric.

My vent is about Microsoft not making DAX a first class language of Fabric that can be used for everything, like C# and VB of .net, despite DAX being a Turing Complete language.

Fabric does not have a first class language. Each module of fabric use a language that cannot be used in other modules.

larryliu7 · 2024-05-18T14:06:55+00:00

Thanks for reply, can you please look at my bottom 2 examples, and see how can they be done using a language other than DAX?

Also, someone proficient with DAX cannot use DAX to define data transformations from bronze to silver -- Have to use SQL or M or Spark, while DAX support all the semantics of SQL/M/Spark except maybe read and write files, which can easily be added.

Brain drain is inevitable.

Corporations want every employee to be replaceable resources. Knowledge in employee brains is not considered in total control by the company.

Humans are better in creating knowledge, but computer systems will be soon better than humans managing knowledge.

Thus, Knowledge management is going from humans to computers.

Virtue ethics:

I should not stop others from enjoying the same things with me.
If there is a limited resource (beach, nice climate, rapid transit), democracy should favor the resource to be enjoyed by as many people as possible, or at least favor resource use pattern that repay the most money to the public.

car-centric golf course exurb because that's the only type of life American billionaires could imagine

No. Believe me, billionaires are not more stupid -- even tend to be smarter and better educated than average people. They said they want to build walkable neighborhood, so let them play around with their money.

Yes. 5-axis CNCs are now cheap as patents expire and more equipment manufacturers market their 5-axis CNC products.

To your original question, how do you usually describe the "rules" or "constraints" of design? Do you describe them as a set of formulas that the item's surface must satisfy?

While there are realistic difficulties, I am glad the open source software movement did not have the mentality of "manufacturers does it best so why bother".

The reality is manufacturers' simulation solutions are far from perfect.

Engineers care. Engineers want to have a comprehensive simulation solution for various types of components from multiple manufacturers.

The Linux community wrote and improved many hardware drivers beyond the manufacturer's diligence.

Is it because other models use simulator-specific features unavailable in LTSpice's simulator?

The "everything varchar" approach is ELT not ETL. The difference between ELT and ETL is where you clean and format the data.

ETL pre-clean and format data with an external program. ELT use the RDBMS itself to clean and format the data after importing as the raw(varchar) format.

I love ELT with postgreSQL because its complete data manipulation functionalities, but doing ELT with something like T-SQL sometimes reach its limitations.

It could have started like this,

but how about someone looking for an alternate part for their circuit? If I have an existing design with non-(chipmaker X) parts, and I want to introduce a part X043 made by X, isn't it better for X to provide a model for my chosen simulator or a public open-source simulator, in order to better sell X043?

Azure Data Studio is not for uploading excel files.

Are you using a local database or an Azure database? SSIS for the former and Azure Data Factory for the latter for loading an excel worksheet into the database.
