boot – How to make Ubuntu 18.04 and Visual Studios run faster?

I am new to Ubuntu Linux and just installed version 18.04 on my computer alongside Windows in dual-boot mode. However, after three weeks, Linux started to be very slow, and it will even crash a few times a day when it is not able to run my code efficiently enough. It will stop building a package completely when I run catkin build such that I am forced to switch off my laptop.

I have tried the following:

  • Looking at CPU specs with lspcu, which are good

  • Looking at the omputer make and model, gotten with the system information part of sudo dmidecode | less

  • Some of the solutions found on the following website: https://www.maketecheasier.com/linux-running-too-slow-heres-how-to-find-the-cause/. Such as: checking my CPU size (seems okay), examine CPU load with top (no process seems to be abusing my CPU usage) and check if my hard drive is overworking with iotop (it is not).

  • Examining the system with systemd-analyze blame:

            19.606s apt-daily.service
            6.913s NetworkManager-wait-online.service
            4.019s plymouth-quit-wait.service
            3.163s apt-daily-upgrade.service
            2.258s bolt.service
            1.391s snap-gnomex2d3x2d34x2d1804-66.mount
            1.354s snap-onenotex2ddesktop-13.mount
            1.352s snap-gnomex2dcalculator-826.mount
            1.337s dev-sda7.device
            1.332s snap-gnomex2dcharacters-570.mount
            1.241s snap-dub-53.mount
            1.206s snap-gtkx2dcommonx2dthemes-1514.mount
            1.172s snap-snapd-11107.mount
            1.100s snap-gnomex2dcalculator-884.mount
            1.031s snap-gnomex2dsystemx2dmonitor-148.mount
            1.013s snap-gnomex2dlogs-103.mount
             993ms snapd.service
             971ms snap-core-10958.mount
             912ms snap-code-59.mount
             911ms dev-loop4.device
             878ms dev-loop5.device
             857ms fwupd.service
             835ms dev-loop2.device
    

It seems like the upper lines are taken up a lot of time, so maybe this is a cause of the problem?

  • It should be noted that my Ubuntu running slow is mainly caused when I am using Visual Studio Code for too long – when my Ubuntu has just started, it runs fine, but after a while it gets slower and slower. I checked again with the top command the CPU usage when running a code in Visual Studio Code and it seems like maybe this causes a problem since cc1plus command runs at 99-100% CPU:

Result of top command: cc1plus running at 99-100% CPU

  • I have looked at /var/log/syslog errors as well with cat var/log/syslog | grep 'error' and the following error occurred multiple times:
Apr 16 13:48:06 jessie-HP-ZBook-Studio-G3 gnome-shell(1321): Error setting property 'Powered' on interface org.bluez.Adapter1: GDBus.Error:org.bluez.Error.Blocked: Blocked through rfkill (g-io-error-quark, 36)

Other errors that occur (not as often, though) are:

  • Finally, I went to the folder /var/crash and look for files there (ls -a), however, no files are found, the only thing my terminal displays are dots: . ..

Anyone who has any idea where to look for the cause of these crashes when running code, and if the main cause is my Ubuntu / dual boot or Visual Studio Code? I am sorry for stating such an unclear general question. If anything else is needed I’ll provide it.

How unusual would contact-printing be for a portrait studio’s commercial output?

It wasn’t at all unusual for small, local portrait studios to print using the direct contact method during the time in which Disfarmer worked from about 1915 until his death in 1959. Most small studios that concentrated on producing family portraits for the people living in the immediate area around the studio probably did not even have the needed enlarger to do the kinds of exposure manipulation – dodging, burning, unsharpen mask, etc. – that we associate with fine art techniques fully developed in the mid-20th century by photographers such as Ansel Adams, Edward Weston, and William Van Dyke in the western U.S. and by the developers at studios such as Magnum in the eastern U.S.

Another reason the use of enlargers wasn’t popular in the very early days of photography was the lack of a suitable stable light source until proper electric bulbs were invented and the electrification needed to power them had spread across the landscape. Even the sun moves in the sky fast enough that a system of mirrors to constantly adjust for that movement was needed if sunlight was used to produce enlargements on the slow reacting papers of the time. If Heber Springs, Arkansas was like most typical towns in the American South, the rural areas weren’t fully electrified until either just before or just after WWII. Since the negative sits directly over the printing paper for contact prints, the angle of the light used to expose the paper is much less critical.

Retouching certainly did go on at the time Defarmer began, but it was done directly to the negative before printing or sometimes to the finished print. Techniques including scraping with knives, drawing on top of the negative or print with graphite or ink, or even combining more than one negative either by placing one over the other or by cutting and pasting different parts of different negatives and attaching them together for making a contact print. With such techniques, contact prints from the altered negatives were still the main way prints were made.

What was unusual about Disfarmer’s technical method was his use of glass plate negatives long after pretty much the rest of the world had moved to film for the type of work he was doing: taking portraits of the local inhabitants of the area surrounding his modest studio in Heber Springs, Arkansas. Large sheet film was introduced in 1913 and rapidly replaced glass plates for large format portraits, yet Disfarmer didn’t finally switch over until near the very end of his career which lasted until his death in 1959.

When Disfarmer started around 1915, Ansel Adams was 13 years old. Willard Willard van Dyke was 9 years old and four years away from taking up photography. Weston was just beginning to make a name for himself after moving away from the large commercial studios in Los Angeles to open his own ‘Little Studio’ in Tropico, CA in 1910. He had just met Margrethe Mather, who was a major influence on Weston’s style, sometime late in 1913.

Although retouching was already being practiced (that was what Weston was doing for a living in L.A. before he struck out on his own), outside of the major commerce centers of fine art photography in places such as New York, L.A., Chicago, etc. the use of enlargers wasn’t that common.

The local portrait studios scattered in towns across the country were the “descendants” of the self-contained wagon studios that travelled the countryside in the mid to late 19th century. With wet collodion glass plates, the most common form of negative until the 1870s, the emulsion had to be mixed, spread on the glass plate, exposed, and developed within about 10 minutes. The primary skill set a potential photographer needed was the ability to quickly mix chemicals precisely and consistently each time a photo was taken so that the resulting emulsion had a predictable enough sensitivity that the exposure time would be correct.

But what has made prints of Mike Defarmer’s portraits so desirable by collectors has very little if anything to do with his use of glass plates or of direct contact prints. What makes his work desireable is the entire story of how he came to make these photos and the way he made them without trying to pose his subjects the way most portraitists at the time did. As Michael Mattis, who is most responsible for the ‘second revival” of interest in Defarmer’s portraits, said years later:

… in my view, it is this unique insider/outsider mix, so evident in the pictures themselves, that is the essence of his genius, and the reason why – despite three decades of intense searching – no other studio photographer from that era has been uncovered whose accomplishment remotely matches Disfarmer’s.

This is directly related to the entire mystique surrounding his self-instigated name change, the way he would carry his tripod around town while riding his horse wearing a Zorro-like cape (at a time when most people had long since moved from horseback to automobiles for personal transportation), and the way he would take the photo without warning his subjects or allowing them to pose first. It was probably also related to the fact that he was a bachelor, loner, atheist, and photographer in a small rural Arkansas town that had no other photographers, no other (publically acknowledged) atheists, and probably very few bachelors or anyone else that took being an eccentric loner to such extremes.

In an interview for the local newspaper (who printed it in the “Stranger than Fiction” section!) about why he changed his last name from Meyer to Disfarmer, he claimed that he was delivered to his parent’s doorstep by a tornado. He also made it very clear that he changed his name because his surname at birth, Meyer/Meier/Meijer, was German for “dairy farmer” and he didn’t want to be a farmer or associated with farming in any way. This he said in a small town in which just about everyone, including Disfarmer, made their living farming or by providing goods and services to farmers and their families!

Some of his clients described the experience of being photographed by Disfarmer as “very spooky and scary”. He would disappear under the hood of his camera for long lengths of time and then suddenly take the photo without warning. “Instead of telling you to smile he just took the picture. No cheese or anything.”

applications – I’m facing issue in Android studios, my emulator process isn’t working

My codings are correct it’s just as soon as I run my app it finishes gradle build but after that message pops up showing error while waiting for device:the emulator process for avd was killed

I intalled latest version already made new app in avd so that it can create but it isn’t happening do you have any solutions?

Los Angeles – I bought two Universal Studios Hollywood tickets for two, but both tickets have my name on them

I am currently in the US and Canada for a few weeks and will also stop by in LA. My travel partner and I decided to visit Universal Studios and buy tickets through an online platform (Klook if someone is curious).

When I received the tickets, I found that my name was on both tickets (I made the payment). This was not a problem for me as both tickets are valid. However, I found the following in the "Important Instructions and Terms of Use" section of the ticket:

This ticket is only valid for the person named there.

Would it be a problem if I used the two tickets for myself and my partner? I don't hope the tickets are non-refundable and I paid a lot of money for it, but hopefully someone can shed some light on this issue.

Thank you very much.

TO EDIT

I also just noticed that the ticket says:

Valid for one (1) guest entry and one (1) Universal Express ticket to Universal Studios Hollywood.

Does that mean I could only buy a ticket and take my partner with me?

Sorry for the mess of questions, I'm just very confused by the language.
