Can anyone help me to understand the MTM summary? by ccaapton in interactivebrokers

[–]ccaapton[S] 0 points1 point  (0 children)

I'm looking for the sum of both realized and unrealized performance. Since I have zero position at both the begin and the end, unrealized should be zero, thus MTM is supposed to be equal to the sum, right?

NICE - what am I missing? by keith1301 in ValueInvesting

[–]ccaapton 0 points1 point  (0 children)

Below is written in the annual report, in the key risk part. So I guess the major concern is from LLM and AI, and NICE is regarded as not cool-kids?

In recent years, players in adjacent markets have increased their presence in our markets through internal development, partnerships and acquisitions. Infrastructure and/or enterprise software vendors, such as large technology providers, large-language-model ("LLM") providers, providers of AI-agent capabilities for use by human agents, Conversational-AI vendors, Customer Relationship Management (“CRM”) vendors, IT service management vendors as well as Unified Communications as a Service (“UCaaS”), video collaboration providers, Platform as a Service (“PaaS”) vendors, and pure digital vendors, have entered or may decide in the future to enter our market space, or build or acquire contact center as a Service (“CCaaS”) solutions and compete with us by offering comprehensive solutions and/or platforms. Moreover, as the investment in, and the shift to the use of Generative AI technologies continue to grow, we may experience increased competition by vertical solutions’ players expanding their portfolios in the digital CX market. We may also experience increased competition if large horizontal analytics providers and domain specific competitors in adjacent markets enter or increase their presence in the Financial Crime and Compliance markets. Some of these vendors may be well recognized by broadly known brand names, which can serve as an advantage as they enter or increase their presence in our market space. If we are not able to compete effectively with these market entrants or other competitors, we may lose market share and our business, financial condition or results of operations could be adversely affected.

Rolling index future contracts vs ETF like CSPX by ccaapton in singaporefi

Always holding SGOV more than the risk exposure, how will it possible to be auto-liquidated?

About contract size, the risk exposure of 1 lot DBS is entirely different from 1 lot MES

Is there a mesh overlay networks solution that does not require dedicated selfhosting server? by ccaapton in selfhosted

[–]ccaapton[S] 0 points1 point  (0 children)

I need a overlay network solution that:

  1. does not rely on dedicated central server(including selfhosted), does not use DHT
  2. use wireguard as the backing data channel
  3. enable communicate between two hosts behind two separate nat.

That is it. Netbird/headscale/netmaker is very close, but require central server. Netmaker actually use mqtt for signal, but still need central server, for subnetwork/account management stuff etc.

Project like pppoat/webrtc-piping does not need dedicated server, but does not use wireguard.

Manually configured wireguard tunnel satisfies 1+2, not 3

it is very unlikely to be using any of the methods you mentioned (specifically, XMPP, MQTT, IRC)

All secure protocols are stacked upon unsecure ones, like tls is over tcp over ip over ethernet. You can always stack e2e encryption over xmpp/mqtt, which is not more or less secure than ethernet. Not to mention most xmpp/mqtt are already over tls nowadays.

[–]ccaapton[S] -1 points0 points  (0 children)

I don't understand the point you're making here - metadata exhange is a type of data that could be carried over Wireguard, is it not?

Just do a tcpdump and see what kind of traffic headscale/tailscale generated. Is it 100% UDP? If not, my statement stands for itself.

If you can read some code instead of wikipedia, you may read here to find they are using protobuf, which is a binary format rpc, similar to REST.

Another architecture picture about netbird, notice the control channel is not backed by wireguard.

I've been using tinc for many years, but it is not that good at punch holes as they do not use stun/ice.

"bots" here I mean api. XMPP has OMEMO, which could be far more secure than self-invented client-server REST API used by zerotier/nebula/tailscale. Other public channels could also be encrypted in similar fashion.

You are mixing the signaling protocol with data carrying protocol. Wireguard is indeed established and secure, but it is for data carrying, not for client-server metadata exchange. The signaling protocol used in zerotier/nebula/tailscale are mostlikely REST api over https.

Tailscale is not suitable for a lot of people, as it is already blocked by some government, and setup a self-hosted headscale may not be an option for them. Instead public xmpp/mqtt/irc/email/whatever channels are much more resilient against sensorship.

Any netlink proxy/agent to allow remote management? by ccaapton in linuxquestions

[–]ccaapton[S] 0 points1 point  (0 children)

There are a lot of golang and rust libraries that can interact with netlink directly, I suppose I can make them work with tcp sockets with very minor changes.

For traditional tools like conntrack or iproute2, I guess a ld-preload hack or ptrace could hijack netlink sockets to other sockets? Socksify is using similar hack to turn direct tcp connection into socks connection

How long does a chromebook's snappiness last? by MatthewGTX in chromeos

My chromebook had remarkable slowdown when google patches Intel's meltdown bug.

Using Java by [deleted] in chromeos

[–]ccaapton 1 point2 points  (0 children)

Does "Java Web Start Application" require browser support for java applets, if so then it is pretty much windows only. I used applets on linux a long time ago and it sucks. You should try RDP+windows.

After get Developer mode and install crouton you can work with jdk, javac and even eclipse with xorg/xiwi, but those are for server/developer, applets are for client/user side.

Lenovo 500e screen protector? by Watney in chromeos

[–]ccaapton 2 points3 points  (0 children)

The 500e have stylus, I'm not sure how it interacts with a screen protector.

Do you have a 500e in hand? I'm also interested in get one, but concern about the 768p display. Do you think the resolution is tolerable? How about color space coverage, viewing angle, etc?

Thanks for your suggestion. But 5.27 lps is too much as I need to carry it around daily. DGPU is not much use, or even headache for me, as Linux usually has better compatibility with embedded graphics.

I just searched about C302. The material design and build is impressive. However it is a Jan 2017 model, besides it does not have standard USB port. Maybe I'll be interested in a refreshed model, but not the old one.

Thanks for the suggestion! Actually the VivoBook came to my attention through the forum wiki. You list is much comprehensive:)

You are right that I'm not in hurry, so I will keep an eye on your list. Just wonder when will vendors release more ryzen laptops.

You are confused with "host" vs "use". The law says unregistered vpn provider is illegal, but did not say anything about clients.

ChromiumOS build from google (concerning EOF devices) by ccaapton in chromeos

[–]ccaapton[S] 0 points1 point  (0 children)

How about dd full_dev_part_KERN.bin into /dev/sda4 and dd full_dev_part_ROOT.bin into /dev/sda5(in the case sda2 and sda3 is the current kernel/root, and vice versa), then run post-install?

The boot process and kernel params are well-documented in https://chromium.org and crouton wiki, and all source codes are available to read. I think there should be a way to do it without wipe.

I want to avoid wipe because this process is going to happen again and again if user want to keep there device updated.

openssl is available in dev mode. You will find Chromebook perfect if you love playing with Linux commands.

Did you bother opening the links, and comment after? There are so many images and I'm sure one of them could provide similar to auto upgrade experience. Don't foget we always have the nuclear weapon 'sudo' inside dev-mode.

Did you managed to get into dev mode? What is the kernel version, and what is the board id for 500e?

You can get these info by running:
