With FC being the protocol of selection for accessing business-critical enterprise datasets, an necessary side of a safety posture is to validate the identification of adjoining switches and to encrypt information whereas in transit on a storage space community (SAN). These capabilities are supplied on the Cisco MDS 9000 household of storage networking units utilizing Cisco TrustSec FC Hyperlink Encryption. With current NX-OS code, a brand new cypher has been launched to face up to the brute-force calculations that may overcome present encryption requirements with quantum computing, that includes a simple configuration. Obtainable below Benefit and Premier license tiers, this function helps director switches, fastened configuration switches, and multiprotocol switches, benefiting each mainframe and open system environments.

Authentication is a prerequisite to encryption

Cisco MDS 9000 Sequence Switches implement the Fibre Channel Safety Protocol (FC-SP-2 normal, ANSI INCITS 496-2012), enabling switch-to-switch and host-to-switch authentication to handle safety challenges in enterprise materials. The Diffie-Hellman Problem Handshake Authentication Protocol (DHCHAP) is a FC-SP protocol that gives authentication between Cisco MDS 9000 Sequence Switches and different units. DHCHAP combines the CHAP protocol with the Diffie-Hellman (DH) change, guaranteeing that solely trusted units can be part of a cloth, thereby stopping unauthorized entry.

DHCHAP is a safe, password-based key-exchange authentication protocol supporting each switch-to-switch and host-to-switch authentication. This configuration requires setting native and peer change passwords, with DHCHAP negotiating hash algorithms and DH teams. With NX-OS 9.4(3), SHA-1 algorithm-based authentication is default, configured on the bodily FC interface degree.

Cisco TrustSec Fibre Channel Hyperlink Encryption

The Superior Encryption Customary (AES) is a high-security, symmetric-key block-cipher algorithm adopted globally since 2002. It helps varied purposes, together with disk encryption, VPN methods, and messaging applications. Its substitution-permutation community entails subtle bit operations, with hardware-efficient execution.

Cisco TrustSec FC Hyperlink Encryption extends the Fibre Channel Safety Protocol (FCSP), guaranteeing transaction integrity and confidentiality utilizing DHCHAP for peer authentication. Encryption configuration entails defining safety associations on interfaces, setting a key and utilizing a salt for enhancing safety by differentiating encrypted textual content patterns.

Cisco TrustSec FC Hyperlink Encryption allows AES-GCM (default, encryption and authentication) or AES-GMAC (authentication solely). Key lengths supported are 128 bits for 32G units and each 128-bit and 256-bit for 64G units, providing flexibility and selection. If executed in software program, AES-128 is marginally sooner and desires much less system assets, whereas AES-256 supplies higher resilience in opposition to brute-force assaults and elevates the answer to turn out to be quantum resistant.

Mounted configuration and multiservice switches leverage the identical capabilities, however the variety of encrypted ports is determined by the change mannequin. For instance, on Cisco MDS 9124V there are 4 ports that may be encrypted, on Cisco MDS 9148V there are eight, and on Cisco MDS 9396V there are 16.

Port independence and repair availability

In real-world deployments, port independence is essential for sustaining connectivity throughout disruptions. Cisco MDS 9000 Sequence Switches excel on this, with an optimized ASIC structure and body path separation guaranteeing no impression on different encrypted ports throughout occasions like port errdisable or cable/SFP pull. This functionality enhances service availability considerably.

Cloth switches like Cisco MDS 9124V, 9148V, and 9396V assist a number of encrypted ports with out lowering the overall variety of usable ports, in contrast to competing merchandise. This functionality ensures constant useful resource allocation no matter encryption standing.

Distance assist and SAN analytics compatibility

Enabling encryption on MDS 9000 Sequence units doesn’t have an effect on supported distances, preserving buffer credit and permitting unaltered long-distance operations. Customers can preserve the identical distance capabilities with encryption, eliminating design constraints throughout safety planning.

Cisco SAN Analytics supplies deep site visitors visibility and is the {industry} benchmark. It may be totally relevant to encrypted site visitors, sustaining assurance and insights with out compromising visibility. The superior structure of the Cisco MDS 9000 Sequence ensures that it’s at all times attainable to examine headers, in order that SAN Analytics may be utilized to encrypted site visitors coming into the change or leaving it.

Key size, rekeying, and quantum resistance

AES-GCM helps 128- and 256-bit keys. Key choice on 64G units presents flexibility, with guide periodic rekeying accessible as an extra safety measure. AES-256 is favored for quantum resistance and safety in opposition to the rising threats posed by quantum computer systems, together with Grover’s algorithm. The improved TrustSec functionality on MDS 9000 is taken into account safe not less than till 2050, as per ETSI GR QSC 006 V1.1.1, future-proofing safety efforts.

Tim Cook dinner selected poorly | Cell Dev Memo by Eric Seufert


Yesterday, Decide Yvonne Gonzalez Rogers, who has presided over the Epic Video games v. Apple case because it was introduced by Epic in 2020, dominated that Apple violated an injunction issued in 2021 that compelled Apple to permit builders to hyperlink to exterior account administration techniques, together with for funds. From the WSJ (emphasis mine):

A federal choose hammered Apple for violating an antitrust ruling associated to App Retailer restrictions and took the extraordinary step of referring the matter to federal prosecutors for a legal contempt investigation … The order is the newest twist in a long-running authorized dispute between Apple and Epic Video games, developer of the favored videogame “Fortnite.” It accused Apple of monopolistic habits in a 2021 case associated to the tight controls it imposes over app makers … Rogers largely dominated in Apple’s favor within the 2021 case however required the iPhone maker to permit builders to supply customers different strategies for paying for companies and subscriptions exterior the App Retailer … Apple mentioned it might adjust to the order. The corporate disagrees with the court docket’s choice and can enchantment, a spokeswoman mentioned.

Apple had appealed the unique ruling, which was upheld roughly two years in the past, in April 2023. In my protection on the time, in a chunk titled The Epic v. Apple enchantment choice will change little or no, I argued that forcing Apple to permit link-out and different types of different funds would have little affect on the app economic system as long as Apple continued to pressure builders to pay fee charges on these transactions. From that piece:

And Apple and Google have each dug their heels in on amassing a platform payment on different funds. Apple launched entitlements associated to each in-app and out-of-app different funds as a way to acquire a 27% payment on IAPs in courting apps within the Netherlands, the place the home competitors authority dominated that different funds (completely in courting apps) have to be supported. And Google and Apple each extract a 26% payment on different funds processed in South Korea, the place a regulation was handed in 2021 to claim the identical. And Google introduced final week that it’ll permit different funds in Google Play within the UK following an investigation by the UK’s competitors authority, however that it’ll extract a 27% payment on these funds … If these charges are extracted on different funds, given the conversion friction inherent in monetizing customers exterior of native fee mechanisms, the economics of “by-the-book” different IAPs for cell sport builders will merely break.

I’ve chronicled Apple’s makes an attempt to keep up its fee on out-of-store transactions in my Apple to builders: Heads I win, tails you lose collection (see elements one, two, three, and 4). My argument all alongside has been that, if Apple is allowed to use its vital fee on transactions that happen out of the App Retailer, the economics of fee options are merely unworkable. This ruling modifications that, nevertheless: in a withering 80-page choice, Decide Rogers determines that Apple not solely violated the injunction but additionally that an Apple government lied beneath oath through the trial. And with this choice, with which the corporate should comply instantly, Apple’s ironclad grip on out-of-store funds has been damaged. Whereas different developments on this case have largely been insignificant, this one isn’t: it’s really a watershed second for the app economic system (noting that Apple plans to enchantment).

From the choice (emphasis mine):

Apple’s response to the Injunction strains credulity. After two units of evidentiary hearings, the reality emerged. Apple, regardless of realizing its obligations thereunder, thwarted the Injunction’s targets, and continued its anticompetitive conduct solely to keep up its income stream. Remarkably, Apple believed that this Court docket wouldn’t see by its apparent cover-up (the 2024 evidentiary listening to) … In stark distinction to Apple’s preliminary in-court testimony, contemporaneous enterprise paperwork reveal that Apple knew precisely what it was doing and at each flip selected probably the most anticompetitive choice. To cover the reality, Vice-President of Finance, Alex Roman, outright lied beneath oath. Internally, Phillip Schiller had advocated that Apple adjust to the Injunction, however Tim Cook dinner ignored Schiller and as an alternative allowed Chief Monetary Officer Luca Maestri and his finance crew to persuade him in any other case. Cook dinner selected poorly … That is an injunction, not a negotiation. There are not any do-overs as soon as a celebration willfully disregards a court docket order. Time is of the essence. The Court docket won’t tolerate additional delays. As beforehand ordered, Apple won’t impede competitors. The Court docket enjoins Apple from implementing its new anticompetitive acts to keep away from compliance with the Injunction. Efficient instantly Apple will not impede builders’ means to speak with customers nor will they levy or impose a brand new fee on off-app purchases.

And time really is of the essence: in the present day, Stripe launched an extension of its off-platform app funds choice that enables for native, in-app checkout on iOS (see this video to know how seamless the method is). Clearly, Stripe anticipated this final result as an eventuality. And I’m sure that each app developer is presently investigating how they’ll launch off-platform funds.

I’ve persistently maintained that Apple has the appropriate to cost no matter payment it chooses for App Retailer funds — see Three arguments in opposition to Apple anti-trust accusations for my arguments. I don’t begrudge Apple’s declare on App Retailer commissions, given the central function it performs in facilitating them. However Apple’s efforts to impede off-platform funds have been past the pale, as I’ve detailed over the previous few years within the Heads I win, Tails you lose collection. This improvement is simply and overdue.

JetBrains open sources its code completion LLM, Mellum


JetBrains has introduced that its code completion LLM, Mellum, is now out there on Hugging Face as an open supply mannequin.

In line with the corporate, Mellum is a “focal mannequin,” that means that it was constructed purposely for a selected process, moderately than attempting to be good at the whole lot. “It’s designed to do one factor rather well: code completion,” Anton Semenkin, senior product supervisor at JetBrains, and Michelle Frost, AI advocate at JetBrains, wrote in a weblog publish. 

Focal fashions are usually cheaper to run than basic bigger fashions, which makes them extra accessible to groups that don’t have the sources to be operating massive fashions. 

“Consider it like T-shaped abilities – an idea the place an individual has a broad understanding throughout many subjects (the horizontal high bar or their breadth of data), however deep experience in a single particular space (the vertical stem or depth). Focal fashions comply with this similar concept: they aren’t constructed to deal with the whole lot. As a substitute, they specialize and excel at a single process the place depth actually delivers worth,” the authors wrote. 

Mellum at the moment helps code completion for a number of well-liked languages: Java, Kotlin, Python, Go, PHP, C, C++, C#, JavaScript, TypeScript, CSS, HTML, Rust, Ruby.

There are plans to develop Mellum right into a household of various focal fashions supreme for different particular coding duties, reminiscent of diff prediction. 

The present model of Mellum is most supreme for both AI/ML researchers exploring AI’s position in software program improvement, or AI/ML engineers or educators as a basis for studying the right way to construct, fine-tune, and adapt domain-specific language fashions. 

“Mellum isn’t a plug-and-play answer. By releasing it on Hugging Face, we’re providing researchers, educators, and superior groups the chance to discover how a purpose-built mannequin works underneath the hood,” the authors wrote.

reactjs – React Native iOS Construct Failed: fmt/src/format.cc compilation error after downloading Pod file


I’m engaged on a React Native mission, and after efficiently downloading the Pod file, I’m going through a construct failure when working the app on iOS. Right here’s what occurs:

  1. I run the next command to start out the app:

  2. rm -rf ios/Pods
rm -rf ios/DerivedData
rm -rf ~/Library/Developer/Xcode/DerivedData
cd ios && pod set up --repo-update && cd ..se64

  3. "ios:dev": "npx react-native run-ios --scheme 'VeeraHealthPcosDev' --configuration Debug --simulator="iPhone 13""

  4. The construct fails, and I get this error message:

    ** BUILD FAILED **


The next construct instructions failed:
        CompileC /Customers/rac/Library/Developer/Xcode/DerivedData/veerahealthpcos-fjsocvigquxpakdaumsxcfhhcmhw/Construct/Intermediates.noindex/Pods.construct/Debug-iphonesimulator/fmt.construct/Objects-normal/x86_64/format.o /Customers/rac/Desktop/working/rn-veera-health-pcos/ios/Pods/fmt/src/format.cc regular x86_64 c++ com.apple.compilers.llvm.clang.1_0.compiler (in goal 'fmt' from mission 'Pods')
        Constructing workspace veerahealthpcos with scheme VeeraHealthPcosDev and configuration Debug
(2 failures)

data Run CLI with --verbose flag for extra particulars.

Atmosphere:

I can’t replace to the most recent model of React Native, as my mission is dependent upon older package deal variations that aren’t appropriate with the most recent React Native model. I’ve tried cleansing the construct folder, reinstalling the dependencies, and even updating the Pods, however the difficulty persists.

I believe the issue could also be associated to the file ios/Pods/fmt/src/format.cc, however I’m unsure the way to resolve it. Has anybody else encountered this difficulty or have any strategies for an answer?

Contained in the post_install do |installer| block, I added the next to change the construct settings:

installer.pods_project.targets.every do |goal|
  goal.build_configurations.every do |config|
    # Enable arm64 (take away earlier exclusion of arm64):
    config.build_settings['EXCLUDED_ARCHS[sdk=iphonesimulator*]'] = 'x86_64'
    config.build_settings['ONLY_ACTIVE_ARCH'] = 'YES'
  finish
finish

installer.pods_project.targets.every do |goal|
  if goal.title == 'fmt'
    goal.build_configurations.every do |config|
      # Pressure C++17 (required by trendy fmt) and libc++  
      config.build_settings['CLANG_CXX_LANGUAGE_STANDARD'] = 'c++17'  
      config.build_settings['CLANG_CXX_LIBRARY'] = 'libc++'  
      # Disable Clang modules (can keep away from module import points)
      config.build_settings['CLANG_ENABLE_MODULES'] = 'NO'  
      config.build_settings['CLANG_MODULES_AUTOLINK'] = 'NO'  
      # (Non-obligatory) Add any wanted defines, e.g. for compatibility
      config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= ['$(inherited)', '_LIBCPP_ENABLE_CXX17_REMOVED_UNARY_BINARY_FUNCTION']
    finish
  finish
finish

installer.pods_project.targets.every do |goal|
  if goal.title == 'OneSignalNotificationServiceExtension'
    goal.build_configurations.every do |config|
      # Exclude x86_64 on simulator so we solely construct arm64
      config.build_settings['EXCLUDED_ARCHS[sdk=iphonesimulator*]'] = 'x86_64'
      # Solely construct the energetic arch in debug
      config.build_settings['ONLY_ACTIVE_ARCH'] = 'YES'
    finish
  finish
finish

After working the app, I anticipated the construct to succeed, however as an alternative, I acquired the next error:

The next construct instructions failed:
        SwiftEmitModule regular x86_64 Emitting module for OneSignalNotificationServiceExtension (in goal 'OneSignalNotificationServiceExtension' from mission 'xyz')
        SwiftCompile regular x86_64 /Customers/rac/Desktop/working/rn-veera-health-pcos/ios/OneSignalNotificationServiceExtension/NotificationService.swift (in goal 'OneSignalNotificationServiceExtension' from mission 'xyz')
        Constructing workspace xyz with scheme VeeraHealthPcosDev and configuration Debug
(3 failures)

It seems to be a problem associated to the OneSignalNotificationServiceExtension. Any strategies on the way to resolve this or repair the construct failure could be appreciated.
