Need some PHP programming help (paid)
by Evan Leibovitch 04 Apr '18

04 Apr '18

Hi, I have an associate with a problem on their website, that could be a source of paid work top someone with the chops to fix it. Specifically, the immediate issue involves fixing a module that handles the interface between the Zencart shopping system and the Moneris ("hosted pay page") gateway. There are some issues with display and information passing between the two that are almost there but not quite. It works for the financials but the UI needs work. I suspect that for someone who knows what they're doing this might not be a big job and might be less than a day. If it works out there may be followup support and upgrades of their wordpress systems, at least one of which is fairly complex and multilingual -- but no promises. The client is in northwest 416 accessible easily by transit. The systems are all hosted on-site behind a firewall that they won't give access to from off-site -- meaning that at least some of the coding work will need to be done on location. Let me know if you're interested. -- Evan Leibovitch Toronto, Canada Em: evan at telly dot org Sk: evanleibovitch Tw: el56

parted and fdisk disagree
by Darryl Moore 04 Apr '18

I have an SD CARD disk image which I can burn to an SD card ant it boots up my Olimex board just fine. When I try viewing the partition information with parted and fdisk, I get different information. Ive googled this but come up empty. Anybody have any idea what is going on here? fdisk is the correct answer..... I think. darryl@darryl-Aspire-V3-575:~$ sudo parted elp780.3.3.img print Model: (file) Disk /home/darryl/elp780.3.3.img: 16.1GB Sector size (logical/physical): 512B/512B Partition Table: loop Disk Flags: Number Start End Size File system Flags 1 0.00B 16.1GB 16.1GB fat32 darryl@darryl-Aspire-V3-575:~$ sudo fdisk -l elp780.3.3.img Disk elp780.3.3.img: 15 GiB, 16088301568 bytes, 31422464 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x6f20736b Device Boot Start End Sectors Size Id Type elp780.3.3.img1 2048 34815 32768 16M 83 Linux elp780.3.3.img2 34816 31116287 31081472 14.8G 83 Linux

PC build recommendation
by Alex Volkov 04 Apr '18

04 Apr '18

Hey everyone, I'm assembling a computer and I'm looking for some feedback. The computer I'm building I'll use for development, run some VMs, edit video time-to-time. I also already have a 1Gb hard drive which I plan to use for VMs. One of the big requirements is to be small size, lots of memory (eventually upgrade to 32GB) and have a somewhat beefy CPU (Thus Ryzen 2400G). I've chosen Asrock AB350 mini ITX because it's small and it's got dual HDMI. I'm thinking maybe I can reduce some specs to save a few bucks. Thanks, Alex.

Linux container options on Windows
by Alex Beamish 03 Apr '18

03 Apr '18

Hi All, The technical challenge I'm trying to solve is to provide an off-line version of an API that runs on a laptop. This API would be primed with the appropriate data set from the cloud, then would be used off-line during data entry. Data would only be added, not modified or deleted during that time. Once back on-line, the cloud would be updated with the new data. It looks like Docker has a technical solution that runs a Windows VM inside Windows, but what I'd love to have is a Linux VM running inside of Windows that would have a self-contained web server and database. I could probably implement this in a Windows container, but it would be so much easier to do in Linux. Thanks for your thoughts. -- Alex Beamish Software Developer / https://ca.linkedin.com/in/alex-beamish-5111ba3 Speaker Wrangler, Toronto Perlmongers / http://to.pm.org/ Baritone, Board Member, Toronto Northern Lights, 2013 Champions / www.northernlightschorus.com Certified Contest Administrator, Barbershop Harmony Society / www.barbershop.org

Onavo VPN: Facebook wants your privacy
by D. Hugh Redelmeier 03 Apr '18

03 Apr '18

Onavo is a VPN feature that Facebook offers. It turns out that Facebook spies on this VPN traffic. And, once installed, spies on your traffic even if the VPN is turned off! Wow. I don't think that it works on Linux (except Android Linux). <https://www.findvpn.com/facebook-onavo-vpn-collects-user-data-even-when-it-…> <https://gizmodo.com/do-not-i-repeat-do-not-download-onavo-facebook-s-vam-18…> <https://techcrunch.com/2018/02/12/facebook-starts-pushing-its-data-tracking…> (My daughter pointed this out to me.)

fluentd index, key, forward to 2 places
by Aren.deJ 02 Apr '18

02 Apr '18

Has anyone has much mileage on fluentd? I'm trying to separate logs with fluentd, in a container that is receiving logs from many places. This fluentd container has several fluentd plugins installed, but I'm looking for the simplest way to gets logs indexed or keyed or grep'd differently as either of 2 things (application or system related logs) and have them send to the same outside ELK but with unique identifiers so that the app vs sys logs are easily differentiated. Any ideas? Or am I to continue trying to discern the fluentd docs? (The docs are actually good, but use-cases aren't all that great as examples) - Aren

war story: missing boot entry in UEFI
by D. Hugh Redelmeier 02 Apr '18

02 Apr '18

This may never hit you. I blame the problem on an early UEFI firmware (2012). Background: I had an old cute PC that I dusted off and then installed Fedora. - Foxconn nT-A3500 - the disk drive had decayed so I installed a new one (shucked from an external portable drive) - installed Fedora 27 in UEFI mode, then updated it - I then noticed a newer firmware and installed it + firmware installation required DOS + I fiddled with the boot sequence to legacy-boot a FreeDOS USB stick with the updates + applied firmware updates and shut down + the firmware was from 2012 -- quite old. No Secure Boot support. At this point, Fedora would not boot off the HDD?!?!? End of background The firmware setup pages seemed to offer no way to specify booting something from the HDD in UEFI mode. Quite odd. (Remember that there was a way before the firmware update.) The HDD had a proper EFI System Partition (FAT with type code EF00). I could boot the Fedora 27 live USB in UEFI mode. That was a reasonable platform for exploration. Beware: /boot/EFI points to something on the USB stick, not the HDD (you can use chroot magic to get around this). fsck showed no problems with the hard drive's EFI System Partition. (I have reported on the list how one computer I have won't boot off of the EFI System Partition if it had not been cleanly unmounted.) UEFI settings live two places: - in what we used to call the CMOS memory of the motherboard. A small chunk of persistent memory on the motherboard. - in the EFI System Partition of the HDD You need different tools to change each. I decided that the problem must be in the CMOS memory. After all, a firmware update is unlikely to change a disk. The tool I used to examine and modify the settings was efibootmgr(2). It can show, add, or modify boot entries. Warning: some of that crap is in UTF16, a perversion that is awkward to deal with. Show the boot entries. Each entry has a 4-digit number. '*' means active. $ sudo efibootmgr BootCurrent: 0001 Timeout: 1 seconds BootOrder: 0001,0000,0002 Boot0000* SATA: TOSHIBA MQ01ABD100 Boot0001* UEFI: ADATA USB Flash Drive 1.00 Boot0002* ADATA USB Flash Drive 1.00 REALLY show the boot entries. What was shown before was what a user is expected to understand. The -v also shows the part that the bootloader actually uses. If you have a Windows entry, it will likely include UTF16. This computer does not have Windows (or a Windows license). BBS seems to stand for "Bios Boot Setting", meaning old fashioned Master Boot Record style booting. $ sudo efibootmgr -v BootCurrent: 0001 Timeout: 1 seconds BootOrder: 0001,0000,0002 Boot0000* SATA: TOSHIBA MQ01ABD100 BBS(17,,0x0) Boot0001* UEFI: ADATA USB Flash Drive 1.00 PciRoot(0x0)/Pci(0x15,0x2)/Pci(0x0,0x0)/USB(1,0)/HD(1,MBR,0x2563bf1a,0x1b9d0,0x4664) Boot0002* ADATA USB Flash Drive 1.00 BBS(21,,0x0) Magic sequence to add an entry for Fedora 27. "-c" means Create an entry. "-l" means Loader: what the entry should do I accepted the default for: "-d disk" specifies the disk; default /dev/sda "-L label" specifies the user-readable description; default "linux" $ sudo efibootmgr -c -l '\EFI\FEDORA\SHIM.EFI' BootCurrent: 0001 Timeout: 1 seconds BootOrder: 0003,0001,0000,0002 Boot0000* SATA: TOSHIBA MQ01ABD100 Boot0001* UEFI: ADATA USB Flash Drive 1.00 Boot0002* ADATA USB Flash Drive 1.00 Boot0003* Linux REALLY show the boot entries. Notice the new entry has a lot of gobbledigook. I can read that but I'm glad that I didn't have to write it. $ sudo efibootmgr -v BootCurrent: 0001 Timeout: 1 seconds BootOrder: 0003,0001,0000,0002 Boot0000* SATA: TOSHIBA MQ01ABD100 BBS(17,,0x0) Boot0001* UEFI: ADATA USB Flash Drive 1.00 PciRoot(0x0)/Pci(0x15,0x2)/Pci(0x0,0x0)/USB(1,0)/HD(1,MBR,0x2563bf1a,0x1b9d0,0x4664) Boot0002* ADATA USB Flash Drive 1.00 BBS(21,,0x0) Boot0003* Linux HD(1,GPT,7ff1c66f-7d72-4295-ad96-01203c384c0b,0x800,0x64000)/File(\EFI\FEDORA\SHIM.EFI) After this, everything worked. I don't know why the firmware setup screen had no way to accomplish this (I tried a lot of settings). Reference: <http://www.rodsbooks.com/efi-bootloaders/installation.html>
