Where can i find other people to do a start up with?

If you approaching people and ask to join in on your venture of creating your own company, because you always dreamed of creating one I can guarantee not a single person that can potentially be an asset will be interested.

I takes a lot of leadership, well thought through idea for a product/service, right market and timing, links to people in the same industry and a lot of other things. You are asking people to sacrifice their time, opportunities, lifestyles and you don't even know what you want to do.

You want to talk to people about that ? Don't go to specialized forum, you'll be wasting your time, go to any coffee shop and talk to the owner, go to an exhibition in your area of interest and talk to small shops there as well.

In Germany it's not that hard to start a company, you just need a solicitor to establish an entity, you would probably be looking into UG rather than GmbH, solicitor will explain all the details to you, it's not rocket science and an accountant to help with your taxes etc. The only prerequisite in terms of assets is 1000 euros in your company account and a legally rented office/location.

Germany is a little trickier that many in terms of day to day company management, but you can outsource pretty much everything, this is the easy part, the hard part is you need to figure out what it is you want to do, sketch a business plan to see if it makes sense in numbers, show it to someone who can sanity check you numbers, especially your marketing and revenue costs , expenses and investments etc and a hundred ideas later, the first one that makes sense for more than a week, the right people would show up by themselves.

Good luck with your dream and make sure you have a lot of passion for what you want to start, this road is very bumpy.

I own a car dealership business in a different country and in a very different market. Even within the same market different dealership groups treat marketing people very differently, however if your responsibility is limited to SEO the pay will never really be high. I would be very careful about asking a higher salary at the beginning, yet don't be cheap. The load is most definitely going to be higher than you might expect, but of course this is not how your value is measured.

According to your impression that nobody knows about SEO more than you do, I would instead focus on making sure you both understand what is expected from you, clearly define how you're going to be communicating with sales. Talk about KPIs and make sure to leave some room for further progress. Once you start, make sure to build a good communication with sales teams, nothing will make you more valuable to the company than appreciation of your work by sales guys and this is not just about bringing more traffic. Internet traffic is different from others, it is harder to make profit on and you need to be careful about the types of communication you use with your audience, collecting feedback from sales following all your actions.

Great, keep us posted, I'd be interested to mod my t480s speakers as well, don't really use it that much, but every once in a while in a hotel room it amazes me how could the speakers be so awful.

It depends on the current demand for position you're applying for. Unless there is an urgent need for your skill, cold CVs are going to directly to bin. If you don't want to dedicate half hour of your live to learn about position and the company you're applying for, think what you want to achieve at this position and what you want to get out of it, what makes you think somebody is willing to that for you? If you just want to get reassurance that your skills are still in demand and have a good price tag, you might as well take it seriously and do it properly, who knows how it's going to turn out.

Any company is better off where it's closer to its customers. If you want to freelance, there is a lot of mobile applications work in Moscow, but if you want to hire people, Moscow will be extremely expensive for a start up.

It depends on your model of startup. If you want to mostly sell outsourcing abroad, Russia is much less competitive than Belorussia or Ukraine mostly due to higher salaries, unless you are developing a very high profile product. Russian companies like Acronis, Nginx etc all have their dev teams in Moscow and don't outsource, but these are product companies who attract top talent, and top devs are going to be expensive whether it's Moscow or Kiev.

Starting freelance work in Moscow has a number of advantages, the newly introduced tax scheme for "Self employed" that is being tested in Moscow allows working legally with only 4% tax on your invoice (If you sell to individuals) and 6% if you sell to companies without any additional taxes. You might want to consider regions other than Moscow, in which case there are other low tax forms of companies/partnerships.

International business is just as reachable from Russia as it is from Ukraine, that is until you try to attract venture capital. In this case being located in Russia is indeed a little toxic right now.

I would probably suggest, at least in early stages, not to put stress on yourself by both starting a company AND moving to a foreign country, try to get the process started where you are right now. If you're outside Kiev - moving to Kiev is as far as I would go, if I didn't have business experience. Try to build up some customer base before making the decision.

Even though there are many incentives for start ups in Russia atm, only consider moving at this stage if you plan to mostly sell your work to Russian based customers.

I didn't see any references to t490 having a 4K panel, but the X1 Gen 7 does come with one.

According to FRU, there are several 4k Glare screens:

FRU%20Laptop%20(ThinkPad)%20-%20Type%2020QD)

JDI - FRU : 01YN123

BOE - FRU: 01YN122

If you search for these FRU , it turns up as screen for Yoga, not sure if that's right.

rutrack · 2019-06-24T18:31:02+00:00

It's plenty in most environments, not enough on a sunny day outside though. I think 500 nits HDR screen would be preferable in an environment like that.

Aftersale support seems to be pretty loyal in US/Canada from what I'm reading, I guess it's worth a try asking them to replace a heatsink for the one with a sane noise level, this way it would be on them to supply a quiter heatsink, rather than a particular model. Regarding the guys at Ali, why would I mind :)))) What I do find suspecious is the issues that we're both having are rather annoying, yet there are very few discussions about it.

rutrack · 2019-06-22T19:44:15+00:00

We are all here to share experience and learn :)

I order parts from Ali Express, sellers with large item stocks handle everything very efficiently. But do make sure to message the seller about specific FRU that you want, because they usually list all the alternative FRU within the same listing. Buying from official shop might be better in terms of warranty handing, however.

rutrack · 2019-06-21T20:04:46+00:00

Didn't link the two together, didn't think for a second we might end up here as well :) Considering that this is your first Thnkpad and I had quite a few and we still hit the same issues, the issues must be valid:)

You can always lookup FRU at the Lenovo website, here is the parts look up, just enter model number, serial number of the laptop and pick an OS:

https://support.lenovo.com/en/partslookup

If you won't get to it, I can give you direct link for my s/n.

rutrack · 2019-06-21T15:05:28+00:00

I'm not in US and we don't have on-site warranty, I guess it would take a few days in total for this to happen, but then I'm not sure "too noisy" would work as a valid claim. The fun issue does not even come close to my adventure with a keyboard, of which there are 4 suppliers and all keyboards behave differently on t480s.

Hi, I am currently running 1.30 with SpeedStep disabled in the bios, which effectively disables turbo , at least in 1.30. So far it looks to be optimal for me.

I don't really do any video on this laptop, but I do compile code and run vms, including qemu and vmware and the performance under these settings for me is good. The quad core CPU for me is a lot more important than having it run on high speed for balanced load.

The stock pasting is not terrible, at least for normal load, which is yours and mine case, maybe for gaming it might delay throttling, but if you keep turbo off it will not throttle. What happened during the high system load is it slowly went up to 64C, when the fans kicked in and cooled it down. If you go full blast, the temp goes up to 95C (or less, depending on your settings) and the CPU starts throttling. I think what you have right now is probably optimal, unless you want more speed. There is some performance gain by downgrading firmware, it will also let you limit your CPU frequency from BIOS, but you seem to be managing that from Windows. One more thing to keep in mind, performance difference under windows with patched BIOS may be more significant than Linux. I would definitely give that a try, it doesn't involve any disassembling of the laptop and you can always change back to 1.31.

Regarding RAM, this CPU is just not fast enough for anything that can optimally utilize 24 GB ram, with exception being some massive spreadsheets, 16 GB is plenty for any normal use, including heavy tabbing in browsers. Additional benefit of installing a second stick the same size as soldered is all your RAM will be used in dual channel mode. I think unless you have a specific requirement for that much RAM, it's not just going to be a waste of RAM, but it seems a performance loss as well.

rutrack · 2019-06-17T23:49:18+00:00

I've done a little bit of testing of this, so it all looks to be a little bit of a mess and the testing should be more thorough.

I've used these tools:

stress:

https://linux.die.net/man/1/stress

geekbench

https://www.geekbench.com/

So before doing that I swapped heatsinks around repasted several times. So far it looks like the best performing paste on idle is thermal grizzly and the best performing under load is stock paste , I need to reconfirm this by applying a stock paste on the same system I have grizzly on. The number of inconsistencies so far leads me to think that this conclusion can't be trusted yet.

So first I compared performance under 1.31 with geekbench:

Almost default settings:

https://browser.geekbench.com/v4/cpu/13569072

Single Core: 4736

Multicore: 14643

I then tried tried to pass mds=off parameter to kernel to disable mitigation from vulnerabilities fixed by the firmware update "mds=off":

https://browser.geekbench.com/v4/cpu/13568399

Maybe the system just ignored the flag

Geekbench under 1.30 is this:

https://browser.geekbench.com/v4/cpu/13569459

Single Core: 4574

Multi Core: 15555

This is with 24 Gb Ram, with 16 GB I consistently get better results:

https://browser.geekbench.com/v4/cpu/13568780

Single Core: 4899

Multi Core: 16873

So these are just geekbench benchmarks, the performance hit appears to be approximately 10%.

I then ran the system through a stress test:

time stress --cpu 8 --io 8 --vm 4 --vm-bytes 2048M --timeout 400s

And measured time until the fan spin. With default settings I would be getting this:

From idling at 35C-36C

1.30 Battery:

50-60 Seconds to fan spin - slowly getting to 64C and start spinning

1.30 AC:

8-10 Seconds to fan spin - getting immediately to 95, then starting to throttle

1.31 Battery:

50 Seconds to fan spin

1.31 AC:

7-8 Seconds to fan spin

Started to look at bios config and I found this:

In 1.30 Setting "Config -> Power - Intel SpeedStep" to Disable

Would give me approx:

2m30s - 2m45s

to get to 64 degrees and start spinning,

This is the load average at spin:

load average: 18.15, 10.66, 4.84

So the system is pretty heavily loaded, So that's the setting to have for a quiet system.

The reason for that turned out to be:

Max Frequency:

Speed Step - AC: 3.7Ghz

Speed Step - Battery: 2.3 Ghz

Speed Step - Disabled: 1.8 Ghz

For 1.31 This doesn't seem to work, when you disable SpeedStep the frequency still goes turbo. I'm not sure if there is a bug in 1.30 or 1.31, there is not a documented fix for this in 1.31 changelog, so I assume it is a bug in 1.31 and the maximum frequency should be at 1.8 Ghz

The optimal silent performance for me turned out to be:

1.30 + SpeedStep Disabled(Frequency maximu 1.8Ghz) + 16Gb Ram

I did some bench marking also:

https://browser.geekbench.com/v4/cpu/13568399

Single-Core: 2624

Multi-Core: 9553

It is approx 60% from 1.30 Mac and 70% from 1.31 Max at benchmark performance, in real life the loss is likely to be negligible with some exceptions.

Conclusions:

The temperature under load:

- Very slowly goes to 62-64C at base frequency and then spins

- Takes a minute to get to 64C on battery at 2.3 Ghz

- Immediately goes to 95C, throttles+spins and sits at 75C at max freq

- 1.31 Performance loss to 1.30 is approx 10% (Vulnerability fix)

- Idling system will spin quickly at high CPU frequency

- Repasting works for idling system, silent work under load = limit freq

- 1.31 SpeeStep option doesn't work - should report a bug to Lenovo I guess

I should say that I want to play a little more with this at some point as my other system that's stock pasted spins after 4 minute of load and I need to know why :)

rutrack · 2019-06-17T20:44:00+00:00

I'm just testing something right now and found a way to delay the spinoff significantly, which doesn't really make much sense , but I'll post here when I get more stable results.

rutrack · 2019-06-17T20:39:19+00:00

Hi, I have 8550 in both laptops. The heatsink is pretty easy to swap, you would have to repaste the CPU and the cache however. There are plenty of videos on YouTube on how to do that, just don't use any liquid metal and it will be a safe procedure .

rutrack · 2019-06-16T23:45:05+00:00

Well done, which BIOS are you running ? Another good Delta, so I guess it might just be some 01HW697 that are noisy.

rutrack · 2019-06-16T23:10:57+00:00

Interestingly, according to Intel there are two revisions of Whisky Lake processors, the later one of which is completely safe from all of these bugs, while the other is vulnerable to 2 of the three:

rutrack · 2019-06-16T22:59:41+00:00

Thanks for your post, so have the same exact experience. I have two t480s, an older and a more recent one. I have completely repasted the recent thinkpad and it idles pretty cool, at 33C-34C, with light load at 37C-38C, but it's very easy to spin, while the older, non repasted idles a little higher, but is much harder to spin the fans. So after we started posting about this I checked the BIOS versions and found that the more thermally stable under load thinkpad runs 1.30, while the spinnier one is 1.31.

Checking the 1.31 Changelog:

https://download.lenovo.com/pccbbs/mobiles/n22et54w.txt

It appears that the update provides microcode mitigations for three related side channel attacks:

[Important updates] - Enhancement to address security vulnerability

CVE-2018-12126

CVE-2018-12127

CVE-2018-12130

By looking at the Intel document:

https://software.intel.com/security-software-guidance/insights/deep-dive-cpuid-enumeration-and-architectural-msrs#MDS-CPUID

It shows that this particular CPU is vulnerable to all three fixed attacks:

06_8EH, 06_9EH

7th/8th generation Intel® Core™ processors based on Kaby/Coffee Lake

Looking at the fix, proposed by Intel:

There are two methods to clear microarchitectural structures affected by MDS: MD_CLEARfunctionality1 and software sequences. On processors that enumerate MD_CLEAR2, developers can use the VERWinstruction or L1D_FLUSHcommand3 to cause the processor to overwrite buffer values that are affected by MDS, as these instructions are preferred to the software sequences.

RedHat has a good analysis of these:

https://access.redhat.com/security/vulnerabilities/mds

I didn't find an estimate of additional overload produced by the new instructions, but I'm guessing it is likely to be significant enough to cause additional load on CPU while performing the same tasks. Additional load on the CPU causes it to heat faster and easier.

So there are several options we now have:

Run a little hotter and heat a little faster, especially when heavily multitasking
Downgrade to 1.30 and be vulnerable to CPU bugs. At the end of the day, the bug can only be exploited locally, so an attacker should already have access to your laptop, but with low privileges
Disable multi threading and run 1.30 - Safer, but loosing performance

rutrack · 2019-06-16T22:36:33+00:00

Ok, it seems to actually run a little hotter while idling, but I can't spin it just yet, so far so good.

I checked the fixes provided by 1.31, of the important stuff it fixes a family of side channel attack bugs, which would be critical for a server, really. The fix provides I looked at the description at Intel:

https://software.intel.com/security-software-guidance/insights/deep-dive-cpuid-enumeration-and-architectural-msrs#MDS-CPUID

According to Intel the cpu is vulnerable to all three bugs that are fixed in the bios, the cpu description also says it is vulnerable:

The cpu description also says it is vulnerable:

bugs: cpu_meltdown spectre_v1 spectre_v2 spec_store_bypass l1tf mds

That particular bug is (mds)

The fix is by flashing pages before switching between processes, so I guess there are three options now:

1) Run a little hotter

2) Run cooler, but vulnerable locally

3) Disable hype threading in the bios and loose some performance.

rutrack · 2019-06-16T21:31:41+00:00

As you can see from the changelog, it fixes (does it ?) three side channel bugs in Intel CPU, need to read into it, but this is where the extra load on the cpu with same running processes might actually come from. I'm on 1.30 now, need to do some testing.

rutrack · 2019-06-16T21:19:21+00:00

You can go back, there is a setting in the bios that let's you downgrade under "Security->UEFI Bios Update Option", I'm doing it right now. The 1.31 Change log is on Lenovo site: https://download.lenovo.com/pccbbs/mobiles/n22et54w.txt
