OpenVZ / Virtuozzo 7 First Impressions
Jul. 1st, 2015 at 4:34 PM
openvz dowdle
Odin and the OpenVZ Project announced the beta release of a new version of Virtuozzo today. This is also the next version of OpenVZ as the two are merging closer together.
There will eventually be two distinct versions... a free version and a commercial version. So far as I can tell they currently call it Virtuozzo 7 but in a comparison wiki page they use the column names Virtuozzo 7 OpenVZ (V7O) and Virtuozzo 7 Commercial (V7C). The original OpenVZ, which is still considered the stable OpenVZ release at this time based on the EL6-based OpenVZ kernel, appears to be called OpenVZ Legacy.
Odin had previously released the source code to a number of the Virtuozzo tools and followed that up with the release of spec-like source files used by Virtuozzo's vztt OS Template build system. The plan is to migrate away from the OpenVZ specific tools (like vzctl, vzlist, vzquota, and vzmigrate) to the Virtuozzo specific tools although there will probably be some overlap for a while.
The release includes source code, binary packages and a bare-metal distro installer DVD iso.
Bare Metal Installer
I got a chance to check out the bare-metal installer today inside of a KVM virtual machine. I must admit that I'm not very familiar with previous Virtuozzo releases but I am a semi-expert when it comes to OpenVZ. Getting used to the new system is taking some effort but will all be for the better.
I didn't make any screenshots yet of the installer... I may do that later... but it is very similar to that of RHEL7 (and clones) because it is built by and based on CloudLinux... which is based on EL7.
CloudLinux Confusion
What is CloudLinux? CloudLinux is a company that makes a commercial multi-tenant hosting product... that appears to provide container (or container-like) isolation as well as Apache and PHP enhancements specifically for multi-tenant hosting needs. CloudLinux also offers KernelCare-based reboot-less kernel updates. CloudLinux's is definitely independent from Odin and the CloudLinux products are in no way related to Virtuozzo. Odin and CloudLinux are partners however.
Why is the distro based on CloudLinux and does one need a CloudLinux subscription to use it? Well it turns out that Odin really didn't want to put forth all of the effort and time required to produce a completely new EL7-clone. CloudLinux is already an expert at that... so Odin partnered with CloudLinux to produce a EL7-based distro for Virtuozzo 7. While CloudLinux built it and (I think) there are a few underlying CloudLinux packages, everything included is FOSS (Free and Open Source Software). It DOES NOT and WILL NOT require a CloudLinux subscription to use... because it is not related to CloudLinux's product line nor does it contain any of the CloudLinux product features.
The confusion was increased when I did a yum update post-install and if failed with a yum repo error asking me to register with CloudLinux. Turns out that is a bug in this initial release and registration is NOT needed. There is a manual fix of editing a repo file in /etc/yum.repos.ed/) and replacing the incorrect base and updates URLs with a working ones. This and and other bugs that are sure to crop up will be addressed in future iso builds which are currently slated for weekly release... as well as daily package builds and updates available via yum.
More Questions, Some Answers
So this is the first effort to merge Virtuozzo and OpenVZ together... and again... me being very Virtuozzo ignorant... there is a lot to learn. How does the new system differ from OpenVZ? What are the new features coming from Virtuozzo? I don't know if I can answer every conceivable question but I was able to publicly chat with Odin's sergeyb in the #openvz IRC channel on the Freenode IRC network. I also emailed the CloudLinux folks and got a reply back. Here's what I've been able to figure out so far.
Why CloudLinux? - I mentioned that already above, but Odin didn't want to engineer their own EL7 clone so they got CloudLinux to do it for them and it was built specifically for Virtuozzo and not related to any of the CloudLinux products... and you do not need a subscription from Odin nor CloudLinux to use it.
What virtualization does it support? - Previous Virtuozzo products supported not only containers but a proprietary virtual machine hypervisor made by Odin/Parallels. In Virtuozzo 7 (both OpenVZ and Commercial so far as I can tell) the proprietary hypervisor has been replaced with the Linux kernel built-in one... KVM. See: https://openvz.org/QEMU
How about libvirt support? - Anyone familiar with EL7's default libvirtd setup for KVM will be happy to know that it is maintained. libvirtd is running by default and the network interfaces you'd expect to be there, are. virsh and virt-manager should work as expected for KVM.
Odin has been doing some libvirt development and supposedly both virsh and virt-manager should work with VZ7 containers. They are working with upstream. libvirt has supposedly supported OpenVZ for some time but there weren't any client applications that supported OpenVZ. That is changing. See: https://openvz.org/LibVirt
Command line tools? - OpenVZ's vzctl is there as is Virtuozzo's prlctl.
How about GUIs or web-based management tools? - That seems to be unclear at this time. I believe V7C will offer web-based management but I'm not sure about V7O. As mentioned in the previous question, virt-manager... which is a GUI management tool... should be usable for both containers and KVM VMs. virsh / virt-manager VZ7 container support remains to be seen but it is definitely on the roadmap.
Any other new features? - Supposedly VZ7 has a fourth-generation resource management system that I don't know much about yet. Other than the most obvious stuff (EL7-based kernel, KVM, libvirt support, Virtuozzo tools, etc), I haven't had time to absorb much yet so unfortunately I can't speak to many of the new features. I'm sure there are tons.
About OS Templates
I created a CentOS 6 container on the new system... and rather than downloading a pre-created OS Template that is a big .tar.gz file (as with OpenVZ Legacy) it downloaded individual rpm packages. It appears to build OS Templates on demand from current packages on-demand BUT it uses a caching system whereby it will hold on to previously downloaded packages in a cache directory somewhere under /vz/template/. If the desired OS Template doesn't exist already in /vz/template/cache/ the required packages are downloaded, a temporary ploop image made, the packages installed, and then the ploop disk image is compressed and added to /vz/template/cache as a pre-created OS Template. So the end result for my CentOS 6 container created /vz/template/cache/centos-6-x86_64.plain.ploopv2.tar.lz4. I manually downloaded an OpenVZ Legacy OS Template and placed it in /vz/template/cache but it was ignored so at this time, I do not think they are compatible / usable.
The only OS Template available at time of writing was CentOS 6 but I assume they'll eventually have all of the various Linux distros available as in the past... both rpm and deb based ones. We'll just have to wait and see.
As previously mentioned, Odin has already released the source code to vztt (Virtuozzo's OS Template build system) as well as some source files for CentOS, Debian and Ubuntu template creation. They have also admitted that coming from closed source, vztt is a bit over-complicated and not easy-to-use. They plan on changing that ASAP but help from the community would definitely be appreciated.
How about KVM VMs?
I'm currently on vacation and only have access to a laptop running Fedora 22... that I'm typing this from... and didn't want to nuke it... so I installed the bare-metal distro inside of a KVM virtual machine. I didn't really want to try nested KVM. That would definitely not have been a legitimate test of the new system... but I expect libvirtd, virsh, and virt-manager to work and behave as expected.
Despite the lack of perfection in this initial release Virtuozzo 7 shows a lot of promise. While it is a bit jarring coming from OpenVZ Legacy... with all of the changes... the new features... especially KVM... really show promise and I'll be watching all of the updates as they happen. There certainly is a lot of work left to do but this is definitely a good start.
I'd love to hear from other users to find out what experiences they have. If I've made any mistakes in my analysis, please correct me immediately.
Congrats Odin and OpenVZ! I only wish I had a glass of champagne and could offer up a respectable toast... and that there were others around me to clank glasses with. :)

Does that mean VZ7 will only be available as a complete distribution and (kernel) packages for RHEL/Debian won't be provided anymore?

take a look to wiki page about installation methods - https://openvz.org/Quick_installation
All RPM packages are available in yum repo - http://download.openvz.org/virtuozzo/releases/7.0/x86_64/
Scott, thanks for a detailed review and for addressing some questions we haven't addressed in our release FAQ.
> Any other new features?
One pretty big feature is a switch from in-kernel ckeckpoint/restore implementation (i.e. vzcpt/vzrst kernel modules) to CRIU (http://criu.org). This is a good change as CRIU is very dynamic project of us and hopefully it will help to solve some issues people have with live migration.
[While talking about CRIU, last DockerCon 2015 session (a wrap-up) showed three demos: Docker on Raspberry Pi, Docker on IBM Z mainframe, and Quake server live migration using CRIU. Although me myself was showing something like this about 8 years ago, I was still very impressed.]
> vztt
Here is an insider story (I am more and more into history as I'm getting older). I was working on new template mgmt tools (i.e. vztt/vzpkg prototype) in 2004, then left the company in some frustration as no one was interested. I came back in 2005 to do OpenVZ revolution, and I dusted off my prototype and released it as vzpkg for OpenVZ (although I already hated working on it, as I spent so much time on it without it getting anywhere in 2004). Next thing, commercial customers asked why OpenVZ has better template tools than VZ, and other guys started working on that.
So, this vztt you see is essentially a grandchild of OpenVZ's vzpkg (with added DEB support, multiple versions of RPMS (the thing that made me stop working on it as it's very cumbersome), and other bells and whistles).

Maybe you can come for LinuxCon/ContainerCon/Linux Plumbers in Seattle this August and we'll definitely do that!

Sorry, this currently doesn't describe anything, really.
The idea, in a nutshell, to build upon VSwap, adding a userspace daemon (VCMMD) which will observe resource usage and node health and dynamically change limits using some kind of heuristics. This is all I can tell right now; we will ask developers to give a better overview at that wiki page.

Remembering The Victims of the Drug War
Tungkol sa Website
Alexander Dimalanta
Occupation: tricycle driver
Incident Details
Date of Incident: June 14, 2018
City of Incident: Manila
Province of Incident: Metro Manila
Killed in police operation in public
http://newsinfo.inquirer.net/1001480/death-in-drug-war-aborts-a-fathers-day-date-for-4-kids
In a small multipurpose hall in Sta. Cruz, Manila, where the shanties and houses rattle every now and then as trains pass through the neighborhood, Alexander Dimalanta's family mourns his death so close to Fathers' Day.
On June 14, the 25-year-old tricycle driver was shot dead inside the Manila North Cemetery after allegedly shooting it out with police officers during a drug buy-bust operation.
Dimalanta left behind a widow and their four young children, who remember him as a loving dad.
"I still don't know how to even begin, let alone explain to them, that their father is gone," Dimalanta's partner, Michelle, 25, said. "To be orphaned so close to Father's Day seems like the cruelest kind of tragedy."
Dimalanta is among the latest victims in the Duterte administration's bloody war on drugs which rages in poor communities like the back alleys of Sta. Cruz.
It has killed mostly male breadwinners, leaving behind what its critics call "a nation of widows and orphans."
No drug involvement
Police reports said Dimalanta shot at PO1 Evan Repil of the Sta. Cruz police station three times but missed, prompting the officers to fire back.
Felled by several bullets to the chest, he was rushed to the nearby Chinese General Hospital but died from his wounds.
Police said Dimalanta was a notorious drug peddler—a claim his grief-stricken family condemned as an "unbelievable lie."
Michelle insisted that her partner was a loving husband and a doting dad.
"Even if we were neck-deep in debt he could never have done that, not ever," she said. "I swear on my children, even if you cut his corpse open and test him for drugs."
Twisting narrative
Barangay officials said Dimalanta had no previous criminal record.
Dimalanta was "kindhearted and generous," swore his younger sister Vina.
On the day he died, she said, he even volunteered to help out fellow tricycle driver Marvin Rosario convey two female passengers.
Cemetery residents told a story different from the official police account.
They said two female strangers alighted at the far end of 2nd Street and then inexplicably walked back to where they came from.
Police officers in civilian clothes suddenly appeared and hauled two men to the edge of the cemetery.
One of the residents said he saw Dimalanta being forced into a narrow alley between tombs. "The police warned us to leave, so we ran like hell. We all heard at least 12 gunshots," he said.
Police then hailed a passing tricycle to rush Dimalanta's body to the hospital.
Rosario was also arrested and later detained at the Sta. Cruz station. But the spot report on his arrest did not say he was with Dimalanta during the shooting.
Instead, it said Rosario was arrested at 2 a.m. on June 15 at the cemetery for gambling and drug possession.
The Inquirer tried to reach out to the station commander, Supt. Julius Domingo, but was told he was out.
Humble, kindhearted
Because he only finished grade school, Dimalanta had been a tricycle driver for most of his life, Michelle said.
His parents separated and left with their new partners when he was still young, so he had to look after his two sisters.
Dimalanta's four children — aged 5, 4, 2 and 10 months — all had asthma.
Michelle said he was also nursing a kidney ailment but spent his meager income on diapers and food.
"He was the type to skip meals and drive twice as long just to earn a little extra," Dimalanta's elder sister Joan said.
Underneath the hard work, however, was a breadwinner's desperation and exhaustion, embodied in a brief note Dimalanta wrote on his cell phone two days before he died.
It read: "Lord, please help me. I don't know what else to do. I can't take it seeing my family suffer. I love them very much but I can't do much more … I don't wish to do evil."
"It was so hard for him but he never wanted us to worry," Michelle said. "Day after day, we both struggled to make ends meet … How can we now survive without him?"
No celebration
Dimalanta's death cut short his promise to take his family out for a meal to celebrate Father's Day, Michelle said.
They were supposed to go to Mass at Quiapo Church on Sunday to thank the Lord for healing the kids, who were all stricken with chicken pox last month.
"It's his birthday," his eldest daughter Alexa said, or so she thought. "We were going to eat out. I even have a gift for him, but it's a secret."
Her father is "dead," she said, although she does not know what it means. "Mama said he won't be back. But last night he told me to eat first."
She misses her dad, something that Michelle knows she would have to reckon with when they bury him.
"It's only going to get harder from now on," Michelle said. "But we're determined to fight. We're sure Alex can't rest until we bring him justice."

Today Elliott spent some time working in the yard with my Dad. Grandpa was teaching Elliott about using tools correctly and safely.
They were cleaning up the yard. Spring cleaning if you will.
Elliott was using the loppers to cut up brush. My Dad had asked him to cut them up into 6 inch pieces so they would fit in the bag.
When I arrived to pick him up, I couldn't get Elliott to leave. He was so focused on helping Grandpa finish up that I had to practically drag him out of there. He was so proud of himself for being able to use tools and help Grandpa out.
This type of real life experience is so important, especially for kids on the Autism spectrum because these are life skills that they don't learn in school.
My kids absolutely love to learn things like this. They love to help out on projects around the house. It's important to me that I help prepare them for life and teach them everything I can, while I can.

Cons: "Alaska needs to work more with their terminals to make sure their customers are getting what they need. JFK does not have TSA precheck or priority boarding, but Alaska does not tell you that beforehand. That's important!! Alaska gave me a lot of attitude about changing my flight, so I couldn't."
Cons: "4 hours late"
Pros: "Accommodation and sevice was good."
Pros: "Nice in flight entertainment options. Good movie selection."
Cons: "I remember watching the show "Band in Seattle" in previous Alaska flights (with the Gogo app), but I guess this was an ex Virgin airplane, and it didn't have that show. There was good movies though."

Cons: "Sat on runway for hour after plane landed, just waiting for a gate. How is this even possible? With no offer of beverages or food. Or updates. Crew was hardly seen maybe once or twice on a six hour flight. When asked to take trash, they would reply, we are only doing drinks at the moment."
Pros: "The flight was fine and comfortable"
Cons: "I just did not like that we were on flight for 6 hours and no food was given complimentary plus there was no vegetarian food at all to eat as we don't eat meat at all"
Cons: "We sat onboard for two hours not being told at first what the holdup was. We were then told there was an issue getting a motorized wheelchair stored in cargo. The only indication about the delay was this. If a customer is traveling with this need I would presume the airline knows in advance so why was it a problem and a surprise which delayed a plane full of people for two hours. People missed connections etc. Not good! And barely any updates"
Pros: "Seats are comfortable, crews are all approachable and helpful."

Cons: "It left 3 hours late . No free email or Facebook"
Pros: "No free WiFi, no hand soap in the restroom, my chair would not recline, no free snacks thank god for the free water and coffee, $9 cheese plate half of which was inedible, no power outlets or usb charging ports. And the flight attendants were so rude, a simple question was met with short, hostile replies and rhetorical questions instead of friendly respnoses. I WILL NEVER FLY ALASKA AIR AGAIN."
Cons: "No free WiFi, no hand soap in the restroom, my chair would not recline, no free snacks thank god for the free water and coffee, $9 cheese plate half of which was inedible, no power outlets or usb charging ports. And the flight attendants were so rude, a simple question was met with short, hostile replies and rhetorical questions instead of friendly respnoses. I WILL NEVER FLY ALASKA AIR AGAIN."
Pros: "The crew was great, and the free movie selection was outstanding. Because the flight was full, they let me check my carry-on bag for free."
Cons: "They ran out of the meal I would have ordered."
Pros: "Customer service excellent"

Pros: "The staff was helpful and professional at every juncture - from check in to landing. The flight was smooth and landed a bit early. Tv/movie choices were great."
Cons: "Airplanes are so cramped, it's ridiculous. I'm only 5'2" and I didn't even have the room to bend down to reach under the seat to pick up a pen I dropped. Take out a row and give everyone more room."
Pros: "They were very hospitable and humorous"
Pros: "Danielle the woman who was handling everyone complaining at the gate. She was the only person helping anyone with whatever she could. Also the crew, weren't properly stocked with anything, not even water. They did their best to work with the lack of supplies and information they were given. Otherwise I felt like I was in a bad version of the twilight zone. And I love that show."
Cons: "Absolutely everything except for the crew listed above. The delay was never informed to anyone until check in- even then the gate's LCD screen wasn't even updated with a delay. They said they had to call British airlines to ask them to change the information! No one was allowed into the lounge for a 5 hour delay which is horrible. Considering the airport was under construction and the restaurants all closed an hour before boarding. It was horrible. I missed work because of this and my day rate is 800$ and all I got was a lousy $100 voucher. If Alaska airlines had, I don't know let everyone into the lounge and provided us with more respect and something in return maybe it would be so bad. But right up to three of the boarding crew (not Danielle) who were YELLING at people. People who were tired and confused. It was the worst experience and I am a global flyer with my company."
Pros: "They made good time getting us home to Seattle before the estimated landing time."
Cons: "The plane didn't have device charging ports like some do."
Cons: "the person nwxt to me was hesitant to stand ip when I wanted to go bathroom. Ither than that I lived it. Attendants were super nice which makes experience different."
Pros: "Awesome customer service at all times throughout the flight"
Cons: "Late departure, no headphones on board (thus no access to movies etc), and while waiting at gate to depart, plane became very hot with no airflow, Electronic ordering system for drinks also was not working And it's absurd that a 6.5 hour flight has no snacks or food offered. Cheap Branson."
Pros: "More leg room"
Cons: "Snack for 5 hrs flight is not too much"
Cons: "No free snacks anymore, that's a bummer."
Cons: "Screaming baby. And it took forever to board the plane."
Pros: "Although the departure was delayed because of regulations for the flight crew, they made up the time and got us to Lortland only 15 minutes later than originally planned! Flight crew was friendly and fabulous!"
Pros: "The food order concept"
Cons: "No food, not even snacks, despite the long fligjt"
Pros: "My chair was broken the entire plane and there was no where to move me to. I was uncomfortable the entire flight"
Cons: "Update your planes"
Cons: "Chair was not working could not adjust Media entertainment system was not working at all. We were told these items had been broken for over two weeks. Makes you wonder about the mechanics of the rest of the airplane"
Pros: "Efficient boarding, reasonable space in cabin and overhead bins"
Cons: "JetBlue is awful. TVs don't work. Staff isn't friendly"
Pros: "The crew was accommodating"
Cons: "The TV did not work…"
Pros: "Crew was courteous and gave constant updates in regards to any delays."
Cons: "Flight was delayed and there was congestion prior to take off. Not sure there was anything that could've been done."
Pros: "Crew is always great."
Cons: "The TV wasn't working at my seat"
Pros: "The crew was ok."

Pros: "Yes"
Cons: "Boarding pass on phone text"
Cons: "Awful treatment of passengers."
Pros: "The inflight crew was absolutely incredible. They were funny and helpful especially as our situation was incredibly bad."
Cons: "After waiting almost an extra hour plus for a delay, the boarding process was complete chaos. Not to the fault of the crew at LaGuardia, but just based on the annoyance and impatience of the passengers waiting to board. Once on the plane, our row was the only one with broken TVs. Unfortunately for my husband and myself, we were flying with two toddlers with whom we had solely expected to entertain with the TV."
Pros: "The personnel were courteous and listen to your request ,the flight was exceptional.."
Cons: "No comments at this time."
Pros: "Leg room and tv"
Cons: "Increased cost of luggage, snacks , and perhaps a little more info about the flight delay"
Pros: "The flight was on time. Fly-fi was available"
Cons: "Tv/ entertainment system was flickering intermittently"
Pros: "Great service. Also loved the size of the seats and the leg room that I had."
Pros: "On time flight, roomier seat"
Cons: "Airport, IGA"
Pros: "Free unlimited snacks! Lots of leg room"
Cons: "No safety video. Airport terminal was very small and stuffy. Security line was long"
Pros: "Boarding was a bit delayed in the beginning but back on time very quickly, seat comfort and legroom was great. Loved that I got a full sized can of soda, that's always fantastic and snacks were fine."
Cons: "My Seat 23D had a defective TV, so it was flashing on and off constantly throughout the whole flight, usually I don't have an issue with the entertainment because I like to sleep during flights, but due to some turbulence I was awake for part of the flight. Unfortunately with the flashing TV it gave me pretty bad nausea to the point of wanting to vomit, this is the first time I've experienced anything like this on a plane, was definitely looking forward to landing so I didn't have this nauseating feeling anymore. I have a video of the issue if anyone at Jetblue was interested in seeing. It was flight 499 from LGA to Orlando on 9-16-18. Thanks."
Pros: "Great flight with early departure; not crowded"
Cons: "Longer flight than normal due to Florence"
Cons: "delays, crying children and sniffling sneezing passengers. Restroom was dirty."
Cons: "Delays, changed departure gates. Getting used to this on most airlines these days. Was hoping JetBlue"
Pros: "Crew was very friendly and helpful. This was my first flight on JetBlue and I was impressed with the selection of snacks and drinks."
Pros: "Efficient and kept us informed despite weather delay. Lovely flight attendants"
Cons: "Non Working tv, cramped seats"
Cons: "The airline had the flight delayed due to waiting for flight attendants. Very irresponsible of the crew and members, which weren't working on the flight"
Cons: "Flight was already delayed and then we sat on the airplane for approximately 45 minutes before take off."
Pros: "Friendly crew and fast flight."
Cons: "No reclining seats"

Cons: "I was left at a gate and wasn't informed of the gate change. I was in a wheelchair and needed assistance. I was left and almost missed my flight. I arrived at the gate with 15 minutes before takeoff. The agent was very rude...she said my seat had been given away. After checking she was wrong."
Cons: "No AC for an hour before takeoff - very uncomfortable. Audio for tv did not work."
Cons: "Flight was delayed a bit due to a couple passenger booking/misc issues. 1st class didn't get gate bevfood service. Oven was busted so my meal wasn't available.

Cons: "Passengers who pay retail for first class on domestic flights should get access to the Delta lounges even without the AE card. Other airlines do this, and we have come to expect it."
Pros: "The boarding was fast and very well handled."
Cons: "My flight from Chicago was two hours late and that's why I missed the flight from Atlanta to Buenos Aires. No one helped and did not know that the flight was delayed and I had to find a place to sleep. I'm not satisfied with the experience and I have not yet arrived in Argentina because of the whole"

Pros: "It was a normal flight as well expected."

Pros: "My flight was great. Boarding was easy and the seats were comfortable."
Pros: "The service was amazing , the staff was honestly friendly and nice"
Pros: "Great service, nice agent friendly"
Cons: "I was unable to fly at all due to a spelling error on my ticket. The airline refused to alter the ticket. Worst experience of my life, ruined my Christmas"
Pros: "Very nice flight and attentive staff. Enjoyed the view of NYC as we flew up the East River, then looped over Nassau County to approach LGA."
Cons: "The male flight attendant who handed out the complimentary drinks and snacks acted a bit strangely. I was very thirsty, and I asked him if I could keep the rest of the can of soda. He neither said yes nor no, but rather completely ignored what I said and just poured my drink and moved on. I was a mildly annoyed, but figured maybe it was policy and he was shy and didn't want to debate the matter. When he took care of the older couple behind us, however, things got really strange. He asked them whether they wanted pretzels or peanuts, but they misheard him and asked for a ginger ale. I happened to know that he did have ginger ale, since my wife had just gotten one, but rather than just pouring the old folks a drink, he repeated himself. "Peanuts or pretzels?" They misheard again and asked him whether he had a diet ginger ale. Again, rather than just pour them the drink, he repeated himself. "Peanuts or pretzels?" This went round and round a few more times -- like a poorly designed computer UI that refuses to accept anything except the correct input -- before the old couple finally figured out the disconnect and picked their snacks before their drinks. Very weird."
Cons: "Cancelled my flight because I lost one of the arms"
Cons: "Layover"
Pros: "Short flight"
Cons: "Too cold Not friendly boarding agent"
Cons: "2.5 hour delay for no apparent reason at first (supposed mechanical issues with plane) and then waited on plane at gate for a missing pilot who never got picked up from his airport and got stuck in Chicago traffic trying to get to O'Hare. Eventually had to take pilot from another flight before leaving at 8:45 when flight was scheduled for 6:00am."
Cons: "Had a death in the family and no one would help me get back home"
Pros: "Seats were comfortable. Snacks!!! Nice flight crew."
Cons: "I liked everything."
Pros: "The Gogo Inflight wifi and entertainment did not work for even a minute. I choose flights based on their amenities and this one had offered full WIFI service which swayed me to choose to fly with Delta. I'm not sure who is to blame about this issue but I'm pretty frustrated that it was completely dysfunctional."
Pros: "The movie I watched was pleasant, although I had trouble hearing it because of the situation described below."
Cons: "There was a family seated behind us with several crying, loud children. We were miserable. Even my headphones with a Mozart sonata cranked up to loud did little to mask the noise. Probably not Dela'a fault, but the crew did nothing to mitigate the problem."
Cons: "Plane was sat broken at gate and needed part to be flown in. 150 minutes delayed. Not acceptable."
No foot service or entertainment. Just a Trip from one place to the other. Not much different that a bus ride except it is faster and more expensive.
Cons: "Late and then mechanical issues."
Pros: "Crew was great"
Cons: "Seat was uncomfortable. Flight was much too crowded"
Pros: "Flight was cancelled after multiple delays & I changed to United."
Cons: "Stop delaying & canceling flights, especially last minute"
Pros: "Really easy boarding and flight. Great in flight entertainment options."
Pros: "All was good"
Cons: "Nothing to complain about."
Pros: "Seat assignment process was great and considerate of my preferences."
Cons: "If AA could fix its luggage handling process that would be great. BOTH (!) of my bags have been lost on this flight. Both have been eventually located, recovered and delivered to me, but experience was not pleasant this time."
Pros: "Flight attendants were friendly and thoughtful."
Cons: "Seating is too tight. Hard to believe that in 2019, major airlines still have seats without any electrical or UBS outlets for charging devices."
Cons: "Plane was about 1000 years old and I don't think I've sat in a more uncomfortable seat."
Pros: "Comfortable seats and snack / drinks service"
Cons: "Delayed flight departure and bumpy landing"
Cons: "I was apparently "flagged" by British Airways for extra security checks. As I understood it in London, I was randomly selected for this security check. This then apparently meant that I was to be flagged for all subsequent flights. This meant that in Chicago, after going through two other security checks that day (Zurich and London) and completing customs, I had to engage in a full Homeland security check. This involved removing protective covers from my laptop and phone that were hard to get off (not meant to be taken off regularly) and a full body search that I did not have to do in London. After many hours of traveling, this was very a frustrating experience."
Cons: "I will never, ever book with Kayak again"
Pros: "Flight crew was great. The plane was half full, so the attendants allowed us to move."
Cons: "Terrible landing in Charlotte. The plane was rattling and had an annoying whistle."
Cons: "British Airways/American Airlines lost/delayed luggage again! Then send an email in the middle of night with a link to schedule home delivery of the luggage that was valid for 4 hours only. It is clearly an attempt to cheat out of their responsibility of home delivery of the luggage that was delayed the second time. Poor, poor service by American Airlines."
Cons: "It was not clear that I needed a different 6 letter code to checkin using the AA website. I finally got frustrated and called AA only to find out the code was different. The codes should have been the same or you should have referenced it on the website when I tried to check in"
Cons: "Flight was delayed for more than 4 hours with little communication from staff as to why, gate was changed to a gate across the airport."
Pros: "The boarding was quick and easy as well as the crew was friendly and accommodating. Great end to a fun weekend away."
Pros: "Our plane was late getting to the gate. They kept us informed and turned it around pretty quickly. There were storms between Chicago and Rochester so we were rerouted. As a result the hour flight was an hour and a half. The pilot kept us informed and it was a very smooth flight. So even though I was over an hour late arriving I so appreciated the communications and the safer route. AA seems to be communicating more than other airlines and I appreciate that. Flying is absolutely no fun anymore so you take what you can get for the positives."
Cons: "WiFi wasn't working so I couldn't communicate my late arrival to family picking me up."
Cons: "On my first flight from SLC to ORD I asked 3 different American Airlines employees if I needed to pay for my carryon before I got on the plane. They all said no. I got on the plane, put my carryon under the seat in front of me and everything was great. I landed in Chicago, got to my gate, went to board and this very rude employee stopped me after I scanned my ticket and told me I couldn't board with my bag. The EXACT bag I had boarded with in SLC. After harshly grabbing my bag and putting it in the carryon basket to check for size, she wouldn't let me pass by her into the boarding bridge and told me I was going to have to pay. I tried explaining that I had asked I'm SLC if I needed to check it and they had all said no and that it fit under my seat. She said, "I don't care what they said in SL, this is what I'm saying here." And directed me to the front desk where I had to pay $50!! $50 for a carryon backpack that fit under my seat comfortably 20 minutes before!! Without saying a word (cause I didn't want to yell at the poor girl behind the desk) I paid the $50 and proceeded to enter the bridge but before I passed through, the rude woman said, "have a nice flight ma'am" and scoffed!! An audible scoff. So I'm short, I hate American Airlines and I will do my BEST to not have to fly with them in the future."
Pros: "The fact that they re-booked without me having to contact customer service."
Cons: "The connecting flight was cancelled while boarding was in progress at the start of the journey."
Cons: "Flight was delayed by untold circumstances causing us to miss our connecting flight to Venice."
Pros: "On time departure and early arrival"
Pros: "Nice crew Spacious plane"
Pros: "The crew was amazing, flight was very smooth, arrived early, plane clean, service was great."
Cons: "For being in first class, my seat did not recline so I couldn't sleep and audio for my entertainment center was not working"
Pros: "Good time for flight"
Cons: "Tight, hot inside plane, no refreshments"
Cons: "They left the lights on the whole flight"
Pros: "They alerted me to problems with our flight and we switched to an earlier flight. No problems with new flight. Good service."
Cons: "Great trip"
Pros: "Not turbulence"
Pros: "Was on time."
Cons: "Not eventful."
Pros: "crew was great, plane seemed newer and clean. individual screens worked better than others I've used in flights."
Cons: "newer touch screens were great except viewing angle couldn't be adjusted. standard food was horrible, esp for an international flight; not sure if specialty diets have better meals. kid movies were dubbed into many language options but Chinese was not one for ANY kid films. bathrooms with the same crappy mini sinks that you can't really wash your hands in, esp if someone pukes in it. they should all learn from Japan's ANA airliners with the motion sensor sinks with faucets raised up high enough for you to wash your hands without touching the gross basin."
Pros: "On time, good service."
Cons: "Luggage did not make the transfer on time (Chicago-Charlotte after Tokyo), although they had about 45 minutes to load it. Do not buy an international ticket with less than 1.5 hours transfer time. (It took 45 minutes to get through customs/immigration and retrieve luggage for transfer."
Cons: "Missed it."
Cons: "An S80? Really? This plane was older than me! Horrible plane! The crew looked like they had been up since 4 am. Looked exhausted and unfriendly. I do want to clarify that this was an American Airlines operated plane, not etihad."
Cons: "The cramped space"
Cons: "All was excellent! Only the internet was not working good , payed for all flight access but most of the time the internet was not working. Anyway I contacted support team and they refunded me"
Cons: "The flight was delayed more times than I can count, we got a different reason each time. Weather I can understand, but telling us we are waiting on a specific crew to arrive and then announcing that crew is not for our flight was just terrible communication. No one seemed apologetic. The only thing they did was bring a snack cart over for us, and that got raided by children so many people didn't get anything. We had arranged transport from Orlando to Tampa for that evening, and our rides had to cancel because instead of 7pm we were now arriving at 130am. Your airline's mistakes put everyone at an inconvenience and we weren't offered assistance to fix it. My husband went to ask for help in arranging new transport home, but he couldn't even get to the front of the line. The customer service was terrible. We really enjoyed our first leg of the flight home with American Airlines, but after the second leg and all of the problems we had... we will not fly with American Airlines in the future."
Cons: "very cold"
Cons: "This made the check in process extremely frustrating and confusing. Traveling with my elderly dad who had to squeeze between two large men for 7 hours because people who actually booked the airline got priority seating. We had to pay an extra $500 to upgrade to comfortable seats. Not pleased w Kayak."
Pros: "The crew was great and getting 2 meals was very nice."
Cons: "My headphone jack kept malfunctioning (loud popping noises in my earbuds) while watching the movie and all the reading lights came on and stayed on the majority of the flight so sleeping was difficult."
Pros: "An agent found me a window seat for the Chicago-Barcelona leg of the trip with extra leg room. That was amazing. Also, the lost luggage assistant for American Airlines was super helpful and nice. Also, the 787 (I think that was the Chicago-Barcelona craft) was a very enjoyable airplane. It was super smooth. It had high tech windows that adjusted the amount or type of light that could filter through the windows depending on the settings."
Cons: "When I arrived in Barcelona my Bag went missing. It showed up an two hours after my flight landed."
Pros: "I enjoyed the entertainment because I don't watch movies in the theater often. The movies I saw in-flight were recent films I've been wanting to see and made time pass fairly quickly."
Cons: "I'm not a giant, but there definitely was not enough leg room in the main cabin. I could not sit comfortably, especially in the middle seat."
Pros: "Food on time. Good Food. Good Entertainment like watching movies. Top priority for Diabetes or any other patients."
Cons: "Little guidelines for new comers especially while changing the flights."
Pros: "Good flight. Arrived on time"
Cons: "Jet bridge was broken and needed repair. Delayed departure."
Pros: "The crew were exceptionally friendly and helpful. They made the negatives about the flight much more bearably be their excellence service whether during boarding, in flight, or after landing."
Cons: "I booked the flight originally through british airways and expected your standard, modern plane for cross atlantic travel. Boarding to find myself on a 767 designed (and likely built) in the 80s was rather disappointing."
Pros: "Pilot info/smooth flight."
Pros: "Seats were really neither notably comfortable nor notably uncomfortable. I think they were slightly on the comfortable side."
Cons: "Would be nice to have more modern aircraft amenities, like power outlets for device charging, and display screens with at least some complimentary entertainment, or at least flight path tracking. Boarding counter lady was obnoxiously strict about not letting our carry-on bags to be carry-on. She made us test them in the size device and said they were too big, even though they could easy be pushed into the space, and regardless of the fact that we just flew on an American Airlines flight with them as carry-on and were only on a layover with them! Regarding the previous AA agent who let them be carry-on, she said "shame on them." Complete opposite of the positive experience we had with her counterpart in Phoenix. ಠ_ಠ"
Cons: "They cancelled the flight and put me to fly the next day"
Pros: "Everybody was nice my ride was comfortable and they treat me with respect"
Cons: "I like everything"
Cons: "They left on time with 46 pax and took over a 2 hour delay. Then my bag did not show up."
Cons: "Website is still slow to update trip delays, not a problem today though!"
Pros: "The crew was super nice and helpful. They made an effort to answer any questions the passengers had. They made the flight home very enjoyable. I plan to fly with Allegiant again."
Pros: "Easy boarding"
Cons: "A little Snack"
Cons: "No help with the Coronavirus bs. Customer service blows"
Cons: "We had a 40-minute mechanical delay."
Pros: "Punta Gorda was not over-busy. So the hassle level of the pre--flight experience was way down from the norm nowadays. The flight was on time, and only mostly full, not crowded."
Cons: "Not even water free infliight is a tad chintzy. Allegiant is not responsible for this, but the seat belt sign was on most of the time. I counld wish for better weather enroute. On arrival at ALB there was not video display announcing the belt numbers fror different arriving flights. One had to just drift from belt to belt"
Cons: "The padding on these seats."
Cons: "I see no reason why the airlines cannot provide a beverage and snack - I think they still make plenty of money off our tickets and how much could this really cost them?"
Pros: "Great crew"
Cons: "Seats are very uncomfortable"
Cons: "Unclear pricing for carry on bag, could have saved $30 by paying at the ticket counter (even though I was sent an eticket and boarding pass); got stuck paying $50 at the gate."
Pros: "Comfortable and inexpensive tickets"
Cons: "It was all good!"
Pros: "I didn't enjoy anything about this flight unfortunately it was my worst experience with an airline that I've ever had."
Cons: "I had checked my bag with was a personal bag and they said it fit inside the metal stand they had so when I proceeded to board another lady had told me I'd pay $50 or wouldn't get on. She was very rude she let me friend with two bags go on without paying. I took four flights and never had this issue"
Cons: "Everything"
Cons: "Offer at least water at no charge."
Cons: "Everything went quickly and smoothly. Great flight; even the weather was less turbulent than expected."
Cons: "Bad turbulence throughout the entire flight. Hot temperature during majority of flight."
Pros: "We had about a 45 minute weather delay but those things can't be helped. The Captain kept us informed and he flew like superman getting us through all that crazy wind coming into Las Vegas. The plane was new and clean, the crew was great. Love that wide aisle...it eliminates that sardine feeling!!"
Pros: "The price of the ticket"
Cons: "Maybe to add WiFi"
Pros: "The staff was friendly"
Cons: "The flight was delayed multiple times, the directions on having boarding passes on the app or printed prior were not given so found that our last minute to avoid paying the front desk clerk $5.00. The flight landed 5 hours later than scheduled which is completely unacceptable."
Pros: "For exception of price there is nothing I liked about"
Cons: "Uncooperative ground crew App doesn't work if you are not from the US"
Pros: "Nothing, honestly. Constantly delayed, cheap airline with forced fees, only one I could take and I can't believe you exist. You have horrible customer service"
Cons: "I will never fly you again. Sure you don't care."
Pros: "The plane was very clean and well lit. The crew was excellent. Very friendly and nice."
Cons: "The seats are pretty uncomfortable. They are so close together and there is no room to store anything. The tray tables are a joke, you can't even fit an iPad on them. The bag check process was trouble at both legs. They have lower weight limits than the major carriers and that really should be highlighted better when you book with Allegiant. Also, bag checkin for the flight I was on started at 7:45am. There were only 2 people at the checkin counter and one of them was busy doing something and ignoring the customers. So that was a little annoying."
Pros: "Going in & out of small airports."
Cons: "We arrived late. Pricing system."
Pros: "Getting off the bus!"
Cons: "2.00 for water! Overpriced everything! Crew was not nice. Kindness goes a long way. Not for this crew impatient and just rude to other passengers. We pay good money to ride on the horror bus!"
Cons: "7.5HR DELAY. LOST A DAY. ARRIVING AT 3AM VS 6:30PM TECH ISSUES NOT ALLOWING CHECKIN ONLINE POORLY TRAINED STAFF AND SUPERIORS AT CHECKIN ONE HR ON TARMAC AS PER HEADCOUNT ISSUE WHEREBY, TWICE ASKED ON PLANE WHO I WAS. EMBARASSING. RUINED MY VACA WITH MY HUSBAND SANS KIDS:-(((((("
Pros: "It is hard to beat the price of tickets for this airline. I love the price; that the flights are direct & almost always on time; that the staff, from the flight attendants to ticket agents, all seem professional, helpful & friendly; and that the planes are clean and seats well cushioned & comfortable."
Cons: "I don't like that the seats don't lean back & that they are very close together with little leg/knee room. Altho the base price for the flights is cheap, they charge for "extras", including making your reservation by phone instead of online, printing out your boarding pass &choosing your seat. There's a fee for carry on's as well as regular size luggage. If you don't prepay for your luggage or if your luggage weighs more than 40 lbs, they charge $50, instead of $25. They not only charge for food, but also for water or any beverage. If you are prepared for a no frills flight & are willing to sit separately from your travel companions, etc. then this is a great way to save time (direct flights) and money. I will choose to fly with them again, even tho My husband & I prob. won't get to sit together. If you know what to expect & plan for it, it is a great way to save."
Cons: "The seating is terrible. Everyone is like sardines packed away."
Cons: "The flight was delayed 9 hrs. We were going to NYC for 2 days. We missed an entire day--- cut our trip in half."
Pros: "Great direct flight to many destinations smaller airports less wait time"
Cons: "seats are crowded"
Cons: "Seats are uncomfortable- they do not recline and the springs in the seat back pole into your back"
Pros: "The staff is always helpful and flights are comfortable."
Pros: "Plane, staff, made best of bad situation. Seats are only OKAY to Good, but NO airlines are really comfortable so by comparison they were good"
Cons: "The delay - this time not due to the airlines, so thus the good review."
Cons: "Left/ arived 30" late"
Cons: "I understand that Allegiant has a pricing structure to implement, but forcing passengers to keep personal items between their feet when most of the overhead compartments were empty was just insulting and ridiculous - not to mention dangerous. In the event of extreme turbulence (or worse), all those personal items would be flying around the cabin."
Cons: "No compliment"
Cons: "Allegiant needs to put more than just school bus seats in their aircraft."
Pros: "Seating assignment before the flight. Direct flights."
Cons: "Felt nickel and dimed to death by extra fees for trip insurance, luggage, and picking advanced seating. Ended up spending more than if we had just chose another airline."
Cons: "We were moved gates a few times. Delayed a few times, finally on a plane and they deboard the whole thing. No one seemed too apologetic at all. Pretty much who cares, after spending money and being moved all over seeming like they cared would've been nice."
Pros: "friendly staff and clean enviornment. no nonsense flight."
Cons: "nothing to say except that seats could be a little more comfortable."
Cons: "Allegiant 468 7/27 4 1/2 hour delay on flight 569 on 7/27 and not a single person on the ground or plane even said sorry. Allegiant also failed to update the revised departure time. Allegiant posted an initial delay of 30 minunutes but then, when there was a further 2 hour delay due to a problem with the plane in Vegas Allegiant didn't update the time. (G4 568 was showing a two hour delay, with a 1010 arrival into STS but Allegiant never updated the departure time for 569 to reflect the additional two hour delay.) It wasn't until I called that it got updated and when I called I had to point out that the airplane hadn't even left Vegas and Allegiant was still showing an 8:50 departure time. It also took the reservation agent over 20 minutes to get any information about what was going on. Lastly each and every time I call I was on hold for a minimum of 20 minutes before being able to speak to a person"
Pros: "Very efficient service... for a first experience we were pretty impressed because your review overall were not that great. Good job."
Cons: "The airline nickel and dimes for everything."
Cons: "First they delayed the flight and then they cancelled the day of and I had to book a whole new flight for the day which was costly. I will never recommend that airline to anyone and I wanted to like it since I looked at their website and it looked very military friendly, but it was just disappointing"
Pros: "No complaints about the trip to Newqrk. Everyone was very helpful and patient since I am an unexperienced flyer."
Cons: "I didn't like thinking I was paying one price then paying another or buying insurance that would have been useless since it doesn't cover anythIntg."
Pros: "I understand the need to make a profit but comfort is probably the most important aspect of any flight......"
Cons: "Min. 40lbs when others are at 50lbs ..... even 2 free suitcases. I understand the need to make a profit but comfort is probably the most important aspect of any flight......"
Pros: "The stewardess remembered us from the previous flight and was awesome to my son!"
Cons: "Kind of bumpy and a little late."
Pros: "The flight attendants were very nice and helpful."
Cons: "Delayed the flight for 7 and a half hours. They then tried to not refund my money"
Pros: "STS ground crew waived goodbye. Love a small town airport"
Pros: "Flight smooth"
Cons: "Extra costs"

Le Butcherettes release 'A Raw Youth', the Teri Gender Bender-led outfit's third album, via Ipecac Recordings.
The focus of the album is the recurring conflict between minorities (the raw youths) and society: The oppressor and the oppressed. Each song is a different story of a youth from a different time era.
Le Butcherettes have released two albums, their 2011 debut 'Sin, Sin, Sin' and the 2014 offering 'Cry Is For The Flies'.
The band, rounded out by drummer Chris Common and bass player Jamie Aaron, recorded the album at RLP Studios (The Morgue Portable Disaster Unit) in El Paso, Texas. Omar Rodriguez Lopez once again produced, as he has done for both previous Le Butcherettes' releases. Guests include Iggy Pop on 'La Uva' and John Frusciante on 'My Half'.
The band have recently toured with Faith No More, Melvins and Antemasque, as well as performing on the 2015 Soundwave Festival.

Q: How big of a lens or parabolic mirror would it take ...to heat a piece of steel so its glowing yellow (1100 C)? Assuming you had a cloudless day at a latitude of, say, San Francisco...
Basically I'm wondering if it is possible/feasible to be able to do basic metal working without a traditional forge, just using the power of the sun to heat the metal. So the diameter of the heated spot would have to be about 6" in order to heat a large enough area of the metal to work it...
I always thought you would need several huge pieces of equipment to do this, but just thought I'd ask if anyone here knew how to figure out it roughly...
Thanks!

A: For steel, the specific heat would be $c_p=0.5 kJ/kg K$, with a density of $
\rho=7000 kg/m^3$. Suppose you want to increase the temperature bij say $\Delta T=1100K$ of a piece of size $V=(15cm)^3$
Then you would need a total energy of.
$$E=\rho c_p V \Delta T$$
Which gives you typically $E=10^7 J$
Now, the power of the sun on a bright day, would be of the order of $p=10^3 W/m^2$.
Assuming that

*

*all the energy input is converted into heat

*the mirror is perfectly aligned

*no heat is lost during heating,

*no melting, e.g. no latent heat

and your mirror had diameter $D$ and you let the process run for a time $t$, then
$$E=p \frac{\pi}{4}D^2 t $$
Then you will get, in approximation
$$D = \sqrt{\frac{E}{pt}}$$
So, suppose you are willing to wait for ten minutes, then the mirror diameter would be $D\approx 4m$. Considering we assumed an ideal system, this is only an order of magnitude assumption.

From Blueprint to Blue Chip: Are EVs public market appetite or a venture capital game?
In 1942, Joseph Schumpeter, published what would become his magnum opus, Capitalism, Socialism and Democracy, an intellectual inquiry into the nature of economics and history. Through this, he coined the term creative destruction, a phenomenon whereby new product or process innovations would slowly but surely completely displace its older counterparts, eventually rendering the old obsolete. Today, many speculate that creative destruction is yet again taking place en masse, this time targeting the way we move from point A to B.
The rise of the electric vehicle (EV) is said to revolutionize the way we transition to a carbon neutral future. A Cambridge study conducted in France and Sweden has found that the average lifetime emissions of EVs are up to 70% lower than those of conventional internal combustion engine (ICE) cars.
Look around at the market, and it seems increasingly crowded with manufacturers. A stumbling block for EVs has always been pricing. However, even that barrier is being circumvented slowly. Some models, such as the Tesla Model 3 and the Nissan Leaf, have already reached an affordable price range of approximately US$30,000 - US$35,000. With more scale, this may tell us that EVs are at the cusp of making the breakthrough for widespread adoption, unlocking a key market that public investors simply cannot miss out on. These indications may build a prima facie case that the EV market is simply a late game for venture capitalists to enter.
However, consider that the EV market still faces one great barrier for widespread market usage: the problem of charging. A further look would reveal that the charging aspect of the EV ecosystem is still very nascent. EVs still command insufficient market demand from consumers and commercial buyers. Beyond just price, the average consumer has two considerations when deciding on making the switch to electric: absence of range anxiety and charging inter-operability.
The current stage of EV evolution has not eliminated the range anxiety problem. Users want wide distance coverage, and when energy is needed for recharging, there must be ample charging points to meet such needs and charging times must be fast. While indeed, vehicle ranges have improved, charging facilities (especially in inter-city passages) are still limited. Moreover, slow charging solutions still take too long. Given these constraints, consumers and fleet operators have less incentive to make the switch. After all, even in the most advanced markets, gas stations still outnumber EV charging points. For the consumer, this relegates EV usage to within the city, while for commercial fleets, the logistics of EV usage is still a bottleneck.
Similarly, vehicle inter-operability with charging points is still yet to be addressed. Go to any gas station, and the nozzle would fit any car you drive. This happens due to market standardization, a process which simply has not occurred yet for EV charging and indeed among EV manufacturers. Taking the Indonesian market as an example, there are currently three plugs: the CHAdeMO, Type 2 AC plug, and the DC Charging Combo Type CCS2 (DC fast charger). However, not all charging points provide all three.
Moreover, charging infrastructure providers have little to no economic incentive to expand the network of charging points, as the market demand for EVs is still too small. The costs for building charging stations still remain extortionately high. According to a UBS report in 2017, the average cost to install a Tesla supercharging station, equipped with 6 -8 DC fast charging stalls each delivering 120 – 150 kW, would be in the ballpark range of US$250,000. Taking Indonesia in context, the state-owned electricity company (PLN) estimates that the country needs at least 31,000 charging points. Assuming Tesla's cost is standard, the required total investment amount to ensure sufficiency of fast charging points would be US$7.75 billion, 10x Tesla's net profit in 2020.
Thus a chicken and egg problem emerges, whereby consumers are reluctant to buy EVs due to the lack of charging infrastructure, however charging providers are unwilling to expand charging infrastructure as not enough people are buying EVs.
The charging problem provides a reminder that the EV market is more than just the vehicles themselves, it also made up of the larger EV ecosystem that support vehicle usage. This means the market for charging, batteries, and even the second-life battery applications. Currently, the larger EV ecosystem is still in its infancy. Where it is too early for public markets to dabble with, is where VCs can find bountiful opportunities. There is a case that the EV ecosystem is still early enough to be venture funding territory.
Take the market for charging. Currently, charging is either too slow for consumers or too expensive for providers to install en masse. Newer and nascent innovations (often VC-backed) are emerging, providing more creative solutions around the problem. The battery swapping solution posits itself as a promising alternative to conventional plug-in charging. Swapping providers install cabinets or facilities whereby fully charged batteries are stored for EV drivers to switch with when needed. Swapping stations are much less capex intensive to build, especially when catered to electric motorcycles, where only cabinets for smaller batteries are needed and can be placed in convenient locations, such as convenience stores. Through this, swapping stations can access better reach to EV users, and thus build an ecosystem for EV usage to thrive. There are no clear market leaders in the swapping segment yet, thus it is likely that we will see competition in funding the various swapping companies before a winner can be declared.
While pricing has become more affordable, innovation in creative financing solutions for EVs have not kept in pace with price reductions. Many emerging market consumers such as in Indonesia, find that while the long-term costs of EV usage may be cheaper, the upfront costs of purchasing the vehicle is still far too high. According to Indonesia's auto industry association, GAIKINDO, close to 98% of the four-wheeled automobiles in the country are in the price range of IDR 300 million (~US$21,000) or lower. Meanwhile most EVs sold in the country are priced above that range. Even in more developed markets, EV is not as widespread just yet. What financing solutions can still incentivize EV usage despite the high price? That is still a subject of ambiguity that creative start-ups and businesses must answer. However, intriguing solutions have been tried in Britain which opens the realm of possibilities. When Renault wanted to sell more of the ZOE model (its EV line) in 2014, it drew up a creative scheme whereby buyers can simply buy the vehicle without the battery. Meanwhile the battery is leased for a lower monthly rate, allowing buyers to pay as low as £49/month. This is brilliant, mainly because batteries are the most expensive component, making up 30-40% of the vehicle's upfront costs. Leasing also helps to spread out the cost burden while easing consumers' fear of replacement costs. After all, a depleted leased battery is less of a hassle to replace than if you own the battery.
Furthermore, the absence of a second life market provides a golden opportunity for VCs to capitalize on. Consumers want some reassurance that after the end of usage, the batteries from their vehicles still retain residual value. Disposal is a costly option. Lithium-ion batteries used in EVs contain toxic components and are flammable. However batteries sit on a pile of gold mine. The minerals that can be extracted from batteries are almost as good as new. According to JB Straubel, Co-founder and CEO of Redwood Materials (a company recycling used EV batteries), up to 98% of the materials in used lithium-ion batteries can be extracted. This includes cobalt, nickel, and copper, materials that are in high-demand and short-supply in the global supply chain. Not only does a second life market provide residual value, it provides a worthy business model.
Schumpeter got the basics right, the future of mobility will inevitably be electric as ICE vehicles would slowly fade into obsolescence. The only question is when? While Tesla and the like may have already become household names and commanded sky high valuations worthy of the blue chips, however the less sexy aspects such as EV charging solutions and second-life processing are still in the periphery of consciousness for most individuals. These are the frontier technologies that VCs have traditionally eyed for. Such innovations will pave the way not only for future returns, but to move the needle forward. After all, overcoming the existential problem of climate change requires every bit of creativity in business and dauntless investors to fund those creative possibilities.

Nutrient Timing: How Important Is It?
(Last Updated On: April 2, 2019)
How you refuel after a workout is important. After an exercise session, you need to replace muscle glycogen stores. That's where carbohydrates come in. It's also essential to get adequate protein after exercising to prevent protein breakdown and help muscles repair and grow. Without the raw materials (amino acids) muscle growth won't take place. That's not the only reason you need protein and carbs. Taking in protein and carbs after an exercise session stimulates the release of insulin. Insulin helps help ferry amino acids into muscle cells where they can use them to grow and repair. There's also evidence that consuming protein after a workout helps with exercise recovery.
Some studies suggest there's a "window period" after a workout where muscles are more responsive to dietary protein. Consuming protein during this period may boost muscle growth and reduce muscle damage more than taking in protein at other times of the day. This is the theory behind nutrient timing. By consuming carbs and protein within a certain time period after a workout, you can maximize muscle recovery and growth while maximally replenishing glycogen stores.
How Can You Use Nutrient Timing to Your Advantage?
To maximize the benefits of your workout, refuel as soon as possible after your workout is over. Some studies show when you consume carbohydrates immediately after a workout, you get the most muscle glycogen replacement. If you wait two hours, muscle glycogen synthesis is reduced by 50%. Why might this be? Right after a workout, enzymes that are involved in glycogen storage are higher and conditions are ripe for glycogen synthesis and storage. By getting carbs quickly, you can take advantage of this.
Carbohydrates aren't the only macronutrient you need during the post-workout period to maximize glycogen replacement. Some, but not all research, shows consuming a combination of protein and carbohydrates after a workout maximizes glycogen replacement more than carbohydrates alone. Replenishing muscle glycogen stores are particularly important if you do a split workout, half in the morning and the rest later in the day. If your muscles are still glycogen depleted during your second session, you won't be capable of working as hard.
Nutrient Timing: Post-Workout Nutrition for Muscle Recovery and Growth
We've already mentioned that a combination of protein and carbs enhances glycogen synthesis more than carbohydrates alone. According to some research, a protein-carb combination stimulates muscle protein synthesis more than consuming a protein meal alone. This makes sense since the protein-carb combination elicits a greater insulin response. This helps to get the amino acids from the protein into muscle cells quickly so they can be used to build new muscle tissue.
How much protein and carbohydrates should you get after a workout? According to research published by the Journal of the International Society of Sports Nutrition, a carb to protein ratio of about 3-4 to one is optimal. Guidelines recommend consuming 0.5 to 1 gram of carbohydrate per pound of body weight during the post-workout period. So, a 120-pound person would take in between 60 and 120 grams of carbs within the window period. Combine this with about a third that quantity of protein. For a 120 pound person, that would be between 20 and 40 grams of protein.
How long is the window period? Most research suggests refueling within 30 minutes to one hour of a workout is optimal.
Nutrient Timing: More Protein Isn't Necessarily Better
You might think consuming more protein after a workout would enhance protein synthesis even more. Not necessarily. There may be a limit to how much protein your body can absorb and use at one time. Even if all the protein from a high-protein meal is digested, the amino acids have to be transported across the small intestines and enter your bloodstream to reach muscle cells. There are a limited number of amino acid transporters available to do this job. Some research suggests that we can't absorb more than 20 to 40 grams of protein at one time. So, consuming more protein than this at one meal may be pointless.
Don't assume you need to drink a protein drink to get protein to your muscles quickly. A high-protein snack with an appropriate amount of carbs will work. If you use a protein supplement, whey protein is absorbed more quickly than casein. Whey will reach your muscles more quickly while the amino acids from casein are absorbed more slowly into the bloodstream. There are advantages to delivering amino acids quickly to the muscles you've just worked. This gets them on board quickly to maximize protein synthesis.
Casein has its advantages too. Because casein is more slowly absorbed, it helps to reduce muscle breakdown after a workout. One way to get the advantages of both without using a supplement is to drink low-fat milk. A glass of low-fat milk supplies your body with around 28 grams of carbs and 8 grams of protein. The protein in milk is 80% casein and 20% whey. Maybe add a little whey protein to your low-fat milk?
The Bottom Line?
Post-workout nutrition is important for replenishing glycogen stores and for muscle repair, recovery and growth. Nutrient timing may also influence glycogen replenishment and muscle protein synthesis. Eat a protein-carbohydrate meal within 30 minutes to an hour after a workout. Wash it down with a glass of low-fat milk so you can benefit from both quick-absorbing whey and slower-absorbing casein. Remember, building the body you want has as much to do with nutrition (or more) as it does with exercise. So feed those tired muscles so they can recover and grow!
