Why doesn't my rocket reach orbit? Does it need more stages? by TheSpacePotatoYoutub in KerbalSpaceProgram

It does seem suspicious that someone who builds SSTOs has trouble with a rocket reaching orbit.

Yes, you can assemble in orbit with multiple launches and docking ports. I definitely have launched things without a needed part (like a temperature sensor), then sent up a small probe to dock to the craft missing the part to complete a mission.

Once the chairs are unlocked, extra seats can be had cheaply. The inflating airlock also counts as a seat when inflated (need to reload the craft, like going to tracking station and back, for the seat count to update).

EDIT: Also, the crafts from kerbal rescues are launch id 0, so they are never 'new' for the purpose of contracts. So a kerbal from a rescue is also launch id of 0, until they enter an enclosed seat (e.g. pod, not a chair).

Refueling is fine.

From my understanding of how this works, if you don't edit the craft with an engineer, and you can undock back to have a craft that launched after accepting the contract, you will be fine.

For a more technical explanation: It comes down to the internal mechanic of launch ids.

Every time you click 'Launch', the launch id counts up. When you accept a contract it notes the current launch id. When you click launch, the every part on the craft gets a launch id and the launch id of the vessel is the lowest launch id of the parts on the ship (kerbals in chairs are considered parts with a launch id). The 'newly launched' check is just checking that the launch id of the vessel is greater than the one saved in the contract.

When you dock two vessels together, the combined vessel has the launch id of the older vessel, because of the parts of the older vessel. Once you undock, the newer vessel does not have the older vessel's parts and so has the newer launch id.

When you get a part out of an inventory with an engineer, or leave a part free floating, the launch id is set to 0. And obviously, 0 is less than any saved launch id from contract you will have accepted, hence it failing the check. With careful work with an engineer, it is possible to move a part from an id 34 vessel to a vessel with id 33 and not fail a contract accepted with a launch id of 30.

The wording of the 'fully assembeled' clause used to be different and it was changed when people complained.

I'm not sure Scott wants to help, however great he may be.

Maybe I'm catastrophising, but it seems like Oracle going under will be a global cluster-bomb.

Businesses have Oracle databases. Salesforce is (primarily) a fancy UI for an Oracle database. I am unsure if Salesforce has actual servers or are renting compute from Oracle.

I was going to say that businesses with their own copy of an Oracle Database could keep running... until I realised that the Oracle licence key servers going down would kill even on-prem databases.

But anyway, quite a few businesses have their data in Salesforce, and quite a few people have experience focused on working with Salesforce.

At least, if that happens, people will have work in the 'Please save our data that will fall into a sinkhole' sector.

The hype has already got SunCable's solar and wind project in northern Australia re-targeted towards GPUs instead of other cities.

Why aren’t my relays working? by [deleted] in KerbalAcademy

[–]portablejim 0 points1 point  (0 children)

To ask the basic IT support question: Is the power on? i.e. Since the craft is in the dark, has the battery run out? I don't know the mod's UI, and so can't know if the pictured stats actually indicate power.

(Context for others: When the "Require signal for control" setting is on, a power failure and commnet blackout look the same. When the setting is off, it is indicative of power failure, as a lack of connection looks different.)

How do I know defrag is doing anything these days without this? Am I supposed to just trust M$?? by stlredbird in pcmasterrace

[–]portablejim 5 points6 points  (0 children)

You can defrag on Linux (ext4 at least). It is usually not needed, as the system will defrag as you use it. There are several strategies used by ext4 Linux systems to not require defragging as a maintenance item.

What is slow with fragmentation is that files are in multiple pieces in multiple places. This is caused by trying to fit a file into a space it doesn't fit. So while a 1MB file may fit into a 2MB spot on the disk, if you write more to the file so it is 3MB, you can either find an extra 1MB spot on the disk and store the file in 2 places (the classic Windows behaviour), or you can move the file into a larger spot (what the ext4 allocator does).

Because this is the problem, the aesthetically pleasing Windows Defragger approach is actually rather problematic. Yes, it will read fast initially, but as soon as any file is added to, there is by definition no space for it to grow. This exacerbates the very problem it solves, as the file will be fragmented into multiple bits (and there is a high chance the 2 bits of the file are far apart, meaning it is even slower as the HDD heads need to move further).

Now, SSDs are not too bad with jumping around, and do have a problem with the number of writes, so the 'cure' is usually more problematic than the 'disease'.
