System Installation – The laptop can not boot after clean installation to a single boot drive using ubuntu-18.04.2-live-server-amd64.iso

I can only offer the following observations:

  • laptop: an HP Elite book (6930p) with Intel Dual Core with only
    "UEFI startup experimental support". its bio setting: the UEFI mode is
    disabled.
  • I used Rufus 3.4 to burn an 18.04.2 server iso on a USB stick
    with "Partition Scheme" as MBR and Target System as MBR or UEFI.
  • the usb key can install the ubuntu server without any problem ("use all the disk" option)
  • after reboot, the system can not start

also:

the same laptop can be properly installed and started in tty using:

  • mini.iso
  • old iso style server (ubuntu-18.04.2-server-amd64.iso)

The common point between these successful ISOs is the following: at the end of the installation, it invites you to write grub in the MBR. This process did not exist for live iso installation. During the live installation, all I got is a mandatory "bios_grub" partition of 1 MB that you can not modify or delete. I think the "bios_grub" is the same as the "write grub in the MBR". But the damn thing just does not start after installation.

Something weird about iso live-server?

How to clean the Minolta X-700 viewfinder

My Minolta X-700 has been abandoned, resulting in a dust-filled viewfinder like this:

I do not know how to clean it except remove the top cover to reach the viewfinder. Is there another possibility?

Help me, please.

Thank you.

orm – Clean Architecture and Entity Framework

I have encountered few problems when generating the database schema from business objects with EF Core:

  • No support for struct properties
  • No support for interface properties
  • I need extra columns that need to belong to the data layer only.

I do not wish to modify my management layer (structures / interfaces in classes) only because of EF, because this goes against the principles of clean architecture (the structure should not serve your application, but l & # 39; reverse). It is also out of the question to add persistence-specific columns to the management layer.

I guess the good thing to do is to add persistence objects to the persistence layer that would represent entities in the management layer.
In addition to this, some mappers should be used by the business layer to summarize persistence objects by mapping them to business entities.

Few questions about this approach:

  • Is it a good thing to do? Are there alternatives? For example: EF configuration capabilities that would help solve the problems listed above without replicating the entities in the persistence layer?
  • This looks like a lot of boilerplate code and replication of the same properties. It looks like this code could be generated automatically by a tool. Is there anything like this?
  • Is there a good example of the appearance of such an approach?

smartphone – What are the best apps to keep your Android device clean and malware free?

Windows has items such as the origin of the Ublock, malwareware, anti-rootkits, adware detectors, and so on. So I wondered if Android also had a good set of applications that could detect most or all malware. I might be able to do a search on Google, but I trust ordinary users, and even more, paid search sites.

UV + VIS light detection cameras / optical filters with short bandwidth, clean cut

Are there any DSLR conversion services or cameras available with sensors that allow the simultaneous detection of UV (~ <330-395 nm) and visible light ~ 395-700 nm? Maybe with a lower sensitivity of 1,000 times at the VIS range to mimic sunlight on the surface of the Earth?
As a related question, where can one create a "short" short-circuit in the short run? [<~720 nm (<700-750 nm)] filter be obtained? I thought Hoya was making such an optical glass, but all I can find from there and apparently most of the other sites are high-cut filters. Any help would be appreciated!

tagging – How to clean hierarchical tags when adding new levels in Digikam?

I guess you're not able to do that, because that would defeat the purpose of nesting.

You can create the same tag a second time outside this hierarchy, but the point of

Animal
Mammal
Cat
Human
Insect
bumblebee
Ant

Is Ant and Cat are the two Animals, but not all Animal is a Mammal and or Cat.

Therefore, when you search for the tag Animalyou will find all Animals. When you search Mammals, you will only find Mammals – and so on.

If, on the other hand, you had a flat search:

Animal
Mammal
Cat
Human
Insect
bumblebee
Ant

then there is no way that a picture only tagged Cat will be found by searching Animal.

In theory, you could have a routine that does the hierarchy automatically, so while the image contains only the tag Cat, your program puts it in Animals etc. I do not know if DigiKam (or any other program) can do it, and it probably would not be the best idea, because it's possible that the tags are ambiguous (for example, Cat also reference to Caterpillar Inc. machines).
