macbook pro – Why can’t I use the windows 10 boot stick I created for my MBP?

I want to install Windows 10 on my MBP (early 2011, 15″, high sierra). I followed instructions using BootCamp and got to successfully create a USB stick with Windows 10. At the end of the boocamp procedure nothing happens (according to the user guide I expected mac to restart). When I restart, I get regular high sierra start. When I restart holding option key, I have a single choice for booting on my ssd, but the usb stick seems undetected.
Thanks for helping!

Mount AWS S3 on boot while behind proxy using s3fs

In order to get a mount to work I have to first set the http_proxy environment variable before I run s3fs.

export https_proxy=<proxy address>
s3fs -d <bucket> mount-point -o url=https://s3.us-gov-west-1.amazonaws.com -o use_path_request_style

I’d like to mount my S3 bucket on boot but I am behind a proxy. I can add it to fstab, but it doesnt work because it doesnt know about the proxy.

Asus laptop – what LED error codes on boot mean?

I have an Asus N580 laptop. When I turn it on it does not boot (no POST), black screen with no logo, fans are working, LEDs are blinking. What I want now is to understand what these LED errors mean:

  • Power LED is ON.
  • The battery LED is blinking white:
    two blinks and pause, then again two blinks and pause.

What I have tried to understand what these LEDs mean:

  • When I disconnect LCD cable on motherboard then battery LED blinks four times then pause. This definitely means no LCD.
  • When I take out memory it still blinks two times and then pause.

I could not find the meaning for Asus LED error codes anywhere on internet. Does anybody have the reference to the meaning of these Asus LED boot errors? Thanks!

Example of open api 3.0 maven plug-in spring boot using the smallest amount of external dependencies

I’ve used swagger codegen (now open api codegen) for a few years now (in my professional and personal projects). I am looking to create a tutorial on open api maven plugin, and in order to not confuse others, I would like it to use as little dependencies as possible (i.e. use the http client from the jdk instead of bringing in Apache http client). Additionally, I would like the dependencies that are brought in to be dependencies managed by the spring boot (version 2.3.0) parent BOM wherever possible.

Can someone please provide an example of this? For reference, I am using java 14 and spring boot version 2.3.0

Thanks,
Connor

boot – Make existing Windows installation bootable from USB3.1gen2 adapter

Background:
I have an nvme-SSD with Windows 10 installed, this was my default drive in the system.
Yesterday I swapped the wi-fi card in the system and with it a new nvme-SSD that contains Linux.
While Linux works fine (wifi too) I have trouble booting the old Windows install from this enclosure.
(UGREEN M.2 NVMe SSD Enclosure, USB C 3.1 Gen 2 to M-Key M&B-Key NVMe PCIe )

Disclaimer:
Previously I’ve used this setup with a friend’s nvme and we were able to boot Windows from such enclosure (so it’s possible). The only difference was that the target system did not have any other drive in it, while my does (Linux one).
(I would not like to re-open the laptop since it’s very fragile)
Before swapping nvmes I’ve used the enclosure to run Linux as an external system while Windows was the primary one installed directed onto the motherboard.

Problem:
My windows BSOD error is: INACCESSIBLE_BOOT_DEVICE. So after searching for some solutions I found those ones:

  1. make existing windows 10 installation bootable from usb:
    • by following the steps I was able to boot in the system in Safe mode but after rebooting, the error still applies.
    • the AHCI parameter in BIOS is not the solution since it was my previous default mode and windows worked fine.
    • I looked at the WinToUSB sfw but since I’m not able to fully load my windows system I cannot clone it.
  2. Can I boot Windows from an HDD via USB? inaccessible_boot_device:
    • I took a look at registers values and found that some usb drivers are not configured with 0x10, 0x14 boot_flags but since the time of writing of that post things changed and the solution is not always that simple, in fact:
  3. Booting from USB 3.0:
    • this article describes loosely (for me at least) how to make this procedure but raises new questions about which particular drivers I’m interested in promoting and which class type to assign.

Questions:

  1. Is there an update on how to make previous windows installs runnable externally without resetting the OS (I have lots of programs and wouldn’t want re-downloading them)?
  2. If the only solution is to clone the system and make it a WindowsToGo, will I be able one day to plug it in directly and still work?
  3. If I need to change boot_flags for drivers which one I need to change? Is there a detailed procedure?
    Changing drivers boot flags could fix the problem (I remember that in Linux I had to change the boot order of some of them to be able to load the kernel) but it’s very risky because I’ll need to change register parameters and not text files like in Linux.

bootcamp – Boot Camp requiring disk on High Sierra

I’m running High Sierra on my late-2009 iMac.

In the past, I’ve not had trouble installing Windows 7 with Boot Camp on older versions of Mac OS

But this time, I’m getting the following error before I reach the partition page:

The installer disc could not be found.

Insert your Windows installer disc and wait a few seconds for the disc
to be recognized.

Things is, I don’t have a Windows installer disk… I downloaded an ISO for Windows 8.1 from the Microsoft website.

It might be worth also pointing out that the disk drive on my iMac no longer works, I’m not sure if this is related to me using High Sierra or whether the drive itself has just died.

Does Boot Camp require me to install Windows from a DVD? I just want to install it from the .ISO file like everyone else.

I could possibly purchase an external DVD drive and then figure out how to create a bootable Windows disk using that… but that seems like a lot of effort for something that might not even work.

java – Migrar proyecto Maven Spring boot de Netbeans a Intellij Idea

Actualmente trabajo con Java Maven Spring Boot y Spring Cloud, la cosa es que uso el IDE Netbeans y cada proyecto tiene varios archivos xml de configuración propios de Netbeans. Como nbactions-api-demo-local.xml, otro nb-configurations-xml. Pero quiero migrar a usar Intellij Idea pero no encuentro mayor información de como replicar esas mismas configuraciones. Si alguien ya ha podido hacer eso o conoce mejor el ide de Intellij Idea que me pudera orientar ya que la documentación que encuentor no me dice mucho.

secure boot – Time Authenticated EFI Variable

I’m setting up custom secure boot keys on an Asus Z87I-Deluxe motherboard. On other computers I’ve setup with secure boot, I’ve been able to either write the PK, KEK, and DB keys into the EFI variables via the /sys/firmware/efi/efivars filesystem or I’ve been able to load them in via the BIOS menu. I’ve always used DER encoded x509 certificates.

On this board, I’m able to write to the PK, KEK, and DB keys in both manners and read the variables back after a reboot. However, the computer will not boot a signed UEFI image. It doesn’t give any errors, it just drops you back at the UEFI menu each time you select the boot device. I’ve verified the UEFI signature with sbverify successfully.


$ for file in PK KEK DB; do                                                                                                     
    sudo openssl x509 -inform DER -in /root/secure-boot/$file.cer -outform PEM 
      | sudo openssl verify -CAfile /root/secure-boot/$file.crt
  done

$ efibootmgr --verbose

$ sudo sbverify --cert=/root/secure-boot/DB.crt /boot/EFI/linux.efi
warning: data remaining(24749608 vs 24759224): gaps between PE/COFF sections?
Signature verification OK

The user manual for the Z87I mentions that when loading the variables in via the BIOS menu, they must be formatted as “a UEFI variable structure with time-based authenticated variable” (section 8.2.2, I presume?).

I’ve never seen another BIOS that requires such a thing and I’m not aware of any software that can generate the required format.

Am I interpreting this correctly? I’ve tried writing straight DER and PEM files without any success.

boot loop – Asus zenfone 6 E: mount / cache failure

The phone hangs when loading the startup.

clear data / factory reset gives
E: mount failure / caching error

clear cache partition
also fails.

abd sideload also give
E: mounting / cache failure
Unable to open vs ..

Many of the same articles suggest TWRP but I don't have it. Didn't understand how to install it on a phone can not open.

Many others say that the EMMC chip is dead. I hope not. I know it is very likely but I want to try other options first if I can.
