4790 and 4790k 都係介乎$1800～1900
Me ng buy 2nd hand hardware
Nah, there's no points for buying old stuff
Yr hardware are much more expensive
上次世界盃嗰陣，PCCW 應該就係咁樣 Carry 個 4K 信號返香港
SDI 12Gbps 老實講衛星應該點到 Carry 唔到
同埋要睇下個條野係機房駁住部 ONU 係咪 XGPON Capable
Google 又來投資海底電纜，叫做 JGA（Japan-Guam-Australia）
希望未來有技術突破到APAC 連去 US WEST 會低 ping
btw 乜7 係 CN2 cable, 見D大陸 vps host 瘋狂sell
CN2 = China Telecom Next-generation Carrier Network
delay 好正，因爲用咗好少人用嘅 SAFE Cable
Pccw係唔係都賺我地咁多上網費， 點解要upgrade
話 Netvigator 上網貴一定係未拉過 PCCW Global
Google 租咗 1.28Tbps 嘅 C2C 係香港返去臺灣個 DC
第一條唔經日本直去美國嘅海底電纜，係 Singtel，PLDT，PCCW，China Telecom，VNPT 等等嘅亞洲 ISP 一齊投資嘅
有 但係係 Stylistic Representation
licson 你最近係咪借左個 ser 比 傻仔 Austin test?
因為琴晚佢叫我幫佢 test 抗 DDoS, 所以先問下姐
你唔好話你尋日 DDoS 我條 HKT 2x1G……
定係你嗰啲 DDoS 係多人玩 stress test
老老實實，而家D DDoS service 好 L 犯濫
我諗緊要唔要整個 Cisco Layer 3 Switch 變 NAT router 嘅教學
然後的 Cisco 二手貨部部都搖身一變成為家用 router
enable
config t
interface gi0/0
ip address dhcp
ip nat outside
interface gi0/1
ip nat inside
ip address 192.168.1.1 255.255.255.0
ip route 0.0.0.0 0.0.0.0 gi0/0
access-list 50 permit 192.168.1.0 0.0.0.255
ip nat inside source list 50 interface gi0/0 overload
不過 Switch 既話，要將 gi0/1 換 Vlan1
True link aggergation w/ redundancy
算係咁啦 話曬都換左2次display card 又清左幾次塵
spam the online reg link everywhere
係我個 WTT Account Manager 寄信比我我先知
話說 HKT 2x1G 可以用祕技變到八個 IP 出嚟
其實同一個 LAN 就算唔使 VLAN 都可以 Carry 幾個 Subnet
因為啲裝置可以自己透過 ARP 搵返同 Subnet 嘅裝置
同埋PKKW 嘅Subnet mask好似set咗32嘅
Currently 1 modem 2 router 2 ip
I’ve searched this before
Tho I’m not using this shit
辯論係各持已見
但公有fibre 應該係本台共識，無人反對，因為根本係正苦telco同消費者共同得益
但係上網上下載尖峰時間得30mb, 想直插 fibre
整左national 5G，以後無得部份電訊公司用地產霸權係某屋苑有優勢
唔會，頻譜公有，電訊公司租發射站同spectrum
me平時一日做Seed Upload 200-400GB到
順便講一下，家居寬頻個 OLT Uplink 大水喉過 商業寬頻
又或者你直接放部機入機房自己拉線駁 ISP Backbone
ISP 賣個 port 位連 Bandwidth 比你
應該係全部都有train , 不過少做 DWDM 姐
以前問過 HGC，1Gbps Leased Line，20000
MacBook Pro > SAN > rsync to Google Cloud
個SAN 係想做快既media editing ，做完會扔返落SAN，rsync上Google cloud，然後SAN 會purge
Lots of second-handed goodness
Big companies buy lots of them and changed solutions, so a lot of second-handed disk shelves
1. 將 LSI HBA 插落你電腦
2. 將 SAS 線插落電腦同埋碟櫃
3. 碟櫃裝返啲硬碟
4. 插電，開着電腦同埋碟櫃
你電腦會自動 detect 到好多隻碟
其實vmware隻碟好似都係行virtual iSCSI
